Fragment: Saw'st thou that light? exclaim'd the youth, and paused

Saw'st thou that light? exclaim'd the youth, and paused:
Through yon dark firs it glanced, and on the stream
That skirts the woods it for a moment play'd.
Again, more light it gleam'd,--or does some sprite
Delude mine eyes with shapes of wood and streams,
And lamp far beaming through the thicket's gloom,
As from some bosom'd cabin, where the voice
Of revelry, or thrifty watchfulness,
Keeps in the lights at this unwonted hour?
No sprite deludes mine eyes,--the beam now glows
With steady lustre.--Can it be the moon
Who, hidden long by the invidious veil
That blots the Heavens, now sets behind the woods?
No moon to-night has look'd upon the sea
Of clouds beneath her, answer'd Rudiger,
She has been sleeping with Endymion.
