Thoreau writes in his journal:
At 6 P.M. 91º, the hottest yet, though a thunder-shower has passed northeast and grazed us, and, in consequence, at 6.30 or 7, another thunder-shower comes up from the southwest and there is a sudden burst from it with a remarkably strong, gusty wind, and the rain for fifteen minutes falls in a blinding deluge . . .
