an apologetic cough came through the entrance to the laboratory. it was nearing one o'clock of the following day.
several minutes later it was repeated, to the intense annoyance of the scientist, who had left orders that he was not to be interrupted in his work under any circumstances.
at the third "ahem!" he raised his head and stared fixedly at the empty space between the doorjambs. the most determined optimist could not have spelled welcome in that look.
peter, advancing his neck around the corner until one eye met that of his master, withdrew it hastily.
"well, what is it?" came from the laboratory, in an irritated harsh voice.
peter, in the act of retreating on tiptoe, turned, and once more cocked a solitary eye around the door-jamb. this one feature had the beseeching look of a dog trying to convey by his expression that not for worlds would he have got in the way of your boot.
"beg pardon, sir, but there's a young—"
"won't see him!"
"but, sir, it's a young lady—"
[pg 53]
"i'm busy, get out!"
peter gulped desperately. "the young lady from—"
at this moment ralph pressed a button nearby, an electromagnet acted, and a heavy plate glass door slid down from above, almost brushing peter's melancholy countenance, terminating the conversation summarily.
having secured himself against further interruption ralph returned to the large glass box over which he had been working, and in which one could see, through greenish vapors, a dog, across whose heart was strapped a flat glass box filled with a metal-like substance.
the substance in the box was radium-k. radium, which had been known for centuries, had the curious property of giving out heat for thousands of years without disintegrating and without apparently obtaining energy from any outside source.
in 2009, anatole m610 b9, the great french physicist, found that radium obtained all its energy from the ether of space and proved that radium was one of the few substances having a very strong affinity for the ether. radium, he found, attracted the ether violently and the latter surging back and forward through the radium became charged electrically, presenting all the other well known phenomena.
anatole m610 b9 compared the action of radium on the ether with that of a magnet acting upon a piece of iron. he proved this theory by examining a piece of pure metallic radium in an etherless space, whereupon it lost all its characteristics and acted like a piece of ordinary metal.
radium-k, as used by ralph, was not pure radium, but an alloy composed of radium and argonium. this alloy[pg 54] exhibited all the usual phenomena of pure radium and produced great heat, but did not create burns on animal tissue. it could be handled freely and without danger.
the dog lying in the glass box had been "dead" for three years. just three years previous, in the presence of twenty noted scientists ralph 124c 41+ had exhibited a live dog and had proceeded to drain off all its blood till the dog was pronounced quite dead and its heart had stopped beating. thereupon he had refilled the empty blood vessels of the animal with a weak solution of radium-k bromide, and the large artery through which the solution was pumped into the body had been closed.
the flat box containing radium-k was then strapped over the dog's heart and it was placed in the large glass case. the latter was filled with permagatol, a green gas having the property of preserving animal tissue permanently and indefinitely. the purpose of the box containing radium-k was to keep the temperature of the dog's body at a fixed point.
after the case was completely filled with gas, the glass cover was sealed in such a manner that it was impossible to open the case without breaking the seals. the scientists had agreed to return after a lapse of three years to witness the opening of the box.
there were several delicate instruments inside the box and these were connected by means of wires to recording instruments on the side, and these ralph inspected twice each day. throughout the three years the "dead" dog had never stirred a muscle. his temperature had not varied 1/100 of a degree and his respiratory functions had shown no signs of life. to all intents and purposes the dog was "dead."
[pg 55]
the time was close at hand for the final stages of what ralph considered to be his greatest experiment. three years ago when he faced his fellow scientists at the end of the first stage of this work, he electrified them by announcing that he expected to prove that this dog, which they had all pronounced "dead," could be restored to life, unharmed, unchanged, with no more effects upon the dog's spirits, habits, and nature, than had the animal taken but a short nap.
for three years this experiment of ralph 124c 41+ had been the subject of innumerable scientific papers, had been discussed intermittently in the newspapers and the date of the final phase of the great experiment was fixed in the mind of every human being on the planet.
if the experiment succeeded it meant the prolongation of human life over greater periods of the earth's history than had ever been possible. it meant that premature death except through accident would be ended.
would he succeed? had he attempted the impossible? was he challenging nature to a combat only to be worsted?
these thoughts obtruded themselves into his consciousness as he began the preparations for the great test of the afternoon. he pumped out the permagatol from the box until the green vapor had completely disappeared. with infinite care he then forced a small quantity of oxygen into the box. the instruments recording the action of the respiratory organs indicated that the oxygen reaching the dog's lungs had stimulated respiration.
this being all he could do for the present, he pressed the button that raised the glass barrier, and summoned peter by means of another button.
