“It sounds easy enough,” assented Harry.

“Yes, unless you happen to get caught!” agreed Ned.

“What is there to catch us?” asked Jimmie, bristling at this hint of opposition. “The guards are all wise to the fact that the channel is mined. They will be sleepy and lazy. They know that the torpedoes are not aboard yet and believe it impossible for the submarine to leave without a crew. The weather looks as if it were going to be rough. What more can you want?

“So did I!” added Jack. “I couldn’t guess what it was, though!”

“It was my arm!” declared Jimmie, with mock gravity. “Now, let’s go back to this ‘Untervasserbootschiff’ and stall around a while.”
