The hind shoe ([Fig. 116]) is made in like manner, but the branches are not bent in a circle but given that form shown in [Fig. 106]. Concaving is not necessary; it is sufficient merely to round the inner edge of the web.

The curvature of a branch of a hind shoe.
Since in bending the shoe, and especially the toe of a hind shoe, the inner edge is crowded together (back-set) and thickened to the same extent that the outer edge is stretched and thinned, we must remember to do away with these inequalities of thickness and strain by hammering the shoe smooth.
Peculiarities of the Shoe.
They are dependent upon the structure, direction, and position of the leg and hoof, as well as upon the horse’s service and the nature of the ground. Since the shoe is an artificial base of support, and since a proper surface of support is of the greatest importance in preserving the soundness of the feet and legs, careful attention must be given to this matter. Naturally shoes designed for the various forms of hoofs must present equally great and equally numerous differences of form, as well as other peculiarities.
