FOOT DISEASES. 101 



ground firmly and without lameness. Remember, that 

 in all cases of pricks and other injuries which end in sup- 

 puration, as pus in the foot of a horse, make a thorough 

 opening so as to allow the pus to escape, and no more 

 trouble need be apprehended ; except the nail has entered intc 

 one of the tendons of the foot, in that case no pus will be 

 usually formed, the majority of cases ending in locked-jaw, 

 (which see). Where pus is formed after pricking, no 

 locked-jaw follows; it is in those cases only where pus is 

 not formed that locked-jaw may be expected. 



(7.) Bruises of the Foot. — (Treat as for Prick of Foot], 



(8.) Sand or Quarter Crack. — This is a crack or split 

 in the hoof, usually on the inner side of the fore foot, al- 

 though splits and cracks occur in all places, and in both 

 fore and hind feet. 



Causes. A brittle condition of the hoof, from the want 

 of sufficient moisture. In some cases the horse does not 

 stand square upon his fore feet, thereby causing undue 

 weight to fall upon one of the sides of the hoof and causing 

 it to crack. 



Prevention. Apply to brittle feet equal portions of the 

 oil of tar, and cod liver oil, whale oil, or any fish oil well 

 rubbed in with a brush to the hoofs a few times a week; 

 and occasionally apply wet cloths to the feet in the sum^ 

 mer season. In winter the feet are better supplied with 

 moisture. 



Treatment. Easp the edges of the crack thin, the nearer 

 the crack the thinner the horn should be made; this can be 

 filled up with shoemaker's wax. After the horn has been 

 properly thinned a piece of the wall of the hoof, for about 

 half an inch on each side of the crack, is to be cut out to 

 prevent any bearing of the shoe upon it, thereby prevent- 

 vig the constant opening, shutting, and sometimes bleeding
