Two miles west of the village of Laketon there lived an aged recluse who was known only as Old Crompton. As far back as the villagers could remember he had visited the town regularly twice a month, each time tottering his lonely way homeward with a load of provisions. He appeared to be well supplied with funds, but purchased sparingly as became a miserly hermit. And so vicious was his tongue that few cared to converse with him, even the young hoodlums of the town hesitating to harass him with the banter usually accorded the other bizarre characters of the streets.

The oldest inhabitants knew nothing of his past history, and they had long since lost their curiosity in the matter. He was a fixture, as was the old town hall with its surrounding park. His lonely cabin was shunned by all who chanced to pass along the old dirt road that led through the woods to nowhere and was rarely used.

His only extravagance was in the matter of books, and the village book store profited considerably by his purchases. But, at the instigation of Cass Harmon, the bookseller, it was whispered about that Old Crompton was a believer in the black art--that he had made a pact with the devil himself and was leagued with him and his imps. For the books he bought were strange ones; ancient volumes that Cass must needs order from New York or Chicago and that cost as much as ten and even fifteen dollars a copy; translations of the writings of the alchemists and astrologers and philosophers of the dark ages.

It was no wonder Old Crompton was looked at askance by the simple-living and deeply religious natives of the small Pennsylvania town.

But there came a day when the hermit was to have a neighbor, and the town buzzed with excited speculation as to what would happen.

The property across the road from Old Crompton’s hut belonged to Alton Forsythe, Laketon’s wealthiest resident--hundreds of acres of scrubby woodland that he considered well nigh worthless. But Tom Forsythe, the only son, had returned from college and his ambitions were of a nature strange to his townspeople and utterly incomprehensible to his father. Something vague about biology and chemical experiments and the like is what he spoke of, and, when his parents objected on the grounds of possible explosions and other weird accidents, he prevailed upon his father to have a secluded laboratory built for him in the woods.

When the workmen started the small frame structure not a quarter of a mile from his own hut, Old Crompton was furious. He raged and stormed, but to no avail. Tom Forsythe had his heart set on the project and he was somewhat of a successful debater himself. The fire that flashed from his cold gray eyes matched that from the pale blue ones of the elderly anchorite. And the law was on his side.

So the building was completed and Tom Forsythe moved in, bag and baggage.

For more than a year the hermit studiously avoided his neighbor, though, truth to tell, this required very little effort. For Tom Forsythe became almost as much of a recluse as his predecessor, remaining indoors for days at a time and visiting the home of his people scarcely oftener than Old Crompton visited the village. He too became the target of village gossip and his name was ere long linked with that of the old man in similar animadversion. But he cared naught for the opinions of his townspeople nor for the dark looks of suspicion that greeted him on his rare appearances in the public places. His chosen work engrossed him so deeply that all else counted for nothing. His parents remonstrated with him in vain. Tom laughed away their recriminations and fears, continuing with his labors more strenuously than ever. He never troubled his mind over the nearness of Old Crompton’s hut, the existence of which he hardly noticed or considered.

It so happened one day that the old man’s curiosity got the better of him and Tom caught him prowling about on his property, peering wonderingly at the many rabbit hutches, chicken coops, dove cotes and the like which cluttered the space to the rear of the laboratory.

Seeing that he was discovered, the old man wrinkled his face into a toothless grin of conciliation.

“Just looking over your place, Forsythe,” he said. “Sorry about the fuss I made when you built the house. But I’m an old man, you know, and changes are unwelcome. Now I have forgotten my objections and would like to be friends. Can we?”

Tom peered searchingly into the flinty eyes that were set so deeply in the wrinkled, leathery countenance. He suspected an ulterior motive, but could not find it within him to turn the old fellow down.

“Why--I guess so, Crompton,” he hesitated: “I have nothing against you, but I came here for seclusion and I’ll not have anyone bothering me in my work.”

“I’ll not bother you, young man. But I’m fond of pets and I see you have many of them here; guinea pigs, chickens, pigeons, and rabbits. Would you mind if I make friends with some of them?”

“They’re not pets,” answered Tom dryly, “they are material for use in my experiments. But you may amuse yourself with them if you wish.”

“You mean that you cut them up--kill them, perhaps?”

“Not that. But I sometimes change them in physical form, sometimes cause them to become of huge size, sometimes produce pigmy offspring of normal animals.”

“Don’t they suffer?”

“Very seldom, though occasionally a subject dies. But the benefit that will accrue to mankind is well worth the slight inconvenience to the dumb creatures and the infrequent loss of their lives.”

Old Crompton regarded him dubiously. “You are trying to find?” he interrogated.

“The secret of life!” Tom Forsythe’s eyes took on the stare of fanaticism. “Before I have finished I shall know the nature of the vital force--how to produce it. I shall prolong human life indefinitely; create artificial life. And the solution is more closely approached with each passing day.”

