+A MYSTERIOUS DISAPPEARANCE

+
+<P>
+"Look out there, Bud! Look out! There you go!"
+</P>
+
+<P>
+"Side-stepping soap dishes! What's the idea? Whoa, there, Sock!"
+</P>
+
+<P>
+The pinto pony reared, swerved sharply to one side as a black streak
+shot across the trail almost under his feet and then, when the animal
+came to a sudden stop, there shot over his head the boy who had given
+vent to the last exclamation.
+</P>
+
+<P>
+Bud Merkel came down sprawling on all fours in a bunch of grass which
+served, in a great measure, to break the force of the catapult over his
+pony's head. And then, as the lad righted himself and limped over to
+catch his steed, he cried:
+</P>
+
+<P>
+"What in the name of the petrified prune pie was that, Billee?"
+</P>
+
+<P>
+"A jack, Bud! A jack rabbit, and as black as gunpowder! Yo' shore are
+in for some bad luck, now!"
+</P>
+
+<P>
+"Bad luck! I should say so! Almost breaking my neck, and laming
+Sock," and the lad looked anxiously at his pinto, being relieved to
+find, however, that the animal had suffered no harm.
+</P>
+
+<P>
+"But this won't be all!" declared Billee Dobb. "I never see a black
+jack shoot in front of a man yet that bad luck didn't follow!"
+</P>
+
+<P>
+"Well, let's make it go some to catch us!" suggested Bud as he leaped
+to the saddle, after making sure that the girths were tight. "Black
+jack! First one I ever saw," and he looked off in the distance toward
+a streak of dust, which was all that now represented the frightened
+rabbit that had shot across the trail so unexpectedly.
+</P>
+
+<P>
+"They aren't plentiful; thank your stars!" exclaimed the old cowboy.
+"I'm glad it didn't happen to <I>me</I>."
+</P>
+
+<P>
+"Yes, if you'd a' toppled over your critter's head there'd be a bigger
+crack in the ground!" laughed Bud, as he looked at his companion's
+greater girth and weight. "It came as sudden as a flash of lightning,
+that jack!"
+</P>
+
+<P>
+"Bad luck allers does come that-a-way," croaked Old Billee Dobb.
+</P>
+
+<P>
+"Oh, you and your bad luck!" laughed Bud. "Come on now, hump yourself!
+Hump yourself, you old soap-footing specimen of a slab of saltpeter!"
+he cried to his pony. "Mosey along!"
+</P>
+
+<P>
+"What's your rush, Bud? Anybody's take a notion t' think you was in
+suthin' of a hurry, t' hear you talkin' that-a-way t' your critter,"
+remarked Billee as he ambled along behind his more impetuous companion.
+</P>
+
+<P>
+"Hurry, Billee? Of course I'm in a hurry!" admitted Bud, a tall,
+well-tanned lad as he adjusted himself to his saddle, and dashed ahead
+of his companion on the dusty trail. "I reckon you'd be in a rush,
+too, if your cousins that you hadn't seen since last fall were coming
+to camp all summer with you!" and Bud Merkel swung around in his
+creaking saddle to note the pace of his companion.
+</P>
+
+<P>
+"Them two tenderfeet comin' out to Diamond X ag'in?" asked Old Billee
+Dobb.
+</P>
+
+<P>
+"Course they are!" answered Bud. "But they're a long shot from being
+tenderfeet, now, since they helped get rid of Del Pinzo and his
+cattle-rustling gang, and did their share in solving the mystery of the
+Triceratops. Tenderfeet! Guess you'd better not let 'em <I>hear</I> you
+call 'em that!"
+</P>
+
+<P>
+"Mebby not, son! Mebby not!" agreed Old Billee, rather mildly as he
+tried to urge his slower-going animal to keep pace with Bud's. For the
+pinto, responding to the spur of voice and heel, had shot ahead. "I
+sorter forgot your cousins did have a hand in the lively doin's at
+Diamond X last season. So they're coming out again, be they?"
+</P>
+
+<P>
+"Yes, and we're going to make a camp of it, over in Flume Valley. I'm
+going to raise there the finest bunch of steers you ever hazed to the
+stock yards, and Nort and Dick are going to help me. I'm riding to
+meet them now at the water-hole, and we're going back to stay all
+summer in Flume Valley."
+</P>
+
+<P>
+"Hum! Flume Valley!" mused the older cowboy, for both riders were of
+that class, though Bud Merkel was the son of the man who owned Diamond
+X, and other important western ranches. "Flume Valley! That's where
+your paw started that irrigation scheme; ain't it?"
+</P>
+
+<P>
+"Yes," replied Bud. "It was only a waste bit of land before dad ran
+the water through the tunnel-flume from Pocut River, but now it grows
+the best grass you ever rolled your bed in. And the steers&mdash;you ought
+to see 'em, Billee!"
