Some horses are not so easily confined at pasture. They break or leap the fences, and wander over the country, or proceed to the stable. The fore feet are sometimes shackled in order to confine them; but these fetters, if long worn, are apt to alter the horse's action, rendering it short, confined, irregular, at least for a time, till he regain the use of his shoulders. Sometimes the horse is tied by a rope to a stake driven in the ground. He requires almost constant watching, for he must be often shifted as he eats down the grass, and he may get his legs entangled in the rope. He may cast himself, and receive severe injury, without he be immediately relieved. Sometimes the horse is tied to a stake, which he can drag about the field. He soon finds that he can walk where he pleases, but he can no run, and seldom attempts to leap. This also is liable how ever, to throw the horse down, or injure his legs by getting them entangled in the rope. To prevent the horse from leaping, a board is sometimes suspended round his neck, and reaching to the knees, which it is apt to bruise. None of these clumsy and unsafe restraints should ever be employed when it is possible to dispense with them. Few horses mares in springs and stallions excepted, require them after the first two days.
For horses that are turned out only an. hour or two during the day, they are as much used to render the horse easily caught when wanted, as to prevent him from wandering.
