iption. In the Goodenough shoe, the calks are supplied, and the
weight so distributed that the objection to the old method does not
exist.

COUNTERSINKING THE NAILS.

This is a point to which we call attention as of great importance. In
shoeing a horse for light or rapid work with a common flat shoe, seven
or eight nail-heads protrude, and take the force of his blow on the
ground. The foot has just been pared, and those nails, driven into the
wall and pressing against the soft inside horn and sensitive laminae,
vibrate to the quick, and often cause the newly-shod horse to shrink,
and show soreness in traveling for a day or two. No matter how
skillfully shod, the horse will be all the better in escaping this
unnecessary infliction.

THE BEVEL OF THE FOOT SURFACE

Is to keep the shoe a continuation of the crust or wall of the hoof, and
to avoid percussion upon the sole.

THE BEVEL ON THE GROUND SURFACE

Is to follow the natural concavity of the foot and to give it the form
which will have no suction on wet ground, will not pick up mud, or
retain snow-balls.

THE CALKS

Have a use fully explained.

When the shoe thus described is set so as to secure _frog-pressure_, as
hereinafter directed, a horse may be shod without violation of nature's
laws; foot disease, under fair conditions, will become almost
impossible, and the useless refuse-stock, broken down by the old method,
may be restored to usefulness.

CHAPTER IV.

HOW TO SHOE SOUND FEET.

If a foot came to the farrier in a perfectly normal condition, never
having been subjected to the destructive process of common shoeing, the
directions for putting on the Goodenough shoe would be simply, to dress
the foot by paring or rasping the wall until a shoe of proper size laid
upon the prepared crust would give an even bearing with the frog all
over the foot; then, as the calk wore away, the pressure would come more
and more upon the frog and the foot would retain its natural state
during the life-time of the horse.

A colt thus shod could not have a corn, for a corn is an ulcer caused by
the wings of the coffin-bone pressing upon a hard, unelastic substance.
When the horse raises his foot the coffin-bone is lifted upward by the
action of the flexor tendon; when his foot touches the earth the weight
of the animal is thrown upon the same bone, and, if unsupported by the
natural cushion of the foot, t
