"Who knows?" said Chick. "Imar was always afraid to go very far from the island with it. We'll just have to wait and find out."

This was not very encouraging, but it was too late to return now, the Isle of Phreex being lost in the vastness of the great sea. Moreover, John reflected that he would be in greater danger there from Ali Dubh than in riding in an untried flying-machine. The only thing to do was to continue the flight through the air until they sighted some other land—provided the machine did not suddenly break down. It seemed to be all right just at present, and John's admiration of Imar's genius in constructing it grew steadily as the bird flopped on and on without a sign of giving out.

Chick wasn't frightened, that was certain. The Baby laughed and sang little songs, and seemed as happy and contented as when upon firm land; so John gradually forgot his fears. The sun had sank low upon the horizon, and was looking for a good place to dive into the sea, when the voyagers discovered something far ahead of them that glittered brightly upon the water. Neither could determine what the glitter meant, until they drew nearer and saw a small, rocky islet, upon which was perched an enormous palace that seemed to be made of pure gold, having many crystal windows set in its domes and sides.

"It is certainly a beautiful place," said John. "Let us land upon the islet."

"All right," returned Chick. "I'll see if I can find out which button stops the thing."

The Baby pushed one of the buttons, and at once the bird shot up higher into the air.

"That isn't it!" cried John, in sudden alarm.

Chick pushed another button, and the machine began whirling around in short circles.
