The Hinder Shoe.—In forming the hinder shoe it should be remembered that the hind limbs are the principal instruments in progression, that in every act of progression, except the walk, the toe is the point on which the whole frame of the animal turns, and from which it is propelled. This part, then, should be strengthened as much as possible; and, therefore, the hinder shoes are made broader at the toe than the fore ones, and the toe of the foot, which is naturally broader than that of the fore-foot, is still further widened by rasping. Another good effect is produced by this, that the hinder foot being shortened there is less danger of overreaching or forging, and especially if the shoe be wider on the foot surface than on the ground one; and thus the shoe is made to slope inward, and is a little within the toe of the crust.

The shape of the hinder foot is somewhat different from that of the fore foot; it is straighter in the quarters, and the shoe must have the same shape. For carriage and draught horses generally, calkins may be put on the heels, because the animal will be thus enabled to dig his toe more firmly into the ground, and urge himself forward, and throw his weight into the collar with greater advantage. But the calkins must not be too high, and they must be of an equal height on each heel; otherwise, as has been stated with regard to the fore feet, the weight will not be fairly distributed over the foot, and some part of the foot or of the leg will materially suffer. The nails in the hinder shoe may be placed nearer to the heel than in the fore shoe, because, from the comparative little weight and concussion thrown on the hinder feet, there is not so much danger of contraction.

Different kinds of Shoes.—The shoe will vary in substance and weight with the kind of foot, and the nature of the work. A weak foot should never wear a heavy shoe, nor any foot a shoe that will last longer than a month. Here, perhaps, we may be permitted to caution the horse-proprietor against having his cattle shod too much by contract, unless he binds down his farrier or surgeon to remove the shoes once at least in every month; for if the contractor, by a heavy shoe and a little steel, can cause five or six weeks to intervene between the shoeings, he will do so, although the feet of the horse must necessarily suffer. The shoe should never be heavier than the work requires. An ounce or two in the weight of the shoe will sadly tell before the end of a hard day’s work. This is acknowledged in the hunter’s shoe, which is narrower and lighter than that of the hackney with even smaller feet than the hunter; and it is more decidedly acknowledged in the racer, who wears a shoe only sufficiently thick to prevent it from bending when used.

The Hunting Shoe.—The hunter’s shoe is different from that of the hackney in shape as well as weight. It is not so much bevelled off as the common concave seated shoe. Sufficient space alone is left for the introduction of a picker between the shoe and the sole, otherwise, in going over heavy ground, the clay will get in, and by its tenacity loosen, and even tear off the shoe. The heels likewise are somewhat shorter, that they may not be torn off by the toe of the hind-feet when galloping fast, and the outer heel is frequently and injudiciously turned up to prevent slipping. The reader will remember what we have just said of this. If calkins are necessary, let, at least, both heels have an equal bearing.

The Bar-Shoe.—A bar-shoe is a very useful contrivance. It is the continuation of the common shoe round the heels, and by means of it the pressure may be taken off some tender part of the foot and thrown on another which is better able to bear it, or more widely and equally diffused over the whole foot. It is principally resorted to in cases of corn, the seat of which it perfectly covers—in pumiced feet, the soles of which may be thus elevated above the ground and secured from pressure—in sand-crack, when the pressure may be removed from the fissure and thrown on either side of it—in thrushes, when the frog is tender, or is become cankered, and requires to be frequently dressed, and the dressing can by this means alone be retained. In these cases the bar-shoe is an excellent contrivance, if worn only for one or two shoeings, or as long as the disease requires it to be worn, but it must be left off as soon as it can be dispensed with. If it be used for the protection of a diseased foot, however it may be chambered and laid off the frog, it will soon be flattened down upon it; or if the pressure of it be thrown on the frog to relieve the sand-crack or the corn, that frog must be very strong and healthy which can long bear the great and continued pressure. More mischief is often produced in the frog than previously existed in the part which was relieved. It will be plain that in the use of the bar-shoe for corn or sand-crack, the crust and the frog should be precisely on a level, and the bar should be the widest part of the shoe, to afford as extended bearing as possible on the frog, and therefore less likely to be injurious. Bar-shoes are evidently not safe in frosty weather; they are never safe when much speed is required from the horse, and they are apt to be wrenched off in a heavy, clayey country.

Tips are short shoes reaching only half round the foot, and worn while the horse is at grass to prevent the crust being torn by the occasional hardness of the ground, or by the pawing of the animal; and the quarters at the same time being free, the foot disposed to contract has a chance of expanding and regaining its natural shape.

The Expanding Shoe.—Our subject would not be complete if we did not describe the supposed expanding shoe. It is either seated or concave like the common shoe, with a joint at the toe, by which the natural expansion of the foot is said to be permitted, and the injurious consequences of shoeing prevented. There is, however, this radical defect in the jointed shoe, that the nails occupy the same situation as in the common shoe, and prevent, as do the nails of the common shoe, the gradual expansion of the sides and quarters, and allow only of a hinge-like motion at the toe. This is a most imperfect accommodation of the expansion of the foot to the action of its internal parts, and even this accommodation is afforded in the slightest possible degree, or rather can scarcely be afforded at all. Either the nails fix the sides and quarters as in the common shoe, and then the joint at the toe is useless; or, if that joint merely opens like a hinge, the nail-holes in the shoe can no longer correspond with those in the quarters which are unequally expanding at every point; and, therefore, there will be more stress on the crust at these holes, which will not only enlarge them, and destroy the fixed attachment of the shoe to the hoof, but will often tear away portions of the crust. This has, in many cases, been found to be the effect of the jointed shoe: the sides and quarters of the foot have been broken until it has become difficult to find nail-hold. This shoe, to answer the intended purpose, should consist of many joints, running along the sides and quarters, which would make it too complicated and expensive, and frail for general use.

While the shoe is to be attached to the foot by nails, we must be content with the concave seated one, taking care to place the nail-holes as far from the heels, and particularly from the inner heel, as the state of the foot and the nature of the work will admit; and where the country is not too heavy nor the work too severe, even omitting the nails on the inner side of the foot. Shoes nailed on the outer side, and at the toe, are more secure than some would imagine, while the inner quarter will be left free, to prevent contraction, or to arrest its progress.

The attempt, however, to lessen the evils produced by shoeing is most praiseworthy; and men like Mr. Bracey Clark deserve the respect and thanks of the public, although their labours may not be crowned with success. Every contrivance permanently to fix the shoe on the foot without the use of nails, has failed; but a make-shift shoe has been contrived, and is to be procured at most saddlers, which is easily carried in the pocket, and put on in a minute or two if a shoe is lost in hunting or on the road; and which will remain securely attached to the foot, and prevent injury to it, during a journey of thirty or forty miles.

Felt or Leather Soles.—When the foot is bruised or inflamed, the concussion or shock produced by the hard contact of the elastic iron on the ground gives the animal much pain, and causes a short and feeling step, or even lameness, and aggravates the injury or disease. A strip of felt or leather is sometimes placed between the seating of the shoe and the crust, which, from its want of elasticity, deadens, or materially lessens the vibration or shock, and the horse treads more freely, and is evidently relieved. This is a very good contrivance while the inflammation or tenderness of the foot continues, but a very bad practice if constantly adopted. The nails cannot be driven so surely or so securely when this substance is interposed between the shoe and the foot; the contraction and swelling of the felt or leather, from the effect of moisture or dryness, will soon render the attachment of the shoe less firm; there will be too much play upon the nails; the nail-holes will enlarge, and the crust will be broken away.
