1 82 Gait of the American Trotter and Pacer 



different adjustment of the shoes. Aside from the difference of the 

 off hind shoe noted above, there is only the paring of the hoofs as a 

 cause for the various results. 



In Fig. I43-A and B the angles in front were the same as in Fig. 

 142, that is, 50 and 51 respectively for the near and off fore foot, 

 and behind they were both 55 in A and 55 and 54 in B, as in Fig. 142. 

 This horse always did better with a lower angle on the off hind, on ac- 

 count of its lack of extension, and when that foot had a shoe without 

 swelled heels, as in Fig. 143-6, it responded still better. Again, in Fig. 

 I43-A both front feet were alike in length (3^ in.), but in B the near 

 fore was 3% in. and the off fore 3^8 i n - The lengths of the toes behind 

 were in A: 3^ in. and 3% in. respectively for the near and off hind; 

 and in B : 3^ in. and 3^5 in. for the same feet. The toes in Fig. 142 

 were all around */ in. longer than in Fig. 143-6. This increased lev- 

 erage at the toe no doubt had something to do with the greater varia- 

 tions from the average stride as noted below. The fact remains that 

 the horse trotted remarkably square and true under the conditions of 

 Fig. I43-B. The subsequent adjustment of Fig. 142 was rather an 

 exaggeration of the previous conditions and therefore caused too 

 marked a difference of the extensions. 



The greater stride in the latter case (i8.n ft.) will naturally 

 bring about a greater separation of the extremities, and will show up 

 the effects in a more marked manner. By comparing the total varia- 

 tions of each leg from the average stride we shall again notice the in- 

 fluence of the different adjustments. We have the following:

Here we have the smallest variations in the trial which was trotted 

 best and with the least apparent effort. It should be remembered thtit
