Then they enter the new tunnel, followed by Captain Spade. If I could but follow them! If I could but breathe for awhile the bracing air of the Atlantic, of which the interior of Back Cup only receives attenuated puffs, so to speak.

From September 26 to October 10.—Fifteen days have elapsed. 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.
