North, east, and south there are reefs and breakers
You would never dream of in smooth weather,
That toss and gore the sea for acres,
Bellowing and gnashing and snarling together;
Look northward, where Duck Island lies, 280
And over its crown you will see arise,
Against a background of slaty skies,
A row of pillars still and white,
That glimmer, and then are gone from sight,
As if the moon should suddenly kiss,
While you crossed the gusty desert by night,
The long colonnades of Persepolis;
Look southward for White Island light,
The lantern stands ninety feet o'er the tide;
There is first a half-mile of tumult and fight, 290
Of dash and roar and tumble and fright,
And surging bewilderment wild and wide,
Where the breakers struggle left and right,
Then a mile or more of rushing sea,
And then the lighthouse slim and lone;
And           the weight of ocean is thrown
Full and fair on White Island head,
A great mist-jotun you will see
Lifting himself up silently
High and huge o'er the lighthouse top, 300
With hands of wavering spray outspread,
Groping after the little tower,
That seems to shrink and shorten and cower,
Till the monster's arms of a sudden drop,
And silently and fruitlessly
He sinks back into the sea.
