The cause of this defect is the same as in quarter crack. It appears in both fore and hind feet. Clean the crack well, cutting with a sharp knife the dead horn from each side of it; shoe as advised for quarter crack, or for the purpose of getting expansion and natural action of the dead, shelly hoof.

This miserable condition of the abused animal is Nature's fiercest protest against the ignorance and carelessness of man. A horse set upon heavy shoes, and those armed with calks at toe and heel, such as are usually inflicted upon large draft-horses, has his whole weight placed upon the unsupported sole. The frog never comes in contact with the earth in any way, inflammation of the sensitive frog and sole takes place, and the arch of the sole bends down under the pressure until the ground surface of the hoof becomes flat or convex, bulging down even lower than the cruel iron that clamps its edge. This is the condition of a drop sole. This degenerate state of the foot has other complications. Active inflammation is often present and all the wretchedness of a pumiced foot—the despair of owner and veterinary—is experienced. The smith, whose clumsy contrivance has been the cause of all the woe, has abundant reasons to offer for the disease, and his unfailing resort of the "Bar Shoe." This atrocious fetter is supplemented with leather pads, sometimes daubed with tar, and the horse hobbles to his task. Not unfrequently the crust at the front of the hoof sinks in, adhering to the sole; circulation being cut off,
