The Quichua-Aymara
This people consisted of two groups, the Quichua and Aymara, so called from the two kindred tongues spoken by each respectively. These possess a common grammatical structure, and a great number of words are common to both. They are in reality varying forms of one speech. From the valley of Titicaca the Aymara spread from the source of the Amazon river to the higher parts of the Andes range, so that in course of time they exhibited those qualities which stamp the mountaineer in every age and clime. The Quichua, on the other hand, occupied the warm valleys beyond the river Apurimac, to the north-west of the Aymara-speaking people—a tract equal to the central portion of the modern republic of Peru. The name “Quichua” implies a warm valley or sphere, in contradistinction to the “Yunca,” or tropical districts of the coast and lowlands.
