Fishing was an important industry and on the coast regions it ranked next to agriculture. They had a kind of raft, balsa, made of bundles of reeds or poles fastened together and they used nets, harpoons made of copper or tipped with copper, and hooks of bone or copper. Fowling was carried on by means of nets and quite largely engaged in especially along the coast where there were great numbers of birds. Game was plentiful in the mountainous regions and often great drives were made, sometimes as many as fifty or sixty thousand people took part in one and in which thirty thousand head of game might have been taken. They used dogs in hunting, having had at least two varieties of hunting dogs. Beasts of prey, such as pumas, bears, foxes, and wild-cats were killed. The real purpose of the hunt, though, was to capture the huanaco and vicuña, from which the wool was cut and then the greater part of them, the females and best males, were turned loose to let the wool grow for another year, some being kept for food. Besides these wild animals, they kept great flocks of llamas and alpacas, the alpaca having been raised for its wool and the llama for a beast of burden, for its wool, and also for its flesh for eating. The Peruvians excelled in the art of weaving. They made cloth, tapestry, gauze, and embroidery. They used cotton and wool for the most part, although there was a thread made from the fiber of the maguey. One of the principal occupations of the women was the preparation of the thread for weaving. In the early times it would seem that the loom was unknown but at the time of the entrance of the Spaniards into the country the work was done by true weaving on the loom. There were a number of designs used, variations showing from one period to another. Various colors were used. The patterns were woven in the material or placed on the cloth in the form of embroidery or painted on the cloth, and sometimes the cloth was ornamented with feathers placed on it in the form of patterns. They also wove a double-faced cloth in which the colors were different on the two sides. Delicate gauzes were made in which designs were embroidered on fine net background.
