"You can see pretty nearly the whole of the valley from the top of Snake Mountain," spoke Dick, when he and Bud had joined in the laugh at Nort's airship idea. "If one of us could be up there—"

"We'd have to be there all the while!" interrupted Bud. "There's no telling when the rustlers will come. Talk about being on the watch! It's all right to say so, but how you going to work it?"

Dick suddenly uttered an exclamation.

"What's the matter?" his brother wanted to know. "See a snake?"

"No, but I've got the idea! A watch tower! Why not build one at our camp—or up on the side of the hill back of the reservoir? We could make it of logs—high enough to give us a good view. It wouldn't be much of a trick to climb up in the watch tower three or four times a day and survey the place. A watch tower is the thing, Bud!"



CHAPTER XII

IN SPITE OF ALL

Nort and Bud stared at Dick for several seconds without making any remark. They were sitting on their ponies, completely baffled by the manner in which the trail of the rustlers had suddenly "petered out." And they had been about to turn and go back to camp when Dick made his enthusiastic remark.

"A watch tower?" repeated Bud.

"Sure!" declared his cousin. "We used to build 'em when I belonged to the Boy Scouts. Remember, Nort?"

"Sure! It begins to come back to me. We used to bind saplings together and make quite a high perch. The idea was that you might be able to see your way if you got lost," he explained to Bud.

"Not a bad idea, either," commented the western lad. "I begin to see your drift, as the wind said to the snowstorm. You mean to build a sort of high platform up by the reservoir, Dick?"

"Yes, a watch tower of logs, strong enough to hold one or two fellows. You could make ladders so's we could reach the top platform, or we could scramble up if we left hand and foot holds where we lopped the branches off saplings." "That's right!" cried Bud, now almost as enthusiastic as was his cousin. "And with a good pair of glasses, or a telescope such as dad has at the ranch, we could see all over the valley."

"Let's make it!" cried Nort, and the matter was settled as quickly as that.

Something of the excitement that had moved them must have been visible on the faces of the boys when they returned to camp, for Old Billee, greeting them in the absence of the other cowboys, asked:

"Did you land 'em, Bud?"

"Who; the rustlers? No. Couldn't see where they'd vanished to any more than, as one of the boys said, as if an airship had been used. But we got an idea, Billee."

"They're valuable—sometimes," agreed the veteran cow puncher cautiously.

"We hope this one is going to be!" frankly laughed Bud. "We're going to build a watch tower, and take turns staying up in it with a telescope. We can see almost the whole valley if we get high enough, and as there aren't many patches of woodland where the rascals can hide, we hope to spot the rustlers as soon as they begin their tricks."

"Well, you may do it," and again the cowboy was very cautious. "I never heard of cattle rustlers bein' caught that way, but when other means fail, try suthin' diffrunt! We'll tackle th' tower!"

And as the other cowboys, even Four Eyes, pronounced the scheme worth trying, it was put into operation. Mr. Merkel, to whom Bud communicated his idea over the telephone, rather laughed at it.

"How about nights?" asked the ranchman. "No matter how high you are up after dark you can't see any better."

"But most of the raids of the rustlers have been in daylight," declared Bud.

"It's about fifty-fifty," his father told him. "However, it won't do any harm to try it. Only don't fall off that watch tower of yours. I'll come out and look at it when you get it done."

The boy ranchers and their cow punchers started work the next day. Dick and Nort remembered, in a dim way, how, as Boy Scouts, they had helped erect towers, hastily constructed of saplings. Their recalled knowledge, together with the natural adaptability and skill of the cowboys, finally succeeded in there being evolved, and erected, on the aide of the valley rather a pretentious tower. "It must look like an oil well derrick from a distance," observed Nort, when it was al most completed.

"What do we care how it looks, if it does the trick?" retorted Bud. "From that perch, and with this telescope dad let me take, I can tell the color of a cow clear to the end of our valley."

There was no question but what the watch tower did provide an excellent vantage point. From its top platform, reached by rude ladders, any unusual movement in the entire valley could be seen during the day.

It was planned that the boys—and by this I mean the hired cowboys also—should take turns in being on watch in the tower during certain periods each day. A schedule was drawn up by Bud and his cousins, and put into operation as soon as the tower was completed.

"And now we'll catch the rustlers at work!" boasted Bud.

But alas for their hopes! In spite of all their precautions, and setting at naught the hard work of constructing the tower, there was another raid on the cattle in Happy Valley, about a week after the wooden perch had been set up.

It was not a disastrous raid, and only a half score of steers were driven off from one of the more distant herds. But the raid took place, and at night. It was discovered one morning, just as Bud was going up into the tower, where a seat and sheltered place had been built.

"They fooled us, Bud," said Old Billee, riding in from a distant part of the valley.

"Fooled us? How?"

"They let us watch by day, an' they come an' robbed by night! Another bunch of steers gone!"

"Well—by Zip Foster!" cried Bud, slamming his hat down on the ground. "I'm getting tired of this!"



CHAPTER XIII

THE SIGNAL

"What's the matter?" cried Dick, hastening from the tent where he had been making a new loop on his lariat, in preparation for practicing some of the stunts worked by Four Eyes.

"Have you discovered something from the tower?" asked Nort.

"Yes, I've discovered that the tower isn't any good!" exclaimed Bud with emphasis. "Oh, it isn't your fault, Dick," he went on, as he saw that his cousin looked a bit crestfallen. "The tower is all right."

"Then you saw some rustlers from it?" asked Nort.

"No, that's the trouble," said Bud, ruefully. "We didn't see them but they were here all right—last night. Tell us about it, Billee," he requested.

"Well, there isn't an awful lot to tell," said the veteran cow puncher. "I was just prospectin' around, over on that new growth of Johnson grass, like you told me to, an' I saw where a steer had been killed, an' they had eat most of it, too, by th' signs."

"You mean the rustlers?" asked Nort.

"Rustlers, Greasers, Del Pinzo's bunch—anything you like t' call 'em," asserted Billee. "Somebody, that hadn't any right t' do it, druv off our cattle!"

"And I say it's about time it was stopped!" declared Bud with as great positiveness as before. This time he picked up the hat he had dashed to the ground and dusted it off. "I'm going to do something desperate!" he declared.

"What, son?" asked Old Billee mildly. "They's allers been rustlers in this cow country, an' they'll allers be some, I reckon. Course if you can git 'em in th' act, they's nothin' t' do but shoot 'em up. But when you can't git 'em—"

"That's what I'm going to do!" declared Bud. "I'm going to get on the trail of these rustlers and clean 'em out! Tell us more about it, Billee. No use getting up in the watch tower now," he added, gloomily enough. "We've got other work cut out for us. Go ahead, Billee! Shoot!"

"Let me give you a word of advice first, Buddy boy," spoke the veteran cowboy as he slowly got off his pony, an act of grace for which the animal was, doubtless, duly thankful. Billee was no featherweight, though he was as active as need be, in spite of his bulk.

"What's the advice?" asked Bud good-naturedly. His first hot anger was beginning to cool.

"Well, my advice is to leave these rustler alone," said Old Billee. "They's allers been rustlers here an' they'll allers be here. Every cow country has 'em. They're like th' old pirates that used t' hold up th' ships. Taking tribute, so t' speak."

"But our country didn't pay that tribute long!" exclaimed Dick, remembering the brilliant exploits of Decatur against the corsains of Algiers, Tunis and Tripoli. "'Millions for defense, but not a cent for tribute'!" quoted Dick in a ringing voice.

"That's what I say!" chimed in Nort.

"Well, it is tribute, in a way," admitted Old Billee. "I was going t' say if you'd let th' rustlers make off with a few steers now an' then it would save trouble. They're used t' takin' a few. But if you fight 'em then they'll make a big raid with a big gang, an' mebby, take all you got, Bud!"

"I'd like to see 'em try it!" cried the western lad. "And I won't sit by and have my cattle stolen; will we, fellows?" he appealed to his cousins.

"Not on your life!" declared Nort and Dick.

"Well, I shore do like t' hear you talk that-a-way," said Old Billee. "I didn't think you'd do it. Course it ain't no fun t' sit still an' let these onery Greasers walk off with your cattle. But, as I say, it's sometimes easier'n 'tis t' fight 'em. Lots of th' ranchmen do pay tribute in a way. Your father was one of th' fust t' fight 'em, Bud, but even he has sorter give up now, an' he don't raise no terrible row when a few of his steers get hazed off."

"Well, dad has more, and losing a few doesn't put a crimp in him," said Bud. "It's different with us, and I'm not going to stand it. Zip Foster wouldn't and I'm not going to!" and again he dashed his hat on the ground, thereby startling Billee's horse.

"Say, why don't you get Zip Foster over to help chase the rustlers?" asked Dick, slyly nudging Nort. They had long been trying to get Bud to a "show down" on the identity of this mysterious personage.

"Oh, I reckon we can do it ourselves," and Bud seemed to regret mentioning the name of his favorite.

"Just what are you aimin' t' do, son?" asked Billee, as Snake and Yellin' Kid rode up, ready for their day's work out on the range among the cattle.

"I don't exactly know, but it's going to be something and something hard!" asserted Bud. "Are there any clues over there, Billee, to give us a lead?"

"Not many, Bud. Just th' usual. They come onto a few scattered steers, killed one roasted what they wanted of it, slipped off the hide an' left th' rest t' th' buzzards. Then they druv off th' remainder. I didn't foller th' trail, for I could see they was half a dozen rustlers in th' bunch, an' it ain't exactly healthy for one man t' trail a crowd like that even if he was a two-gun man, which I don't lay no claim t' bein' no how," concluded the veteran modestly. They all knew he would be brave enough in an even fight. But they all recognized the fact that it would have been foolish for him, alone, to have attempted to trail a gang of desperate men.

"Well, I'm going to see what we can do," Bud declared. "If you've sized up all there was to see over there, Billee," and he nodded in the direction of the latest raid on Diamond X Second, "there's no use in me going over. I think I'll go have a talk with dad," he concluded. "I want action!"

"So do we!" added Dick.

"Then come along!" invited his cousin.

A little later the boy ranchers were riding out of the valley, on their way to the main ranch of Diamond X. They would not be back until late that night, or, possibly, until the following morning, for Bud wanted to have a good, long talk with his father, and decide on some plan of action, that would drive out the rustlers and keep them away.

