in Thoreau’s Journal:
Bluets out on the bank by Tarbell’s spring brook, maybe a day or two.
This was a very warm as well as pleasant day, but at one o’clock there was the usual fresh easterly wind and sea-turn, and before night it grew quite cold for the season. The regularity of the recurrence of this phenomenon is remarkable. I have noticed [it], at least, on the 24th late in the day, the 28th and the 29th about 3 p. m., and to-day at 1 p. M. It has been the order. Early in the afternoon, or between one and four, the wind changes (I suppose, though I did not notice its direction in the forenoon), and a fresh cool wind from the sea produces a mist in the air.
