"Take a look at our engine!" Dave growled. "It was no nightmare, son. Say, Freddy. You won't laugh, will you?"

"Lord knows I could do with a good laugh right now," the English youth said and unbuckled his uncomfortable parachute harness. "But what's on your mind? I promise not to laugh."

"Those guys who came popping out on that sub's deck like rabbits," Dave said after a long frowning pause. "Know what they looked like to me?"

"What?"

"Like Japs," Dave said, straight faced.

Freddy Farmer gulped and blinked. It was a couple of seconds before he could get his tongue to form the word.

"Japs?" he gasped.

"Sure, Japs," Dave repeated. "You know, short for Japanese. I'll bet you that was a Jap submarine, and those guys who let fly at us were Japs."

The English youth pondered over that a moment, and meanwhile kept up his nervous-eyed search of the surrounding rolling swells.

"They did have the Japanese build, I'll admit," he finally said. "But.... Lord! It's fantastic, Dave! Why in the world would a Jap submarine come to the surface and blast away at us? We're not even carrying a torpedo, to say nothing of bombs."
