"As to that," returned the Demon, composedly, "I am not. But I have hopes that with the addition of the three marvelous devices I shall present you with to-day you will succeed in arousing so much popular interest in electrical inventions as to render me wholly satisfied with the result of this experiment."
Rob regarded the brilliant apparition with a solemn face, but made no answer.
"No living person," continued the Demon, "has ever before been favored with such comforting devices for the preservation and extension of human life as yourself. You seem quite unappreciative, it is true; but since our connection I have come to realize that you are but an ordinary boy, with many boyish limitations; so I do not condemn your foolish actions too harshly."
"That is kind of you," said Rob.
"To prove my friendliness," pursued the Demon, "I have brought, as the first of to-day's offerings this Electro-Magnetic Restorer. You see it is shaped like a thin metal band, and is to be worn upon the brow, clasping at the back of the head. Its virtues surpass those of either the fabulous 'Fountain of Youth,' or the 'Elixir of Life,' so vainly sought for in past ages. For its wearer will instantly become free from any bodily disease or pain and will enjoy perfect health and vigor. In truth, so great are its powers that even the dead may be restored to life, provided the blood has not yet chilled. In presenting you with this appliance, I feel I am bestowing upon you the greatest blessing and most longed-for boon ever bequeathed of suffering humanity."
