“I think we’re high enough up now!” observed Frank, presently.
He no longer sent the biplane in widening circles, boring steadily
upwards; but turned toward the south and pushed for speed, as far as
was compatible with safety, which was always Frank’s way.
And Andy seemed to have now lost all interest in what lay behind,
for he was looking ahead through the glasses, as though in the hope
of discovering the kidnapper of little Becky somewhere in the hazy
distance.
It was still comparatively early in the morning, and in places there
lay an odd sort of mist that may have been a mirage, obscuring the
view, since the earth was hidden in its whitish folds.
Away beyond these spots did Andy turn his marine glasses. Now he saw
something moving that at first gave him a little shock; but on
second inspection it turned out to be a sailing buzzard, evidently
scenting some carrion in a bunch of sage brush, that gave promise of
dinner, since it was close to the earth at the time.
A minute later and Andy had another start, as once more he believed
he had discovered an object that certainly crawled over the ground.
Could it be some wounded man, or one who was perishing for a drink
of water, in that arid land bordering the desert?
But hardly had this thought occurred to Andy than he realized his
mistake; for he now saw that it was only a cowardly coyote,
shuffling along as though ashamed to be caught returning to his den
at such an hour of the morning, after an all night feast, perhaps.
Down below them they could see the plain which formed a part of
Double X Ranch. It looked like a great checkerboard, on account of
the different colors of the soil, which stood out in relief when one
was directly above. Had there been any water there they could have
seen to the very bottom, even though it were twenty feet deep, such
is the advantage which this lofty position gives. No wonder, thought
Andy, that the hawk is able to pick out just the fish he wants for
his dinner, and then finds it so easy to pounce down upon the
unfortunate thus selected.
Frank was listening to the buzz of the motor. Whenever they were
thus humming along through space this was his favorite occupation.
And indeed, when one stops to consider how much depended on the
successful operation of that same industrious engine, he could be
easily excused for taking such intense interest in its labors. Let
it suddenly get out of condition and it would bring the daring young
aviators face to face with a crisis that might threaten even their
lives. Deprived of the means of making progress would necessitate a
volplane toward the ground, always a dangerous performance and one
that should only be attempted when the conditions are all favorable,
or some desperate need arises.
Turn whichever way Andy would nothing but disappointment seemed to
meet him; and being pretty much an impulsive boy, perhaps it was
only natural that he should voice his disgust.
“Oh! I wouldn’t give that any worry,” Frank told him. “If Jose has
had as much time as we think, he must be away ahead of the line of
your observation just now, especially on account of all that haze
along the horizon.”
“But if we can’t see him, how are we to know that we’re keeping in a
direct line after him?” demanded the one who wielded the glasses.
“We can only take our chances,” Frank answered, steadily, as though
he did not mean to be ruffled so early in the game, when so many
things remained untried, any one of which might sooner or later
prove to be the magic key, fated to unlock the treasure chest.
“And just keep on heading south, is that it, Frank?”
“Exactly so, Andy. We’re about dead sure that it’s Jose who carried
away Little Sunbeam; and knowing that, we can figure he’s sure to
make a bee line for the nearest place where the border comes. So I’m
shaping our course for that same region myself. And when we get
there, perhaps we’ll find we’ve been left in the lurch and that his
fast ponies have won the day.”
“And what then, Frank; would we have to turn around and come back
like a dog with his tail between his legs, just because the
kidnapper managed to quit American soil, and get on that belonging
to Mexico? As for me, I’d be willing to give him the merry chase
right down along the line till we landed in Mexico City, or else in
a Black Hole in some town on the way.”
“I feel pretty much the same way, Andy; but first of all, you see,
we’ve just got to find out where the man and child are. So keep on
looking while I drive her along a little faster. I think we can
stand another turn, with this light and favorable breeze carrying us
with it.”
For several minutes no one said a single word. Frank was busy with
his motor, while Andy had his eyes fairly glued to the small end of
the glasses, as though he kept hoping that he would make a pleasing
discovery the very next minute.
Now even the ranch building would be found to look very small and
far to their rear, did they bother glancing back that way, which, to
tell the truth, neither of them did.
And at the same time the rough country came closer, until one could
see where the fertile plain really ended, and the sandy desert
began.
Unless one made a very wide detour it was absolutely necessary to
cross over this arid waste in order to reach the Mexican border.
Frank had been figuring it all out. He believed that Jose, being a
bold and audacious man, would not think of taking the longer route.
