by shoeing treatment, the same as for interfering mentioned 

 above. 



Calk wounds. — These are wounds near the top of the hoof 

 and are caused by sharp-shod horses either trampling on them- 

 selves or on each other. Heavy draft horses are more subject 

 than lighter ones, and the fore feet more liable to injury than 

 the hind ones, though they often result in the hind feet from the 

 horse resting one foot on top of the other. The treatment is the 

 use of boots properly to protect the top of the hoof, and shoeing 

 the foot causing the injury with blunt calks. When the wound 

 is not deep and soreness slight, cold water bandages and a pro- 

 tective dressing, such as carbolized vaseline, will be all that is 

 needed. 



Corns result from bruises of the sole. They occur on the in- 

 side half of the sole of the front feet. Corns often accompany 

 weak flat feet, and often result from poor shoeing. The treat- 

 ment is to discover the cause and if possible remove it. Give 

 the horse rest. Horses subject to corns should be shod with 

 wide-webbed bar shoes, as these protect the foot. As to a cure, 

 the blood or pus that has collected needs to be removed. To do 

 this cut a hole through the sole of the foot, allowing the fluid to 

 escape. Wash in warm water and apply a 5 per cent solution 

 of carbolic acid, turpentine pure or white lotion. When the 

 discharge has ceased, apply pine tar to the opening to keep out 

 the dirt. 



Punctured wounds of the foot. — The foot of the horse is 

 liable to wounds made by some sharp object puncturing the sole 

 or the frog and injuring the soft tissues. Such wounds may 

 become serious and hence should receive close attention. Te- 

 tanus or lockjaw often follows such wounds in the horse. Such 

 wounds are caused by nails, sharp rocks, glass, wire, and the like. 

 They often cause lameness. The treatment is first of all to 

 withdraw the object. If pus and blood has collected, the hole 

 must be enlarged to facilitate drainage and the sole washed with
