The Invisible Ray

He had been fingering a switch as he spoke. Now he turned it on triumphantly. A curious snapping and crackling noise followed, becoming more rapid, and as it mounted in intensity I could smell a pungent odour of ozone which told of an electric discharge. On went the machine until we could feel heat radiating from it. Then came a piercing burst of greenish-blue light from a long tube which looked like a curious mercury vapour lamp.
After a few minutes of this Prescott took a small crucible of black lead. “Now we are ready to try it,” he cried in great excitement. “Here I have a crucible containing some copper. Any substance in the group would do, even hydrogen if there was any way I could handle the gas. I place it in the machine – so. Now if you could watch inside you would see it change; it is now rubidium, now silver, now caesium. Now it is a hitherto unknown element which I have named after myself, presium, now a second unknown element, cottium – ah! – there we have gold.”
He drew forth the crucible, and there glowed in it a little bead or globule of molten gold.
“I could have taken lead or mercury and by varying the process done the same thing with the gold series as well as the gold group,” he said, regarding the globule with obvious pride. “And I can put this gold back and bring it out copper or hydrogen, or better yet, can advance it instead of cause it to decay, and can get a radioactive element which I have named morganium – after my first name, Morgan Prescott. Morganium is a radioactive element next in the series to radium and much more active. Come closer and examine the gold.”
Kennedy shook his head as if perfectly satisfied to accept the result. As for me I knew not what to think. It was all so plausible and there was the bead of gold, too, that I turned to Craig for enlightenment. Was he convinced? His face was inscrutable.
But as I looked I could see that Kennedy had been holding concealed in the palm of his hand a bit of what might be a mineral. From my position I could see the bit of mineral glowing, but Prescott could not.
“Might I ask,” interrupted Kennedy, “what that curious greenish or bluish light from the tube is composed of?”
Prescott eyed him keenly for an instant through his thick glasses. Craig had shifted his gaze from the bit of mineral in his own hand, but was not looking at the light. He seemed to be indifferently contemplating Prescott’s hand as it rested on the switch.
“That, sir,” replied Prescott slowly, “is an emanation due to this new force, protodyne, which I use. It is a manifestation of energy, sir, that may run changes not only through the whole gamut of the elements, but is capable of transforming the ether itself into matter, matter into life, and life into mind. It is the outward sign of the unity of nature, the – “
“The means by which you secure the curious telepagrams I have heard of?” inquired Kennedy eagerly.
Prescott looked at him sharply, and for a moment I thought his face seemed to change from a livid white to an apoplectic red, although it may have been only the play of the weird light. When he spoke it was with no show of even suppressed surprise.
“Yes,” he answered calmly. “I see that you have heard something of them. I had a curious case a few days ago. I had hoped to interest a certain capitalist of high standing in this city. I had showed him just what I have showed you, and I think he was impressed by it. Then I thought to clinch the matter by a telepagram, but for some reason or other I failed to consult the forces I control as to the wisdom of doing so. Had I, I should have known better. But I went ahead in self-confidence and enthusiasm. I told him of a long banished daughter with whom, in his heart, he was really wishing to become reconciled but was too proud to say the word. He resented it. He started to stamp out of this room, but not before I had another telepagram which told of – a misfortune that was soon to overtake the old man himself. If he had given me a chance I might have saved him, at least have flashed a telepagram to that daughter myself, but he gave me no chance. He was gone.
