See A. D'Ancona, Carteggio di Michele Amari coll' elogio di lui (Turin, 1896); and Oreste Tommasini's essay in his Scritti di storial e critica (Rome, 189I). (L. V.n)

AMARYLLIS (the name of a girl in classical pastoral poetry), in botany, a genus of the natural order Amaryllidaceae, containing the belladonna lily (Amaryllis Belladonna), a native of South Africa, which was introduced into cultivation at the beginning of the 18th century. This is a half-hardy bulbous plant, producing in the spring a number of strap-shaped, dull green leaves, 1-1 1/2 ft. long, arranged in two rows, and in autumn a solid stem, bearing at the top a cluster of 6-12 funnel-shaped flowers, of a rose colour and very fragrant. Several forms are known in cultivation. Most of the so-called Amaryllis of gardens belong to the allied genus Hippeastrum (q.v.).

AMASIA (anc. Amasia), the chief town of a sanjak in the Sivas vilayet of Asia Minor and an important trade centre on the Samsun-Sivas road, beautifully situated on the Yeshil Irmak (Iris). Pop. 30,000; Moslems about 20,000, of whom a large proportion are Kizilbash (Shia); Christians (mostly Armenians), 10,000. It was one of the chief towns of the kingdom of Trebizond and of the Seljuks, one of whose sultans, Kaikobad I., enriched it with fine buildings and restored the castle, which was thus enabled to stand a seven months' siege by Timur. It was also much favoured by the early Osmanli sultans, one of whom, Sclim I., was born there. Bayezid II. built a fine mosque. The place was modernized about a generation ago by Zia Pasha, the poet, when governor, and is now an unusually well built Turkish town with good bazaar and khans and a fine clock-tower. The Americans and the Jesuits have missionary schools for the Armenian population. Amasia has extensive orchards and fruit gardens still, as in Ibn Batuta's time, irrigated by water wheels turned by the current of the river; and there are steam flourmills. Wheat, flour and silk are exported.

Ancient Amasia has left little trace of itself except on the castle rock, on the left of the river, where the acropolis walls and a number of splendid rock-cut tombs, described by Strabo as those of the kings of Pontus, can be seen. The cliff is cut away all round these immense sepulchres so that they stand free. The finest, known from its polished surfaces as the "Mirror Tomb,'' is about 2 m. from the modern city. Amasia rose into historical importance after the time of Alexander as the cradle of the power of Pontus; but the last king to reign there was the father of Mithradates Eupator "The Great.'' The latter, however, made it the base of his operations against the Romans in 89, 72 and 67 B.C. Pompey made it a free city in 65, after Mithradates' fall. It was the birthplace of Strabo. (D. G. H.)

AMASIS, or AMOSIS (the Greek forms of the Egyptian name Ahmase, Ahmosi, "the moon is born,'' often written Aahmes or Ahmes in modern works), the name of two kings of ancient Egypt.

AMASIS I., the founder of the XVIIIth dynasty, is famous for his successful wars against the Hyksos princes who still ruled in the north-east of the Delta (see EGYPT: History, sect. 1.)

AMASIS II. was the last great ruler of Egypt before the Persian conquest, 570-526 B.C. Most of our information about him is derived from Herodotus (ii. 161 et seq.) and can only be imperfectly controlled by monumental evidence. According to the Greek historian he was of mean origin. A revolt of the native soldiers gave him his opportunity. These troops, returning home from a disastrous expedition to Cyrene, suspected that they had been betrayed in order that Apries, the reigning king, might rule more absolutely by means of his mercenaries, and their friends in Egypt fully sympathized with them. Amasis, sent to meet them and quell the revolt, was proclaimed king by the rebels, and Apries, who had now to rely entirely on his mercenaries, was defeated and taken prisoner in the ensuing conflict at Momemphis; the usurper treated the captive prince with great lenity, but was eventually persuaded to give him up to the people, by whom he was strangled and buried in his ancestral tomb at Sais. An inscription confirms the fact of the struggle between the native and the foreign soldiery, and proves that Apries was killed and honourably buried in the 3rd year of Amasis. Although Amasis thus appears first as champion of the disparaged native, he had the good sense to cultivate the friendship of the Greek world, and brought Egypt into closer touch with it than ever before. Herodotus relates that under his prudent administration Egypt reached the highest pitch of prosperity; he adorned the temples of Lower Egypt especially with splendid monolithic shrines and other monuments (his activity here is proved by remains still existing). To the Greeks Amasis assigned the commercial colony of Naucratis on the Canopic branch of the Nile, and when the temple of Delphi was burnt he contributed 1000 talents to the rebuilding. He also married a Greek princess named Ladice, the daughter of Battus, king of Cyrene, and he made alliances with Polycrates of Samos and Croesus of Lydia. His kingdom consisted probably of Egypt only, as far as the First Cataract, but to this he added Cyprus, and his influence was great in Cyrene. At the beginning of his long reign, before the death of Apries, he appears to have sustained an attack by Nebuchadrezzar (568 B.C.). Cyrus left Egypt unmolested; but the last years of Amasis were disturbed by the threatened invasion of Cambyses and by the rupture of the alliance with Polycrates of Samos. The blow fell upon his son Psammetichus III., whom the Persian deprived of his kingdom after a reign of only six months.

AMATEUR (Lat. amator, lover), a person who takes part in any art, craft, game or sport for the sake of the pleasure afforded

by the occupation itself and not for pecuniary gain. Being thus a person for whom the pursuit in question is a recreation and not a business, and who therefore presumably devotes to it a portion only of his leisure and not his working hours, the average amateur possesses less skill than the average professional, whose livelihood and reputation depend on his proficiency, and who therefore concentrates all his energies on the task of attaining the greatest possible mastery in his chosen career. In the arts, such as music, painting and the drama, the best amateurs are outdistanced as executants not merely by the best professionals but by professionals far below the highest rank; and although the inferiority of the amateur is not perhaps so pronounced or so universal in the case of games and outdoor sports, the records of such pastimes as horse-racing, boxing, rowing, billiards, tennis and golf prove that here also the same contrast is generally to be found. Hence it has come about that the term "amateur,'' and more especially the adjectival derivative "amateurish,'' has acquired a secondary meaning, usually employed somewhat contemptuously, signifying inefficiency, unskilfulness, superficial knowledge or training.

The immense increase in popularity of athletic contests and games of all kinds in modern times, and especially the keen competition for "records'' and championships, often of an international character, have made it a matter of importance to arrive at a clear and formal definition of the amateur as distinguished from the professional. The simple, straightforward definition of the amateur given above has been proved to be easily evaded. Many leading cricketers, for example, preserve their amateur status who, although they are not paid wages for each match they play like their professional colleagues, are provided with an annual income by their county or club under the guise of salary for performing the duties of "secretary'' or some other office, leaving them free to play the game six days a week. Similarly, "gentlemen riders'' are often presented with a cash payment described as a bet, or under some other pretext. Nor is the dividing-line between "out-of-pocket expenses'' allowed to the amateur and the remuneration payable to the professional always strictly drawn. The various associations controlling the different branches of sport have therefore devised working regulations to be observed so far as their jurisdiction extends. Thus the Amateur Athletic Association of Great Britain defines an amateur as "one who has never competed for a money prize or staked bet, or with or against a professional for any prize, or who has never taught, pursued or assisted in the practice of athletic exercises as a means of obtaining a livelihood.'' The rules of the Amateur Rowing Association are stricter, denying amateur status to anyone who has ever steered or rowed in a race with a professional for any prize, or who is or has been by trade or employment for wages a mechanic, artisan or labourer, or engaged in any menial duty, besides insisting upon the usual restrictions in regard to taking money and competing with professionals. In association football the rules are much more lax, for although amateurs are clearly distinguished from professionals, an amateur may even become a regular member, though unsalaried, of a professional team without losing his amateur status. The Rugby game was, up to 1895, entirely controlled by the Rugby Football Union, which, by the strictness of its laws, effectually prevented the growth of professionalism, but there had been much dissatisfaction in the provinces with the Union's decision against reimbursing day- working players for "broken time,'' i.e. for that part of their wages which they lost by playing on working days, and this resulted in the formation (1895) of the Northern Union, which permits remuneration for "broken time,'' but allows no person who works for his living to play football unless regularly employed at his particular trade.

In America the amateur question is less complicated than in Great Britain; but the intensely business-like character of American ideas of sport has encouraged the modern spirit of professionalism. All important sports in America, except baseball, football, cricket, golf and rowing, are, however, under the control of the Amateur Athletic Union of the United States, the rules of which, so far as they relate to professionalism, are as follows. No person shall be eligible to compete in any athletic meeting, game or entertainment, given or sanctioned by this Union, who has (1) received or competed for compensation or reward in any form for the display, exercise or example of his skill or knowledge of any athletic exercise, or for rendering personal service of any kind to any athletic organization, or for becoming or continuing a member of any athletic organization; or (2) has entered any competition under a name other than his own, or from a club of which he was not at that time a member in good standing; or (3) has knowingly entered any competition open to any professional or professionals, or has knowingly competed with any professional for any prize or token; or (4) has issued or allowed to be issued in his behalf any challenge to compete against any professional or for money; or (5) has pawned, bartered or sold any prize won in athletic competition. It will be seen that by rule 3 the American Union enacts a standard for all athletes not much different from that of the British Amateur Rowing Association. The rules for the sports not within the Union's jurisdiction are practically the same, except that in baseball, cricket and golf amateurs may compete with professionals, though not for cash prizes. In the case of open golf competitions professional prize-winners receive cash, while amateurs are given plate to the value of their prizes as in Great Britain. There are practically no professional football players in America.

On both sides of the Atlantic the question of the employment of professional coaches has occasioned much discussion. In America it has been accepted as legal. In England the same is almost universally true, but there are certain exceptions, such as the decision of the Henley Regatta Committee, that no crew entering may be coached by a professional within two months of the race-day. Whether such a regulation be wise or the reverse is a question that depends upon the spirit in which games are regarded. Nobody wants to disparage proficiency; but if a game is conducted on business methods, the "game'' element tends to be minimized, and if its object is pecuniary it ceases to be "sport'' in the old sense, and the old idea of the "amateur'' who indulges in it for love of the mere enjoyment tends to disappear.

