in Thoreau’s Journal:
On the pitch pine plain at first the pines are far apart––with a wiry grass between & golden rod & hard hack & St. Johns-wort & black-berry vines––each tree nearly keeping down the grass for a space about itself-–meditating to make a forest floor. & here & there younger pines are spring up.
––Further in you come to moss covered patches dry deep white moss––or almost bare mould––half covered with pine needles––
Thus begins the future forest floor.
