Held in cohesion by unresting cells,
Which work they know not why, which never halt,
Myself unwitting where their Master dwells.
I do not bid them, yet they toil, they spin
A world which uses me as I use them;
Nor do I know which end or which begin
Nor which to praise, which pamper, which condemn.
So, like a marvel in a marvel set,
I answer to the vast, as wave by wave
The sea of air goes over, dry or wet,
