So instead of galloping off post haste to the freight station, the boys proceeded to get their car in shape to bring back the parts of the airship. They left in the automobile only a few needful things, took along plenty of ropes and some food, for they expected to be away all day, since it might require some little searching to find a sufficiently secluded spot.

“We want to pick out some place in the woods where the cowboys don’t come,” suggested Jerry. “If one of them happened to spy the craft before we had her together it would spoil the surprise and we’d lose all the effect we want to produce.”

His chums agreed with him, and after a little judicious inquiry made of the foreman they got on the track of a place that they thought would just suit their purposes. It was in a clump of rather wild wood on the edge of a sandy plain. As the sand prevented the grass from growing, it was avoided by the cattle. In consequence of this there was no need for the presence of the cowboys in that vicinity.

“And it will be just the place for us,” Jerry said. “The sandy plain will be an ideal starting ground for the beginning of our flight. There’s no water near there and we’ll have to cart enough in the auto for the airship radiator, but we can easily do that. And now we’ll start.”

“Got ’em in there?” asked Hinkee Dee in his sneering voice as he saw the boys start for the railroad station in their big car.

“Got who in where?” Bob questioned before he thought.

“The cattle thieves!” chuckled the assistant foreman. “I s’pose you’ve got ’em hog-tied and all ready for the sheriff.”

“Not yet,” admitted Jerry, trying to be good-natured about it. “But we’re on their trail.”

“Oh, yes!” went on Hinkee Dee. “All you’re waiting for is a post card from ’em, givin’ their address so’s you can call for ’em. I’ve heard of such detective work before!” and with a jingle of his spurs he rode away at a fast pace, he and his pony being soon lost to sight in a cloud of dust.
