“I’ll do what I can,” Jack told him quietly, “and pay doesn’t enter into it. We’re not sure which way he went.”

“Even if he did say he was going to Luxlow, I’d guess he headed for Bryson,” Madge interposed. “If he reached there by afternoon he could get a train out for New York. His Luxlow connections would be very poor.”

“He was askin’ me about the Elf Lake portage only yesterday,” Bill volunteered.

“But if he did go the other way, we’ll lose him,” Anne said anxiously, as the ranger moved toward his canoe.

“I’m striking for Elf Lake,” Jack said crisply. “Mr. Brownell, you go to Luxlow and try to head Clyde off there. Bill can drive you in.”

The plan was instantly adopted. Jack sprang into his canoe but Madge was directly behind.

“Let me go too! You can make faster time with two paddling.”

Jack hesitated briefly, then nodded. Madge slid into the bow and caught up a paddle. Anne gave the canoe a shove, wading far out into the water.

“Oh, I hope you catch him!” she shouted. “Paddle for all you’re worth!”

Jack and Madge cut directly across the lake, taking a course straight as a die. Madge realized that to overtake the chemist they must travel at double his speed. She had a muscular arm and made each stroke count. Several times the ranger warned her to take it easier.
