in Thoreau’s Journal:

Cornus Canadensis just out. Probably the C.florida should be set down to-day, since it just begins to shed pollen and its involucre is more open. It is a fair but cool and windy day, a strong northwest wind, and the grass, to which the rain has given such a start, conspicuously waves, showing its lighter under side, and the buttercups toss in the wind. The pitch and white pines have grown from one to five inches.
