e was uppermost, and he was afraid to go and look. But
he had to look. He had to know, for he was still boy enough to feel
solemnly bound by the toss. He walked slowly toward it, stared hard--and
pounced like a kid after a hard-won marble.

"Heads, I go! That's the way I flipped 'er; it's a fair throw."

At the sound of his voice ringing in the confined space, Sandy lifted his
head and looked at Johnny tolerantly. Johnny came toward him grinning,
tossing the half-dollar and catching it, his steps springy. The last few
yards he took in a run, and vaulted into the saddle without touching the
stirrups at all. Even that did not seem to ease him quite. So he gave a
whoop that echoed and re-echoed from the rock walls and made Sandy squat,
lay back his ears, and shake his head violently.

At the mouth of the hidden nook Johnny turned to take a last, gloating
survey of the place in the deepening dusk. "She sure will make one bird
of a hangar!" he told Sandy glowingly. "Golly! Oh, good _golly_!"

CHAPTER SEVEN

FINDER, KEEPER

From the crest of a low, sandy ridge that had on it a giant cactus
standing with four spiney, knobbed fingers uplifted like a warning hand,
Johnny surveyed with wide, red-rimmed eyes the hidden basin that held his
heart's desire. Tomaso's brother sat his sweaty horse beside Johnny and

"Unh-hunh," Johnny conceded absent-mindedly. He was trying to make the
thing look real to him after all the visions he had had of it.

He had had his spells of doubting the probity of Tomaso's brother; of
secretly wondering whether the story of the plane might not be a ruse to
lure him away from Sinkhole. But then, how would Tomaso or his brother
know that Johnny would care anything about whether an airplane "sat" over
in Mexico within riding distance of the Border? Johnny did not think of
Tex as a possible factor in the proposition.

Well, there it was, anyway, not a quarter of a mile away. Between him and
the object of his quest the sand lay wrinkled in tiny drifts, with here
and there a ragged gray bush leaning forlornly from the wind. One wing of
the machine was tilted, as though it had careened a little in the winds,
but from that distance Johnny could not tell what damage had been do
