cries of wounded and suffering men; and among them the mother-coypú is seen with her progeny, numbering eight or nine, with as many on her back as she can accommodate, while the others swim after her, crying for a ride.

With reference to this animal, which, as we have seen, is prolific, a strange thing once happened in Buenos Ayres. The coypú was much more abundant fifty years ago than now, and its skin, which

has a fine fur under the long coarse hair, was largely exported to Europe. About that time the Dictator Rosas issued a decree prohibiting the hunting of the coypú. The result was that the animals increased and multiplied exceedingly, and, abandoning their aquatic habits, they became terrestrial and migratory, and swarmed everywhere in search of food. Suddenly a mysterious malady fell on them, from which they quickly perished, and became almost extinct.

The Desert Pampas. 13

What a blessed thing it would be for poor rabbit-worried Australia if a similar plague should visit that country, and fall on the right animal! On the other hand, what a calamity if the infection, wide-spread, incurable, and swift as the wind in its course, should attack the too-numerous sheep! And who knows what mysterious, unheard-of retributions that revengeful deity Nature may not be meditating in her secret heart for the loss of her wild four-footed children slain by settlers, and the spoiling of her ancient beautiful order!

A small pampa rodent worthy of notice is the Cavia australis, called cuí in the vernacular from its voice: a timid, social, mouse-coloured little creature, with a low gurgling language, like running babbling waters; in habits resembling its domestic pied relation the guinea pig. It loves to run on clean ground, and on the pampas makes little rat-roads all about its hiding-place, which little roads tell a story to the fox, and such like; therefore the little cavy's habits, and the habits of all cavíes, I fancy, are not so well suited to the humid grassy region as to other districts, with sterile ground to run and play upon, and thickets in which to hide.

A more interesting animal is the Ctenomys magellanica, a little less than the rat in size, with a shorter tail, pale grey fur, and red incisors. It is called tuco-tuco from its voice, and oculto from its habits; for it is a dweller underground, and requires a loose, sandy soil in which, like the mole, it may swim beneath the surface. Consequently the pampa, with its heavy, moist mould, is not the tuco's proper place; nevertheless, wherever there

is a stretch of sandy soil, or a range of dunes, there it is found living; not seen, but heard; for all day long and all night sounds its voice, resonant and loud, like a succession of blows from a hammer; as if a company of gnomes were toiling far down underfoot, beating on their anvils, first with strong measured strokes, then with lighter and faster, and with a swing and rhythm as if the little men were beating in time to some rude chant unheard above the surface. How came these isolated colonies of a species so subterranean in habits, and requiring a sandy soil to move in, so far from their proper district--that sterile country from which they are separated by wide, unsuitable areas? They cannot perform long overland journeys like the rat. Perhaps the dunes have travelled, carrying their little cattle with them.

Greatest among the carnivores are the two cat-monarchs of South America, the jaguar and puma. Whatever may be their relative positions elsewhere, on the pampas the puma is mightiest, being much more abundant and better able to thrive than its spotted rival. Versatile in its preying habits, its presence on the pampa is not surprising; but probably only an extreme abundance of large mammalian prey, which has not existed in recent times, could have, tempted an animal of the river and forest-loving habits of the jaguar to colonize this cold, treeless, and comparatively waterless desert. There are two other important cats. The grass-cat, not unlike Felis catus in its robust form and dark colour, but a larger, more powerful animal, inexpressibly savage in disposition. The second, Felis geoffroyi,

is a larger and more beautiful animal, coloured like a leopard; it is called wood-cat, and, as the name would seem to indicate, is an intruder from wooded districts north of the pampas.

There are two canines: one is Azara's beautiful grey fox-like dog, purely a fox in habits, and common everywhere. The other is far more interesting and extremely rare; it is called aguará, its nearest ally being the aguará-guazú, the Canis jubatus or maned wolf of naturalists, found north of the pampean district. The aguará is smaller and has no mane; it is like the dingo in size, but slimmer and with a sharper nose, and lias a much brighter red colour. At night when camping out I have heard its dismal screams, but the screamer was sought in vain; while from the gauchos of the frontier I could only learn that it is a harmless, shy, solitary animal, that ever flies to remoter wilds from its destroyer, man. They offered me a skin--what more could I want? Simple souls! it was no more to me than the skin of a dead dog, with long, bright red hair. Those who love dead animals may have them in any number by digging with a. spade in that vast sepulchre of the pampas, where perished the hosts of antiquity. I love the living that are above the earth; and how small a remnant they are in South America we know, and now yearly becoming more precious as it dwindles away.

The pestiferous skunk is universal; and there are two quaint-looking weasels, intensely black in colour, and grey on the back and flat crown. One, the Galictis barbara, is a large bold animal that
