Besides the grass field, foul lodging or filth and poor provender will breed mange in the horse, as the same causes operating upon the human subject will engender a like disorder. It is sad to think that with the horse, as years increase, ailments accumulate and strength departs; it is sad to think, that as the animal's life becomes more hard to sustain, its food is always the less nourishing and its labor the more exhausting; that as care is necessary, so is neglect encountered; that the wretched quadruped at length is sold to some costermonger, who, when he makes the purchase, nicely calculates how many days of labor the emaciated life is capable of before it is turned over to the knacker. Many a nobleman must have looked upon an animal in the last stage of a weary life which was formerly the companion of his pleasures. The rusty, lean, and worn-out carcass most probably was not recognized, or how must reflection have whispered that power was not given to turn away existence into wretchedness after willfulness had rendered the body less capable of sustaining suffering! In the vast majority of cases this disease first appears in the mane, among the hairs of which a quantity of loose, dry scurf is perceptible. Before such a sign, however, is to be recognized, excessive itchiness is exhibited. The disease, once established, soon extends to the head, to the neck, to the withers, to the sides, to the loins, and to the quarters; only in very exceptional cases are the legs exposed to its attacks. As the disorder proceeds, the hair falls off, leaving vacant places upon the body; these have a peculiar, dry, acrid, and irritable appearance; they suggest that portions of the body have been scorched with quick-lime, so irregular, patched, and scabby are the parts just referred to. The integument in these places greatly thickens and is no longer soft and pliable as a lady's glove, but becomes corrugated or thrown into well-defined folds. The hairs, however, are not all removed; a few and only a few remain; these cling with exceeding tenacity to the surfaces which their fellows have quitted. The force required to pull out one of these remaining hairs is somewhat surprising, and the hair being extracted, the roots, upon close examination, will be discovered enlarged and far more vascular than is usual.
