The river itself portrays humanity precisely, with its tortuous windings, its accumulation of driftwood, its unsuspected depths, and its crystalline shallows, singing in the Summer sun. Barriers may be built across its path, but they bring only power, as the conquering of an obstacle is always sure to do. Sometimes when the rocks and stone-clad hills loom large ahead, and eternity itself would be needed to carve a passage, there is an easy way around. The discovery of it makes the river sing with gladness and turns the murmurous deeps to living water, bright with ripples and foam.
