But he did not dare leave camp for more than half an hour or so at a time, because he never knew what minute Cliff might return and want him; and when one is being paid something like ten dollars an hour, waking or sleeping, for his time, one feels constrained to keep that precious time absolutely available to his employer. At least, Johnny felt constrained to do so. He could not even go duck hunting. Mateo hunted the ducks, using Johnny's gun or Cliff's, and seldom failing to bring back game. It would be ducks shot by Mateo which would furnish the circumstantial evidence which Cliff mentioned that morning.

Johnny went out to the Thunder Bird, shooed three kids from under the wings, and began to fuss with the motor. One advantage of being idle most of the time was the easy life the Thunder Bird was leading. The motor was not being worn out on this job, at any rate.

So far he had not spent a hundred dollars of his salary on the upkeep of his machine. He was glad of that, because he already had enough to pay old Sudden and have the price of a car left over. With the Thunder Bird clear, and a couple of thousand dollars to the good—why, he would not change places with the owner of the Rolling R himself! He could go back any time and vindicate himself to the whole outfit. He could pick Mary V up and carry her off now, without feeling that he was taking any risk with her future. Poor little girl, she would be wondering what had become of him; he'd write, or send a wire, if Cliff would ever open his heart enough to take a fellow with him to where there was a post-office or something.

He was beginning to feel a deep need of some word from Mary V, was Johnny. He was beginning to worry, to grow restive down here in the wilderness, seeing nothing, doing nothing save kill time between those short, surreptitious flights across to the notched ridge and back again. Two weeks of that was beginning to pall.

But the money he was receiving did not pall. It held him in leash, silenced the doubts that troubled him now and then, kept him temporizing with that uneasy thing we call conscience.

He climbed now into the cockpit, testing the controls absent-mindedly while he pondered certain small incidents that caused him a certain vague discomfort whenever he thought of them. For one thing, why must a gatherer of news carry mysterious packages into Mexico and leave them there, sometimes throwing them overboard with a tiny parachute arrangement, as Cliff had done on the first trip, and flying back without stopping? Why must a newspaper man bring back certain mysterious packages, and straightway disappear with them in the car? That he should confer long and secretly with men of florid complexions and an accent which hardens its g's and sharpens its s's, might very plausibly be a part of his gathering of legitimate news of international import. Though Johnny rather doubted its legitimacy, he had no doubt whatever of its world-wide importance. Certain nations were at war—and he was no fool, once he stopped dreaming long enough to think logically.

Those packages bothered him more than the florid gentlemen, however. At first he suspected smuggling, or something like that. But gun-running, that staple form of border lawbreaking, did not fit into any part of Cliff's activities, though opium might. But when he had made an excuse for handling one or two of the packages, they routed the opium theory. They were flat and loosely solid, as packages of paper would be. Not state documents such as melodramas use to keep the villains sweating—they did not come in reams, so far as Johnny knew. He could think of no other papers that would need smuggling into or out of a country as free as ours where freedom of the press has become a watchword; yet the idea persisted stubbornly that those were packages of paper which he had managed to take in his hands.

As a pleasing relief from useless cogitation on the subject, Johnny took his bank roll from a pocket he had sewed inside his shirt. Like a miser he fingered the magic paper, counting and recounting, spending it over and over in anticipatory daydreams. Thirty-two hundred dollars he counted in bills of large denomination—impressively clean, crisp bills, some of them—and mentally placed that amount to one side. That would pay old Sudden, interest and all. What was left he could do with as he pleased. He counted it again. There were three hundred dollars left from what Bland had earned—Bland— What had become of Bland, anyway? Little runt might be broke again; in fact, it was practically certain that he would be broke again, though he must have had close to a hundred dollars when they landed in Los Angeles. Oh, well—forget Bland!

So there were the three hundred—gee golly, but it had cost, that short stay in the burg of Bland's dreams. A hundred dollars gone like the puff of a cigarette! Well, there were the three hundred left—he'd have been broke, pronto, if he had stayed there much longer. Another hundred he had spent on the Thunder Bird—golly, but propellers do cost a lot! And that shotgun he never had had a chance to shoot—Cliff sure was a queer guy, making him buy all that scenery, and then caching him away so no one ever got a chance to size him up and see whether he looked like a duck hunter or not. Well, anyway, let's see. There were a thousand in big juicy hundreds; and five hundred more in fifties and twenties—

Out beyond the oak's leafy screen the dogs were barking and growling and the children were calling shrilly. Johnny hastily put away his wealth and eased himself up so that he could peer out through the branches. He had not consciously feared the coming of strangers, yet now he felt his heart thumping noisily because of the clamor out in the yard. While he looked, two horsemen rode past and stopped at the cabin.
