Experiments and their Verification 2 1 1 



the most active foot and the square toe, together with the consequent 

 higher action caused by same, and the influence of the higher elevation 

 of its correlated near fore, increased the greater extension of the off 

 hind. It is noteworthy that the effect of near fore on off hind is 

 neither in this nor in the previous shoeing as great or at all as visible 

 as was the effect on the fore by the hind, as illustrated in previous 

 shoeings. 



B. LONGER HEELS ON HIND SHOES WITH AND WITHOUT SQUARED 



TOES. 



The squaring of the toe of the shoe, other things being equal, has 

 the effect of a readier leverage at the toe and a shorter time-contact 

 with the ground ; and it makes the foot more responsive to the influ- 

 ence of weight and of angle of toe. If one foot only is squared at 

 either or both extremities, its elevation will be increased and its ex- 

 tension will be, as a rule, somewhat checked, much depending on the 

 difference of angle, of weight of the shoe and of length of toe, as com- 

 pared with the other foot. 



In all of these experiments erroneous corrections are bound to 

 appear as judged by a better or worse extension -of correlated feet. 

 The combinations possible to make are very numerous, and therefore 

 are apt to lead to error unless the results are critically compared. 

 After eliminating the error so made, there will still be ample facts left 

 to establish certain general deductions and rules which, when care- 

 fully applied, will yield the corrections for a defective gait. 



Squaring the toes of correlated feet has often led to the straight- 

 ening out of equine locomotion. Another direct effect on hind ex- 

 tension is brought about by comparatively longer heels of shoe on one 

 hind foot only ; and such effect will also be shown in some of the ex- 

 periments offered here. 



Fig. 162 gives a modification of the shoeings of Fig. 160 and Fig. 

 161, principally in regard to weight and angle. A comparatively longer 

 heel on near hind proves to have the effect in this case, as well as in 

 others, to increase forward extension. We shall for the present deal
