This calking has a double object. In the common system of shoeing, to avoid slipping in winter upon the ice, and in the cities upon the wet, slimy surface of pavement, or to assist draft, it is customary to weld a calk upon the toe of a shoe, and to turn up the heels to correspond. In this motion the horse is placed upon a tripod, his weight being entirely upon three points of his foot, and those not the parts intended to bear the shock of travel or to sustain his weight. The position of the frog is of course one of hopeless inaction, and the motion of the unsupported bones within the hoof produce inflammation at the points of extreme pressure, so that, in case of all old horses accustomed to go upon calks, there is ulceration of the heels, in the form of "corns," which the smith informs the owner is the effect of hard roads bruising the heel from the outside; he usually "cuts out the corn," and puts on more iron in the form of a "bar shoe." Or the same action which produces corns, acting upon the dead, dry, unsupported frog and sole, breaks the arch of the foot so that a "drop sole" is manifest, or "pumiced foot," for both of which a "bar shoe" is the unvarying, pernicious prescription. In the Goodenough shoe, the calks are supplied, and the weight so distributed that the objection to the old method does not exist.