As Old Billee had said, probably an older and more experienced rancher would have put up with a few losses for the sake of peace and quietness. But Bud, like most lads of his age, was impulsive. And, as he had said, the loss of even a few steers meant possible failure to him and his cousins, just starting in the ranch business as they were.

"Was that a black one?" suddenly asked Bud, as Nort's horse shied at something.

"A black what!" Nort wanted to know.

"A black jack rabbit that ran across the trail in front of you just now," Bud resumed. "If it was, it will bring bad luck, as Old Billee would say," and he laughed.

"No, it was a sort of gray one, part white," Nort answered, for it was one of those immense hares that had leaped across the trail, almost under the feet of his pony.

"That means we'll have part bad luck and part good," declared Dick.

And some hours later, when they had reached Bud's home, and Nell was serving peach pie and glasses of milk to the boy ranchers, Nort paused long enough in his eating to remark:

"This is the good luck, Bud."

"You declaimed something that time!" agreed his brother.

Mr. Merkel listened to what Bud and his cousins told them of the raids on Happy Valley.

"Well, you haven't suffered any more than the average ranchman, just starting in," said Bud's father. "The rustlers always seem to pick on a newcomer."

"Well, they'll find I'm a sort of prickly pear to pick on!" asserted Bud. "Dad, can't we clean out these rascals?"

"Well, it's your ranch, Bud! You can do anything you like, within reason, but I wouldn't like to see you take any foolish risks."

"There's got to be some risks," declared Bud. "I'm not looking to get out of 'em. But don't you think it would be a good thing if we could get rid of this Del Pinzo gang for good?"

"Sure, Bud. I'll give you all the help I can, and I'll spare you one or two more men if you need 'em—for a time, that is, as we're pretty busy here."

"All right. When we're ready I'll call on you," said Bud, as though he had great plans in preparation. As a matter of fact, as he admitted later, he really did not know what he was going to do, but he was not going to admit that to his father. In other words he was "putting up a bluff," and I have some reason for suspecting that Mr. Merkel knew this. However he gave no sign. In spite of the pie, cake and other good things set out by Nell and Mrs. Merkel, Bud and his chums decided to ride back to their camp that night. It was dark at the start, but the moon would be up later, and the trail was well known.

The boy ranchers rode leisurely along, for there was no special hurry in getting back. It might reasonably be supposed that the rustlers would not again make a raid within a few days at least. And Old Billee, Yellin' Kid, Snake Purdee and Four Eyes, to say nothing of Buck Tooth, were well able to look after matters in Happy Valley.

And thus proceeding at a foot pace, it was well after midnight when the boys started down the last slope that led into the valley proper. In daylight it would have been possible, from this part of the trail, to have observed the tents and the reservoir. But now all was shrouded in darkness.

No, not altogether darkness, for as the boys rode forward there suddenly glimmered in the gloom a light, high up in the air. At first Bud thought it was a star, but a moment later as it moved from side to side, and then up and down, he exclaimed:

"Look, fellows! A signal!"

"Signal!" repeated Dick.

"Yes. Over at our camp! See! There's a light on our watch tower."

"Maybe there's been another raid!" said Nort.

"Or going to be one!" spoke Bud, grimly.



CHAPTER XIV

FOUR EYES—NO EYES

Thudding along, their ponies seemingly as eager to reach the ranch camp as were the boys themselves, Bud, Nort and Dick raced toward the mysterious light. For that it was mysterious they all agreed, and that it was flashing from the top of the watch tower they had built to spy for rustlers was another conclusion.

"Do you s'pose it can be Old Billee, or Yellin' Kid signalling to us?" asked Nort, as he galloped between Bud and Dick.

"They wouldn't know we were coming," Bud answered. "I said we might not be back until to-morrow."

"That's so. But who do you think is signalling?" asked Dick.

"And who are they signalling to?" Nort wanted to know. "That's what we've got to find out," spoke Bud, grimly. "And it's what we're going to find out in a short time! Come on, Sock!" he called to his pony. "This is only exercise for you!"

Indeed the animals had not been hard pressed, and this burst of speed was rather a relief than anything else. Together the boy ranchers hastened toward their camp.

For some time the lantern—it was evidently that and not a torch—was waved to and fro, parallel to the horizon, and again up and down. It was so evidently a signal, or a series of them, that the boys no longer questioned this theory.

But who the signaller was, and to whom he was flashing his message in the dark night—those were other questions. And they were questions that needed answering.

"It must be one of our men," remarked Bud. "No one else could get into camp and climb the tower without a row being raised."

"How do you know there hasn't been a row?" asked Dick.

"What do you mean?" countered Bud.

"I mean there may have been a fight," Dick went on. "Maybe the rustlers have surprised our camp, put Yellin' Kid and the rest of our bunch out of business and are signalling to the main crowd to come up and drive off the cattle. I might as well say that as think it," he added. "And that's what I've been thinking the last few minutes."

This dire suggestion struck Bud and Nort silent for a moment. And then, more because he did not want to believe it, than because he did not believe it possible, Bud exclaimed: "I don't believe any such thing!"

"I don't want to believe it!" said Nort. "But of course there may have been a fight."

"If there was, there's a lot of dead Greasers and rustlers scattered around, you can depend on that!" declared Bud, grimly.

"Yes, I reckon Old Billee, Snake and the rest would give a good account of themselves," asserted Dick.

"And they wouldn't be taken by surprise, either," added Nort.

"Not likely," affirmed his cousin.

Again they directed their gaze toward the flashing signal on the tower. Once more they saw it slowly raised and lowered, and then swept from side to side.

"Are they spelling out a message in Morse or Continental code?" asked Bud.

"It does look like the Morse," said Nort. "We learned that when we were Boy Scouts. I can make out some letters, but they don't spell anything that has any sense to it."

"Maybe it's in Spanish," suggested Bud, who was not familiar with the method of spelling words by flags or lanterns. "There's a lot of Greasers around here who don't know anything but Spanish."

"That's so," agreed Nort. "I didn't think of that. I'll try and catch what the next word is, and maybe you'll know it, Bud," for the western lad understood some of the language of Mexico.

But just when Nort was directing his attention to the signal flashes Dick, who had ridden on a little ahead, suddenly called:

"Is that a fire?"

They looked to where he pointed and, for a moment, thought it was another blaze in the dried grass. For the eastern skyline that had been only dimly seen was now outlined in a red flare.

"It is a fire!" asserted Nort.

"It's the moon rising!" said Bud.

And so it proved. The moon was coming up, big, round and red, and, when below the horizon, cast a reflection not unlike a fire. The boys laughed with relieved spirits as they rode on. But when Nort next directed his attention to the flashing lantern it was no longer signalling. In the direction of the watch tower there was only blackness, for the moon's rays had not yet reached it.

"Looks as if they'd quit," said Dick.

"Maybe they thought the moonlight would give 'em away," suggested Nort.

"We'll soon know about it," declared Bud, with grim meaning.

They were now within a short distance of the tents, gleaming white in the moonbeams. From one of the larger canvas shelters shone a ruddy light, showing dark figures within. And then was borne to the ears of the boys the sound of laughter.

"That doesn't seem to indicate a raid or fight," spoke Nort.

"You can't be sure," Bud remarked. "We'd better be careful. Let's dismount and go on foot."

They left their ponies, throwing the reins over the heads of the animals, and cautiously approached the tents of the cow punchers on foot. This tent was, practically, the "bunk house," the assembling place of the men after their hours of work. But before the boys reached this their approach was evidently heard. For a figure came to the flap and a challenging voice called:

"Who's there?"

"Old Billee!" cried Bud, as he and his chums recognized the tones, and with the recognition came a sense of relief.

"Oh, you're back; are you, Bud?" asked the veteran cowboy. "I thought I heard some one."

"Who's up on the watch tower with a lantern?" called Bud, once it was certain that no disaster had occurred.

"Watch tower?" repeated Yellin' Kid, coming to the flap to stand beside Old Billee.

"Lantern?" added Snake.

"Somebody's signalling," went on Bud.

"You'd better come out and we'll have a look. Are you all here?"

"All of us," answered Old Billee. "Come on, Four Eyes!" he cried. "Tumble out of your bunk. There's somethin' doin'!"

"Four Eyes must have gone to bed early," said Bud to his cousins as they stood outside the tent. For Billee's call indicated that the spectacled cowboy had retired.

"Hi! Four Eyes!" shouted Yellin' Kid, in a voice that would have awakened the proverbial Seven Sleepers. "Turn out!"

There was a moment's pause, during which Buck Tooth came up to the bunk tent from his own special nook for sleeping. And then, the voice of Snake Purdee announced:

"Four Eyes isn't here!"

"Isn't here!" repeated Billee. "Why, I saw him turn in a while ago, when we started t' play cards."

"He isn't here now," declared Snake. "His bunk is empty, and he didn't go out the front way, I'll wager on that. There's something queer going on all right!"



CHAPTER XV

A BIG RAID

Into the bunk tent of the older cowboys crowded the young ranch lads. Doubt, suspicion and wonder mingled in their minds, and foremost of all were two outstanding matters—the mysterious signalling light, and the disappearance of Four Eyes—if, indeed, that individual had really taken himself off.

"Are you sure he was here?" asked Bud, when, after the first break of surprise, questions were in order.

"Sure," replied Yellin' Kid. "We all come in here, after th' chores was done, t' have a friendly game of cards an' smoke. We didn't look for you back until late, if at all."

"And was Four Eyes with you then?" asked Nort.

"You couldn't exactly say he was with us," replied Snake. "An' yet he wasn't away from us. He pretended he didn't want t' play cards, an' he said he was so doggoned tired an' sleepy that he was goin' t' turn in. I told him that bein' in th' same tent with a whisperin' infant like Yellin' Kid, wasn't perzactly healthy for sleep, but Four Eyes said he didn't mind. So he turned int' his bunk, an' pulled th' covers tip over his head, though I don't see how he stood it, for it isn't winter, not by a long shot, an' this place was full of smoke. Anyhow he done it, an' t' keep th' light out of his eyes, so he said, he pulled a chair up in front of his bunk like you see it now, an' stuck his coat over it."

Snake pointed to a chair, now twisted awry from in front of the cot that the missing cowboy had occupied. His coat, draped over the back, effectually screened him from observation when lying on the bed.

"He did that so's he could slip out an' get away!" spoke Yellin' Kid, justifying the sarcastic name of "whispering infant," that Snake had bestowed on him.

