"This gyroscope idea is all your own, you have worked it out well in model. To put it into a practical, working-sized plane will take money. In fact you will need a great deal of money--which you haven't got. To a degree, I am a man of wealth. But at present, my factories need a stirring advertising campaign, something to turn the eyes of the world towards us. The Bojer Works, and others that turn out planes inferior to ours, are by their daring advertisements deflecting part of our natural business to themselves." The Colonel's hands crumpled some papers in a tense grasp. He paused a moment, as though to get a grip on himself, then went on. "For our plant to build the plane that wins the great Onheim Prize--ah, that would be unexcelled advertising for us! We will put up the money and the factory experience to build your model into its completed practical form. You will fly it and win the prize. Your model must win--it's the biggest idea born in the last twenty years! The Onheim twenty-five thousand dollars will be yours! The right to build planes after your model will be ours, but with a per cent of the profits coming to you. Do you agree?"
