Thoreau writes in his journal:
Concord River has a high, and hard bank at its mouth, maybe thirty feet high on the east side; and my host thinks it was o1igirnally about as high on the west side, where now it is much , lower and flat, having been dug down. There is a small isle in the middle of the mouth . . .
Thoreau gives two lectures, “Walking” and “Life Misspent” at Welles Hall in Lowell, Mass. (“Walking“; “Life Misspent“).