"But how did he get out?" asked Dick.

"And what for?" Bud wanted to know,

"He got out this way!" said Old Billee quietly, as he leaned over the cot and pushed with his hand against the side of the tent. A right-angled opening was disclosed, cut with a sharp knife. The loose point was at the bottom, and once Four Eyes had slipped out, the cut flap hung down in place, not disclosing, in the dim light, that the canvas had been cut.

"He got out that way," went on Old Billee, "because th' tent sides, bein' fast t' th' board floor, wouldn't let him crawl out very easy. He's a slick one, Four Eyes is!"

"But why should he slip out this way? Did he do anything? And who was doing that signalling?" exclaimed Bud.

"I reckon you'll find, son, that the signallin' an' th' vamoosin' of our late friend Four Eyes had some connection," spoke Old Billee. "We, bein' intent on our game of cards, didn't know nothin' at all 'bout it till you fellows rode up. Now it's about time we got int' action!"

"You win!" declared Yellin' Kid loudly. "There's suthin' queer prospectin' around these diggings an' I'd like t' know what it is!"

"I guess we all would," spoke Bud. "And we'd better start right in to find out about it. Come on, boys," he called to his cousins, but the older cow punchers took the invitation to themselves also, and soon, with lanterns and flashlights (which handy little contrivances the boy ranchers nearly always carried) they began the search.

First they made sure that Four Eyes was playing no trick on them by hiding under one of the cots in the bunk tent. Though, as Bud pointed out, it would pass the bounds of fun to have cut the canvas shelter as it was cut.

But no trace of Four Eyes was to be found.

"He's gone, hide, hair, horns, brand an' everythin'!" was the way Old Billee expressed it.

"How about his horse?" asked Nort.

"He didn't get his black one back," remarked Snake. "But he may have sort of helped himself to one of yours, Bud."

This was found to be the case when the corral was visited. It could hardly have been expected, in that country of great distances, that the missing cowboy would not take a horse.

"And now let's have a look at the tower," suggested Bud, when a rapid survey, under the fitful moonlight, had been made in the vicinity of the camp, and no trace of the missing man discovered. "Some one was signalling from up there, and it must have been Four Eyes."

"It could have been some one else," suggested Dick, not because he believed that, but because he wanted to sift all the evidence and get to the bottom of matters.

"Yes, it may have been a wandering cowboy, Greaser or some Indian, far from his native reservation," Bud admitted. "But I'm saying it was Four Eyes, though why he did it I can't imagine."

Nor could any of the others. Or, if they had a theory, they did not give voice to it, though, afterward, one and all said they had associated the missing cowboy with the rustlers.

But a search on and near the hastily-built watch tower disclosed nothing. On the top platform, whence, doubtless, the signalling lantern had been waved, no light was found. There were burned matches and cigarette stubs, to be sure, but these were as much the discarded property of Yellin' Kid or Snake, as of Four Eyes, for they all had taken turns doing sentry duty, and, as it was lonesome up on the high perch, smoking was indulged in.

"Well, he's away, and that's all there is to it," said Bud, when the search was over. "Now all we've got to do is to wait for something to happen."

"Do you think something will happen?" asked Nort.

"Well, things have been happening ever since we came out here," observed Dick. "First it was the finding of the Triceratops. Then it was the water fight in the mysterious tunnel, and now it's the rustlers after our cattle. Isn't that enough to happen?"

"Oh, yes," admitted Nort. "But I thought Bud meant something special was about due."

"It wouldn't surprise me if it did happen," declared the western lad. "But I wasn't thinking of anything out of the usual. Only the combination—Four Eyes missing and us seeing the light makes me suspicious. So I'm ready for anything."

"And I'm ready for my bunk!" declared Dick, with a yawn. "It's most morning! Let's turn in!"

They did, but none of the boy ranchers rested well, for they were too worried.

What did it all mean? And what events portended? These were questions they wished soon would be answered.

The morning did not bring the return of Four Eyes, nor in the better light were any more clues discovered at the Watch Tower. Looking from its height, over the peaceful valley, the boy ranchers saw nothing evil, and there was no hint of coming disaster other than in the suspicions engendered by the recent strange happenings.

"Do you suppose that signalling could have meant an Indian uprising?" asked Nort.

"Cracky! If it does we'll have to fight 'em, won't we?" asked Dick, with sparkling eyes.

"I don't imagine the Indians around here have any notion of rising," said Bud. "They have done such things, years ago, but I doubt if they have enough spirit left for it now. They are too well satisfied with their lot. But of course it's possible, though Buck Tooth says he doesn't look for anything of the sort. But then he's been with white men so long he isn't really much of an Indian any more."

"Well, if there's any Indian fighting to be done I want to do my share!" declared Dick, and his brother nodded in confirmation.

But as several days passed, and nothing more happened than the usual hard work on the ranch, the apprehensions of the boys began to disappear. They made inquiries about Four Eyes, but no one on the neighboring ranches had seen him. Mr. Merkel expressed himself as greatly disappointed in the character of the cowboy he had sent to his son.

"Maybe you got off lucky, with only a cut tent," the ranchman observed. "But better be on your guard, son."

"We will, Dad," replied the western lad.

It was about a week after the signal lights had been observed, the disappearance of Four Eyes coinciding, that, as Bud and his cousins were eating "grub" in camp one noon, they heard shots fired off to the north, and in the direction of the trail between Happy Valley and Diamond X ranch.

"What's that?" asked Nort, starting from his seat.

"Stampede, maybe," suggested Dick, for the boys knew that the older cowboys were in that direction, rounding up a small herd which had been purchased and that was to be shipped east. Bud hurried to the entrance of the tent and what he saw caused him to cry:

"Come on, boys! It's the rustlers again! They're making a raid! Get your guns!"

In less time than you would have deemed possible, unless you had seen it, the boy ranchers were in the saddle, and were galloping toward the scene of the shooting. The sounds were more plain, now, and as they straightened out on the trail they could see where a fight was in progress.



CHAPTER XVI

ON THE TRAIL

Yellin' kid, Old Billee and Snake Purdee were standing off the attacks of more than double their number. This was the spectacle that greeted Bud, Nort and Dick as they swept up the trail and toward the sound and sight of the firing. For now they could see the little puffs of smoke which preceded the discharges of the guns. Light, traveling faster than sound, brought to the eyes of the boys the puffs of burned gunpowder before the report echoed.

"This is the meaning of that night-signalling!" cried Nort, as he galloped beside his cousin.

"Looks so," was the answer. "They're getting bold and desperate to try to rustle our stock in the day time."

"You said it!" exclaimed Dick, as he looked to make sure he had a good supply of cartridges.

As the boy ranchers drew nearer the scene of the conflict they could observe that the herd, which their cowboys had been driving in, was now in confusion. And no wonder, with more than half a score of wildly-excited men riding among them, shouting and firing heavy revolvers.

For distant shouts borne to the ears of our heroes told of the excitement under way. As nearly as Bud, Nort and Dick could tell from their vantage point, eight or ten Mexicans, Greasers or other undesirable characters, had swept down from the north on Old Billee, Snake and Yellin' Kid as the latter were hazing the cattle along to the trail which led to the distant railroad station. Naturally the cowboys of Happy Valley had turned on their attackers and the fight resulted.

It was evidently the intention of the rustlers (for of their character there was little doubt) to drive off as many of the Diamond X Second stock as possible. And if they had to kill or maim the watchers it meant little to them.

But, so far, none seemed to have been seriously hurt, for no horses were running around with empty saddles, and no bodies were prostrate on the ground. I think, if the truth were known, that the first shooting on both sides was so wild that no one thought to take accurate aim, which is difficult on the back of a rushing cow pony, and with a heavy .45 gun.

It was, essentially, a running fight and Bud, Dick and Nort were urging their ponies forward as rapidly as possible to get their share of it. However, they were not destined to come to close grips with the enemy. For as they drew nearer to the scene of conflict, their guns out, and eager in their own hearts for action, yelling encouragement to their comrades, the boy ranchers saw their foes suddenly swing away.

This sudden giving up on the part of the rustlers was due either to a signal from one of their number that the raid was a failure, or else they saw reinforcements, in the persons of the boys, and had no desire for a more nearly even battle.

At any rate, with wild yells, the rustlers pulled up their ponies, and turned off down the trail, riding at break-neck speed. Yellin' Kid and Snake, with shouts of defiance, swept after them, and might have caught them except for what happened to Old Billee. The veteran suddenly reeled in his saddle, and would have fallen, except that, as he lagged behind his two companions, Bud rushed up to him and held him in place.

"Are you hit, Billee?" Bud cried.

"Only just a scratch, but it seems like it took th' tucker out o' me mighty suddin," gasped the old man. "Beckon I'd better get down. I'd 'a' fallen if you hadn't rid up, Bud."

"That's what I thought when I saw you reel."

By the time Bud, with his cousins, was helping Old Billee to the ground, Yellin' Kid and Snake turned and saw what had happened. They then gave up all thoughts of pursuing the retreating rustlers and came riding back, winded and excited, but none the worse for their encounter with the rascals.

"Did they get you, Billee?" asked Snake, a gleam in his eyes that portended no good to the perpetrators of the deed if he ever caught them.

"Only a scratch," said the old cowboy, but rather faintly. He put his hand to his side, and quickly opening his garments, as he sat on the ground, his friends saw that the wound was more than that.

However, the bullet had glanced off the ribs, and aside from having lost considerable blood, which accounted for his weakness, Old Billee was little the worse off.

"I think we got one of 'em," announced Snake. "I saw him holdin' pretty desprit like t' his saddle."

"What started it? Who were they?" asked Bud, as the last of the raiders swept out of sight amid the rolling hills of the valley.

"Oh, some of Del Pinzo's gang, you can make sure of that," said Yellin' Kid. "They just rid down on us an' started t' fire. We saw what their game was all right, an' come back at 'em. They didn't get one steer, Bud!" he added, proudly enough.

"That's good," said the boy rancher.

"But they did an awful lot of shootin'," added Snake. "I thought sure we'd all be hit, but Old Billee was th' only one what got it. I never heard so much Fourth of July since I was a kid."

"It was a lot of shooting, according to the results," spoke Bud, as he watched Snake bandaging Billee's wound, for the cowboys carried a primitive first-aid kit. "I wonder if that meant anything?"

"What do you mean?" asked Nort.

