Thoreau writes in his journal:
There is an old pasture behind E. Wood’s incrusted with the clay-like thallus of the bæomyces which is unexpectedly thin . . . P. M.—To Saw Mill Brook and Smith’s Hill.
The Nepta Glechoma is out under R. Brown’s poles . . . I proceed down the Turnpike . . . That sedum (?) by Tuttle’s is now a foot high . . . I sit on a rock in Saw Mill Brook . . . I leave the woods and begin to ascend Smith’s Hill along the course of the rill . . . Return by Mill Brook Ditch Path . . . The pond, Walden, has risen considerably since the melting.
