Which I till then had heard appeared the voice
Of common pleasure: beast and bird, the lamb,
The shepherd's dog, the linnet and the thrush
Vied with this waterfall, and made a song
Which, while I listened, seemed like the wild growth
Or like some natural produce of the air,
That could not cease to be. Green leaves were here;
But 'twas the foliage of the rocks—the birch,
The yew, the holly, and the bright green thorn,
With hanging islands of resplendent furze:
