physical and moral, also enters very seriously into the problem.
In the preceding work of the flexions and the mobilizations, the cavalier has used the effects of hands and legs separately. But to obtain the state of equilibrium by means of the assemblage, he must employ hands, legs, and weight, together. This action is often called "effects of ensemble" since it requires the equalization of the forces of the horse, not only to support its own weight, whether at rest or in motion, but also to carry the added weight of the rider, and is brought about by accordant effects of the cavalier.
In short, the separate effects make possible the effects of ensemble. These effects of ensemble produce assemblage. The assemblage gives the state of equilibrium, which is the equal balance of the entire mechanism.
From the beginning of equitation, this state of equilibrium of rider and horse has been the subject of researches and theories, more or less practical. Of these, Baucher's is the most reasonable. Moreover, this grand master has proved experimentally the existence of this equilibrium, and the fact that it is produced by the assemblage. I give here one of Baucher's tests in the form in which I have several times repeated them for myself.
An ordinary saddle horse, properly trained but not practiced in the demonstration, weighs one thousand pounds. I place him, without saddle or