The hermit blinked in pretended mystification. But he understood perfectly, and he bitterly envied the younger man’s knowledge and ability that enabled him to delve into the mysteries of nature which had always been so attractive to his own mind. And somehow, he acquired a sudden deep hatred of the coolly confident young man who spoke so positively of accomplishing the impossible.

During the winter months that followed, the strange acquaintance progressed but little. Tom did not invite his neighbor to visit him, nor did Old Crompton go out of his way to impose his presence on the younger man, though each spoke pleasantly enough to the other on the few occasions when they happened to meet.

With the coming of spring they encountered one another more frequently, and Tom found considerable of interest in the quaint, borrowed philosophy of the gloomy old man. Old Crompton, of course, was desperately interested in the things that were hidden in Tom’s laboratory, but he never requested permission to see them. He hid his real feelings extremely well and was apparently content to spend as much time as possible with the feathered and furred subjects for experiment, being very careful not to incur Tom’s displeasure by displaying too great interest in the laboratory itself.

Then there came a day in early summer when an accident served to draw the two men closer together, and Old Crompton’s long-sought opportunity followed.

He was starting for the village when, from down the road, there came a series of tremendous squawkings, then a bellow of dismay in the voice of his young neighbor. He turned quickly and was astonished at the sight of a monstrous rooster which had escaped and was headed straight for him with head down and wings fluttering wildly. Tom followed close behind, but was unable to catch the darting monster. And monster it was, for this rooster stood no less than three feet in height and appeared more ferocious than a large turkey. Old Crompton had his shopping bag, a large one of burlap which he always carried to town, and he summoned enough courage to throw it over the head of the screeching, over-sized fowl. So tangled did the panic-stricken bird become that it was a comparatively simple matter to effect his capture, and the old man rose to his feet triumphant with the bag securely closed over the struggling captive.

“Thanks,” panted Tom, when he drew alongside. “I should never have caught him, and his appearance at large might have caused me a great deal of trouble--now of all times.”

“It’s all right, Forsythe,” smirked the old man. “Glad I was able to do it.”

Secretly he gloated, for he knew this occurrence would be an open sesame to that laboratory of Tom’s. And it proved to be just that.

A few nights later he was awakened by a vigorous thumping at his door, something that had never before occurred during his nearly sixty years occupancy of the tumbledown hut. The moon was high and he cautiously peeped from the window and saw that his late visitor was none other than young Forsythe.

“With you in a minute!” he shouted, hastily thrusting his rheumatic old limbs into his shabby trousers. “Now to see the inside of that laboratory,” he chuckled to himself.

It required but a moment to attire himself in the scanty raiment he wore during the warm months, but he could hear Tom muttering and impatiently pacing the flagstones before his door.

“What is it?” he asked, as he drew the bolt and emerged into the brilliant light of the moon.

“Success!” breathed Tom excitedly. “I have produced growing, living matter synthetically. More than this, I have learned the secret of the vital force--the spark of life. Immortality is within easy reach. Come and see for yourself.”

They quickly traversed the short distance to the two-story building which comprised Tom’s workshop and living quarters. The entire ground floor was taken up by the laboratory, and Old Crompton stared aghast at the wealth of equipment it contained. Furnaces there were, and retorts that reminded him of those pictured in the wood cuts in some of his musty books. Then there were complicated machines with many levers and dials mounted on their faces, and with huge glass bulbs of peculiar shape with coils of wire connecting to knoblike protuberances of their transparent walls. In the exact center of the great single room there was what appeared to be a dissecting table, with a brilliant light overhead and with two of the odd glass bulbs at either end. It was to this table that Tom led the excited old man.

“This is my perfected apparatus,” said Tom proudly, “and by its use I intend to create a new race of supermen, men and women who will always retain the vigor and strength of their youth and who can not die excepting by actual destruction of their bodies. Under the influence of the rays all bodily ailments vanish as if by magic, and organic defects are quickly corrected. Watch this now.”

He stepped to one of the many cages at the side of the room and returned with a wriggling cottontail in his hands. Old Compton watched anxiously as he picked a nickeled instrument from a tray of surgical appliances and requested his visitor to hold the protesting animal while he covered its head with a handkerchief.

“Ethyl chloride,” explained Tom, noting with amusement the look of distaste on the old man’s face. “We’ll just put him to sleep for a minute while I amputate a leg.”

