"Are you doing all you can in the engine room, Mr. Sampson?" asked Christy, pausing at the engine hatch.

"Everything, Captain Passford, and I think we must be making sixteen knots," replied the chief engineer.

"Is Mr. Bockburn on duty?"

"He is, sir; and if he were a Connecticut Yankee he could not do any better, or appear to be any more interested."

"He seems to be entirely impartial; all he wants is his pay, and he is as willing to be on one side as the other if he only gets it," said Christy. "Has any damage been done to the engine?"

"None at all, sir; a shot from one of those broadside guns went through the side, and passed just over the top of one of the boilers," replied the engineer. "Bockburn plugged the shot hole very skilfully, and said it would not be possible for a shot to come in low enough to hit the boilers. He knows all about the other two vessels, and has served as an engineer on board of the Arran on the other side of the Atlantic."

Just at that moment a shot from the Arran struck the bridge and a splinter from the structure knocked two men over. One of them picked himself up, but said he was not much hurt, and refused to be sent below. The other man was Veering; he seemed to be unable to get up, and was carried down by order of the boatswain. This man was one of the adherents of Hungerford and Pawcett, though so far he had been of no service to them.

Christy hastened forward to ascertain the extent of the damage done to the bridge. It was completely wrecked, and was no longer in condition to be occupied by an officer. But the pilot house was still in serviceable repair, and the quartermaster had not been disturbed. By this time, the Ocklockonee had obtained a position on the port bow of the Arran, and the commander directed the quartermaster at the wheel to run directly for the other side of the enemy.

The time for decisive and final action had come. Mr. Baskirk placed the boarders in position to be thrown on board of the Arran. He was to command the first division himself, and Mr. Amblen the second. The Ocklockonee was rushing at all the speed she could command to the work before her.
