OF SHOEING. 29 



heels, where the crust gradually comes to a point 

 and forms a* junction with its bars, the shoe must 

 likewise come to a point, the inner edge of its heels 

 exactly following and resting on the bars. The 

 double bearing thus given to the shoe by its inner 

 edge resting on the bars prevents the possibility of 

 any undue pressure from it coming on the seat of 

 corn. 



The narrowing of the web of the fore shoe at the 

 heels may seem unnatural to those who are accus- 

 tomed to it ; but if it is the shape, as it undoubtedly 

 is, which nature has chosen for the crust and bars 

 at their junction, can it be either unnatural or un- 

 suitable ? 



The ordinary square or rounded heels of fore 

 shoes are objectionable, because that part, which 

 overlaps either the bars or crust, rests on nothing, 

 and moreover affords the ground a handle, by which, 

 as it were, to wrench off the shoe. 



33. The outer line of the shoe must accurately Fitting of 

 follow the crust everywhere ; it must not be one 

 particle smaller than the crust, nor overlap it in the 

 slightest degree. 



If a shoe be applied smaller than the crust, and 

 such is the ordinary practice, the crust must be 

 rasped down to it. If the shoe be larger than the 

 crust, treads and other injuries are the result, and 

 in deep ground the shoe may be pulled off.
