produce a powerful one, is very great. We are never to look for
great intellectuality in a professor of gymnastics, nor to expect
that the time will come when a man will not only walk a thousand
miles in a thousand hours, but compose a poem of a thousand lines
at the same time.

If the temporary diversion of the nervous energy from the brain
have this effect, what must a permanent diversion accomplish? It
will accomplish precisely what is indicated by the look and
language of our two young friends at the station-house. It will
develop muscle for the uses of a special calling, and make ugly
and clumsy men of those who should be symmetrical; and at the same
time it will repress mental development, and permanently limit
mental growth--at least, so long as the mind shall be associated
with the body. I suppose that every fecundated germ of human being
is endowed with a certain possibility of development--a
complement of vital energy which will be expended in various
directions, according to the circumstances which may surround it
and the will of its possessor. If it shall be mainly expended upon
the growth and sustentation of muscle, it will not be expended
upon the growth and sustentation of mind; and I have no hesitation
in saying that it is an absolute impossibility for a man who
engages in hard bodily labor every day to be brilliant in
intellectual manifestation. The tide of such a man's life does not
set in that direction. An hourglass has in it a definite quantity
of sand; and when I turn it over, that sand falls from the upper
apartment into the lower; and while it occupies that position it
will continue to fall until the former is exhausted and the latter
is filled. Moreover, it will never take its place at the other end
of the instrument, until it is turned back. It is precisely thus
