Whether we should include in this stock the Macas, who dwell on the eastern slope of the Andes a few degrees south of the equator, is not clear, as I have found no vocabularies. Velasco refers to them as a part of the Scyra stock, and they are in the Kechua region. Mr. Buckley, who visited them a few years ago, describes them as divided into small tribes, constantly at war with each other. Their weapons are spears and blow-pipes with poisoned arrows. Hunting is their principal business, but they also raise some maize, yucca and tobacco. Polygamy prevails along with the patriarchal system, the son inheriting the property of his father. Some rude pottery is manufactured, and their huts of palm leaves are neatly constructed. Like the Jivaros, they prepare the heads of the dead, and sometimes a man will kill one of his wives if he takes a fancy that her head would look particularly ornamental thus preserved.[292] The southern limit of the Kechua tongue, before the Spanish conquest, has been variously put by different writers; but I think we can safely adopt Coquimbo, in south latitude 30°, as practically the boundary of the stock. We are informed that in 1593 the priests addressed their congregations in Kechua at this place,[293] and in the same generation the missionary Valdivia names it as the northern limit of the Araucanian.[294] Doubtless, however, it was spoken by outlying colonies as far south as the river Maule, in south latitude 35°, which other writers assign as the limit of the conquests of the Incas. Cieza de Leon and other early Spanish writers frequently refer to the general physical sameness of the Peruvian tribes. They found all of them somewhat undersized, brown in color, beardless, and of but moderate muscular force.
