2. The Demon of Electricity

Rob was a courageous boy, but a thrill of fear passed over him in spite of his bravest endeavor as he gazed upon the wondrous apparition that confronted him. For several moments he sat as if turned to stone, so motionless was he; but his eyes were nevertheless fastened upon the Being and devouring every detail of his appearance.

And how strange an appearance he presented!

His jacket was a wavering mass of white light, edged with braid of red flames that shot little tongues in all directions. The buttons blazed in golden fire. His trousers had a bluish, incandescent color, with glowing stripes of crimson braid. His vest was gorgeous with all the colors of the rainbow blended into a flashing, resplendent mass. In feature he was most majestic, and his eyes held the soft but penetrating brilliance of electric lights.

It was hard to meet the gaze of those searching eyes, but Rob did it, and at once the splendid apparition bowed and said in a low, clear voice:

"I am here."

"I know that," answered the boy, trembling, "but WHY are you here?"

"Because you have touched the Master Key of Electricity, and I must obey the laws of nature that compel me to respond to your summons."

"I--I didn't know I touched the Master Key," faltered the boy.

"I understand that. You did it unconsciously. No one in the world has ever done it before, for Nature has hitherto kept the secret safe locked within her bosom."

Rob took time to wonder at this statement.

"Then who are you?" he inquired, at length.

"The Demon of Electricity," was the solemn answer.

"Good gracious!" exclaimed Rob, "a demon!"

"Certainly. I am, in truth, the Slave of the Master Key, and am forced to obey the commands of any one who is wise and brave enough--or, as in your own case, fortunate and fool-hardy enough--to touch it."

"I--I've never guessed there was such a thing as a Master Key, or--or a Demon of Electricity, and--and I'm awfully sorry I--I called you up!" stammered the boy, abashed by the imposing appearance of his companion.

The Demon actually smiled at this speech,--a smile that was almost reassuring.

"I am not sorry," he said, in kindlier tone, "for it is not much pleasure waiting century after century for some one to command my services. I have often thought my existence uncalled for, since you Earth people are so stupid and ignorant that you seem unlikely ever to master the secret of electrical power."

"Oh, we have some great masters among us!" cried Rob, rather nettled at this statement. "Now, there's Edison--"

"Edison!" exclaimed the Demon, with a faint sneer; "what does he know?"

"Lots of
