472 HORSESHOEING. 



There are two kinds of quarter-cracks, as 

 shown by plates Nos. 17 and 18 — the lateral 2.nd. 

 the straight the latter being the most serious, if 

 the separation commences at the coronet. 



Treatment. — If the foot is inclined to contract, 

 it should be prepared as for contraction ; shorten 

 the toe and expand the foot, under the directions 

 already given. If lameness has resulted, a bor 

 shoe should be fitted, so as to remove all pres- 

 sure from half an inch on each side of the crack, 

 then w^ith a rasp cut a groove under and parallel 

 with the coronet, extending about half an inch on 

 each side of the crack ; with a shoeing knife cut 

 some small notches on each side of the groove, 

 after which the edges of the crack may be cut 

 away. (See Plates Nos. 17 and 18.) If the 

 foot bleeds freely so much the better. After this 

 is done a firing-iron should be applied so as to 

 cauterize the crack. This operation having been 

 performed, the foot should be dressed with tar 

 every morning for about three weeks. The 

 pressure being removed, the new growth will 

 commence at the coronet, and extend downward,
