Kennedy had already telephoned to the Winslows and Miss Winslow had answered that Strong had returned from Boston. After a little parleying, the second visit to the laboratory was arranged and Miss Winslow was allowed to be present with her father, after Kennedy had been a.s.sured by Strong that the gruesome relics of the tragedy would be cleared away.
It was in the forenoon that we arrived with Borland and Lathrop. I could not help noticing the cordial manner with which Borland greeted Miss Winslow. There was something obtrusive even in his sympathy.
Strong, whom we met now for the first time, seemed rather suspicious of the presence of Borland and his chemist, but made an effort to talk freely without telling too much.
"Of course you know," commenced Strong after proper urging, "that it has long been the desire of chemists to synthesise rubber by a method that will make possible its cheap production on a large scale. In a general way I know what Mr. Cushing had done, but there are parts of the process which are covered in the patents applied for, of which I am not at liberty to speak yet."
"Where are the papers in the case, the doc.u.ments showing the application for the patent, for instance?" asked Kennedy.
"In the safe, sir," replied Strong.
Strong set to work on the combination which he had obtained from the safe deposit vault. I could see that Borland and Miss Winslow were talking in a low tone.
"Are you sure that it is a fact?" I overheard him ask, though I had no idea what they were talking about.
"As sure as I am that the Borland Rubber Works are a fact," she replied.
Craig also seemed to have overheard, for he turned quickly. Borland had taken out his penknife and was moistening the blade carefully preparing to cut into a piece Of the synthetic rubber. In spite of his expressed scepticism, I could see that he was eager to learn what the product was really like.
Strong, meanwhile, had opened the safe and was going over the papers. A low exclamation from him brought us around the little pile of doc.u.ments. He was holding a will in which nearly everything belonging to Cushing was left to Miss Winslow.
Not a word was said, although I noticed that Kennedy moved quickly to her side, fearing that the shock of the discovery might have a bad effect on her, but she took it with remarkable calmness. It was apparent that Cushing had taken the step of his own accord and had said nothing to her about it.
"What does anything amount to?" she said tremulously at last. "The dream is dead without him in it."
"Come," urged Kennedy gently. "This is enough for to-day."
An hour later we were speeding back to New York. Kennedy had no apparatus to work with out at Goodyear and could not improvise it.
Winslow agreed to keep us in touch with any new developments during the few hours that Craig felt it was necessary to leave the scene of action.
Back again in New York, Craig took a cab directly for his laboratory, leaving me marooned with instructions not to bother him for several hours. I employed the time in a little sleuthing on my own account, endeavouring to look up the records of those involved in the case. I did not discover much, except an interview that had been given at the time of the return of his expedition by Borland to the Star, in which he gave a graphic description of the dangers from disease that they had encountered.
I mention it because, though it did not impress me much when I read it, it at once leaped into my mind when the interminable hours were over and I rejoined Kennedy. He was bending over a new microscope.
"This is a rubber age, Walter," he began, "and the stories of men who have been interested in rubber often sound like fiction."
He slipped a slide under the microscope, looked at it and then motioned to me to do the same. "Here is a very peculiar culture which I have found in some of that blood," he commented. "The germs are much larger than bacteria and they can be seen with a comparatively low power microscope swiftly darting between the blood cells, brushing them aside, but not penetrating them as some parasites, like that of malaria, do. Besides, spectroscope tests show the presence of a rather well-known chemical in that blood."
"A poisoning, then?" I ventured. "Perhaps he suffered from the disease that many rubber workers get from the bisulphide of carbon. He must have done a good deal of vulcanising of his own rubber, you know."
"No," smiled Craig enigmatically, "it wasn"t that. It was an a.r.s.enic derivative. Here"s another thing. You remember the field gla.s.s I used?"
He had picked it up from the table and was pointing at a little hole in the side, that had escaped my notice before. "This is what you might call a right-angled camera. I point the gla.s.s out of the window and while you think I am looking through it I am really focusing it on you and taking your picture standing there beside me and out of my apparent line of vision. It would deceive the most wary."
Just then a long-distance call from Winslow told us that Borland had been to call on Miss Ruth and, in as kindly a way as could be, had offered her half a million dollars for her rights in the new patent. At once it flashed over me that he was trying to get control of and suppress the invention in the interests of his own company, a thing that has been done hundreds of times. Or could it all have been part of a conspiracy? And if it was his conspiracy, would he succeed in tempting his friend, Miss Winslow, to fall in with this glittering offer?
Kennedy evidently thought, also, that the time for action had come, for without a word he set to work packing his apparatus and we were again headed for Goodyear.
XVI
THE BLOOD TEST
We arrived late at night, or rather in the morning, but in spite of the late hour Kennedy was up early urging me to help him carry the stuff over to Cushing"s laboratory. By the middle of the morning he was ready and had me scouring about town collecting his audience, which consisted of the Winslows, Borland and Lathrop, Dr. Howe, Dr. Harris, Strong and myself. The laboratory was darkened and Kennedy took his place beside an electric moving picture apparatus.
The first picture was different from anything any of us had ever seen on a screen before. It seemed to be a ma.s.s of little dancing globules.
"This," explained Kennedy, "is what you would call an educational moving picture, I suppose. It shows normal blood corpuscles as they are in motion in the blood of a healthy man. Those little round cells are the red corpuscles and the larger irregular cells are the white corpuscles."
