 Poll Evil. 



This disease is similar to fistula and is in fact fistula of the head. It is 

 caused by hitting the head against a low beam or door. (For treatment see 

 Fistula, Page 163). 



Poll Evil. 



Quarter-Crack. 



A fissure in the front wall of the hoof of the hind leg is called a toe-crack. 

 When in the front feet it is called a sand or. quarter-crack. They are caused 

 by dry wall of the hoof, or a change from damp to dry roads, floors, etc. 

 Thick hoofs on small feet are subject to cracks. Heavy nails, improper nail- 

 ing, cankers, quittor or corns with pus cause cracks. 



Symptoms. A fissure is usually the only sign. A discharge often comes 

 from the crack, inflammation is present, also slight lameness. 



Treatment. Prevent enlargement of cracks. Keep the horn of hoof well 

 oiled. Put clasps on fissures. Poulticing the hoof gets it back into good 

 condition. Sometimes a leather "shoe" will keep the sand out. 



Quittor. 



This is a disease of a fistulous nature on the foot which causes pus to 

 form and flesh to slough off. It occurs in both fore and hind feet. The heels 

 and quarters are most liable but the coronet or top of the hoof is also at- 

 tacked. Bruises in which infection develops from mud, foul water, etc., are the 

 widest source of this ailment. Heavy horses with heavy hanging hair on the 

 fetlocks and thick skins are most usually affected.
