The Master Key

Much as he would have enjoyed a day in the great metropolis of the Pacific slope, Rob dared not delay longer than to take a general view of the place, to note its handsome edifices and to wonder at the throng of Chinese inhabiting one section of the town.

These things were much more plainly and quickly viewed by Rob from above than by threading a way through the streets on foot; for he looked down upon the city as a bird does, and covered miles with a single glance.

Having satisfied his curiosity without attempting to alight, he turned to the southeast and followed the peninsula as far as Palo Alto, where he viewed the magnificent buildings of the university. Changing his course to the east, he soon reached Mount Hamilton, and, being attracted by the great tower of the Lick Observatory, he hovered over it until he found he had attracted the excited gaze of its inhabitants, who doubtless observed him very plainly through the big telescope.

But so unreal and seemingly impossible was the sight witnessed by the learned astronomers that they have never ventured to make the incident public, although long after the boy had darted away into the east they argued together concerning the marvelous and incomprehensible vision. Afterward they secretly engrossed the circumstance upon their records, but resolved never to mention it in public, lest their wisdom and veracity should be assailed by the skeptical.

Meantime Rob rose to a higher altitude, and sped swiftly across the great continent. By noon he sighted Chicago, and after a brief inspection of the place from the air determined to devote at least an hour to forming the acquaintance of this most wonderful and cosmopolitan city.

CHAPTER EIGHTEEN

A NARROW ESCAPE

The Auditorium Tower, where "the weather man" sits to flash his reports throughout the country, offered an inviting place for the boy to alight. He dropped quietly upon the roof of the great building and walked down the staircase until he reached the elevators, by means of which he descended to the ground floor without exciting special attention.

The eager rush and hurry of the people crowding the sidewalks impressed Rob with the idea that they were all behind time and were trying hard to catch up. He found it impossible to walk along comfortably without being elbowed and pushed from side to side; so a half hour's sight-seeing under such difficulties tired him greatly. It was a beautiful afternoon, and finding himself upon the Lake Front, Rob hunted up a vacant bench and sat down to rest.

Presently an elderly gentleman with a reserved and dignified appearance and dressed in black took a seat next to the boy and drew a magazine from his pocket. Rob saw that he opened it to an article on "The Progress of Modern Science," in which he seemed greatly interested.

After a time the boy remembered that he was hungry, not having eaten a tablet in more than twenty-four hours. So he took out the silver box and ate one of the small, round disks it contained.

"What are those?" inquired the old gentleman in a soft voice. "You are too young to be taking patent medicines."

"These are not medicines, exactly," answered the boy, with a smile. "They are Concentrated Food Tablets, stored with nourishment by means of electricity. One of them furnishes a person with food for an entire day."

The old gentleman stared at Rob a moment and then laid down his magazine and took the box in his hands, examining the tablets curiously.

"Are these patented?" he asked.

"No," said Rob; "they are unknown to any one but myself."

"I will give you a half million dollars for the recipe to make them," said the gentleman.

"I fear I must refuse your offer," returned Rob, with a laugh.

"I'll make it a million," said the gentleman, coolly.

Rob shook his head.

"Money can't buy the recipe," he said; "for I don't know it myself."

"Couldn't the tablets be chemically analyzed, and the secret discovered?" inquired the other.

"I don't know; but I'm not going to give any one the chance to try," declared the boy, firmly.

The old gentleman picked up his magazine without another word, and resumed his reading.

For amusement Rob took the Record of Events from his pocket and began looking at the scenes reflected from its polished plate.

Presently he became aware that the old gentleman was peering over his shoulder with intense interest. General Funston was just then engaged in capturing the rebel chief, Aguinaldo, and for a few moments both man and boy observed the occurrence with rapt attention. As the scene was replaced by one showing a secret tunnel of the Russian Nihilists, with the conspirators carrying dynamite to a recess underneath the palace of the Czar, the gentleman uttered a long sigh and asked:

"Will you sell that box?"

"No," answered Rob, shortly, and put it back into his pocket.

