The single trees and the groves left standing on the interval appeared naturally disposed, though the farmer had consulted only his convenience, for he too falls into the scheme of Nature. Art can never match the luxury and superfluity of Nature. In the former all is seen; it cannot afford concealed wealth, and is niggardly in comparison; but Nature, even when she is scant and thin outwardly, satisfies us still by the assurance of a certain generosity at the roots. In swamps, where there is only here and there an ever-green tree amid the quaking moss and cranberry beds, the bareness does not suggest poverty. The single-spruce, which I had hardly noticed in gardens, attracts me in such places, and now first I understand why men try to make them grow about their houses. But though there may be very perfect specimens in front-yard plots, their beauty is for the most part ineffectual there, for there is no such assurance of kindred wealth beneath and around them, to make them show to advantage. As we have said, Nature is a greater and more perfect art, the art of God; though, referred to herself, she is genius; and there is a similarity between her operations and man's art even in the details and trifles. When the overhanging pine drops into the water, by the sun and water, and the wind rubbing it against the shore, its boughs are worn into fantastic shapes, and white and smooth, as if turned in a lathe. Man's art has wisely imitated those forms into which all matter is most inclined to run, as foliage and fruit. A hammock swung in a grove assumes the exact form of a canoe, broader or narrower, and higher or lower at the ends, as more or fewer persons are in it, and it rolls in the air with the motion of the body, like a canoe in the water. Our art leaves its shavings and its dust about; her art exhibits itself even in the shavings and the dust which we make. She has perfected herself by an eternity of practice. The world is well kept; no rubbish accumulates; the morning air is clear even at this day, and no dust has settled on the grass. Behold how the evening now steals over the fields, the shadows of the trees creeping farther and farther into the meadow, and erelong the stars will come to bathe in these retired waters. Her undertakings are secure and never fail. If I were awakened from a deep sleep, I should know which side of the meridian the sun might be by the aspect of nature, and by the chirp of the crickets, and yet no painter can paint this difference. The landscape contains a thousand dials which indicate the natural divisions of time, the shadows of a thousand styles point to the hour.

"Not only o'er the dial's face,
This silent phantom day by day,
With slow, unseen, unceasing pace
Steals moments, months, and years away;
From hoary rock and aged tree,
From proud Palmyra's mouldering walls,
From Teneriffe, towering o'er the sea,
From every blade of grass it falls."

It is almost the only game which the trees play at, this tit-for-tat, now this side in the sun, now that, the drama of the day. In deep ravines under the eastern sides of cliffs, Night forwardly plants her foot even at noonday, and as Day retreats she steps into his trenches, skulking from tree to tree, from fence to fence, until at last she sits in his citadel and draws out her forces into the plain.
