 niav be removed with a blunt instrument. 



■1. The bars should not b;' cut away; they are a part of the 

 wall and intended to carry weight. The shoe should rest on 

 them. 



5. The frog should not be cut, but left to attain its full 

 growth. No frog can perform its functions unless on a level 

 with the ground surface of the shoe. 



6. The shoe should have a true and level bearing and rest 

 well and firmly on the wall and bars. 



A i)lain light-weight shoe is the best — plain on both ground 

 and foot surface. 



7. TTigh nailing is injurious; do not use any more nails than 

 are absolutely necessary, as the nails destroy the horn.
