“It looks,” said Lapham, “as if someone or something had blown up all the atoms in this part of the Sahara, and had then started a totally new process of re-integration and evolution, with the development of soil, water, minerals, atmosphere and plants such as could never have existed on the earth during any of its geological epochs.”
This startling theory was discussed pro and con, and was finally adopted as the only explanation that contained elements of possibility. But it remained to determine the agency of the geological and evolutionary changes; and of course no one could propound anything decisive as to the nature of the agency. The whole thing was enough to stagger the imagination of a Jules Verne; and with scientists of such indubitable rectitude as Lapham and his fellows, the fantasies of lawless imagination had no place. They were concerned only with things that could be verified and proven according to natural laws.
Several days were devoted to analyzing, re-analyzing and theorizing. Then a report of the conditions that had been found was drawn up, and it was decided to send a summary of this report by radio to Europe and America. An attempt to use the radios carried by the party revealed a peculiar condition of absolute static that prevailed above the vapor-covered region. No messages could be sent or received across this region, though communication was readily established with points that were not in a direct line with the new area, such as Rome, Cairo, Petrograd, Havana and New Orleans. This condition of static was permanent—at least, many repeated efforts, at all hours of the day and night, were utterly ineffectual. One of the planes, carrying a radio-apparatus, soared to a height of nine thousand feet above the encampment, and sought to establish the desired connection, but in vain. It was necessary for the plane to cross the whole cloud-mass, to the northern side, before New York and London could receive and return its messages.
“It would seem,” observed Lapham, “as if some sort of ultra-powerful cosmic ray, that prevents the passage of radio vibrations, had been turned on this part of the Sahara. Evidently there is a screen of interfering force.”
While arguments as to the validity of this theory, the nature and origin of the conjectural rays, and their possible relation to the geologic changes, were still in progress, two members of the party complained of feeling ill. Both of them, on examination by Dr. Adams, were discovered to be afflicted with cutaneous symptoms resembling those that had been developed by many of the caravan from Timbuctoo. The characteristic patches of bright green,
with purplish borders, were spreading rapidly on their arms and shoulders, and soon invaded the exposed portions of the skin. The two men became mildly delirious within a few hours, and gave evidence of extreme nervous depression. Simultaneously with this turn of their illness, Dr. Adams himself grew conscious of a sudden feeling of indisposition. Obviously, the insulative clothing worn by the explorers had been inadequate for their protection against whatever lethal forces were inherent in the new soil, minerals and vapor-laden atmosphere. It was decided that the party must return to civilization immediately, before others should be stricken.
Camp was broken up, and the two planes were headed for Great Britain. During the brief journey, all of the scientists began to fall ill, and the pilot of one of the planes collapsed, allowing the controlless air-vessel to plunge into the Atlantic near the coast of Spain. The crew of the second plane, seeing the accident, flew gallantly to the rescue, and succeeded in saving Lapham and Dr. Adams, who were struggling in the waters. Their companions, including the sick pilot, were all drowned. It was a sad remnant of the expedition which landed at the London airport several hours later.

In the meanwhile, the summary of the explorers’ report, dispatched with so much difficulty by radio, had been published in all the leading dailies of the world and had aroused universal interest amid the scientific fraternity. The press was full of theories and conjectures, some of them extremely wild and fantastic. One journal went so far as to insinuate that the Saharan manifestations were part of a plan for world-dominion that was being put into practice by the United Oriental Federation, which then included China, Indo-China, Burma, and Japan; and others were inclined to name Germany as the instigator.
On the very same day when Lapham and his companions reached London, there came from the United States the news of a terrible and mysterious cataclysm, which had occurred in Missouri and which had involved at least half of this state. Though the time was still mid-winter and the ground was covered with unmelting snow, a tremendous storm of dust had appeared, in which many towns and cities, including St. Louis, had been utterly swallowed up. All communications with these towns and cities had been cut off, and no message, no living thing nor evidence of life, had come forth from the storm. There were great billowing clouds, that soared to a stupendous height, and from which emerged a sound like the rumbling of thunder, or the explosion of unaccountable tons of dynamite. The dust, of unbelievable fineness, settled upon many miles of the adjacent areas, and nothing could be done or determined for days, since all who dared to approach the raging storm were instantly lost and never returned. The terror and mystery of a
cataclysm so unparalleled, so far beyond all explanation or imagination, fell like a black pall upon the United States, and horrified the whole civilized world. The dust from the storm, which was analyzed at once, was found to consist of partially disintegrated molecules; and it required no great reach of fantasy for scientists, reporters and the general public to associate the upheaval with the Saharan sand-storm that had given birth to a terrain of unearthly strangeness.
The news was brought to Lapham and his fellows in the hospital to which they had been taken from the plane. Several of the party were already too ill to comprehend intelligently what had taken place; but Lapham and Dr. Adams, both of whom were less severely stricken than the others, were at once prepared to comment on the report from America.
