The dealers had a jargon of their own, in which my friend became an expert. They did not say that a horse weighed a thousand pounds, but ten hundred; he was not worth a hundred and twenty-five dollars, but one and a quarter; he was not going on seven years old, but was coming seven. There are curious facts, by the way, in regard to the age of horses which are not generally known. A horse is never of an even age: that is, he is not six, or eight, or ten, but five, or seven, or nine years old; he is sometimes, but not often, eleven; he is _never_ thirteen; his favorite time of life is seven, and he rarely gets beyond it, if on sale. My friend found the number of horses brought into the world in 1871 quite beyond computation. He also found that most hard-working horses were sick or ailing, as most hard-working men and women are; that perfectly sound horses are as rare as perfectly sound human beings, and are apt, like the latter, to be vicious. He began to have a quick eye for the characteristics of horses, and could walk round a proffered animal and scan his points with the best. "What," he would ask, of a given beast, "makes him let his lower lip hang down in that imbecile manner?" "Oh, he's got a parrot-mouth. Some folks like 'em." Here the dealer would pull open the creature's flabby lips, and discover a beak like that of a polyp; and the cleansing process on the grass or trousers would take place. Of another. "What makes him trot in that spread-out, squatty way, behind?" he demanded, after the usual tour of the block. "He travels wide. Horse men prefer that." They preferred any ugliness or awkwardness in a horse to the opposite grace or charm, and all that my friend could urge, in meek withdrawal from negotiation, was that he was not of an educated taste. In the course of long talks, which frequently took the form of warnings, he became wise in the tricks practiced by all dealers except his interlocutor. One of these, a device for restoring youth to an animal nearing the dangerous limit of eleven, struck him as peculiarly ingenious. You pierce the forehead, and blow into it with a quill; this gives an agreeable fullness, and erects the drooping ears in a spirited and mettlesome manner, so that a horse coming eleven will look for a time as if he were coming five.
