20 RATIONAL HORSE-SHOEING, 



the better in escaping this unnecessary inflic- 

 tion. 



THE BEVEL OF THE FOOT SURFACE 



Is to keep the shoe a continuation of the 

 crust or wall of the hoof, and to avoid per- 

 cussion upon the sole. 



THE BEVEL ON THE GROUND SURFACE 



Is to follow the natural concavity of the foot 

 and to give it the form which will have no 

 suction on wet ground, will n >t pick up mud, 

 or retain snow-balls. 



THE CALKS 



Have a use fully explained. 



When the shoe thus described is set so as 

 to secure frog pressure, as hereinafter directed, 

 a horse may be shod without violation of 

 nature's laws ; foot disease, under fair condi- 

 tions, will become almost impossible, and the 

 useless refuse-stock, broken down by the old 

 method, may be restored to usefulness.
