"The Dictionary button. I press the Dictionary button, and the Dictionary tells me whatever I want to know. Just listen to this."
The Imp pressed a button as he spoke, and Jimmieboy listened. In an instant there was a loud buzzing sound, and then an invisible something began to speak, or rather to sing:
"She's my Annie,
I'm her Joe.
Little Annie Rooney—"
"Dear me!" cried the Imp, his face flushing to a deep crimson. "Dear me, I got the wrong button. That's my Music-room button. It's right next the Dictionary button, and my finger must have slipped. I'll just turn 'Annie Rooney' off and try again. Now listen."
Again the Imp touched a button, and Jimmieboy once more heard the buzzing sound, followed by a squeaking voice, which said:
"Battery is a noun—plural, batteries. In baseball the pitcher and catcher is the battery; in electricity a battery is a number of Leyden jars, usually arranged with their inner coatings connected, and their outer coatings also connected, so that they may be all charged and discharged at the same time."
"Understand that, Jimmieboy?" queried the Imp, with a smile, turning the Dictionary button off.
"No, I don't," said Jimmieboy. "But I suppose it is all right."
"Perhaps you'd like an explanation of the explanation?" suggested the Imp.
"If it's one I can understand, I would," returned Jimmieboy. "But I don't see the use of explanations that don't explain."
