54 THE CANADIAN HORSE 



thoroughly, and relieve it from the pressure of detached horn ; 

 then smear it over with a little tar, to keep flies and dirt from 

 it, and it soon heals up ; but when lameness is severe, matter 

 is forming, and must be freely opened up, else the matter 

 burrowing beneath the hoof forms pipes and sinuses, con- 

 stituting quittor. 



If the hoof has been split, it must be treated as directed 

 for sand-crack. Not unfrequently, in bad cases, fungus- 

 growths spring up, which must be removed by caustics and 

 pressure, or the actual cautery. 



OVEEEEACH. 



When a horse, in a fast pace, over-reaches the fore with 

 the hind-foot, the inner rim of the shoe cutting a semi- 

 circular flap on the heel or quarter, it is called an " over- 

 reach." It should be treated as a tread; but when prac- 

 ticable, the edges should be brought together by a wire suture, 

 and bound up with Friar's balsam, or tinct. benzoin co. 



/ QUITTOE./ 



In all cases in which matter forms in the foot, whether 

 from pricks, corns, bruises, or treads, unless it has free open- 

 ings to escape by, it acts as an irritant, extending in every 

 direction, forming sinuses, and at last working its way to 

 the coronet, where it bursts, producing a very troublesome 

 disease, and requiring both patience and perseverance to 

 effect a cure.' 



Symptoms. — It is recognised by the small aperture at the 

 coronet, which seems almost overgrown with " proud-flesh." 

 The discharge is glarey and constant. On examining it with 

 a probe, sinuses are found running in all directions. The 

 quarter is enlarged' and bulging, and the lameness severe 

 and protracted.
