We were posted on all the news of the world; and with my growing mastery of the language, I soon came to the point where I no longer required the interpretation of Kronous to understand the announcements. Much of this news was not reassuring, but served to confirm the prophetic fears that had been voiced by my host. There were daily outbreaks on the part of Venusian slaves all over the planet; and in many cases much damage was inflicted before they could be subdued. Also, these outbreaks were beginning to display a mysterious concertion and a degree of mentality of which the Venusians had not hitherto been believed capable. Acts of sabotage, as well as personal assaults, were increasingly common; and the sabotage in particular often showed a rational intelligence. Even at this early date, there were those who suspected that the Venusians were being aided and incited by the Martians; but there was no tangible proof of such abetting at the time.

One day, from Djarma, there came the news of that bizarre mineral plague known as the Black Rot. One by one the buildings in the suburbs of Djarma were being attacked by this novel disease, which caused their synthetic stone and metal to dissolve inch by inch in a fine black powder. The Rot was the work of a micro-organism which must somehow have been introduced from Venus, where its ravages had been noted in certain mountain-ranges. Its appearance on earth was a mystery, but had all the air of another act of sabotage. It was capable of devouring half the elements known to chemistry; and off-hand, nothing could be discovered to arrest its progress, though all the Akamerian chemists were at work on the problem.

Kronous and I watched in the televisor the working of the Black Rot. Somehow, it was inexpressibly terrifying to see the slowly spreading area of silent and utter devastation, the crumbled or half-eaten buildings from which the occupants had fled. The thing had started on the outskirts of Djarma, and was steadily devouring the city in an ever-broadening arc.

All the best-known scientists of Akameria were summoned in conclave at Djarma to study the Rot and devise if possible a means of retardation. Kronous, who was a renowned chemist and microscopist, was among those called upon. He offered to take me with him, and of course I accepted with the utmost eagerness.

The trip was a matter of no more than forty miles, and we made it in a light air-vessel belonging to Kronous—a sort of monoplane run by atomic power.

Though I had already familiarized myself with many of the scenes of Djarma by television, the city was a source of absorbing fascination to me. It was far smaller than New York and was widely spaced, with many gardens and exuberant semi-tropical parks meandering through its whole extent. The architecture was nearly all of the same open, aerial type that I had seen in Kronous’ home. The streets were broad and spacious and there were comparatively few large buildings. The whole effect was one of supreme grace and beauty.

The streets were not overcrowded with people, and no one ever seemed to be in a hurry. It was strange to see the grotesque Martians and bestial Venusians mingling everywhere with humans of the same type as Kronous. The stature and build of Kronous were about the average and it was rare to see a man who was taller than five feet six inches. I, of course, with my five feet eleven, was very conspicuous and attracted much attention.

The conclave of savants was being held in a large edifice, builded expressly for such meetings, at the heart of Djarma. Entering, we found that about two hundred men, some of whom were extremely old and venerable, had already gathered in the council-chamber. Much general discussion was going on; and those who had ideas to suggest were listened to in respectful silence. Kronous and I took seats amid the gathering. So intent were all these men on the problem to be solved, that few of them even vouchsafed me a curious glance.

Peering at the faces about me, I was awed by an impression of supreme intellectuality and wisdom—the garnered lore of incalculable ages. Also, on many of these countenances I perceived the marks of a world-old ennui, and the stamp of a vague sterility, an incipient decadence.

For some time, Kronous and I listened to the discussion that was in progress. Pondering the various data brought forward, I was struck by the fact that all the elements assailed by the Black Rot belonged at the opposite end of the scale from radium in regard to their atomic activity and explosiveness.

Sotto voce, I commented on this to Kronous. “Is it not possible,” I suggested, “that radium might be of some use in combatting the plague? I believe you have told me that radium, like any other element, is easily manufacturable nowadays.”

“That is a striking inspiration,” said Kronous thoughtfully. “And it might be worth trying. With our chemical mastery we can make all the radium we need at will in our laboratories. With your permission I am going to broach the idea.”

He arose and spoke briefly amid the attentive silence of the assembly. “Credit for the idea,” he announced as he ended, “must be given to Huno Paskon, a young colonial from Pallas, whom I have brought to earth as my guest.”

I felt myself abashed by the grave, unanimous gaze of these erudite and revered savants, who all eyed me in a manner that I could not fathom. Somehow, it seemed unthinkably presumptuous for me to have made any suggestion in their presence.

However, there appeared to be much serious debate going on—a widespread discussion in which the proposed use of radium was manifestly meeting with great favor. At last a venerable savant named Argo Kan, who was spokesman of the assembly, rose and said:

“I vote for an immediate trial of the method suggested by Kronous Alkon and Huno Paskon.”

Others, one by one, stood up and cast similar verbal votes, till the motion had been approved by nearly everyone present.

The meeting then dispersed, and I learned from Kronous that work was being immediately begun in local laboratories for the preparation of radium on a large scale and its utilization in the most effective form.

In less than an hour, several chemists were ready to visit the area of destruction with portable machines in which radium was disintegrated and used as a fine spray. It was magical in arresting the Black Rot, which had been eating its way continuously into the city, creeping from house to house along the crumbling pavements. The whole affected area, which now covered several square miles, was soon surrounded by a cordon of men equipped with the radium-machines; and, to the vast relief of the people of Djarma and Akameria, the plague was pronounced under control.

Chapter IV

Captured by Cannibals

During our stay in Djarma, Kronous and I were guests in a fine building set apart for the use of visiting scientists. I was amazed at the sybaritic luxury developed by this people—a luxury which, though illimitably and unimaginably resourceful, was at no time in excess of the bounds of good taste. There were baths that would have been the envy of a Roman emperor, and beds that would have reduced Cleopatra to beggary. We were lulled by rich, aerial music from no visible source, and were served with food and with all other necessities as if by intangible hands, at the mere verbal expression of a wish. Of course, there was a mechanical secret to such wonders; but the secret was cleverly hidden, and the means never obtruded itself. Humbly I realized how far ahead of ourselves were these men of 15,000 A.D., with their quiet and consummate mastery of natural laws—a mastery which none of them seemed to regard as being of any great value or importance.

I was somewhat embarrassed by the honor paid to myself as the originator of a means of retarding the Black Rot, and could only feel that my inspiration had been merely a fortunate accident. Compliments, both written and verbal, were showered upon me by scientific dignitaries; and it was only through the intercession of Kronous, who explained my aversion to publicity, that I was able to avoid numerous invitations.
