The horse-chestnut and mountain-ash leafing.

May 6. 

To Clamshell by river. 

Our earliest currant out. Oat spawn showing little pollywogs (?) in meadow water. 

The horse-chestnut and mountain-ash leafing.

Knawel out at Clamshell; how long? Cerastium out there under the bank. That early white birch there has about done running sap. 

Equisetum sylvaticum a day or two on the ditch bank there.

H. D. Thoreau, Journal, May 6, 1856

See May 6, 1855 ("Equisetum sylvaticum, probably yesterday or day before.”)

Oat spawn. See May 4, 1858 (“What I have heretofore called the oat spawn, . . . is not black and white, like that of the Rana halecina, sylvaltica, and palustris,. . . but a pale brown or fawn-color.”)