But Bud did not answer.

Making sure that none of the cattle had been hit, and managing, after rather strenuous work, in quieting the herd, the boy ranchers and their friends started back toward camp, Old Billee taking it as easily as possible, for his side was getting stiff and painful.

While they were yet some distance away from the white tents that corresponded to the usual ranch buildings, Bud and his companions saw riding toward them a solitary figure.

"It's Buck Tooth," declared Dick.

"And if he doesn't bear evil tidings I miss my guess," murmured Bud.

Evil tidings they were, in very truth. For as the Zuni came near enough he was seen to be much excited. Drawing rein, he made a sweeping, comprehensive gesture with one hand, toward the south end of the valley, and exclaimed: "All gone!"

"What's all gone?" asked Bud, a great fear clutching at his heart.

"Cattle!" answered the Indian. "Rustlers drive 'em all 'way, while you shootin' off there!" and he pointed toward the scene of the recent conflict.

For an instant Bud said nothing. Then, with trembling lips, which alone betrayed his feeling, he remarked:

"That was it! They divided their gang and started a fake fight up at one end, to draw us there, while they worked against our big herd at the other end. It was a slick piece of work. No wonder they shot more than they hit. They wanted to keep us away from the south of the valley."

"I guess you've struck it, Bud," said Snake, grimly. "They sure fooled us, an' I never smelled a rat! Whew!"

Bud, with lips that were firmer now, touched spurs to his pony and hastened toward the tents and corral.

"What you aimin' to do?" called Yellin' Kid after him.

"I'm going to get on the trail of those rustlers," grimly announced Bud Merkel, "and I'm not coming back until I land 'em! Come on, fellows," he called to his cousins. "Let's pack up for a long hike on the trail!"



CHAPTER XVII

WILD COUNTRY

Following after Bud, his cousins and the older cowboys swept along toward the home camp—to the tents which served the purposes of ranch buildings. Yellin' Kid trotted beside Old Billee, who, however, now that his bullet-scarred side had been bandaged, rode with more ease.

"What you goin' t' stop for?" asked Snake, when he saw Bud turning in toward the corral where spare ponies were kept. "Aren't you going after the rustlers?"

"Yes, when we get packed up for a long ride!" Bud answered grimly. "What's the good of riding over just to look at the place where they drove off our cattle? I can see that any time. What I want to do is to get on their trail."

"And not give up until we land 'em!" added Nort.

"That's talking!" cried his brother. "Did you see any of 'em, Buck Tooth?" he asked the Indian, beside whom he was riding.

"Me see too many," was the grim answer, which explained why the Zuni had probably not gone in pursuit. "They ride like what you call—jack-rabbits."

"They can't keep that pace up long," declared Bud, as he slipped from the saddle, having turned his horse into the corral. "They can start the steers off with a hip-hurrah, but they'll have to slow down if they don't want to kill 'em, and that wouldn't pay. They'd get some fresh beef and the hides, but they'd waste more than they'd get out of it."

"What do you imagine they really plan to do, and who are they?" asked Dick, as he and his brother followed Bud to their own special tent.

"I can only guess who they are, and your guess is as good as mine," the western lad answered.

"Then I'll say Del Pinzo and the Hank Fisher gang," ventured Nort.

"And I'll agree," replied Bud. "They have two motives, now, for working against us. One because we've beaten 'em in two innings— the time of the Triceratops and in the underground river game. But getting our cattle—or the cattle of any other rancher—is reward enough in itself at the price beef is selling for now. They want to make a lot of money, and ruin us because we've come to Happy Valley. But they'll find that we can bat a little, too," added Bud, carrying out the simile of a baseball game. "And it's going to be our turn at the plate mighty soon!"

"The sooner the better," declared Nort, and his brother nodded in agreement.

When Old Billee's wound had been further attended to, with the more adequate remedies kept in camp, there was a gathering of the "clan," so to speak, in the tent where the boys and their cowboy helpers usually ate.

"Then you aren't going to chase over to where they drove off your cattle right away; is that it, Bud?" asked Snake.

"I don't see any use," said the young western ranch lad. "All we'd see would be the marks of the trail, and they'll stay for some time, if it doesn't rain, which isn't likely. What I want to do is to pack enough grub—and other things," he added significantly with a motion toward his .45, "for a long trip. We've got to get at the bottom of how they drive off our cattle, and manage to get them out of the valley without leaving a trace.

"That's the puzzle we have to solve, as we found out about the hidden water. Up to now the raids of Del Pinzo and his crowd— assuming that they are the ones—have been small. They're the kind that's always going on, and a lot of the cattlemen, and Dad among 'em, seem to shut their eyes to the thefts. I'm not going to do that. But what I started to say was that, up to now, the raids have been small ones. Very likely they thought we wouldn't make much fuss over the steers we lost.

"But this is a big raid, and the others were only leading up to it. They played to get us out of the south end of the valley, and away from our big herd so they could drive it off unmolested."

"And they sure did it," added Nort.

"But they haven't gotten clear away yet!" snapped out Bud. "We're going to take after them! They can't go fast with a big bunch of cattle, and we're bound to catch them sooner or later!"

"They'll probably put up a fight," observed Old Billee, who was feeling much easier, now.

"That's what I'm counting on, and that's why I don't want any slip-up!" exclaimed Bud. "I'm going to call on Dad for some reinforcements."

"Oh, we can handle that Del Pinzo gang!" boasted Yellin' Kid.

"We could if they'd fight fair and even, maybe," assented Bud. "But they'll be on the lookout for trouble, now, and they'll have a big gang of Greasers with them. And while, ordinarily, one cowboy is a match for half a dozen of the ornery Mexicans, you've got to be on the watch for treachery. There's no use tackling this thing unless we have a big enough crowd to meet the biggest bunch Del Pinzo can muster."

"Well, there's some sense in that," admitted Snake. "I'm not afraid of any bunch of rustlers that Hank Fisher can scare up," he went on, "but it isn't a man's personal feelings we got to consider. It's for the good of this ranch. And, as Bud says, we want to make a clean-up this inning."

"That's why I'm going to have help," Bud remarked, as he went to call his father on the telephone.

Mr. Merkel whistled when he heard the disastrous news.

"I didn't think they'd go at it wholesale, that way, Bud," he told his son over the wire. "But you've got the right idea. Go after 'em and clean 'em up! When you take the trail don't turn back until you've finished the job. I'll send you as many men as I can spare, Slim Degnan with 'em!"

"Slim? That's good!" cried Bud. "Now we'll make a clean up. But don't get worried, Dad, if you don't hear from us in several days, or a couple of weeks. We'll probably be out of the reach of a telephone."

"Yes, I realize that! Well, good luck to you. When you going to start?"

"First thing in the morning. Old Billee was shot up a little, so I'll leave him and Buck Tooth to look after what cattle we have left. Can Slim and the others get here in time to start in the morning?"

"They can if I send them over in the jitney which will be quicker, and save them some hard riding. Have you got ponies enough for them?"

"Yes, plenty. Get 'em over here in the gasolene gig and we'll do the rest!" laughed Bud, though he was in anything but a laughing mood, His mind was grimly set on getting back his cattle, and in punishing the evil gang of rustlers that was dominating that section of the "cow country," as ranch localities are sometimes called.

Immediately on hanging up the receiver, Bud Merkel started in on a busy time. Nor were his cousins less engaged. Once the boy ranchers bad determined to "hit the trail," they planned to "do the trick up brown," as Nort expressed it.

Bud proved himself to be well fitted for the task in hand, in spite of his youth. But he had been well trained by his father, and life on Diamond X had put him in trim for hard fighting. It was not the first time he had had to do with cattle raids, though it was his own first experience on a large scale, and he was vitally interested. He followed the plans he had seen his father put into operation more than once.

Saddles, girths and lariats were looked to, as were all the various trappings of the ponies, without which the raid could not be undertaken in that country of far distances. Then it was necessary to pack sufficient "grub" to last for at least a week, in case no provisions could be come upon.

As for shelter, each man, and by that term I also include the boy ranchers, had a pair of blankets and a tarpaulin to spread under him on the ground. The days were hot, but the nights were cool in spite of camp fires.

Of course each one "packed a gun," some of the cowboys two, and there was no lack of ammunition.

Old Billee felt badly at not being able to go. But his wound was giving him more pain than he liked to admit, and after vainly protesting that he simply must go, he agreed that perhaps it was best for him to remain behind.

In the "jitney," as Mr. Merkel dubbed his auto, several cowboys from Diamond X (including the veteran foreman Slim) reached Happy Valley in due season. They were fitted out with ponies, and after the situation had been talked over, and every precaution against failure taken, they were ready to start early on the morning following the big raid.

The outfit of the boy ranchers had been sadly depleted by the descent of the unscrupulous gang, and what cattle remained had been driven to the feeding grounds in the vicinity of the reservoir, where Buck Tooth, Old Billee and one man from Diamond X could watch over them.

"Are we all ready?" asked Bud, as he and his cousins, followed in example by the older cowboys vaulted to saddles.

"I reckon so," announced Slim, as he slewed around his holster with its newly-oiled .45.

"Let's go!" said Bud, briefly, and away they started.

They made trail, first, to the scene of the raid. As Bud and the others had anticipated, there were plenty of signs showing where the cattle had been driven off. A large herd was missing, and it must have taken a number of rustlers to have rounded them up and started them toward Double Z, or whatever place was to be used to change, or blur the brands, so the cattle could be sold to some innocent purchaser, perhaps. Though there were not wanting, in that country, not-so-innocent-purchasers of rustled cattle.

"They'll have to keep near grass and water," said Slim, as he rode along with Bud and his cousins. "So we'll do the same."

"Yes, they can't make a dry drive very far," Bud agreed. "They followed this range, it seems."

On reaching the scene of the raid the trail led off to the left, along a tow mountain range or wild and rugged peaks, some, evidently, of volcanic origin. At the foot of this range was grass in plenty, and, occasionally, a water hole, made possible by the fact that End's father had brought the waters of the Pocut River to the valley by means of the tunnel flume.

"The trail's plain enough for a blind man to follow," said Yellin' Kid, who rode beside Snake.

"But it's going to get harder in a little while," spoke Snake. "We're getting into wilder country, and rocks don't take much of an impression. See, it's peterin' out now."

He pointed to the surface of the ground over which they were then traveling. The grass and earth were more and more scanty, and in some places there were patches of shale and rock, on which even an iron-shod hoof would leave no mark.

