“I’ll answer for thot,” Jameson promised him. “I made thorough soundings.”

“Let’s start right off, then. Every instant counts. Dancer, will you go below to the wheel?”

“How long will it take us to run down the coast to the barracks, Jameson?” asked Mr. Chadwick.

“Not more than an hour. How fast can ye go?”

He was told.

“Then ye’ll do it in less time than that in the bonnie bit divin’ boat.”

The engines were started at once, and at top speed they set off for the barracks where the regular troops were quartered.

“I wish we had a dozen marines off the old Ohio,” grumbled old Silas as they sped along, “they’d lick all the rebels that ever breathed.”

“What, all of them, Silas?” asked Tom, winking at Jack.
