Into the air they rose like a couple of soaring birds, and for one brief moment were flying over the rushing water. The shout of derision died on the lips of the now thoroughly frightened natives, as both the thoroughbred beauties landed fairly on the opposite bank and sped on their way, as though they had but jumped a ditch.
By their daring feat the boys had so gained upon the thieves that they were now not more than a quarter of a mile behind and gaining rapidly.
Seeing that they could not escape with their booty, the thieves turned suddenly to the left, deserting their herd, and rode as fast as their horses could carry them directly toward the chaparral that skirted the Rio Grande.
At this the boys would have drawn rein, seeing that old Bray was now within their grasp, but their attention was attracted by a shout from the opposite side of the stream which they had just crossed.
Turning their heads to see whence came the noise, they beheld a body of a dozen or more hors.e.m.e.n headed toward the ford at full speed.
"Don"t let them escape! Don"t let them escape!" shouted the leader of the band, and, without stopping to think why they should obey such an order, but feeling that there was good reason for it, the boys again took up the chase.
As they espied the hors.e.m.e.n on the opposite bank, and realizing that there was but one way to escape, the thieves turned in their saddles and simultaneously fired a shot at their boy pursuers.
The b.a.l.l.s whistled by the boys" heads, but did not stop their furious gallop. Again the thieves fired, and again the b.a.l.l.s whistled harmlessly by their heads.
But they had no chance to fire again, for the lads were right upon them.
Suddenly Donald"s hand shot forward, and his lariat sung out with lightning speed. True to its aim, it fell over the shoulders of the nearest Mexican. Wireless stopped as though he had been suddenly rooted to the spot; the Mexican"s horse dashed on riderless, and his master lay senseless upon the ground.
At the same moment Billie"s revolver cracked and the horse of the other fleeing Mexican pitched headlong to the earth, carrying his rider with him. Before he could recover himself, Billie had pulled up beside him, and, leaping to the ground, quickly bound him with his own lariat.
The boys had hardly regained their breath, when a loud cheer announced the arrival of the other hors.e.m.e.n.
"Good for you, young fellows," exclaimed the leader of the band, as he, too, sprang from his saddle. "You"ve made an important capture. We"ve been trying to get evidence against these cutthroats for weeks. I surely owe you one."
"That"s good," laughed Billie. "It"s mighty nice to have something coming. But who are you?"
"Oh, me," was the good-natured rejoinder. "I"m Captain June Peak, of the Texas Rangers, and these are part of my company."
CHAPTER III.
A DANGEROUS MISSION.
Of course both Donald and Billie had heard of the Texas Rangers, that daring body of the Texas militia which has done so much in maintaining law and order along the Mexican frontier, as well as in the lawless communities farther interior. This, however, was their first introduction to the rangers, and they gazed at the riders with considerable astonishment, their appearance not being such as would give a stranger a very good opinion of their law-abiding character.
"Texas Rangers," finally exclaimed Donald, in a tone that indicated some doubt. "Then what are you doing this side of the Rio Grande?"
"Well, I declare," responded Captain Peak, looking around at his men with a twinkle in his eye, "we must have crossed the river without seeing it. We"d better get back just as fast as we can."
"That"s right, Cap.," replied one of the men, "but you wouldn"t think of leaving these poor fellows lying on the ground, would you?"
"Sure not. Just pick them up, some of you, and we"ll get right back to our own side of the river."
The words were no sooner spoken than several of the men sprang to the ground. The two Mexicans were quickly thrown across the backs of a couple of horses, and the rangers prepared to return.
The boys had heard the words of the captain, and watched the proceedings without a word, realizing by the captain"s manner that the affair was more serious than he let on. As the men again resumed their saddles, and the captain was about to mount, Donald thought it high time to ask further questions; but he hadn"t decided just what to say before Captain Peak asked:
"How did you boys happen to be chasing these greasers?"
"They were stealing our mule-that big one there," replied Donald, pointing to old Bray. "You can see he has the Keystone brand, the same as our horses," and he indicated the marks upon Jupiter and Wireless.
"Then you"d better cut him out and come along with us," said Captain Peak. "This won"t be a very healthy place for you much longer."
"No?" And the boys looked at the captain inquiringly.
"No; there"s going to be trouble along the border, and it may break out any minute. That"s why these horse-thieves are so bold; and that"s why we are on this side the river, where we really have no business. But these fellows have become such a nuisance that when we saw them leaving the _casa_ a little while ago we couldn"t resist the chance of getting them. We shall turn them over to the Mexican authorities at the first opportunity, and I hope you boys will be on hand to give your testimony against them."
"If they are really horse-thieves," replied Donald, "we shall be glad to help bring them to justice; but we are only travelers, and don"t wish to be delayed on our journey any longer than necessary. We have a companion and another mule back there in the chaparral."
"All right," replied Captain Peak, "we"ll ride back that way and see that no one disturbs you. Then we"ll all get into town as soon as possible. It"s only six or seven miles."
Acting upon Captain Peak"s advice, the boys cut old Bray out from the rest of the drove, and in company with the rangers, galloped back toward the place where they had left Adrian. It is hard to say which was the greater, his pleasure at seeing his companions with old Bray in their possession, or his surprise at the numerous company that was with them.
As they rode leisurely toward Presidio, after crossing to the American sh.o.r.e, Donald explained to Captain Peak how they happened to be so far from home. He was much interested in their story, and when they reached town introduced them to the officials, both civil and military. The captured horse-thieves were locked up in jail and the boys went home with Captain Peak, who invited them to spend the night with him at the hotel.
"I tell you," exclaimed Billie, as they sat on the porch that evening after supper, "a woman"s cooking surely does taste good! Why, just think, we haven"t had a bite for most a month that we didn"t cook ourselves."
The following morning the boys were awakened by a big commotion outside, and, looking down the street toward the jail, saw that it was surrounded by a great crowd. They hastily dressed themselves and rushed out of the hotel. Almost the first man they met was Captain Peak.
"What"s the matter?" asked Billie.
"There has been an attempt to rescue the prisoners, but it did not succeed."
"Who did it?" queried Adrian.
"We are not exactly sure, as the rescuers mounted their horses as soon as they were discovered, and managed to get away. Some of the rangers are after them, however, and I hope will get a trace of them."
"They must have been pretty bold to come into a town as big as this,"
said Donald.
"So they are; but, as I told you yesterday, there is likely to be a lot of trouble the other side of the river, and the authorities are having their hands full looking after possible revolutionists. As a result lesser culprits go free."
"That must make a lot of trouble on this side," suggested Adrian.
"It does, for, in addition to watching for horse and cattle thieves, we have to keep our eyes open for gun runners."
"What do you mean?" asked Billie. "What are gun runners?"
"Would-be revolutionists, who smuggle quant.i.ties of arms into Mexico without the knowledge of the Mexican officials."
"I didn"t know it was our business to stop that. I thought anybody could buy arms to sell in Mexico?" said Adrian.
"So they can; but these arms would not be for sale. They would be for arming bands of men to overturn the government. We are under no obligation to stop it, but, as we want law and order along the border, we always try to help the Mexican authorities," explained Captain Peak.
"But there come my men now," he continued, as several hors.e.m.e.n turned into the main street.
