the pressure, they turn black, and then smell abominably. The putrid 
action, having once commenced, is apt to extend, and portions of the 
coffin-bone are likely to exfoliate. 
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 bleed- 
ing 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 ex- 
tended the length of the hoof, you must make 
a line at each extremity with a heated iron, as

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 inten- 
tion, 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 consider- 
ation 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 sys- 
tem 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 con- 
tinue 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. 
If the horse must go to work, remember, it should not be in the shafts, 
upon long journeys, or with a heavy load behind it. Before the animal
