in Thoreau’s Journal:
P.M. To Assabet bathing place. Found an unusual quantity of Amelanchier berries. I think of the two common kinds, one a taller bush twice as high as my head, with thinner and lighter colored leaves, and larger, or at least somewhat softer, fruit, the other, a shorter bush, with more rigid and darker leaves, and dark blue berries, with often a sort of wooliness on them. Both these are now in their prime. These are the first berries after strawberries, or the first and, I think, the sweetest bush berries, somewhat like high blueberries, but not so hard.
