Tracks and Motion of the Feet 



these feet must occur at the same time ; that is, one fore and one hind 

 should touch the ground at the same time. This is eminently so in 

 the true trot and pace. Nor should there be any accent on the fall of 

 one pair more than on the other. In order to bring about this regu- 

 larity the distance of one fore from the other and of one hind from 

 the other, should be the same ; that is, the extension of all four should 

 be equal. And if this is so, then the two distances between the corre- 

 lated feet should be the same. In fact, it will be found that the funda- 

 mental principle of the square trot is the equal distance between these

diagonally opposite feet. The same principle holds good with the dis- 

 tance between the lateral feet, or feet on the two sides of the pacer. 

 These also strike the ground at the same time and must be equally 

 separated for even action and extension. 



In Figs. 10, ii and 12 we shall take a brief look at the positions 

 of the pacer when at rest, in a slow walk and at speed. What 

 is true of the trotter's locomotion is also true of that of the pacer, with 

 some slight modifications. A line pace is not generally spoken of as 

 often as a line trot, but what holds good of lost motion in curves in 

 one gait is also true in the other, and the danger point of interference 

 is similar. As in the trot the hind foot is likely to interfere with the
