"For the chair, yes," replied the spirit. "Still it isn't my chair, and if you want to take the risk, I'm willing. You can kick a football through my ribs if you wish. It's all the same to me."
"I'll try the banger," said Parley, dryly. "Then if you are a sneak-thief, as I half suspect, you'll get what you deserve. If you're what you claim to be, all's well for both of us. Shall I?"
"Go ahead," replied the ghost, nonchalantly.
Parley was more surprised than ever, and was beginning to believe that It was a ghost, after all. No sneak-thief would willingly permit himself to be whacked on the head with any such adamantine weapon as that which Parley held in his hand.
"Never mind," said he, relenting. "I won't."
"Yon must, now," said the other. "If you don't, I can't help you at all. I can't be of service to a person who either can't or won't believe in me. If you want to pass your examinations, whack."
"Bah! What idiocy!" cried Parley. "I—"
"Go ahead and whack," persisted the voice. "As hard as you know how, too, if you want to. Pretend you are cornered by a wild beast, and have only one chance to escape, and whack for dear life. I'm ready. My arms are folded, and I'm sitting right here over the embroidered cushion that serves as the seat of your chair."
"I've caught you, there," said Parley. "You aren't sitting there at all. I can see the embroidered cushion."
"Which simply proves what I say," retorted the ghost. "If I were not a ghost, but a material thing like a sneak-thief, you couldn't see through me. Whack away."