+</P>
+
+<P>
+"Well, I'm aimin' to, right soon," responded the old man. "Your paw
+was sayin' suthin' about putting me over there, but I didn't pay much
+attention to it. So you and the eastern lads are going to camp in
+Flume Valley, be you?"
+</P>
+
+<P>
+"Yes, because, being an experiment, dad didn't want to build any ranch
+houses there yet. But if we make good on the deal, and can raise
+steers on the grass that's grown since the water was let in, why, I'm
+to have it for my own ranch, when I come of age, and Dick and Nort will
+be my partners. We'll call it Diamond X Second."
+</P>
+
+<P>
+"Good name! Mighty good name! Look out there, you old piece of bacon
+fat!" he called sharply to his animal, pulling the pony quickly up as
+it stumbled. "There aren't any prairie dog holes here for you t' go
+puttin' your foot in! What's the matter of yo'?"
+</P>
+
+<P>
+But though Old Billee and Bud spoke thus in seeming harshness to their
+horses, there was no unkindness in their treatment of the animals. It
+was just their picturesque, western manner of talking, and hardly had
+the echo of Old Billee's words died away on the hot, dusty air than he
+was gently patting the neck of the pony he rode.
+</P>
+
+<P>
+"Did dad say you were to help me over in Flume Valley?" asked Bud, as
+he slowed down the pace of his animal to keep alongside that of the
+older cowboy.
+</P>
+
+<P>
+"Yes, he said I was to be your helper. And first I sorter hated to
+leave Babe, Slim, Snake and the rest of the bunch. But if you say your
+cousins are coming out, and if we can raise better cattle there than on
+the home ranch, why, mebby it won't be so worse."
+</P>
+
+<P>
+"Of course it won't!" cried Bud. "Why, even in the short time the
+steers have been in Flume Valley, Billee, they've improved."
+</P>
+
+<P>
+"You say there's stock there now?" asked the old man, for he was
+gray-haired, "Well, if they've been thrivin' by themselves so far,
+what's the good of you an' your cousins campin' there to watch 'em eat?"
+</P>
+
+<P>
+"Lots of reasons," answered Bud, as he and his companion started up a
+hill, on the other side of which they would reach the water-hole, where
+the main trail from Diamond X came in. "For one thing this is
+something new, and dad wants it watched carefully. Then, too, the
+water pipe and reservoir will need looking after. But, more than
+anything else, it's Del Pinzo and his gang of rustlers."
+</P>
+
+<P>
+"Those scoundrels didn't get what they deserved for tryin' to run off
+our stock last year!" complained Billee. "Now they're raisin' ructions
+again; be they?"
+</P>
+
+<P>
+"They sure are!" declared Bud. "It wasn't that they didn't get what
+they deserved, for they were sentenced to long terms. But the trouble
+was they didn't stay in jail where they were put."
+</P>
+
+<P>
+"I reckon they look at it just the other way!" chuckled Billee.
+</P>
+
+<P>
+"Yes," agreed Bud. "But it's going to make trouble for dad and all the
+other cattle raisers around here having that bunch of Mexicans and
+Greasers loose. That's one reason why we've got to watch out at Flume
+Valley, where we're going to try to raise some cattle that will beat
+those at Diamond X. I'm glad you're going to be with me, Billee."
+</P>
+
+<P>
+"Hum! You don't care what sort of trouble th' old man gits into; do
+you, Bud?" and he smiled a toothless smile at his employer's son.
+"Well, it's all in th' day's work, I reckon. But I'm not expected t'
+come with you to-night; am I? Slim said I was to report t' him at the
+main buildin's."
+</P>
+
+<P>
+"No, you don't have to come right away," replied Bud. "I'm to meet
+Dick and Nort at the water-hole&mdash;they were due at our ranch this
+morning&mdash;and you're to come when you can."
+</P>
+
+<P>
+"Might as well be quick as sooner," laughed the old cowboy. "I don't
+take much to new-fangled notions. But orders is orders, I reckon."
+</P>
+
+<P>
+"Oh, there isn't so much new at Flume Valley," said Bud. "All it ever
+needed to make one of the best places in this part of the country for
+raising cattle was water. Now, since dad had the big pipe flume put in
+from Pocut River, where it can fill the reservoir and water the grass
+and the cattle at the same time, things are going to boom!"
+</P>
+
+<P>
+"They are to hear you tell 'em!" chuckled Billee. "Well, I wish you
+all good luck, Bud, I'll help all I can. I'll be over to-night, if I
+can make it, though it's some of a ride after a day's work."