"Yes, it's a wild country," agreed Bud. "I've never been over as far as this, and I don't believe our cattle ever get here. There isn't enough feed," he added, as he looked around.

The cavalcade was now in a sort of narrow gorge, or gully, with rocky walls on either side, and only scant vegetation on the bottom, where some bunch grass grew. The water seemed to have disappeared.

"They can't drive cattle on a trail like this very far," said Slim, looking about with critical eyes.

"And yet they did come in this gulch," said Bud, for the "signs" were still plain.

"Oh, yes, they've been here," agreed Slim. "It sure is a queer trail they picked. I don't see—"

He did not finish the sentence. Somewhere In that lonely and wild section of Happy Valley a single shot rang out, making the echoes vibrate loudly, and awakening a distant coyote, who sent up a mournful howl.



CHAPTER XVIII

THE BOILING SPRING

"What's that?" asked Bud suddenly, his voice seeming almost as loud as that of Yellin' Kid's. The horses had been reined to a halt as soon as the shot sounded, and there was stillness which made the boy rancher's exclamation appear more vociferous than would otherwise have been the case. "What's that?" asked Bud again.

"Some one fired," answered Nort.

"Brilliant!" chuckled Dick. "Bright answer!"

"Almost as bright as my question," conceded Bud, who was willing to admit when he had "pulled a bloomer," as some Englishmen might term it. "It was a shot, though," he added. "I wonder if we'll hear any more?"

They all paused, in listening attitudes; the boy ranchers, the cowboys associated with them in the Happy Valley venture and the others sent with Slim to help run down the rustlers, on whose trail they now were.

But no further firing followed in the three or four minutes they waited there in that lonely gorge, the only sounds being those caused by the restless movements of the steeds.

"I wonder if some one shot at us, or if that was a signal!" remarked Nort, as Bud gave the sign to advance.

"I didn't hear any bullet singin' out this way," drawled Slim. "Not that I'm hankerin' to," he quickly added.

"Then it might have been a signal," went on Nort.

"What makes you say that?" Bud questioned.

"Because it would seem that if the rustlers are ahead of us, trying their best to get far enough away, or to get to some secret hiding place, that they might leave some behind, on the trail, to give warning when we show up," went on Nort.

"Yes, that might be so," slowly admitted Bud. "In fact I think it was, probably, a signal, and it may have been given by the same one who gave signals before."

"What do you mean?" asked Dick.

"I mean Four Eyes, and the lantern flashes we saw from the watch tower that night we rode in," Bud answered. "I believe Four Eyes was and still is, in with the rustlers, and that he gave a signal to show that everything was ready for the raid."

"But the raid didn't take place until some time after we saw those flashing lights," said Dick.

"It takes some time to get a cattle-rustling gang together," declared Bud. "I wish we could find Four Eyes."

His gaze roved the sides of the lonely gorge, and sought to pierce the maze of the trail ahead. But as it wound in and out, following the windings of the defile, he could not see far in that direction.

"If it was Four Eyes, he played his game mighty slick!" declared Yellin' Kid. "He fooled us all, includin' your paw, Bud!"

"Well, if we get on his trail, and can connect him with the rustlers, which it won't be hard to do, I'm thinking, he won't play any more tricks," declared the western lad vindictively and with righteous anger. "But if that was a warning shot, and that's what it seems it must have been, we'd better take some precautions ourselves."

"Such as what-like?" asked Slim, willing to let Bud take the lead, as the search for the rustlers was distinctly an affair of the boy ranchers.

"We ought not to go ahead, all in a bunch," decided Bud. "We may run into a bunch of Greasers at some turn of the trail, and if we have scouts out we can handle the situation better."

"I was going to suggest it," said Slim, "but I thought you'd think of it yourself, Bud, being as you're your paw's son."

Bud was pleased at the implied compliment, and, a little later, as they advanced, they were divided into three small parties, with rear and vanguard, to insure against a surprise in back, which might easily happen.

And so they advanced through the defile, keeping watch on both sides of the trail. There were still evidences that a herd of cattle had been driven along the rocky defile, but because of the rocky floor, if such it may be called, the signs were faint, and only an experienced westerner could have picked them up. But the boy ranchers were accompanied by experienced cow punchers, who knew every trick of the trail.

Bud had insisted that it was one of his rights to ride in the advance guard, with Yellin' Kid, and it was while they were performing this duty, of watching for a surprise, that they saw, just around the bend of the trail, some wisps of white vapor floating up.

"There they are!" exclaimed Bud in a hoarse whisper, pointing. "They've stopped there—or some of 'em have. Or maybe it's the person who fired the warning shot."

"Might be," admitted Yellin' Kid, toning his voice down somewhat to suit the occasion. "Better let me get off and crawl ahead, Bud. I'm used to that. You hold the horses."

Bud realized the sense of this proposition, and he held the reins of the Kid's horse, while that cow puncher slipped from the saddle, and, on all fours, crept toward the wall of rock which rose abruptly at a turn of the trail shutting off a view beyond.

Bud watched Yellin' Kid closely, the lad's hand on the butt of his .45, and occasionally he glanced back to catch the first glimpse of the main party, so he might warn them. He saw the wisps of vapor rising and floating toward him.

"Not much smoke," mused Bud. "They're using very dry wood— regular Indian trick. I wonder——"

A moment later he heard Yellin' Kid shout, and it was such a cry as indicated pain. Yet Bud had heard no shot.

"I wonder if they knifed him?" was the thought that flashed into Bud's brain. He cast caution to the winds and galloped forward, making a great racket, and casting loose the reins of the Kid's steed.

The sight that met Bud's eyes was enough to startle him, though it was not what he expected to see.

For he beheld Yellin' Kid standing in front of a pillar of white vapor, or, rather, the cowboy was dancing about, holding one hand in the other, and using excited slang at a rate that soon would exhaust his vocabulary, Bud thought.

But, more strange than anything else, was the fact that there was no sign of a fire, to cause the white vapor, nor was there any indication that anyone besides Yellin' Kid and Bud were in the immediate neighborhood. No rustlers had started the blaze which caused the white clouds to drift upward.

"What's the matter, Kid?" asked Bud, as he saw that something had happened. "Where's the fire?"

"Under there!" and the cowboy pointed to the ground. "Keep away from it. Don't go near that spring, an' whatever you do, don't put your hand in. I did, an' I'm sorry for it!"

"Spring! Fire! What is it, anyhow!" asked Bud, as he slid from the saddle and ran forward.

"It's a boilin' spring, that's what it is!" declared Yellin' Kid. "Boilin' hot an' it near took th' skin from my hand! What you see is steam—not smoke! Horned toads and hoop-skirts! It's as hot as Buck Tooth's tea kettle! Look out for the boilin' spring!"



CHAPTER XIX

IN A MAZE

Bud stood in amazement looking at Kid and listening to what the excited cowboy was saying. Then the gaze of the western boy rancher turned toward a depression in the ground, whence arose what he and Yellin' Kid had thought was smoke but which, in reality, was steam from a hot spring.

"A boiler, eh?" repeated Bud. "First I ever knew we had any so near Happy Valley."

"Me, either," went on Kid. "I suspicioned what it was when I got close and couldn't smell any wood burnin'. Then I put my hand out, but the steam fooled me. I didn't know the top of the water was so close, an' I dipped right down into it. Whew! It was hot!"

"Did it scald you?" asked Bud.

"Pretty nigh it," answered the cowboy, exhibiting a very red hand.

At this moment a noise behind the two attracted their attention. They turned to see pointed at them the black openings of two .45 guns, and they had glimpses of eager eyes looking over the sights of the weapons. "Don't shoot! I'll come down!" laughed Bud, in imitation of what was the current saying concerning the famous Davy Crockett.

"What is it?" asked Nort, owner of one of the menacing guns, as he arose and slid his .45 into the holster.

"Did they get away?" Dick wanted to know, as he stood beside his brother. The two boys had left the main body and worked their way up to join the vanguard, in the persons of Bud and Kid.

"There wasn't anyone to get away," Bud answered grimly. "It was only a boiling spring, and we took the steam of it for smoke."

"Boiling spring!" cried Nort. "I never saw one before."

"Me, either," added his brother, and together they looked at the depression in the ground, filled with scalding hot water. At times it bubbled up, like some great kettle over a fire, and then the steam was as thick as the smoke at some camp fire when green wood is used. Again the spring was comparatively quiet.

"I've seen 'em before," remarked Bud, "though I didn't know we had any so near Happy Valley. There's lots of 'em out in the Yellowstone Park region, and in other places, some not many miles from here."

"Any volcanoes?" asked Nort.

"Or geysers?" Dick queried.

"Not that I know of," Bud answered. "You don't need volcanoes to make boiling springs, though I suppose the hot water must be boiled over some internal fire beneath the earth's surface. And these same fires do, sometimes, make volcanoes.

"But I've never seen any volcanoes around here; have you, fellows?" and he appealed to the cowboys.

"Not since I came up from Mexico," one answered. "I was close to one there. And I've seen Old Faithful, and some of the other geysers in the Yellowstone."

"They put soap in some to make 'em spout, don't they?" asked Dick, who remembered to have read something to that effect.

"So I've heard," the cowboy said, "though it isn't supposed to be done. It sort of wears out the geyser, I believe, though I don't know much about such things. Anyhow, I don't know of any around here, though I have seen a few boiling springs, farther to the south."

"Yes, I have, too," Bud admitted. "Well, here's one, and she sure is hot," he added, as a sudden activity on the part of the phenomenon sent up another cloud of steam. "We could boil eggs there if we had any."

"We brought some along," Dick said, "but they're hard-boiled already. No use doing the job over. Say, but this is interesting!" he added, as the spring suddenly spouted up a little way, almost like a miniature geyser.

"It would be more interesting if we could get closer on the trail of that gang of cattle thieves, and take away our steers," said Bud. "I wonder if the poor animals hurried in here for water, and couldn't drink it because it was hot?" He recalled days of helping haze cattle on long trails, when the creatures were tormented by thirst, and he knew how they suffered.

"There are a few signs that they've been in here," remarked Slim, as the party was gathered around the boiling spring. "But they aren't here now."

