Thoreau writes in his journal:
2.30 P.M.—To Lee’s Cliff on foot.
A still, warm, overcast clay with a southwest wind (this is what the Indians made so much of), and the finest possible dew-like rain in the air from time to time, now more of the sun. It is now so warm that I go back to leave my greatcoat for the first time, and the cooler smell of possible rain is refreshing . . .
9 P.M.—Quite a heavy thunder-shower,—the second lightning, I think.
The vivid lightning, as I walk the street, reveals the contrast between day and night. The rising cloud in the west makes it very dark and difficult to find my way . . .
