In these lists the Aymara numerals, _one_, _two_ and _four_ are independent; _three_, _five_, _six_ and _ten_ are taken from the Kechua; and the remaining three are compound, _pa-callco_, being 2+5; _quimsa-callco_, 3+5; and _llalla-tunca_ meaning “less than ten.” _Callco_ is derived from the word for “foot,” the counting being with the toes. On the other hand, there is not a single numeral in the Puquina which can be derived from either Kechua or Aymara; and what is more remarkable, there is apparently not one which is compounded. It remains puzzling to me why the Puquina, which seems to have been spoken only by a few wretched villagers about Lake Titicaca, should have been classed by writers in the sixteenth century as one of the _lenguas generales_ of Peru. Not only does Ore refer to it by this term, but in one of the official _Relaciones Geograficas_ written in 1582, it is mentioned as “one of the three general languages of this kingdom.”[319] This would seem to indicate that at that period it had a wider extension than we can now trace. _4. The Yuncas._ The Yuncas occupied the hot valleys near the sea between south latitude 5° and 10°, their capital being in the vicinity of the present city of Truxillo. Their tongue belongs to an entirely different stock from the Kechua, and was not influenced by it. It still survives in a few sequestered valleys. The extreme difficulty of its phonetics aided to prevent its extension.[320] There is little doubt but that the Yuncas immigrated to their locality at some not very distant period before the conquest. According to their own traditions their ancestors journeyed down the coast in their canoes from a home to the north, until they reached the port of Truxillo.[321] Here they settled and in later years constructed the enormous palace known as the _Gran Chimu_, whose massive brick walls, spacious terraces, vast galleries and fronts decorated with bas-reliefs and rich frescoes, are still the wonder and admiration of travelers.[322] Near by, in the valley of Chicama and vicinity, they constructed capacious reservoirs and canals for irrigation which watered their well-tilled fields, and were so solidly constructed that some of them have been utilized by enterprising planters in this generation. Doubtless some of these were the work of the Incas after their conquest of this valley by the Inca Pachacutec, as is related by Garcilasso de la Vega,[323] but the fact that the Chimus were even before that date famed for their expertness in the working of metals and the fashioning of jewels and vases in silver and gold,[324] proves that they did not owe their culture to the instruction of the Quichuas.
