"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 every 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."
