13 August 1860 – 19 August 1860

Heavy rain.

Fair weather. See a blue heron.

2p. mM. — River about ten and a half inches above summer level. Apparently the Canada plum began to be ripe about the 10th.

We have cooler nights of late. See at Pout’s Nest two solitary tattlers, as I have seen them about the muddy shore of Gourgas Pond-hole and in the Great Meadow pools. They seem to like a mud- dier shore than the peetweet. Hear a whip-poor-will sing to-night.

The note of the wood pewee sounds promi- nent of late.

Examine now more at length that smooth, turnip-scented brassica which is a pest in some grain- fields. Formerly in Stow’s land; this year in Warren’s, on the Walden road. To-day I see it in Minot Pratt’s, with the wild radish, which is a paler yellow and a rougher plant. I thought it before the B. campestris, but Persoon puts that under brassicas with siliquis tetraedris, which this is not, but, for aught that appears, it agrees with his B. Napus, closely allied, 2. e. wild rape. Elliot speaks of this as introduced here. Vide Patent Office Report for 1853 and “Vegetable Kingdom,” page 179. The B. campestris also is called rape.' Leersia (cut-grass) abundantly out, apparently several days.
