Thoreau writes in his journal:
2 P. M.—To Conantum.
A warm, damp, mistling day, without much wind. The white pines in Hubbard’s Grove have now a pretty distinct parti-colored look,—green and yellow mottled,—reminding me of some plants like the milkweed, expanding with maturity and pushing off their downy seeds . . . Sitting by the spruce swamp in Conant’s Grove, I am reminded that this is a perfect day to visit the swamps, with its damp, mistling, mildewy air, so solemnly still . . .
Here was a large hornets’ nest, which when I went to take and first knocked on it to see if anybody was at home, out came the whole swarm upon me lively enough. I do not know why they should linger longer than their fellows whom I saw the other day, unless because the swamp is warmer. They were all within and not working, however. I picked up two arrowheads in the field beyond . . . The mist has now thickened into a fine rian, and I retreat.