"I'll give you a million dollars to control the sale in Chicago alone," continued the gentleman, with an eager inflection in his smooth voice.

"You seem quite anxious to get rid of money," remarked Rob, carelessly. "How much are you worth?"

"Personally?"

"Yes."

"Nothing at all, young man. I am not offering you my own money. But with such inventions as you have exhibited I could easily secure millions of capital. Suppose we form a trust, and place them upon the market. We'll capitalize it for a hundred millions, and you can have a quarter of the stock – twenty-five millions. That would keep you from worrying about grocery bills."

"But I wouldn't need groceries if I had the tablets," said Rob, laughing.

"True enough! But you could take life easily and read your newspaper in comfort, without being in any hurry to get down town to business. Twenty-five millions would bring you a cozy little income, if properly invested."

"I don't see why one should read newspapers when the Record of Events shows all that is going on in the world," objected Rob.

"True, true! But what do you say to the proposition?"

"I must decline, with thanks. These inventions are not for sale."

The gentleman sighed and resumed his magazine, in which he became much absorbed.

Rob put on the Character Marking Spectacles and looked at him. The letters "E", "W" and "C" were plainly visible upon the composed, respectable looking brow of his companion.

"Evil, wise and cruel," reflected Rob, as he restored the spectacles to his pocket. "How easily such a man could impose upon people. To look at him one would think that butter wouldn't melt in his mouth!"

He decided to part company with this chance acquaintance and, rising from his seat, strolled leisurely up the walk. A moment later, on looking back, he discovered that the old gentleman had disappeared.

He walked down State Street to the river and back again, amused by the activity displayed in this busy section of the city. But the time he had allowed himself in Chicago had now expired, so he began looking around for some high building from the roof of which he could depart unnoticed.

This was not at all difficult, and selecting one of many stores he ascended by an elevator to the top floor and from there mounted an iron stairway leading to the flat roof. As he climbed this stairway he found himself followed by a pleasant looking young man, who also seemed desirous of viewing the city from the roof.

Annoyed at the inopportune intrusion, Rob's first thought was to go back to the street and try another building; but, upon reflecting that the young man was not likely to remain long and he would soon be alone, he decided to wait. So he walked to the edge of the roof and appeared to be interested in the scenery spread out below him.

"Fine view from here, ain't it?" said the young man, coming up to him and placing his hand carelessly upon the boy's shoulder.

"It is, indeed," replied Rob, leaning over the edge to look into the street.

As he spoke he felt himself gently but firmly pushed from behind and, losing his balance, he plunged headforemost from the roof and whirled through the intervening space toward the sidewalk far below.

Terrified though he was by the sudden disaster, the boy had still wit enough remaining to reach out his right hand and move the indicator of the machine upon his left wrist to the zero mark. Immediately he paused in his fearful flight and presently came to a stop at a distance of less than fifteen feet from the flagstones which had threatened to crush out his life.

As he stared downward, trying to recover his self-possession, he saw the old gentleman he had met on the Lake Front standing just below and looking at him with a half frightened, half curious expression in his eyes.

At once Rob saw through the whole plot to kill him and thus secure possession of his electrical devices. The young man upon the roof who had attempted to push him to his death was a confederate of the innocent appearing old gentleman, it seemed, and the latter had calmly awaited his fall to the pavement to seize the coveted treasures from his dead body. It was an awful idea, and Rob was more frightened than he had ever been before in his life – or ever has been since.

But now the shouts of a vast concourse of amazed spectators reached the boy's ears. He remembered that he was suspended in mid-air over the crowded street of a great city, while thousands of wondering eyes were fixed upon him.

So he quickly set the indicator to the word "up," and mounted sky-ward until the watchers below could scarcely see him. Then he fled away into the east, even yet shuddering with the horror of his recent escape from death and filled with disgust at the knowledge that there were people who held human life so lightly that they were willing to destroy it to further their own selfish ends.

