Brande heeded them not.

"This night," said he, with culminating enthusiasm, "the cloud-capped towers, the gorgeous palaces, the solemn temples, shall dissolve. To this great globe itself--this paltry speck of less account in s.p.a.ce than a dew-drop in an ocean--and all its sorrow and pain, its trials and temptations, all the pathos and bathos of our tragic human farce, the end is near. The way has been hard, and the journey overlong, and the burden often beyond man's strength. But that long-drawn sorrow now shall cease. The tears will be wiped away. The burden will fall from weary shoulders. For the fulness of time has come. This earth shall die! And death is peace.

"I stand," he cried out in a strident voice, raising his arm aloft, "I may say, with one foot on sea and one on land, for I hold the elemental secret of them both. And I swear by the living G.o.d--Science incarnate--that the suffering of the centuries is over, that for this earth and all that it contains, from this night and for ever, _Time will be no more!_"

A great cry rose from the people. "Give us another day--only another day!"

But Brande made answer: "It is now too late."

"Too late!" the people wailed.

"Yes, too late. I warned you long ago. Are you not yet ready? In two hours the disintegrating agent will enter on its work. No human power could stop it now. Not if every particle of the material I have compounded were separated and scattered to the winds. Before I set my foot upon this rock I applied the key which will release its inherent energy. I myself am powerless."

"Powerless," sobbed the auditors.

"Powerless! And if I had ten thousand times the power which I have called forth from the universal element, I would use it towards the issue I have forecast."

Thereupon he turned away. Doom sounded in his words. The hand of Death laid clammy fingers on us. Edith Metford's strength failed at last. It had been sorely tested. She sank into my arms.

"Courage, true heart, our time has come," I whispered. "We start for the steamer at once. The horses are ready." My arrangements had been already made. My plan had been as carefully matured as any ever made by Brande himself.

"How many horses?"

"Three. One for you; another for Natalie; the third for myself. The rest must accept the fate they have selected."

The girl shuddered as she said, "But your interference with the formula?

You are sure it will destroy the effect?"

"I am certain that the particular result on which Brande calculates will not take place. But short of that, he has still enough explosive matter stored to cause an earthquake. We are not safe within a radius of fifty miles. It will be a race against time."

"Natalie will not come."

"Not voluntarily. You must think of some plan. Your brain is quick. We have not a moment to lose. Ah, there she is! Speak to her."

Natalie was crossing the open ground which led from the glen to Brande's laboratory. She did not observe us till Edith called to her. Then she approached hastily and embraced her friend with visible emotion. Even to me she offered her cheek without reserve.

"Natalie," I said quickly, "there are three horses saddled and waiting in the palm grove. The _Esmeralda_ is still lying in the harbour where we landed. You will come with us. Indeed, you have no choice. You must come if I have to carry you to your horse and tie you to the saddle. You will not force me to put that indignity upon you. To the horses, then!

Come!"

For answer she called her brother loudly by his name. Brande immediately appeared at the door of his laboratory, and when he perceived from whom the call had come he joined us.

"Herbert," said Natalie, "our friend is deserting us. He must still cling to the thought that your purpose may fail, and he expects to escape on horseback from the fate of the earth. Reason with him yet a little further."

"There is no time to reason," I interrupted. "The horses are ready. This girl (pointing as I spoke to Edith Metford) takes one, I another, and you the third--whether your brother agrees or not."

"Surely you have not lost your reason? Have you forgotten the drop of water in the English Channel?" Brande said quietly.

"Brande," I answered, "the sooner you induce your sister to come with me the better; and the sooner you induce these maniac friends of yours to clear out the better, for your enterprise will fail."

"It is as certain as the law of gravitation. With my own hand I mixed the ingredients according to the formula."

"And," said I, "with my own hand I altered your formula."

Had Brande's heart stopped beating, his face could not have become more distorted and livid. He moved close to me, and, glaring into my eyes, hissed out:

"You altered my formula?"

"I did," I answered recklessly. "I multiplied your figures by ten where they struck me as insufficient."

"When?"

I strode closer still to him and looked him straight in the eyes while I spoke.

"That night in the Red Sea, when Edith Metford, by accident, mixed morphia in your medicine. The night I injected a subtle poison, which I picked up in India once, into your blood while you slept, thereby baffling some of the functions of your extraordinary brain. The night when in your sleep you stirred once, and had you stirred twice, I would have killed you, then and there, as ruthlessly as you would kill mankind now. The night I did kill your lieutenant, Rockingham, and throw his body overboard to the sharks."

Brande did not speak for a moment. Then he said in a gentle, uncomplaining voice:

"So it now devolves on Grey. The end will be the same. The Labrador expedition will succeed where I have failed." To Natalie: "You had better go. There will only be an explosion. The island will probably disappear. That will be all."

"Do you remain?" she asked.

"Yes. I perish with my failure."

"Then I perish with you. And you, Marcel, save yourself--you coward!"

I started as if struck in the face. Then I said to Edith: "Be careful to keep to the track. Take the bay horse. I saddled him for myself, but you can ride him safely. Lose no time, and ride hard for the coast."

"Arthur Marcel," she answered, so softly that the others did not hear, "your work in the world is not yet over. There is the Labrador expedition. Just now, when my strength failed, you whispered 'courage.'

Be true to yourself! Half an hour is gone."

At length some glimmer of human feeling awoke in Brande. He said in a low, abstracted voice: "My life fittingly ends now. To keep you, Natalie, would only be a vulgar murder." The old will power seemed to come back to him. He looked into the girl's eyes, and said slowly and sternly: "Go! I command it."

Without another word he turned away from us. When he had disappeared into the laboratory, Natalie sighed, and said dreamily:

"I am ready. Let us go."

CHAPTER XVIII.

THE FLIGHT.

I led the girls hurriedly to the horses. When they were mounted on the ponies, I gave the bridle-reins of the bay horse--whose size and strength were necessary for my extra weight--to Edith Metford, and asked her to wait for me until I announced Brande's probable failure to the people, and advised a _sauve qui peut_.

Hard upon my warning there followed a strange metamorphosis in the crowd, who, after the pa.s.sing weakness at the lecture, had fallen back into stoical indifference, or it may have been despair. The possibility of escape galvanized them into the desire for life. Cries of distress, and prayers for help, filled the air. Men and women rushed about like frightened sheep without concert or any sensible effort to escape, wasting in futile scrambles the short time remaining to them. For another half hour had now pa.s.sed, and in sixty minutes the earthquake would take place.

"Follow us!" I shouted, as with my companions I rode slowly through the camp. "Keep the track to the sea. I shall have the steamer's boats ready for all who may reach the sh.o.r.e alive."
