Proserpinaca palustris, spear-leaved proserpinaca, mermaid-weed. (This in Hubbard’s Grove on my way to Conantum.) A hornets’ (?) nest in a rather tall huckleberry bush, the stems projecting through it, the leaves spreading over it. How these fellows avail themselves of the vegetables! They kept arriving, the great fellows, but I never saw whence they came, but only heard the buzz just at the entrance. (With whitish abdomens.) At length, after I have stood before the nest five minutes, during which time they had taken no notice of me, two seemed to be consulting at the entrance, and then one made a threatening dash at me and returned to the nest. I took the hint and retired. They spoke as plainly as man could have done.
