Ferson went swiftly on to explain his idea. This was none other than to construct two small projectors that would each automatically and ceaselessly generate artificial evolution vibrations, vibrations affecting a limited range as the sun's vibrations had affected all earth. These projectors in their compact cases could be worn on our bodies by each of us without being noticeable, and would keep each of us always thus in the range of the vital vibrations, so that we would not be affected by the world-wide absence of that which was causing this world atavism. Whatever great dampening wave Grant was sending out toward the sun to neutralize its evolution vibrations would not, of course, affect the vibrations of our own little projectors. The next two days saw us at work upon these projectors. The method of producing the evolution vibrations we knew, for as I have mentioned, they had been artificially produced in a small way by physicists upon Grant's first announcement of his theory. The second day, therefore, saw our projectors complete, small flat black cases that were strapped to our belts without being noticeable, each holding the tiny but marvelously powerful batteries that were the current-source, and the compact little generator that automatically and unendingly released the vital evolution vibrations for a range of several feet. With these completed and working, and secured thus by them from being ourselves affected by the terrible atavism that was upon the races of man, we began our greater work of locating Grant and the apparatus by which he was shutting off the sun's vibrations and loosing this horror on the earth. For horror it had now become, and the world was waking up to its true nature as every sort of brutal passion was released in terrible crime over it, and as the inexplicable mindlessness of men brought on terrific accidents. Already a dozen of the greatest governments in coöperation had called a conference of earth's greatest scientists at New York to explain or to halt at least the horror that was sweeping earth. To that conference they came with each a different and more incredible explanation of the thing, and to it went Ferson and I to give them the true explanation and to turn them toward the search for Grant that might yet save humanity. But that explanation was never given, for Ferson's first mention of world atavism was greeted with incredulous cries, and when he went on to mention Grant, such a derisive storm arose, that he was forced bodily from the meeting, leaving the scientists disputing fiercely over the most impossible of theories, supporting and opposing those theories by blows.
