Perhaps even a greater extension has been given by the German explorers to the Arawakan family, which, like the Cariban, was hitherto supposed to be mainly confined to the region north of the Amazons, but is now known to range as far south as the Upper Paraguay, about 20° S. lat. (Layana, Kwana, etc.), east to the Amazons estuary (Aruan), and north-west to the Goajira peninsula. To this great family—which von den Steinen proposes to call Nu-Aruak from the pronominal prefix nu = I, common to most of the tribes—belong also the Maypures of the Orinoco; the Atarais and Vapisiana of British Guiana; the Manao of the Rio Negro; the Yumana; the Paumari and Ipurina of the Ipuri basin; the Moxo of the Upper Mamoré, and the Mehinaku and Kustenau of the Upper Xingu.

Physically the Arawaks differ from the Caribs scarcely, if at all, more than their Amazonian and Guiana sections differ from each other. In fact, but for their radically distinct speech it would be impossible to constitute these two ethnical divisions, which are admittedly based on linguistic grounds. But while the Caribs had their cradle in Central Brazil and migrated northwards, the Arawaks would appear to have originated in eastern Bolivia, and spread thence east, north-east and south-east along the Amazons and Orinoco and into the Paraguay basin[950].

The Gesan Family.

Our third great Brazilian division, the Gesan family, takes its name from the syllable ges which, like the Araucan che, forms the final element of several tribal names in East Brazil. Of this the most characteristic are the Aimores of the Serra dos Aimores coast range, who are better known as Botocudo, and it was to the kindred tribes of the province of Goyaz that the arbitrary collective name of "Ges" was first applied by Martius. A better general designation would perhaps have been Tapuya, "Strangers," "Enemies," a term by which the Tupi people called all other natives of that region who were not of their race or speech, or rather who were not "Tupi," that is, "Allies" or "Associates." Tapuya had been adopted somewhat in this sense by the early Portuguese writers, who however applied it rather loosely not only to the Aimores, but also to a large number of kindred and other tribes as far north as the Amazons estuary.

To the same connection belong several groups in Goyaz already described by Milliet and Martius, and more recently visited by Ehrenreich, von den Steinen and Krause. Such are the Kayapo or Suya, a large nation with several divisions between the Araguaya and Xingu rivers; and the Akua, better known as Cherentes, about the upper course of the Tocantins. Isolated Tapuyan tribes, such as the Kamés or Kaingangs, wrongly called "Coroados," and the Chogleng of Santa Catharina and Rio Grand do Sul, are scattered over the southern provinces of Brazil.

The Tapuya would thus appear to have formerly occupied the whole of East Brazil from the Amazons to the Plate River for an unknown distance inland. Here they must be regarded as the true aborigines, who were in remote times already encroached upon, and broken into isolated fragments, by tribes of the Tupi-Guarani stock spreading from the interior seawards[951].

The Botocudo.

But in their physical characters and extremely low cultural state, or rather the almost total absence of anything that can be called "culture," the Tapuya are the nearest representatives and probably the direct descendants of the primitive race, whose osseous remains have been found in the Lagoa Santa caves, and the Santa Catharina shell-mounds (sambaqui). On anatomic grounds the Botocudo are allied both to the Lagoa Santa fossil man and to the sambaqui race by J. R. Peixoto, who describes the skull as marked by prominent glabella and superciliary arches, keel or roof-shaped vault, vertical lateral walls, simple sutures, receding brow, deeply depressed nasal root, high prognathism, massive lower jaw, and long head (index 73.30) with cranial capacity 1480 c.c. for men, and 1212 for women[952]. It is also noteworthy that some of the Botocudo[953] call themselves Nacnanuk, Nac-poruc, "Sons of the Soil," and they have no traditions of ever having migrated from any other land. All their implements—spears, bow and arrows, mortars, water-vessels, bags—are of wood or vegetable fibre, so that they may be said not to have yet reached even the stone age. They are not, however, in the promiscuous state, as has been asserted, for the unions, though temporary, are jealously guarded while they last, and, as amongst the Fuegians whom they resemble in so many respects, the women are constantly subject to the most barbarous treatment, beaten with clubs or hacked about with bamboo knives. One of those in Ribeiro's party, who visited London in 1883, had her arms, legs, and whole body covered with scars and gashes inflicted during momentary fits of brutal rage by her ephemeral partner. Their dwellings are mere branches stuck in the ground, bound together with bast, and though seldom over 4 ft. in height accommodating two or more families. The Botocudo are pure nomads, roaming naked in the woods in quest of the roots, berries, honey, frogs, snakes, grubs, man, and other larger game which form their diet, and are eaten raw or else cooked in huge bamboo canes. Formerly they had no hammocks, but slept without any covering, either on the ground strewn with bast, or in the ashes of the fire kindled for the evening meal. About their cannibalism, which has been doubted, there is really no question. They wore the teeth of those they had eaten strung together as necklaces, and ate not only the foe slain in battle, but members of kindred tribes, all but the heads, which were stuck as trophies on stakes and used as butts for the practice of archery.

At the graves of the dead, fires are kept up for some time to scare away the bad spirits, from which custom the Botocudo might be credited with some notions concerning the supernatural. All good influences are attributed by them to the "day-fire" (sun), all bad things to the "night-fire" (moon), which causes the thunderstorm, and is supposed itself at times to fall on the earth, crushing the hill-tops, flooding the plains and destroying multitudes of people. During storms and eclipses arrows are shot up to scare away the demons or devouring dragons, as amongst so many Indo-Chinese peoples. But beyond this there is no conception of a supreme being, or creative force, the terms yanchong, tapan, said to mean "God," standing merely for spirit, demon, thunder, or at most the thunder god.