AMATHUS, an ancient city of Cyprus, on the S. coast, about 24 m. W. of Larnaka and 6 m. E. of Limassol, among sandy hills and sand-dunes, which perhaps explain its name in Greek (amathos, sand). The earliest remains hitherto found on the site are tombs of the early Iron Age period of Graeco-Phoenician influences (1000-600 B.C.). Amathus is identified by some (E. Oberhummer, Die Insel Cypern, i., 1902, pp. 13-14; but see CITIUM) with Kartihadasti (Phoenician "New-Town'') in the Cypriote tribute-list of Esarhaddon of Assyria (668 B.C.). It certainly maintained strong Phoenician sympathies, for it was its refusal to join the phil-Hellene league of Onesilas of Salamis which provoked the revolt of Cyprus from Persia in 500-494 B.C. (Herod. v. 105), when Amathus was besieged unsuccessfully and avenged itself by the capture and execution of Onesilas. The phil-Hellene Evagoras of Salamis was similarly opposed by Amathus about 385-380 B.C. in conjunction with Citium and Soli (Diod. Sic. xiv. 98); and even after Alexander the city resisted annexation, and was bound over to give hostages to Seleucus (Diod. Sic. xix. 62). Its political importance now ended, but its temple of Adonis and Aphrodite (Venus Amathusia) remained famous in Roman time.

The wealth of Amathus was derived partly from its corn (Strabo 340, quoting Hipponax, fi. 540 B.C.), partly from its copper mines (Ovid, Met. x. 220, 531), of which traces can be seen inland (G. Mariti, i. 187; L. Ross, Inselreise, iv. 195; W. H. Engel, Kypros, i. 111 ff.). Ovid also mentions its sheep (Met. x. 227); the epithet Amathusia in Roman poetry often means little more than "Cypriote,'' attesting however the fame of the city.

Amathus still flourished and produced a distinguished patriarch of Alexandria (Johannes Eleemon), as late as 606-616, and a ruined Byzantine church marks the site; but it was already

almost deserted when Richard Coeur de Lion won Cyprus by a victory there over Isaac Comnenus in 1191. The rich necropolis, already partly plundered then, has yielded valuable works of art to New York (L. P. di Cesnola, Cyprus, 1878 passim) and to the British Museum (Excavations in Cyprus, 1894 (1899) passim); but the city has vanished, except fragments of wall and of a great stone cistern on the acropolis. A similar vessel was transported to the Louvre in 1867. Two small sanctuaries, with terra-cotta votive offerings of Graeco-Phoenician age, lie not far off, but the great shrine of Adonis and Aphrodite has not been identified (M. Ohnefalsch-Richter, Kypros, i. ch.1). (J. L. M.)

AMATI, the name of a family of Italian violin-makers, who flourished at Cremona from about 1550 to 1692. According to Fetis, Andrea and Nicolo Amati, two brothers, were the first Italians who made violins. They were succeeded by Antonio and Geronimo, sons of Nicolo. Another Nicolo, son of Geronimo, was born on the 3rd of September 1596 and died on the 12th of August 1684. He was the most eminent of the family. He improved the model adopted by the rest of the Amatis and produced instruments capable of yielding greater power of tone. His pattern was usually small, but he also made the so-called "Grand Amatis.'' Of his pupils the most famous were Andrea Enamieri and Antonio Stradivari.

AMATITLAN, or SAN JUAN DE AMATITLAN, the capital of a department bearing the same name in Guatemala, on Lake Amatitlan, 15 m. S.W. of Guatemala city by the transcontinental railway from Puerto Barrios to San Jose. Pop. (1905) about 10,000. The town consists almost entirely of one-storeyed adobe huts inhabited by mulattoes and Indians, whose chief industry is the production of cochineal. In 1840 only a small Indian village marked its site, and its subsequent growth was due to the sugar plantations established by a Jesuit settlement. The wells of the town are strongly impregnated with salt and alum, and in the vicinity there are several hot springs. Lake Amatitlan, 9 m. long and 3 m. broad, lies on the northern side of the great Guatemalan Cordillera. Above it rises the four- cratered volcano of Pacaya (8390 ft.), which was in eruption in 1870. The outlet of the lake is a swift river 65 m. long, which cuts a way through the Cordillera, and enters the Pacific at Istapa, after forming at San Pedro a fine waterfall more than 200 ft. high.

AMAUROSIS (Gr. for "blinding,''), a term for "deprivation of sight,'' limited chiefly to those forms of defect or loss of vision which are caused by diseases not directly involving the eye.

AMAZON, the great river of South America. Before the conquest of South America, the Rio de las Amazonas had no general name; for, according to a common custom, each savage tribe gave a name only to the section of the river which it occupied — such as Paranaguazu, Guyerma, Sclimoes and others. In the year 1500, Vicente Yanez Pinzon, in command of a Spanish expedition, discovered and ascended the Amazon to a point about 50 m. from the sea. He called it the Rio Santa Maria de la Mar Dulce, which soon became abbreviated to Mar Dulce, and for some years, after 1502, it was known as the Rio Grande. The principal companions of Pinzon, in giving evidence in 1513, mention it as El Ryo Haranon. There is much controversy about the origin of the word Maranon. Peter Martyr in a letter to Lope Hurtado de Mendoza in 1513 is the first to state that it is of native origin. Ten years after the death of Pinzon, his friend Oviedo calls it the Maranon. Many writers believe that this was its Indian name. We are disposed to agree with the Brazilian historian Constancio that Maranon is derived from the Spanish word marana, a tangle, a snarl, which well represents the bewildering difficulties which the earlier explorers met in navigating not only the entrance to the Amazon, but the whole island-bordered, river-cut and indented coast of the now Brazilian province of Maranhao.

The first descent of the mighty artery from the Andes to the sea was made by Orellana in 1541, and the name Amazonas arises from the battle which he had with a tribe of Tapuya savages where the women of the tribe fought alongside the men, as was the custom among all of the Tapuyas. Orellana, no doubt, derived the name Amazonas from the ancient Amazons (q.v.) of Asia and Africa described by Herodotusand Diodorus.

The first ascent of the river was made in 1638 by Pedro Texiera, a Portuguese, who reversed the route of Orellana and reached Quito by way of the Rio Napo. He returned in 1639 with the Jesuit fathers Acuna and Artieda, delegated by the viceroy of Peru to accompany him.

The river Amazon has a drainage area of 2,722,000 sq. m., if the Tocantins be included in its basin. It drains four-tenths of South America, and it gathers its waters from 5 deg. N. to 20 deg. S. latitude. Its most remote sources are found on the inter-Andean plateau, but a short distance from the Pacific Ocean; and, after a course of about 4000 m. through the interior of Peru and across Brazil, it enters the Atlantic Ocean on the equator. It is generally accepted by geographers that the Maranon, or Upper Amazon, rises in the little lake, Lauricocha, in 10 deg. 30' S. latitude, and 100 m. N.N.E. of Lima. They appear to have followed the account given by Padre Fritz which has since been found incorrect. According to Antonio Raimondi, it is the Rio de Nupe branch of the small stream which issues from the lake that has the longer course and the greater volume of water. The Nupe rises in the Cordillera de Huayhuath and is the true source of the Maranon. There is a difference among geographers as to where the Maranon ends and the Amazon begins, or whether both names apply to the same river. The Pongo de Manseriche, at the base of the Andes and the head of useful navigation, seems to be the natural terminus of the Maranon; and an examination of the hydrographic conditions of the great valley makes the convenience and accuracy of this apparent. Raimondi terminates the Maranon at the mouth of the Ucayali, Reclus the same, both following the missionary fathers of the colonial period. C. M. de la Condamine uses "Amazon'' and "Maranon'' indiscriminately and considers them one and the same. Smyth and Lowe give the mouth of the Javary as the eastern limit, as does d'Orbigny. Wolf, apparently uncertain, carries the "Maranon or Amazon'' to the Peruvian frontier of Brazil at Tabatinga. Other travellers and explorers contribute to the confusion. This probably arises from the rivalry of the Spaniards and Portuguese. The former accepted the name Maranon in Peru, and as the missionaries penetrated the valley they extended the name until they reached the mouth of the Ucayali; while, as the Portuguese ascended the Amazon, they carried this name to the extent of their explorations. Beginning with the lower river we propose to notice, first, the great affluents which go to swell the volume of the main stream.

Tributaries.

The TOCANTINS is not really a branch of the Amazon, although usually so considered. It is the central fluvial artery of Brazil, running from south to north for a distance of about 1500 m. It rises in the mountainous district known as the Pyreneos; but its more ambitious western affluent, the Araguay, has its extreme southern headwaters on the slopes of the Serra Cayapo, and flows a distance of 1080 m. before its junction with the parent stream, which it appears almost to equal in volume. Besides its main tributary, the Rio das Mortes, it has twenty smaller branches, offering many miles of canoe navigation. In finding its way to the lowlands, it breaks frequently into falls and rapids, or winds violently through rocky gorges, until, at a point about 100 m. above its junction with the Tocantins, it saws its way across a rocky dyke for 12 m. in roaring cataracts. The tributaries of the Tocantins, called the Maranhao and Parana-tinga, collect an immense volume of water from the highlands which surround them, especially on the south and south-east. Between the latter and the confluence with the Araguay, the Tocantins is occasionally obstructed by rocky barriers which cross it almost at a right angle. Through these, the river carves its channel, broken into cataracts and rapids, or cachoeiras, as they are called throughout Brazil. Its lowest one, the Itaboca cataract, is about 130 m. above its estuarine port of Cameta, for which distance the river is navigable; but above that it is useless as a commercial avenue, except for laborious and very costly transportation.

The flat, broad valleys, composed of sand and clay, of both the Tocantins and its Araguay branch are overlooked by steep bluffs. They are the margins of the great sandstone plateaus, from 1000 to 2000 ft. elevation above sea-level, through which the rivers have eroded their deep beds. Around the estuary of the Tocantins the great plateau has disappeared, to give place to a part of the forest-covered, half submerged alluvial plain, which extends far to the north-east and west. The Para river, generally called one of the mouths of the Amazon, is only the lower reach of the Tocantins. If any portion of the waters of the Amazon runs round the southern side of the large island of Marajo into the river Para, it is only through tortuous, natural canals, which are in no sense outflow channels of the Amazon.

