It only remained for them, therefore, to take leave of the Count d'Artigas.

"You must pardon us for having disturbed you, Monsieur the Count,"

said the lieutenant.

"You were compelled to obey your orders, gentlemen."

"It was merely a formality, of course," ventured the officer.

By a slight inclination of the head the Count signified that he was quite willing to accept this euphemism.

"I a.s.sure you, gentlemen, that I have had no hand in this kidnapping."

"We can no longer believe so, Monsieur the Count, and will withdraw."

"As you please. Is the _Ebba_ now free to proceed?"

"Certainly."

"Then _au revoir_, gentlemen, _au revoir_, for I am an _habitue_ of this coast and shall soon be back again. I hope that ere my return you will have discovered the author of the outrage, and have Thomas Roch safely back in Healthful House. It is a consummation devoutly to be wished in the interest of the United States--I might even say of the whole world."

The two officers courteously saluted the Count, who responded with a nod. Captain Spade accompanied them to the gangway, and they were soon making for the cruiser, which had steamed near to pick them up.

Meanwhile the breeze had freshened considerably, and when, at a sign from d'Artigas, Captain Spade set sail again, the _Ebba_ skimmed swiftly through the inlet, and half an hour after was standing out to sea.

For an hour she continued steering east-northeast, and then, the wind, being merely a land breeze, dropped, and the schooner lay becalmed, her sails limp, and her flag drooping like a wet rag. It seemed that it would be impossible for the vessel to continue her voyage that night unless a breeze sprang up, and of this there was no sign.

Since the schooner had cleared the inlet Captain Spade had stood in the bows gazing into the water, now to port, now to starboard, as if on the lookout for something. Presently he shouted in a stentorian voice:

"Furl sail!"

The sailors rushed to their posts, and in an instant the sails came rattling down and were furled.

Was it Count d'Artigas' intention to wait there till daybreak brought a breeze with it? Presumably, or the sails would have remained hoisted to catch the faintest puff.

A boat was lowered and Captain Spade jumped into it, accompanied by a sailor, who paddled it towards an object that was floating on the water a few yards away.

This object was a small buoy, similar to that which had floated on the bosom of the Neuse when the _Ebba_ lay off Healthful House.

The buoy, with a towline affixed to it, was lifted into the boat that was then paddled to the bow of the _Ella_, from the deck of which another hawser was cast to the captain, who made it fast to the towline of the buoy. Having dropped the latter overboard again, the captain and the sailor returned to the ship and the boat was hoisted in.

Almost immediately the hawser tautened, and the _Elba_, though not a st.i.tch of canvas had been set, sped off in an easterly direction at a speed that could not have been less than ten knots an hour.

Night was falling fast, and soon the rapidly receding lights along the American coast were lost in the mist on the horizon.

CHAPTER V.

WHERE AM I?

(Notes by Simon Hart, the Engineer.)

Where am I? What has happened since the sudden aggression of which I was the victim near the pavilion.

I had just quitted the doctor, and was about to mount the steps, close the door and resume my post beside Thomas Roch when several men sprang upon me and knocked me down. Who are they? My eyes having been bandaged I was unable to recognize them. I could not cry for help, having been gagged. I could make no resistance, for they had bound me hand and foot. Thus powerless, I felt myself lifted and carried about one hundred paces, then hoisted, then lowered, then laid down.

Where? Where?

And Thomas Roch, what has become of him? It must have been he rather than I they were after. I was but Gaydon, the warder. None suspected that I was Simon Hart, the engineer, nor could they have suspected my nationality. Why, therefore, should they have desired to kidnap a mere hospital attendant?

There can consequently be no doubt that the French inventor has been carried off; and if he was s.n.a.t.c.hed from Healthful House it must have been in the hope of forcing his secret from him.

But I am reasoning on the supposition that Thomas Roch was carried off with me. Is it so? Yes--it must be--it is. I can entertain no doubt whatever about it. I have not fallen into the hands of malefactors whose only intention is robbery. They would not have acted in this way. After rendering it impossible for me to cry out, after having thrown me into a clump of bushes in the corner of the garden, after having kidnapped Thomas Roch they would not have shut me up--where I now am.

Where? This is the question which I have been asking myself for hours without being able to answer it.

