Thoreau writes in his journal:
P.M.—To Walden.
Much pine pollen is washed up on the northwest side of the pond. Must it not have come from pines at a distance. Very hot day, as was yesterday,—98° at 2 P.M., 99° at 3, and 128° in sun. Nighthawks numerously squeak at 5 P.M. . . .
Thoreau also writes to Calvin Greene:
Dear Sir
On the 12 ult I forwarded the two books to California, observing your directions in every particular, and I trust that Uncle Sam will discharge his duty faithfully. While in Worcester this week I obtained the accompanying daguerreotype—which my friends think is pretty good—though better looking than I.
Yrs
Henry D Thoreau
Daniel Ricketson writes in his journal:
Exceedingly warm at Concord. Thermometer at 93 in the shade north side Mr. Thoreau’s house, 12 M., rose to 97; spent the forenoon with Mr. Thoreau, Senr., walked down by the river and sat under the shade of the willows by the bank; walked to Walden Pond with H. D. T. this P. M.; bathed, and crossed the pond with him in a boat we found upon the shore. Saw the Scarlet Tanager by the aid of Thoreau’s glass, a bird I had never seen before . . . R. W. Emerson [Ralph Waldo Emerson] called upon me with evening; talked of Channing [William Ellery Channing] and the Kansas affairs. Walked home with him and with Thoreau. This has been extremely warm, thermometer at 99 at 5 P. M. north side shade of Mr. T.’s house.
