Gait of the American Trotter and Pacer 



fluenced by right fore and by the two ounces more in weight of shoe 

 the left hind advances slightly in extension, making a greater ex- 

 tension by a fraction of an inch ; and compared with previous trial it 

 advances over the right hind by 0.18 + 0.12 inch or 0.3 inch. All such 

 small differences are negligible and are only given as actual differences 

 of averages of 20 strides. No matter how small, they are nevertheless 

 exact indications of conditions.

To show the effect of the swelled outside heel of the left hind shoe 

 the comparative lateral extensions and angles of feet with reference 

 to the median line are given in Fig. 115. 



The left hind by means of this outside swelled heel is forced to a 

 greater angle, thus showing the effect of the shape of the shoe, besides 

 indicating a greater spread of hind feet by about Y^ inch on the average 

 of 16 strides. It will also be noticed that the fore travel on practically 

 the same line in both trials. In the first trial they cross over, and this 

 is due to the fact that the animal carried her head a little to left side, 

 thus giving the right and paddling fore a chance to land on the 

 inside of its natural line of motion.
