And, catching up a folded tripod, the crazy man stood guard, so that Bob might not escape from the studio.

CHAPTER XIV
BOB MAKES A NEW MOVE

Bob was alarmed when the crazy man strode forward, tripod in hand, as if to brain him should he attempt to leave the studio.

He had not had much to do with people of unsound mind, but he was well aware that his present position was both a delicate and a dangerous one.

If the lunatic attacked him, he would have a hard struggle to keep himself from harm, for, despite his hollow eyes and shrunken form, the man looked strong.

“I’m not going to leave,” said Bob. “Put down the tripod, and sit in the chair if you want the picture of your skeleton taken.”

He left the vicinity of the door, and seeing this the crazy man at once dropped the folded tripod and sank into a chair.

“Will you take the picture?” he demanded.

“I will if you will promise to go away right afterward,” returned the youth.

“That goes. Take me this way, and be quick. I must catch the next ocean steamer for the Sandwich Islands.”