"And the Demon wants such people as these to possess his electrical devices, which are as powerful to accomplish evil when in wrong hands as they are good!" thought the boy, resentfully. "This would be a fine world if Electric Tubes and Records of Events and Traveling Machines could be acquired by selfish and unprincipled persons!"

So unnerved was Rob by his recent experiences that he determined to make no more stops. However, he alighted at nightfall in the country, and slept upon the sweet hay in a farmer's barn.

But, early the next morning, before any one else was astir, he resumed his journey, and at precisely ten o'clock of this day, which was Saturday, he completed his flying trip around the world by alighting unobserved upon the well-trimmed lawn of his own home.

CHAPTER NINETEEN

ROB MAKES A RESOLUTION

When Rob opened the front door he came face to face with Nell, who gave an exclamation of joy and threw herself into his arms.

"Oh, Rob!" she cried, "I'm so glad you've come. We have all been dreadfully worried about you, and mother – "

"Well, what about mother?" inquired the boy, anxiously, as she paused.

"She's been very ill, Rob; and the doctor said to-day that unless we heard from you soon he would not be able to save her life. The uncertainty about you is killing her."

Rob stood stock still, all the eager joy of his return frozen into horror at the thought that he had caused his dear mother so much suffering.

"Where is she, Nell?" he asked, brokenly.

"In her room. Come; I'll take you to her."

Rob followed with beating heart, and soon was clasped close to his mother's breast.

"Oh, my boy – my dear boy!" she murmured, and then for very joy and love she was unable to say more, but held him tight and stroked his hair gently and kissed him again and again.

Rob said little, except to promise that he would never again leave home without her full consent and knowledge. But in his mind he contrasted the love and comfort that now surrounded him with the lonely and unnatural life he had been leading and, boy though he was in years, a mighty resolution that would have been creditable to an experienced man took firm root in his heart.

He was obliged to recount all his adventures to his mother and, although he made light of the dangers he had passed through, the story drew many sighs and shudders from her.

When luncheon time arrived he met his father, and Mr. Joslyn took occasion to reprove his son in strong language for running away from home and leaving them filled with anxiety as to his fate. However, when he saw how happy and improved in health his dear wife was at her boy's return, and when he had listened to Rob's manly confession of error and expressions of repentance, he speedily forgave the culprit and treated him as genially as ever.

Of course the whole story had to be repeated, his sisters listening this time with open eyes and ears and admiring their adventurous brother immensely. Even Mr. Joslyn could not help becoming profoundly interested, but he took care not to show any pride he might feel in his son's achievements.

When his father returned to his office Rob went to his own bed-chamber and sat for a long time by the window in deep thought. When at last he aroused himself, he found it was nearly four o'clock.

"The Demon will be here presently," he said, with a thrill of aversion, "and I must be in the workshop to receive him."

Silently he stole to the foot of the attic stairs and then paused to listen. The house seemed very quiet, but he could hear his mother's voice softly humming a cradle-song that she had sung to him when he was a baby.

He had been nervous and unsettled and a little fearful until then, but perhaps the sound of his mother's voice gave him courage, for he boldly ascended the stairs and entered the workshop, closing and locking the door behind him.

CHAPTER TWENTY

THE UNHAPPY FATE OF THE DEMON

Again the atmosphere quickened and pulsed with accumulating vibrations. Again the boy found himself aroused to eager expectancy. There was a whirl in the air; a crackling like distant musketry; a flash of dazzling light – and the Demon stood before him for the third time.

"I give you greetings!" said he, in a voice not unkindly.

"Good afternoon, Mr. Demon," answered the boy, bowing gravely.

"I see you have returned safely from your trip," continued the Apparition, cheerfully, "although at one time I thought you would be unable to escape. Indeed, unless I had knocked that tube from the rascally Turk's hand as he clambered to the top of the wall, I believe you would have been at the Yarkand oasis yet – either dead or alive, as chance might determine."

"Were you there?" asked Rob.

"To be sure. And I recovered the tube for you, without which you would have been helpless. But that is the only time I saw fit to interfere in any way."

