He took a pencil and struck a sharp blow on the table. "There you have a single blow," he said, "just one isolated noise. Now if I strike this tuning fork you have a vibrating note. In other words, a succession of blows or wave vibrations of a certain kind affects the ear and we call it sound, just as a succession of other wave vibrations affects the retina and we have sight. If a moving picture moves slower than a certain number of pictures a minute you see the separate pictures; faster it is one moving picture.
"Now as we increase the rapidity of wave vibration and decrease the wave length we pa.s.s from sound waves to heat waves or what are known as the infra-red waves, those which lie below the red in the spectrum of light. Next we come to light, which is composed of the seven colours as you know from seeing them resolved in a prism. After that are what are known as the ultra-violet rays, which lie beyond the violet of white light. We also have electric waves, the waves of the alternating current, and shorter still we find the Hertzian waves, which are used in wireless. We have only begun to know of X-rays and the alpha, beta, and gamma rays from them, of radium, radioactivity, and finally of this new force which I have discovered and call "protodyne," the original force.
"In short, we find in the universe Matter, Force, and Ether. Matter is simply ether in motion, is composed of corpuscles, electrically charged ions, or electrons, moving units of negative electricity about one one-thousandth part of the hydrogen atom. Matter is made up of electricity and nothing but electricity. Let us see what that leads to.
You are acquainted with Mendeleeff"s periodic table?"
He drew forth a huge chart on which all the eighty or so elements were arranged in eight groups or octaves and twelve series. Selecting one, he placed his finger on the letters "Au," under which was written the number, 197.2. I wondered what the mystic letters and figures meant.
"That," he explained, "is the scientific name for the element gold and the figure is its atomic weight. You will see," he added, pointing down the second vertical column on the chart, "that gold belongs to the hydrogen group--hydrogen, lithium, sodium, pota.s.sium, copper, rubidium, silver, caesium, then two blank s.p.a.ces for elements yet to be discovered to science, then gold, and finally another unknown element."
Running his finger along the eleventh, horizontal series, he, continued: "The gold series--not the group--reads gold, mercury, thallium, lead, bis.m.u.th, and other elements known only to myself. For the known elements, however, these groups and series are now perfectly recognised by all scientists; they are determined by the fixed weight of the atom, and there is a close approximation to regularity.
"This twelfth series is interesting. So far only radium, thorium, and uranium are generally known. We know that the radioactive elements are constantly breaking down, and one often hears uranium, for instance, called the "parent" of radium. Radium also gives off an emanation, and among its products is helium, quite another element. Thus the trans.m.u.tation of matter is well known within certain bounds to all scientists to-day like yourself, Professor Kennedy. It has even been rumoured but never proved that copper has been transformed into lithium--both members of the hydrogen-gold group, you will observe.
Copper to lithium is going backward, so to speak. It has remained for me to devise this protodyne apparatus by which I can reverse that process of decay and go forward in the table, so to put it--can change lithium into copper and copper into gold. I can create and destroy matter by protodyne."
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 gla.s.ses.
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.
"I do not know precisely what happened after that, but in some way this man found his daughter, and to-day she is living with him. As for my hopes of getting a.s.sistance from him, I lost them from the moment when I made my initial mistake of telling him something distasteful. The daughter hates me and I hate her. I have learned that she never ceases advising the old man against all schemes for investment except those bearing moderate interest and readily realised on. Dr. Burnham--I see you know him--has been superseded by another doctor, I believe. Well, well, I am through with that incident. I must get a.s.sistance from other sources. The old man, I think, would have tricked me out of the fruits of my discovery anyhow. Perhaps I am fortunate. Who knows?"
A knock at the door cut him short. Prescott opened it, and a messenger boy stood there. "Is Professor Kennedy here?" he inquired.
Craig motioned to the boy, signed for the message, and tore it open.
"It is from Dr. Burnham," he exclaimed, handing the message to me.
"Mr. Haswell is dead," I read. "Looks to me like asphyxiation by gas or some other poison. Come immediately to his house. Burnham."
"You will pardon me," broke in Craig to Prescott, who was regarding us without the slightest trace of emotion, "but Mr. Haswell, the old man to whom I know you referred, is dead, and Dr. Burnham wishes to see me immediately. It was only yesterday that I saw Mr. Haswell and he seemed in pretty good health and spirits. Prescott, though there was no love lost between you and the old man, I would esteem it a great favour if you would accompany me to the house. You need not take any responsibility unless you desire."
