ht entered at the sliding-door above, and to this his
eyes were naturally drawn.

Here was another puzzle. He explored his memory, and could recall no
such place as this. He had never before been in such a room.

At last he recalled the circumstances under which he fell asleep, and he
jumped to the conclusion that he was in the same house still.

"They must have put me to bed," he said to himself. "They were very
kind; but this is a queer room."

Thus far no thought that he was a prisoner had entered his mind.

He arose and began to feel his way around by the walls. He judged that
he was in a room not more than ten feet square. He could form no idea
what was the time. It might be the middle of the night, so far as he
knew.

"This is awkward," he thought. "I don't fancy being shut up like this.
Where's the door? There must be one somewhere."

He found it at last, and tried the lock, but it did not yield to his
efforts.

Then came the startling thought:

"Am I a prisoner?"

He stopped short and thought over the situation. He recalled all he
could of the men in whose company he had been at the time he went to
sleep. The longer he thought the more it seemed probable that it was as
he suspected.

Though a little startled at this view of the situation, Jasper was by no
means disposed to be despondent. His courage arose with the difficulties
of his position.

"I'll find out how matters stand," he said to himself. "I'll pound till
somebody comes."

He began to pound on the walls of the room with such effect that the old
man below heard him.

"The bird is beating against the walls of his cage," he thought. "I'll
go up and see him."

Presently Jasper heard steps ascending the stairs. Almost immediately
another sliding-door about four feet from the floor was drawn open, and
the old man's face was poked in.

"Did you knock?" he asked, grinning.

"Yes," said Jasper. "Open the door, and let me out."

"Won't you have some supper first?" asked Nathan, with a leer.

"No; I'd rather go out," said Jasper, in a tone of suspicion.

"I couldn't allow that. Oh, no!" said Nathan.

"What right have you to keep me here against my will?" exclaimed Jasper,
furiously.

"We like your company so much, my dear young man," said Nathan, nodding
his head waggishly.

"Who's 'we'?" demanded Jasper.

"Jack, and Bill, and me."

"Let me out, I say."

"Don't be agitated, my dear boy. You'll be taken good care of."

"I'd ra
