Pumice Foot
(See Plate No. 23) should always be pared out on each side of the frog until it yields to the pressure of the thumb. This paring should, however, be done immediately around the frog, leaving more than the usual ground surface (see plate After Treatment). The toe should be shortened as much as possible, and the heels cut out back. If the horse is lame a bor shoe is the best to protect the foot, with a leather sole, and some spirits of tar as a moisture. This shoe should be renewed at least once a month, with a leather sole, until a cure is effected.
