"How long a job is this?" he demanded so suddenly that the words were out before he knew he was going to ask the question.

"How long? Well—that's hard to say. Until you fail to put me across the line safely, I suppose. There's always something doing or going to be done in Mexico, old man—and it's always worth reporting to the Syndicate. How long will people go on reading their morning paper at breakfast?" He smiled the tolerant, bored smile that Johnny associated with his first sight of Cliff. "I should say the job will last as long as you make good."

"Well, that puts it up to me, then. I'd want an agreement that I'd be paid a week in advance all the time. That's to cover the risk of costly breakage and things like that. At the end of every week I'd be free to quit or go on, and you'd be free to let me out if I didn't suit. With that understanding I'll try her out—for a week, starting to-morrow morning." He added, by way of clinching the matter, "And that goes."

Cliff Lowell blew a thin wreath of smoke and smiled again. "It goes, far as I am concerned. I think the old man will agree to it, providing you take oath you'll keep the whole thing secret. I haven't preached that to you, but the whole scheme blows up the minute it is made public. You understand that, of course, and I'm not afraid of you; but the old man may want some assurance. If he does, you can give it, and if he does not, it will be because he is taking my word that you are all right.

"Now let's get down to business. How long will it take you to get the machine in shape? And can't you make arrangements with the owner of this field to leave it here for the present—and perhaps get him to keep an eye on it? Wait. You leave him to me. I think he's a Jap, and I know Japs pretty well. I'll go hunt him up and talk to him. If we can run it under cover for a couple of days, all the better."

He climbed into his car and went off down the road to where the roofs of several buildings showed just above a ridge. His talk must have been well lubricated with something substantial in the way of legal tender, for presently he returned, and behind him a team came down the road hauling a flat hayrack on which four Japs sat and dangled their legs to the jolting of the wagon.

"He's a good scout, and he will keep the plane under cover for us," Cliff announced in a satisfied tone. "They're going to load it on the wagon and haul it home, where there's a shed I think will hold it. If it won't, we'll buy it and knock out an end or something."

The four Japs, chinning unintelligibly and smiling a good deal, loaded the Thunder Bird to Johnny's satisfaction, hauled it to the buildings over the ridge, and after they had knocked all the boards off one side to admit the wings, ran it under a shed. Afterwards they nailed all the boards on again while Johnny stood around and watched them uneasily, secretly depressed because his Thunder Bird was being penned in by gibbering brown men who might be unwilling to return it to him on demand.

For good or ill, he was committed now to Cliff Lowell's project. Even though he was committed for only a week, qualms of doubt assailed him at intervals during their roaring progress to the city. Cliff drove with an effortless skill which filled Johnny with envy. Some day—well, a car like this wouldn't be so bad. And if the job held out long enough— Why, good golly, think of it! And Mary V thought he couldn't make any money with his airplane. Wanted him to go to work for her dad—think of that!

Thinking of it; he tried to silence the qualms. Tried to reassure himself with Cliff's very evident sincerity, his easy assurance that all would be well. Johnny had been canny enough to make the agreement by the week—surely nothing much could go wrong in that little while, and if he didn't like the look of things after a week's try-out, he could quit, and that would be all there would be of it. It was too good a chance to let slip by without a trial, anyway. A man would be a fool to do that; and Johnny, whatever he thought of himself, did not consider himself a fool.
