in Thoreau’s Journal:
P. M. – To Poplar Hill & the Great Fields.
It is still cool weather with a NW wind— There is more shadow in the landscape than a week ago—methinks—& the creak of the cricket sounds cool & steady. The grass & foliage—and landscape generally are of a more thought inspiring color— —suggest what some perchance would call a pleasing melancholy—
In some meadows, as I look southwesterly the aftermath looks a bright yellowish-green—in patches— Both willows & poplars have leaves of a light-color at least beneath—contrasting with most other trees—This weather is a preface to autumn.
