"All the better. It would suit us best to get back while it is dark, and even beach the "Albatross" if we can. Those fellows will fancy we are a long way off to the northward, and never think of keeping a look-out. If we have to stop a day or two on the island--"

"We'll stop, and if we have to fight an army of natives?"

"We'll fight," said Robur. "We'll fight then for our "Albatross.""

The engineer went forward to the men, who were waiting for orders.

"My lads," he said to them, "we cannot knock off yet. We must work till day comes."

They were all ready to do so. The stern-screw had now to be treated as the other had been. The damage was the same, a twisting from the violence of the hurricane during the pa.s.sage across the southern pole.

But to get the screw on board it seemed best to stop the progress of the aeronef for a few minutes, and even to drive her backwards. The engines were reversed. The aeronef began to fall astern, when Tom Turner was surprised by a peculiar odor.

This was from the gas given off by the match, which had acc.u.mulated in the box, and was now escaping from the cabin. "Hallo!" said the mate, with a sniff.

"What is the matter?" asked Robur.

"Don't you smell something? Isn't it burning powder?"

"So it is, Tom."

"And it comes from that cabin."

"Yes, the very cabin--"

"Have those scoundrels set it on fire?"

"Suppose it is something else!" exclaimed Robur. "Force the door, Tom; drive in the door!"

But the mate had not made one step towards it when a fearful explosion shook the "Albatross." The cabins flew into splinters. The lamps went out. The electric current suddenly failed. The darkness was complete. Most of the suspensory screws were twisted or broken, but a few in the bow still revolved.

At the same instant the hull of the aeronef opened just behind the first deck-house, where the engines for the fore-screw were placed; and the after-part of the deck collapsed in s.p.a.ce.

Immediately the last suspensory screw stopped spinning, and the "Albatross" dropped into the abyss.

It was a fall of ten thousand feet for the eight men who were clinging to the wreck; and the fall was even faster than it might have been, for the fore propeller was vertical in the air and still working!

It was then that Robur, with extraordinary coolness, climbed up to the broken deck-house, and seizing the lever reversed the rotation, so that the propeller became a suspender. The fall continued, but it was checked, and the wreck did not fall with the accelerating swiftness of bodies influenced solely by gravitation; and if it was death to the survivors of the "Albatross" from their being hurled into the sea, it was not death by asphyxia amid air which the rapidity of descent rendered unbreathable.

Eighty seconds after the explosion, all that remained of the "Albatross" plunged into the waves!

Chapter XXI

THE INSt.i.tUTE AGAIN

Some weeks before, on the 13th of June, on the morning after the sitting during which the Weldon Inst.i.tute had been given over to such stormy discussions, the excitement of all cla.s.ses of the Philadelphia population, black or white, had been much easier to imagine than to describe.

From a very early hour conversation was entirely occupied with the unexpected and scandalous incident of the night before. A stranger calling himself an engineer, and answering to the name of Robur, a person of unknown origin, of anonymous nationality, had unexpectedly presented himself in the club-room, insulted the balloonists, made fun of the aeronauts, boasted of the marvels of machines heavier than air, and raised a frightful tumult by the remarks with which he greeted the menaces of his adversaries. After leaving the desk, amid a volley of revolver shots, he had disappeared, and in spite of every endeavor, no trace could be found of him.

a.s.suredly here was enough to exercise every tongue and excite every imagination. But by how much was this excitement increased when in the evening of the 13th of June it was found that neither the president nor secretary of the Weldon Inst.i.tute had returned to their homes! Was it by chance only that they were absent? No, or at least there was nothing to lead people to think so. It had even been agreed that in the morning they would be back at the club, one as president, the other as secretary, to take their places during a discussion on the events of the preceding evening.

And not only was there the complete disappearance of these two considerable personages in the state of Pennsylvania, but there was no news of the valet Frycollin. He was as undiscoverable as his master. Never had a Negro since Toussaint L'Ouverture, Soulouque, or Dessaline had so much talked about him.

The next day there was no news. Neither the colleagues nor Frycollin had been found. The anxiety became serious. Agitation commenced. A numerous crowd besieged the post and telegraph offices in case any news should be received. There was no news.

And they had been seen coming out of the Weldon Inst.i.tute loudly talking together, and with Frycollin in attendance, go down Walnut Street towards Fairmount Park! Jem Chip, the vegetarian, had even shaken hands with the president and left him with "Tomorrow!"

And William T. Forbes, the manufacturer of sugar from rags, had received a cordial shake from Phil Evans who had said to him twice, "Au revoir! Au revoir!"

Miss Doll and Miss Mat Forbes, so attached to Uncle Prudent by the bonds of purest friendship, could not get over the disappearance, and in order to obtain news of the absent, talked even more than they were accustomed to.

Three, four, five, six days pa.s.sed. Then a week, then two weeks, and there was nothing to give a clue to the missing three. The most minute search had been made in every quarter. Nothing! In the park, even under the trees and brushwood. Nothing! Always nothing! Although here it was noticed that the gra.s.s looked to be pressed down in a way that seemed suspicious and certainly was inexplicable; and at the edge of the clearing there were traces of a recent struggle. Perhaps a band of scoundrels had attacked the colleagues here in the deserted park in the middle of the night!

