SHOEING.

FIG. 480. Shoe too short and thick, with nails driven 

 deep, and too far back in the quarters. 



used, the forward calk may be set well back in the toe, as shown 

 by illustration. 



The object of nailing should be to hold the shoe firmly to the 

 foot without injur- 

 ing the wall, and 

 leave the foot as in- 

 dependent of the re- 

 straint of the shoe at 

 the quarters as pos- 

 sible. The nails 

 should be driven 

 where there will be 

 most secure nail- 

 hold; more or less as 

 well as heavier nails 

 being necessary, in 

 proportion to the 

 thickness of the wall, 

 weight of the shoe, 

 and severity of the 



work. The wall is thickest and strongest at the toe or front, and 

 becomes thinner and more flexible toward the quarters and heels, 



especially so at the in- 

 ner heels, where it is 

 sometimes exceedingly 

 thin and flexible. 



By reference to Figs. 

 423, 429, it will be 

 seen that there is con- 

 siderable difference in 

 the breadths and form 

 of the quarters ; that 

 of 423 is most notice- 

 able. The end secured 

 in this part being nar- 

 rower and straighter, 

 is supposed to be the 

 prevention of interfering or striking ; but the narrowness is com- 

 pensated for by the increased height of the wall, for the purpose
