"We can't go much further tonight, anyway," said Harris. "I don't know but what it may be as well to tie up somewhere."

"We'll have to do that unless we can catch some sort of clue," responded Dick gloomily. "If they have taken her to some place in New York we'll have a big job to find her."

A half-hour passed, and they were on the point of turning in at a dock when Tom gave a cry. "Look! Look!"

"What's up, Tom!" came from Dick and Sam simultaneously.

"Is that the Flyaway?"

All gave a look and saw a large yacht moving away from a dock just below where they had thought to stop.

"Call Harris!" cried Dick, and Sam ran to the cabin for the sailor, who had just gone below.

"I reckon that's our boat," said Martin Harris, after a quick look.

"Hark!" cried Dick, and held up his hand. "That's Dan Baxter's voice, just as sure as fate."

"I believe you," returned Sam. "Come, we can run her down in no time."