However, one thing is certain, and that is that I have embarked upon an extraordinary adventure, that will end?--In what manner I know not--I dare not even imagine what the upshot of it will be. Anyhow, it is my intention to commit to memory, minute by minute, the least circ.u.mstance, and then, if it be possible, to jot down my daily impressions. Who knows what the future has in store for me? And who knows but what, in my new position, I may finally discover the secret of Roth's fulgurator? If I am to be delivered one day, this secret must be made known, as well as who is the author, or who are the authors, of this criminal outrage, which may be attended with such serious consequences.

I continually revert to this question, hoping that some incident will occur to enlighten me:

Where am I?

Let me begin from the beginning.

After having been carried by the head and feet from Healthful House, I felt that I was laid, without any brutality, I must admit, upon the stretchers of a row-boat of small dimensions.

The rocking caused by the weight of my body was succeeded shortly afterwards by a further rocking--which I attribute to the embarking of a second person. Can there be room for doubt that it was Thomas Roch? As far as he was concerned they would not have had to take the precaution of gagging him, or of bandaging his eyes, or of binding him. He must still have been in a state of prostration which precluded the possibility of his making any resistance, or even of being conscious of what was being done. The proof that I am not deceiving myself is that I could smell the unmistakable odor of ether. Now, yesterday, before taking leave of us, the doctor administered a few drops of ether to the invalid and--I remember distinctly--a little of this extremely volatile substance fell upon his clothing while he was struggling in his fit. There is therefore nothing astonishing in the fact that this odor should have clung to him, nor that I should have distinguished it, even beneath the bandages that covered my face.

Yes, Thomas Roch was extended near me in the boat. And to think that had I not returned to the pavilion when I did, had I delayed a few minutes longer, I should have found him gone!

Let me think. What could have inspired that Count d'Artigas with the unfortunate curiosity to visit Healthful House? If he had not been allowed to see my patient nothing of the kind would have happened.

Talking to Thomas Roch about his inventions brought on a fit of exceptional violence. The director is primarily to blame for not heeding my warning. Had he listened to me the doctor would not have been called upon to attend him, the door of the pavilion would have been locked, and the attempt of the band would have been frustrated.

As to the interest there could have been in carrying off Thomas Roch, either on behalf of a private person or of one of the states of the Old World, it is so evident that there is no need to dwell upon it.

However, I can be perfectly easy about the result. No one can possibly succeed in learning what for fifteen months I have been unable to ascertain. In the condition of intellectual collapse into which my fellow-countryman has fallen, all attempts to force his secret from him will be futile. Moreover, he is bound to go from bad to worse until he is hopelessly insane, even as regards those points upon which he has. .h.i.therto preserved his reason intact.

After all, however, it is less about Thomas Roch than myself that I must think just now, and this is what I have experienced, to resume the thread of my adventure where I dropped it:

After more rocking caused by our captors jumping into it, the boat is rowed off. The distance must be very short, for a minute after we b.u.mped against something. I surmise that this something must be the hull of a ship, and that we have run alongside. There is some scurrying and excitement. Indistinctly through my bandages I can hear orders being given and a confused murmur of voices that lasts for about five minutes, but I cannot distinguish a word that is said.

The only thought that occurs to me now is that they will hoist me on board and lower me to the bottom of the hold and keep me there till the vessel is far out at sea. Obviously they will not allow either Thomas Roch or his keeper to appear on deck as long as she remains in Pamlico Sound.

My conjecture is correct. Still gagged and bound I am at last lifted by the legs and shoulders. My impression, however, is that I am not being raised over a ship's bulwark, but on the contrary am being lowered. Are they going to drop me overboard to drown like a rat, so as to get rid of a dangerous witness? This thought flashes into my brain, and a quiver of anguish pa.s.ses through my body from head to foot. Instinctively I draw a long breath, and my lungs are filled with the precious air they will speedily lack.

No, there is no immediate cause for alarm. I am laid with comparative gentleness upon a hard floor, which gives me the sensation of metallic coldness. I am lying at full length. To my extreme surprise, I find that the ropes with which I was bound have been untied and loosened.

The tramping about around me has ceased. The next instant I hear a door closed with a bang.
