Thoreau writes in his journal:
Pink-colored yarrow. Epilobium coloratum, a day or more. Young partridges (with the old bird), as big as robins . . .
The large evening-primrose below the foot of our garden does not open till some time between 6.30 and 8 P.M. or sundown. It was not open when I went to bathe, but freshly out in the cool of the evening at sundown, as if enjoying the serenity of the hour.
