to get ahead of me and take advantage, they would do it. But they would not sneak in to steal my ideas. I feel sure of that. Besides, they have a certain type of submarine which they think is the best ever invented, and they would hardly change at this late day. They feel sure of winning the Government prize, and I'm just as glad we're not going to have a contest."
"Do you think our boat is better than theirs?"
"Much better, in many respects."
"I don't like that man Berg, though," went on Tom.
"Nor do I," added his father. "There is something strange about him. He was very anxious that I should compete. Probably he thought his firm's boat would go so far ahead of ours that they would get an extra bonus. But I'm glad he didn't see our new method of propulsion. That is the principal improvement in the Advance over other types of submarines. Well, another week and we will be ready for the test."
"Have you known Mr. Berg long, dad?"
"Not very. I met him in Washington when I was in the patent office. He was taking out papers on a submarine for his firm at the same time I got mine for the Advance. It is rather curious that he should come all the way here from Philadelphia, merely to see if I was going to compete.