The XINGU, the next large river west of the Tocantins, is a true tributary of the Amazon. It was but little known until it was explored in 1884-1887 by Karl von den Steinen from Cuyaba. Travelling east, 240 m., he found the river Tamitatoaba, 180 ft. wide, flowing from a lake 25 m. in diameter. He descended this torrential stream to the river Romero, 1300 ft. wide, entering from the west, which receives the river Colisu. These three streams form the Xingu, or Parana-xingu, which, from 73 m. lower down, bounds along a succession of rapids for 400 m. A little above the head of navigation, 105 m. from its mouth, the river makes a bend to the east to find its way across a rocky barrier. Here is the great cataract of Itamaraca, which rushes down an inchned plane for 3 m. and then gives a final leap, called the fall of Itamaraca. Near its mouth, the Xingu expands into an immense lake, and its waters then mingle with those of the Amazon through a labyrinth of eanos (natural canals), winding in countless directions through a wooded archipelago.

The TAPAHOS, running through a humid, hot and unhealthy valley, pours into the Amazon 500 m. above Para and is about 1200 m. long. It rises on the lofty Brazilian plateau near Diamantino in 14 deg. 25' S. lat. Near this place a number of streams unite to form the river Arinos, which at latitude 10 deg. 25' joins the Juruena to form the Alto Tapajos, so called as low down as the Rio Manoel, entering from the east. Thence to Santarem the stream is known as the Tapajos. The lower Arinos, the Alto Tapajos and the Tapajos to the last rapid, the Maranhao Grande, is a continuous series of formidable cataracts and rapids; but from the Maranhao Grande to its mouth, about 188 m., the river can be navigated by largevessels. For its last 100 mi. it is from 4 to 9 m. wide and much of it very deep. The valley of the Tapajos is bordered on both sides by bluffs. They are from 300 to 400 ft. high along the lower river; but, a few miles above Santarem, they retire from the eastern side and only approach the Amazon flood-plain some miles below Santarem.

The MADEIRA has its junction with the Amazon 870 mi. by river above Para, and almost rivals it in the volume of its waters. It rises more than 50 ft. during the rainy season, and the largest ocean steamers may ascend it to the Fall of San Antonio, 663 m. above its mouth; but in the dry months, from June to November, it is only navigable for the same distance for craft drawing from 5 to 6 ft. of water. According to the treaty of San Ildefonso, the Madeira begins at the confluence of the Guapore with the Mamore. Both of these streams have their headwaters almost in contact with those of the river Paraguay. The idea of a connecting canal is based on ignorance of local conditions. San Antonio is the first of a formidable series of cataracts and rapids, nineteen in number, which, for a river distance of 263 m., obstruct the upper course of the Madeira until the last rapid called Guajara Merim (or Small Pebble), is reached, a little below the union of the Guapore with the Mamore. The junction of the great river Beni with the Madeira is at the Madeira Fall, a vast and grand display ofreefs, whirlpools and boiling torrents. Between Guajara-Merim and this fall, inclusive, the Madeira receives the drainage of the northeastern slopes of the Andes, from Santa Cruz de la Sierra to Cuzco, the whole of the south-western slope of Brazilian Matto (irosso and the northern one of the Chiquitos sierras, an area about

equal to that of France and Spain. The waters find their way to the falls of the Madeira by many great rivers, the principal of which, if we enumerate them from east to west, are the Guapore or Itenez, the Baures and Blanco, the Itonama or San Miguel, the Mamore, Beni, and Mayutata or Madre de Dios, all of which are reinforced by numerous secondary but powerful affluents. The Guapore presents many difficulties to continuous navigation; the Baures and Itonama offer hundreds of miles of navigable waters through beautiful plains; the Mamore has been sounded by the writer in the driest month of the year for a distance of 500 m. above Guajara-Merim, who found never less than from 10 to 30 ft. of water, with a current of from 1 to 3 m. an hour. Its Rio Grande branch, explored under the writer's instructions, was found navigable for craft drawing 3 ft. of water to within 30 m. of Santa Cruz de la Sierra — a level sandy plain intervening. The Grande is a river of enormous length, rising in a great valley of the Andes between the important cities of Sucre and Cochabamba, and having its upper waters in close touch with those of the Pilcomayo branch of the river Paraguay. It makes a long curve through the mountains, and, after a course of about 800 m., joins the Mamore near 15 deg. S. lat. The Chapare, Secure and Chimore, tributaries of the Mamore, are navigable for launches up to the base of the mountains, to within 130 m. of Cochabamba. The Beni has a 12-ft. fall 18 m. above its mouth called "La Esperanza''; beyond this, it is navigable for 217 m. to the port of Reyes for launches in the dry season and larger craft in the wet one. The extreme source of the Beni is the little river La Paz, which rises in the inter-Andean region, a few miles south-east of Lake Titicaca, and flows as a rivulet through the Bolivian city of La Paz. From this point to Reyes the river is a torrent. The principal affluent of the Beni, and one which exceeds it in volume, enters it 120 m. above its mouth, and is known to the Indians along its banks as the Mayutata, but the Peruvians

call it the Madre de Dios. Its ramifications drain the slopes of the Andes between 12 deg. and 15 deg. of latitude. It is navigable in the wet season to within 180 m. of Cuzco. Its upper waters are separated by only a short transitable canoe portage of 7 m. in a straight line from those of the Ucayali. The portage on the eastern side terminates at the Cashpajah river 22 m. above its junction with the Manu. For the first 13 m. it is navigable all the year for craft drawing 18 in. of water, but the remaining 9 m. present many obstacles to navigation. At the Manu junction the elevation above sea-level is 1070 ft., the river width 300 ft., depth 8 ft., current 1 1/4 m. per hour. The general direction of the Manu is south-east for 158 m. as far as the Pilcopata river, where under the name of Madre de Dios it continues with a flow of 22,000 cubic metres per minute. Here its elevation is 718 ft. above the sea and its width 500 ft. During the above course of 158 m. the Manu receives 135 large and small affluents. Although the inclination of its bed is not great, the obstacles to free navigation are abundant, and consist of enormous trees and masses of tree-trunks which have filled the river during the period of freshets.

From the time it receives the Manu, the Madre de Dios carries its immense volume of waters 485 m. to the Beni over the extremely easy slope of a vast and fertile plain. Its banks are low, its bottom pebbly. A greater part of its course is filled with large and small islands some 63 in number. Its average width is about 1500 ft. Below the mouth of the Tambopata, the flow is estimated at 191,250 cubic metres per minute. The average current is 2 1/2 m. per hour. There are two important rapids and one cataract on the lower 300 m. of the river.

The Mayutata receives three principal tributaries from the south — the Tambopata, Inambari and Pilcopata.

The Peruvian government has sought to open a trade route between the Rio Ucayali and the rich rubber districts of the Mayutata. All of the upper branches of the river Madeira find their way to the falls across the open, almost level Mojos and Beni plains, 35,000 sq. m. of which are yearly flooded to an average depth of about 3 ft. for a period of from three to four months. They rival if they do not exceed in fertility the valley of the Nile, and are the healthiest and most inviting agricultural and grazing region of the basin of the Amazon.

The PURUS, a very sluggish river, enters the Amazon west of the Madeira, which it parallels as far south as the falls of the latter stream. It runs through a continuous forest at the bottom of the great depression lying between the Madeira river, which skirts the edge of the Brazilian sandstone plateau, and the Ucayali which hugs the base of the Andes. One of its marked features is the five parallel furos1 which from the north-west at almost regular intervals the Amazon sends to the Purus; the most south-westerly one being about 150 m. above the mouth of the latter river. They cut a great area of very low-lying country into five islands. Farther down the Purfis to the right three smaller furos also connect it with the Amazon. Chandless found its elevation above sea-level to be only 107 ft. 590 m. from its mouth. It is one of the most crooked streams in the world, and its length in a straight line is less than half that by its curves. It is practically only a drainage ditch for the half-submerged, lake-flooded district it traverses. Its width is very uniform for 1000 m. up, and for 800 m. its depth is never less than 45 ft. It is navigable by steamers for 1648 m. as far as the little stream, the Curumaha, but only by light-draft craft. Chandless ascended it 1866 m. At 1792 m. it forks into two small streams. Occasionally a cliff touches the river, but in general the lands are subject to yearly inundations throughout its course, the river rising at times above 50 ft., the numerous lakes to the right and left serving as reservoirs. Its main tributary, the Aquiry or Acre, enters from the right about 1104 m. from the Amazon. Its sources are near those of the Mayutata. It is navigable for a period of about five months of the year, when the Purus valley is inundated; and, for the remaining seven months, only canoes can ascend it sufficiently high to communicate overland with the settlements in the great india-rubber districts of the Mayutata and lower Beni; thus these regions are forced to seek a canoe outlet for their rich products by the very dangerous, costly and laborious route of the falls of the Madeira.

The JURUA is the next great southern affluent of the Amazon west of the Purus, sharing with this the bottom of the immense inland Amazon depression, and having all the characteristics of the Purus as regards curvature, sluggishness and general features of the low, half-flooded forest country it traverses. It rises among the Ucayali highlands, and is navigable and unobstructed for a distance of 1133 m. above its junction with the Amazon.

The Javary, the boundary line between Brazil and Peru, is another Amazon tributary of importance. It is supposed to be navigable by canoe for 900 m. above its mouth to its sources among the Ucayali highlands, but only 260 have been found suitable for steam navigation. The Brazilian Boundary Commission ascended it in 1866 to the junction of the Shino with its Jaquirana branch. The country it traverses in its extremely sinuous course is very level, similar in character to that of the Jurua, and is a fostered wilderness occupied by a few savage hordes.

