Now there are persons who attempt to deprive the sloth of the credit due to his laziness by explaining that his limbs are not adapted for use on the ground. This is a fact, although it is mean to use it to discredit so fine a reputation. The sloth is indeed a deal more active when he is hanging upside down by his toes--but then that is all a part of his system, since it is plain that his greatest state of activity is merely one of suspended animation. It is only when he is in a state of suspense that the sloth is really happy, and this is only one aspect of the topsy-turviness of his entire nature. Hanging horizontally, head and tail downward, is his normal position in society, and this is apt to lead to a belief among the unthinking that he must have lived long in Australia and there become thoroughly used to holding on to the world in his usual attitude; but his actual home is Central and South America--not altogether "down under" but merely on the slope. [Illustration: "GURN! I'LL--"] The sloth in this place is, in the eyes of most visitors, a mere mop in a heap of straw. Let but the keeper stir him up and he reveals himself gradually, the picture of a ragged, rascally mendicant--a dirty ruffian whose vocation can be nothing more laborious than extorting coppers on pretence of sweeping a crossing. A little more stirring, and he will reach for his perch and invert himself, to think things over. To him the floor is inconvenient, for it is his ceiling; anybody's ceiling is inconvenient to crawl about on. [Illustration: A DIRTY RUFFIAN.] When one knows that the sloth never drinks, one is prepared to believe that he persistently refuses to stand; but then nobody can stand anything, even drinks, on a ceiling. If by any chance he finds himself on the ceiling (which, as I have said, is his word for floor), he can only hook his claws wherever he sees a hole, and drag himself. He is the poorest of all the Dasypidæ in the matter of tail, and was also unfortunate in the allotment of toes, only wearing two on each fore-foot. Which disposes of the sloth. [Illustration: DISPOSED OF.] Of the Dasypidæ there are only, beside the sloth, various armadillos and an ant-eater in this place. The armadillo is a placid creature, with none of the warlike disposition that its armour might lead some to expect. Mild and placable, as well as rather bashful, it has somewhat the character of a beplated and armed theatrical super, who plays the flute and teaches in a Sunday-school when off duty. It is susceptible to cold, too, and regardless of any heroism of appearance in face of a chill in the air. Withal the armadillo is indifferent alike to flattery and abuse: you can no more hurt his feelings than his back. [Illustration: MILD SUPERS.] [Illustration: A CHILLY PERSON.]