The struggles of the rabbit quickly ceased when the spray soaked the handkerchief and the anaesthetic took effect. With a shining scalpel and a surgical saw, Tom speedily removed one of the forelegs of the animal and then he placed the limp body in the center of the table, removing the handkerchief from its head as he did so. At the end of the table there was a panel with its glittering array of switches and electrical instruments, and Old Crompton observed very closely the manipulations of the controls as Tom started the mechanism. With the ensuing hum of a motor-generator from a corner of the room, the four bulbs adjacent to the table sprang into life, each glowing with a different color and each emitting a different vibratory note as it responded to the energy within.

“Keep an eye on Mr. Rabbit now,” admonished Tom.

From the body of the small animal there emanated an intangible though hazily visible aura as the combined effects of the rays grew in intensity. Old Crompton bent over the table and peered amazedly at the stump of the foreleg, from which blood no longer dripped. The stump was healing over! Yes--it seemed to elongate as one watched. A new limb was growing on to replace the old! Then the animal struggled once more, this time to regain consciousness. In a moment it was fully awake and, with a frightened hop, was off the table and hobbling about in search of a hiding place.

Tom Forsythe laughed. “Never knew what happened,” he exulted, “and excepting for the temporary limp is not inconvenienced at all. Even that will be gone in a couple of hours, for the new limb will be completely grown by that time.”

“But--but, Tom,” stammered the old man, “this is wonderful. How do you accomplish it?”

“Ha! Don’t think I’ll reveal my secret. But this much I will tell you: the life force generated by my apparatus stimulates a certain gland that’s normally inactive in warm blooded animals. This gland, when active, possesses the function of growing new members to the body to replace lost ones in much the same manner as this is done in case of the lobster and certain other crustaceans. Of course, the process is extremely rapid when the gland is stimulated by the vital rays from my tubes. But this is only one of the many wonders of the process. Here is something far more remarkable.”

He took from a large glass jar the body of a guinea pig, a body that was rigid in death.

“This guinea pig,” he explained, “was suffocated twenty-four hours ago and is stone dead.”

“Suffocated?”

“Yes. But quite painlessly, I assure you. I merely removed the air from the jar with a vacuum pump and the little creature passed out of the picture very quickly. Now we’ll revive it.”

Old Crompton stretched forth a skinny hand to touch the dead animal, but withdrew it hastily when he felt the clammy rigidity of the body. There was no doubt as to the lifelessness of this specimen.

Tom placed the dead guinea pig on the spot where the rabbit had been subjected to the action of the rays. Again his visitor watched carefully as he manipulated the controls of the apparatus.

With the glow of the tubes and the ensuing haze of eery light that surrounded the little body, a marked change was apparent. The inanimate form relaxed suddenly and it seemed that the muscles pulsated with an accession of energy. Then one leg was stretched forth spasmodically. There was a convulsive heave as the lungs drew in a first long breath, and, with that, an astonished and very much alive rodent scrambled to its feet, blinking wondering eyes in the dazzling light.

“See? See?” shouted Tom, grasping Old Crompton by the arm in a viselike grip. “It is the secret of life and death! Aristocrats, plutocrats and beggars will beat a path to my door. But, never fear, I shall choose my subjects well. The name of Thomas Forsythe will yet be emblazoned in the Hall of Fame. I shall be master of the world!”

Old Crompton began to fear the glitter in the eyes of the gaunt young man who seemed suddenly to have become demented. And his envy and hatred of his talented host blazed anew as Forsythe gloried in the success of his efforts. Then he was struck with an idea and he affected his most ingratiating manner.

“It is a marvelous thing, Tom,” he said, “and is entirely beyond my poor comprehension. But I can see that it is all you say and more. Tell me--can you restore the youth of an aged person by these means?”

“Positively!” Tom did not catch the eager note in the old man’s voice. Rather he took the question as an inquiry into the further marvels of his process. “Here,” he continued, enthusiastically, “I’ll prove that to you also. My dog Spot is around the place somewhere. And he is a decrepit old hound, blind, lame and toothless. You’ve probably seen him with me.”

He rushed to the stairs and whistled. There was an answering yelp from above and the pad of uncertain paws on the bare wooden steps. A dejected old beagle blundered into the room, dragging a crippled hind leg as he fawned upon his master, who stretched forth a hand to pat the unsteady head.

“Guess Spot is old enough for the test,” laughed Tom, “and I have been meaning to restore him to his youthful vigor, anyway. No time like the present.”

He led his trembling pet to the table of the remarkable tubes and lifted him to its surface. The poor old beast lay trustingly where he was placed, quiet, save for his husky asthmatic breathing.

“Hold him, Crompton,” directed Tom as he pulled the starting lever of his apparatus.