“I believe,” said Lapham, “that some cosmic process has been instituted which may threaten the integrity and even the continued existence of our world—at least, of any world which we could call ours, and in which human beings could dwell and survive. I predict that within a few weeks, geological and atmospheric conditions similar to those which we found in the Sahara will also prevail in Missouri.”
This prophetic utterance, made to reporters from the Times and the Daily Mail, received considerable publicity and added to the world-wide consternation and terror that was being felt.
While dispatches announcing the continuation of the atomic storm were still agitating five continents, several of the returned explorers died from the unknown malady by which they had been seized. Their cases were characterized by nearly all the symptoms that had been noted in the members of the unfortunate caravan from Timbuctoo, but lacked the pulmonary disorders, from which, it was evident, the use of oxygen-tanks had saved the expedition. Extreme weakness, melancholia, the green, leprous patches, locomotor ataxia, partial blindness and the final necrosis of the bones were all present, and little could be done to mitigate them by any of the attendant doctors, among whom were the most renowned specialists of Great Britain, France, and America. Lapham and Dr. Adams were the only members of the party who survived, and neither of them was ever wholly well at any future time. Till the end of their days, both men suffered from more or less mental depression and from recurrent outbreaks of the cutaneous symptoms. An odd aftermath of the whole affair was, that similar maladies were contracted in a milder degree by many scientists who examined the mineral and vegetable specimens that had been carefully brought back from Africa by the expedition. No one could isolate or identify the properties that gave rise to such disorders; but it was assumed that rays belonging to the ultra-violet or infra-red ranges, and more powerful than anything hitherto discovered, were being given off by the odd substances. These rays, it was all too evident, were deleterious to human health and life.
While Lapham and Dr. Adams were still lying in hospital, fresh news-items continued to come from America. One of
these items was, that two planes, driven by world-famous aviators, had tried to surmount the terrific dust-storm that still raged in Missouri. The storm, like its Saharan fellow, was about twelve thousand feet in height, and it was not thought that any difficulty would be encountered in crossing it at a sufficient altitude. Also, it was believed that some valuable data might be gathered thereby. The planes flew to an elevation of thirteen thousand before approaching the borders of the storm, but on passing above the rim of the involved area, they were both seen to disappear suddenly in mid-air by people who were watching their flight with field glasses. Neither of the planes ever returned to earth, nor could any sign of them be located.
“Fools!” cried Lapham, when he heard the news of their disappearance. “Of course, when they invaded the vertical area of the storm, they were exposed to the same disintegrative influences that are operating on the earth below. These influences, as I surmised, are coming from outer space. The planes and their aviators have been dissolved into sub-molecular dust.”
No more attempts were made to cross the storm, and a widespread exodus of people from the adjacent regions, which had been going on ever since the initial cataclysm, became almost universal in the next few days. Hardly anyone remained, with the exception of a few redoubtable scientists, who wished to be on the ground for purposes of investigation when the upheaval should subside.
Within a week, the storm began to lessen in height and fury, and the clouds became broken and less dense. But, as in the case of the African disturbance, there were minor agitations and upswirlings for another week or more. Then it was perceived that masses of vapor were replacing the dust; and a solid canopy of pearly-grey cloud was soon formed above the whole region. All around this region, the winter snows were buried beneath a mile-wide zone of the sub-molecular powder.
In spite of the awful fate that had befallen the Timbuctoo caravan and the geological expedition, there were several scientists brave enough to venture within the St. Louis area when the rising vapors gave proof that the processes of disintegration were at an end. They found the same exotic soil, the same minerals, metals and water that had been discovered in the heart of the Juf desert; but the alien plant-forms had not yet begun to appear. Some of the water was secured for analysis: apart from the usual constituents of water, it was found to contain an element oddly similar to a certain synthetic gas, more lethal than anything hitherto devised, which had lately been invented for use in warfare. This element, however, was not decomposable into the separate elements from which its analogue had been formed by American chemists. Still another gaseous component was isolated, but could not be identified or allied with anything familiar to chemistry. Scarcely had the analysis been
completed and its results given to the world, when the chemists who had undertaken the analysis, and also the investigators who had obtained the water, were all stricken down with an illness which differed in certain ways from the one that had been undergone by their Saharan predecessors. All the usual symptoms were presented; and coincidentally there was a falling-out of all the hair on the heads, faces, limbs and bodies of those affected, till not even the finest down remained. Then the places where the hair had been were covered rapidly with a grey formation resembling mould. The formation, on being analyzed, was proven to consist of minute vegetable organisms, which increased with remarkable fecundity and soon began to eat the skin and flesh beneath. No antiseptic could combat the ravages of the grey mould, and the victims died in atrocious agony within a few hours. It was surmised that the water must have given rise to these new symptoms, by some process of infection; but how the infection could have occurred was a mystery, since all manner of possible precautions had been taken in handling the water.
