CHAPTER III.
DESCRIPTION OF THE GOODENOUGH SHOE.
From the representation of the shoe in the cut, its peculiar conformation will be observed, and the reason for these changes from the common form we shall endeavor to explain as clearly as possible. In the first place, it is very light, scarcely half the weight of the average old-fashioned shoe. The foot surface is rolled with a true bevel, making that portion of the web which receives the bearing of the hoof, the width of the thickness of the wall or crust. This prevents pressure upon the sole, and makes the shoe a continuation of the wall of the foot. The ground surface of the shoe has also a true bevel, following the natural slope of the sole, and bringing the inner part of the shoe to a thin edge. The outer portion is thus a thick ridge, dentated, or cut out into cogs or calks, allowing the nail-heads to be countersunk. This arrangement gives five calks--a wide toe-calk, the usual heel-calks, and two calks, one on each side, midway between the toe and heel--thus putting the bearing equally upon all the parts of the foot.
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.
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 lamin?, 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
