"I don't see that there is anything I can do. I'll go on to the meet, of course, and trust to some improvements I have since brought out, and to what I know about aeroplanes, to help me win the race. I'll know, too, who stole my plans."
"But it will be too late, then."
"Yes, too late, perhaps, to stop them from using the drawings, but not too late to punish them for the theft. It's a great mystery, and I'll be on the anxious seat all the while. But it can't be helped."
"When are you going to start work on the sky racer?"
"Pretty soon, now. I've got another set of plans made, and I've fixed them so that if they are stolen it won't do any one any good."
"How's that?"
"I've put in a whole lot of wrong figures and measurements, and scores of lines and curves that mean nothing. I have marked the right figures and lines by a secret mark, and when I work on them I'll use only the proper ones. But any one else wouldn't know this. Oh, I'll fool 'em this time!"
"I hope you do. Well, when you get the machine done I'd like to ride in it. Will it carry two, as your Butterfly does?"
"Yes, only it will be much different; and, of course, it will go much faster. I'll give you a ride, all right, Ned. Well, now I must get busy and see what material I need for what I hope will prove to be the speediest aeroplane in the world."
"That's going some! I must be leaving now. Don't forget your promise. I saw Mary Nestor on my way over here. She was asking for you. She said you must be very busy, for she hadn't seen you in some time."
