The Border Boys Across the Frontier | Page 3

for the departure of the professor's
expedition. A short time later, "Professor Wintergreen's Haunted
Mesans," as the boys insisted on calling themselves, had likewise
started on their quest. With them, at Jack Merrill's invitation, went
Walter Phelps, the son of a ranching neighbor of Mr. Merrill. Walt, it
will be recalled, had shared the perils and adventures of the boys across
the border, as related in the previous volume, and had been the
instrument of piloting them out of the mysterious valley in which Black
Ramon kept his plundered herds.
Mr. Merrill's last words had been ones of caution.
"Remember, boys, that if this trouble in Mexico attains real proportions,
life and property along the border may be in great danger. In such a
case, it will be your immediate duty to turn back."
"But, Dad," Jack had said, "you don't expect that plundering insurrectos
would have the audacity to come northward into the Playas?"
Mr. Merrill laughed.
"I didn't say there was any danger even here, my boy. Least of all, out
in that barren country. If there is an insurrection, it will doubtless be
put down without any trouble, but it is always well to be prepared."
Like his brother ranchers along the border, Mr. Merrill at that time had
no idea of the seriousness or extent of the insurrection. Had he had, he
would, of course, have prohibited the party leaving the ranch. As it was,
he, in common with his neighbors, deemed the insurrection simply one
of those little outbreaks that occur every now and again in Mexico, and
which hitherto had been promptly squashed by Diaz's army. And so,

with no real misgivings, the party had bidden the bluff, good-natured
rancher good-by, little dreaming under what circumstances they were to
meet again.
But all this time we have been allowing our party to travel on without
bestowing any attention upon them. As the afternoon wore on, Coyote
Pete began to feel real apprehension about reaching their destination
that evening. Walt Phelps' fear about the water had been verified. The
supply was getting low. Provided they could "pick up" the mesa they
were in search of before sundown, however, this was not so serious a
matter as might have been supposed. Coyote Peter knew that there was
a well at the mesa, the handiwork of the ancient desert-dwellers.
The really serious thing was, that although they had apparently been
traveling in the right direction, they had not yet sighted it. The
cow-puncher knew, though he did not tell his young companions so,
that they should long since have spied its outlines. Of the real
seriousness which their position might shortly assume, the boys had as
yet, little idea. Coyote Pete was not the one to alarm them unless he
was convinced it was really necessary.
Suddenly, Jack, who had been riding a little in advance of the rest, gave
an exclamation and pointed upward at the sun.
"Say, what's the matter with the sun?" he exclaimed.
"Sun spots, I suppose," put in Ralph Stetson jokingly.
"I see what you mean," spoke up the professor; "it has turned quite red,
and there seems to be a haze overcasting the sky."
"It's getting oppressive, too," put in Walt Phelps. "What's up, Pete?"
The cow-puncher had, indeed, for some time been noticing the same
phenomenon which had just attracted their notice, but he had hesitated
to draw their attention to it. Now, however, he spoke, and his voice
sounded grave for one of Pete's usually lively temperament.

"It means that ole Mar'm Desert is gettin' inter a tantrum," he grunted,
"and that we're in an almighty fix," he added to himself.
"Is it going to rain?" inquired Ralph Stetson, as it grew rapidly darker.
"Rain?" grunted Pete. "Son, it don't rain here enough to cover the back
uv a dime, even if you collect all the water that fell in a year. No, siree,
what's comin' is a heap worse than rain."
"An electric storm?" queried the professor.
"No, sir--a sand storm," rejoined the cow-puncher bluntly.
CHAPTER II.
THE SAND STORM.
As he spoke, a queer, moaning sort of sound, something like the low,
distant bellow of a steer in pain, could be heard. The air seemed filled
with it. Coming from no definite direction, it yet impregnated the
atmosphere. The air, too, began noticeably to thicken, until the sun,
from a pallid disc--a mere ghost of its former blazing self--was blotted
out altogether. A hot wind sprang up and swept witheringly about the
travelers.
"Ouch!" exclaimed Ralph Stetson suddenly. "Something stung me!"
"That's the sand, son," said Coyote Pete. "The wind's commencin' ter
drive it."
"Is it going to get any worse?" inquired the professor anxiously.
"A whole lot, afore it gits any better," was the disconcerting reply.
"What'll we
