“ This elevated plateau region is partially barren and inhospitable, its short, cold summers permitting the production of little besides potatoes, quinoa (Chenopodium quinoa) and barley, with a little Indian corn and wheat in favoured localities. Some attention is given to the rearing of llamas, and a few cattle, sheep and mules are to be seen south of Lake Titicaca. ”
