There are who have, at midnight hour,

In slumber scaled a dizzy tower,

And, on the verge that beetled o’er

The ocean tide’s incessant roar,

Dream’d calmly out their dangerous dream,

Till waken’d by the morning beam;

When, dazzled by the eastern glow,

Such startler[154] cast his glance below,

And saw unmeasured depth around,

And heard unintermitted sound,
