So much for the ordinary 'possum. There is another sort found that is no doubt indigenous, and it is of a kind to make the eyes of a colored brother bulge with astonishment, for it is at maturity the size of a small meadow mole. There are bushes on the desert large enough to serve these little fellows as trees, and they are, therefore, able to follow their instinctive desire to climb and hang head down by the tail, but the spectacle of one of the little 'possum mothers climbing about a desert bush with her tiny young clinging to her is one of the most interesting sights in nature.
Another animal that is at least in one respect allied to the 'possum is the coypu. It might, perhaps, be called an aquatic 'possum because of its hairless tail and its habit of carrying its young on its back. The naturalists, however, say it is more like the beaver than any other North American beast, and it certainly has a remarkably beautiful pelage. Its flesh is very good to eat, but it is chiefly hunted for the fur. The feature of this animal, however, that at once attracts the attention of a stranger is the location of the nipples of the mother on her back instead of on her breast and belly, as in ordinary mammals. When seen swimming about with her young on her back, as is her custom, the nipples are found above the water line extending in a row from shoulder to hip, where the young can nurse as they are carried along.
Of the weasels, one kind is described as much larger than those in the United States. They travel in packs like wolves when hunting, and are said to have the most malignant and devilish faces of any beast of the desert. All birds and rodents that get within their grasp are torn to pieces in savage fashion.
Along the Andes many Virginia deer are found, but it is only near the forests. They emit a rank odor from the leg glands that is said to be fatal to the desert snakes. The gray fox flourishes everywhere and grows to a rather larger size than in the United States, but he is remarkable for being very short-winded. At least, he is easily tired out. A race of a few hundred yards with a desert horse uses him up, and he falls a victim to the well-nigh unerring bolas of the plainsmen. He is not often killed by the Indians, for he is not fit to eat, but the shepherds slay him at sight because of the number of lambs he kills in the season.
Then there is the skunk, a counterpart in all respects of the skunk of the States. Skunks are very numerous in all parts, and often serve the Indians as food when larger game fails. It is an interesting fact, too, that the Indians capture them when young and make pets of them. There is rarely a collection of wigwams on the desert without a couple of tame skunks playing about.
The skunks, when tame, seem in all respects inoffensive. The gauchos I met when told that a skunk's bite is supposed in parts of the United States to cause a malady akin to hydrophobia were incredulous. They had never heard of such a thing.
Any reference to the animals of Patagonia that omitted the armadillo would be noticeably defective. It is an animal with habits that must interest an amateur naturalist greatly. There are two forms of the armadillo. Roughly speaking, one is like a hairy guinea pig with a pointed turtle shell over its back and head, while the other is like a thick turtle without any breastplate. The former is very rare even in its haunts on the Andes. The latter is everywhere abundant. As described by all who have seen it, the latter will eat and get fat—very fat—on anything from grass roots to decayed fish or cattle, from an ant to a poisonous serpent, from strawberries to rats and mice. In the wilderness it roams about by day because the cats of the desert persecute it most at night. Near the settlements, where, by the way, it thrives best, it is abroad at night, because man persecutes it in the day. Slow moving, as it seems to be when the traveller sees it at sunset, it overtakes the serpents of the region in a fair race, and kills them by squatting on them and sawing its body to and fro so that the edges of its protective shell cut the snake to pieces. It captures mice by sneaking on them cat-fashion and throwing its body over them like a trap. It grubs for worms; it robs nests of eggs and fledglings. Now, although it eats a great many things that are repulsive to civilized tastes, the armadillo is itself a most delicious article of food for any human taste, civilized or uncivilized. In my journeys as a reporter of The Sun I have eaten nearly every kind of fish, flesh, and fowl served between Ivigtut, Greenland, and Ushuaia, Tierra del Fuego, but found nothing quite so much to my taste as an armadillo baked in the embers of an out-door fire on the desert of Patagonia. Nor was my judgment in the matter influenced by hunger, for my first armadillo was served unexpectedly after a plentiful repast of good beef roasted on a spit. It is said that armadillos are not found south of the Santa Cruz River. They are indigenous north of it, but the river's current is an impassable barrier to keep it from spreading south.
All travellers familiar with the desert regions of the United States are at once struck on reaching Patagonia with the remarkable similarity between the two countries. No one could object to the transplanting of armadillos to the prairies and deserts of the United States. They prefer animal food; they are good scavengers. They do no harm to crops, but on the contrary aid materially in destroying insects and other crop enemies. Indeed, they are so valuable in this respect that the Agricultural Department, which imported bugs of one kind to destroy others that were ruining California orange-growers, might well take into consideration a proposition to import armadillos.
Space is lacking even for brief reference to other animals. There is one thing, however, about the majority of all the desert animals that must strike the traveller as the most remarkable thing in nature. The big guanacos, the tiny rodent, half a dozen different kinds of mammals, besides birds, all live without water. I do not know this to be true, but every plainsman with whom I have talked said it was so. The panther, of course, finds a substitute in the blood he drinks, but there are others that do not have even a liquid food. They live on flesh or on the herbs that are never noticeable for having juices in them. Still, the matter is not without a parallel in the United States, for the prairie dogs, the rabbits, and the reptiles of such regions as the Panhandle of Texas and the Colorado Desert live in like fashion.
