waste no time in injecting the sinus, (which is practised by 

 many,) but make a small opening in the sole, as near the 

 base of the sinus as possible, and invite a discharge from it 

 by means of a poultice placed only in contact with the sole. 

 A free discharge once secured from the lower outlet, we 

 have no fears of a cure. So soon as a discharge sets up, 

 inject from below strong tincture of bloodroot, two or three 

 times, and then sprinkle some bloodroot in the cavity ; 

 there is no need of any bandage ; let the matter have free 

 vent. The upper orific:) wdli now close; it is only neces- 

 sary to moisten this region with compound tincture of aloes, 

 or some other traumatic. 



During this treatment the horse must be kept on light, 

 soft food, and his bowels must be kept in a somewhat re- 

 laxed condition. 



Over-reaching consists in the striking of the heel of the 

 fore foot with the toe of the hind shoe. It seldom occurs 

 except in saddle-horses which are too slow in moving their 

 fore feet, and this faulty action may be remedied by training 

 the horse to a light "gathered" movement, as directed in 

 the chapter on Baucher's method of training. When a 

 wound has been inflicted by over-reaching, the best treat- 

 ment is to dry up the discharge as soon as possible, which 

 may best be done by the use of tincture of arnica, of full 

 strength, or, in the absence of this, of gunpowder. If 

 the discharge is allowed to continue, it is ver}^ apt to de- 

 generate into Quittor^ and to cause much trouble. 



The cut of the heel in over-reaching is caused not by 

 the clip of the hind shoe, but by the back part of the web 

 at the toe of the shoe, which, being made square at first, 

 is soon worked to a sharp edge. If, when the shoe is 

 made, that part of the web be filed to a round edge, there 

 will be little danger of a severe cut.
