cient to lower the heel so as to remove the pressure of the shoe, then to cut 
away the corn as far as possible and dress it with muriate of antimony, put- 
ting ona bar-shoe. If the horse has strong feet, it may suffice to cut 
away the bars, put on tips without cutting down the heels, and dress witn 
‘muriate of ammonia. For riding-horses do not use bar-shoes, but thicken 
the shoe a little, or spring it at the heel. A three-quarter shoe has been 
used in such cases with great benefit and comfort to the horse. 
SANDCRACK. 
Sandcrack is a fissure or partition in the hoof, usually at the inside 
‘quarter of a fore foot, or in front of a hind one. Its chief causes are dryness 
and brittleness of the hoof from an injury to the crown-surface, or from 
a lack of the gluey matter which binds the fibers, the latter cause being 
common in warm, sandy countries. 
TREATMENT.—Remove all pressure of the shoe beneath the crack, a 
bar-shoe being the best in most cases. Arnica-lotion will relieve pain and 
lameness, and an application of powdered blood-root will check the appear- 
ance of proud flesh. Should the sensitive layers of the hoof be squeezed 
by the crack, resulting in lameness, thin down the edges of the horn at the 
crack and foment the foot frequently until all inflammation subsides. The

‘crack should be closed as soon as possible, and prevented from extending up 
to the crown. To this end, clean out the crack, rasp its edges thin, take a 
sharp, red-hot firing-iron, and if the sensitive layers be not exposed, run it 
slightly down into the crack until it causes a gluey discharge, which will 
hold the sides together. Then make short horizontal fissures nearly 
through the horn, one above and one below the crack, and cover them and 
the whole wall of the hoof with shoemaker’s wax, bound on with broad 
tape, to keep the edges of the crack together, to exclude moisture and dirt, 
and to protect the new horn as it grows from the top downward. The 
treatment may necessarily be long, but if carefully observed will effect a
