ing, as the effect of such an adjustment became more pronounced; but 

 enough, at any rate, had been shown to warrant the plan of shoeing 

 gradually evolved from the various trials. 



Let us briefly consider the evolution of the gait due to various 

 adjustments intended to regulate it. Without a plan based on previous 

 facts, we could not logically bring about an improvement. We must, 

 therefore, resort to a method by which we can establish comparisons 

 in order to see clearly the effect of all changes made. Even if such a 

 method as this is not followed out in every detail, the main principles

 many disappointments and useless efforts when the whole matter of 

 balance is left to guess work and its rough estimates. 



In Pig. 143 we have a comparative representation of such an evo- 

 lution of the extensions. The extensions given were the results of 

 two trials made between those of Fig. 140 and Fig. 142. The shoes 

 worn in Fig. I43-A and in Fig. 142 were alike, and those of Fig. 

 I43-B were also the same with the exception of off hind, which had 

 no swelled heels. The comparisons of these trials will illustrate what 

 can be done merely by the paring of the hoof. Given, therefore, a 

 set of shoes, it is in our power to vary the movements of a gait by a
