I do not know how the fact will help me in any way, even if the entrance to the tunnel is partly uncovered, but I cannot afford to miss any detail that may possibly aid in my escape from Back Cup.
_August 29_.--This morning I am witnessing the departure of the tug. The Count d'Artigas is, no doubt, going off in the _Ebba_ to fetch the sections of Thomas Roch's engines. Before embarking, the Count converses long and earnestly with Engineer Serko, who, apparently, is not going to accompany him on this trip, and is evidently giving him some recommendations, of which I may be the object. Then, having stepped on to the platform, he goes below, the lid shuts with a bang, and the tug sinks out of sight, leaving a trail of bubbles behind it.
The hours go by, night is coming on, yet the tug does not return. I conclude that it has gone to tow the schooner, and perhaps to destroy any merchant vessels that may come in their way.
It cannot, however, be absent very long, as the trip to America and back will not take more than a week.
Besides, if I can judge from the calm atmosphere in the interior of the cavern, the _Ebba_ must be favored with beautiful weather. This is, in fact, the fine season in this part of the world. Ah! if only I could break out of my prison!
_From August 29 to September 10_.--Thirteen days have gone by and the _Ebba_ has not returned. Did she then not make straight for the American coast? Has she been delayed by a buccaneering cruise in the neighborhood of Back Cup? It seems to me that Ker Karraje's only desire would be to get back with the sections of Roch's engines as soon as possible. Maybe the Virginian foundry had not quite finished them.
Engineer Serko does not display the least anxiety or impatience. He continues to greet me with his accustomed ironical cordiality, and with a kindly air that I distrust--with good reason. He affects to be solicitous as to my health, urges me to make the best of a bad job, calls me Ali Baba, assures me that there is not, in the whole world, such an enchanting spot as this Arabian Nights cavern, observes that I am fed, warmed, lodged, and clothed, that I have no taxes to pay, and that even the inhabitants of the favored principality of Monaco do not enjoy an existence more free from care.
