by it on the surface of the smooth lake, will be found to have
been not useless in shaping, by its deposits of gravel and soil
in time of flood, a curve that would not otherwise have existed.
But the more powerful brooks, encroaching upon the level of the
lake, have, in course of time, given birth to ample promontories
of sweeping outline, that contrast boldly with the longitudinal
base of the steeps on the opposite shore; while their flat or
gently-sloping surfaces never fail to introduce, into the midst of
desolation and barrenness, the elements of fertility, even where
the habitations of men may not have been raised."

With this we may contrast, as a companion picture, the poet's
description of the tarns, or lonely bodies of water, which lie here
and there among the hills:

"They are difficult of access and naked; yet some of them
are, in their permanent forms, very grand, and there are accidents
of things which would make the meanest of them interesting.
At all events, one of these pools is an acceptable sight to
the mountain wanderer, not merely as an incident that diversifies
the prospect, but as forming in his mind a centre or conspicuous