It was possible. The police proceeded with their inquiries in all due form and with all lawful slowness. They dragged the Schuyllkill river, and cut into the thick bushes that fringe its banks; and if this was useless it was not quite a waste, for the Schuyllkill is in great want of a good weeding, and it got it on this occasion.

Practical people are the authorities of Philadelphia!

Then the newspapers were tried. Advertis.e.m.e.nts and notices and articles were sent to all the journals in the Union without distinction of color. The "Daily Negro," the special organ of the black race, published a portrait of Frycollin after his latest photograph. Rewards were offered to whoever would give news of the three absentees, and even to those who would find some clue to put the police on the track. "Five thousand dollars! Five thousand dollars to any citizen who would--"

Nothing was done. The five thousand dollars remained with the treasurer of the Weldon Inst.i.tute.

Undiscoverable! Undiscoverable! Undiscoverable! Uncle Prudent and Phil Evans, of Philadelphia!

It need hardly be said that the club was put to serious inconvenience by this disappearance of its president and secretary. And at first the a.s.sembly voted urgency to a measure which suspended the work on the "Go-Ahead." How, in the absence of the princ.i.p.al promoters of the affair, of those who had devoted to the enterprise a certain part of their fortune in time and money--how could they finish the work when these were not present? It were better, then, to wait.

And just then came the first news of the strange phenomenon which had exercised people's minds some weeks before. The mysterious object had been again seen at different times in the higher regions of the atmosphere. But n.o.body dreamt of establishing a connection between this singular reappearance and the no less singular disappearance of the members of the Weldon Inst.i.tute. In fact, it would have required a very strong dose of imagination to connect one of these facts with the other.

Whatever it might be, asteroid or aerolite or aerial monster, it had reappeared in such a way that its dimensions and shape could be much better appreciated, first in Canada, over the country between Ottawa and Quebec, on the very morning after the disappearance of the colleagues, and later over the plains of the Far West, where it had tried its speed against an express train on the Union Pacific.

At the end of this day the doubts of the learned world were at an end. The body was not a product of nature, it was a flying machine, the practical application of the theory of "heavier than air." And if the inventor of the aeronef had wished to keep himself unknown he could evidently have done better than to try it over the Far West. As to the mechanical force he required, or the engines by which it was communicated, nothing was known, but there could be no doubt the aeronef was gifted with an extraordinary faculty of locomotion. In fact, a few days afterwards it was reported from the Celestial Empire, then from the southern part of India, then from the Russian steppes.

Who was then this bold mechanician that possessed such powers of locomotion, for whom States had no frontiers and oceans no limits, who disposed of the terrestrial atmosphere as if it were his domain?

Could it be this Robur whose theories had been so brutally thrown in the face of the Weldon Inst.i.tute the day he led the attack against the utopia of guidable balloons? Perhaps such a notion occurred to some of the wide-awake people, but none dreamt that the said Robur had anything to do with the disappearance of the president and secretary of the Inst.i.tute.

Things remained in this state of mystery when a telegram arrived from France through the New York cable at 11-37 A.M. on July 13. And what was this telegram? It was the text of the doc.u.ment found at Paris in a snuff-box revealing what had happened to the two personages for whom the Union was in mourning.

So, then, the perpetrator of this kidnapping "was" Robur the engineer, come expressly to Philadelphia to destroy in its egg the theory of the balloonists. He it was who commanded the "Albatross!"

He it was who carried off by way of reprisal Uncle Prudent, Phil Evans and Frycollin; and they might be considered lost for ever. At least until some means were found of constructing an engine capable of contending with this powerful machine their terrestrial friends would never bring them back to earth.

What excitement! What stupor! The telegram from Paris had been addressed to the members of the Weldon Inst.i.tute. The members of the club were immediately informed of it. Ten minutes later all Philadelphia received the news through its telephones, and in less than an hour all America heard of it through the innumerable electric wires of the new continent.

No one would believe it! "It is an unseasonable joke," said some. "It is all smoke," said others. How could such a thing be done in Philadelphia, and so secretly, too? How could the "Albatross" have been beached in Fairmount Park without its appearance having been signaled all over Pennsylvania?

Very good. These were the arguments. The incredulous had the right of doubting. But the right did not last long. Seven days after the receipt of the telegram the French mail-boat "Normandie" came into the Hudson, bringing the famous snuff-box. The railway took it in all haste from New York to Philadelphia.

It was indeed the snuff-box of the President of the Weldon Inst.i.tute.

Jem Chip would have done on at day to take some more substantial nourishment, for he fell into a swoon when he recognized it. How many a time had he taken from it the pinch of friendship! And Miss Doll and Miss Mat also recognized it, and so did William T. Forbes, Truck Milnor, Bat T. Fynn, and many other members. And not only was it the president's snuff-box, it was the president's writing!
