the fore part of the foot, towards the toe, and the toe itself thinned, whereby the compression on the parts is rendered somewhat less, by diminishing the strength of the hoof or crust.
'But this rasp is to be used with discretion, lest the crust being too thin, and not able to support the weight of the horse, a sandcrack ensue; which frequently happens from too free or unskilful use of this tool, and from the natural rigid texture of the coronet. The heel of the shoe, on all strong and narrow-heeled horses, should be made strait at the extreme points; the form of the shoe in some measure helping to distend the heel of the horse. For the same reason, the shoe on no horse should be continued farther than the point of the heel. It has been already said that neither frog nor sole should ever be pared; nevertheless, it must be understood that it is impossible to pare the crust without taking away some of the adjacent sole, and it is also requisite, in order to obtain a smooth and even surface, so far as the breadth of the shoe reaches, and no farther. The frog also will become ragged, and loose pieces will occasionally separate from the body thereof, perhaps in one foot, and not in the other. When this happens, it should be cut away with a knife, to prevent the gravel lodging therein. But if it be left to the artist to do, he will be sure to take away more of it at one time than will grow again in many weeks.'
He advocates calkins, or 'corking' the shoes, in winter only, when the ground is soft and slippery; and then says of his recommendations: 'This method of treating the foot, and such a kind of shoe as has been described, I have used many years; and, to the best of my remembrance,
