f course with our condition and the state of the surrounding
circumstances; the second with the amount and kind of power, and the
extent and kind of action. In all forms of active exercise there are
three powers simultaneously in action,--the will, the muscles, and the
intellect. Each of these predominates in different kinds of exercise.
In walking, the will and muscles are so accustomed to work together
and perform their task with so little expenditure of force, that the
intellect is left comparatively free. The mental pleasure in walking,
as such, is in the sense of power over all our moving machinery. But in
riding, I have the additional pleasure of governing another will, and my
muscles extend to the tips of the animal's ears and to his four hoofs,
instead of stopping at my hands and feet. Now in this extension of
my volition and my physical frame into another animal, my tyrannical
instincts and my desire for heroic strength are at once gratified. When
the horse ceases to have a will of his own and his muscles require no
special attention on your part, then you may live on horseback as Wesley
did, and write sermons or take naps, as you like. But you will observe,
that, in riding on horseback, you always have a feeling, that, after
all, it is not you that do the work, but the animal, and this prevents
the satisfaction from being complete.

Now let us look at the conditions of rowing. I won't suppose you to be
disgracing yourself in one of those miserable tubs, tugging in which is
to rowing the true boat what riding a cow is to bestriding an Arab. You
know the Esquimaux _kayak_, (if that is the name of it,) don't you? Look
at that model of one over my door. Sharp, rather?--On the contrary, it
is a lubber to the one you and I must have; a Dutch fish-wife to
Psyche, contrasted with what I will tell you about.--Our boat, then, is
something of the shape of a pickerel, as you look down upon his back,
he lying in the sunshine just where the sharp edge of the water cuts in
among the lily-pads. It is a kind of a giant _pod_, as one may say,--
tight everywhere, except in a little place in the middle, where you sit.
Its length is from seven to ten yards, and as it is only from sixteen to
thirty inches wide in its widest part, you understand why you want those
"outriggers," or projecting iron frames with the rowlocks in which the
oars play. My rowlocks are five feet apart; double or more than double
the greatest width of the boat
