She is a warship, for a narrow pennant floats from her main-mast, and though she is not flying any flag I take her to be an American cruiser.

I wonder whether the _Ebba_ will render her the customary salute as she pa.s.ses.

No; for the schooner suddenly changes her course with the evident intention of avoiding her.

This proceeding on the part of such a suspicious yacht does not astonish me greatly. But what does cause me extreme surprise is Captain Spade's way of manoeuvring.

He runs forward to a signalling apparatus in the bows, similar to that by which orders are transmitted to the engine room of a steamer. As soon as he presses one of the b.u.t.tons of this apparatus the _Ebba_ veers off a point to the south-west.

Evidently an order of "some kind" has been transmitted to the driver of the machine of "some kind" which causes this inexplicable movement of the schooner by the action of a motor of "some kind" the principle of which I cannot guess at.

The result of this manoeuvre is that the _Ebba_ slants away from the cruiser, whose course does not vary. Why should this warship cause a pleasure-yacht to turn out of its way? I have no idea.

But the _Ebba_ behaves in a very different manner when about six o'clock in the evening a second ship comes in sight on the port bow.

This time, instead of seeking to avoid her, Captain Spade signals an order by means of the apparatus above referred to, and resumes his course to the east--which will bring him close to the said ship.

An hour later, the two vessels are only about four miles from each other.

The wind has dropped completely. The strange ship, which is a three-masted merchantman, is taking in her top-gallant sails. It is useless to expect the wind to spring up again during the night, and she will lay becalmed till morning. The _Ebba_, however, propelled by her mysterious motor, continues to approach her.

It goes without saying, that Captain Spade has also begun to take in sail, and the work, under the direction of the boatswain Effrondat, is executed with the same precision and promptness that struck me before.

When the twilight deepens into darkness, only a mile and a half separates the vessels.

Captain Spade then comes up to me--I am standing on the starboard side--and unceremoniously orders me to go below.

I can but obey. I remark, however, ere I go, that the boatswain has not lighted the head-lamps, whereas the lamps of the three-master shine brightly--green to starboard, and red to port.

I entertain no doubt that the schooner intends to pa.s.s her without being seen; for though she has slackened speed somewhat, her direction has not been in any way modified.

I enter my cabin under the impression of a vague foreboding. My supper is on the table, but uneasy, I know not why, I hardly touch it, and lie down to wait for sleep that does not come.

I remain in this condition for two hours. The silence is unbroken save by the water that ripples along the vessel's sides.

My mind is full of the events of the past two days, and other thoughts crowd thickly upon me. To-morrow afternoon we shall reach our destination. To-morrow, I shall resume, on land, my attendance upon Thomas Roch, "if it be necessary," said the Count d'Artigas.

If, when I was thrown into that black hole at the bottom of the hold, I was able to perceive when the schooner started off across Pamlico Sound, I now feel that she has come to a stop. It must be about ten o'clock.

Why has she stopped? When Captain Spade ordered me below, there was no land in sight. In this direction, there is no island until the Bermuda group is reached--at least there is none on the map--and we shall have to go another fifty or sixty miles before the Bermudas can be sighted by the lookout men. Not only has the _Ebba_ stopped, but her immobility is almost complete. There is not a breath of wind, and scarcely any swell, and her slight, regular rocking is hardly perceptible.

Then my thoughts turn to the merchantman, which was only a mile and a half off, on our bow, when I came below. If the schooner continued her course towards her, she must be almost alongside now. We certainly cannot be lying more than one or two cables' length from her. The three-master, which was becalmed at sundown, could not have gone west.

She must be close by, and if the night is clear, I shall be able to see her through the porthole.

It occurs to me, that perhaps a chance of escape presents itself. Why should I not attempt it, since no hope of being restored to liberty is held out to me? It is true I cannot swim, but if I seize a life buoy and jump overboard, I may be able to reach the ship, if I am not observed by the watch on deck.

I must quit my cabin and go up by the forward hatchway. I listen. I hear no noise, either in the men's quarters, or on deck. The sailors must all be asleep at this hour. Here goes.

I try to open the door, and find it is bolted on the outside, as I might have expected.

