Toss on the surge, and thro the concave dance;
Whirl'd high, conjoin'd, in crystal mountains driven,
Alp over Alp, they build a midway heaven;
Whose million mirrors mock the solar ray,
And give condensed the tenfold glare of day.
As tow'rd the south the mass enormous glides.
And brineless rivers furrow down its sides;
The thirsty sailor steals a glad supply,
And sultry trade winds quaff the boreal sky.

But oft insidious death, with mist o'erstrown,
Rides the dark ocean on this icy throne;
When ships thro vernal seas with light airs steer
Their midnight march, and deem no danger near.
The steerman gaily helms his course along,
And laughs and listens to the watchman's song,
Who walks the deck, enjoys the murky fog,
Sure of his chart, his magnet and his log;
Their shipmates dreaming, while their slumbers last,
Of joys to come, of toils and dangers past.
Sudden a chilling blast comes roaring thro
The trembling shrouds, and startles all the crew;
They spring to quarters, and perceive too late
The mount of death, the giant strides of fate.
The fullsail'd ship, with instantaneous shock,
Dash'd into fragments by the floating rock,
Plunges beneath its basement thro the wave,
And crew and cargo glut the watery grave.

Say, Palfrey, brave good man, was this thy doom?
