Therefore does the reasoned equitation accept as sine qua non the two basal principles, "straight" and "forward." Indeed, if the horse is not straight, it cannot go forward, but advances in the direction in which the spine points. Then are the steps and strides not equal, the coupling yields more to one side than to the other, and carries with it the pelvis, the haunches, and the hind legs. On the other hand, when the spinal column is straight, the coupling gives equally, the pelvis becomes the center for the motion of the two hind legs, the fore and hind parts of the body act in unison, collection and assemblage become possible, and, equilibrium being secured, the center of gravity finds its natural place in the medial plane. In this condition, strides, steps, and gaits become equal and square, the horse suffers less fatigue and wear, and continues in the best condition to develop its natural and instinctive forces.
Very few riders, amateurs or masters, are able to put a horse exactly straight, and to keep it so while they carry it forward or backward. Yet nothing whatever can be done properly by a horse which is not straight.
