Thoreau writes in his journal:
Yesterday there was no skating, unless you swept the snow from the ice; but to-day, though there has been no rain nor thaw, there is pretty good skating. Yesterday the water which had flowed, and was flowing, back over the ice on each side of the river and the meadows, a rod or two in width, was merely skimmed over, but last night it froze so that there is good skating there . . .
