spurs does not occur at any fixed period, but is given when the occasion presents itself. If the horse is behind the legs (see Question XXVIII), put him at a trot in order to have him securely in motion (not liable to stop), and then let him feel the spurs by vigorous and repeated action until he leaps to the front.
Here it is particularly important to pay attention to the hand; you must not contradict with the hand what you demand with the legs, but must let the reins slip as much as is necessary to enable the horse to extend himself freely.
With certain horses it is sometimes prudent to grasp the pommel of the saddle when giving the spur lesson. The rider is then more certain of not contradicting himself and the lesson thus administered is sure to be profitable in the training of the animal.