His words were courteous enough, but Craig spoke in a tone of quiet authority which Prescott found it impossible to deny. Kennedy had already started to telephone to his own laboratory, describing a certain suitcase to one of his students and giving his directions. It was only a moment later that we were panting up the sloping street that led from the river front. In the excitement I scarcely noticed where we were going until we hurried up the steps to the Haswell house.
The aged caretaker met us at the door. She was in tears. Upstairs in the front room where we had first met the old man we found Dr. Burnham working frantically over him. It took only a minute to learn what had happened. The faithful Jane had noticed an odour of gas in the hall, had traced it to Mr. Haswell"s room, had found him unconscious, and instinctively, forgetting the new Dr. Scott, had rushed forth for Dr.
Burnham. Near the bed stood Grace Martin, pale but anxiously watching the efforts of the doctor to resuscitate the blue-faced man who was stretched cold and motionless on the bed.
Dr. Burnham paused in his efforts as we entered. "He is dead, all right," he whispered, aside. "I have tried everything I know to bring him back, but he is beyond help."
There was still a sickening odour of illuminating gas in the room, although the windows were now all open.
Kennedy, with provoking calmness in the excitement, turned from and ignored Dr. Burnham. "Have you summoned Dr. Scott?" he asked Mrs.
Martin.
"No," she replied, surprised. "Should I have done so?"
"Yes. Send Jame immediately. Mr. Prescott, will you kindly be seated for a few moments."
Taking off his coat, Kennedy advanced to the bed where the emaciated figure lay, cold and motionless. Craig knelt down at Mr. Haswell"s head and took the inert arms, raising them up until they were extended straight. Then he brought them down, folded upward at the elbow at the side. Again and again he tried this Sylvester method of inducing respiration, but with no more result than Dr. Burnham had secured. He turned the body over on its face and tried the new Schaefer method.
There seemed to be not a spark of life left.
"Dr. Scott is out," reported the maid breathlessly, "but they are trying to locate him from his office, and if they do they will send him around immediately."
A ring at the doorbell caused us to think that he had been found, but it proved to be the student to whom Kennedy had telephoned at his own laboratory. He was carrying a heavy suitcase and a small tank.
Kennedy opened the suitcase hastily and disclosed a little motor, some long tubes of rubber fitting into a small rubber cap, forceps, and other paraphernalia. The student quickly attached one tube to the little tank, while Kennedy grasped the tongue of the dead man with the forceps, pulled it up off the soft palate, and fitted the rubber cap snugly over his mouth and nose.
"This is the Draeger pulmotor," he explained as he worked, "devised to resuscitate persons who have died of electric shock, but actually found to be of more value in cases of asphyxiation. Start the motor."
The pulmotor began to pump. One could see the dead man"s chest rise as it was inflated with oxygen forced by the accordion bellows from the tank through one of the tubes into the lungs. Then it fell as the oxygen and the poisonous gas were slowly sucked out through the other tube. Again and again the process was repeated, about ten times a minute.
Dr. Burnham looked on in undisguised amazement. He had long since given up all hope. The man was dead, medically dead, as dead as ever was any gas victim at this stage on whom all the usual methods of resuscitation had been tried and had failed.
Still, minute after minute, Kennedy worked faithfully on, trying to discover some spark of life and to fan it into flame. At last, after what seemed to be a half-hour of unremitting effort, when the oxygen had long since been exhausted and only fresh air was being pumped into the lungs and out of them, there was a first faint glimmer of life in the heart and a touch of colour in the cheeks. Haswell was coming to.
Another half-hour found him muttering and rambling weakly.
"The letter--the letter," he moaned, rolling his glazed eyes about.
"Where is the letter? Send for Grace."
The moan was so audible that it was startling. It was like a voice from the grave. What did it all mean? Mrs. Martin was at his side in a moment.
"Father, father,--here I am--Grace. What do you want?"
The old man moved restlessly, feverishly, and pressed his trembling hand to his forehead as if trying to collect his thoughts. He was weak, but it was evident that he had been saved.
The pulmotor had been stopped. Craig threw the cap to his student to be packed up, and as he did so he remarked quietly, "I could wish that Dr.
Scott had been found. There are some matters here that might interest him."
