156 'TO RACK AT THE GALLOP. 



the balance of the mass will be destroyed 



and a mishap may ensue. 



The gallop in place is in the true action 

 of the gallop, and the horse is in a high 

 state of equilibrium. But in the so-called 

 gallop to the rear, while the horse must be 

 in perfect equilibrium to begin the move- 

 ment, the forces of the forehand must be 

 carried back too far, and the changes in 

 the points of balance are made too slowly 

 to permit the horse to be always light. 



Of course, the horse must be kept col- 

 lected, and the action of the forehand and 

 of the croup must be kept up in the best 

 equilibrium possible, or the movement must 

 come to an end. But a high state of 

 equilibrium is not constant, though it may 

 be regained when the horse moves forward 

 in the gallop.
