POWDERY DEGENEEATION OP THE DEEP PAETS OP THE WAl.L. 

 SEEDY TOE. 



Ths result of uneven bearing of the shoe, the formation 

 of furrows between the sole and wall, direct violence, aa 

 blows, or the too tight hammering of clips, etc., this is 

 manifested by an irregularity or dryness of the affected 

 part of the wall, and the formation of a cavity, filled with 

 horn powder between the laminae and the wall of the hoof. 

 Clear out the cavity until the tough healthy horn is 

 reached, then fill with warm tar and shoe carefully to give 

 a uniform bearing. A cHp may be useful as a support to

 until the cavity is filled up.
