“Now, get below for a sluice and a dram,” cried the cheery voice of the Lieutenant, whose idea of handling a crew was not according to naval instructions. The men trooped down the narrow companion-way laughing and joking in their excitement; but the roar of the enemy’s guns, as he fell round to port, and brought his starboard broadside to bear, was a summons that brought them tumbling on deck again ere they had time to wipe their mouths with a backhanded swipe.

“Steady, men, and to your quarters,” said the Captain quietly; “all but the men for the big gun, who will go below.”

Five men had taken their position about the big gun, which stood with its chase pointing up, as though looking away to the horizon for its enemy. These men stood astonished at the order.

“Below, men,” said Lieutenant Webster, approaching them; “you’ll not be wanted till morning,” he added, as he noted their sidelong looks.

They went down in silence; and, by the pressure of a button in the conning-tower, the Captain lowered the long gun into the deck, the same machinery sliding a heavy shield of toughened steel over the opening left by its disappearance. This gun had been specially built for the catcher, and was of a larger calibre than the guns usually carried by that kind of craft. It rose or fell on a strong powerful lever, on a modified principle used for the disappearing guns; and the frame of the ship had been strengthened amidships to bear the strain. It could be loaded and fought on deck, or loaded below and fired from the conning-tower when at close quarters, and had been christened “The Ghost,” after a trial made before reaching Madeira. “The Ghost” was turned out at the Elswick Works, and could fire sixty fifty-pound projectiles in ten minutes.

“We’ve laid our ghost,” said Webster to Hume, who, being quite fresh to this part of the business, stood looking out into the blackness astern in a state of suspense; “we’ve laid our ghost, and must raise theirs.”

“Is that you, Mr Webster?” said the Captain, leaning over the bridge.

“Yes, sir!”

“I must ask you to go to your cabin.”

“To my cabin, sir?”
