Whole Mountain Ranges of Glowing Lava Were Hurled up Miles High.
Then waves of molten matter rose up again out of the gulfs, tens of miles high and hundreds of miles long, surged forward, and met with a concussion like that of millions of earthly thunder-clouds. Minute after minute they remained writhing and struggling with each other, flinging up spurts of flaming matter far above their crests. Other waves followed them, climbing up their bases as a sea-surge runs up the side of a smooth, slanting rock. Then from the midst of them a jet of living fire leapt up hundreds of miles into the lurid atmosphere above, and then, with a crash and a roar which shook the vast Jovian firmament, the battling lava-waves would split apart and sink down into the all-surrounding fire-ocean, like two grappling giants who had strangled each other in their final struggle.
"It's just Hell let loose!" said Murgatroyd to himself as he looked down upon the terrific scene through one of the port-holes of the engine-room; "and, with all respect to my lord and her ladyship, those that come this near almost deserve to stop in it."
Meanwhile, Redgrave and Zaidie and their three guests were so absorbed in the tremendous spectacle, that for a few moments no one noticed that they were dropping faster and faster towards the world which Murgatroyd, according to his lights, had not inaptly described. As for Zaidie, all her fears were for the time being lost in wonder, until she saw her husband take a swift glance round upwards and downwards, and then go up into the conning-tower. She followed him quickly, and said:
"What is the matter, Lenox, are we falling too quickly?"
"Much faster than we should," he replied, sending a signal to Murgatroyd to increase the force by three-tenths.
The answering signal came back, but still the Astronef continued to fall with terrific rapidity, and the awful landscape beneath them—a landscape of fire and chaos—broadened out and became more and more distinct.
He sent two more signals down in quick succession. Three-fourths of the whole repulsive power of the engines was now being exerted—a force which would have been sufficient to hurl the Astronef up from the surface of the Earth like a feather in a whirlwind. Her downward course became a little slower, but still she did not stop. Zaidie, white to the lips, looked down upon the hideous scene beneath and slipped her hand through Redgrave's arm. He looked at her for an instant and then turned his head away with a jerk, and sent down the last signal.
The whole energy of the engines was now directing the maximum of the R. Force against the surface of Jupiter, but still, as every moment passed in a speechless agony of apprehension, it grew nearer and nearer. The fire-waves mounted higher and higher, the roar of the fiery surges grew louder and louder. Then in a momentary lull, he put his arm round her, drew her close up to him and kissed her and said:
"That's all we can do, dear. We've come too close and he's too strong for us."
She returned his kiss and said quite steadily:
"Well, at any rate, I'm with you, and it won't last long, will it?"
"Not very long now, I'm afraid," he said between his clenched teeth. And then he pulled her close to him again, and together they looked down into the storm-tossed hell towards which they were falling at the rate of nearly a hundred miles a minute.
Almost the next moment they felt a little jerk beneath their feet—a jerk upwards; and Redgrave shook himself out of the half stupor into which he was falling and said:
"Hullo, what's that? I believe we're stopping—yes, we are—and we're beginning to rise, too. Look, dear, the clouds are coming down upon us—fast too! I wonder what sort of miracle that is. Ay, what's the matter, little woman?"
Zaidie's head had dropped heavily on his shoulder. A glance showed him that she had fainted. He could do nothing more in the conning-tower, so he picked her up and carried her towards the companion-way, past his three guests, who were standing in the middle of the upper deck round a table on which lay a large sheet of paper.
He took her below and laid her on her bed, and in a few minutes he had brought her to and told her that it was all right. Then he gave her a drink of brandy-and-water and went back to the upper deck. As he reached the top of the stairway one of the astronomers came towards him with a sheet of paper in his hand, smiling gravely, and pointing to a sketch upon it.
He took the paper under one of the electric lights and looked at it. The sketch was a plan of the Jovian System. There were some signs written along one side, which he did not understand, but he divined that they were calculations. Still, there was no mistaking the diagram. There was a circle representing the huge bulk of Jupiter; there were four smaller circles at varying distances in a nearly straight line from it, and between the nearest of these and the planet was the figure of the Astronef, with an arrow pointing upwards.
"Ah, I see!" he said, forgetting for a moment that the other did not understand him, "that was the miracle! The four satellites came into line with us just as the pull of Jupiter was getting too much for our engines, and their combined pull just turned the scale. Well, thank God for that, sir, for in a few minutes more we should have been cinders!"
The astronomer smiled again as he took the paper back. Meanwhile the Astronef was rushing upward like a meteor through the clouds. In ten minutes the limits of the Jovian atmosphere were passed. Stars and suns and planets blazed out of the black vault of Space, and the great disc of the World that Is to Be once more covered the floor of Space beneath them—an ocean of cloud, covering continents of lava and seas of flame, the scene of the natal throes of a world which some day will be.
They passed Io and Europa, which changed from new to full moons as they sped by towards the Sun, and then the golden yellow crescent of Ganymede also began to fill out to the half and full disc, and by the tenth hour of Earth-time, after they had risen from its surface, the Astronef was once more lying beside the gate of the Crystal City.
At midnight on the second night after their return, the ringed shape of Saturn, attended by his eight satellites, hung in the zenith magnificently inviting. The Astronef's engines had been replenished after the exhaustion of their struggle with the might of Jupiter. They said farewell to their friends of the dying world. The doors of the air-chamber closed. The signal tinkled in the engine-room, and a few moments later a blurr of white lights on the brown background of the surrounding desert was all they could see of the Crystal City under whose domes they had seen and learnt so much.
