Thoreau writes in his journal:
E. Hoar saw the henbit (Lamium amplexicaule) a week ago from Mr. Pritchard’s garden . . . A man is about town with a wagon-load of the Rhododendron maximum this evening from Gardiner, Maine . . . At 5 P. M., dark, heavy, wet-looking clouds are seen in the northern horizon, perhaps over the Merrimack Valley, and we say it is going down the river and we shall not get a drop . . .
