And now everything was done, or nearly done; but much more than the "palazzo" had been undertaken and completed, for the lady of many millions had commanded an air-ship to be built for her own personal use and private pleasure with an aerodrome for its safe keeping and anchorage. This airship was the crux of the whole business, for the men employed to build it were confident that it would never fly, and laughed with one another as they worked to carry out a woman's idea and a woman's design. How could it fly without an engine?--they very sensibly demanded,--for engine there was none! However, they were paid punctually and most royally for their labours; and when, despite their ominous predictions, the ship was released on her trial trip, manipulated by Giulio Rivardi, who ascended in her alone, sailing the ship with an ease and celerity hitherto unprecedented, they were more scared than enthusiastic.
Surely some devil was in it!--for how could the thing fly without any apparent force to propel it? How was it that its enormous wings spread out on either side as by self-volition and moved rhythmically like the wings of a bird in full flight? Every man who had worked at the design was more or less mystified. They had, according to plan and instructions received, "plumed" the airship for electricity in a new and curious manner, but there was no battery to generate a current. Two small boxes or chambers, made of some mysterious metal which would not "fuse" under the strongest heat, were fixed, one at either end of the ship;--these had been manufactured secretly in another country and sent to Sicily by Morgana herself,--but so far, they contained nothing.
They seemed unimportant--they were hardly as large as an ordinary petrol-can holding a gallon. When Rivardi had made a trial ascent he had inserted in each of these boxes a cylindrical tube made to fit an interior socket as a candle fits into a candle-stick,--all the workmen watched him, waiting for a revelation, but he made none. He was only particular and precise as to the firm closing down of the boxes when the tubes were in. And then in a few minutes the whole machine began to palpitate noiselessly like a living thing with a beating heart,--and to the amazement and almost fear of all who witnessed what seemed to be a miracle, the ship sprang up like a bird springing from the ground, and soared free and away into space, its vast white wings cleaving the air with a steady rise and fall of rhythmic power. Once aloft she sailed in level flight, apparently at perfect ease--and after several rapid "runs," and circlings, descended slowly and gracefully, landing her pilot without shock or jar. He was at once surrounded and was asked a thousand questions which it was evident he could not answer.