The UCAYALI, which rises only about 70 m. north of Lake Titicaca, is the most interesting branch of the Amazon next to the Madeira. The Ucayali was first called the San Miguel, then the Ucayali, Ucayare, Poro, Apu-Poro, Cocama and Rio de Cuzco. Peru has fitted out many costly and ably-conducted expeditions to explore it. One of them (1867) claimed to have reached within 240 m. of Lima, and the little steamer "Napo'' forced its way up the violent currents for 77 m. above the junction with the Pachitea river as far as the river Tambo, 770 m. from the confluence of the Ucayali with the Amazon. The "Napo'' then succeeded in ascending the Urubamba branch of the Ucayali 35 m. above its union with the Tambo, to a point 200 m. north of Cuzco. The remainder of the Urubamba, as shown by Bosquet in 1806 and Castelnau in 1846, is interrupted by cascades, reefs and numberless other obstacles to navigation. Senor Torres, who explored the Alto Ucayali for the Peruvian government, gives it a length of 186 m., counting from the mouth of the Pachitea to the junction of the Tambo and Urubamba. Its width varies from 1300 to 4000 ft., due to the great number of islands. The current runs from 3 to 4 m. an hour, and a channel from 60 to 150 ft. wide can always be found with a minimum depth of 5 ft. There are five bad passes, due to the accumulation of trees and rafts of timber. Sometimes enormous rocks have fallen from the mountains and spread over the river-bed causing huge whirlpools. "No greater difficulties present themselves to navigation by 10-knot steamers drawing 4 ft. of water.''

The TAMBO, which rises in the Vilcanota knot of mountains south of Cuzco, is a torrential stream valueless for commercial purposes. The banks of the Ucayali for 500 m. up are low, and in the rainy season extensively inundated.

The HUALLAGA (also known as the Guallaga and Rio de los Motilones), which joins the Amazon to the west of the Ucayali, rises high among the mountains, in about 10 deg. 40' S. lat., on the northern slopes of the celebrated Cerro de Pasco. For nearly its entire length it is an impetuous torrent running through a succession of gorges. It has forty-two rapids, its last obstruction being the Pongo de Aguirre, so called from the traitor Aguirre who passed there. To this point, 140 m. from the Amazon, the Huallaga can be ascended by large river steamers. Between the Huallaga and the Ucayali lies the famous "Pampa del Sacramento,'' a level region of stoneless alluvial lands covered with thick, dark forests, first entered by the missionaries in 1726. It is about 300 m. long, from north to south, and varies in width from 40 to 100 m. Many streams, navigable for canoes, penetrate this region from the Ucayali and the Huallaga. It is still occupied by savage tribes.

The river MARANON rises about 100 m. to the north-east of Lima. It flows through a deeply-eroded Andean valley in a north-west direction, along the eastern base of the Cordillera of the Andes, as far as 5 deg. 36' S. lat.; then it makes a great bend to the north-east, and with irresistible power cuts through the inland Andes, until at the Pongo de Manseriche2 it victoriously breaks away from the mountains to flow onwards through the plains under the name of the Amazon. Barred by reefs, and full of rapids and impetuous currents, it cannot become a commercial avenue. At the point where it makes its great bend the river Chinchipe pours into it from southern Ecuador. Just below this the mountains close in on either side of the Marapon, forming narrows or pongos for a length of 35 m., where, besides numerous whirlpools, there are no less than thirty-five formidable rapids, the series concluding with three cataracts just before reaching the river Imasa or Chunchunga, near the mouth of which La Condamine embarked in the 18th century to descend the Amazon. Here the general level of the country begins to decrease in elevation, with only a few mountain spurs, which from time to time push as far as the river and form pongos of minor importance and less dangerous to descend. Finally, after passing the narrows of Guaracayo, the cerros gradually disappear, and for a distance of about 20 m. the river is full of islands, and there is nothing visible from its low banks but an immense forest-covered plain. But the last barrier has yet to be passed, the Pongo de Manseriche, 3 m. long, just below the mouth of the Rio Santiago, and between it and the old abandoned missionary station of Borja, in 38 deg. 30' S. lat. and 77 deg. 30' 40'' W. long. According to Captain Carbajal, who descended it in the little steamer "Napo,' in 1868, it is a vast rent in the Andes about 2000 ft. deep, narrowing in places to a width of only 100 ft., the precipices "seeming to close in at the top.'' Through this dark canon the Maranon leaps along, at times, at the rate of 12 m. an hour3. The Pongo de Manseriche was first discovered by the Adelantado Joan de Salinas. He fitted out an expedition at Loxa in Ecuador, descended the Rio Santiago to the Maranon, passed through the perilous Pongo in 1557 and invaded the country of the Maynas Indians. Later, the missionaries of Cuenca and Quito established many missions in the Pais de los Maynas, and made extensive use of the Pongo de Manseriche as an avenue of communication with their several convents on the Andean plateau. According to their accounts, the huge rent in the Andes, the Pongo, is about five or six m. long, and in places not more than 80 ft. wide, and is a frightful series of torrents and whirlpools interspersed with rocks. There is an ancient tradition of the savages of the vicinity that one of their gods descending the Maranon and another ascending the Amazon to communicate with him, they opened the pass called the Pongo de Manseriche. From the northern slope of its basin the Amazon receives many tributaries, but their combined volume of water is not nearly so great as that contributed to the parent stream by its affluents from the south. That part of Brazil lying between the Amazon and French, Dutch and British Guiana, and bounded on the west by the Rio Negro, is known as Brazilian Guiana. It is the southern watershed of a tortuous, low chain of mountains running, roughly, east and west. Their northern slope, which is occupied by the three Guianas first named, is saturated and river-torn; but their southern one, Brazilian Guiana, is in general thirsty and semi-barren, and the driest region of the Amazon valley. It is an area which has been left almost in the undisturbed possession of nomadic Indian tribes, whose scanty numbers find it difficult to solve the food problem. From the divortium aquarum between French Guiana and Brazil, known as the Tumuc-humac range of highlands, two minor streams, the Yary and the Parou, reach the Amazon across the intervening broken and barren tableland. They are full of rapids and reefs.

The TROMBETAS is the first river of importance we meet on the northern side as we ascend the Amazon. Its confluence with this is just above the town of Obidos. It has its sources in the Guiana highlands, but its long course is frequently interrupted by violent currents, rocky barriers, and rapids. The inferior zone of the river, as far up as the first fall, the Porteira, has but little broken water and is low and swampy; but above the long series of cataracts and rapids the character and aspect of the valley completely change, and the climate is much better. The river is navigable for 135 m. above its mouth.

The NEGRO, the great northern tributary of the Amazon, has its sources along the watershed between the Orinoco and the Amazon basins, and also connects with the Orinoco by way of the Casiquiare canal. Its main affluent is the Uaupes, which disputes with the headwaters of the Guaviari branch of the Orinoco the drainage of the eastern slope of the "Oriental', Andes of Colombia. The Negro is navigable for 450 m. above its mouth for 4 ft. of water in the dry season, but it has many sandbanks and minor difficulties. In the wet season, it overflows the country far and wide, sometimes to a breadth of 20 m., for long distances, and for 400 m. up, as far as Santa Isabella, is a succession of lagoons, full of long islands and intricate channels, and the slope of the country is so gentle that the river has almost no current. But just before reaching the Uaupes there is a long series of reefs, over which it violently flows in cataracts, rapids and whirlpools. The Uaupes is full of similar obstacles, some fifty rapids barring its navigation, although a long stretch of its upper course is said to be free from them, and to flow gently through a forested country. Despite the impediments, canoes ascend this stream to the Andes.

The Branco is the principal affluent of the Negro from the north; it is enriched by many streams from the sierras which separate Venezuela and British Guiana from Brazil. Its two upper main tributaries are the Urariquira and the Takutu. The latter almost links its sources with those of the Essequibo. The Branco flows nearly south, and finds its way into the Negro through several channels and a chain of lagoons similar to those of the latter river. It is 350 m. long, up to its Urariquira confluence. It has numerous islands, and, 235 m. above its mouth, it is broken by a bad series of rapids.

CASIQUIARE CANAL. In 1744 the Jesuit Father Roman, while ascending the Orinoco river, met some Portuguese slave-traders from the settlements on the Rio Negro. He accompanied them on their return, by way of the Casiquiare canal, and afterwards retraced his route to the Orinoco. La Condamine, seven months later, was able to give to the French Academy an account of Father Roman's extraordinary voyage, and thus confirm the existence of this wonderful waterway first reported by Father Acuna in 1639. But little credence was given to Father Roman's statement until it was verified, in 1756, by the Spanish Boundary-line Commission of Yturriaga y Solano. The actual elevation of the canal above sea-level is not known, but is of primary importance to the study of the hydrography of South America. Travellers in general give it at from 400 to 900 ft., but, after much study of the question of altitudes throughout South America, the writer believes that it does not exceed 300 ft. The canal connects the upper Orinoco, 9 m. below the mission of Esmeraldas, with the Rio Negro affluent of the Amazon near the town of San Carlos. The general course is south-west, and its length, including windings, is about 200 m. Its width, at its bifurcation with the Orinoco, is approximately 300 ft., with a current towards the Negro of three-quarters of a mile an hour; but as it gains in volume from the very numerous tributary streams, large and small, which it receives en route, its velocity increases, and in the wet season reaches 5 and even 8 m. an hour in certain stretches. It broadens considerably as it approaches its mouth, where it is about 1750 ft. in width. It will thus be seen that the volume of water it captures from the Orinoco is small in comparison to what it accumulates in its course. In flood-time it is said to have a second connexion with the Rio Negro by a branch which it throws off to the westward called the Itinivini, which leaves it at a point about 50 m. above its mouth. In the dry season it has shallows, and is obstructed by sandbanks, a few rapids and granite rocks. Its shores are densely wooded, and the soil more fertile than that along the Rio Negro. The general slope of the plains through which the canal runs is south-west, but those of the Rio Negro slope south-east. The whole line of the Casiquiare is infested with myriads of tormenting insects. A few miserable groups of Indians and half-breeds have their small villages along its southern portion. It is thus seen that this marvellous freak of nature is not, as is generally supposed, a sluggish canal on a flat tableland, but a great, rapid river which, if its upper waters had not found contact with the Orinoco, perhaps by cutting back, would belong entirely to the Negro branch of the Amazon. To the west of the Casiquiare there is a much shorter and more facile connexion between the Orinoco and Amazon basins, called the isthmus of Pimichin, which is reached by ascending the Terni branch of the Atabapo affluent of the Orinoco. Although the Terni is somewhat obstructed, it is believed that it could easily be made navigable for small craft. The isthmus is 10 m. across, with undulating ground, nowhere over 50 ft. high, with swamps and marshes. It is much used for the transit of large canoes, which are hauled across it from the Terni river, and which reach the Negro by the little stream called the Pimichin.

