The other two, the representatives of the army and of the navy, though probably as much astonished as the baronet, said nothing. They knew considerably more than the latter about the capabilities of science; and though they might possibly entertain grave doubts as to the success of the professor's experiment, they did not feel called upon to express an off-hand opinion that it would prove a failure. The baronet might well be excused his hasty expression of incredulity. Towering above and in front of him, filling up the entire space of the enormous shed from end to end and from ground to roof-timbers, he saw an immense cylinder, pointed at both ends, and constructed entirely of the polished silver-like metal which the professor had called aethereum. The sides of the ship from stem to stern formed a series of faultless curves; the conical bow or fore body of the ship being somewhat longer, and therefore sharper, than the after body, which partook more of the form of an ellipse than of a cone; the curvilinear hull was supported steadily in position by two deep broad bilge-keels, one on either side and about one-third the extreme length of the ship; and, attached to the stern of the vessel by an ingeniously devised ball-and-socket joint in such a manner as to render a rudder unnecessary, was to be seen a huge propeller having four tremendously broad sickle-shaped blades, the palms of which were hollowed in such a manner as to gather in and concentrate the air, or water, about the boss and powerfully project it thence in a direct line with the longitudinal axis of the ship. Crowning the whole there was a low superstructure immediately over and of the same length as the bilge-keels, very much resembling the upper works of a double- bowed vessel such as are some of the small Thames river steamers. This was decked over, and afforded a promenade about two hundred feet long by thirty feet wide. And, lastly, rising from the centre of this deck there was a spacious pilot-house with a dome-like roof, from the interior of which the movements of the vessel could be completely controlled. The entire hull of the vessel, excepting the double-bowed superstructure, was left unpainted, and it shone like a polished mirror. The superstructure, however, was painted a delicate grey tint, with the relief of a massive richly gilded cable moulding all round the shear- strake and the further adornment of a broad ribbon of a rich crimson hue rippling through graceful wreaths of gilded scroll-work at bow and stern, the name _Flying Fish_ being inscribed on the ribbon in gold letters. Altogether, notwithstanding her unusual form, the aerial ship was an exceedingly graceful and elegant object, and, but for her enormous proportions, looked admirably adapted for her work.
