Matching Quote

"The river ... banks were seven or eight feet high, and densely covered with white and black spruce,—which, I think, must be the commonest trees thereabouts,—fir, arbor-vitæ, canoe, yellow and black birch, rock, mountain, and a few red maples, beech, black and mountain ash, the large-toothed aspen, many civil-looking elms, now imbrowned, along the stream, and at first a few hemlocks also.... The immediate shores were also densely covered with the speckled alder, red osier, shrubby willows or sallow, and the like. There were a few yellow lily pads still left, half-drowned, along the sides, and sometimes a white one. Many fresh tracks of moose were visible where the water was shallow, and the lily stems were freshly bitten off by them."

-Henry David Thoreau