The YAPURA. West of the Negro the Amazon receives three more imposing streams from the north-west — the Yapura, the Ica or Putumayo, and the Napo. The first was formerly known as the Hyapora, but its Brazilian part is now called the Yapura, and its Colombian portion the Caqueta. Barao de Marajo gives it 600 m. of navigable stretches. Jules Crevaux, who descended it, describes it as full of obstacles to navigation, the current very strong and the stream frequently interrupted by rapids and cataracts. It rises in the Colombian Andes, nearly in touch with the sources of the Magdalena, and augments its volume from many branches as it courses through Colombia. It was long supposed to have eight mouths; but Ribeiro de Sampaio, in his voyage of 1774, determined that there was but one real mouth, and that the supposed others are all furos or canos4 In 1864-1868 the Brazilian government made a somewhat careful examination of the Brazilian part of the river, as far up as the rapid of Cupaty. Several very easy and almost complete water-routes exist between the Yapura and Negro across the low, flat intervening country. Barao de Marajo says there are six of them, and one which connects the upper Yapura with the Uaupes branch of the Negro; thus the Indian tribes of the respective valleys have facile contact with each other.

The ICA or PUTUMAYO, west of and parallel to the Yapura, was found more agreeable to navigate by Crevaux. He ascended it in a steamer drawing 6 ft. of water, and running day and night. He reached Cuemby, 800 m. above its mouth, without finding a single rapid. Cuemby is only 200 m. from the Pacific Ocean, in a straight line, passing through the town of Pasto in southern Colombia. There was not a stone to be seen up to the base of the Andes; the river banks were of argillaceous earth and the bottom of fine sand.

The NAPO rises on the flanks of the volcanoes of Antisana, Sincholagua and Cotopaxi. Before it reaches the plains it receives a great number of small streams from impenetrable, saturated and much broken mountainous districts, where the dense and varied vegetation seems to fight for every square foot of ground. From the north it is joined by the river Coca, having its sources in the gorges of Cayambe on the equator, and also a powerful river, the Aguarico, having its headwaters between Cayambe and the Colombian frontier. From the west it receives a secondary tributary, the Curaray, from the Andean slopes, between Cotopaxi and the volcano of Tunguragua. From its Coca branch to the mouth of the Curaray the Napo is full of snags and shelving sandbanks, and throws out numerous canos among jungle-tangled islands, which in the wet season are flooded, giving the river an immense width. From the Coca to the Amazon it runs through a forested plain where not a hill is visible from the river — its uniformly level banks being only interrupted by swamps and lagoons. From the Amazon the Napo is navigable for river craft up to its Curaray branch, a distance of about 216 m., and perhaps a few miles farther; thence, by painful canoe navigation, its upper waters may be ascended as far as Santa Rosa, the usual point of embarkation for any venturesome traveller who descends from the Quito tableland. The Coca river may be penetrated as far up as its middle course, where it is jammed between two mountain walls, in a deep canyon, along which it dashes over high falls and numerous reefs. This is the stream made famous by the expedition of Gonzalo Pizarro.

The NANAY is the next Amazon tributary of importance west of the Napo. It belongs entirely to the lowlands, and is very crooked, has a slow current and divides much into canos and strings of lagoons which flood the flat, low areas of country on either side. It is simply the drainage ditch of districts which are extensively overflowed in the rainy season. Captain Butt ascended it 195 m., to near its source.

The TIGRE is the next west of the Nanay, and is navigable for 125 m. from its confluence with the Amazon. Like the Nanay, it belongs wholly to the plains. Its mouth is 42 m. west of the junction of the Ucayali with the Amazon. Continuing west from the Tigre we have the Parinari, Chambira, and Nucuray, all short lowland streams, resembling the Nanay in character.

The PASTAZA (the ancient river Sumatara) is the next large river we meet. It rises on the Ecuadorian tableland, where a branch from the valley of Riobamba unites with one from the Latacunga basin and breaks through the inland range of the Andes; and joined, afterwards, by several important tributaries, finds its way south-east among the gorges; thence it turns southward into the plains, and enters the Amazon at a point about 60 m. west of the mouth of the Huallaga. So far as known, it is a stream of no value except for canoe navigation. Its rise and fall are rapid and uncertain, and it is shallow and full of sandbanks and snags. It is a terrible river when in flood.

The MORONA flows parallel to the Pastaza and immediately to the west of it, and is the last stream of any importance on the northern side of the Amazon before reaching the Pongo de Manseriche. It is formed from a multitude of water-courses which descend the slopes of the Ecuadorian Andes south of the gigantic volcano of Sangay; but it soon reaches the plain, which commences where it receives its Cusulima branch. The MORONA is navigable for small craft for about 300 m. above its mouth, but it is extremely tortuous. Canoes may ascend many of its branches, especially the Cusuhma and the Miazal, the latter almost to the base of Sangay. The Morona has been the scene of many rude explorations, with the hope of finding it serviceable as a commercial route between the inter-Andean tableland of Ecuador and the Amazon river. A river called the Paute dashes through the eastern Andes from the valley of Cuenca; and a second, the Zamora, has broken through the same range from the basin of Loja. Swollen by their many affluents, they reach the lowlands and unite their waters to form the Santiago, which flows into the Maranon at the head of the Pongo de Manseriche. There is but little known of a trustworthy character regarding this river, but Wolf says that it is probably navigable up to the junction of the Paute with the Zamora.

The Main River.

Physical characteristics.

The AMAZON MAIN RIVER is navigable for ocean steamers as far as Iquitos, 2300 m. from the sea, and 486 m. higher up for vessels drawing 14 ft. of water, as far as Achual Point. Beyond that, according to Tucker, confirmed by Wertheman, it is unsafe; but small steamers frequently ascend to the Pongo de Manseriche, just above Achual Point The average current of the Amazon is about 3 m. an hour; but, especially in flood, it dashes through some of its contracted channels at the rate of 5 m. The U.S. steamer "Wilmington'' ascended it to Iquitos in 1899. Commander Todd reports that the average depth of the river in the height of the rainy season is 120 ft. It commences to rise in November, and increases in volume until June, and then falls until the end of October. The rise of the Negro branch is not synchronous; for the steady rains do not commence in its valley until February or March. By June it is full, and then it begins to fall with the Amazon. According to Bates, the Madeira "rises and sinks'' two months earlier than the Amazon. The Amazon at times broadens to 4 and 6 m. Occasionally, for long distances, it divides into two main streams with inland, lateral channels, all connected by a complicated system of natural canals, cutting the low, flat igapo lands, which are never more than 15 ft. above low river, into almost numberless islands.5 At the narrows of Obidos, 400 m. from the sea, it is compressed into a single bed a mile wide and over 200 ft. deep, through which the water rushes at the rate of 4 to 5 m. an hour. In the rainy season it inundates the country throughout its course to the extent of several hundred thousand square miles, covering the flood-plain, called vargem. The flood-levels are in places from 40 to 50 ft. high above low river. Taking four roughly equidistant places, the rise at Iquitos is 20 ft., at Teffe 45, near Obidos 35, and at Para 12 ft.

The first high land met in ascending the river is on the north bank, opposite the mouth of the Xingu, and extends for about 150 m. up, as far as Monte Alegre. It is a series of steep, table-topped hills, cut down to a kind of terrace which lies between them and the river. Monte Alegre reaches an altitude of several hundred feet. On the south side, above the Xingu, a line of low bluffs extends, in a series of gentle curves with hardly any breaks nearly to Santarem, but a considerable distance inland, bordering the flood-plain, which is many miles wide. Then they bend to the south-west, and, abutting upon the lower Tapajos, merge into the bluffs which form the terrace margin of that river valley. The next high land on the north side is Obidos, a bluff, 56 ft. above the river, backed by low hills. From Serpa, nearly opposite the river Madeira, to near the mouth of the Rio Negro, the banks are low, until approaching Manaos, they are rolling hills; but from the Negro, for 600 m. as far up as the village of Canaria, at the great bend of the Amazon, only very low land is found, resembling that at the mouth of the river. Vast areas of it are submerged athigh water, above which only the upper part of the trees of the sombre forests appear. At Canaria, the high land commences and continues as far as Tabatinga, and thence up stream.

On the south side, from the Tapajos to the river Madeira, the banks are usually low, although two or three hills break the general monotony. From the latter river, however, to the Ucayali, a distance of nearly 1500 m., the forested banks are just out of water, and are inundated long before the river attains its maximum flood-line. Thence to the Huallaga the elevation of the land is somewhat greater; but not until this river is passed, and the Pongo de Manseriche approached, does the swelling ground of the Andean foot-hills raise the country above flood-level.

The Amazon is not a continuous incline, but probably consists of long, level stretches connected by short inclined planes of extremely little fall, sufficient, however, owing to its great depth, to give the gigantic volume of water a continuous impulse towards the ocean. The lower Amazon presents every evidence of having once been an ocean gulf, the upper waters of which washed the cliffs near Obidos. Only about 10% of the water discharged by the mighty stream enters it below Obidos, very little of which is from the northern slope of the valley. The drainage area of the Amazon basin above Obidos is about 1,945,000 sq. m., and, below, only about 423,000 sq. m., or say 20%, exclusive of the 554,000 sq. m. of the Tocantins basin.

The width of the mouth of the monarch river is usually measured from Cabo do Norte to Punto Patijoca, a distance of 207 statute m.; but this includes the ocean outlet, 40 m. wide, of the Para river, which should be deducted, as this stream is only the lower reach of the Tocantins. It also includes the ocean frontage of Marajo, an island about the size of the kingdom of Denmark lying in the mouth of the Amazon.

