One thin clear sheet has overleaped and wound
Into this silent depth, which gained, it lies
Still, as but let by sufferance; the trees bend
O'er it as wild men watch a sleeping girl,
And through their roots long creeping plants out-stretch
Their twined hair, steeped and sparkling; farther on,
Tall rushes and thick flag-knots have combined
To narrow it; so, at length, a silver thread,
It winds, all noiselessly through the deep wood
Till through a cleft-way, through the moss and stone,
