Now to prevent this, so soon as the horse is brought in with a sandcrack, wash the part thoroughly with the chloride of zinc lotion, one grain to the ounce of water. The bleeding having ceased, pare down the outward edges of the separation, and put on a bar shoe, eased off at the toe, and with a clip on either side of the division. If the injury has not extended the length of the hoof, you must make a line at each extremity with a heated iron, as in quarter crack, than which it is also of more consequence that the coronet should be isolated; because the external horn being thickest at the toe, is the more likely by its movements to be influential upon the new and plastic horn of the coronet. [Illustration: A FOOT WITH TOE SANDCRACK. Illustrating the mode of shoeing with clips, and of easing off at the toe; also exemplifying the manner of paring down the hoof, and showing the part where granulations are likely to appear.] Should, however, the granulations have appeared, and the horse, with appetite lost and the head dejected, the pulse thumping and the injured foot held in the air, appear the picture of a living misery, first cleanse the wound thoroughly with the chloride of zinc lotion. Then apply a firing-iron, of a black heat, to the hoof, near to the crack. The intention, in doing this, is to warm and thus to soften the horn. This effect being accomplished, pare down or scoop off the edges--using the heated iron again, if necessary. Do all this leisurely, and with every consideration for the animal, which endures intense agony; for anything like violence or impatience tells fearfully upon the sufferer's system. The horn being lowered, take a very sharp drawing-knife, and, with one movement of the wrist, excise the granulation. Set down the foot, and leave it to bleed; the loss of blood will lower the inflammation and will benefit the internal parts. Give a little green-meat to cool the system and act upon the bowels. Then, with the constant use of the lotion, enough has been done for one day. The following morning you may again apply the lotion, and continue to use it afterward thrice daily. Any further lowering may also be accomplished to the edges of the crack, as well as the coronal portion of the horn be separated from the lower part of the hoof, by means of lines drawn as before illustrated.
