Thoreau writes in his journal:
This dog-day weather I can see the bottom where five and a half feet deep. At five feet it is strewn clear across with sium, heart-leaf, Ranunculus Parshii, etc. It is quite green and verdurous, especially with the first. I see the fishes moving leisurely about amid the weeds, their affairs revealed . . .
P.M.—Left boat at Rice’s Bend. I spoke to him of the clapper rail . . .
Thoreau also writes to William A. Wilson:
Dear Sir,
I send you by the same mail with this a copy of A Week on the Concord & Merrimack Rivers. The price in $1.25. The change can be sent in postage stamps. I have no copies of “Walden” to spare; and I learn that it is out of print.
Yours respectfully
Henry D. Thoreau
P.S. These are the only books I have published.
