At length Frank jumped from his seat with an exclamation.

“I’ll bet I know where we’re going!” he announced, gleefully.

“So do I!” stated Jimmie in a nonchalant manner.

“Where?” asked Frank, somewhat crestfallen. “Aw, you don’t either!” he declared, after searching his comrade’s face intently.

“All right,” admitted Jimmie, laughing. “I just wanted to take some of that overconfidence out of your system, that’s all!”

“Where do you think we are bound for, Frank?” inquired Ned.

Frank placed a finger on his lips, glancing about to make sure that no one was close enough to overhear his whispered words.

“Helgoland!” he said, cautiously.

Instantly the others jumped to their feet, slapping Frank’s shoulders, shaking his hands and otherwise showing their appreciation of his shrewdness. Their enthusiasm could scarcely be restrained.
