“What’s the matter? Afraid he’ll take your girl?” asked Tom, with a laugh. But Sid did not reply.

Nothing more had been discovered about the missing jewelry, nor had Tom and his chums been able to follow the clues which they had stumbled upon. The torn handkerchief, the empty jewelry box, the shreds of silk, had been put away, together with Boswell’s card. Mendez, the Mexican, had been seen around Haddonfield several times since Tom and Ruth had met him on the island, and he seemed to be selling his wares, there being little need of his remaining on the island as caretaker all day. Whenever he met Tom, he was very polite, but our hero cared no more for the swarthy man than he had at first.

“He’s altogether too nice,” decided our hero, though he realized this was nothing against the man. Certainly there seemed to be nothing to point suspicion to him, any more than to Boswell, and the four chums did not dare make an untoward move. It was too risky, Frank said.

As for the Boxer Hall lads, though some might have held a faint thought that their Randall rivals were responsible for the loss of the cup trophies, no one said so in that many words. Still many Randallites felt that a grim suspicion hung over the college, caused by the unfortunate fact that Tom and his chums had been first on the ground when the articles were discovered to be gone from the wrecked boat.

“Hang it all!” exclaimed Tom, as he and his chums were about to separate for the vacation, to meet soon again, “I wish we could get on the trail of that stuff, and the man who took it!”

“So do I!” added Frank. “Well, maybe something will turn up this Summer.”

As for Ruth, she had successfully kept her secret with Tom. If her girl friends noticed the absence of her old brooch they said nothing.

Mr. Farson, the jeweler, fretted much over his loss, but it did no good. He even increased the reward, to no more purpose. It all remained a mystery. He did not even know as much as the boys did about the affair, and, for their own reasons, the students kept silent.

Our four heroes dispersed to their homes, to meet warm welcomes there. Then came preparations for going camping on Crest Island. The Tyler cottage was opened by some of the servants and put in shape for Summer occupancy. Madge wrote to Ruth, Mabel and Helen, bidding them get ready to come when she sent word.

Tom spent a week or two at the shore, “recuperating,” as he put it, from the hard study incidental to the examinations.
