Thoreau writes in his journal:
This morning the fog over the river and the brooks and meadows running into it has risen to the height of forty or fifty feet. 1 P. M.—To river; by boat to Corner Bridge. A very still, warm, bright, clear afternoon. Our [w/ Channing?] boat so small and low that we are close to the water. The muskrats all the way are now building their houses, about two thirds done . . .