[pg 56]
that individual, looking a trifle more melancholy than usual, responded at once.
"well my boy," said ralph good-humoredly, "the stage is all set for the experiment that will set the whole world by the ears.—but you don't look happy, peter. what's troubling your dear old soul?"
peter, whose feelings had evidently been lacerated when the door had been lowered in his face, replied with heavy dignity.
"beg pardon, sir, but the young lady is still waiting."
"what young lady?" asked ralph.
"the young lady from switzerland, sir."
"the—which?"
"the young lady from switzerland, sir, and her father, sir. they've been waiting half an hour."
if a bomb had exploded that instant ralph could not have been more astounded.
"she's here—and you didn't call me? peter, there are times when i am tempted to throw you out—"
"pardon sir," replied peter firmly, "i made bold to assume that you might be interested in the young lady's arrival, and presumed to step into the laboratory to so inform—"
but his master had gone, shedding his laboratory smock as he went. peter, gathering his dignity about him as a garment, reached the doorway in time to see the elevator slide downwards out of sight.
and in it, ralph, his heart thumping in a most undignified way, was acting more like a schoolboy than a master of science. he twitched at his tie with one hand and smoothed his hair with the other, peering into the elevator's little mirror anxiously. discovering a smudge on[pg 57] his cheek he checked the car between floors while he wiped away the spot with his handkerchief.
when he reached the reception room he sprang from the elevator eagerly and hurried in. seated by one of the windows were alice 212b 423 and her father. both turned as he entered, and the girl rose to her feet and with a charming gesture held out both hands.
"we just had to come," she said prettily, and in perfect english. "you didn't give us an opportunity to thank you yesterday, and anyhow, we felt that telephot thanks were not nearly so nice. that is, father thought we really ought to come in person—of course, i did, too. i wanted to see you ever so much"—she broke off, and then, realizing the implication of her words, went on hastily with reddened cheeks and downcast eyes, "i mean, to—to thank you, you know."
"it was wonderful of you," he declared still holding her two hands, and utterly unmindful of the fact that she was gently trying to disengage them. indeed, he was not conscious of anyone or anything but her, until the voice of her father brought him to the realization that there was someone else in the room.
"we need no introduction i think," said the gentleman, "but i am james 212b 422 and i must ask you to pardon our intrusion upon a busy scientist's time, but i felt that we should come personally to thank you for the great service you have done us both. she is my one daughter, sir, and i love her dearly—dearly—"
"i can quite understand that," said ralph with an unconscious ardor that caused alice, who had completely recovered from her momentary confusion, to dimple and blush delightfully.
[pg 58]
"i'm afraid, father dear," she said, "that we are keeping a busy man too long. your man," she added, turning to ralph, "said you were engaged in a wonderful experiment, and could not be disturbed."
"busy? not at all," said ralph gracelessly. "you should not have been kept waiting one moment, and i am very indignant with peter for not breaking down the door. he should have known, when he saw you, that you were not to wait."
"oh, please, don't scold him because of me," said alice, not, however, at all displeased with the implied compliment.
"i didn't know yesterday that you spoke english," he said, "so i used the language-rectifier, but i see that you speak it perfectly. that is a great relief to me, i assure you, for i speak french very indifferently. but tell me," he continued, "how did you get here so soon? the afternoon transatlantic aeroliner is not due yet, and it can hardly be twenty-four hours since you left switzerland."
"we had the honor of being the first passengers to arrive by means of the new subatlantic tube," said james 212b 422. "as you are doubtless aware, the regular passenger service opens next week, but being one of the consulting engineers of the new electromagnetic tube, my daughter and i were permitted to make the first trip westward. we made it in perfect safety, although it was a little risky, as some small portions of the tube are not entirely completed."