Following the coast, a little to the north of Cabo do Norte, and for 100 m. along its Guiana margin up the Amazon, is a belt of half-submerged islands and shallow sandbanks. Here the tidal phenomenon called the bore, or Pororoca, occurs, where the soundings are not over 4 fathoms. It commences with a roar, constantly increasing, and advances at the rate of from 10 to 15 m. an hour, with a breaking wall of water from 5 to 12 ft. high. Under such conditions of warfare between the ocean and the river, it is not surprising that the former is rapidly eating away the coast and that the vast volume of silt carried by the Amazon finds it impossible to build up a delta.

The Amazon is not so much a river as it is a gigantic reservoir, extending from the sea to the base of the Andes, and, in the wet season, varying in width from 5 to 400 m. Special attention has already been called to the fourteen great streams which discharge into this reservoir, but it receives a multitude of secondary rivers, which in any other part of the wodd would also be termed great.

Population, trace, &c.

For 350 years after the discovery of the Amazon, by Pinzon, the Portuguese portion of its basin remained almost an undisturbed wilderness, occupied by Indian tribes whom the food quest had split into countless fragments. It is doubtful if its indigenous inhabitants ever exceeded one to every 5 sq. m. of territory, this being the maximum it could support under the existing conditions of the period in question, and taking into account Indian methods of life. A few settlements on the banks of the main river and some of its tributaries, either for trade with the Indians or for evangelizing purposes, had been founded by the Portuguese pioneers of European civilization. The total population of the Brazilian portion of the Amazon basin in 1850 was perhaps 300,000, of whom about two-thirds were white and slaves, the latter numbering about 25,000. The principal commercial city, Para, had from 10,000 to 12,000 inhabitants, including slaves. The town of Manaos, at the mouth of the Rio Negro, had from 1000 to 1500 population; but all the remaining villages, as far up as Tabatinga, on the Brazilian frontier of Peru, were wretched little groups of houses which appeared to have timidly effected a lodgment on the river bank, as if they feared to challenge the mysteries of the sombre and gigantic forests behind them. The value of the export and import trade of the whole valley in 1850 was but

On the 6th of September 1850 the emperor, Dom Pedro II., sanctioned a law authorizing steam navigation on the Amazon, and confided to an illustrious Brazilian, Barao Maua (Irineu Evangilista de Sousa), the task of carrying it into effect. He organized the "Compania de Navigacao e Commercio do Amazonas'' at Rio de Janeiro in 1852; and in the following year it commenced operations with three small steamers, the "Monarch,'' the "Marajo'' and "Rio Negro.'' At first the navigation was principally confined to the main river; and even in 1857 a modification of the government contract only obliged the company to a monthly service between Para and Manaos, with steamers of 200 tons cargo capacity, a second line to make six round voyages a year between Manaos and Tabatinga, and a third, two trips a month between Para and Cameta. The government paid the company a subvention of L. 3935 monthly. Thus the first impulse of modern progress was given to the dormant valley. The success of the venture called attention to the unoccupied field; a second company soon opened commerce on the Madeira, Purus and Negro; a third established a line between Para and Manaos; and a fourth found it profitable to navigate some of the smaller streams; while, in the interval, the Amazonas Company had largely increased its fine fleet. Meanwhile private individuals were building and running small steam craft of their own, not only upon the main river but upon many of its affluents. The government of Brazil, constantly pressed by the maritime powers and by the countries encircling the upper Amazon basin, decreed, on the 31st of July 1867, the opening of the Amazon to all flags; but limited this to certain defined points — Tabatinga, on the Amazon; Cameta, on the Tocantins; Santarem, on the Tapajos; Borba, on the Madeira; Manaos, on the Rio Negro; the decree to take effect on the 7th of September of the same year. Para, Manaos and Iquitos are now thriving commercial centres. The first direct foreign trade with Manaos was commenced about 1874.

The local trade of the river is carried on by the English successors to the Amazonas Company — the Amazon Steam Navigation Company. In addition to its excellent fleet there are numerous small river steamers, belonging to companies and firms engaged in the rubber trade, navigating the Negro, Madeira, Purfis and many other streams. The principal exports of the valley are india-rubber, cacao, Brazil nuts and a few other products of very minor importance. The finest quality of india-rubber comes from the Acre and Beni districts of Bolivia, especially from the valley of the Acre (or Aquiry) branch of the river Purus. Of the rubber production of the Amazon basin, the state of Para gives about 35%. The cacao tree is not cultivated, but grows wild in great abundance. There is but one railway in the whole valley; it is a short line from Para towards the coast. The cities of Para and Manaos have excellent tramways, many fine public buildings and private residences, gardens and public squares, all of which give evidence of artistic taste and great prosperity.

The number of inhabitants in the Brazilian Amazon basin (the states of Amazonas and Para) is purely a matter of rough estimate. There may be 500,000 or 600,000, or more; for the immigration during recent years from the other parts of Brazil has been large, due to the rubber excitement. The influx from the state of Ceara alone, from 1892 to 1899 inclusive, reached 98,348.

As Commander Todd, in his report to the United States government, says: "The crying need of the Amazon valley is food for the people.... At the small towns along the river it is nearly impossible to obtain beef, vegetables, or fruit of any sort, and the inhabitants depend largely upon river fish, mandioc, and canned goods for their subsistence.'' Although more than four centuries have passed since the discovery of the Amazon river, there are probably not 25 sq. m. of its basin under cultivation, excluding the limited and rudely cultivated areas among the mountains at its extreme headwaters, which are inaccessible to commerce. The extensive exports of the mighty valley are almost entirely derived from the products of the forest. (G. E. C.)

1 A furo is a natural canal — sometimes merely a deviation from the main channel, which it ultimately rejoins, sometimes a connexion across low flat country between two entirely separate streams.

2 Pongo is a corruption of the Quichua puncu and the Aymara ponco, meaning a door. The Pongo de Manseriche was first named Maranon, then Santiago, and later Manseric, afterwards Mansariche and Manseriche, owing to the great numbers of parrakeets found on the rocks there.

3 One of the most daring deeds of exoloration ever known in South America was done by the engineer A. Wertheman. He fitted out three rafts, in August 1870, and descended this whole series of rapids and cascades from the Rio Chinchipe to Borja.

4 A cano, like furo, is a kind of natural canal; it forms a lateral discharge for surplus water from a river.

5 Igapo is thus the name given to the recent alluvial tracts along the margins of rivers, submerged by moderate floods, whereas vargem is the term used for land between the levels of moderate and high floods, while for land above this the people use the term terra firma.

AMAZONAS, the extreme north-western and largest state of Brazil, bounded N. by Colombia and Venezuela, E. by the state of Para, S. by the state of Matto Grosso and Bolivia, and W. by Peru and Colombia. It embraces an area of 742,123 sq. m., wholly within the Amazon basin. A small part bordering the Venezuelan sierras is elevated and mountainous, but the greater part forms an immense alluvial plain, densely wooded, traversed by innumerable rivers, and subjected to extensive annual inundations. The climate is tropical and generally unfavourable to white settlement, the exceptions being the elevated localities on the Amazon exposed to the strong winds blowing up that river. The state is very sparsely populated; two-thirds of the inhabitants are Indians, forming small tribes, and subject only in small part to government control. The principal products are rubber, cacao and nuts; cattle are raised on the elevated plains of the north, while curing fish and collecting turtle eggs for their oil give occupation to many people on the rivers. Coffee, tobacco, rice and various fruits of superior quality are produced with ease, but agriculture is neglected and production is limited to domestic needs. The capital, Manaos, is the only city and port of general commercial importance in the state; other prominent towns are Serpa and Teffe on the Amazon, Borba and Crato on the Madeira, and Barcellos on the Rio Negro. Up to 1755 all the Portuguese territory on the Amazon formed part of the capitania of Para. The upper districts were then organized into a separate capitania, called S. Jose do Rio Negro, to facilitate administration. When Brazil became independent in 1822, Rio Negro was overlooked in the reorganization into provinces and reverted, notwithstanding the protests and an attempted revolution (1832) of the people, to a state of dependence upon Para. In 1850 autonomy was voted by the general assembly at Rio de Janeiro, and on the 1st of January 1852 the province of Amazonas was formally installed. In 1389 it became a federal state in the Brazilian republic.

AMAZONAS, a northern department of Peru, covering a mountainous district between the departments of Loreto and Cajamarca, with Ecuador on the N. The Maranon river forms the greater part of its W. boundary-line. Area, 13,943 sq. m.; pop. (1896) 70,676. The rainfall is abundant, and the soil of the heavily wooded valleys and lower mountain slopes is exceptionally fertile and productive. Its settlement and development is seriously impeded by the lack of transportation facilities. The capital, Chachapoyas, is a small town (pop. about 6000) situated on a tributary of the Maranon, 7600 ft. above sea-level. It is the seat of a bishopric, created in 1802, which covers the departments of Amazonas and Loreto, and one province of Libertad. It has an imposing cathedral and a university. The climate is equable and delightful, the mean temperature for the year being 62 deg. F.

AMAZONAS, a territory belonging to Venezuela, and occupying the extreme southern part of that republic, adjoining the Brazilian state of Amazonas. It lies partly within the drainage basin of the Orinoco and partly within that of the Rio Negro, an affluent of the Amazon. The territory is covered with dense forests and is filled with intricate watercourses, one of which, the Casiquiare, forms an open communication between the Orinoco and the Rio Negro and is navigable for large canoes. The capital of the territory is Maroa, situated on the Guainia river, an affluent of the Rio Negro.