A little before the death of these hardy investigators, two singular astronomical discoveries were made. Lapham’s theory that rays of an ultra-powerful type were being turned upon the earth from some ulterior source, had led to an intensive study of the neighboring planets, particularly of Mars and Venus, through the new telescopes with four hundred-inch reflectors, with which observatories in Colorado and the Spanish Pyrenees had been equipped. It was thought that the rays might be emanating from one of the planets. Mars, by this time, was definitely known to be inhabited, but little had been yet learned about Venus, on account of the cloudy envelope with which that world is surrounded. Now, under the close continual scrutiny to which it was subjected, three flashes of white light, occurring at intervals of seventy minutes and lasting for about ninety seconds, were seen to pierce the cloudy envelope, in a region not far from the equator of Venus. The three flashes emanated from the same spot. A little later during the same night, Dr. Malkin of the Colorado observatory, though all his interest was still centered upon the orb of Venus, now almost at meridian, was forced to observe within his field of vision a tiny satellite or asteroid which was apparently following the revolution of the earth. Observations were made, leading to the sensational discovery that this new satellite was no more than a thousand miles distant, and was paralleling the movement of the earth in a position exactly above the state of Missouri! Calculations revealed that it was about two hundred feet in diameter.
Dr. Malkin’s two discoveries were announced to the world, and were followed the next day by a report from the Pyrenean observatory, telling of another tiny body that had been located far in the south, directly above the vapor-shrouded region in northern Africa. In size, movement and distance from the earth, this body was similar to the American satellite. The two announcements were the cause of much public excitement, and many con
jectures were made as to the origin and character of the two minute bodies, whose very positions made it natural for everyone to connect them at once with the geological phenomena in the subjacent areas. It remained, however, for Roger Lapham to predict that the three flashes on Venus, observed by Dr. Malkin on the same night as his discovery of the first body, would soon be followed by the appearance of three new satellites, and also by three more storms of dust in different parts of the world.
“I believe,” said Lapham, “that the satellites are mechanical spheres that have been discharged from Venus, and that they contain living beings and also apparatus for the creation and use of the destructive and re-compositive rays that have brought about the singular manifestations in Africa and America. The flashes that Dr. Malkin saw were doubtless caused by the discharge of new spheres. And if Venus had been under continual observation by the new telescopes, two earlier flashes would have been seen, one preceding the atomic storm in Africa and the other the storm in America. I am at a loss to understand, however, why the two spheres were not observed long ago, since it is probable that they have been within telescopic range ever since the onset of the atomic storms.”
IV
There was a great division of opinion among scientists, as well as among the general public, concerning the validity of Lapham’s theory on the origin of the satellites; but no one felt any doubt regarding their problematic relation to the dust-storms and the new terrains. It was perceived that the two orbs were different in color, the African orb inclining to a ruddy tint and the American to a bluish tone. But suddenly, under Dr. Malkin’s observation, two nights after the initial discovery, this latter orb took on the reddish hue of its African fellow. Lapham, on hearing of this, went so far as to venture a surmise that the changing colors of the sphere had some connection with the nature of the rays that were being emitted, and that probably the bluish color was associated with a ray promoting the integration of mineral forms, and the reddish with one that had relation to the development of vegetable life.
“What I think is,” he went on, “that the people of Venus are trying to establish in certain parts of our world the geological, botanical and meteorological conditions that prevail in their own. The establishment of such conditions is no doubt preliminary to an attempt at invasion. The Venusians, it is likely, could no more exist under the conditions that are favorable to us, than we could under thei
rs. Therefore, before coming to earth, they must create for themselves a suitable environment, in which their colonies can land. Certainly, the hot, steaming soil and vaporous atmosphere, found in the Sahara and in Missouri, are similar to those that characterize the planet Venus.”
Though some were still incredulous, or unable to realize imaginatively what
was taking place, a wave of terror inundated the world at the promulgation of this surmise. Hence-forward, the cool theorizing of Lapham and other scientists went on side by side with outbursts of frantic fear and of old-time religious hysteria on the part of the multitude. No one could know when and where the weird, extra-planetary menace would strike next, nor the possible scope of its operations; and the dread anticipation of this menace became a demoralizing and paralyzing force that affected more or less the field of nearly all human activities. The men of science, the astronomers, the chemists, the physicists, the inventors, the electricians, the medical brotherhood, were the only classes of society who, as a whole, went about their usual work with a quickening rather than a slackening of their faculties. Researches were rapidly begun in laboratories all over the world, to find medical agents that would be efficacious in fighting the new diseases caused by contact with the Venusian minerals, air, water, and vegetable forms; and in spite of the certain danger, many excursions were made into the vapor-hidden terrains to procure the needful substances for study in the various laboratories. The tale of resultant death and suffering was long and sad, and testified to the undauntable heroism of human scientists. Also, a number of inventors, who had long sought the secret of a process by which molecules and atoms could be broken up and re-integrated on a large scale, now redoubled their efforts in the hope of enabling humanity to combat the probable conversion of wide areas of the earth into foreign atomic patterns.
