"Especially as I haven't it fully patented," went on the young inventor. He had met with many failures in his efforts to perfect this motor, which he intended to install on one of his airships. "If any one saw the finished parts now it wouldn't take them long to find out the secret of doing away with the noise."
"How do you do it?" asked Ned, for he realized that his chum had no secrets from him.
"Well, it's too complicated to describe," said Tom, "but the secret lies in a new way of feeding gasoline into the motor, a new sparking device, and an improved muffler. I think I could start my new airship in front of the most skittish horse, and he wouldn't stir, for the racket wouldn't wake a baby. It's going to be great."
"What are you going to do with it, when you get it all completed?"
"I haven't made up my mind yet. It's going to be some time before I get it all put together, and installed, and in that time something may turn up. Well, let's talk about something more pleasant than Andy Foger. I guess I won't worry about him."
"No, I wouldn't. I'd like to see the motor run."
"You can, in a day or so, but just now I need a certain part to attach to the sparker, and I had to send to town for it. Koku has gone after it."