AMAZONS, an ancient legendary nation of female warriors. They were said to have lived in Pontus near the shore of the

Euxine sea, where they formed an independent kingdom under the government of a queen, the capital being Themiscyra on the banks of the river Thermodon (Herodotus iv. 110-117). From this centre they made numerous warlike excursions — to Scythia, Thrace, the coasts of Asia Minor and the islands of the Aegean, even penetrating to Arabia, Syria and Egypt. They were supposed to have founded many towns, amongst them Smyrna, Ephesus, Sinope, Paphos. According to another account, they originally came to the Thermodon from the Palus Maeotis (Sea of Azov). No men were permitted to reside in their country; but once a year, in order to prevent their race from dying out, they visited the Gargareans, a neighbouring tribe. The male children who were the result of these visits were either put to death or sent back to their fathers; the female were kept and brought up by their mothers, and trained in agricultural pursuits, hunting, and the art of war (Strabo xi. p. 503). It is said that their right breast was cut off or burnt out, in order that they might be able to use the bow more freely; hence the ancient derivation of 'Amaxones from mafos, "without breast.'' But there is no indication of this practice in works of art, in which the Amazons are always represented with both breasts, although the right is frequently covered. Other suggested derivations are: a (intensive) and mafos, breast, "full-breasted''; a (privative) and masso, touch, "not touching men''; maza, a Circassian word said to signify "moon,'' has suggested their connexion with the worship of a moon- goddess, perhaps the Asiatic representative of Artemis.

The Amazons appear in connexion with several Greek legends. They invaded Lycia, but were defeated by Bellerophon, who was sent out against them by Iobates, the king of that country, in the hope that he might meet his death at their hands (Iliad, vi. 186). They attacked the Phrygians, who were assisted by Priam, then a young man (Iliad, iii. 189), although in his later years, towards the end of the Trojan war, his old opponents took his side against the Greeks under their queen Penthesileia, who was slain by Achilles (Quint. Smyr. i.; Justin ii. 4; Virgil, Aen. i. 490). One of the tasks imposed upon Heracles by Eurystheus was to obtain possession of the girdle of the Amazonian queen Hippolyte (Apollodorus ii. 5). He was accompanied by his friend Theseus, who carried off the princess Antiope, sister of Hippolyte, an incident which led to a retaliatory invasion of Attica, in which Antiope perished fighting by the side of Theseus. The Amazons are also said to have undertaken an expedition against the island of Leuke, at the mouth of the Danube, where the ashes of Achilles had been deposited by Thetis. The ghost of the dead hero appeared and so terrified the horses, that they threw and trampled upon the invaders, who were forced to retire. They are heard of in the time of Alexander the Great, when their queen Thalestris visited him and became a mother by him, and Pompey is said to have found them in the army of Mithradates.

The origin of the story of the Amazons has been the subject of much discussion. While some regard them as a purely mythical people, others assume an historical foundation for them. The deities worshipped by them were Ares (who is consistently assigned to them as a god of war, and as a god of Thracian and generally northern origin) and Artemis, not the usual Greek goddess of that name, but an Asiatic deity in some respects her equivalent. It is conjectured that the Amazons were originally the temple-servants and priestesses (hierodulae) of this goddess; and that the removal of the breast corresponded with the self-mutilation of the galli, or priests, of Rhea Cybele. Another theory is that, as the knowledge of geography extended, travellers brought back reports of tribes ruled entirely by women, who carried out the duties which elsewhere were regarded as peculiar to man, in whom alone the rights of nobility and inheritance were vested, and who had the supreme control of affairs. Hence arose the belief in the Amazons as a nation of female warriors, organized and governed entirely by women. According to J. Vurtheim (De Ajacis origine, 1907), the Amazons were of Greek origin: "all the Amazons were Dianas, as Diana herself was an Amazon.'' It has been suggested that the fact of the conquest of the Amazons being assigned to the two famous heroes of Greek mythology, Heracles and Theseus — who in the tasks assigned to them were generally opposed to monsters and beings impossible in themselves, but possible as illustrations of permanent danger and damage, — shows that they were mythical illustrations of the dangers which beset the Greeks on the coasts of Asia Minor; rather perhaps, it may be intended to represent the conflict between the Greek culture of the colonies on the Euxine and the barbarism of the native inhabitants.

In works of art, combats between Amazons and Greeks are placed on the same level as and often associated with combats of Greeks and centaurs. The belief in their existence, however, having been once accepted and introduced into the national poetry and art, it became necessary to surround them as far as possible with the appearance of not unnatural beings. Their occupation was hunting and war; their arms the bow, spear, axe, a half shield, nearly in the shape of a crescent, called pelta, and in early art a helmet, the model before the Greek mind having apparently been the goddess Athena. In later art they approach the model of Artemis, wearing a thin dress, girt high for speed; while on the later painted vases their dress is often peculiarly Persian — that is, close-fitting trousers and a high cap called the kidaris. They were usually on horseback but sometimes on foot. The battle between Theseus and the Amazons is a favourite subject on the friezes of temples (e.g. the reliefs from the frieze of the temple of Apollo at Bassae, now in the British Museum), vases and sarcophagus reliefs; at Athens it was represented on the shield of the statue of Athena Parthenos, on wall-paintings in the Theseum and in the Poikile Stoa. Many of the sculptors of antiquity, including Pheidias, Polyclitus, Cresilas and Phradmon, executed statues of Amazons; and there are many existing reproductions of these.

The history of Bohemia affords a parallel to the Greek Amazons. During the 8th century a large band of women, under a certain Vlasta, carried on war against the duke of Bohemia, and enslaved or put to death all men who fell into their hands. In the 16th century the Spanish explorer Orellana asserted that he had come into conflict with fighting women in South America on the river Maranon, which was named after them the Amazon (q.v.) or river of the Amazons, although others derive its name from the Indian amassona (boat-destroyer), applied to the tidal phenomenon known as the "bore.'' The existence of "Amazons'' (in the sense of fighting women) in the army of Dahomey in modern times is an undoubted fact, but they are said to have died out during the French protectorate. For notable cases of women who have become soldiers, reference may be made to Mary Anne Talbot and Hannah Snell.

AMAZON-STONE, or AMAZONITE, a green variety of microcline- felspar. The name is taken from that of the river Amazon, whence certain green stones were formedy obtained, but it is doubtful whether green felspar occurs in the Amazon district. The modern amazon-stone is a mineral of restricted occurrence. Formerly it was obtained almost exclusively from the neighbourhood of Miyask, in the Ilmen mountains, 50 m. S.W. of Chehabinsk, Russia, where it occurs in granitic rocks. Of late years, magnificent crystals have been obtained from Pike's Peak, Colorado, where it is found associated with smoky quartz, orthoclase and albite in a coarse granite or pegmatite. Some other localities in the United States yield amazon-stone, and it is also found in pegmatite in Madagascar. On account of its lively green colour, it is cut and polished to a limited extent as an ornamental stone. The colour has been attributed to the presence of copper, but as it is discharged by heat it is likely

to be due to some pigment of organic origin, and an organic salt of iron has been suggested. (See MICROCLINE.)

AMBARVALIA, an annual festival of the ancient Romans, occurring in May, usually on the 29th, the object of which was to secure the growing crops against harm of all kinds. The priests were the Arval Brothers (q.v.), who conducted the victims — ox, sheep and pig (suovetaurilia) — in procession with prayer to Ceres round the boundaries of the ager Romanus. As the extent of Roman land increased, this could no longer be done, and in the Acta of the Fratres, which date from Augustus, we do not find this procession mentioned (Henzen, Acta Fratrum Arvalium, 1874); but there is a good description of this or a similar rite in Virgil, Georg. i. 338 ff., and in Cato's work de Re Rustica (141) we have full details and the text of the prayers used by the Latin farmer in thus "lustrating'' his own land. In this last case the god invoked is Mars. The Christian festival which seems to have taken the place of these ceremonies is the Rogation or Gang week of the Roman Church. The perambulation or beatinc of bounds is probably a survival of the same type of rite.

See W. W. Fowler, Roman Festivals (1899), p. 124 ff. (W. W. F.*) AMBASSADOR (also EMBASSADOR, the form sometimes still used in America; from the Fr. ambassadeur, with which compare Ital. ambasciatore and Span. embajador, all variants of the Med. Lat. ambasciator, ambassiator, ambasator, &c., derived from Med. Lat. ambasciare or ambactiare, "to go on a mission, to do or say anything in another's name,'' from Lat. ambactus,1 a vassal or servant; see Du Cange, Glossarium, s.v. ambasciare), a public minister of the first rank, accredited and sent by the head of a sovereign state as his personal representative to negotiate with a foreign government, and to watch over the interests of his own nation abroad. The power thus conferred is defined in the credentials or letters of credence of which the ambassador is the bearer, and in the instructions under the sign-manual delivered to him. The credentials consist of a sealed letter addressed by the sovereign whom the ambassador represents to the sovereign to whom he is accredited, and they embody a general assurance that the sovereign by whom the ambassador is sent will confirm whatever is done by the ambassador in his name. In Great Britain letters of credence are under the royal sign-manual, and are not countersigned by a minister. Ambassadors are distinguished as ordinary and extraordinary, which implied originally the difference between a permanent mission and one appointed to conduct a particular negotiation. The style of ambassador extraordinary is, however, now often given to a minister accredited to a court for an indefinite time and implies a somewhat more dignified rank.

By the protocol of the 19th of March 1815, afterwards embodied in the treaty of Vienna (1815) and confirmed by an instrument signed by the five great powers at Aix-la-Chapelle on the 21st of November 1818, it was finally determined that "ambassadors and papal legates and nuncios alone have a representative character,'' i.e. in the most exalted and peculiar sense, as representing the person of the sovereign, or the head of a republic, as well as the state to which they belong. It follows that only states enjoying "royal honours,'' i.e. empires, kingdoms, grand duchies, the great republics (e.g. France, Switzerland, the United States of America) and the Holy See, have the right to send or to receive ambassadors. By custom it has moreover been established that, as a general rule, only the greater "royal states'' are represented by ambassadors, and then only when these are accredited to states esteemed, for one reason or another. to be of equal rank. Thus the promotion of the Japanese legations in Europe and the United States to the rank of embassies, and the corresponding change in the representation of the various powers at Tokio, marked in 1905 the definite recognition of Japan as a great power. To this rule the United States of America long remained an exception, and was content, in accordance with the tradition of republican simplicity, to be represented abroad only by ministers of the second rank. The subordinate position given to the representatives of so great a power, however, inevitably led to many inconveniences, and in 1893 an act of Congress empowered the president to accredit ambassadors to the great powers.

