Johnny looked back from the gate and heaved a great sigh of relief at his narrow escape.  Or was it regret?  Johnny himself did not know, but he called it relief because that was the most comfortable emotion a young man may take away with him into desert loneliness.

Yes, sir, he was glad of the chance to stay at Sinkhole for awhile.  He wouldn’t be pestered to death, and he would have plenty of time to study and read.  He’d send for that correspondence course on aviation, and he’d get the theory of it all down pat, so that when he had enough money saved up to go into the thing right, all he would need would be the actual practice in the air.  He should think he could go to some school and work his way along; get a little practice every day, and do repair work or something the rest of the time for nothing.  A dollar a minute for learning was pretty steep, Johnny thought, but after all it was worth it.  A dollar a minute—­and four hundred minutes in the air for the average course!

Four hundred dollars, and only half that much saved.  And then there would be his fare back east, and his board—­Johnny wished that he might cut out eating, but he realized how healthy was his appetite.  He counted three meals for every day, at an average of fifty cents for each meal.  Well, even so, he could “ride the bumpers” to the school; take a side-door pullman; beat his way; hobo it—­or whatever the initiated wanted to call it.  He could send his suitcase on by express, and just wear old clothes—­send his money on, too, for that matter.  He could save quite a lot that way.  Or maybe he could get Sudden to let him go back with cattle from the Gila River Ranch—­only he wouldn’t ask any favors from any one by the name of Selmer.  No, he’d be darned if he would!  He’d just draw his wages, when he had enough saved, and drop out of sight.  He wouldn’t even tell Curley where he was going.  And then, some day—­

There came the air castle again, floating alluringly before his eager imagination, like a mirage lake in the desert.  Johnny’s eyes stared ahead through the shimmering heat waves—­stared and saw not the monotonous neutral tints of sand and rock and gray sage and yellow weeds and the rutted, dusty trail that wound away across the desert.  But Mary V’s face turned expectantly toward him from the crowd as he walked nonchalantly around his big tractor, testing every cable, inspecting the landing gear and the elevators and the—­what-ye-may-call-’ems—­and then climbing in and trying out his control—­and pulling down his goggles and settling his moleskin cap and all—­and then nodding imperiously to his helper—­not little Curley; he was not big enough to crank his powerful motor—­but some big guy that had a reach like—­

And then the buzz and the hum, and fellows braced against the wings to hold ’er till he was ready to give the word!  And the dust storm he kicked up behind—­he hoped Mary V got her eyes full, darn her!—­and then, getting the feel of ’er, and giving a nod to the fellows to let go the wings!  And then—­
