"Not exactly fun," said John, seriously; "but I will admit this voyage is rather exciting."

Just then something snapped, and they heard a rapid whir of machinery inside the bird, a squeak that sounded like a wail of despair, and then a dull crash. The big machine trembled, ceased flopping its wings, and remained poised in the air like an immense kite.

"It's all up," said Chick. "The thing's busted."

"What's going to happen?" asked John, anxiously.

"Wait and see," returned Chick, with a laugh.

"It's cruel to laugh when we are in such grave danger!" said John, reproachfully.

"Shucks!" cried the child. "It might be my last laugh, and I'd be foolish to miss it."

The bird was still floating, for its broad wings were rigidly spread out to their fullest extent; but every moment the machine sailed nearer to the sea, and although it was surely nearing the island, neither John nor Chick could decide whether it would finally succeed in reaching the shore or fall into the water.

Even the careless Cherub paused with bated breath to watch the final catastrophe, and John, resigned to whatever fate might befall him, nevertheless passed the most anxious moments of his brief lifetime.