He stopped the film. The next picture was a sort of enlarged and elongated house fly, apparently, of sombre grey color, with a narrow body, thick proboscis and wings that overlapped like the blades of a pair of shears. "This," he went on, "is a picture of the now well known tse-tse fly found over a large area of Africa. It has a bite something like a horse-fly and is a perfect blood-sucker. Vast territories of thickly populated, fertile country near the sh.o.r.es of lakes and rivers are now depopulated as a result of the death-dealing bite of these flies, more deadly than the blood-sucking, vampirish ghosts with which, in the middle ages, people supposed night air to be inhabited. For this fly carries with it germs which it leaves in the blood of its victims, which I shall show next."
A new film started.
"Here is a picture of some blood so infected. Notice that worm-like sheath of undulating membrane terminating in a slender whip-like process by which it moves about. That thing wriggling about like a minute electric eel, always in motion, is known as the trypanosome.
"Isn"t this a marvellous picture? To see the micro-organism move, evolve and revolve in the midst of normal cells, uncoil and undulate in the fluids which they inhabit, to see them play hide and seek with the blood corpuscles and clumps of fibrin, turn, twist, and rotate as if in a cage, to see these deadly little trypanosomes moving back and forth in every direction displaying their delicate undulating membranes and shoving aside the blood cells that are in their way while by their side the leucocytes, or white corpuscles, lazily extend or retract their pseudopods of protoplasm. To see all this as it is shown before us here is to realise that we are in the presence of an unknown world, a world infinitesimally small, but as real and as complex as that about us.
With the cinematograph and the ultra-microscope we can see what no other forms of photography can reproduce.
"I have secured these pictures so that I can better ma.s.s up the evidence against a certain person in this room. For in the blood of one of you is now going on the fight which you have here seen portrayed by the picture machine. Notice how the blood corpuscles in this infected blood have lost their smooth, glossy appearance, become granular and incapable of nourishing the tissues. The trypanosomes are fighting with the normal blood cells. Here we have the lowest group of animal life, the protozoa, at work killing the highest, man."
Kennedy needed nothing more than the breathless stillness to convince him of the effectiveness of his method of presenting his case.
"Now," he resumed, "let us leave this blood-sucking, vampirish tse-tse fly for the moment. I have another revelation to make."
He laid down on the table under the lights, which now flashed up again, the little hollow silver cylinder.
"This little instrument," Kennedy explained, "which I have here is known as a canula, a little ca.n.a.l, for leading off blood from the veins of one person to another--in other words, blood transfusion. Modern doctors are proving themselves quite successful in its use.
"Of course, like everything, it has its own peculiar dangers. But the one point I wish to make is this: In the selection of a donor for transfusion, people fall into definite groups. Tests of blood must be made first to see whether it "agglutinates," and in this respect there are four cla.s.ses of persons. In our case this matter had to be neglected. For, gentlemen, there were two kinds of blood on that laboratory floor, and they do not agglutinate. This, in short, was what actually happened. An attempt was made to transfuse Cushing"s blood as donor to another person as recipient. A man suffering from the disease caught from the bite of the tse-tse fly--the deadly sleeping sickness so well known in Africa--has deliberately tried a form of robbery which I believe to be without parallel. He has stolen the blood of another!
"He stole it in a desperate attempt to stay an incurable disease. This man had used an a.r.s.enic compound called atoxyl, till his blood was filled with it and its effects on the trypanosomes nil. There was but one wild experiment more to try--the stolen blood of another."
Craig paused to let the horror of the crime sink into our minds.
"Some one in the party which went to look over the concession in the Congo contracted the sleeping sickness from the bites of those blood-sucking flies. That person has now reached the stage of insanity, and his blood is full of the germs and overloaded with atoxyl.
"Everything had been tried and had failed. He was doomed. He saw his fortune menaced by the discovery of the way to make synthetic rubber.
Life and money were at stake. One night, nerved up by a fit of insane fury, with a power far beyond what one would expect in his ordinary weakened condition, he saw a light in Cushing"s laboratory. He stole in stealthily. He seized the inventor with his momentarily superhuman strength and choked him. As they struggled he must have shoved a sponge soaked with ether and orange essence under his nose. Cushing went under.
"Resistance overcome by the anesthetic, he dragged the now insensible form to the work bench. Frantically he must have worked. He made an incision and exposed the radial artery, the pulse. Then he must have administered a local anesthetic to himself in his arm or leg. He secured a vein and pushed the cut end over this little canula. Then he fitted the artery of Cushing over that and the blood that was, perhaps, to save his life began flowing into his depleted veins.
"Who was this madman? I have watched the actions of those whom I suspected when they did not know they were being watched. I did it by using this neat little device which looks like a field gla.s.s, but is really a camera that takes pictures of things at right angles to the direction in which the gla.s.s seems to be pointed. One person, I found, had a wound on his leg, the wrapping of which he adjusted nervously when he thought no one was looking. He had difficulty in limping even a short distance to open a window."
Kennedy uncorked a bottle and the subtle odor of oranges mingled with ether stole through the room.
"Some one here will recognize that odour immediately. It is the new orange-essence vapour anesthetic, a mixture of essence of orange with ether and chloroform. The odour hidden by the orange which lingered in the laboratory, Mr. Winslow and Mr. Strong, was not isoprene, but really ether.
