Jack.

"No, sah," said Washington. "Dat's de only fault I kin fin' with dat name—it don't 'pear to stop him. An' befo' I kin git it all out he's ginerally out ob sight!"

That sent both boys off into another paroxysm of laughter. Meanwhile the darkey had come into the great shed and was slowly walking around the flying machine. "What do you think of her, Wash, now that she's finished?" asked Mark.

"Is she done done?" queried the darkey, wonderingly.

"She certainly is," agreed Jack.

"De chile is bawn and done named Nebbercudsneezer, heh? Well! well!"

"No; it's named the Snowbird," Mark retorted. "And to-morrow morning, bright and early, we shall sail on its trial trip. The professor is going with us, Washington. Of course, you will come, too?"

"Lawsy me! don't see how I kin!" stammered Washington White, who always wished to be considered very brave, but who was really as timid as a hare. "Yo' see, Massa Mark, I'spect I shall be right busy."

"What will you be busy at?" demanded Jack.

"Well—well, sah," said Wash, "if dat Shanghai don't come back befo', I shall hab ter go snoopin' aroun' de kentry a-huntin' fo' him. He'll be crowin' 'bout sun-up, an' he suah can't disguise his crow."
