"I am here!" he announced.
"So am I," answered Rob. "But at one time I really thought I should never see you again. I've been—"
"Spare me your history," said the Demon, coldly. "I am aware of your adventures."
"Oh, you are!" said Rob, amazed. "Then you know—"
"I know all about your foolish experiences," interrupted the Demon, "for I have been with you constantly, although I remained invisible."
"Then you know what a jolly time I've had," returned the boy. "But why do you call them foolish experiences?"
"Because they were, abominably foolish!" retorted the Demon, bitterly. "I entrusted to you gifts of rare scientific interest—electrical devices of such utility that their general adoption by mankind would create a new era in earth life. I hoped your use of these devices would convey such hints to electrical engineers that they would quickly comprehend their mechanism and be able to reproduce them in sufficient quantities to supply the world. And how do you treat these marvelous gifts? Why, you carry them to a cannibal island, where even your crude civilization has not yet penetrated!"
"I wanted to astonish the natives," said Rob, grinning.
