"Well," remarked Tom, when he had gone out to look at his Humming- Bird, "I know one thing.Andy Foger may build a machine something like this, but I don't believe he can put in all the improvements I have, and certainly he can't equal that engine; eh, dad?""I hope not, Tom," replied his father, who seemed to be much improved in health.
"When are you going to try for speed?" asked Mr.Damon.
"To-morrow, if I can get it tuned up enough," replied Tom, "and I think I can.Yes, we'll have the great test to- morrow, and then I'll know whether I really have a chance for that ten thousand dollars."Never before had Tom been so exacting in his requirements of his air craft as when, the next day, the Humming-Bird was wheeled out to the flight ground, and gotten ready for the test.The young inventor went over every bolt, brace, stay, guy wire and upright.He examined every square inch of the wings, the tips, planes and rudders.The levers, the steering wheel, the automatic equilibrium attachments and the balancing weights were looked at again and again.
As for the engine, had it been a delicate watch, Tom could not have scrutinized each valve, wheel, cam and spur gear more carefully.Then the gasoline tank was filled, the magneto was looked after, the oil reservoirs were cleaned out and freshly filled, and finally the lad remarked:
"Well, I guess I'm ready.Come along, Mr.Damon." "Am I going with you in the test?""Surely.I've been counting on you.If you're to be with me in the race, you want to get a sample of what we can do.Take your place.Mr.Jackson, are you ready to time us?""All ready, Tom."
"And, dad, do you feel well enough to check back Mr.Jackson'sresults? I don't want any errors." "Oh, yes, Tom.I can do it.""Very well, then.Now this is my plan.I'm going to mount upward on an easy slant, and put her through a few stunts first, to warm up, and see that everything is all right.Then, when I give the signal, by dropping this small white ball, that means I'm ready for you to start to time me.Then I'll begin to try for the record.I'll go about the course in a big ellipse, and-- well, we'll see what happens."While Mr.Damon was in his seat the young inventor started the propeller, and noted the thrust developed.It was satisfactory, as measured on the scale, and then Tom took his place.
"Let her go!" he cried to Mr.Jackson and Eradicate, after he had listened to the song of the motor for a moment.The Humming-Bird flew across the course, and a moment later mounted into the air.
Tom quickly took her up to about two thousand feet, and there, finding the conditions to his liking, he began a few evolutions designed to severely test the craft's stability, and to learn whether the engine was working properly.
"How about it?" asked Mr.Damon anxiously.
"All right!" shouted Tom in his ear, for the motor was making a great racket."I guess we'll make the trial next time we come around.Get ready to drop the signal ball."Tom slowly brought the aeroplane around in a graceful curve.He sighted down, and saw the first tall white pole that marked the beginning of the course.
"Drop!" he called to Mr.Damon.
The white rubber ball went to the earth like a shot.Mr.Jackson and Mr.Swift saw it, and started their timing- watches.Tom opened the throttle and advanced the spark.The great test was on!
The Humming-Bird trembled and throbbed with the awful speed of the motor, like a thing alive.She seemed to rush forward as an eagle dropping down from a dizzy height upon some hapless prey.
"Faster yet!" murmured Tom."We must go faster yet!"The motor was warming up.Streaks of fire came from it.The exhaustof the explosions was a continuous roar.Faster and faster flew the frail craft.
Around and around the air course she circled.The wind appeared to be rushing beneath the planes and rudders with the velocity of a hurricane.Had it not been for the face protectors they wore, Tom and Mr.Damon could not have breathed.For ten minutes this fearful speed was kept up.Then Tom, knowing he had run the motor to the limit, slowed it down.Next he shut it off completely, and prepared to volplane back to earth.The silence after the terrific racket was almost startling.For a moment neither of the aviators spoke.Then Mr.Damon said:
"Do you think you did it, Tom?"
"I don't know.We'll soon find out.They'll have the record." And he motioned toward the earth, which they were rapidly nearing.
