17^ THE HORSE 



of the sole, and lameness. The horse will often 

 start lame, and go perfectly sound after a mile or 

 two, and by this symptom may a corn be recog- 

 nized from other diseases of the foot. 



Causes. — Bad shoeing, and particularly the cut- 

 ting away of the bars and the paring out of the 

 seat of corn, whereby dirt accumulates in the hol- 

 low so made and causes injury. There is also a 

 predisposition to corns in fiat feet and feet with 

 wired-in heels, because undue pressure is liable to 

 come on the seat of corn. 



Treatment. — If the cause — ^pressure — is removed, 

 the corn will be cm^ed. A three-quarter shoe will 

 do this as a rule. Continual paring out will only 

 effect a temporary cure if the pressure is not also 

 removed. Some horses suffer from corns only in 

 the winter when in the stable, and become per- 

 fectly sound immediately they spend a portion of 

 their time at grass. In such cases, the dryness of 

 the feet when in the stable seems to be in part the 

 cause. In any case, the most important factor in 

 the prevention of corns is never to allow the 

 blacksmith to pare out the seat of corn.
