The indigenous population comprised two groups: the Tehuelches, or Patagonians proper, men of tall stature, and the Araucans, the Ranqueles, the Pehuenches and the Pampas. There was no fixed geographical limit between them. The Tehuelches lived in southern Patagonia; but the Araucans advanced eastward as far as the Pampas region and southward beyond the Chubut. The Indian population of the valley of the Genua and the Sanguerr, south of the colony of San Martin, comprised in 1880,[58] and still comprises,[59] a mixture of Araucans and Tehuelches. The Araucans were acquainted with agriculture, but, once they had tamed the horse, they became mainly a pastoral and hunting people, like the Tehuelches. [58] Carlos M. Moyano, "Informe sobre un viaje a traves de la Patagonia," _Bol. Instit. Geog. Argent._, ii. 1881, pp. 1-35. [59] W. Vallentin, _Chubut_ (Berlin, 1906). In so far as they were hunters, the Indians of Patagonia were nomadic. The taming of the horse only made it easier for them to shift from place to place, and gave them a greater range. Their nomadism has too often been regarded as an aimless wandering. They had laws, settled by the physical conditions; and we can gather a few of these. They kept away from the coastal districts except in winter; that is the season when the rains provide water-courses there. It has been observed that names of Indian origin are lacking on the coast of Patagonia. The Spanish navigators who landed there during the summer found the country deserted and the camps abandoned. On the other hand, the share of the Indians in giving names is very considerable in the interior, as far as the foot of the Andes. During the summer the Indians approached the mountains, where they found good hunting grounds. In particular they chased the young guanacos in the breeding season, December and January. Popper has indicated similar migrations amongst the Onas of Patagonia; they approach the coast in winter, and leave it in summer, to hunt in the interior.[60] The district of Lake Nahuel Huapi and Collon Cura had some attraction from afar. The forest of araucarias produced seeds (_pinones_) which the Indians went to gather; and they also liked the wild apples which ripened on the former estates of the old Jesuit missions. The clusters of bamboo on the Cordillera provided the lances of the Aucas and Tehuelches. [60] J. Popper, "Exploracion de la Tierra del Fuego," _Bol. Instit. Geog. Argent._, viii. 1887, pp. 74-93.
