152 HORSESHOEING. 



which are the result of improper shortening of the wall and of 

 neglect in horses running barefoot. 



Only the third class of wry hoofs requires especial attention. 

 First, the more oblique wall must be cut down, and the steep 

 wall spared, — a procedure which differs essentially from that 

 employed in treating the first and second classes, but is, never- 

 theless, entirely warranted, because this third kind of wry hoof 

 does not correspond to the direction of the limb. 



In order to take weight from the steep wall, we use with ad- 

 vantage a bar-shoe, and concave the upper surface of the bar 

 underneath the outer branch of the frog (Fig. 131). The con- 

 tracted (steep) wall should neither rest upon the shoe nor be 

 nailed to it ; it should be left wholly free, either by rasping it 

 down or by beating down the upper surface of the correspond- 

 ing branch of the shoe. 



In old work-horses any sort of shoe may be used, though a 

 flat shoe serves the purpose best. If a hoof is wry from faulty 

 paring, and we cannot at once completely restore the proper 

 relative slant of the two walls by paring alone, we may use a 



shoe with a thicker branch for 

 the half of the hoof which is 

 too low (too steep). 



In colts such wry hoofs can 

 often be cured only by shoe- 

 ing. The shoe employed for this 

 purpose is so made that the 

 branch underneath the steep 

 (contracted) wall is quite thick, 

 but gradually thins away around

cases the thin branch may end 

 at the middle of the side wall (a three-quarter shoe). This method 

 of shoeing shifts the body-weight upon the slanting wall and re- 

 stores the foot to its proper shape in from two to four shoeings.
