Young as she is, the stuff
Of her life is a great cargo, and some of it heavy:
I wish her a lucky passage.

As if to reject my thought and its easy figure.

The whole house seems to be thinking,
And then she is at it again with a bunched clamor
Of strokes, and again is silent.

Which was trapped in that very room, two years ago;
How we stole in, lifted a sash
And retreated, not to affright it;
And how for a helpless hour, through the crack of the door,
We watched the sleek, wild, dark
And iridescent creature
