Many men walk by day; few walk by night. It is a very different season. Take a July night, for instance. About ten o'clock,--when man is asleep, and day fairly forgotten,--the beauty of moonlight is seen over lonely pastures where cattle are silently feeding. On all sides novelties present themselves. Instead of the sun, there are the moon and stars; instead of the wood-thrush, there is the whippoorwill; instead of butterflies in the meadows, fire-flies, winged sparks of fire!--who would have believed it? What kind of cool, deliberate life dwells in those dewy abodes associated with a spark of fire? So man has fire in his eyes, or blood, or brain. Instead of singing-birds, the half-throttled note of a cuckoo flying over, the croaking of frogs, and the intenser dream of crickets,--but above all, the wonderful trump of the bull-frog, ringing from Maine to Georgia. The potato-vines stand upright, the corn grows apace, the bushes loom, the grain-fields are boundless. On our open river-terraces, once cultivated by the Indian, they appear to occupy the ground like an army,--their heads nodding in the breeze. Small trees and shrubs are seen in the midst, overwhelmed as by an inundation. The shadows of rocks and trees and shrubs and hills are more conspicuous than the objects themselves. The slightest irregularities in the ground are revealed by the shadows, and what the feet find comparatively smooth appears rough and diversified in consequence. For the same reason the whole landscape is more variegated and picturesque than by day. The smallest recesses in the rocks are dim and cavernous; the ferns in the wood appear of tropical size. The sweet-fern and indigo in overgrown wood-paths wet you with dew up to your middle. The leaves of the shrub-oak are shining as if a liquid were flowing over them. The pools seen through the trees are as full of light as the sky. "The light of the day takes refuge in their bosoms," as the Purana says of the ocean. All white objects are more remarkable than by day. A distant cliff looks like a phosphorescent space on a hill-side. The woods are heavy and dark. Nature slumbers. You see the moonlight reflected from particular stumps in the recesses of the forest, as if she selected what to shine on. These small fractions of her light remind one of the plant called moon-seed,--as if the moon were sowing it in such places.