In the first place that course was apt to keep him exposed to the
hot pursuit which he knew he could count on as the result of his
audacious exploit. And doubtless Jose was fully aware of the
reputation those hard riding cow punchers connected with the Double
X Ranch had as trackers and fighters too, on occasion. What they had
done to the Mexican cattle rustlers must have made a reputation for
them across the border; so that Jose knew what chances he was taking
when he started in to steal his daughter, which the court had given
over into the keeping of her relative, Mr. Witherspoon.
And Andy was not a great while in making the discovery that they
were now approaching the confines of that sandy region where the sun
beat pitilessly down all through the livelong hours of the day, and
the heat must be terrific.
Up where they were they could feel nothing of the earth’s radiation,
and doubtless it would be delightfully cool.
Beyond as far as the eye could reach, it held, that same glaring
stretch of glistening sand, on the surface of which toward noon it
would be easily possible to fry an egg; indeed Andy had actually
done the same on a previous visit, when they dropped down to
discover how it felt to be adrift in the midst of a desert, he
having been put up to the game through words spoken by Buckskin.
Far away to the west he saw the tops of high mountains, but they
must have been scores of miles off. Between doubtless lay the
desert, with perhaps a stretch of the plain where the grass grew,
and even flowers could be found in their season, all the difference
being brought about by the presence of earth in the one case and
nothing but sand in the other.
On this waste nothing seemed to grow save the cactus that stood up
like giant sentinels guarding the cemetery of centuries. Here and
there one could find the skulls and bones of unfortunate animals
that had become lost in the sand storms occasionally blowing over
this heated stretch, to perish miserably from suffocation or else
subsequent thirst.
Straining his eyes Andy kept on looking, always hoping that the very
next minute might result in a pleasing discovery. If the glare
caused his eyes to burn he paid little attention to that discomfort.
All the while he was thinking how terrible it would be if they had,
after all, made a mistake in figuring out the probable way Jose
would take in trying to escape the penalty of his cruel deed. Should
he have turned aside, and continued to avoid the desert, all their
work would go for nothing.
Still, Andy had the utmost confidence in his chum’s ability to
grapple with a question like this. He felt that Frank must know just
about what would be passing in the mind of the man they were
hunting. Frank had a faculty for putting himself in another’s place,
and figuring things out from that standpoint.
And then there was another comforting thought that came to Andy.
Supposing the fugitive had done this same thing, he could not reach
the border under several days, since the desert was extensive; and
surely there would be a good chance of the hard-riding cowboys
coming up on him meanwhile.
They would of course follow directly on his trail, their practiced
eyes picking it out of the many that crossed the level stretch to
the south of the ranch buildings. And like bloodhounds on the scent,
once they had started, they would keep it up to the end.
As the aeroplane pushed on, and neared the border of the desert, so
plainly marked below, Andy gave an ejaculation that caused Frank to
look expectant.
“A pony, Frank, yes, two of them feeding there, and without saddle
or bridle to show that they have been ridden. Whatever can that
mean?” he called out, so as to be heard above the humming of the
motor.
“I think I can guess,” replied the other, quickly. “This has been a
deep-laid scheme, and no sudden fancy. Jose has made all sorts of
preparations for carrying it out with success. He knows that perhaps
his life would pay the penalty for any failure. So, you see, Andy,
chances are, he left two fresh ponies staked out here and ready for
use when he came along after riding the others for these twenty or
more miles. A quick change of saddles and bridles, and then he and
the little girl were away again, this time striking out straight
across the sand, and headed for the nearest point of the Mexican
border.”
“That sounds like you had guessed it first pop out of the bottle,
Frank,” the other went on to say, “and if it’s so, then we’re bound
to come up on him before long.”
Andy once more started to glue his eyes to the end of the field
glasses. Carefully did he scrutinize every object he could pick out
along the horizon ahead. If he had any idea that it moved, he would
stop in his shifting movement to concentrate his gaze long and
earnestly upon that one spot; but only to give a grunt of bitter
disappointment, and once more continue to scan the waste of sand
beyond.
So it went on for some time. The minutes must have seemed unduly
long to the ever anxious lad. Frank, more inclined to take things as
they came, always hoping for the best, was better able to control
his emotions. It had perhaps been twenty minutes since they reached
the border of the desert, and now on all sides they could see
actually nothing but that same dead glare of the burning sun beating
on the absorbing sand.
Frank was himself thinking that they must have reached the limit of
distance which the fugitive could have covered, even though he had a
fresh relay of ponies to help him along; when once again he heard
his cousin give utterance to that bubbling little cry that seemed to
announce a fresh discovery.
