Llama distinguished by the inhabitants of South America are recognized as distinct species, though with difficulties in defining their distinctive characteristics. These are: The llama and alpaca are only known in the domestic state, and are variable in size and of many colors, being often white, brown, or piebald. Some are grey or black. The guanaco and vicuña are wild, the former being endangered, and of a nearly uniform light-brown color, passing into white below. They certainly differ from each other, the vicuña being smaller, more slender in its proportions, and having a shorter head than the guanaco. The vicuña lives
Chile–Peru relations by constructing extensive forts such as the Valdivian fort system. In order to prevent other European nations from making colonies in these sparsely-populated areas, the trade of Chile became restricted to directly providing supplies, such as tallow, leather, and wine, to Peru. Moreover, a series of young officers in Chile made careers as governors of this territory, and a few even made it all the way to getting appointed viceroys of Peru (such as Ambrosio O'Higgins and Agustin de Jauregui y Aldecoa). This exchange of goods and supplies between both regions became the first recorded trade of both future nations.
