Thoreau writes in his journal:
The black current will not bloom for five or six days. A large red maple just begun to leaf—its keys an inch and a half long—by Assabet Bridge. Castilleja show red,—one,—but will not blook under a week probably. The same of erigeron. Cornus alternifolia and paniculata begin to leaf. Scared up three quails in the stubble in G.M. Barrett’s orchard. . .
