THE HOKSE AND HIS STBUCTUKE. 



CHAPTER II. 



THE HOOF, SOLE, ETC. 



IF the reader can manage to look at the under surface 

 of a horse's foot that never has been touched by 

 the farrier, he will see that it has the appearance given 

 in illustration (p. 318). It seems to be divided into two 

 parts, the heel portion, looking something like the Broad 

 Arrow of the Government, X/, the Y-like barbs of the 

 arrow forming the "bars of the horny frog," while the 

 projecting rounded portions at the ends of the bars are 

 called the "glumes," or heels of the frog. The outline 

 of the edge of the hoof is beautifully rounded, and the 

 " sole " unites it with the frog, the place where the sole 

 and crust join each other being technically known as the 

 White Line, or Commissure.
