Action now shrouds, nor shows the informing thought;
Man, like a glass ball with a spark a-top,
Out of the magic fire that lurks inside,
Shows one tint at a time to take the eye:
Which, let a finger touch the silent sleep,
Shifted a hair's-breadth shoots you dark for bright,
Suffuses bright with dark, and baffles so
Your sentence absolute for shine or shade.
Once set such orbs,—white styled, black stigmatized,—
A-rolling, see them once on the other side
