Thoreau writes in his journal:
P.M.—To Cliffs and Fairhaven . . . Saw the first lark rise from the railroad causeway and sail on quivering wing over the meadow to alight on a heap of dirt. Was that a mink we saw at the Boiling Spring? . . . Fair Haven Pond is nearly half open… It is a rare lichen day . . . Looking behind the bark of a dead white pine, I find plenty of small gnats quite lively and ready to issue forth as soon as the sun comes out.
Concord, Mass. William Ellery Channing writes in his journal:
1st M. Lark. [meadowlark] Insects under bark of an old pine. Chickadees. Fairhaven half open, Wald closed. Lichens in Iron-spring swamp (William Ellery Channing notebooks and journals. Houghton Library, Harvard University).
