acing this tube
upon the piers has been assimilated to that of raising the Arcade upon
the summit of the spire of St. James's Church, if surrounded with water.

Each line of tube is 1513 feet in length; far surpassing in size any
piece of wrought-iron work ever before put together; and its weight is
5000 tons, being nearly equal to that of two 120-gun ships, having on
board, ready for sea, guns, provisions, and crew. The plate-iron
covering of the tubes is not thicker than the hide of an elephant, and
scarcely thicker than the bark of an oak-tree; whilst one of the large
tubes, if placed on its end in St. Paul's churchyard, would reach 107
feet higher than the cross of the cathedral.

THE MARINERS OF ENGLAND.

Ye mariners of England!
Who guard our native seas,
Whose flag has braved a thousand years
The battle and the breeze,
Your glorious standard launch again,
To match another foe,
And sweep through the deep
While the stormy tempests blow;
While the battle rages long and loud,
And the stormy tempests blow.

The spirits of your fathers
Shall start from every wave!
For the deck it was their field of fame,
And Ocean was their grave;
Where Blake and mighty Nelson fell,
Your manly hearts shall glow,
As ye sweep through the deep,
While the stormy tempests blow;
While the battle rages long and loud,
And the stormy tempests blow.

Britannia needs no bulwarks,
No towers along the steep;
Her march is o'er the mountain waves,
Her home is on the deep:
With thunders from her native oak,
She quells the floods below,
As they roar on the shore,
When the stormy tempests blow;
When the battle rages long and loud,
And the stormy tempests blow.

The meteor-flag of England
Shall yet terrific burn,
Till danger's troubled night depart,
And the star of peace return.
Then, then, ye ocean-warriors!
Our song and feast shall flow
To the fame of your name,
When the storm has ceased to blow;
When the fiery fight is heard no more,
And the storm has ceased to blow.

CAMPBELL.
