The pupil will find the passage much more easy to execute than the "shoulder in," though, I repeat, no horse would do the former up to the hand as he ought to do unless he has been well drilled in the latter. The greatest care on the part of both master and pupil is indispensable to carry out this lesson. The slightest inadvertence or false movement is at once answered on the part of the horse by his taking advantage of it and putting himself in a wrong position, whereas if he is carefully ridden, and kept well up to the hand, the subsequent cantering lesson will be much more easy to perform. It must be clearly understood, however, that for a lady to attempt to execute the "bending lesson" by written directions alone, and unaided by the vigilant superintendence and oral instruction of a first-rate master would be a mistake. Clear and concise as the language of the "Aid Book" is, it is impossible for any man writing such directions to indicate the precise moment at which each movement of hand and leg is to be made, any more than the man who writes the score in music can regulate the hand of the instrumental executant of it. There must be energy, patience, and close attention on the part of the pupil; vigilance, patience, temper, and thorough knowledge of his craft on the part of the instructor. Master and pupil thus in accord, the latter will derive great advantage and insight into the elegant accomplishment she is endeavouring to acquire, while anything like carelessness on either side will be fatal to the utility of the lesson. It should be thoroughly well done or not at all. After the careful execution of the above lesson, the pupil should prepare her horse for cantering by reigning him back lightly on his haunches; touching him if necessary smartly with her whip, in order to put him well up to his work. A step or two back (_well up to the bridle_) is sufficient, when she should move forward, and the instructor should give her the aids for cantering; which (once more to quote the simple language of the "Aid Book") are as follows: "A light firm feeling of _both_ reins to raise the horse's forehand, a pressure of both legs to keep his haunches under him, a double feeling of the inward rein, and a stronger pressure of the outward leg, will compel the horse to strike off true and united." The above of course is intended as instruction to a man; but substituting a light tap of the whip on the off shoulder for the pressure of the inward leg of the man, and very light for strong aids, the instruction holds good in the case of the lady.
