Maybe I shall be able to find out from what I hear and see ere I make my escape, if escape be possible.

The _Ebba_ continues on her way in the same mysterious manner. I am free to walk about the deck, without, however, being able to go beyond the fore hatchway. Once I attempted to go as far as the bows where I could, by leaning over, perceive the schooner's stem as it cut through the water, but acting, it was plain, on orders received, the watch on deck turned me back, and one of them, addressing me brusquely in harsh, grating English, said:

"Go back! Go back! You are interfering with the working of the ship!"

With the working of the ship! There was no working.

Did they realize that I was trying to discover by what means the schooner was propelled? Very likely, and Captain Spade, who had looked on, must have known it, too. Even a hospital attendant could not fail to be astonished at the fact that a vessel without either screw or sails was going along at such a speed. However this may be, for some reason or other, the bows of the _Ebba_ are barred to me.

Toward ten o'clock a breeze springs up--a northwest wind and very favorable--and Captain Spade gives an order to the boatswain. The latter immediately pipes all hands on deck, and the mainsail, the foresail, staysail and jibs are hoisted. The work could not have been executed with greater regularity and discipline on board a man-of-war.

The _Ebba_ now has a slight list to port, and her speed is notably increased. But the motor continues to push her along, as is evident from the fact that the sails are not always as full as they ought to be if the schooner were bowling along solely under their action. However, they continue to render yeoman's service, for the breeze has set in steadily.

The sky is clear, for the clouds in the west disappear as soon as they attain the horizon, and the sunlight dances on the water.

My preoccupation now is to find out as near as possible where we are bound for. I am a good-enough sailor to be able to estimate the approximate speed of a ship. In my opinion the _Ebba_ has been travelling at the rate of from ten to eleven knots an hour. As to the direction we have been going in, it is always the same, and I have been able to verify this by casual glances at the binnacle. If the fore part of the vessel is barred to Warder Gaydon he has been allowed a free run of the remainder of it. Time and again I have glanced at the compass, and noticed that the needle invariably pointed to the east, or to be exact, east-southeast.

These are the conditions in which we are navigating this part of the Atlantic Ocean, which is bounded on the west by the coast of the United States of America.

I appeal to my memory. What are the islands or groups of islands to be found in the direction we are going, ere the continent of the Old World is reached?

North Carolina, which the schooner quitted forty-eight hours ago, is traversed by the thirty-fifth parallel of latitude, and this parallel, extending eastward, must, if I mistake not, cut the African coast at Morocco. But along the line, about three thousand miles from America, are the Azores. Is it presumable that the _Ebba_ is heading for this archipelago, that the port to which she belongs is somewhere in these islands which constitute one of Portugal's insular domains? I cannot admit such an hypothesis.

Besides, before the Azores, on the line of the thirty-fifth parallel, is the Bermuda group, which belongs to England. It seems to me to be a good deal less hypothetical that, if the Count d'Artigas was entrusted with the abduction of Thomas Roch by a European Power at all, it was by the United Kingdom of Great Britain and Ireland. The possibility, however, remains that he may be acting solely in his own interest.

Three or four times during the day Count d'Artigas has come aft and remained for some time scanning the surrounding horizon attentively. When a sail or the smoke from a steamer heaves in sight he examines the passing vessel for a considerable time with a powerful telescope. I may add that he has not once condescended to notice my presence on deck.
