"Why, we know very well it ain't the name of it," yelled Cap'n Bill from below. "We jus' called it that 'cause its right name is too hard to say."

"That's the whole trouble, then," returned Button-Bright. "Somewhere in the world there's a real Sky Island, and having told the Magic Umbrella to take us there, it's going to do so."

"Well, I declare!" gasped the sailorman. "Can't we land anywhere else?"

"Not unless you care to tumble off," said the boy. "I've told the umbrella to take us to Sky Island, so that's the exact place we're bound for. I'm sorry. It was your fault for giving me the wrong name."

They glided along in silence for a while. The island was now far behind them, growing small in the distance. "Where do you s'pose the real Sky Island can be?" asked Trot presently.

"We can't tell anything about it until we get there," Button-Bright answered. "Seems to me I've heard of the Isle of Skye, but that's over in Great Britain, somewhere the other side of the world, and it isn't Sky Island, anyhow."

"This miser'ble ol' umbrel is too pertic'ler," growled Cap'n Bill. "It won't let you change your mind an' it goes ezzac'ly where you say."

"If it didn't," said Trot, "we'd never know where we were going."

"We don't know now," said the sailor. "One thing's certain, folks: we're gett'n' a long way from home."

"And see how the clouds are rolling just above us," remarked the boy, who was almost as uneasy as Cap'n Bill.
