“How do you mean?” asked the tall lad, “turn a somersault, or something like that?”
“No, but speed around, do some stunts and then come down in the middle of the park.”
And indeed Jerry was not a little proud of what their craft could do, so he was willing to fall in with Bob’s idea.
The _Comet_ was sent up, and then directed downward. Then Jerry put her through some intricate evolutions, to show what control he had of her.
Though it was early there was a big crowd on the grounds and they were much interested in what was going on. The boys could see thousands of persons gazing up at them. They noted numbers of tents and sheds which evidently housed the big aircraft. There were several balloons without shelter, the big bags, partly filled, swaying in the wind.
One dirigible in particular attracted their attention. It was very large, and seemed to have a large boat-shaped cabin attached below it. In fact, the lower part was not unlike their own _Comet_.
About this craft there was quite a throng, and men could be seen busily engaged, evidently in getting it ready for a flight.
“Well, I guess we’ve done enough,” remarked Jerry at length. “We’d better go down.”
“Yes,” agreed Ned. “I’d like to see what sort of a craft that one is,” and he motioned to the big dirigible.
Hardly had he spoken than there came a shout from below, and the balloon rose swiftly in the air.
“They’re making an early flight!” cried Bob. “We missed ’em.”
“Oh, we can see from here just as well,” said Jerry, as he checked the downward progress of the _Comet_ for a moment.
Upward shot the big dirigible, amid the cheers of the onlookers, and then, wishing to make as good a landing as possible, and needing good speed and control to effect this, Jerry again sent the motor-ship downward.
A little later the motor boys landed in the midst of a big, green, open space, while the crowd thronged up around them, cheering their impromptu exhibition, and asking all sorts of questions.
“Here at last!” cried Ned, with a sigh of relief. “Now to find Mr. Jackson.”
Overhead the big dirigible was shooting forward through space, for her propellers had been set in motion. The boys watched her with great interest, little knowing how their own fate was interwoven in that of the strange craft.
