"Just the same, you were there trying hard, and what's more you endangered your own life in an unfortunate accident while in the act of duty."
And then the superintendent began telling them why he had summoned them to headquarters.
"You chaps doubtless know that the Jules Verne will be ready for her maiden trip within the next two weeks," he began.
The boys perked up at this when it seemed likely they were to be let in on the big secret that had every man in the yard guessing.
"I can only say at this time," continued Mr. Brown, "that the Jules Verne combines our latest improved method of searching the ocean bottom and has facilities that will greatly expedite deep-sea salvage work. You will know in due time, for you chaps will be among the first batch of divers sent out on the Jules Verne. We shall want to thoroughly acquaint you at first with the operation of the new diving bell before you will actually engage in salvage work."
The yard official paused to draw several times on his cigar.
"In the meantime, I need you for a diving expedition of tremendous importance to Uncle Sam. Are you game?"
He looked from one face to the other, eying the boys with a roguish smile.
They nodded their heads eagerly. "If it's for Uncle Sammy, lead us to it!"