"Not much use in us staying here, either," commented Bud, as he looked around on the bleak and cheerless prospect. Except for the boiling spring there was no sign of natural life. All about were great and small rocks, piles of shale and jagged stones, as though the place had been swept by a prehistoric fire. They were in one of the twists and turns of the rocky defile, and it was a rocky pass, with no trees or grass growing except near the top, and these appeared to be a sort of overgrowth from the grass and foliage growing down above.

"No, they didn't stop here long," declared Yellin' Kid. "They passed on, an' that's what we got to do."

"Might as well stay here and have grub, now we're dismounted," suggested Nort.

The idea was voted a good one, and was soon put into operation. They ate and talked of what had passed and what lay before them. Of the latter they could only conjecture, but it is safe to say that not one of them in his wildest imagination ever conjectured such an ending to their trailing as actually occurred.

"Well, let's get on," called Bud, when appetites had been satisfied—that is all but those of the horses. There was no grass for them, though they did manage to drink some of the water from the boiling spring where it had collected in little pools, and had cooled. But this would never have sufficed for hundreds of cattle.

Once more they were on the way, and shortly afterward they left the grim and rocky defile for a more fertile region, where there was grass for the animals. But they were still down between a range of high hills which towered on either side.

The trail twisted and turned, this way and that, winding back and forth. But ever there was to be seen, here and there, signs that the herd of cattle had been driven this way. Faint the signs were, at times, and at last they disappeared altogether.

"Where have they gone?" asked Nort.

"Looks like they dropped down a hole, but there isn't any hole here," said Yellin' Kid.

"Oh, we'll pick the trail up later on," suggested Bud.

But even as they started off once more Bud, who had just consulted a compass he carried, uttered a cry of amazement.

"What's the matter?" asked Slim.

"We're going the wrong way," declared Bud. "We're heading north instead of south. We're all turned around! Something's wrong!"



CHAPTER XX

A SURPRISE

Some of those in the rear, who had heard Bud's exclamation, but who had not clearly heard what he said, came crowding up. Among them was Snake Purdee, and his eyes sparkled with hidden emotion as he inquired:

"Did you see any rattlers? This is just the place for 'em!"

"Yes, we came acrost a nest of baby ones what had lost their mother, an' they're countin' on you t' bring 'em up on th' bottle!" laughed Slim. The men, more or less, poked fun at Snake because of his great fear of reptiles, and Slim could not forego this chance.

But Snake understood the game, and realized that he had nothing to fear. He shot a look at Slim, however, which indicated that there would be an attempt, later, to get even.

"What's wrong?" asked Slim, for in his endeavor to play a joke on Snake he had not paid much attention to what Bud was saying.

"We're all turned around," spoke the western lad. "All in a maze. We started out, heading south, and we've kept, generally, to that direction ever since. But now we're heading back north. Looks like we'd lost the trail."

Slim and some of the more experienced cowboys studied the trail for several minutes. Surely it did seem to "peter out," as Yellin' Kid expressed it, though it had been fairly plain up to this point.

"They couldn't get up on either side," declared Nort, looking at the steep, rocky walls which hemmed the trailers in right and left.

"And they haven't gone on ahead, for there isn't a sign," added Dick, who had ridden up the defile for some little distance, returning to make his report. "Nothing short of an air ship could have lifted up a bunch of cattle from this gorge and set 'em down farther on."

"Unless they went through a hole in one of the side walls," suggested Slim, "like that underground river you fellows discovered in the tunnel."

"There are no side passages here," declared Bud. And he seemed to hold the correct view of it, the others agreeing, after a careful inspection of the rocky and shale-covered walls on either hand. "It looks just as if they came up to this point and—vanished!"

"Pretty slick work—I'll give Del Pinzo credit for that," said Slim, as if it were already established that the wily Greaser halfbreed had made the descent on Happy Valley. "How he and his bunch could haze cattle this far into a rocky pass, an' then make 'em disappear, gets me!"

"It shore do!" shouted Yellin' Kid.

"But that doesn't change the fact that we're all switched around," declared Bud. "We're going north instead of south!"

"Not so hard to account for that," said Snake. "This vale just naturally twists and turns like a windin' river. I wouldn't wonder but what we'd been going north other times, only you never noticed your compass, Bud."

"Well, maybe so," admitted the boy rancher, rather dubiously. "But it looks as if we were back-trailing, instead of keeping on after those rascals."

"We're keeping on all right!" asserted Slim. "By some hook or crook they've fooled us, but we haven't passed 'em, that's certain, and they must be somewhere up ahead. It would take Rocky Mountain goats to scramble up there," he added, motioning toward the steep walls of the gorge. "Some trick ponies might do it, but no cattle ever could, unless they're like some of them Swiss cheese brand I seen in pictures!"

"Then do you think we should keep on?" asked Dick.

"I shore do!" declared the foreman.

"Forward march!" cried Bud, with a little laugh. "We want to get our cattle back, and catch the rustlers who took 'em!"

And so, though all signs of the trail seemed to have vanished, they kept on. Night saw them in even a wilder region, though there was a spring of water—not boiling this time—and some grass for the animals. So it was decided to camp there and take up the search in the morning.

They were in the enemy's country in every sense of the word, and could afford to take no chances. So after a fire had been built, and coffee made, bacon and flapjacks being the other items on the bill of fare, the men and boys were told off into watches.

Bud and Slim, Nort and Snake, and Dick and Yellin' Kid were assigned to divide the night among them working as partners in the order named. The others were to be allowed to roll up and get what sleep they could, Bud and Slim taking the first watch.

That passed off uneventfully, as did the vigil of Nort and Snake, nothing more important occurring than the distant howls of the coyotes.

When it was the turn of Dick and Yellin' Kid they rolled out, albeit sleepy and tired, to stand guard until morning, when the trail would again be taken up.

"Zimmy! But it's chilly!" said Kid in a low voice, as lie tossed some wood on the fire and wrapped his blanket more closely about him.

"Yes, it always is just before sunrise," added Dick. "I wonder what we'll find after daylight?"

"I hope we find that ornery bunch!" murmured Yellin' Kid, keeping down his voice so as not to awaken the sleepers.

"So do I," said Dick.

Then they sat about the fire, occasionally strolling around the improvised camp, to make sure that none of their enemies were creeping up on them in the darkness.

The stars shone clear and bright in the sky above, and occasionally a little wind swept up the dismal defile. Now and then a loose stone rattled down the sides of shale and volcanic rock, and at such times Dick, and even Yellin' Kid started, and felt for their guns. But all the alarms were false ones.

That is, the watchers decided they were, for no sight was had of anyone until Dick, after a stroll about the fire, suddenly started back and whispered to Yellin' Kid:

"Isn't that a head looking up over that rock?"

The Kid glanced to where Dick directed his gaze, and, in an instant, the cowboy had his weapon out and leveled. His finger was even pressing the trigger when he laughed silently and thrust the .45 back in its leather case. "Why didn't you shoot?" asked Dick.

"It was an owl," answered Kid. "It was his ears you seen stickin' up! Listen!"

And, a moment later, there was the mournful hooting of the nocturnal bird, which had flown away, but on such downy-feathered wings that it made no sound.

"An owl!" murmured Dick. Then he was glad he had not shot first, as he had intended. He would only have awakened the others and been laughed at for his pains. Sometimes, he reflected, it was better to hold your fire, even in the west, that region of quick action.

Soon there was a little grayish, pinkish light to be observed over the edge of the eastern hill. It grew slowly, and daylight came, though it was some time before the sun itself was seen, so deep were the searchers down in the defile.

After breakfast they set out again, looking carefully for signs of the rustlers, but they saw none, and at last they decided that, in some mysterious manner, their quarry had given them the slip.

"Though I don't see how they did it," declared Slim, somewhat vexed that he and his men were not better able to pick up the trail.

"There must be some side passage—like that!" suddenly declared Yellin' Kid, leaping from his horse and then, as suddenly disappearing from the sight of his companions. "Hey! What's the idea! Where'd he go?" asked Snake.

"In this side passage," answered Yellin' Kid, as suddenly reappearing. "Look, here's a crack, or fissure in the rock, I saw it from where I sat on my pony. It goes off from th' main trail, but I can't see where it leads."

They all dismounted and investigated. As the Kid had said, it was a traverse defile, opening out of the main one and almost at right angles. The opening was concealed behind a great pinnacle of rock, so that the cleft was only visible from a certain point, and it was at this point that the Kid saw it.

"Where does it go to?" asked Bud as they entered, single file. It was only wide enough for that.

"We've got to follow and see!" said Slim.

"If there was a place like that, back where we discovered we were in a maze, it would have been easy enough for the rustlers to have driven the cattle through, one at a time," observed Nort.

"But there wasn't any such place!" declared Bud. "We made sure of that. But where does this lead?"

That was what they all conjectured, and they were soon to learn. As they rode along, the side cleft widened, until there was room enough for three to ride abreast. And it was while thus progressing that Dick, who was in the lead with Slim and Snake, made a surprising discovery. He rode around a turn in the new trail, and at the sight of something beyond, in the smaller, rocky defile, he set up such a shout as brought all his companions to his side.

"What is it?" shouted Bud.

"Look!" answered Dick, pointing. "Del Pinzo and big gang!"



CHAPTER XXI

IN PURSUIT

Two deep-throated shouts echoed amid the winding mazes of the small canyon leading off from the main gulch that the boy ranchers and their friends had been following. One shout followed closely on that of Dick, announcing his amazing discovery. The other came from the band of rascals whose hiding place had at last been spied out, and by a mere chance at that.

One shout was that of joyful anticipation, and this came from Bud, Dick, Nort and the friends from Diamond X. This shout had in it an anticipation of righteous punishment to be inflicted on those who had stolen the cattle.

The other shout was of baffled rage that their hiding place had been discovered. This shout came from Del Pinzo and his gang.

For it was the lawless Mexican half-breed and his followers, numbering in all more than two score, whom Dick had seen as he made the turn in that winding and narrow gorge. At a place where the rocky defile flared out, making a sort of amphitheatre there were gathered about a spring of water, their horses tethered where they could crop the scanty herbage, the crowd of which our friends had long been in pursuit.

Following the two shouts—one of pleased discovery and the other of baffled rage at being discovered—there was quick action.

"Here they are!" shouted Bud, as soon as he had joined Dick, and had seen what the latter had fairly stumbled upon. "Here's the Del Pinzo crowd!"

Up came riding Nort, Slim, Snake and the others.

"Oh, boy! We've got 'em just where we want 'em," was the exclamation of Yellin' Kid. And I leave you to judge in what tone he uttered the words.

