As growth of form or momentary glance
In a child's features will recall to mind
The father's with the mother's face combin'd,—
Sweet interchange that memories still enhance:
And yet, as childhood's years and youth's advance,
The gradual mouldings leave one stamp behind,
Till in the blended likeness now we find
A separate man's or woman's countenance:—
So in the Song, the singer's Joy and Pain,
Its very parents, evermore expand
To bid the passion's fullgrown birth remain,
By Art's transfiguring essence subtly spann'd;
And from that song-cloud shaped as a man's hand
There comes the sound as of abundant rain.
