In respect to the domestic pacos; they are employed to carry burdens, like the lamas; but they carry a much less weight even in proportion to their size. They are likewise of a more stubborn nature, and when once they lie down with their load, they will suffer themselves to be cut to pieces sooner than rise. The Indians never make use of the milk of these animals, because they have scarcely enough to supply their own young. The great profit derived from their wool, induced the Spaniards to endeavour to naturalize them in Europe: they transported numbers of them into Spain, but the climate was so inimical to their nature that they every one perished: nevertheless, I am persuaded, as I have already observed, that these animals, more valuable than the lamas, might live and procreate upon our mountains, especially upon the Pyrennees. Those who brought them into Spain, did not consider that they cannot exist even in Peru, but in the cold regions, that is on the tops of the highest mountains; that they are never to be found in the valleys, and die if brought into warm countries. That on the contrary, they are still very numerous in the neighbourhood of the Straits of Magellan, where the cold is much greater than in the south of Europe; and that, consequently, in order to preserve them, they should be landed, not in Spain, but in Scotland, or even in Norway; or probably with greater certainty at the foot of the Pyrenean, Alpine, or other mountains, where they might climb to the region that most agrees with their nature. I have dwelt the more on this subject, because I imagine these animals would prove an excellent acquisition to Europe, and would produce more real advantage than all the metals of the New World, which only load us with a useless weight; for before the discovery of those mines, a pennyweight of gold or silver was of as much value as an ounce is at this present time.
