“Now order that man to lift the ship on to his shoulders.”

M’Bongwele duly repeated the order, without the slightest expectation that it would be fulfilled; and the man—who would have plunged into a blazing bonfire if he had been so ordered—advanced, and, to the unutterable astonishment of himself, the king, and in fact the whole concourse of natives, raised the gigantic structure to his shoulders and held it there with scarcely an effort.

“Now, tell him to toss us into the air,” commanded von Schalckenberg, shouting down from the gangway to Lualamba.

And in another second the terrified king and his suite felt a slight movement, and saw the earth sinking far away beneath them. This was altogether too much for the suite, who grovelled on the deck in mortal fear; and even king M’Bongwele felt his courage rapidly oozing away as he sat uneasily in his deck-chair convulsively gripping its arms and glancing anxiously about him.

The ascent was continued to a height of about fifteen thousand feet, at which altitude the wretched savages were shivering even more with cold than they had hitherto done with fear. The ship was then headed straight for the sea, which she soon reached, and, speeding onward at the rate of thirty miles an hour, her course was continued, accompanied by a gradual descent until the land was lost sight of; when a wide sweep was made, and, at a height of only one hundred feet above the waves, the return journey was commenced. This experience proved sufficient, and more than sufficient, for M’Bongwele; he was completely cowed; and when he found himself hovering over the illimitable sea, without a sign of land in any direction, he flung himself upon his knees before the professor and piteously entreated to be restored to his home and people, abjectly promising that he and they would be the willing slaves of the White Spirits for ever; and as for the ruins, the Spirits might do whatever they chose with them, freely and without let or hindrance. This was all very well, but von Schalckenberg had not yet fully carried out his programme; he had still one more item in the entertainment which he was determined to produce, and which he fully believed would render M’Bongwele’s subjugation not only complete but permanent.

Accordingly, on returning to their starting-place (by which time it was nearly dark), the demoralised warriors, who had all but given up their king as lost, were set to work by von Schalckenberg’s orders to collect wood for a gigantic bonfire. This was soon done, and the fire was kindled; but, much of the wood being green, an immense cloud of smoke was raised, with very little flame, which exactly suited the professor’s purpose. When the fire was fairly alight, the troops were re-formed in line as close to the ship as possible, and M’Bongwele and his suite were arranged in position on the deck immediately beneath the pilot-house walls. By this time it was perfectly dark, save for the starlight and the flickering gleam of the bonfire; and the air was stark calm.

Gradually and imperceptibly the dense cloud of smoke which hung motionless over the smouldering pile became faintly luminous. The radiance grew stronger and stronger, and presently an immense circular disc of light appeared reflected on the slowly-rising cloud of vapour, in which a host of forms were indistinctly traceable. Another moment and a loud ejaculation of astonishment burst from the savage spectators, for, with another sudden brightening of the luminous disc there appeared the phantom presentment of M’Bongwele’s troops drawn up as they had appeared a couple of hours before, when the king had first boarded the Flying Fish So clear and vivid was the representation that it met with instant recognition, amid loud murmurs of amazement from the beholders; the king being quite as strongly moved as any of his subjects.

“Do you recognise the vision?” demanded the professor sternly of M’Bongwele.

“I do, I do. Those are the spirits of my bravest soldiers,” murmured the king. “Truly the Spirits of the Winds have wondrous powers.”

“You say well,” answered von Schalckenberg. “Now, look again and you shall see a few of our warriors.”
