you could build anything speedier than your Butterfly, son?"
"I think so, father. That is, if you'd help me. I have a plan partly thought out, but it will take some time to finish it. Still, I might get it done in time."
"I hope you'll try!" exclaimed the secretary. "May I ask whether it would be a monoplane or a biplane?"
"A monoplane, I think," answered Tom. "They are much more speedy than the double-deckers, and if I'm going to try for the ten thousand dollars I need the fastest machine I can build."
"We have the promise of one or two very fast monoplanes for the meet," went on Mr. Gunmore. "Would yours be of a new type?"
"I think it would," was the reply of the young inventor. "In fact, I am thinking of making a smaller monoplane than any that have yet been constructed, and yet one that will carry two persons. The hardest work will be to make the engine light enough and still have it sufficiently powerful to make over a hundred miles an hour, if necessary.
