Mr. Delavan turned quickly, though not with such a start as did his friend, Moddridge.

Astern, or, rather, over the port quarter, appeared a long, narrow racing hull. It was evidently the same motor craft that had so nearly rammed them in the deep fog.

“Confound that hoodoo boat,” muttered Mr. Delavan, in a low tone, to his companion. “I’d give quite a bit to know who are aboard that craft.”

“S-s-so would I,” stammered Moddridge. “It looks queer. Whoever they are, they’re dogging us, of course.”

“That’s what I’d like to know,” returned Delavan, musingly.

“Shall I keep to the same course, sir?” asked Captain Tom, as soon as his employer looked around.

“Why, now, I’ll tell you what I want you to do, captain,” answered the owner. “Run out towards the ‘Kaiser,’ though you needn’t be at pains to make it too plain that you’re seeking the big ship. After you get the ‘Rocket’ somewhat near, take a wide, sweeping turn to landward of the big craft. Run fairly near, keeping your port hull about parallel with the ‘Kaiser’s’ starboard. Run alongside for a little distance, until your orders are changed. Moddridge and I are going down into the cabin, to take our stations at port-holes. Prentiss will stand by the cabin doorway to pass up, in a low voice, any orders that I may give him for you. Is that all clear, captain?”

“Quite clear, sir.”

“Then come below, Moddridge,” continued the owner, turning to his friend. “And for goodness’ sake, man, if you can, behave differently. Don’t let your legs shake so under you.”

“I c-c-can’t help it,” stammered the smaller man, nervously.
