Fig. 165. Cross-firing is caused 

 by unbalanced feet and improperly 

 constructed shoes. Almost all speed 

 horses require the sharp outside edge 

 of their front shoes to be taken 

 off on the ground surface to pre- 

 vent scalping. By examining and 

 comparing the stride of the cross- 

 firing foot, it will be found that the 

 stride of that member is shorter 

 than its fellow by four to six inches, 

 causing an occasional hitch or hop 

 in the gait. In cases of this kind 

 place a cross-firing shoe like Fig. 

 165 on the short striding foot, to 

 weigh four to six ounces heavier 

 than the one on the opposite foot. 

 Where the horse cross-fires with 

 both hind feet have them shod with 



hoes of equal weight. By lower- 

 ing the inside toe and raising the 



atside heel on the long outside 

 1 ranch of the shoe, the feet will be 

 made to stand wider apart on the 



round and will be thus carried out- 

 \\ard from the body, passing the front 

 I ;et without hitting or bruising the 

 inside ankles or shins. The success 

 of this style of shoe is greatly de- 

 pendent on the good judgment of 

 the shoer.