And Old Crompton watched in fascinated anticipation as the ethereal luminosity bathed the dog’s body in response to the action of the four rays. Somewhat vaguely it came to him that the baggy flesh of his own wrinkled hands took on a new firmness and color where they reposed on the animal’s back. Young Forsythe grinned triumphantly as Spot’s breathing became more regular and the rasp gradually left it. Then the dog whined in pleasure and wagged his tail with increasing vigor. Suddenly he raised his head, perked his ears in astonishment and looked his master straight in the face with eyes that saw once more. The low throat cry rose to a full and joyous bark. He sprang to his feet from under the restraining hands and jumped to the floor in a lithe-muscled leap that carried him half way across the room. He capered about with the abandon of a puppy, making extremely active use of four sound limbs.

“Why--why, Forsythe,” stammered the hermit, “it’s absolutely incredible. Tell me--tell me--what is this remarkable force?”

His host laughed gleefully. “You probably wouldn’t understand it anyway, but I’ll tell you. It is as simple as the nose on your face. The spark of life, the vital force, is merely an extremely complicated electrical manifestation which I have been able to duplicate artificially. This spark or force is all that distinguishes living from inanimate matter, and in living beings the force gradually decreases in power as the years pass, causing loss of health and strength. The chemical composition of bones and tissue alters, joints become stiff, muscles atrophied, and bones brittle. By recharging, as it were, with the vital force, the gland action is intensified, youth and strength is renewed. By repeating the process every ten or fifteen years the same degree of vigor can be maintained indefinitely. Mankind will become immortal. That is why I say I am to be master of the world.”

For the moment Old Crompton forgot his jealous hatred in the enthusiasm with which he was imbued. “Tom--Tom,” he pleaded in his excitement, “use me as a subject. Renew my youth. My life has been a sad one and a lonely one, but I would that I might live it over. I should make of it a far different one--something worth while. See, I am ready.”

He sat on the edge of the gleaming table and made as if to lie down on its gleaming surface. But his young host only stared at him in open amusement.

“What? You?” he sneered, unfeelingly. “Why, you old fossil! I told you I would choose my subjects carefully. They are to be people of standing and wealth, who can contribute to the fame and fortune of one Thomas Forsythe.”

“But Tom, I have money,” Old Crompton begged. But when he saw the hard mirth in the younger man’s eyes, his old animosity flamed anew and he sprang from his position and shook a skinny forefinger in Tom’s face.

“Don’t do that to me, you old fool!” shouted Tom, “and get out of here. Think I’d waste current on an old cadger like you? I guess not! Now get out. Get out, I say!”

Then the old anchorite saw red. Something seemed to snap in his soured old brain. He found himself kicking and biting and punching at his host, who backed away from the furious onslaught in surprise. Then Tom tripped over a wire and fell to the floor with a force that rattled the windows, his ferocious little adversary on top. The younger man lay still where he had fallen, a trickle of blood showing at his temple.

“My God! I’ve killed him!” gasped the old man.

With trembling fingers he opened Tom’s shirt and listened for his heartbeats. Panic-stricken, he rubbed the young man’s wrists, slapped his cheeks, and ran for water to dash in his face. But all efforts to revive him proved futile, and then, in awful fear, Old Crompton dashed into the night, the dog Spot snapping at his heels as he ran.

Hours later the stooped figure of a shabby old man might have been seen stealthily re-entering the lonely workshop where the lights still burned brightly. Tom Forsythe lay rigid in the position in which Old Crompton had left him, and the dog growled menacingly.

Averting his gaze and circling wide of the body, Old Crompton made for the table of the marvelous rays. In minute detail he recalled every move made by Tom in starting and adjusting the apparatus to produce the incredible results he had witnessed. Not a moment was to be wasted now. Already he had hesitated too long, for soon would come the dawn and possible discovery of his crime. But the invention of his victim would save him from the long arm of the law, for, with youth restored, Old Crompton would cease to exist and a new life would open its doors to the starved soul of the hermit. Hermit, indeed! He would begin life anew, an active man with youthful vigor and ambition. Under an assumed name he would travel abroad, would enjoy life, and would later become a successful man of affairs. He had enough money, he told himself. And the police would never find Old Crompton, the murderer of Tom Forsythe! He deposited his small traveling bag on the floor and fingered the controls of Tom’s apparatus.

He threw the starting switch confidently and grinned in satisfaction as the answering whine of the motor-generator came to his ears. One by one he carefully made the adjustments in exactly the manner followed by the now silenced discoverer of the process. Everything operated precisely as it had during the preceding experiments. Odd that he should have anticipated some such necessity! But something had told him to observe Tom’s movements carefully, and now he rejoiced in the fact that his intuition had led him aright. Painfully he climbed to the table top and stretched his aching body in the warm light of the four huge tubes. His exertions during the struggle with Tom were beginning to tell on him. But the soreness and stiffness of feeble muscles and stubborn joints would soon be but a memory. His pulses quickened at the thought and he breathed deep in a sudden feeling of unaccustomed well-being.
