To suggest the ordinary appearance of calm water, to lay on canvas as much evidence of surface and reflection as may make us understand that water is meant, is, perhaps, the easiest task of art; and even ordinary running or falling water may be sufficiently rendered, by observing careful curves of projection with a dark ground, and breaking a little white over it, as we see done with judgment and truth by Ruysdael. But to paint the actual play of hue on the reflective surface, or to give the forms and fury of water when it begins to show itself; to give the flashing and rocket-like velocity of a noble cataract, or the precision and grace of the sea wave, so exquisitely modelled, though so mockingly transient, so mountainous in its form, yet so cloudlike in its motion, with its variety and delicacy of colour, when every ripple and wreath has some peculiar passage of reflection upon itself alone, and the radiating and scintillating sunbeams are mixed with the dim hues of transparent depth and dark rock below--to do this perfectly is beyond the power of man; to do it even partially has been granted to but one or two, even of those few who have dared to attempt it.... The fact is that there is hardly a road-side pond or pool which has not as much landscape _in_ it as above it. It is not the brown, muddy, dull thing we suppose it to be; it has a heart like ourselves, and in the bottom of that there are the boughs of the tall trees, and the blades of the shaking grass, and all manner of hues of variable pleasant light out of the sky. Nay, the ugly gutter, that stagnates over the drain-bars in the heart of the foul city, is not altogether base; down in that, if you will look deep enough, you may see the dark serious blue of far-off sky, and the passing of pure clouds. It is at your own will that you see in that despised stream either the refuse of the street, or the image of the sky. So it is with almost all other things that we unkindly despise.

THE MOUNTAIN GLORY[72] The best image which the world can give of Paradise is in the slope of the meadows, orchards, and corn-fields on the sides of a great Alp, with its purple rocks and eternal snows above; this excellence not being in any wise a matter referable to feeling, or individual preferences, but demonstrable by calm enumeration of the number of lovely colours on the rocks, the varied grouping of the trees, and quantity of noble incidents in stream, crag, or cloud, presented to the eye at any given moment.
