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, Dreamed calmly out their dangerous dream, Till wakened by the morning beam;When, dazzled by the eastern glow, Such startler cast his glance below, And saw unmeasured depth around, And heard unintermitted sound, And thought the battled fence so frail, It waved like cobweb in the gale;Amid his senses' giddy wheel, Did he not desperate impulse feel, Headlong to plunge himself below, And meet the worst his fears foreshow?--Thus Ellen, dizzy and astound, As sudden ruin yawned around, By crossing terrors wildly tossed, Still for the Douglas fearing most, Could scarce the desperate thought withstand, To buy his safety with her hand.
