AND SCHOOL A HORSE. 23 



ward to such a point that they meet and 

 balance the forces of the fore-hand, the 

 horse is in equilibrium, and no movement 

 can be generated until one or other of 

 the forces predominate. 



As the legs act upon the forces of the 

 croup, and as the hand governs the forces 

 of the fore-hand, it will be seen that this 

 union and balance of the forces puts the 

 immediate and distinct control of the 

 mass within the power of the rider. 



The forward movement of the horse 

 will be measured by the effect of the 

 forces of the croup to predominate, 

 and the corresponding yielding of the 

 forces of the fore-hand. 



But if the force opposite the aug- 

 mented force does not yield, then that 

 unyielding part is the more firmly fixed
