To A Thunder-Cloud.

Oh, melancholy fragment of the night
Drawing thy lazy web against the sun,
Thou shouldst have waited till the day was done
With kindred glooms to build thy fane aright,
Sublime amid the ruins of the light!
But thus to shape our glories one by one
With fearful hands, ere we had well begun
To look for shadows--even in the bright!
Yet may we charm a lesson from thy breast,
A secret wisdom from thy folds of thunder:
There is a wind that cometh from the west
Will rend thy tottering piles of gloom asunder,
And fling thee ruinous along the grass,
To sparkle on us as our footsteps pass!
