TO BACK AT THE GALLOP. 69 



movement must come to an end. But 

 a high state of equihbrium is not con- 

 stant, though it may be regained when 

 the horse moves forward in the gallop. 

 I believe that no other writer has 

 given a description of the action of the 

 horse in the movement, and I know 

 that the impression derived from the 

 methods by which it is proposed to pro- 

 duce it is of an action very different 

 from that I have described. I can only 

 say that I have explained the move- 

 ment as I have seen it performed by 

 the horse, and I know of no other way 

 in which the horse can move with 

 lightness to the rear in any action 

 that resembles the gallop.
