But Chick tugged at his puffy brown hand and hurried him on, for the Incubator Baby at that very moment thought of a clever way to save the gingerbread man. Still holding John's hand, the child ran through the upper passages to the foot of the tower of Imar, and began climbing up the steep stairs as fast as possible. Luckily for the fugitives, these stairs to the tower were very difficult for Ali Dubh to climb by hopping. When he was half-way up he lost his balance and tumbled down again, and this accident gave John and Chick time to enter the body of the bird flying-machine, which still lay stretched upon the roof of the tower.
"Quick!" shouted the child, shutting and fastening the silver door behind them. "Pull over that lever, and away we go!"
"Is it safe?" asked John, hesitating.
"Is it safe to be eaten?" inquired Chick.
John quickly grabbed the lever, pulled it over, and the huge bird fluttered its wings once or twice and rose slowly into the air. It sailed away from the roof just as the Arab appeared at the top of the stairs.
"Stop!" screamed Ali Dubh. "You're mine, John Dough. Come back and be eaten."
"Don't mind him," said the Cherub, peeping at the Arab through a little window in the bottom of the bird's body. "And don't worry about this flying-machine, either. Imar has told me how to run it, and it will carry us somewhere, never fear. This button that I pushed is to start it, and there's another button somewhere to stop it."
"Where?" asked John.
