Mildmay having, during the progress of this conversation, received a hint from the professor how to act, had quietly, and as if not particularly interested in what was going forward, sauntered off to the pilot-house, where, stationing himself at the engine and other levers controlling the movements of the ship, he awaited further instructions. The professor, having promised to give the savages a specimen of their visitors' power, now waved his right hand very slowly and impressively skyward, as a signal to the watchful Mildmay, loudly exclaiming as he did so: "Lualamba will now accompany the four Spirits of the Winds to yonder cloud," pointing, as he spoke, to a single small white fleecy cloud which was floating at the moment across the sun's disc. Dexterously manipulating the various valves, Mildmay caused the _Flying Fish_ to rise with a gentle and almost imperceptible motion from the earth. So gentle was the movement that Lualamba was utterly unconscious of it, and it was not until some seconds had elapsed that he fully realised what was happening. The savages below, however, no sooner heard von Schalckenberg's exclamation than, to their inexpressible horror, they beheld the huge structure, round which they were standing, lift itself off the earth without the slightest visible effort and begin to rise into the air. Many of them were so overpowered by astonishment that they could only stand, open-mouthed and as motionless as statues, staring at the extraordinary sight; others, however, remembering the stringent orders of the king, and feeling that the prize which they had believed to be so secure was not only escaping them but also carrying off one of their number, rushed forward, and, whilst some fruitlessly attempted to grasp and hold the smooth and polished hull, others seized and clung tenaciously to the rope-ladder. The weight of some seven or eight natives clinging to the dangling ladder had, of course, no visible effect upon the movement of the great ship; and, finding themselves being helplessly dragged skyward, they let go their hold with a yell of dismay when they were some four or five yards from the earth, upon which they dropped back heavily.