"and we were so anxious to get here as quickly as possible," broke in alice with a glance at ralph.
"but you shouldn't have risked your lives, in an untested tube," he exclaimed. and then, the scientist in him[pg 59] to the front: "tell me all about this new tube. busy with my own work i have not followed its progress closely enough to know all its details."
"it has been most interesting work," said james 212b 422, "and we regard it as quite an achievement in electrical engineering. the new tube runs in a straight line between new york and brest, france. if the tube were to run straight along the bottom of the ocean the distance between the two points would be from 3600 to 3700 miles due to the curvature of the earth. for this reason the tube was pushed straight through the earth, thereby making the distance only 3470 miles.
"you will understand it better by examining this chart," and unfolding a plan, he proceeded to elaborate on the finer points of the tube construction. "the greatest trouble," he went on, "our engineers experienced near the middle of the tube; this point is 450 miles nearer the center of the earth and the heat became very marked. it was necessary to install large liquid-air plants at several points in the tube to reduce the heat, and now as you ride through no heat is noticed.
"we boarded the spacious steel car, which resembles a thick cigar, at brest last night at midnight, and arrived at the new york terminal at noon today. there was only one stop, a few hundred miles out from brest, because of several short-circuited electromagnets.
"there are no wheels to the tube car and it is propelled by magnetism only. at each three hundred feet is stationed a powerful tubular electromagnet, about thirty feet long, through which the tube car passes. each electromagnet exerts a tremendous pull upon the car three hundred feet away, this being the only steel object, and the[pg 60] car rushes toward the electromagnet with a tremendous speed. when the car is only two feet away from this electromagnet, the current is cut off automatically by the car itself, the latter plunging through the open space of the magnet coil, only to be influenced now by the next electromagnet, three hundred feet distant.

"the momentum acquired by the pull of the former electromagnet propels the car with ever-increasing speed, and by the time it has passed through twenty-five electromagnets it has reached the speed of three hundred[pg 61] miles an hour. it then continues at a steady pace till the end of the journey.
"as the car is held suspended entirely by magnetism, there is practically no friction whatever, as there are no wheels or rails. the only friction is from the air, and in order that this may not heat the car it is equipped with a double wall, the space between the inner and outer walls being a vacuum. consequently the temperature inside is comfortable at all times. once inside the car, we retired and slept as soundly as in our swinging beds at home. there were no shocks, no noise, no rocking—all in all the trip was so delightful, that i must say the new tube is a decided success!"
"fine, fine," said ralph enthusiastically. "this new tube is going to revolutionize intercontinental travel. i suppose it won't be long now before we will regard our tedious twenty-four hour journeys as things of the past. tell me," turning to alice who had been an interested listener, "how did the trip impress you?"
"oh," she exclaimed eagerly, "it was delightful! so smooth and fast! i was so excited. really, it was over too soon."
as she spoke ralph watched her with keen interest. here was a girl who attracted him. beneath the vivacity that so fascinated him he sensed the strength of her character, and the depth of her mind.
"i am so glad to be in new york," she was saying. "do you know, this is my first visit here for ages. why, the last time i can just barely remember, i was such a little girl. father has been promising me a trip for years," with a laughingly reproachful glance at him, "but it took an avalanche to get us started."
[pg 62]
"i'm afraid i've been a neglectful father of late years," said her father, "but my work has kept me tied pretty close to home. i, too, am pleased to be here once more, and my visit promises to be doubly interesting, for i understand that your great dog experiment will be completed today. i am looking forward to receiving the earliest reports of it at the hotel."
"but i can't permit you to spend your days here in a hotel," protested ralph. "of course you must both be my guests. yes, yes," as they seemed about to demur, "i won't take no for an answer. i am counting on showing you new york, and, as for my experiment, it will give me great pleasure to have you both present in my laboratory this afternoon at four."
he pressed a button. "peter will show you to your rooms, and i will send some one for your luggage."
