"You are right," responded Mumps. "Hurry up; I don't want to be arrested."

As quickly as it could be done they carried Dora aboard of the yacht and bundled her into the cabin.

"Now keep her there!" cried Baxter to Mrs. Goss. "After we are off you can explain how she got away."

"She hit me with a stick and knocked me down," said the woman glibly. "She shan't get away a second time."

Once again poor Dora found herself a prisoner on board of the Flyaway. Then the lines were cast off, the sails set, and they stood off in the darkness, down New York Bay and straight for the ocean beyond.

CHAPTER XX

A LONG CHASE BEGUN

As they journeyed down the Hudson the boys and Martin Harris scanned the river eagerly for some sign of the Flyaway.

"It's ten to one she put down a pretty good distance," remarked Dick. "They wouldn't bring Dora over here unless they were bound for New York or some other place as far or further."

"I believe you," said Tom. "But she may be delayed, and if what Harris says is true the Searchlight ought to make better time than Baxter's craft."
