As for the little river itself, it has so many beauties that one does not think of asking whether it has any faults. Constant fulness, and crystal clearness, and refreshing coolness of living water, pale green like the jewel that is called aqua marina, flowing over beds of clean sand and bars of polished gravel, and dropping in momentary foam from rocky ledges, between banks that are shaded by groves of fir and ash and poplar, or through dense thickets of alder and willow, or across meadows of smooth verdure sloping up to quaint old-world villages--all these are features of the ideal little river.