"I'm afraid I did not get a chance to give many hints to inventors or scientists," said Rob.

"True, and I have deeply regretted it," replied the Demon. "But your unusual powers caused more astonishment and consternation than you, perhaps, imagined; for many saw you whom you were too busy to notice. As a result several able electricians are now thinking new thoughts along new lines, and some of them may soon give these or similar inventions to the world."

"You are satisfied, then?" asked Rob.

"As to that," returned the Demon, composedly, "I am not. But I have hopes that with the addition of the three marvelous devices I shall present you with to-day you will succeed in arousing so much popular interest in electrical inventions as to render me wholly satisfied with the result of this experiment."

Rob regarded the brilliant apparition with a solemn face, but made no answer.

"No living person," continued the Demon, "has ever before been favored with such comforting devices for the preservation and extension of human life as yourself. You seem quite unappreciative, it is true; but since our connection I have come to realize that you are but an ordinary boy, with many boyish limitations; so I do not condemn your foolish actions too harshly."

"That is kind of you," said Rob.

"To prove my friendliness," pursued the Demon, "I have brought, as the first of to-day's offerings, this Electro-Magnetic Restorer. You see it is shaped like a thin metal band, and is to be worn upon the brow, clasping at the back of the head. Its virtues surpass those of either the fabulous 'Fountain of Youth,' or the 'Elixir of Life,' so vainly sought for in past ages. For its wearer will instantly become free from any bodily disease or pain and will enjoy perfect health and vigor. In truth, so great are its powers that even the dead may be restored to life, provided the blood has not yet chilled. In presenting you with this appliance, I feel I am bestowing upon you the greatest blessing and most longed-for boon ever bequeathed to suffering humanity."

Here he held the slender, dull-colored metallic band toward the boy.

"Keep it," said Rob.

The Demon started, and gave him an odd look.

"What did you say?" he asked.

"I told you to keep it," answered Rob. "I don't want it."

The Demon staggered back as if he had been struck.

"Don't want it!" he gasped.

"No; I've had enough of your infernal inventions!" cried the boy, with sudden anger.

He unclasped the traveling machine from his wrist and laid it on the table beside the Demon.

"There's the thing that's responsible for most of my troubles," said he, bitterly. "What right has one person to fly through the air while all his fellow-creatures crawl over the earth's surface? And why should I be cut off from all the rest of the world because you have given me this confounded traveling machine? I didn't ask for it, and I won't keep it a moment longer. Give it to some one you hate more than you do me!"

The Demon stared aghast and turned his glittering eyes wonderingly from Rob to the traveling machine and back again, as if to be sure he had heard and seen aright.

"And here are your food tablets," continued the boy, placing the box upon the table. "I've only enjoyed one square meal since you gave them to me. They're all right to preserve life, of course, and answer the purpose for which they were made; but I don't believe nature ever intended us to exist upon such things, or we wouldn't have the sense of taste, which enables us to enjoy natural food. As long as I'm a human being I'm going to eat like a human being, so I've consumed my last Electrical Concentrated Food Tablet – and don't you forget it!"

The Demon sank into a chair, nerveless and limp, but still staring fearfully at the boy.

"And there's another of your unnatural devices," said Rob, putting the Automatic Record of Events upon the table beside the other things. "What right have you to capture vibrations that radiate from private and secret actions and discover them to others who have no business to know them? This would be a fine world if every body could peep into every one else's affairs, wouldn't it? And here is your Character Marker. Nice thing for a decent person to own, isn't it? Any one who would take advantage of such a sneaking invention as that would be worse than a thief! Oh, I've used them, of course, and I ought to be spanked for having been so mean and underhanded; but I'll never be guilty of looking through them again."

The Demon's face was frowning and indignant. He made a motion to rise, but thought better of it and sank back in his chair.

"As for the Garment of Protection," resumed the boy, after a pause, "I've worn it for the last time, and here it is, at your service. I'll put the Electric Tube with it. Not that these are such very bad things in themselves, but I'll have none of your magical contrivances. I'll say this, however: if all armies were equipped with Electrical Tubes instead of guns and swords the world would be spared a lot of misery and unnecessary bloodshed. Perhaps they will be, in time; but that time hasn't arrived yet."

