LAMENESS AND DISEASES, ETC.

Having done this, if the foot be contracted at the heel, 

 pare it to a level. The toe of the foot is then in turn to be 

 shortened and the heel weakened by paring out the commissures 

 between the bars and frog as much as, in the judgment of the 

 farrier, the foot can safely bear. The pattern of shoe represented 

 by Fig. 35 should be used upon the horses intended for draft 

 purposes, the nails being placed from the front of the quarters 

 back toward the heel. Clips should be used upon each side 

 of the toe of the shoe, so that when placed upon the foot on each 

 side of the fracture, they will prevent the foot from further ex- 

 pansion, by keeping the pressure off from the toe, as shown in 

 Fig. 57. The toe calkin being placed well back from the 

 toe, lightens the stress at the point where the greatest weakness 

 exists, and allows of an easier play to the foot when in motion. 

 When the split occurs in the foot of a general business horse, 

 lower the heel and shorten the toe, as much as safety will 

 permit, and thin the heel of the shoe to obtain strong frog 

 pressure^ removing the 

 pressure around the toe of 

 the foot as before directed. 



Quarter Cracks. — 

 Quarter cracks are longi- 

 tudinal fissures in the 

 hoof, occurring near the 

 heels. They are gener- 

 ally occasioned by im- 

 proper shoeing, or neglect 

 of the foot ; or by allow- 

 ino- the horse to stand on

 time, or in the overgrowth of the crust ; or when the frog, sole and