I must give up the attempt, which, after all, had small chance of success.

The best thing I can do, is to go to sleep, for I am weary of mind, if not of body. I am restless and racked by conflicting thoughts, and apprehensions of I know not what. Oh! if I could but sink into the blessed oblivion of slumber!

I must have managed to fall asleep, for I have just been awakened by a noise--an unusual noise, such as I have not hitherto heard on board the schooner.

Day begins to peer through the gla.s.s of my port-hole, which is turned towards the east. I look at my watch. It is half-past four.

The first thing I wonder is, whether the _Ebba_ has resumed her voyage.

No, I am certain she has not, either by sail, or by her motor. The sea is as calm at sunrise as it was at sunset. If the _Ebba_ has been going ahead while I slept, she is at any rate, stationary now.

The noise to which I referred, is caused by men hurrying to and fro on deck--by men heavily laden. I fancy I can also hear a similar noise in the hold beneath my cabin floor, the entrance to which is situated abaft the foremast. I also feel that something is sc.r.a.ping against the schooner's hull. Have boats come alongside? Are the crew engaged in loading or unloading merchandise?

And yet we cannot possibly have reached our journey's end. The Count d'Artigas said that we should not reach our destination till this afternoon. Now, I repeat, she was, last night, fully fifty or sixty miles from the nearest land, the group of the Bermudas. That she could have returned westward, and can be in proximity to the American coast, is inadmissible, in view of the distance. Moreover, I have reason to believe that the _Ebba_ has remained stationary all night. Before I fell asleep, I know she had stopped, and I now know that she is not moving.

However, I shall see when I am allowed to go on deck. My cabin door is still bolted, I find on trying it; but I do not think they are likely to keep me here when broad daylight is on.

An hour goes by, and it gradually gets lighter. I look out of my porthole. The ocean is covered by a mist, which the first rays of the sun will speedily disperse.

I can, however, see for a half a mile, and if the three-masted merchantman is not visible, it is probably because she is lying off the other, or port, side of the _Ebba_.

Presently I hear a key turned in my door, and the bolts drawn. I push the door open and clamber up the iron ladder to the deck, just as the men are battening down the cover of the hold.

I look for the Count d'Artigas, but do not see him. He has not yet left his cabin.

Aft, Captain Spade and Engineer Serko are superintending the stowing of some bales, which have doubtless been hoisted from the hold. This explains the noisy operations that were going on when I was awakened.

Obviously, if the crew are getting out the cargo, we are approaching the end of our voyage. We are not far from port, and perhaps in a few hours, the schooner will drop anchor.

But what about the sailing ship that was to port of us? She ought to be in the same place, seeing that there has been and is no wind.

I look for her, but she is nowhere to be seen. There is not a sail, not a speck on the horizon either east, west, north or south.

After cogitating upon the circ.u.mstance I can only arrive at the following conclusion, which, however, can only be accepted under reserve: Although I did not notice it, the _Ebba_ resumed her voyage while I slept, leaving the three-master becalmed behind her, and this is why the merchantman is no longer visible.

I am careful not to question Captain Spade about it, nor even Engineer Serko, as I should certainly receive no answer.

Besides, at this moment Captain Spade goes to the signalling apparatus and presses one of the b.u.t.tons on the upper disk. Almost immediately the _Ebba_ gives a jerk, then with her sails still furled, she starts off eastward again.

Two hours later the Count d'Artigas comes up through the main hatchway and takes his customary place aft. Serko and Captain Spade at once approach and engage in conversation with him.

All three raise their telescopes and sweep the horizon from southeast to northeast.

No one will be surprised to learn that I gaze intently in the same direction; but having no telescope I cannot distinguish anything.

The midday meal over we all return on deck--all with the exception of Thomas Roch, who has not quitted his cabin.

Towards one o'clock land is sighted by the lookout man on the foretop cross-tree. Inasmuch as the _Elba_ is bowling along at great speed I shall soon be able to make out the coast line.

In effect, two hours later a vague semicircular line that curves outward is discernible about eight miles off. As the schooner approaches it becomes more distinct. It is a mountain, or at all events very high ground, and from its summit a cloud of smoke ascends.
