“We must go to my estate immediately and retrieve the time-machine, which I left in the aerodrome,” said Kronous to me. “You can then return to your own age—it is not fair to ask you to stay longer in a world that is nearing ultimate ruin and chaos. We, the last remnants of mankind, will fight it out as best we can; but the war is not yours.”
I protested that I had no desire to leave him; that I would remain to the end; and also that I had implicit faith in the power of humanity to overcome its ultra-mundane foes.
Kronous smiled, a little sadly. “Nevertheless,” he persisted, “we must recover the time-machine. Thus your means of escape will be assured, no matter what happens. Will you go with me? I intend to make the trip this very forenoon.”
Of course, I could not object to this; and I was eager to accompany him. Apart from any use which I myself might make of it, the time-machine was too rare and valuable a thing to be left at the mercy of Venusian vandals, who might well destroy it in their campaign of nation-wide sabotage.
Kronous, Altus and myself made the brief trip in the same light air-vessel that had been used for the journey to Djarma. The fertile, luxuriant country-side with fronded woods and tall, airy spires of embowered mansions above which we had flown less than a week before, was now patched and blotched with devastation. Many of the houses had been gutted by fire; and the ravages of the vegetable mould from Venus had blighted many fields and forests, whose grass and foliage rotted beneath it to a nauseous grey slime.
Approaching the estate of Kronous, we saw that we should arrive none too soon. The Venusians had fired the house, and even their own quarters, and columns of smoke were arising from the doomed edifices. A dozen slaves were nearing the aerodrome with the obvious intention of trying to set it on fire, or of destroying or damaging the vessels which it contained.
The features of Kronous were deadly pale with anger. He said nothing as he steered the atomic monoplane directly toward the slaves, who had now seen us and were running headlong in a futile effort to escape. Several of them had been carrying lighted torches, which they now dropped. We swooped upon them, flying only a few feet above the ground in the open space that surrounded the aerodrome. Two of the slaves were caught and mangled by the sharp prow of the flier; and Altus and myself, using heat-ray projectors, accounted for five more as we passed them. Only three remained; and wheeling the vessel around in a sharp curve, and steering with one hand, Kronous himself dispatched them with his heat-ray.
We landed near the entrance of the aerodrome. Kronous went in; and a minute later, the time-vessel flew gently forth and settled on the platform. Kronous opened the door and called to me.
“You and I, Hugh, will return to Djarma in the time-ship; and Altus will take charge of the monoplane.”
No more of the Venusians were in sight; though we saw enough of their handiwork as we circled above the plantation before starting for Djarma. Kronous sighed at the ruin that had been wrought; but otherwise he gave no evidence of emotion, and maintained a stoical silence.
Half an hour later we were back in our apartments at Djarma; and the time-machine was securely housed in an aerodrome nearby. Since it had all the appearance of a small interplanetary flier, no one but ourselves ever dreamt of its real nature and use.
Every hour brought fresh news of the national damage inflicted by the planetary aliens and their plagues. The Martians had now declared open hostility. Their first movement had been to destroy all the human embassies and trading-stations on Mars and to seize a vast amount of ether-shipping; but before these overt actions were generally known, they had also assumed the offensive everywhere on earth. They possessed a frightful weapon, the zero-ray, which could penetrate animal tissue in an instant with fatal frost-bite. This weapon had been kept a secret; its invention and mode of operation were obscure to human scientists; and it was no less lethal and effective than the heat-ray. A battle was now going on in the Martian quarter of Djarma; and the Martians were holding their own. Air-vessels had tried dropping explosives on the quarter; but this was found to be more dangerous to humanity than to the Martians; for the latter were using some sort of unknown ray which detonated the explosives in mid-air, or even while they were still on board the air-vessels.
Chapter VI
The Departure
I was forced to marvel at the equanimity shown by the people of Akameria in the face of all these dire problems and dangers. Everywhere, scientists were coolly endeavoring to combat the new pests and were seeking to devise more efficacious weapons for use against the outsiders. No fear or alarm was exhibited by anyone. Probably the secret of this calm, imperturbable attitude lay in the lofty mental evolution and philosophic detachment that had been universally attained by the human race.
Knowing how insecure and impermanent was their tenure of existence among the inimical forces of the cosmos, men were prepared to meet their doom with resignation and dignity. Also, the race had grown old; and many, perhaps, were tired of the quotidian sameness of life and were ready to welcome anything, no matter how hazardous, in the nature of change.
Djarma was now full of refugees from the outlying plantations; and more were arriving hourly. But, gazing on the calm, unhurried throng, no one could have guessed the parlousness of the general situation. There was no evidence of strife or peril or apprehension; and even the war in the Martian quarter was conducted silently, since the weapons employed were all noiseless. Some of the Martian buildings, however, had been fired by heat-rays; and a pall of black smoke was rising and mushrooming above the ruddy flames.
Djarma had suffered less, so far, than most of the other Akamerian centers. The whole country was in disorder, and all communication was becoming seriously deranged. However, a few hours after the return of Kronous, Altus, and myself, there came from southern Akameria the warning of a new and more lethal plague than any which had hitherto appeared. A tiny Venusian micro-organism, a sort of aerial algae, which spread and increased with phenomenal celerity, had been turned loose and was rendering the air unbreathable for human beings over a vast and ever-growing area. It was harmless to the Venusians themselves, for the thick, vaporous air of their native jungles was full of it; and though it was deleterious to the Martians, the latter had prepared themselves beforehand and were all equipped with respiratory masks and atmospheric filters. But men were dying of slow asphyxiation, marked by the most painful pneumonic symptoms, wherever overtaken by the strange pest. It was visible in the air, which displayed a saffron color when invaded by the organism. For this reason, it soon became known as the Yellow Death.
Beyond the manufacture and distribution of air-masks on a large scale, nothing could be done by savants to combat the new plague. The saffron cloud was rolling northward hour by hour—a noiseless and irresistible doom; and the situation was indeed desperate. A conclave of scientists was called; and it was soon decided that humanity must evacuate the regions menaced by the deadly aerial scourge. The only resource was for men to retreat toward the Arctic circle and entrench themselves in dominions where the organism could not penetrate, since it thrived only in warm, tropical air.
“This,” said Kronous to me, sorrowfully, “is a preparatory step toward our final abandonment of the earth. The planetary aliens have conquered, as I knew they would. The cycle of human domination has completed itself; and the future belongs to the Venusians and Martians. I venture to predict, however, that the Martians will soon enslave the Venusians and rule them with a far stricter hand than we humans.”
