The brain, the blood, the busy thews
That quickened in the primal ooze
Support me yet; till ice shall grip
The heart of Earth, no strength they’ll lose.

They take my thought, they laugh, they run—
Ere megatherial moons, begun;
And shall, till they shall drop within
The shattering whirlwinds of the sun.

In subtle and essential ways,
Rich with innumerable days,
To mould, to charge, to impel me still,
Each through my broadest being plays.

They surged to this hour, this transfuse—
The brain, the blood, the busy thews;
That act of mine the ultimate stars
Shall look on sprang in primal ooze.
