THE SCIENTIFIC EQUITATION 



that of the "one, two; one, two; lunge'* in fencing. 

 Or, since many riders do not fence, it is very nearly 

 the tick of the second-hand of a watch. At the 

 touch of the left spur, the horse, surprised, raises its 

 left hind leg and moves its body toward the right. 

 Then, at precisely the right instant, comes the right 

 spur to prevent the haunches from swinging to the 

 right, and also to lift the right leg. Then again the 

 left spur with the reversed effect; and so alter- 

 nately. After four such trials, whether successful or 

 not, stop, calm your horse, and begin again. 



The master or the student must impress upon his 

 mind exactly what he desires to obtain and the 

 means by which he is to obtain it. If what has been 

 written above has been studied and understood, it 

 should be clear that the point is to utilize the an- 

 imal's forces in such wise as to secure height at the 

 expense of progress. Evidently, it will be by the op- 

 position of the hand that the motion forward will be 

 checked and converted into motion up. Thus the 

 propulsive force generated by the attacks of the 

 spurs, which tends to drive the horse forward, is re- 

 ceived upon the hand. The fingers close upon the 

 reins just at the instant of the forward push. The 

 result is that the fore leg flexes with the knee up and 

 forward, the foot down. Simultaneously with this, 

 the opposite rear leg comes up, and the horse bal- 

 ances upon a diagonal biped. 



Consider, for example, the first manifestation of 

 the passage on the right lateral biped. We have, in
