““I drifted on through the midst of this passionate music and motion, across many a glen, from ridge to ridge; often halting in the lee of a rock for shelter, or to gaze and listen. Even when the grand anthem had swelled to its highest pitch, I could distinctly hear the varying tones of individual trees [...] and even the infinitely gentle rustle of the withered grasses at my feet. Each was expressing itself in its own way, - singing its own song, and making its own peculiar gestures - manifesting a richness of variety to be found in no other forest I have yet seen.””
