Publisher's Synopsis
"Father," exclaimed Tom Swift, looking up from a paper he was reading, "I think I can win that prize!""What prize is that?" inquired the aged inventor, gazing away from a drawing of a complicated machine, and pausing in his task of making some intricate calculations. "You don't mean to say, Tom, that you're going to have a try for a government prize for a submarine, after all.""No, not a submarine prize, dad," and the youth laughed. "Though our Advance would take the prize away from almost any other under-water boat, I imagine. No, it's another prize I'm thinking about."
