Corn is not generally reckoned unsoundness. If a horse be lame from corn, the lameness renders the horse unsound; but the corn does not. Such is the beauty of horse logic when pronounced in a court of justice! A corn may suppurate, or may provoke lameness at any moment. Still the corn, in the bleared eye of the law, is no sufficient objection to the purchase of a horse. The suppurated corn may lead to quittor--still, corn is not legal unsoundness. It is a pity such is the case, since it leads men to neglect that which is removable. When the sole is high, the shoe should always be accompanied by a leathern sole. Liquid stopping should be poured into the open space at the back of the foot; and at every time of shoeing, the smith should pare the sole quite thin, even until drops of blood bedew the surface of the horn. When corns appear in flat or fleshy feet, as shoeing time comes round, only have the very ragged portions of the frog taken away. Have the web of the shoe narrowed so as to remove all chance of pressure against the iron. Lower the heels of the shoe, or try a bar shoe with the bearing taken off over the seat of corn; should that not answer, next put on a three-quarter shoe: many horses, however, will go sound in tips, that cannot endure any other sort of protection to the foot. By resort to one or the other of these measures, that injury, which in the learned eye of the law is of no consequence, but which, nevertheless, may lead to terrible lameness, or even lay the foundation for a quittor, may be greatly mitigated. =Bruise of the sole= is an accident leading to effusion of blood--so far it resembles corn; but it is dissimilar in not occurring on a part subject to the same degree of motion, and, therefore, is not so severe in the consequences to which it leads. It is caused by treading on a stone, and is removed by paring off the horn which has been discolored or lies immediately beneath the injury. It seldom leads to great lameness or gives rise to serious results. It is treated after the manner directed for corn; but it is always advisable to shoe once, with leather, the horse which has suffered from bruise of the sole. The difference between corn and bruise of the sole is simply this: the first is an injury produced by a cause which is always within the control of the proprietor, and which, if neglected, is likely to lead to the most disastrous maladies; the last is purely an accident, to which any horse at any time is liable, and with ordinary care is not likely to give rise to any serious consequences.
