"A chaser!" cried Torry, finding his voice and growing excited.

"She's aiming right this way," added Frenchy excitedly.

Phil Morgan had his glass out again, and his lips unpuckered and the
tune he had been monotoning died.

"What do you make of her, Phil?" whispered Al Torrance.

"It is a sub patrol boat all right," agreed their leader.

Ikey, who had the tiller at this juncture, got so excited watching the
swiftly approaching craft that he pretty nearly swung the _Sue Bridger_
in a circle.

"Look out, you chump!" yelled Torry. "Want to yank the stick out of her?
If you haven't a care Captain Bridger will get the price of a new
catboat out of us."

Whistler gave Torrance the glass and went aft himself to relieve Ikey at
the helm.

"You're a fine garby," called Donahue to Rosenmeyer. "Lose your head
mighty easy. That chaser isn't chasing us."

"How do you know she isn't?" returned Ikey.

"She certainly is following us," Whistler said. "But until she bespeaks
our attention with her forward gun I guess we need not worry," and he
smiled grimly.
