Rob examined the garment with much curiosity.  It glittered like silver, yet was soft and pliable as lamb's wool.  Evidently the Demon had prepared it especially for his use, for it was just Rob's size.
"Now," continued the Demon, more gravely, "we approach the subject of an electrical device so truly marvelous that even I am awed when I contemplate the accuracy and perfection of the natural laws which guide it and permit it to exercise its functions.  Mankind has as yet conceived nothing like it, for it requires full knowledge of electrical power to understand even its possibilities."
The Being paused, and drew from an inner pocket something resembling a flat metal box.  In size it was about four inches by six, and nearly an inch in thickness.
"What is it?" asked Rob, wonderingly.
"It is an automatic Record of Events," answered the Demon.
"I don't understand," said Rob, with hesitation.
"I will explain to you its use," returned the Demon, "although the electrical forces which operate it and the vibratory currents which are the true records must remain unknown to you until your brain has mastered the higher knowledge of electricity.  At present the practical side of this invention will be more interesting to you than a review of its scientific construction.
"Suppose you wish to know the principal events that are occurring in Germany at the present moment.  You first turn this little wheel at the side until the word 'Germany' appears in the slot at the small end.  Then open the top cover, which is hinged, and those passing events in which you are interested will appear before your eyes."
