There is a pretty fable of a cat and dog lying in a dark room, aptly illustrating the fine senses of these two species. "Listen! I heard a feather drop!" said the dog. "Oh, no!" said the cat, "it was a needle; I saw it." The horse is not commonly believed to have senses keen as that, and a dog tracing his master's steps over the city pavement is supposed to be a feat no other animal can equal. No doubt the artificial life a horse lives in England, giving so little play to many of his most important faculties, has served to blunt them. He is a splendid creature; but the noble bearing, the dash and reckless courage that distinguish him from the modest horse of the desert, have not been acquired without a corresponding loss in other things. When ridden by night the Indian horse--and sometimes the same habit is found in the gaucho's animal--drops his head lower and lower as the darkness increases, with the danger arising from the presence of innumerable kennels concealed in the grass, until his nose sweeps the surface like a foxhound's. That this action is dictated by a powerful instinct of self-preservation is plain; for, when I have attempted to forcibly drag the animal's head up, he has answered such an experiment by taking the bit in his teeth, and violently pulling the reins out of my hand. His miraculous sense of smell measures the exact position of every hidden kennel, every treacherous spot, and enables him to pass swiftly and securely over it. On the desert pampa the gaucho, for a reason that he knows, calls the puma the "friend of man." The Arab gives this designation to his horse; but in Europe, where we do not associate closely with the horse, the dog naturally takes the foremost place in our affections. The very highest praise yet given to this animal is probably to be found in Bacon's essay on Atheism. "For take an example of a dog," he says, "and mark what a generosity and courage he will put on when he finds himself maintained by a man, who is to him in place of a god, or _melior natura,_ which courage is manifestly such as that creature, without the confidence of a better nature than its own, could never attain!" Can we not say as much of the horse? The very horses that fly terror-stricken from the smell of an Indian will, when "maintained by a man," readily charge into a whole host of yelling savages.