The distinction between an ambassador and ministers of the second rank is one rather of rank and dignity than of power or functions. His special immunities he shares with other diplomatic representatives of all classes. The peculiar privilege which he claims of free access to the sovereign has, in common practice, been reduced to the right of being received on presenting his credentials in public or private audience by the sovereign in person, it being obviously against public policy that a foreign representative should negotiate with the ruler otherwise than through his responsible ministers. In Great Britain the sovereign, when granting an audience to a foreign ambassador, is always attended by one or more ministers, and the same is usual in other states.

An ambassador, however, unless specially armed with plenary authority, cannot decide any questions beyond his instructions without reference to his government. Thus Lord Londonderry (Lord Stewart), who represented Great Britain at the conferences of Troppau in 1820 and Laibach in 1821, had not the same standing as the plenipotentiaries of the other powers present, and efforts were even made to exclude him from some of the more important discussions in consequence, not on the ground of inferior rank but of defective powers.

Socially, the position of an ambassador is one of great dignity. The pomp and magnificence which in earlier days characterized his progresses and his "entries'' are indeed no longer observed. He is received, however, by the sovereign to whom he is accredited with elaborate state, of which every detail is minutely regulated, and ranks, as representing his own sovereign, next to the princes of the blood in the court where he resides. The controversies that once raged as to the order of precedence of the various ambassadors accredited to any one court were settled by the treaties already mentioned, it being decided that they should rank in order of seniority according to the date of the presentation of their credentials. In Roman Catholic countries, however — as in France before the abrogation of the concordat, — the position of doyen (dean) of the diplomatic body is given by courtesy to the nuncio of the pope.

The special immunities and privileges enjoyed by ambassadors are dealt with in the articles EXTERRITORIALITY and DIPLOMACY. See also the latter for the history of the subject.

The most authoritative modern hand-book on the subject is Charles de Martens, Manuel diplomatlque (Paris, 1822; new ed., 1868). See also Henry Wheaton, Hist. of the Law of Nations (New York, 1845); L. Oppenheim, International Law (London, 1905); and the list of books attached to the article DIPLOMACY. (W. A. P.)

1 Ambactus is explained by Festus (Paulus Diaconus ex Festo, ed. C. O. Muller) as a Gallic word used by Ennius and meaning servus. Caesar (De Bello Gallico, vi. 15) says of the Gallic equites, "atque eorum ut quisque est genere copiisque amplissimus, plurimos circum se ambactos clientesque habent.'' Accepting the Celtic origin of the word, it has been connected with the Welsh amaeth, a tiller of the ground. A Teutonic origin has been suggested in the Old High Ger. ambaht, a retainer, which appears in a Scandinavian word amboht, bondwoman or maid, in the Ormulum (c. 1200).

AMRATO, or ASIENTO DE AMBATO, an inland town of Ecuador, capital of the province of Tunguragua, 80 m. S. of Quito by the highway, and near the northern foot of Chimborazo. Pop. (est.) 10,000. The town stands in a bowl-like depression, 8606 ft. above sea-level, surrounded by steep, sandy, barren mountains, and has an equable climate, which has been likened to a perpetual autumn. The immediate environs are very fertile and produce a great variety of fruits, including many of the temperate zone, but the surrounding country is arid and sterile, producing scanty crops of barley, Indian corn and pease. The cochineal insect is found on the cactus which grows in abundance in the vicinity, and the town is known throughout Ecuador for its manufacture of boots and shoes, and for a cordage made from cabuya, the fibre of the agave plant. Ambato was destroyed by an eruption of Cotopaxi in 1698, and has been badly damaged two or three times by earthquakes.

AMBATO is also the name of a range of mountains in northern Argentina, being a spur of the Sierra de Aconquija crossing the province of Catamarca from north to south.

AMBER, a ruined city of India, the ancient capital of Jaipur state in the Rajputana agency. The name of Amber is first mentioned by Ptolemy. It was founded by the Minas and was still flourishing in A.D. 967. In 1037 it was taken by the Rajputs, who held it till it was deserted. In 1728 it was supplanted by the modern city of Jaipur, from which it is 5 m. distant. The picturesque situation of Amber at the mouth of a rocky mountain gorge, in which nestles a lovely lake, has attracted the admiration of all travellers, including Jacquemont and Heber. It is now only remarkable for its architecture. The old palace begun by Man Sing in 1600 ranks second only to Gwalior. The chief building is the Diwan-i-Khas built by Mirza Raja. "No sooner,'' (it is related) "had Mirza completed the Diwan-i-Khas than it came to the ears of the emperor Jehangir that his vassal had surpassed him in magnificence, and that this last great work quite eclipsed all the marvels of the imperial city; the columns of red sandstone having been particularly noticed as sculptured with exquisite taste and elaborate detail. In a fit of jealousy the emperor commanded that this masterpiece should be thrown down, and sent commissioners to Amber charged with the execution of this order; whereupon Mirza, in order to save the structure, had the columns plastered over with stucco, so that the messengers from Agra should have to acknowledge to the emperor that the magnificence, which had been so much talked of, was after all pure invention. Since then his apathetic successors have neglected to bring to light this splendid work; and it is only by knocking off some of the plaster that one can get a glimpse of the sculptures, which are perfect as on the day they were carved.''

AMBER, a fossil resin much used for the manufacture of ornamental objects. The name comes from the Arab. anbar, probably through the Spanish, but this word referred originally to ambergris, which is an animal substance quite distinct from yellow amber. True amber has sometimes been called karabe, a word of oriental derivation signifying "that which attracts straw,'' in allusion to the power which amber possesses of acquiring an electric charge by friction. This property, first recorded by Thales of Miletus, suggested the word "electricity,'' from the Greek, elektron, a name applied, however, not only to amber but also to an alloy of gold and silver. By Latin writers amber is variously called electrum, sucinum (succinum), and glaesum or glesum. The Hebrew hashmal seems to have been amber.

Amber is not homogeneous in composition, but consists of several resinous bodies more or less soluble in alcohol, ether and chloroform, associated with an insoluble bituminous substance. The average composition of amber leads to the general formula C10H16O. Heated rather below 300 deg. C. amber suffers decomposition, yielding an "oil of amber,'' and leaving a black residue which is known as "amber colophony,'' or "amber pitch''; this forms, when dissolved in oil of turpentine or in linseed oil, "amber varnish'' or "amber lac.''

True amber yields on dry distillation succinic acid, the proportion varying from about 3 to 8%, and being greatest in the pale opaque or "bony'' varieties. The aromatic and irritating fumes emitted by burning amber are mainly due to this acid. True Baltic amber is distinguished by its yield of succinic acid, for many of the other fossil resins which are often termed amber contain either none of it, or only a very small proportion; hence the name "succinite'' proposed by Professor J. D. Dana, and now commonly used in scientific writings as a specific term for the real Prussian amber. Succinite has a hardness between 2 and 3, which is rather greater than that of many other fossil resins. Its specific gravity varies from 1.05 to 1.10.

The Baltic amber or succinite is found as irregular nodules in a marine glauconitic sand, known as "blue earth,'' occurring in the Lower Oligocene strata of Samland in East Prussia, where it is now systematically mined. It appears, however, to have been partly derived from yet earlier Tertiary deposits (Eocene); and it occurs also as a derivative mineral in later formations, such as the drift. Relics of an abundant flora occur in association with the amber, suggesting relations with the flora of Eastern . Asia and the southern part of North America. H. R. Goppert named the common amber-yielding pine of the Baltic forests Pinites succiniter, but as the wood, according to some authorities, does not seem to differ from that of the existing genus it has been also called Pinius succinifera. It is improbable, however, that the production of amber was limited to a single species; and indeed a large number of conifers belonging to different genera are represented in the amber-flora. The resin contains, in addition to the beautifully preserved plant-structures, numerous remains of insects, spiders, annelids, crustaceans and other small organisms which became enveloped while the exudation was fluid. In most cases the organic structure has disappeared, leaving only a cavity, with perhaps a trace of chitin. Even hair and feathers have occasionally been represented among the enclosures. Fragments of wood not infrequently occur, with the tissues well-preserved by impregnation with the resin; while leaves, flowers and fruits are occasionally found in marvellous perfection. Sometimes the amber retains the form of drops and stalactites, just as it exuded from the ducts and receptacles of the injured trees. The abnormal development of resin has been called "succinosis.'' Impurities are often present, especially when the resin dropped on to the ground, so that the material may be useless except for varnish-making, whence the impure amber is called firniss. Enclosures of pyrites may give a bluish colour to amber. The so-called "black amber'' is only a kind of jet. "Bony amber'' owes its cloudy opacity to minute bubbles in the interior of the resin.

Although amber is found along the shores of a large part of the Baltic and the North Sea, the great amber-producing country is the promontory of Samland. Pieces of amber torn from the sea-floor are cast up by the waves, and collected at ebb-tide. Sometimes the searchers wade into the sea, furnished with nets at the end of long poles, by means of which they drag in the sea-weed containing entangled masses of amber; or they dredge from boats in shallow water and rake up amber from between the boulders. Divers have been employed to collect amber from the deeper waters. Systematic dredging on a large scale was at one time carried on in the Kurisches Haff by Messrs Stantien and Becker, the great amber merchants of Konigsberg. At the present time extensive mining operations are conducted in quest of amber. The "pit amber'' was formerly dug in open works, but is now also worked by underground galleries. The nodules from the "blue earth'' have to be freed from matrix and divested of their opaque crust, which can be done in revolving barrels containing sand and water. The sea-worn amber has lost its crust, but has often acquired a dull rough surface by rolling in sand.

Amber is extensively used for beads and other trivial ornaments, and for cigar-holders and the mouth-pieces of pipes. It is regarded by the Turks as specially valuable, inasmuch as it is said to be incapable of transmitting infection as the pipe passes from mouth to mouth. The variety most valued in the East is the pale straw-coloured, slightly cloudy amber. Some of the best qualities are sent to Vienna for the manufacture of smoking appliances. In working amber, it is turned on the lathe and polished with whitening and water or with rotten stone and oil, the final lustre being given by friction with flannel. During the working much electricity is developed.
