Soon the Afghan mountaineers could hear the explosion of its leaf-buds amid their passes, echoing like distant thunder; and, at the same time, it rushed like a Juggernaut upon Central India. Spreading in all directions, and growing with the speed of express-trains, the tendrils of the mighty vine proceeded to enmesh the Asian realms. Overshadowing vales, peaks, hills, plateaus, deserts, cities and sea-boards with its titan leaves, it invaded Europe and Africa; and then, bridging the Bering Straits, it entered North America and ran southward, ramifying on all sides till the whole continent, and also South America even to Tierra de Fuego, had been buried beneath the masses of insuperable foliage.
Frantic efforts to stay the progress of the plant were made by armies with bombs and cannon, with lethal sprays and gases; but all in vain. Everywhere humanity was smothered beneath the vast leaves, like those of some omnipresent upas, which emitted a stupefying and narcotic odor that conferred upon all who inhaled it a swift euthanasia.
Soon the plant had netted the whole globe; for the seas offered little or no barrier to its full-grown stems and tendrils. When the process of growth was complete, the anti-Martian moiety of the human race had joined the uncouth monsters of pre-historic time in that limbo of oblivion to which all superseded and out-dated genera have gone. But, through the divine clemency of the plant-lord, the final death that overtook the “die-hards” was no less easy than irresistible.
Stilton and a few of his associates contrived to evade the general doom for awhile by fleeing in a rocket-ship to the Antarctic plateau. Here, as they were congratulating themselves on their escape, they saw far-off on the horizon the rearing of the swift stems, beneath whose foliage the ice and snow appeared to melt away in rushing torrents. These torrents soon became a diluvial sea, in which the last dogmatists were drowned. Only in this way did they elude the euthanasia of the great leaves, which had overtaken all their fellows.
THE VAULTS OF YOH-VOMBIS
Preface
As an interne in the terrestrial hospital at Ignarh, I had charge of the singular case of Rodney Severn, the one surviving member of the Octave Expedition to Yoh-Vombis, and took down the following story from his dictation. Severn had been brought to the hospital by the Martian guides of the Expedition. He was suffering from a horribly lacerated and inflamed condition of the scalp and brow, and was wildly delirious part of the time and had to be held down in his bed during recurrent seizures of a mania whose violence was doubly inexplicable in view of his extreme debility.
The lacerations, as will be learned from the story, were mainly self-inflicted. They were mingled with numerous small round wounds, easily distinguished from the knife-slashes, and arranged in regular circles, through which an unknown poison had been injected into Severn’s scalp. The causation of these wounds was difficult to explain; unless one were to believe that Severn’s story was true, and was no mere figment of his illness. Speaking for myself, in the light of what afterwards occurred, I feel that I have no other recourse than to believe it. There are strange things on the red planet; and I can only second the wish that was expressed by the doomed archaeologist in regard to future explorations.
The night after he finished telling me his story, while another doctor than myself was supposedly on duty, Severn managed to escape from the hospital, doubtless in one of the strange seizures at which I have hinted: a most astonishing thing, for he had seemed weaker than ever after the long strain of his terrible narrative, and his demise had been hourly expected. More astonishing still, his bare footsteps were found in the desert, going toward Yoh-Vombis, till they vanished in the path of a light sandstorm; but no trace of Severn himself has yet been discovered.
The Narrative of Rodney Severn
If the doctors are correct in their prognostication, I have only a few Martian hours of life remaining to me. In those hours I shall endeavor to relate, as a warning to others who might follow in our footsteps, the singular and frightful happenings that terminated our researches among the ruins of Yoh-Vombis. Somehow, even in my extremity, I shall contrive to tell the story; since there is no one else to do it. But the telling will be toilsome and broken; and after I am done, the madness will recur, and several men will restrain me, lest I should leave the hospital and return across many desert leagues to those abominable vaults beneath the compulsion of the malignant and malevolent virus which is permeating my brain. Perhaps death will release me from that abhorrent control, which would urge me down to bottomless underworld warrens of terror for which the saner planets of the solar system can have no analogue. I say perhaps…for, remembering what I have seen, I am not sure that even death will end my bondage….
There were eight of us, professional archaeologists with more or less terrene and interplanetary experience, who set forth with native guides from Ignarh, the commercial metropolis of Mars, to inspect that ancient, aeon-deserted city. Allan Octave, our official leader, held his primacy by virtue of knowing more about Martian archaeology than any other Terrestrial on the planet; and others of the party, such as William Harper and Jonas Halgren, had been associated with him in many of his previous researches. I, Rodney Severn, was more of a newcomer, having spent but a few months on Mars; and the greater part of my own ultra-terrene delvings had been confined to Venus.
I had often heard of Yoh-Vombis, in a vague and legendary sort of manner, and never at first hand. Even the ubiquitous Octave had never seen it. Builded by an extinct people whose history has been lost in the latter, decadent eras of the planet, it remains a dim and fascinating riddle whose solution has never been approached…and which, I trust, may endure forevermore unsolved by man. Certainly I hope that no one will ever follow in our steps….
Contrary to the impression we had received from Martian stories, we found that the semi-fabulous ruins lay at no great distance from Ignarh with its terrestrial colony and consulates. The nude, spongy-chested natives had spoken deterringly of vast deserts filled with ever-swirling sand-storms, through which we must pass to reach Yoh-Vombis; and in spite of our munificent offers of payment, it had been difficult to secure guides for the journey. We had provisioned ourselves amply and had prepared for all emergencies that might eventuate during a long trip. Therefore, we were pleased as well as surprised when we came to the ruins after seven hours of plodding across the flat, treeless, orange-yellow desolation to the south-west of Ignarh. On account of the lesser gravity, the journey was far less tiring than one who is unfamiliar with Martian conditions might expect. But because of the thin, Himalaya-like air, and the possible strain on our hearts, we had been careful not to hasten.
Our coming to Yoh-Vombis was sudden and spectacular. Climbing the low slope of a league-long elevation of bare and deeply eroded stone, we saw before us the shattered walls of our destination, whose highest tower was notching the small, remote sun that glared in stifled crimson through the floating haze of fine sand. For a little, we thought that the domeless, three-angled towers and broken-down monoliths were those of some unlegended city, other than the one we sought. But the disposition of the ruins, which lay in a sort of arc for almost the entire extent of the low and gneissic elevation, together with the type of architecture, soon convinced us that we had found our goal. No other ancient city on Mars had been laid out in that manner; and the strange, many-terraced buttresses of the thick walls, like the stairways of forgotten Anakim, were peculiar to the prehistoric race that had built Yoh-Vombis. Moreover, Yoh-Vombis was the one remaining example of this architecture, aside from a few fragments in the neighborhood of Ignarh, which we had previously examined.
