Thoreau writes in his journal:
At Fair Haven Pond I see, half a mile off, eight large water-fowl, which I thought at first were large ducks, though their necks appeared long . . .
Viola ovata on bank above Lee’s Cliff. Edith Emerson found them there yesterday; also columbines and the early potentilla April 13th!!! . . .
Afterwards, along the wall under the Middle Conantum Cliff, I saw many goldfinches, male and female, the males singing in a very sprightly and varied manner, sitting still on bare trees . . .
