The Huilliches possess the country from Valdivia to the Straits of Magellan. They are divided into four tribes, who are improperly classed together as one nation, since three of them are evidently of a different race from the fourth. That branch which reaches to the sea of Chiloe and beyond the lake of Nahuelhuaupi speaks the general language of Chili, differing only from the Pehuenches and Picunches in pronunciation. The others speak a mixed language, composed of the Moluche and Tehuel tongue, which latter is the Patagon; and these tribes, from their great stature, are evidently of Patagonian origin. Collectively these three tribes are called the Vuta-Huilliches, or great southern-people; separately they are named Chonos, Poy-yes, and Key-yes. The Chonos inhabit the archipelago of Chili, and the adjoining shores of the continent. The Poy-yes or Peyes possess the coast from lat. 48° to something more than 51° S. The Key-yes or Keyes extend from thence to the Straits of Magellan. The Moluches maintain some flocks of sheep, principally for the sake of their wool, and cultivate a small quantity of corn.

The Puelches or eastern people, which name they receive from the natives of Chili, are bounded on the west by the Moluches, on the south by the Straits of Magellan, on the east by the sea, and on the north by the Spaniards. They are subdivided into four tribes, the Taluhets, Diuihets, Chechehets, and Tehuelhets. The first of these or Taluhets, are a wandering race who prowl over the country, from the eastern side of the first desaguadero as far as the lakes of Guanacache in the jurisdiction of San Juan and San Luiz de la Punta. Some of them are also to be found in the jurisdiction of Cordova, on the rivers Segundo Terzo and Quarto. When the Jesuits were expelled from the missions, this tribe could scarcely raise two hundred fighting men, and even in conjunction with all their allies not above five hundred. The second of these tribes, called the Diuihets, is, also a wandering race, which borders westwardly on the Pehuenches, between the latitudes of 35° and 38° S. They extend along the rivers Sanguel Colorado and Hueyque, and nearly to the Casuhati on the east. This nation and that of the Taluhets are collectively called Pampas by the Spaniards, whose settlements in Tacuman and on the southern shore of the La Plata they have always infested, and sometimes even endangered. The third tribe of the Puelches is named the Chechehets, or eastern-people. The country which they chiefly frequent is situated between the rivers Hueyque and the first desaguadero or Rio Colorado, and from thence to the second desaguadero or Rio Negro. They are a tall and stout wandering race resembling the Patagonians, but speak a quite different language. Their dispositions are friendly and inoffensive, but they are a bold and active enemy when provoked. They are now reduced to a small number by the ravages of the small-pox. The fourth race, called the Tehuelhets, or in their own language the Tehuel-kunnees or southern-men, are the real Patagonians. These are again subdivided into many tribes, all of which and the Chechehets also are called Serranos or mountaineers by the Spaniards. The Leuvuches, who seem to be the head tribe of all the Serranos, live on the Rio Negro. They speak the same language with the Chechehets, but with a small mixture of the Tehuel. This tribe used to keep on good terms with the Spaniards, that they might hunt in security in the pampas or immense plains of Buenos Ayres. About the year 1740, however, they were provoked to war by a most wanton and treacherous attack, and Buenos Ayres would in all probability have been destroyed, had not these injured people been appeased by the Jesuit missionaries. The Tehuelhets are more numerous than all the other tribes of these parts together, and are the perpetual enemies of the Moluches who are so terrible to the Spaniards, whom they would have long since destroyed if they had been equally well supplied with horses.

To the south of these are the Chulilau-Kunnees, and the Sehuan-Kunnees, who are the most southerly of the equestrian tribes. The country beyond them, all the way to the Straits of Magellan, is possessed by the last of the Tehuel tribes, called Yacana-Kunnees or foot-people, as they have no horses. These are an inoffensive race, who are very swift runners, and subsist mostly on fish. The other Tehuelhets and the Huilliches sometimes attack this tribe for the purpose of making slaves of the prisoners. The ordinary stature of all the Tehuel tribes is from six to seven feet. None of the Puelches either keep sheep or cultivate the ground, but depend altogether on hunting, for which purpose they keep a great number of dogs.

The belief in an infinite number of spirits, good and evil, is common to all the native tribes south of the Rio Plata. From the north of that river to the Orinoco a different language prevails, accompanied by a different form of superstition The Puelches do not appear to acknowledge any of those numerous spirits as supreme over the rest. The Taluhets and Diuihets call a good spirit Soychu, or he who presides in the land of strong drink. The Tehuelhets call an evil spirit Atskanna Kanatz, the other Puelches denominate the same being Valichu. Huecuvu must be another name for the evil spirit; as the Chechehets give the name of Huecuvu-mapu or the devils-country to a great sandy desert, into which they never venture lest they should be overwhelmed.

Among the northern Indians, each cast or small tribe is distinguished by the name of some animal; as the tribe of the tyger, the lion, the guanaco, the ostrich, and the like. They believe that each tribe had its own particular creator, who resided in some huge cavern under a lake or bill, to which all of that tribe will go after death, to enjoy the felicity of eternal inebriation. These good creative spirits, according to their opinion, having first created the world, made the different races of men and animals, each in their respective cave. To the Indians, they gave the spear, the bow and arrow, and the lague or ball and thong: to the Spaniards fire arms. Animals they allege were likewise created in these subterranean abodes of the spirits, such as were nimblest coming first out. When bulls and cows were coming out last of all, the Indians were frightened at the sight of their horns, and stopped up the mouth of their cavern; but the Spaniards were wiser and let them out. Thus they explain the reason why they had no cattle till after the coming of the Spaniards. In. their opinion, all the animals who have been created in these hidden caverns have not yet emerged. They attribute all the misfortunes or diseases which happen to men or animals to the agency of the evil spirits, who are continually wandering about the world in search of mischief. Their priests or jugglers rather, are each supposed to be attended by two familiar evil spirits, to whom the souls of these jugglers are associated after death, and with whom they go about to do mischief. The jugglers are of both sexes; but it seems as if it were thought an occupation beneath the dignity of a man, as the male wizards are compelled to dress like women and are not permitted to marry. The female jugglers are under no such restriction. They are generally chosen while children to be initiated in the mysteries of this profession, from among those who are most effeminate, and such as happen to be subject to epilepsy or St Vitus' dance are considered as especially marked out for the service of the jugglers. It is a very dangerous profession, as these jugglers are frequently put to death when any calamity happens to befal either the chiefs or the people.

No ceremonies are performed in honour of the good spirits. That which is addressed to the evil ones is performed in the following manner. The assistants assemble in the hut or tent of the wizard, who is concealed in a corner of the tent, where he has a drum, one or two round calabashes with a few small sea shells in them to make a noise, like the maraca or rattle of the Brazilian sorcerers, and some square bags of painted hide in which he keeps his spells. He begins the ceremony by making a strange noise with his drum and rattle, after which he feigns to fall into a fit, which is supposed to be occasioned by a struggle with the evil spirit who then enters into him. During this fit, he keeps his eye-lids lifted up, distorts his features, foams at the mouth, seems to dislocate his joints, and after many violent and unnatural motions remains stiff and motionless, like a person in a fit of epilepsy. After some time he comes to himself, as if having gained the victory over the evil spirit. He next causes a faint shrill mournful voice to be heard within his tabernacle, as of the evil spirit, who is supposed to acknowledge himself vanquished; after which the wizard, from a kind of tripod, answers all questions that are put to him. It is of little consequence whether these answers turn out true or false, as on all sinister events the fault is laid on the spirit. On these conjuring occasions, the juggler is well paid by those who consult the destinies.
