These industries include cultivation of corn and manioc, the manufacture of fibres from the _moriche_-palm for cloth, of simple earthenware, often decorated with hieroglyphics in colour, of pigments for this and for painting their bodies in wartime. Their arrows are often poisoned with _curare_, the concentrated and congealed sap of the _mavacure_ creeper, sometimes also with the extracted juice of the poisonous manioc. From the pith of the moriche-palm they obtain a kind of sago-meal, and this, with maize flour, bitter and sweet manioc or cassava-bread, and fish-paste or meat from their hunting expeditions, forms their staple diet. Their canoes are of bark or dug out of the solid trunk with the aid of stone or flint hatchets or fire. For hunting and war they had in early times good bows and arrows, spears of hard, heavy wood, shields of plaited creepers covered with hides of manati, tapir, or jaguar. Nor were they without musical (?) instruments, of which the _maracas_ or rattles of small dried calabashes are used all over Venezuela in the country districts to-day. Their religious beliefs appear to be, generally speaking, those of the Goajiros without the sun-worship, and birth, marriage, and death customs are much alike amongst all the tribes, whether Carib or no. The only difference here is that, in place of the usual marriage by consent without any religious ceremony, at the time of their conquest of the mainland, they adopted in part a marriage by capture, which has otherwise never been their custom. The principal tribes of the aborigines of Guayana are thus enumerated, with their distribution and general characteristics, by Tavera Acosta, the spelling of the names being changed in some cases. (1) The Warraus or Guaraunos (see note, p. 122) of the Delta; dull, unintelligent, and dirty. (2) Arawaks, south of the Delta; intelligent, gentle, and exceptionally cleanly. (3) Banibas, a branch of the Quichua nation living on the Guainia or Rio Negro and Atabapo; intelligent, gentle, and of a sedentary mode of life, excellent boatmen and hammock-makers. (4) Guahibos or Uajibas, on the Vichada; dirty. (5) Barias, on the Baria, Casiquiare, and Rio Negro; good workers and boatmen. (6) Yaviteras, at Yavita; like the Barias. (7) Piaroas, including the Maipures and Atures; living on the Sipapo, Cataniapo and Mataveni; timid and agricultural. (8) Puinabi or Guaipunavi, on the Inirida; intelligent, but fierce. (9) Caruzana or Marapizanos; on the Guainia, and neighbouring rivers, cultivators of manioc. (10) Wareca or Guareca, at San Miguel and Baltazar; intelligent and industrious. (11) Piapocos and Salibas, on the Guaviare, &c.; agricultural. (12) Guaharibos, round the head-waters of the Orinoco; savage.
