Judging by the good qualities of the skins I have seen, the hide of the full-grown guanaco would make an excellent leather, well adapted for valises and such uses, while that of the younger ones would serve admirably for fine footwear and gloves. Skins bring from 25 to 50 cents gold each in the market at Punta Arenas.
A curious kind of ball accumulates in the stomach of the guanaco. It looks something like a stone, but can be readily broken. It is said to possess medicinal qualities, and there is a ready market for the stuff at the settlement.
Next to the guanaco in interest if not in utility is the panther of Patagonia, the _felis concolor_ of the naturalist. Nowhere in the world does the great tree-climbing cat reach greater size or accumulate more fat than on the treeless deserts of the far south. Specimens from eight to nine feet long over all are frequently seen. Though, perhaps, rather lighter in color, they are in all other respects exactly like the panthers of the United States. How it happened one cannot even guess, but the panther is known very much better in the desert than in the United States. Rarely can one read a story of the panther in the States without seeing something about its terrible ferocity toward human beings, while the stories of the panther that comes out of the woods to play with the lonely wayfarer as a cat plays with a mouse, that it may at last crush and eat him, are enough to make the flesh of the unlearned reader creep on his bones. On the desert of Patagonia there are more panthers in proportion to the area and the numbers of other kinds of animals than in any other region of the world. The lonely wayfarer is not often found there afoot, but men have been on the desert unmounted, and the panthers have come to play around them, too. But it is not as a predatory cat that they come. It is as a playful kitten. Individual panthers play by themselves--old ones as well as young--by the hour. They will chase and paw and roll an upturned bush, or a round rock, or any moving thing, and lacking that will pretend to sneak up on unwary game, crouching the while behind a bush, or rock for concealment, to spring out at last and land on a hump of sand or a shadow. Then they turn around and do the same thing over again.
