HORSESHOEING. 201 



be lowered sufficiently to prevent j)ressure from the shoe until 

 the next shoeing (Figs. 220, a, and 221, c). 



This method should he followed even when the jDerpendicular 

 line falls behind the buttress. 



The crack may be immobilized by the metal plate, or by 

 narrow ticking bandage or adhesive tape wound a half dozen 

 times around the hoof,, in conjunction with a bar-shoe, Chadwick 

 spring, leather sole and tar and oakum sole-packing. 



In dressing the hoof, the side containing the crack should 

 be spared, the opposite side lowered, the object being to shift 

 the weight and consequent expansion into the sound quarter. 

 W^ien the affected quarter is deficient in length the branch of 

 the shoe beneath should be made thicker, even to the extent of 

 causing it to ground in advance of the opposite branch. 



Next to shoeing, rubber hoof-pads render good service, be- 

 cause through them a part of the body-weight is distributed over 

 the sole and frog. They assist in widening the hoof, and lessen 

 shock when the foot is set to the ground. These are all matters 

 which favor the growing down of unbroken horn. 



When the crack gaps widely, and the frog is small and deep 

 in the foot a shoe unth bar-clips (Defay's shoe), or a Chadwick 

 spring, with bar-shoe and leather sole may be used. It is not 

 impossible, indeed, to obtain a cure by using an ordinary open 

 flat shoe, though much will depend upon the other lesions that 

 may be present, the nature of the hoof, and the service required 

 of the animal. 



If the edges of the crack are irregular and overlapping, 

 they should be carefully thinned away. Thinning the horn on 

 lx)th sides of the crack over the coronary band, preventing dry- 

 ing out of the horn, and frequent applications of carbolized oil 

 to the coronet favor growth of undivided horn and guard against 

 a renewal of the crack. 



If in the beginning of the disease there is inflammation and 

 lameness, cooling poultices should be used for several days. 

 When there is no lameness, the horse may be used for slow 

 draft purposes. Coach- and saddle-horses should he kept
