"I wanted to astonish the natives," said Rob, grinning.
The Demon uttered an exclamation of anger, and stamped his foot so fiercely that thousands of electric sparks filled the air, to disappear quickly with a hissing, crinkling sound.
"You might have astonished those ignorant natives as easily by showing them an ordinary electric light," he cried, mockingly.  "The power of your gifts would have startled the most advanced electricians of the world.  Why did you waste them upon barbarians?"
"Really," faltered Rob, who was frightened and awed by the Demon's vehement anger, "I never intended to visit a cannibal island.  I meant to go to Cuba."
"Cuba!  Is that a center of advanced scientific thought?  Why did you not take your marvels to New York or Chicago; or, if you wished to cross the ocean, to Paris or Vienna?"
"I never thought of those places," acknowledged Rob, meekly.
"Then you were foolish, as I said," declared the Demon, in a calmer tone.  "Can you not realize that it is better to be considered great by the intelligent thinkers of the earth, than to be taken for a god by stupid cannibals?"
