But Frank said nothing. If he believed that he would have an easy thing of it, and leave his rival far in the lurch, he gave no expression to such views.

"Here come the judges," remarked Elephant; "and they're going to explain just what the conditions of the race will be. Yes, Percy has quit laughing. He looks sober enough right now. Listen to what Judge Perrine says, fellows."

The judge had gained a spot between the rival biplanes, where he could be easily heard. Then he started to explain just what the committee having the race in charge had decided the rules should be.

In the first place, he remarked, it would be utterly suicidal for the young aviators to think of trying for height on such a threatening day. That would be left until the second afternoon, to be settled then, if both parties were agreed.

After that he went on to state how points were to be given for expert management of the aeroplane, as seen from the start and return; also for speed. The time of reaching the liberty pole at Hazenhurst was to be taken there by a member of the committee sent over for that purpose. After leaving that town the rival biplanes were to circle the peak of Old Thunder Top three times, and last of all make a landing on the campus.

"Any questions, either of you, before the word is given to start?" asked the gentleman in charge of arrangements, after he had finished reading his rules.

Neither of the contestants evidently had anything to ask. They knew what they had to do only too well; and both were like restive horses, awaiting the tap of the bell, or the crack of the pistol, to be off on the jump.

That vast crowd surged and swayed, everybody wishing to see the start, which would prove a novel sight to many of the country people at least. Once the aeroplanes had soared aloft, their flight could be watched without trouble.

Frank and Andy had mounted to their places; and an air of expectancy hung over the broad campus. After they had left the earth it would be a straightaway course for both contestants in the direction of Hazenhurst.

"Are you ready?" asked the starter, in loud voice.
