“Fat chance of getting this old hurdy-gurdy fixed up in time to make it,” grumbled Jimsy.

“You don’t have to,” cried Peggy, with a note of triumph.

“Don’t have to!”

It was Jess who echoed the remark.

“No, indeed. Our aerial express will start for the junction in a few minutes, and––”

But the rest was drowned in an enthusiastic shout. Jess threw her arms about her chum and fairly hugged her.

“You darling. We can make it?”

“We must,” was the business-like rejoinder. “Roy, you get the Butterfly out and fill the lubricator tank. We’ve got enough gasolene.”

Roy and Jimsy, arm in arm, hastened off to the shed. The two girls followed more leisurely. It was not long before everything was in readiness, but fast as they worked it was nearly half an hour before preparations were all complete.

Then they climbed in and Peggy started the engine. But the next instant she shut it off again.
