Toward some elected point of central rock,

As though, for its sake only, roamed the flock

Of waves about the waste: awhile they mock

With radiance caught for the occasion,—hues

Of blackest hell now, now such reds and blues

As only heaven could fitly interfuse,—

The mimic monarch of the whirlpool, king

O' the current for a minute: then they wring

Up by the roots and oversweep the thing,
