The proud, the cold untroubled heart of stone, that never mused on sorrow but its own.

Whose lines are mottoes of the heart,Whose truths electrify the sage.

Britannia needs no bulwarks, No towers along the steep; Her march is o'er the mountain waves, Her home is on the deep.

Ye mariners of England! That guard our native seas; Whose flag has braved a thousand years, The battle and the breeze!

For Beauty's tears are lovelier than her smile.

One moment may with bliss repay Unnumbered hours of pain.
