 demanding the action as the right fore-leg and 

 its diagonally disposed hind-leg are being brought 

 forward, the impulse being met and turned into 

 action by the hand, the right rein having an upward 

 play to lighten that side, the right spur and the 

 left rein being employed for the action of the 

 other pair of diagonally disposed legs. Of course 

 the equilibrium cannot be maintained in this move- 

 ment ; in fact, the extravagant action is produced 

 by cultivating the side drift of the diagonal strides, 

 that drift which we have so greatly reduced in the 

 passage, and have brought to nothing in the piaff. 



In training Coquette and some other horses, I 

 obtained the extended stride by meeting the im- 

 pulse and by lightening the side of the raised fore- 

 leg with an increased tension of the rein opposite. 

 That is, I used the left heel and the left rein when 

 the right fore-leg was being raised and extended ;
