FIG. 89.—PIROUETTE WHEEL
The change from gallop left to gallop right may be demanded in a similar manner, the left leg of the rider and the right rein giving the indications.
The gallops previously described are those in which the pace is true, the only forms in which lie ease and safety.
If the horse be in gallop right (or left) and turns to the left (or right), it is false in the gallop, and may fall.
If the horse has gallop right (or left) in the forehand and gallop left (or right) in the hind quarter, it is in the cross-gallop, which is wrong, and the error should be immediately rectified.
To make the horse take gallop right from the halt, the walk, or the slow trot, the rider should first collect the forces of the animal, apply the left heel, and make a slight upward play with the right rein; when given sufficient freedom, the horse will start off with the legs of the right side leading.
Gallop left will be procured in a similar manner by the use of the right heel and the left rein.
In a slow, measured, regularly cadenced pace, the horse should be ridden in the gallop on straight lines and on circles, the rider being careful that the horse is in the true gallop on the turns.
