(_e_) _The base-narrow hoof_ is just the reverse of the preceding, and requires a shoe whose peculiarities are described in paragraph 5, page 114. While in the normal standing position of the limbs, viewed from in front, the ends of the branches of the shoe should be equally distant from the middle of the median lacuna of the frog, this is not so in the base-wide and base-narrow positions. In the base-wide position the outer and in the base-narrow position the inner branch should be somewhat farther from the median lacuna than the branch of the opposite side. [Illustration: FIG. 123. The three principal forms of hoofs shod with flat shoes.] (_f_) _The wide hoof_ has too large a surface of support, and, therefore, the shoe designed for it should possess the peculiarities enumerated in paragraph 6, page 115. (_g_) _The narrow hoof_ has already too narrow a base of support, and must not be made smaller; therefore, the shoe should not have a base-narrow but a perpendicular outer border, as described in paragraph 7, page 115. Shoeing Saddlers and Hunters. _The shoes for saddlers_ (Park Hacks) should be light, short, and fitted snug to prevent forging, interfering and pulling of the shoes. The hoof-surface should cover the wall, white line and at least one-fourth of an inch of the margin of the sole. An average width of one inch is desirable. Both front and hind shoes should be fullered and concaved on the ground-surface (convex iron). =The Front Shoe=:—_Length_, should not project beyond the buttress more than one-eighth of an inch. _Width_, an inch at the middle on the branches, somewhat more at the toe, and less at the ends of the branches. _Bevelling_, outer border, base-narrow all around. The ends of the branches, and the heel-calks, in case they are used, are bevelled strongly downward and forward under the foot. The toe is rolled from the inner edge of the web, and provided with a strong central clip. Six nails are sufficient (see Fig. 124). [Illustration: FIG. 124. A right front shoe with forging calks; suitable for a saddle-horse, or hunter (convex iron).] =The Hind Shoe=:—_Length_, the shoe may project from one-fourth to three-eighths of an inch behind the buttresses. The toe should be well rounded and somewhat blunt so that the horn of the toe will project beyond the shoe an amount equal to one-half the thickness of the wall. _Width_, somewhat less than the front shoe. The branches are of equal thickness, and should carry heel-calks whose height equals the thickness of the shoe. To guard against interfering the inside calk may be omitted and the inner branch thickened, fitted snug and bevelled strongly base-narrow. Clips are to be placed at inner and outer toes. Seven nails are sufficient.
