Shadow, I got you that time."

"Well, it's a good story anyway," answered Shadow, ruefully.

"I shan't attempt to stop Nat unless he makes some direct accusation,"

said Dave, calmly. "What would be the use? It would only make matters worse."

"If you took notice of what he says, some folks would begin to think there was something in it," said Phil. "Yes, better drop Nat. He isn't worth bothering about, anyway. Just the same, it is mean for him to speak in this fashion."

"He wouldn't be Nat Poole if he didn't," retorted Roger.

Despite this incident, the boys and girls managed to have a good time on the ice, and for an hour or two Dave forgot his troubles and those of his friends.

"What are you going to do for the rest of the vacation, Dave?" said Roger, that evening. "You know you promised to come to my home."

"Yes, and you promised to visit me, too," added Phil. "You haven't been to our house in a long time."

"To tell the truth, I haven't the heart to go anywhere," answered Dave, soberly. "I guess I had better stay here and see if something doesn't turn up."

"Well, I can't blame you," said the senator's son, and Phil said the same.

CHAPTER XIV-OFF FOR THE SOUTH

Two days later, when Roger was packing up, getting ready to return home, he received a letter from Luke Watson that filled him with interest.

Luke had gone to St. Augustine, Florida, to join his folks, who were spending the winter there.

"Here's news!" burst out the senator's son, as he came rushing to Dave and Phil with the epistle. "This letter is from Luke Watson, you know his folks are in Florida. Well, on his way to St. Augustine, Luke stopped for a day at Jacksonville. Listen to what he says:

"'I was walking down one of the main streets of Jacksonville, looking into the shop windows, when what do you think? I saw Link Merwell and Nick Jasniff. You could have knocked me over with a feather, for I hadn't imagined that they were anywhere near. They were nattily dressed and each carried a small valise, and they were buying caps and some other things for a sea voyage. I went into the shop and called to them, and my! both of them jumped as if they were shot, and Merwell got so pale I thought he was going to faint. I said "h.e.l.lo," but they didn't answer to that, and Jasniff at once wanted to know if I was alone. When I told him I was he seemed mightily relieved, and Merwell looked relieved, too. They wanted to know what I was doing there and I told them. Then I asked what they were doing, but I couldn't get any straight answer. Merwell started to say something about going to sea, but Jasniff stopped him short, and said they guessed they would go back to New York, where they had come from.

"'It was awful funny-they positively looked scared to death, and while they were talking to me they looked over my shoulders, as if on their guard against somebody. I asked them what they had been doing since they left Rockville, and they said not much of anything, just traveling around. They seemed to have plenty of money, for just as I went into the shop I saw Merwell pay for something from a big roll of greenbacks.

"'After I left them, I got a bit curious about the pair, and so I watched them come from the shop and walk down to one of the docks and go aboard a big four-masted schooner. I hung around a little and pretty soon they came from the schooner and went up to one of the big hotels, and there I lost sight of them. Each had his little valise with him, but they weren't big enough for much clothing. My, but they were scared! I fancy they thought I might pitch into them for the mean things they did in the past. But I didn't want to start any row.'"

"Is that all he says?" demanded Dave, after the senator's son had finished.

"That's all he says about Merwell and Jasniff and their doings."

"Doesn't he mention the name of that schooner, or the hotel?" asked Phil.

"No."

"Did you say Luke was going to Jacksonville?" asked our hero.

"Yes, his whole family are down there."

"Then I could telegraph to him and he could give me the name of the hotel, and of the schooner."

"Dave, what do you make out of this?" demanded the senator's son.

"I make out of it that Merwell and Jasniff are guilty!" burst out Dave.

"They went from here to Florida, and now they have either gone to sea, or are going, as soon as that schooner sails. Do you notice what Luke says about their being scared almost to death when they saw him? They evidently thought some of us, or the officers of the law, were with him."

"And the little valises!" burst out the shipowner's son. "Perhaps they contain the jewels!"

"Would they be foolish enough to carry them around like that?"

questioned Roger. "Wouldn't they hide them?"

"They may be looking for some good hiding-place, or some place where they can sell them," answered Dave. "Remember, Jasniff and Merwell are green at this business-they wouldn't go at it like professionals. If they were professionals, they wouldn't have acted so scared."

"That is true. What will you do, tell Mr. Wadsworth of this?"

"I think I'll tell my father and my Uncle Dunston first. Mr. Wadsworth doesn't place much credit in the story of Merwell and Jasniff's guilt.

He thinks the detectives are on the right track."

"Well, possibly they are," admitted Phil. "But I must say, this looks mighty suspicious to me."

"I have half a mind to take matters in my own hands and run down to Jacksonville," went on our hero. "Who knows but what I might find Merwell and Jasniff? If I did, I could stop them and make them give an account of themselves by making that old charge of abduction against them, and that charge of having used my name."

"Say, that's an idea!" cried Roger. "And say, I'd like to go with you."

"So would I," added Phil. "We might go down in one of my father's ships."

"Too slow, Phil-the limited express for this trip," answered Dave. "But I must talk it over with dad first," he added.

"We have got over three weeks before school opens again," pursued the senator's son. "We could go down to Florida and back easily in that time."

Dave's father had gone to New York on business, but came home that evening. In the meantime a telegram was sent to Luke Watson, asking for the name of the hotel, at which Merwell and Jasniff had stopped, and of the schooner.

Dave's father and his uncle listened closely to what he had to tell, and to the reading of the letter from Luke Watson. They talked the affair over for an hour with the boys.

"You may be right, boys," said Mr. Porter, at last. "And it may be a good plan to follow those rascals up. But I don't think I would bother Mr. Wadsworth about it. He received a telegram from one of the detectives, and the officer is more sure than ever that he is on the right track. He caught Red Andrews p.a.w.ning a fair-sized diamond, and he thinks the gem is from the Carwith collection."

"Can't he make Red Andrews confess?" asked Dave.

"Unfortunately the rascal got away when on the way to the police-station. But the detective feels he can soon round him up again."

Dave looked thoughtfully out of the window and tapped the table with his fingers.

"You still think Merwell and Jasniff guilty?" remarked his uncle, with a smile.

"Yes, Uncle Dunston. After what Hooker Montgomery said, I'll think them guilty until somebody proves otherwise."

"Then I tell you what I'll do, boys," said Dunston Porter. "I'll take a trip down to Florida with you and look into this matter. I'd rather be on the move than sitting still waiting for something to turn up."

"Will you go?" cried Dave, eagerly.