"Unlimber, boys!" called Slim Degnan, grimly and significantly as he whipped out his .45. "There's likely to be action!"

"Hold on! Wait a minute!" counseled Snake, as Bud and his cousins were about to urge their horses forward. The cowboy reached out, and his hand fell with a firm grip on the bridle of Bud's steed.

"What's the idea?" asked that boy rancher. "Now we've found the rascals, can't we go in and clean 'em up?"

"That's natural Bud, most natural," conceded Snake. "But what's th' use runnin' your head in a bee's nest if yon can git th' honey some other way?"

"You mean it won't be safe to ride up to 'em and fight 'em?'?" asked Nort.

"Somethin' like that, yes, son," answered the cowboy. "I think Del Pinzo an' his crowd have been waitin' for just such a chance as this. They'd ask nothin' better than t' have us rush 'em, an' then they'd have a good excuse for sayin', afterward, that they popped us off in self-defense."

"Snake's right!" declared Yellin' Kid, modulating his voice somewhat. "We'd better play this hand cautious like."

Seeing that this was the sentiment of the more experienced men, Bud and his cousins held back, and a moment later, urged by the cowboys, the ranch lads had turned aside and the whole body of pursuers had retreated to a position somewhat away from the turn of the trail where Dick had looked through the defile and had seen the rascals encamped.

"What's the next move?" asked Nort, as the party gathered together, giving their horses a breathing spell, for which the animals were, doubtless, very thankful.

"We'd better look for some shelter," advised Snake, "an' then see what we can do toward learnin' th' intentions of this bunch of bad actors."

"You mean sort of spy 'em out?" asked Dick.

"That's it," chimed in Yellin' Kid. "If this is goin' to be a fight, an' it shore looks as if there was, we want to take all th' advantage we can. They outnumber us two to one!"

This was true enough. The fleeting glimpse our friends had of the outlaws, through the crack in the rocky wall, showed that there were more than two score under the leadership of the unscrupulous Del Pinzo.

Following the skilful advice of the cowboys, Bud and his cousins took their places behind some sheltering rocks, leading their horses in with them, for much depended on their mounts. Without them it meant giving up the chase. And even if one pony was killed or wounded, it meant that its owner would have to make his way back on foot, which was neither pleasant nor safe.

"Get your guns ready," said Slim. "There's going to be action, but not just yet. We want this to be a winnin' fight if we can make it so."

Once within comparative shelter, and feeling somewhat calmer after the first wild excitement, Bud, Nort and Dick looked to their older companions for further advice.

"Somebody's got t' go back t' that crack, unbeknownst t' them scoundrels, an' see what they're doin'," decided Slim.

"S'pose they're there yet?" asked Bud.

"Either that, or they've taken the alarm an' are on their way, or they're doin' just what we are—gittin' ready for a fight," said the foreman grimly. "An' what it is they're doin' we want t' know. Snake, you're pretty good at Indian tactics. S'pose you sneak up there an' take a look in."

"All right," was the ready answer.

Of course Bud, Nort and Dick, each and every one of them, wished they had been selected for this duty. But while they were rapidly learning the ways of the west, in dealing with desperate characters, it was better at this time to have an experienced man spy out the movements of Del Pinzo and his gang. This Snake set out to do.

"An' while he's gone, th' rest of us want t' sort of make up our minds what t' do," said Slim. "If that bunch is gettin' ready t'rush us, same as we may be able to do on our own hook, we want t' have some plan of action."

So a sort of council of war was held, during the absence of Snake, who was soon lost to sight among the rocks, the cowboy making his way in a crouching, crawling position that almost resembled the reptiles he so feared and hated.

There was some low-voiced talk among the remaining cowboys, in which talk Bud and his cousins had no part. For a moment the lads feared there was some scheme afoot to put them in places of safety, out of danger so to speak. And the boy ranchers weren't going tamely to submit to this.

"I say, Slim," exclaimed Bud, with this fear in mind, "we are going to do our share in this fighting, you know!"

"Shore I know it!" grunted the foreman. "You'll have all th' scrappin' you want, if these fellows don't vamoose without firin' a shot! We was just talkin' of the best place t' put you."

"Oh," murmured Bud, "all right."

After some little talk, and a survey of the ground to which the pursuers had retreated in order to make a temporary stand, each person's position was designated, and then guns were loosed in holsters and the supply of cartridges was looked to.

"As soon as Snake comes back we'll know what t' do," Slim said.

"He ought to be along soon now," remarked Dick.

Hardly had he spoken than there was a noise among the loose rocks and boulders some distance up the gulch—in the direction the spying-out cowboy had taken.

"Here he comes!" exclaimed Bud, and his hand went to his gun, for it was very possible that Snake would be pursued, and have to retreat on the run.

However the alarm proved to be a false one, for, after waiting some time, Snake not having appeared, it was surmised that some rock had become loose and rolled down the steep side of the gulch.

The waiters and watchers were just beginning to get a bit worried, and Bud was on the point of suggesting that he be allowed to go look for Snake, when the cowboy came back.

So quietly did he approach, and so unexpected was his appearance that Nort and Dick, on whose side of the improvised "fort" Snake first showed himself, were startled.

"If that had been any of the Del Pinzo crowd they'd have been on top of us before we knew it," confessed Nort.

"Not much!" laughed Bud. "Slim has seen Snake coming along this last three minutes; haven't you, Slim?"

"Yep! I noticed him, but I didn't say anythin'," acknowledged the foreman. "I seen that he was alone. But what's the verdict, Snake?" he asked, anxiously. "Are they gittin' ready t' come at us here, or are they leavin'?"

"Neither one," was the answer, "but they're gettin' ready to do suthin! They're all in a bunch in the middle of that place, holdin' a confab, I reckon. It's hard to say what they are up to. But I got a hunch that if we rushed 'em we could throw a scare int' 'em, anyhow."

"Do you think they know we're here?" asked Bud.

"Oh, sure!" was the answer. "At least they saw us an' heard us when we reached that crack. But of course they can only guess what we're up to now, when we didn't rush 'em first shot. They might have known, though, what our plans was, if I hadn't cracked their spy on the head!" said Snake, calmly.

"You did what?" asked Slim.

"Just as I got t' th' place where I could look in," went on the cowboy, "I saw one of them Greasers up t' the same trick I was tryin' to pull off. He was sneakin' down this way, but I saw him first. Caught a glimpse of his head around the edge of a rock; I just reached out with my gun and tapped him on the noodle."

"Kill him?" asked Dick.

"No. Guess not. Just stretched him out so he can't go back an' tell any tales for a time. Now the way I figger it is this: They'll be waitin' for a report on what their spy sees, same as you was waitin' for me t' come back. Only their spy won't show up for a couple o' hours, an' that gives us a chance to act."

"What had we better do?" asked Yellin' Kid.

"Rush 'em!" instantly decided Snake. "Let's git t' that openin' as quiet as we can, an' rush right for 'em! This rest has freshened our horses, an' we're in better shape now."

"Not so much so, as far as horses go," dubiously declared Slim. "They're pretty badly spent, and can't do much racin'. But I guess maybe it is better for us t' get into action, instid of waitin' for that bunch t' come here. As Snake says, they'll be lookin' for their spy t' come back, an' maybe we can take 'em unawares."

So, after some further talk, it was decided to mount again, ride to the opening that led from the main trail into the hiding place of the outlaws, and boldly attack them.

True, our friends were outnumbered, but they had right on their side, and this sometimes makes a difference. Also they would have a little advantage, they hoped, in making the attack somewhat unexpectedly. For though Del Pinzo and his crowd knew the ranchmen were in the neighborhood they would, as Snake believed, await the return of the spy they had sent out, before doing anything.

"An' that spy won't come t' his senses very soon," declared the avenging cowboy. "When he does he'll have an awful headache!"

As quietly as possible they made their way to the opening. Slim, as a sort of captain, was in advance of the others and looked in. He came back to say:

"They're gettin' ready for suthin'! They're all standin' near their horses, an' seem to be plannin' a move. Get ready t' rush in when I give the word!"

There was a final look to arms and saddle leathers, and then the foreman cried:

"Get into action!" at the same time spurring forward his pony, an example followed by all the others as they rushed into the defile.

And action there was, but not exactly of the kind the boy ranchers and their friends anticipated. For Del Pinzo (easily recognized among the lesser lights of rascaldom) with his followers, after their first angry shouts, leaped for their horses. And their agility in that respect spoke well for their preparedness. In an instant, it seemed, every one of the two score, and more, was in saddle, and headed out of the defile. They were retreating—riding away from the following avengers, and going, it seemed, further into the maze of winding clefts amid the mountains.

To the credit of Del Pinzo—if credit it be and if he be entitled to get credit—he rode at the rear, not starting his horse until all his men had raced away ahead of him.

And then, as Bud, Dick and the others pressed into the defile after them, the Greaser turned and fired once, but with such quick action that eye could scarce follow the motion of his hand and weapon.

There was a sharp crack and the hat of Yellin' Kid, who rode immediately behind Bud, sailed off his head, at the same time that a bullet zipped viciously over the pursuers.

"Close call that, Kid!" remarked Snake, leaning over as his horse galloped forward, and picking up his friend's hat.

"Close nothin'!" snapped out Yellin' Kid. "That was fancy shootin'! If Del Pinzo wanted to get me he could 'a' done it. He can mark out th' pips on a ten spot card with his eyes shut, almost! He shot my hat off just to show he wasn't aimin' t' spill no innocent blood! But wait until I get him! I'll make him sweat for that! A hole through brim an' crown! Why couldn't he be decent about it an' make it one?" grumbled Yellin' Kid as Snake handed him the hat.

"Never mind that!" shouted Slim Degnan. "If we're going t' get them fellers we got t' ride!"

That was evident, for even as he spoke Del Pinzo, the last of the outlaws, disappeared around a turn in the defile. He was "hazing" his men along to some other hiding place, it appeared. And he and his rascally followers seemed to know their ground, for they rode at break-neck pace, without fear of what lay beyond and unseen. It is likely they had traveled that route before.

Another advantage lay with the rustlers. Their horses were fresh, for from the negligent attitudes assumed by the men when Dick had discovered them, it was evident they had been at ease for some time, whereas the pursuers had been on the trail a long time, and the way had been rough and stony.

