"What for?" asked Dick.
"To show you how he vorks. Den you vill believe. You vill invest some money in it, I shall make der improvements, get a better motor, und ve win der government prize of ten thousand dollars."
"Government prize?" repeated Dick.
The German explained at greater length. The United States Government, in common with other nations, recognizing the future in flying machines for war purposes, had established a sort of competitive test, with a substantial prize for the machine which successfully fulfilled the conditions. The chief ones were that the apparatus must move through the air at a certain distance above the ground, must carry two passengers, must be under perfect control, and must stay up a certain length of time. The German said his machine answered nearly all these requirements, but that he needed some new materials in it, and, more than anything else, a new motor. He had used up all his savings and had tried in vain to get someone to help him. So, hearing of Dick, he had decided to appeal to the millionaire's son.
"It iss not so much dot I need," he went on. "If I had five hundred dollars it would be enough. My dear young frient, I appeal to you. I do not ask you for dot moneys. I say just invest it in my machine und ve vill be successful und get der ten thousand dollars. You shall haf five thousand. Iss not dot a good investment?"
A sudden idea came to Dick. An investment, promising quick returns was just what he needed. He had tried in vain to find one, and the time was daily growing shorter. Here might be the very chance he desired. But there was one important thing. He must be sure that the airship would fly. If it did not the prize would not be won and he would be out five hundred dollars. Herr Doodlebrod saw the doubt pictured on Dick's face.
"I do not ask you to take my word," he said, gravely. "I only ask for a chance to show you. See, I vill bring my machine here. I vill put him togeder und I vill fly in him. Der trouble iss dot I cannot go far enough or stay up long enough vid der motor dot I haf. Wid a new vun I can. I need der money for der new motor. Vill you invest it?"
"I will!" exclaimed Dick, suddenly.
"Ach! Bless you, my young friend!" and Herr Doodlebrod rushed over to the millionaire's son and threw his arms about Dick, an embrace somewhat difficult to escape from, so hearty was it.
"But I must first talk to my father," went on Dick, when Herr Doodlebrod's enthusiasm had somewhat cooled down. "If the ship is a success so far, and by investing five hundred dollars a better one can be entered for the prize, so that I can win part of it, I'm sure he would have no objections."
