“Watch,” said Jerry, and he steered the machine up an incline on the main highway that led out of Cresville.

“She’s doing it!” commented Bob, who was in a rear seat.

“I take my hat off to you, Jerry,” admitted Ned, as the crest of the hill was reached. “You certainly know how to work her.”

“It’s all in the motor,” said the tall lad. “Having her gone over, and the valves reground, was just what she needed.”

“Well, we’ll need all the power we can crowd into her before we get to the end of this trip,” declared Bob. “We’ve never made such a long journey in this big car before.”

“That’s right,” assented Jerry. “But she’ll do it. And say, maybe we won’t have good times when we get out to the ranch! Your father says there are big level stretches of country there, Ned, just the place for starting and landing our airship.”

“Fine!” cried Ned. “We’ll whoop things up when we get out among the cowboys.”

“They may whoop things up for us,” commented Jerry.

“What do you mean?” asked Bob.

“Oh, nothing, only you know they may class us as tenderfeet, and start to put a few tricks over on us.”