"You might have hastened it," said the Demon, sternly, "if you had been wise enough to use your powers properly."

"That's just it," answered Rob. "I'm not wise enough. Nor is the majority of mankind wise enough to use such inventions as yours unselfishly and for the good of the world. If people were better, and every one had an equal show, it would be different."

For some moments the Demon sat quietly thinking. Finally the frown left his face and he said, with animation:

"I have other inventions, which you may use without any such qualms of conscience. The Electro-Magnetic Restorer I offered you would be a great boon to your race, and could not possibly do harm. And, besides this, I have brought you what I call the Illimitable Communicator. It is a simple electric device which will enable you, wherever you may be, to converse with people in any part of the world, without the use of such crude connections as wires. In fact, you may" —

"Stop!" cried Rob. "It is useless for you to describe it, because I'll have nothing more to do with you or your inventions. I have given them a fair trial, and they've got me into all sorts of trouble and made all my friends miserable. If I was some high-up scientist it would be different; but I'm just a common boy, and I don't want to be anything else."

"But, your duty – " began the Demon.

"My duty I owe to myself and to my family," interrupted Rob. "I have never cultivated science, more than to fool with some simple electrical experiments, so I owe nothing to either science or the Demon of Electricity, so far as I can see."

"But consider," remonstrated the Demon, rising to his feet and speaking in a pleading voice, "consider the years that must elapse before any one else is likely to strike the Master Key! And, in the meanwhile, consider my helpless position, cut off from all interest in the world while I have such wonderful inventions on my hands for the benefit of mankind. If you have no love for science or for the advancement of civilization, do have some consideration for your fellow-creatures, and for me!"

"If my fellow-creatures would have as much trouble with your electrical inventions as I had, I am doing them a service by depriving them of your devices," said the boy. "As for yourself, I've no fault to find with you, personally. You're a very decent sort of Demon, and I've no doubt you mean well; but there's something wrong about our present combination, I'm sure. It isn't natural."

The Demon made a gesture of despair.

"Why, oh why did not some intelligent person strike the Master Key!" he moaned.

"That's it!" exclaimed Rob. "I believe that's the root of the whole evil."

"What is?" inquired the Demon, stupidly.

"The fact that an intelligent person did not strike the Master Key. You don't seem to understand. Well, I'll explain. You're the Demon of Electricity, aren't you?"

"I am," said the other, drawing himself up proudly.

"Your mission is to obey the commands of whoever is able to strike the Master Key of Electricity."

"That is true."

"I once read in a book that all things are regulated by exact laws of nature. If that is so you probably owe your existence to those laws." The Demon nodded. "Doubtless it was intended that when mankind became intelligent enough and advanced enough to strike the Master Key, you and all your devices would not only be necessary and acceptable to them, but the world would be prepared for their general use. That seems reasonable, doesn't it?"

"Perhaps so. Yes; it seems reasonable," answered the Demon, thoughtfully.

"Accidents are always liable to happen," continued the boy. "By accident the Master Key was struck long before the world of science was ready for it – or for you. Instead of considering it an accident and paying no attention to it you immediately appeared to me – a mere boy – and offered your services."

"I was very anxious to do something," returned the Demon, evasively. "You've no idea how stupid it is for me to live invisible and unknown, while all the time I have in my possession secrets of untold benefit to the world."

"Well, you'll have to keep cool and bide your time," said Rob. "The world wasn't made in a minute, and while civilization is going on at a pretty good pace, we're not up to the Demon of Electricity yet."

"What shall I do!" groaned the Apparition, wringing his hands miserably; "oh, what shall I do!"

"Go home and lie down," replied Rob, sympathetically. "Take it easy and don't get rattled. Nothing was ever created without a use, they say; so your turn will come some day, sure! I'm sorry for you, old fellow, but it's all your own fault."
