rid of, not only before the shoe is put on, but before the proper surface 

 can be adapted for it." 



The shoe should, in form and size, little more than cover the 

 wall, excepting at the heels, whei-e it should be so much wider 

 and longer as to compensate 

 for the growth of the foot, 

 and be heavy enough to 

 sustain the attrition, or 

 wear, for the time it is ex- 

 pected to be on. But should 

 this require an excessive 

 thickness, then the bar may 

 be made wider, to permit 

 more wearing surface. It 

 should fit closely all the way 

 around to the bearing sur- 

 face prepared for its recep- 

 tion, so that it may give to 

 the crust all the support it 

 can receive, and carry out in 

 its ground surface, as nearly 

 as possible, the form of the 

 wall before it was cut away. It is a rule, recognized by the best 



authorities, that the sole should 

 not rest upon the shoe, except 

 around the toe where the out- 

 er edge is left full and nat- 

 ^\ ural. But if the wall is cut 

 down close, and the sole rath- 

 er thin (which, as explained 

 |ji"jl before, in no case should be 

 done except for special patho- 

 logical reasons), it is advisa- 

 ble, if it comes too near the 

 iron, to lower the part coming 

 under it. As a rule, the bear- 

 ing surface should be level, 

 and the ground sui-face con- 

 cave, or the inner edge of th^
