“Let her go!” cried Bob. “I’ve got everything ready for a meal above the clouds.”

“Oh, of course,” murmured Ned. “No danger of you forgetting anything in that line.”

Professor Snodgrass was busy mending a hole in his butterfly net. Jerry was in the pilot house, while Ned and Bob were in the engine room.

“All ready?” inquired the tall lad.

“All ready,” replied Ned, with a final look at the machinery.

“Then here we go!”

“Good-bye!” called the little lad. “Good luck! Off you go! Up in the air! Whizz around! Turn over—right side up with care—off again—high as Gilroy’s kite—win the prize—whoop-ee!”

“Well, I’m glad that’s over,” murmured Jerry with a smile.
