These are supposed to have been originally produced by Spanish dogs from Buenos Ayres, who, allured by the great quantity of carrion, and the facility they had by that means of subsisting, left their masters, and ran wild amongst the cattle; for they are plainly of the breed of European dogs, an animal not originally found in America. But though these dogs are said to be some thousands in a company, they hitherto neither diminish nor prevent the increase of the cattle, not daring to attack the herds, by reason of the numbers, which constantly feed together; but contenting {70} themselves with the carrion left them by the hunters, and perhaps now and then with a few stragglers, who, by accidents, are separated from the main body they belong to. Besides the wild cattle which have spread themselves in such vast herds from Buenos Ayres towards the southward, the same country is in like manner furnished with horses. These too were first brought from Spain, and are also prodigiously increased, and run wild to a much greater distance than the black cattle; and though many of them are excellent, yet their number makes them of very little value, the best of them being often sold in the neighbouring settlements, where money is plenty and commodities very dear, for not more than a dollar a-piece. It is not as yet certain how far to the southward these herds of wild cattle and horses have extended themselves, but there is some reason to conjecture that stragglers of both kinds are to be met with very near the Streights of Magellan; and they will in time doubtless fill all the southern part of this continent with their breed, which cannot fail of proving of considerable advantage to such ships as may touch upon the coast, for the horses themselves are said to be very good eating, and, as such, are preferred by some of the Indians even before the black cattle. But whatever plenty of flesh provisions may be hereafter found here, there is one material refreshment which this eastern side of Patagonia seems to be very defective in, and that is fresh water, for the land being generally of a nitrous and saline nature, the ponds and streams are frequently brackish. However, as good water has been found there, though in small quantities, it is not improbable, but on a further search, this inconvenience may be removed.
