Little is known of their domestic customs and superstitions. The men have each but one wife; the dead are buried in the sandy beaches; and they are not known to have any pagés. A few families only live together, in little moveable villages, to each of which there is a Tushaúa. They have, at times, dances and festivals, when they make intoxicating drinks from wild fruits, and amuse themselves with rude musical instruments, formed of reeds and bones. They do not use salt, but prefer payment in fish-hooks, knives, beads, and farinha, for the salsaparilha and turtle-oil which they sell to the traders.
May not the curious disease, to which they are so subject, be produced by their habit of constantly sleeping naked on the sand, instead of in the comfortable, airy, and cleanly hammock, so universally used by almost every other tribe of Indians in this part of South America?
The Catauixis, though in the immediate neighbourhood of the last, are very different. They have permanent houses, cultivate mandiocca, sleep in hammocks, and are clear-skinned. They go naked like the last, but do not bore holes in their nose and lips; they wear a ring of twisted hair on their arms and legs. They use bows, arrows, and gravatánas, and make the ervadúra, or ururí poison. Their canoes are made of the bark of a tree, taken off entire. They eat principally forest game, tapirs, monkeys, and large birds; they are however cannibals, killing and eating any Indians of other tribes they can procure, and they preserve the meat, smoked and dried. Senhor Domingos, a Portuguese trader up the river Purús, informed me that he once met a party of them, who felt his belly and ribs, as a butcher would handle a sheep, and talked much to each other, apparently intimating that he was fat, and would be excellent eating.
Of the Jamamarís we have no authentic information, but that they much resemble the last in their manners and customs, and in their appearance.
The Jubirís are equally unknown; they however most resemble the Purupurús in their habits and mode of life, and, like them, have their bodies spotted and mottled, though not to such a great extent.
In the country between the Tapajóz and the Madeira, among the labyrinth of lakes and channels of the great island of the Tupinambarános, reside the Mundrucús, the most warlike Indians of the Amazon. These are, I believe, the only perfectly tattooed nation in South America: the markings are extended all over the body; they are produced by pricking with the spines of the pupunha palm, and rubbing in the soot from burning pitch to produce the indelible bluish tinge.
They make their houses with mud walls, in regular villages. In each village they have a large building which serves as a kind of barrack, or fortress, where all the men sleep at night, armed with their bows and arrows, ready in case of alarm: this house is surrounded within with dried heads of their enemies: these heads they smoke and dry, so as to preserve all the features and the hair most perfectly. They make war every year with an adjoining tribe, the Parentintins, taking the women and children for slaves, and preserving the heads of the men. They make good canoes and hammocks. They live principally on forest-game, and are very agricultural, making quantities of farinha and growing many fruits. The men have each one wife, and each village its chief. Cravo or wild nutmegs, and farinha, are the principal articles of their trade; and they receive in exchange cotton cloth, iron goods, salt, beads, etc.
In the Rio Branco are numerous tribes, and some of them are said to practise circumcision.
Others, near the sources of the Tapajóz, make the girls undergo the same cruel initiation as has been already described as common among the Uaupés and Isánna Indians.
On the north banks of the Rio Negro are many uncivilized tribes, very little known.
