These islands in turn were peopled from the mainland to the east, as I have already shown, their earlier population having been Arawak. All the Island, Orinoco and Guiana Caribs can thus be traced back to the mainland of northern Venezuela. In this vicinity was spoken the Cumanagoto dialect, in the province of Cumana or New Andalusia. According to the early missionaries, it was current along the coast for more than a hundred leagues, extending into the province of Caracas and beyond. The tribes who spoke it were the Chaymas, the Cores, the Cumanas, the Quacas, the Parias, the Palenques, the Varrigones, and others.[375] Other dialects to the west are the Opone and Carare, specimens of which were obtained by Lengerke in the vicinity of Bucaramanga, province of Santander.[376] The sierra which divides the head-waters of the Caura from those of the Rio Branco and other streams flowing into the Rio Negro and Amazon, are peopled on both slopes by wandering tribes of the Carib stock. Near the sources of the Caura, Chaffanjon found the once formidable Guaharibos, now naked and wretched fugitives, fearing the white far more than they are feared by him.[377] On the southern slope, along the Rio Jauapery and neighboring streams, are bands of Crichanas, Ipurucotos (Purigotos), Macuchis, and Jauamerys (Waimiris), all speaking nearly related dialects of the Carib tongue. Dr. Barboza Rodrigues has given a touching picture of their recent struggles with the whites of the adjacent settlements, and the miserable condition to which they are reduced. We owe to the same sympathetic naturalist an interesting description of their customs and language.[378] The hill tribes of French Guiana are known as Roucouyennes, from the _roucou_, a vegetable coloring matter with which they paint their skins. They exhale a peculiar odor like that of new leather, probably from the action of the tannin in the roucou on the skin. Naturally they are light in color, and at birth almost white.[379] Marriages of father and daughter, or brother and sister, are not rare among them.[380] A connecting link between these Caribs of Guiana and the Bakairis of the south is supplied by the Apiacas of the Rio Tocantins, who speak a pure dialect of the stock, midway in character between those of the two extremes named.[381] The Arubas, who occupied the island of that name off the coast of Venezuela, and whose mixed descendants now speak the Papamiento jargon, are no doubt correctly assigned to this stock by M. Pinart. They were skillful potters, and buried their dead in large urns. The numerous polychromatic petroglyphs they have left and their peculiar character are especially noteworthy.[382] Sir Robert H. Schomburgk classifies the Carib stock in Guiana as follows, giving a short specimen of each dialect, which differ, he says, among themselves about as much as French and Italian.[383] CARIB SUB-STOCK IN GUIANA.
