"I don't think so. Of course he had on a slouch hat, drawn down over his eyes, and an unusual suit of clothing, but I am pretty certain it was Merwell."

"Then Haskers must be here, too. They travel together." Dave heaved a sigh. "It's too bad! I wish they were in China, or at the North Pole!"

It was two days after Dave's arrival at Crumville and most of the time had been spent in getting ready for the trip to Montana. Roger and Phil were coming to the house that afternoon, and Dave had received a telegram from Shadow Hamilton that he would accompany the tourists as far as Yellowstone Park. The other lads were unable to make the necessary arrangements.

It was lunch time and Dave lost no time in going to Mr. Wadsworth, who had just come in from his jewelry works. Both of them, accompanied by Dave's father, went into the library to talk the matter over, so that Jessie and her mother might not be disturbed.

"I'll see the police about this," said Mr. Wadsworth, when he had heard about Merwell. "If possible, we must place this young scamp where that fellow Jasniff is, behind the bars."

"I wish they could arrest Haskers, too," sighed Dave.

"I don't see how we can—we have no charge against him," answered the manufacturer.

It was about three o'clock when Roger and Phil came in. As my old readers know, the senator's son and Dave's sister were on unusually good terms with each other, and the greeting between them was very cordial.

"But I don't like you for one thing, Roger," said Laura, half reproachfully. "I don't like this idea of Dave going off to look for that lost mine."

"Oh, we won't be away from you long, Laura."
