Captain Afleck could not keep back a laugh. The boy seemed so deeply concerned about his perplexities whenever he stopped to think of them, although he could forget them so completely when something else engaged his mind.

"Keep your heart up, Terry," he said, in a cheering tone. "We're on a losin' tack now seemingly, but we may 'bout ship soon. Come along with me and see if they won't give us some breakfast."

They found a ready welcome at one of the sailors' messes, and a big piece of bread washed down with steaming coffee perceptibly lightened Terry's spirits, for the time being at all events.

All that day and the next the Minnesota maintained her strenuous speed; and as the afternoon wore on, the signs of bustle and excitement on board, and the earnest way in which the men talked together, showed that they were rapidly nearing their destination.

The approach of battle is a serious enough matter when the forces on both sides are pretty well known, and the character of the undertaking can be at least measurably estimated; but it is a very different matter when neither of these things is known, and when the affair is very much of a leap in the dark.

Now this was just the state of things on the Minnesota. No one on board, not even her captain, had any clear knowledge of the perils and difficulties to be encountered. The Confederate naval force might be found overwhelmingly strong or miserably weak. Moreover, there were certain disturbing rumours afloat about an alarming novelty, in the way of a naval monster, against which no wooden vessel would have the slightest chance. Of this mystery the Norfolk navy-yard still held the secret, although it was generally believed to be about ripe for revelation.

CHAPTER VI.

IN HAMPTON ROADS.

To make entirely clear the position of the Minnesota at this point, some words of explanation are necessary here. The American Civil War was raging hotly, with the advantage if anything on the side of the Southern Confederacy. In the spring of the year 1861, the Federal forces had hurriedly abandoned their great naval establishment at Norfolk in the State of Virginia, why or wherefore it would be hard to say; for they had completed an effective blockade of Hampton Roads, and might have held their ground against all the forces likely to attack them.
