These southern nations make skeletons of their dead, as is done likewise by the native tribes on the Orinoco; but it is singular that this practice does not prevail among the intermediate tribes, that inhabit between the Maranon and Rio Plata. On such occasions, one of the most distinguished women of the tribe performs the ceremony of dissection. The entrails are burnt, and the bones, after the flesh has been cut off as clean as possible, are buried till the remaining fibres decay. This is the custom of the Molnuches and Pampas, but the Serranos place the bones on a high frame-work of canes or twigs to bleach in the sun and rain. While the dissector is at work on the skeleton, the Indians walk incessantly round the tent, having their faces blackened with soot, dressed in long skin mantles, singing in a mournful voice, and striking the ground with their long spears, to drive away the evil spirits. Some go to condole with the widow and relations of the dead, if these are wealthy enough to reward them for their mourning with bells, beads, and other trinkets; as their customary condolence is not of a nature to be offered gratuitously, for they prick their arms and legs with thorns, and feel pain at least if not sorrow. The horses belonging to the deceased are slain, that he may ride upon them in the alhue-mapu, or country of the dead; but a few of these are reserved to carry his bones to the place of sepulchre, which is done in grand ceremony within a year after his death. They are then packed up in a hide, and laid on the favourite horse of the deceased, which is adorned with mantles, feathers, and other ornaments and trinkets. In this manner the cavalcade moves to the family burial-place, often three hundred leagues from the place of death, so wide and distant are their wanderings in the boundless plains to the south of the Rio Plata.

The Moluches and Pampas bury in large square pits about six feet deep, the bones being first accurately put into their proper places and tied together, clothed in the best robes of the deceased, and ornamented with beads and feathers, all of which are cleaned or changed once a-year. These skeletons are placed in a sitting posture in a row, with all the weapons and other valuables belong to each laid beside him. The pit is then covered over with beams or twigs, on which the earth is spread. An old matron of each tribe is appointed to the care of these sepulchres, who has to open them once a-year, to clean and new clothe the skeletons, for which service she is held in great estimation. The bodies of the slain horses are placed round the sepulchre, raised on their feet and supported by stakes. These sepulchres are generally at a small distance from the ordinary habitations of the tribe. Every year they pour upon them some bowls of their first made chica, or fermented liquor, and drink to the happiness of the dead. The Tehuelhets and other southern tribes carry their dead to a great distance from their ordinary dwellings, into the desert near the sea-coast, where they arrange them above ground surrounded by their horses. It is probable that only those Indians who carry their dead to considerable distances reduce them to skeletons, from the following circumstance. In the voyage of discovery made in 1746 in the St Antonio from Buenos Ayres to the Straits of Magellan, the Jesuits who accompanied the expedition found one of these tents or houses of the dead. On one side six banners of cloth of various colours, each about half a yard square, were set up on high poles fixed in the ground; and on the other side five dead horses stuffed with straw and supported, on stakes. Within the house, there were two ponchos extended, on which lay the bodies of two men and a woman, having the flesh and hair still remaining. On the top of the house was another poncho, rolled up and tied with a coloured woolen band, in which a pole was fixed, from which eight tassels of wool were suspended.

Widows are obliged to observe a long and rigorous mourning. During a whole year after the death of their husbands, they must keep themselves secluded in the tents, never going out except on the most necessary avocations, and having no communication with any one. In all this time, they must abstain from eating the flesh of horses, cows, ostriches, or guanacos, must never wash their faces which are constantly smeared with soot, and any breach of chastity during this year of mourning is punished with the death of both parties by the relations of the husband.

The office of ya, or chief, is hereditary, and all the sons of a ya may be chiefs likewise if they can procure followers; but the dignity is of so little consequence that nobody almost covets the office. To him belongs the office of protecting his followers, of composing differences, and of delivering up any offender who is to be capitally punished; in all which, cases his will is the sole law. These petty despots are prone to bribery, and will readily sacrifice their vassals and even their kindred for a good bribe. They are esteemed in proportion to their eloquence, and any chief who is not himself eloquent employs an orator to harangue the tribe in his place. When two or more tribes form an alliance against a common enemy, they elect an apo, or commander-in-chief, from the ablest or most celebrated of the yas, or hereditary chiefs. But this office, though nominally elective, has been long hereditary among the southern tribes in the family of Cangapol. The hereditary chiefs, named yas, elmens, or ulmens, have no power to take any thing from their vassals, neither can they oblige them to perform any work without payment. On the contrary they must treat them kindly and relieve their wants, or their vassals will put themselves under the protection of a more generous chief. Many of them therefore wave the privilege of their birth, and decline having any vassals, because they are expensive appendages, which yield little profit. But every-one must attach themselves to some chief, or they would undoubtedly be put to death or reduced to slavery.

Every man buys his wife from her relations, with or without her consent, and then takes possession of her as his property. But if the woman happens to have fixed her affections on another, she contrives to wear out the patience of her purchaser, who either turns her away or sells her to the man of her choice, but seldom uses her ill. Widows, and orphan girls are at their own disposal. The yas or ulmens have generally two or three wives; and even the common people may have as many as they please, but wives are dear and they are generally contented with one. The lives of the women are one continued series of labour. They fetch wood and water; dress the victuals; make, mend, and clean the tents; cure the skins; make them into mantles; spin and manufacture ponchos; pack up every thing for a journey, even the tent poles; load, unload, and arrange the baggage; straiten the girths of the horses; carry the lance before their husbands; and at the end of the journey set up the tents. Sickness or even the most advanced pregnancy give no relief from these labours, and it would be reckoned ignominious in the husbands to give them any assistance. The women of noble families may have slaves to relieve them of these labours; but when in want of these, must undergo the same fatigues as the rest. Yet the tribes of the southern extremity of America are not brutal to their women like those in the north, and the marriages only endure during pleasure, though those who have children seldom separate. The husband invariably protects his wife, even when in the wrong; and if detected in any criminal intercourse, all his anger falls upon the paramour, who is cruelly beaten, unless he can atone for the injury by payment. Their jugglers sometimes persuade them to send their wives into the woods, to prostitute themselves to the first person they meet, which is obviously a device for consoling themselves from the celibacy to which they are condemned. The husbands readily obey these directions; but there are women in whom native modesty overpowers superstition, who refuse obedience to their husbands on such occasions, and bid defiance to the wizard.
