HORSESHOEING. 



which fits the coronary band (Fig. 26, /). The lower border of 

 the wall, called the "bearing-edge" ov plantar border (Fig. 27, a), 

 is the one to which the horseshoe is fastened. By dividing a hoof 

 from before to behind along its median line, outer and mner halves 

 or loalls are produced, and by dividing the entire lower circum- 

 ference of the wall into five equal parts or sections, a toe, two 



side walls or marnmse, and 

 ^^^- 2'^- two quarters vrill be exhib- 



^ ' '^ ited (Fig. 27, a, 6, o). In 



order to designate these re- 

 gions of the hoof still more 

 accurately, they are spoken 

 of as outer and inner toes, 

 quarters, and heels. 



The direction (slant) and 

 length of the wall vary in one 

 and the same hoof, as well 

 as between fore and hind 

 hoofs. The toe portion of 

 the wall of fore-hoofs is 

 the most slanting, — that is, 

 forms the most acute angle 

 with the surface of the 

 ground, — and is also the 

 longest. Towards the quar- 

 ters the wall graduahy be- 

 comes very nearly vertical ;

 foot. At the same time the wall, in passing back from the toe to 

 the heel, becomes gradually shorter in such a manner that the 

 heights of the toe, side walls, and quarters are related to one 

 another about as 3 : 2 : 1 in front hoofs, and as 4 : 3 : 2 in hind
