Thoreau writes in his journal:
The river is considerably raised and also muddied by the recent rains.
I saw a red squirrel run along the bank under the hemlocks with a nut in its mouth. He stopped near the foot of a hemlock, and, hastily pawing a hole with his fore feet, dropped the nut, covered it up, and retreated part way up the trunk of the tree, all in a few moments. I approached the shore to examine the deposit, and he, descending betrayed no little anxiety for his treasure and made two or three motions to recover the nut before he retreated . . .
