in Thoreau’s Journal:
P. M. – To old mill-site behind Ponkawtasset. Poke berries in the sprout-land east of the red huckleberry still fresh and abundant, perhaps a little past prime. I never saw so many. The plants stand close together, and their drooping racemes three to five inches long, of black or purplish-black berries (ending in red and less [an indecipherable word]), almost crowd one another, hanging around the bright-purple, now for the most part bare, stems.
I hear some birds about, but see none feeding on the berries. I could soon gather bushels there. The arum berries are still fresh and abundant, perhaps in their prime. A large cluster is two and a half inches long by two wide and rather flattish. One, which has ripened prematurely, the stalk being withered and drooping, resembles a very short thick ear of scarlet corn. This might well enough be called snake-corn. These singular vermilion-colored berries, about a hundred of them, surmount a purple bag on a peduncle six or eight inches long. It is one of the most remarkable and dazzling, if not the handsomest, fruits we have. These were by violet wood-sorrel wall. How many fruits are scarlet now! – barberries, prinos, etc. A flock of vireo-like, somewhat yellowish birds, very neat, white beneath and olive above, in garden.
