I saw by the shadows cast by the inequalities of the clayey sand-bank in the Deep Cut that it was necessary to see objects by moonlight as well as sunlight, to get a complete notion of them. This bank had looked much more flat by day, when the light was stronger, but now the heavy shadows revealed its prominences. The prominences are light, made more remarkable by the dark shadows which they cast.
When I rose out of the Deep Cut into the old pigeon-place field, I rose into a warmer stratum of air, it being lighter. It told of the day, of sunny noontide hours,—an air in which work had been done, which men had breathed. It still remembered the sunny banks,—of the laborer wiping his brow, of the bee humming amid flowers, the hum of insects. Here is a puff of warmer air which has taken its station on the hills; which has come up from the sultry plains of noon.[194]
I hear the nighthawks uttering their squeaking notes high in the air now at nine o’clock p. m., and occasionally—what I do not remember to have heard so late—their booming note. It sounds more as if under a cope than by day. The sound is not so fugacious, going off to be lost amid the spheres, but is echoed hollowly to earth, making the low roof of heaven vibrate. Such a sound is more confused and dissipated by day.
The whip-poor-will suggests how wide asunder [are] the woods and the town. Its note is very rarely heard by those who live on the street, and then it is thought to be of ill omen. Only the dwellers on the outskirts of the village hear it occasionally. It sometimes comes into their yards. But go into the woods in a warm night at this season, and it is the prevailing sound. I hear now five or six at once. It is no more of ill omen therefore here than the night and the moonlight are. It is a bird not only of the woods, but of the night side of the woods.
New beings have usurped the air we breathe, rounding Nature, filling her crevices with sound. To sleep where you may hear the whip-poor-will in your dreams!
I hear from this upland, from which I see Wachusett by day, a wagon crossing one of the bridges. I have no doubt that in some places to-night I should be sure to hear every carriage which crossed a bridge over the river within the limits of Concord, for in such an hour and atmosphere the sense of hearing is wonderfully assisted and asserts a new dignity, and [we] become the Hearalls of the story. The late traveller cannot drive his horse across the distant bridge, but this still and resonant atmosphere tells the tale to my ear. Circumstances are very favorable to the transmission of such a sound. In the first place, planks so placed and struck like a bell swung near the earth emit a very resonant and penetrating sound; add that the bell is, in this instance, hung over water, and that the night air, not only on account of its stillness, but perhaps on account of its density, is more favorable to the transmission of sound. If the whole town were a raised planked floor, what a din there would be!
I hear some whip-poor-wills on hills, others in thick wooded vales, which ring hollow and cavernous, like an apartment or cellar, with their note. As when I hear the working of some artisan from within an apartment.
I now descend round the corner of the grain-field, through the pitch pine wood into a lower field, more inclosed by woods, and find myself in a colder, damp and misty atmosphere, with much dew on the grass. I seem to be nearer to the origin of things. There is something creative and primal in the cool mist. This dewy mist does not fail to suggest music to me, unaccountably; fertility, the origin of things. An atmosphere which has forgotten the sun, where the ancient principle of moisture prevails. It is laden with the condensed fragrance of plants and, as it were, distilled in dews.
The woodland paths are never seen to such advantage as in a moonlight night, so embowered, still opening before you almost against expectation as you walk; you are so completely in the woods, and yet your feet meet no obstacles. It is as if it were not a path, but an open, winding passage through the bushes, which your feet find.
Now I go by the spring, and when I have risen to the same level as before, find myself in the warm stratum again.