So it is nothing to the discredit of the boy ranchers that they and their friends were distanced in the first wild rush following the discovery and alarm.

"Come on!" cried Bud. "Come on!" and he and Dick for the moment were in the lead, the canyon being wide enough, here, for several to ride abreast. "We've got to get 'em!"

"And we won't stop until we do!" added his cousin.

But they reckoned not with the roughness of the way, the start the rustlers had, their fresher horses and the fact that Del Pinzo and his crowd were more familiar with the trail than were the boy ranchers. So though our heroes rode on as fast as they could go with comparative safety, they did not, for some time at least, again come within sight of the enemy.

"Wait there! Hold on a little!" finally called Slim to Bud, Dick and Nort, who, in their youthful and natural eagerness, had forged to the front in a bunch. "Pull up! This isn't a hundred yard dash! It's going to be a long race!"

Bud was beginning to believe this, and some of his first exuberance was disappearing. He was getting more cool-headed.

"Let's take it a bit easy," he said to Nort and Dick. "I guess we've got a long trail to follow."

"But we've got to get 'em!" declared Dick.

"You got rid of something that time!" commented his brother, meaningly, if slangily. "We're going to make 'em give back our cattle!"

"Say!" suddenly cried Bud. "That's the queer part of it! Where are the steers?"

And for the first time it occurred to the minds of the boy ranchers that of that quarry they had come most in search of they had had not a glimpse. Not a steer was in sight!

Something of the amazement they felt must have been depicted on their faces, for when Slim rode up to where the boy ranchers had halted he asked:

"What's the matter?"

"Where are the cattle?" asked Bud, shouting almost as loudly as Yellin' Kid would have done. "Did you notice they didn't have a one with them, Slim?"

"Yes. Are you just waking up to that, Bud?"

"I reckon I am. But what does it mean?"

"It means that there's a deeper game being played than we have any idea of, son. We've got to go some to get to the bottom!"



CHAPTER XXII

BUD'S DISCOVERY

Once it became evident that catching the rustlers was likely to be the work of a long chase on the trail, the whole party of pursuers came to a halt beside the boy ranchers. And after some rapid talk of what might lay beyond their stopping place, in a lonely, wild and desolate section of the defile, the conversation switched to what had surprised Bud and his cousins—the absence of the cattle.

"I s'posed they were driving the steers ahead of 'em all along," admitted North "They drove the animals off our ranch, and I didn't think but what they were hazing 'em along to some place where they could change or blur the brands, and then sell 'em."

"That's what I thought, too," acknowledged Dick.

"Well, I must say I didn't think much about it," confessed Bud. "When I saw Del Pinzo and his gang in there all I wanted to do was to come to hand-grips with 'em. I forgot all about the cattle. But after we'd chased along a bit I did begin to wonder where my animals were—our animals, I should say," he corrected himself with a glance at his cousins. However, they understood.

"They must have gotten the cattle over to Double Z, or wherever it is they dispose of 'em," suggested Dick.

"They couldn't—not in this short time," declared Slim. "We followed 'em too close. Besides, there isn't a sign of any cattle having been here, nor in that place where we surprised th' head Greaser and his gang. Not a sign of cattle!"

He looked up and down the gorge, as did the other cowboys. But not even the sharpest eye could detect the faintest "sign" of the steers having been driven along the passage.

"They must have them hidden somewhere," said Dick. "We'd better go back to the place where the sign petered out. There must be some opening there out of the main canyon."

"If there is it's so well hid that it takes sharper eyes than I've got to find it," declared Snake, and he was noted for his far-seeing and clear vision.

"Go back!" exclaimed North impulsively. "We aren't going back, are we, until we get Del Pinzo and his gang?"

"Shoot 'em up—that's what I advise!" cried Yellin' Kid. There was a moment's pause, and Bud spoke.

"We're got two things to do," said the boy rancher. "One is to get our cattle back, and the other is to nab the rustlers. But it's more important to get the cattle, I think.

"If we don't do that our ranch experiment will be a failure," he went on. "But, of course, for the sake of other ranchers, it would be a mighty good thing if we could put Del Pinzo and his rustler crowd out of business."

"Can't we do both?" asked Nort.

"That's what I was coming to," his cousin continued. "If we can get on the trail of the hidden steers—for hidden they are, I'm sure—we can haze them back to the valley. Then we can keep on after this crowd," and he nodded toward the winding trail that led down the narrow defile.

"Then you think we'd better go back!" asked Dick.

"Let's see what Slim says" answered Bud. Naturally he would turn to his father's foreman for advice.

"Oh, you're leavin' it t' me, are you?" asked Slim, as he finished rolling his cigarette, a feat he could accomplish with one hand. Then he lighted it, took a satisfying puff and went on: "If you ask my advice I'd say to go back an' see if you can't locate the cattle. As Bud remarks, they're dollars an' cents. Th' rustlers aren't, though it would be a mighty good stunt t' wipe 'em off th' face of this cow country. But maybe we can attend to them later."

"Turn back she is!" exclaimed Bud, accepting, as did the others, the advice of Slim as being final. "We'll see if we can find the cattle, and then haze them to a safe place. After that we'll nab Del Pinzo and his bunch—if we can," he added, as a saving clause.

"Suits me!" remarked Yellin' Kid, taking off his hat and looking at the two bullet holes. "That nabbin' part is what I want t' play at," and his grin suggested that when he and the Greaser met there would be some interesting happenings.

It having been thus decided that the pursuit would be abandoned for the time being, a sort of council of war was held to settle on the next course.

"I say grub!" exclaimed Bud, knowing that the suggestion would come with better grace from him than from some of the men who were working for him and his father. "Let's eat!"

There was no debate on this question and when the ponies had been turned loose to graze on what scanty grass they could find, a fire was made and preparations started for feeding the hungry posse. For they were that—both hungry and a posse, bent on the capture of the lawless rustlers. Though, for the time, righteous revenge was given over to the more practical side of the question—getting back the cattle.

Probably you do not need to be told that little time was wasted over the meal, simple as it was. Cowboys, on the trail, or otherwise engaged in their work of the ranch or range, do not spend much time over the pleasures of the appetite. There is a time for feasting, and a time for chasing cattle rustlers, and there was no sense in combining the two. That, evidently, was the thought in the minds of Bud and his friends, for they hurried through their eating, and, having rested the horses, were soon in saddles again.

"Now," remarked Bud, talking the matter over with Slim, "what is the best plan?"

"To get back, as fast as we can, t' th' place where we saw th' last signs of th' cattle," was the foreman's answer. "The unravelin' of th' skein of mystery, t' use a poetical expression, Bud, is there!"

They all agreed with this view of it, and after a short ride down the defile, to see, if by chance, any of the Del Pinzo crowd might be in evidence, or returning, the back trail was taken.

"We aren't going to discover much this day," observed Bud, as he rode slowly along between Nort and Dick.

"Why, did you see a black rabbit?" Nort asked, remembering what had happened when a similar incident occurred, just before the strange events narrated in the chapter preceding this.

"No, I didn't see a black jack," Bud answered. "But it won't be long until dark, for we don't get the full benefit of the afternoon sun down in this gorge. And we can't do anything except by daylight. No use looking for sign in the dark."

"That's right," agreed Nort. "But I was afraid it was a black rabbit you'd seen."

"As if we didn't have enough bad luck without that," commented Dick. "It's as bad, losing your herd as it is not to have enough water to give 'em what they need," and he referred to the time when, by the efforts of this same Del Pinzo, the supply for the reservoir of Happy Valley was cut off.

"Oh, well, it might be worse," observed Bud, with a sort of cheerful, philosophical air, for he was of rather a happy disposition.

"How?" asked Snake, for he was rather "sore" because Del Pinzo and the rustlers had escaped. Perhaps Snake felt that he might have gone in and captured the outlaws single-handed when he was on the lone spying expedition.

"Well, I might never have had any cattle for those fellows to steal," went on Bud. "But say, boys," he went on, as they came to a place where the trail seemed to divide. "Let's take this other road back. It looks a bit easier, and we want to favor the ponies all we can."

"Go ahead," advised Slim, to whom Bud looked for confirmation of his plan. "Anything that makes it easier for th' horses makes it more sure for us. And we may have a long hunt ahead of us."

The care taken by the boy ranchers and their friends of their animals was not exaggerated, nor unusual. In the West so much depends on a man's horse—his comfort and very life, often—that it is a foolish fellow, indeed, who will not bestow at least some thought and care on his horse. The animal becomes a trusted companion and friend to the cowboys and prospectors.

So, in order, as he hoped, to provide an easier means of getting back to the place they wished to reach, Bud led the way along a different trail on the retreat.

It was practically a retreat, though one they had selected for themselves, since the outlaws had distanced them.

It was rather a dejected bunch of boy ranchers and their friends that were now back-trailing. There was not much talk, after the excitement of the attack which had "petered out," and even Bud, gay and cheerful as he usually was, now seemed to have little to say.

It was Dick who startled them all by suddenly exclaiming:

"Look ahead there! Isn't that a man on the trail?" He, with Nort and Bud were in advance of the others. Dick pointed toward the place where he thought he saw something suspicious.

"I don't glimpse anything," observed Nort.

"Nor I," said his cousin.

"He's gone now," Dick stated. "But I did see some one, and I'm almost sure it was a Greaser. Looked just like one of their hats."

"What is it!" called Slim, for he caught snatches of the rather excited talk of the boys.

"Dick thought he saw one of the Del Pinzo gang," answered Bud.

"Maybe he's the fellow I cracked on the head," suggested Snake. For they had lost sight of that individual in the mad rush into the canyon, and had not seen him when they turned back.

"Say, wouldn't it be a good thing to capture him?" asked Bud eagerly. "We could make him tell where the others are, and where our cattle are hidden."

"If we can get him," conceded Slim.

"There he is again!" cried Dick. "Come on, fellows!"

Disregarding, or forgetting the travel-weary horses, the ranch lad urged his own steed ahead at as rapid a pace as the animal could be induced to develop in a spurt.

"Take it easy!" advised Nort to his brother, but he might as well have called to the wind, for Dick was off and away.

"I don't see anything!" cried Bud, and though he had looked eagerly forward at Dick's call he had glimpsed neither hat nor face of any personage who might be suspected of being one of the Del Pinzo gang.

But, even with that, Bud was not going to miss a chance to be in at the finish of whatever was about to happen, so he spurred his animal forward.
