"That's true, Harry; but if no spirits have been seen, neither has anyone else to whom you could attribute the extraordinary doings we want to account for."

"I shall discover them."

"Ah, Harry! Harry! it's not so easy to catch the spirits of New Aberfoyle!"

"I shall find out the spirits as you call them," said Harry, in a tone of firm conviction.

"Do you expect to be able to punish them?"

"Both punish and reward. Remember, if one hand shut us up in that passage, another hand delivered us! I shall not soon forget that."

"But, Harry, how can we be sure that these two hands do not belong to the same body?"

"What can put such a notion in your head, Jack?" asked Harry.

"Well, I don't know. Creatures that live in these holes, Harry, don't you see? they can't be made like us, eh?"

"But they ARE just like us, Jack."

"Oh, no! don't say that, Harry! Perhaps some madman managed to get in for a time."

"A madman! No madman would have formed such connected plans, or done such continued mischief as befell us after the breaking of the ladders."
