No more did Stubby allow the red monoplane to creep up into a challenging position. He was sure of his plane now. The yellow ship was not to be outdone. It streaked away a good half lap in the lead when the checkered flag brought the close of the contest.

Stubby silently received the congratulations accorded the winner. The motor had proved to stand the test. The plane had come through and defeated all Brent’s enemies. Brent would probably sell his plans to the government. His plane had won—but where was Brent?

Chapter X
WHAT HAPPENED

Quebec was a fascinating city to Gale. The old churches and streets, the people, friendly and smiling, all charmed her. She walked beside Brent, feeling as happy as she had ever felt in her life. It had been such a marvelous trip up to Quebec, and they had made it in such a marvelously short time. They were to have a late supper with Mr. Howard before they were to start back to Marchton, late the same night.

Gale regretted leaving this intriguing city so soon after her arrival, but tomorrow’s air races would be thrilling, too. She mentioned this to Brent and saw his eyes gleam in anticipation at the thought of his plane a possible winner.

The two young people stopped in a little shop for postcards and souvenirs and lingered too long. When they emerged onto the street again and Brent disclosed his wrist watch they were amazed at the time. Immediately they hurried to the little restaurant where they were to meet Gale’s father.

There they found he could not go back to Marchton with them that night. He had already made arrangements to stay at a hotel until the next day for a further talk with the man he had come to see.

“May I stay too?” Gale asked eagerly.

But her father refused, as she had expected him to do. She was to fly back with Brent as had been planned. Mr. Howard accompanied them to the plane.

Gale had asked Brent to circle over the city and fly over a little more of Canada before setting his course southward. Now as the plane streaked over the ground and rose into the blackness of the clouds Gale watched with interest the scene below her. Lights flickered on and off. She noticed the stars overhead had disappeared. The moon was hidden behind clouds and the air was much colder. Gale huddled down in the cockpit and was thankful for her woolly coat, but she could have stood even more.
