In one of these arenas is a large sheet of running water, supplied by a
cataract in the neighbourhood; and I have seen the most beautiful
effects produced by children gliding over and as it were dancing on its
surface. The children are selected from the most graceful and beautiful
of those, who, not having sufficient intellect to learn, give no signs
of making a progress which would fit them for more important
occupations.
These children are taught and _willed_ to move in the most graceful
forms. Joining hands and forming exceedingly beautiful groups, they will
glide over the cascade and over the surface of the agitated lake,
walking, dancing, or reposing.
