Gait of the American Trotter and Pacer 



This case is a very fine example of the influence of weight on hind 

 feet and of its direction by the shape of the shoe. It is a case where 

 a well developed hind action under ordinary work changed into an ex- 

 cessive hind extension which was not in harmony with front action. 

 From the usual 9 oz. in front and 6 oz. behind, indications suggested 

 the unusual 6 oz. in front and 9 oz. behind. Through it all there was a 

 queer tendency to extend both members of the near side ahead of those 

 on the off side, as if the subject would prefer to pace; but this she 

 never offered to do. The experiments were made in two seasons, the

first one ending as above stated regarding the shoes and the second 

 beginning again on the old plan, but quickly changing to the final de- 

 cision, which not only lengthened her stride, but increased her speed 

 very considerably. 



After a preliminary trial made to get an idea for the next shoeing, 

 she was shod as given in Fig. 150. The near fore had a tendency to 

 toe in so that, while at previous trial the off fore showed 5.5 outward 

 toeing, the near fore showed 3.2 or that much inward toeing. By 

 paring the foot as indicated under the shoe, the near fore at this trial 

 showed o, or a straight direction.
