The Master Key Part 3

"If this goes on," Mr Joslyn said to his son, when breakfast was finished, "I shall be obliged to send you away for your health."

"I think of making a trip this morning," said Rob, carelessly.

"Where to?"

"Oh, I may go to Boston, or take a run over to Cuba or Jamaica,"

replied the boy.

"But you can not go so far by yourself," declared his father; "and there is no one to go with you, just now. Nor can I spare the money at present for so expensive a trip."

"Oh, it won't cost anything," replied Rob, with a smile.

Mr. Joslyn looked upon him gravely and sighed. Mrs. Joslyn bent over her son with tears in her eyes and said:

"This electrical nonsense has affected your mind, dear. You must promise me to keep away from that horrid workshop for a time."

"I won't enter it for a week," he answered. "But you needn't worry about me. I haven't been experimenting with electricity all this time for nothing, I can tell you. As for my health, I'm as well and strong as any boy need be, and there's nothing wrong with my head, either.

Common folks always think great men are crazy, but Edison and Tesla and I don't pay any attention to that. We've got our discoveries to look after. Now, as I said, I'm going for a little trip in the interests of science. I may be back to-night, or I may be gone several days.

Anyhow, I'll be back in a week, and you mustn't worry about me a single minute."

"How are you going?" inquired his father, in the gentle, soothing tone persons use in addressing maniacs.

"Through the air," said Rob.

His father groaned.

"Where's your balloon?" inquired sister Mabel, sarcastically.

"I don't need a balloon," returned the boy. "That's a clumsy way of traveling, at best. I shall go by electric propulsion."

"Good gracious!" cried Mr. Joslyn, and the mother murmured: "My poor boy! my poor boy!"

"As you are my nearest relatives," continued Rob, not noticing these exclamations, "I will allow you to come into the back yard and see me start. You will then understand something of my electrical powers."

They followed him at once, although with unbelieving faces, and on the way Rob clasped the little machine to his left wrist, so that his coat sleeve nearly hid it.

When they reached the lawn at the back of the house Rob kissed them all good-by, much to his sisters' amus.e.m.e.nt, and turned the indicator of the little instrument to the word "up."

Immediately he began to rise into the air.

"Don't worry about me!" he called down to them. "Good-by!"

Mrs. Joslyn, with a scream of terror, hid her face in her hands.

"He'll break his neck!" cried the astounded father, tipping back his head to look after his departing son.

"Come back! Come back!" shouted the girls to the soaring adventurer.

"I will--some day!" was the far-away answer.

Having risen high enough to pa.s.s over the tallest tree or steeple, Rob put the indicator to the east of the compa.s.s-dial and at once began moving rapidly in that direction.

The sensation was delightful. He rode as gently as a feather floats, without any exertion at all on his own part; yet he moved so swiftly that he easily distanced a railway train that was speeding in the same direction.

"This is great!" reflected the youth. "Here I am, traveling in fine style, without a penny to pay any one! And I've enough food to last me a month in my coat pocket. This electricity is the proper stuff, after all! And the Demon's a trump, and no mistake. Whee-ee! How small everything looks down below there. The people are bugs, and the houses are soap-boxes, and the trees are like clumps of gra.s.s. I seem to be pa.s.sing over a town. Guess I'll drop down a bit, and take in the sights."

He pointed the indicator to the word "down," and at once began dropping through the air. He experienced the sensation one feels while descending in an elevator. When he reached a point just above the town he put the indicator to the zero mark and remained stationary, while he examined the place. But there was nothing to interest him, particularly; so after a brief survey he once more ascended and continued his journey toward the east.

At about two o'clock in the afternoon he reached the city of Boston, and alighting un.o.bserved in a quiet street he walked around for several hours enjoying the sights and wondering what people would think of him if they but knew his remarkable powers. But as he looked just like any other boy no one noticed him in any way.

It was nearly evening, and Rob had wandered down by the wharves to look at the shipping, when his attention was called to an ugly looking bull dog, which ran toward him and began barking ferociously.

"Get out!" said the boy, carelessly, and made a kick at the brute.

The dog uttered a fierce growl and sprang upon him with bared teeth and flashing red eyes. Instantly Rob drew the electric tube from his pocket, pointed it at the dog and pressed the b.u.t.ton. Almost at the same moment the dog gave a yelp, rolled over once or twice and lay still.

"I guess that'll settle him," laughed the boy; but just then he heard an angry shout, and looking around saw a policeman running toward him.

"Kill me dog, will ye--eh?" yelled the officer; "well, I'll just run ye in for that same, an' ye'll spend the night in the lockup!" And on he came, with drawn club in one hand and a big revolver in the other.

"You'll have to catch me first," said Rob, still laughing, and to the amazement of the policeman he began rising straight into the air.

"Come down here! Come down, or I'll shoot!" shouted the fellow, flourishing his revolver.

Rob was afraid he would; so, to avoid accidents, he pointed the tube at him and pressed the b.u.t.ton. The red-whiskered policeman keeled over quite gracefully and fell across the body of the dog, while Rob continued to mount upward until he was out of sight of those in the streets.

"That was a narrow escape," he thought, breathing more freely. "I hated to paralyze that policeman, but he might have sent a bullet after me. Anyhow, he'll be all right again in an hour, so I needn't worry."

It was beginning to grow dark, and he wondered what he should do next.

Had he possessed any money he would have descended to the town and taken a bed at a hotel, but he had left home without a single penny.

Fortunately the nights were warm at this season, so he determined to travel all night, that he might reach by morning some place he had never before visited.

Cuba had always interested him, and he judged it ought to lie in a southeasterly direction from Boston. So he set the indicator to that point and began gliding swiftly toward the southeast.

He now remembered that it was twenty-four hours since he had eaten the first electrical tablet. As he rode through the air he consumed another. All hunger at once left him, while he felt the same invigorating sensations as before.

After a time the moon came out, and Rob amused himself gazing at the countless stars in the sky and wondering if the Demon was right when he said the world was the most important of all the planets.

But presently he grew sleepy, and before he realized what was happening he had fallen into a sound and peaceful slumber, while the indicator still pointed to the southeast and he continued to move rapidly through the cool night air.

5. The Cannibal Island

Doubtless the adventures of the day had tired Rob, for he slept throughout the night as comfortably as if he had been within his own room, lying upon his own bed. When, at last, he opened his eyes and gazed sleepily about him, he found himself over a great body of water, moving along with considerable speed.