"you are more than kind," said james. "this is quite unexpected, but none the less delightful. as to attending the meeting in your laboratory this afternoon, it is an honor, sir, that i appreciate deeply."
at this moment peter stepped from the elevator and ralph, after giving him instructions to show his guests to their apartment, and directions as to their bags, escorted them to the car and returned to the laboratory.
promptly at four, ralph greeted a notable group of fellow scientists, who had come from all corners of the planet to witness the completion of the famous "dead-alive dog" experiment. a host of reporters lined the walls. alice and her father were seated near ralph.
a number of the twenty scientists who had witnessed[pg 63] the beginning of the experiment three years before were dubiously contemplating the glass box, and one or two of the reporters, unawed by the personages in the laboratory, seven of whom were "plus" men, seemed to find much covert amusement in the whole affair.
finally, when all of the preparations were completed, and ralph's two assistants had stationed themselves beside the glass box containing the body, the young scientist addressed the gathering.
"ladies and gentlemen," he said, "you have come here to witness the final phase of my dog experiment. the preliminary phases you observed three years ago this day in this room. the seals you put in place are intact, and you may see them for yourselves, untouched as you left them.
"as i explained three years ago i formulated the theory that a well preserved animal, though dead to all intents and purposes, could be revived, or new life given to it, provided the body had not undergone decomposition; and also provided that none of the organs had suffered in the least.
"i found that the rare gas permagatol would conserve animal tissue and animal organs indefinitely; when it is used in conjunction with a weak solution of radium-k bromide, mixed with antiseptic salts, no part of an animal body would undergo any change for many years.
"i also found that the body would have to be kept at a fixed temperature and this was possible by the use of radium-k alloy. i am now ready to prove my theory."
he signaled to his assistants, and with their aid, the seals were broken and the glass cover of the case removed.
[pg 64]
a profound silence prevailed. every eye was focussed on the dog and many of those present found it difficult to remain seated.
ralph coolly and deliberately freed the dog of his bandages and attachments and placed him on an operating table in plain view of everyone.
from then on he and his aides moved rapidly. first the dead dog's artery was opened and the radium-k bromide solution drained off. a young goat was brought in and strapped on the table, and in a very few seconds one of its arteries had been opened and connected to the dead dog's main artery. in less than a minute the dog's body was full of fresh warm blood and immediately efforts were made to bring the dog back to life.
oxygen was freely administered and the heart was artificially pulsated by means of an electrical vibratory apparatus.
at the same time one of the assistants had trained a vacuum tube on the dog's head and its cathode shot the powerful f-9-rays into the animal's brain. no sooner had these rays, which are among the most powerful brain stimulants, been trained on the dog than he began to show weak signs of life. one of the hind legs was drawn up with a jerk as if in a fit. then came a faint heave of the chest, followed by a weak attempt to breathe.
a few minutes later the body seemed to contract and a shiver ran through it from head to tail. a deep respiration followed, and the animal opened its eyes as if awakening from a long sleep.
in a few minutes more the dog was lying on its paws and licking up milk when ralph turned to the group and said:
[pg 65]
"gentlemen, the experiment is concluded and i believe the condition of the animal at this moment establishes sufficient proof of my theory."
as the reporters eagerly dashed from the laboratory to get to the nearest telephot in order to communicate the news to the waiting world the scientists gathered around ralph and one of them, a white haired old man considered to be the dean of the "plus" men, voiced the sentiment of the entire group.
"ralph, this is one of the greatest gifts that science has brought to humanity. for what you have done with a dog, you can do with a human being. i only regret for myself that you had not lived and conducted this experiment when i was a young man, that i might have, from time to time, lived in suspended animation from century to century, and from generation to generation as it will now be possible for human beings to do."
the vista opened up by the results of this experiment in the minds of the other scientists had dazed them and it was with the most perfunctory good-byes that they left the scene of the experiment, enveloped with their thoughts of the future.
tired and exhausted by the nervous strain of the afternoon ralph, a few minutes later, lay down on his bed for a few hours' rest. but as he closed his eyes there came to him a vivid picture of a pair of warm dark eyes, radiating admiration, trust and something more that aroused an emotion he had never before experienced.
