Before the day was out! But in two hours the Albatross would be annihilated! The dynamite cartridge was like a torpedo fastened to her hull, and would accomplish her destruction in midair. The breeze freshened, and the aeronef was carried to the northeast. Although her speed was but moderate, she would be out of sight of the Chatham Islands before sunrise. To return against the wind she must have her propellers going, particularly the one in the bow.
“Tom,” said the engineer, “turn the lights full on.”
“Yes, sir.”
“And all hands to work.”
“Yes, sir.”
There was no longer any idea of putting off the work till tomorrow. There was now no thought of fatigue. Not one of the men of the Albatross failed to share in the feelings of his chief. Not one but was ready to do anything to recapture the fugitives!
As soon as the screw was in place they would return to the island and drop another anchor, and give chase to the fugitives. Then only would they begin repairing the stern-screw; and then the aeronef could resume her voyage across the Pacific to X Island.
It was important, above all things, that the Albatross should not be carried too far to the northeast, but unfortunately the breeze grew stronger, and she could not head against it, or even remain stationary. Deprived of her propellers she was an unguidable balloon. The fugitives on the shore knew that she would have disappeared before the explosion blew her to pieces.
Robur felt much disappointment at seeing his plans so interfered with. Would it not take him much longer than he thought to get back to his old anchorage?
While the work at the screw was actively pushed on, he resolved to descend to the surface of the sea, in the hope that the wind would there be lighter. Perhaps the Albatross would be able to remain in the neighborhood until she was again fit to work to windward.
The maneuver was instantly executed. If a passing ship had sighted the aerial machine as she sunk through the air, with her electric lights in full blaze, with what terror would she have been seized!
When the Albatross was a few hundred feet from the waves she stopped. Unfortunately Robur found that the breeze was stronger here than above, and the aeronef drifted off more rapidly. He risked being blown a long way off to the northeast, and that would delay his return to Pitt Island. In short, after several experiments, he found it better to keep his ship well up in the air, and the Albatross went aloft to about ten thousand feet. There, if she did not remain stationary, the drifting was very slight. The engineer could thus hope that by sunrise at such an altitude he would still be in sight of the island.
Robur did not trouble himself about the reception the fugitives might have received from the natives—if there were any natives. That they might help them mattered little to him. With the powers of offense possessed by the Albatross they would be promptly terrified and dispersed. The capture of the prisoners was certain, and once he had them again, “They will not escape from X Island!”
About one o’clock in the morning the fore-screw was finished, and all that had to be done was to get it back to its place. This would take about an hour. That done, the Albatross would be headed southwest and the stern-screw could be taken in hand.
And how about the match that was burning in the deserted cabin?—the match of which more than a third was now consumed? And the spark that was creeping along to the dynamite?
Assuredly if the men of the aeronef had not been so busy one of them would have heard the feeble sputtering that was going on in the deckhouse. Perhaps he would have smelt the burning powder! He would doubtless have become uneasy! And told Tom Turner! And then they would have looked about, and found the box and the infernal machine; and then there would have been time to save this wonderful Albatross and all she bore!
But the men were at work in the bow, twenty yards away from the cabin. Nothing brought them to that part of the deck; nothing called off their attention from their work. Robur was there working with his hands, excellent mechanic as he was. He hurried on the work, but nothing was neglected, everything was carefully done. Was it not necessary that he should again become absolute master of his invention? If he did not recapture the fugitives they would get away home. They would begin inquiring into matters. They might even discover X Island, and there would be an end to this life, which the men of the Albatross had created for themselves, a life that seemed superhuman and sublime.
And here Tom Turner came up to the engineer. It was a quarter past one. “It seems to me, sir, that the breeze is falling, and going round to the west.”
“What does the barometer say?” asked Robur, after looking up at the sky.
“It is almost stationary, and the clouds seem gathering below us.”
“So they are, and it may be raining down at the sea; but if we keep above the rain it makes no difference to us. It will not interfere with the work.”
“If it is raining it is not a heavy rain,” said Tom. “The clouds do not look like it, and probably the wind has dropped altogether.”
“Perhaps so, but I think we had better not go down yet. Let us get into going order as soon as we can, and then we can do as we like.”
At a few minutes after two the first part of the work was finished. The fore-screw was in its place, and the power was turned on. The speed was gradually increased, and the Albatross, heading to the southwest, returned at
