t evening, seen not as water, but its surface covered with low
white mist, lying league beyond league in the twilight like a fallen
space of moony cloud; one of Goldau shows the Lake of Zug appearing
through the chasm of a thunder-cloud under sunset, its whole surface one
blaze of fire, and the promontories of the hills thrown out against it,
like spectres; another of Zurich gives the playing of the green waves of
the river among white streams of moonlight: two purple sunsets on the
Lake of Zug are distinguished for the glow obtained without positive
color, the rose and purple tints being in great measure brought by
opposition out of browns: finally, a drawing executed in 1845 of the
town of Lucerne from the lake is unique for its expression of water
surface reflecting the clear green hue of sky at twilight.

Sec. 20. His drawing of falling water, with peculiar expression of weight.

Sec. 21. The abandonment and plunge of great cataracts. How given by him.

It will be remembered that it was said above, that Turner was the only
painter who had ever represented the surface of calm or the _force_ of
agitated water. He obtains this expression of force in falling or
running water by fearless and full rendering of its forms. He never
loses himself and his subject in the splash of the fall--his presence of
mind never fails as he goes down; he does not blind us with the spray,
or veil the countenance of his fall with its own drapery. A little
crumbling white, or lightly rubbed paper, will soon give the effect of
indiscriminate foam; but nature gives more than foam--she shows beneath
it, and through it, a peculiar character of exquisitely studied form
bestowed on every wave and line of fall; and it is this variety of
definite character which Turner always aims at, rejecting, as much as
possible, everything that conceals or overwhelms it. Thus, in the Upper
Fall of the Tees, though the whole basin of the fall is blue and dim
with the rising vapor, yet the whole attention of the spectator is
directed to that which it was peculiarly difficult to render, the
concentric zones and delicate curves of the falling water itself; and it
is impossible to express with what exquisite accuracy these are given.
They are the characteristic of a powerful stream descending without
impediment or break, but from a narrow channel, so as to expand as it
falls. They are the constant form which such a stream assumes as it
descends; and yet I think it
