Importance of the straight ahead movement.—Above everything else the horse must go freely straight ahead. The lesson with this object in view must be the first of all lessons; from the beginning of horse training the horse must be accustomed to yield to the action of both legs. This is essentially a sign of docility; the full or the limited obedience of the horse shown in this first test will be an indication of a brief or a protracted period of training.
To accustom the horse to go straight ahead under the action of the legs.—The leg lesson is admittedly the most important lesson, and there is good reason to return to it during the whole period of training. For the first occasion observe the following rules:
Never keep the lower leg glued to the horse's flank, but use repeated taps with the calves.
Tap the horse near the girth and do not reach too far back.
