SHOEING. 



Fig. 411. 



Showing the exact outHnes of the hoof, Fig. 410, with the 

 form of adjustment and nailing of shoe as usually done. The 

 shoe and nails are too large, and the nails too many in num- 

 ber. The shoe set too far back, and the nails driven so high 

 and deep as to endanger driving into the quick, the real 

 cause of harm being made apparent by reference to Figs. 421 

 and 422. The hoof is rasped away so much as to weaken and 

 destroy its symmetry ; a common cause, as will be seen, of 

 destroying the natural adjustment of good feet, and so weak- 

 ening the wall and sole as to produce lameness and contrac- 

 tion.
