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.”

“Then do you think we have nothing more to fear from Fort Sumter?” asked James.

“Nothing at all, but everything from Fort Moultrie, at the end of Sullivan Island; but they will only get a chance at us for half a minute, and then they must choose their time well, and shoot straight if they want to reach us. We are getting near.”

“Right; the position of Fort Moultrie will allow us to go straight for the principal channel. Fire away then, fire away!”

At the same moment, and as if in obedience to James Playfair, the fort was illuminated by a triple line of lightning. A frightful crash was heard; then a crackling sound on board the steamer.
