in Thoreau’s Journal:

I sit now on a rock on the west slope of Fair Haven orchard, an hour before sunset, this warm, almost sultry evening, the air filled with the sweetness of apple blossoms (this is blossom week) — or I think it is mainly that meadow fragrance still — the sun partly concealed behind a low cloud in the west, the air cleared by last evening’s thunder-shower, the river now beautifully smooth (though a warm, bland breeze blows up here), full of light and reflecting the placid western sky and the dark woods which overhang it. I was surprised, on turning round, to behold the serene and everlasting beauty of the world, it was so soothing, I saw that I could not go home to supper and lose it. It was so much fairer, serener, more beautiful, than my mood had been.

The fields beyond the river have unexpectedly a smooth, lawn-like beauty, and in beautiful curves sweep round the edge of the woods. The rapidly expanding foliage of the deciduous trees (last evening’s rain or moisture has started them) lights up with a lively yellow green the dark pines which we have so long been used to. Some patches (I speak of woods half a mile or more off) are a lively green, some gray or reddish-gray still, where white oaks stand. With the stillness of the air comes the stillness of the water. The sweetest singers among the birds are heard more distinctly now, as the reflections are seen more distinctly in the water — the veery constantly now. Methinks this serene, ambrosial beauty could hardly have been but for last evening’s thunder-shower, which, to be sure, barely touched us, but cleared the air and gave a start to vegetation. The elm on the opposite side of the river has now a thin but dark verdure, almost as dark as the pines, while, as I have said, the prevailing color of the deciduous woods is a light yellowish and sunny green. The woods rarely if ever present a more beautiful aspect from afar than now. Methinks the black oak at early leafing is more red than the red oak. Ah, the beauty of this last hour of the day — when a power stills the air and smooths all waters and all minds — that partakes of the light of the day and the stillness of the night!
