Under the directions of Engineer Serko and Thomas Roch the sections of the engines have been fitted together. Then the construction of their supports is begun. These supports are simple trestles, fitted with transverse troughs or grooves of various degrees of inclination, and which could be easily installed on the deck of the _Ebba_, or even on the platform of the tug, which can be kept on a level with the surface.
Thus Ker Karraje, will be ruler of the seas, with his yacht. No warship, however big, however powerful, will be able to cross the zone of danger, whereas the _Ebba_ will be out of range of its guns. If only my notice were found! If only the existence of this lair of Back Cup were known! Means would soon be found, if not of destroying the place, at least of starving the band into submission!
_October 20_.--To my extreme surprise I find this morning that the tug has gone away again. I recall that yesterday the elements of the piles were renewed, but I thought it was only to keep them in order. In view of the fact that the outside can now be reached through the new tunnel, and that Thomas Roch has everything he requires, I can only conclude that the tug has gone off on another marauding expedition.
Yet this is the season of the equinoctial gales, and the Bermudan waters are swept by frequent tempests. This is evident from the violent gusts that drive back the smoke through the crater and the heavy rain that accompanies it, as well as by the water in the lagoon, which swells and washes over the brown rocks on its shores.
But it is by no means sure that the _Ebba_ has quitted her cove. However staunch she may be, she is, it seems to me, of too light a build to face such tempests as now rage, even with the help of the tug.
On the other hand, although the tug has nothing to fear from the heavy seas, as it would be in calm water a few yards below the surface, it is hardly likely that it has gone on a trip unless to accompany the schooner.
I do not know to what its departure can be attributed, but its absence is likely to be prolonged, for it has not yet returned.
Engineer Serko has remained behind, but Ker Karraje, Captain Spade, and the crew of the schooner, I find, have left.
Life in the cavern goes on with its usual dispiriting monotony. I pass hour after hour in my cell, meditating, hoping, despairing, following in fancy the voyage of my little barrel, tossed about at the mercy of the currents and whose chances of being picked up, I fear, are becoming fainter each day, and killing time by writing my diary, which will probably not survive me.
Thomas Roch is constantly occupied in his laboratory manufacturing his deflagrator. I still entertain the conviction that nothing will ever induce him to give up the secret of the liquid's composition; but I am perfectly aware that he will not hesitate to place his invention at Ker Karraje's service.
I often meet Engineer Serko when my strolls take me in the direction of the Beehive. He always shows himself disposed to chat with me, though, it is true, he does so in a tone of impertinent frivolity. We converse upon all sorts of subjects, but rarely of my position. Recrimination thereanent is useless and only subjects me to renewed bantering.
_October 22_.--To-day I asked Engineer Serko whether the _Ebba_ had put to sea again with the tug.
"Yes, Mr. Simon Hart," he replied, "and though the clouds gather and loud the tempest roars, be in no uneasiness in regard to our dear _Ebba_."
"Will she be gone long?"
"We expect her back within forty-eight hours. It is the last voyage Count d'Artigas proposes to make before the winter gales render navigation in these parts impracticable."
"Is her voyage one of business or pleasure?"
"Of business, Mr. Hart, of business," answered Engineer Serko with a smile. "Our engines are now completed, and when the fine weather returns we shall resume offensive operations."
"Against unfortunate merchantmen."
"As unfortunate as they are richly laden."
"Acts of piracy, whose impunity will, I trust, not always be assured," I cried..
