A few minutes later the two screws carried the steamer towards the principal channel, away from Fort Sumter.

"Mr. Mathew," said James, "we must not think of taking the Sullivan Island channel; we should run directly under the Confederate guns. Let us go as near as possible to the right side of the harbour out of range of the Federal batteries. Have you a safe man at the helm?"

"Yes, Captain."

"Have the lanterns and the fires on deck extinguished; there is a great deal too much light, but we cannot help the reflection from the engine-rooms."

During this conversation the Dolphin was going at a great speed; but in altering her course to keep to the right side of the Charleston Harbour she was obliged to enter a channel which took her for a moment near Fort Sumter; and when scarcely half a mile off all the guns bearing on her were discharged at the same time, and a shower of shot and shell passed in front of the Dolphin with a thundering report.

"Too soon, stupids," cried James Playfair, with a burst of laughter. "Make haste, make haste, Mr. Engineer! We shall get between two fires."

The stokers fed the furnaces, and the Dolphin trembled all over with the effort of the engine as if she was on the point of exploding.

At this moment a second report was heard, and another shower of balls whizzed behind the Dolphin.

"Too late, stupids," cried the young Captain, with a regular roar.

Then Crockston, who was standing on the poop, cried, "That's one passed. A few minutes more, and we shall have done with the Rebs."