+</P>
+
+<P>
+"Oh, I won't expect you," said Bud. "I've got everything all laid out
+for the camp there. Nort and Dick will be with me, but we'll be on the
+lookout for you to-morrow. Bring what things you need, and some grub.
+And if my mother has any pies baked, just pack a few of them."
+</P>
+
+<P>
+"Only a <I>few</I>?" asked Billee, with a grin.
+</P>
+
+<P>
+"As many as Nell will let you take," laughed Bud. "But there's Nort
+and Dick! Whoop! Oh, boy! Come a-runnin'!" and the young rancher
+beat a tattoo with his heels on the sides of his steed, and raced down
+the slope toward two other lads who, like himself, were attired in
+conventional western costume. Old Billee pulled his steed to a halt
+and watched the greetings.
+</P>
+
+<P>
+"It's a great thing to be young!" sighed the old man. "The greatest
+thing in the world! But maybe I can do something yet! Only I don't
+like that black jack&mdash;I shore don't! Never heard of anythin' but bad
+luck followin' one of them nimble cusses! I don't like it for a cent!"
+</P>
+
+<P>
+"Well, here we are!" cried Nort Shannon, flinging his broad-brimmed hat
+into the air, and catching it on the end of his .45 before the
+headpiece could touch the ground.
+</P>
+
+<P>
+"Came right on time, too! Zip Foster couldn't 'a' made it better!"
+joyously declared Bud, clapping his palm into that of Nort.
+</P>
+
+<P>
+"Haven't you run him off the ranch yet?" asked the other lad, who was
+rather short and stout, not to say fat.
+</P>
+
+<P>
+"Run who off?" asked Bud.
+</P>
+
+<P>
+"Zip Foster!" repeated Dick. "Last I heard of him&mdash;&mdash;"
+</P>
+
+<P>
+"Never mind <I>him</I>!" and Bud seemed somewhat annoyed at having mentioned
+the name. "Oh, but I'm glad you fellows are here! Have a good trip?
+Are you hungry? Did you have grub enough? Can you ride right out now?
+How's everybody at my house?"
+</P>
+
+<P>
+Nort looked at his western cousin, and then, with a deliberate motion
+pretended to mop his face free of some imaginary perspiration, brought
+out by the rapid-fire questions on his cousin's part.
+</P>
+
+<P>
+"Say! Go a bit easy, will you, Bud?" he begged. "One at a time! Line
+forms on this side!"
+</P>
+
+<P>
+"We're going right out with you, and everybody's fine!" answered Dick,
+summing up matters. "Your father said we were to ride out and meet you
+here at the water-hole. We've got as much of our outfits as we'll need
+for a few days, and so let's mosey along. Oh, but it's great to be
+back out west!"'
+</P>
+
+<P>
+"You got off a ripe one that time!" agreed Nort. "Who's that up
+there?" he asked, pointing to the figure of a solitary horseman on the
+hill down which Bud had ridden.
+</P>
+
+<P>
+"Looks like Yellin' Kid," commented Dick.
+</P>
+
+<P>
+"It's Old Billee," answered Bud. "He's going to be with us out at
+Flume Valley. Did dad tell you of the new venture?" he asked his
+cousins.
+</P>
+
+<P>
+"Yes, and it sounds good. Must have been quite a trick to bring water
+from Pocut River, Bud."
+</P>
+
+<P>
+"Well, it would have been if Professor Wright hadn't showed dad how to
+use an old underground water course for part of the way. Then it was
+easy. And say&mdash;you ought to see what a difference water has made in
+that valley! It was almost a desert before we irrigated."
+</P>
+
+<P>
+"I'm anxious to see it!" said Nort.
+</P>
+
+<P>
+"We can't get there any too soon to suit me," added Dick. "Just think!
+We're going to be our own bosses&mdash;boy ranchers for fair!"
+</P>
+
+<P>
+"You intimated plenty that time!" cried Bud. "Well, let's hit the
+trail!"
+</P>
+
+<P>
+The three boy ranchers started off, Nort and Dick accompanying Bud back
+over the way the latter had come. As they rode up the hill Old Billee
+passed on down another trail, leading to Diamond X proper.
+</P>
+
+<P>
+"Howdy, boys!" called the old cowboy from the distance to Nort and
+Dick. "See you a bit later over at your own ranch!" he added, and
+then, with a friendly wave of his hand, he went down into a little
+swale, or valley, and was lost to sight.
+</P>
+
+<P>
+"Now for some good times!" cried Bud, as he rode between his two
+eastern cousins, who had again come to spend the summer with him in the
+great western outdoors.
+</P>
+
+<P>
+"If it's anything like last year we sure will have a bang-up vacation!"
+declared Nort.
+</P>
+
+<P>
+"Well, I can't promise anything like that&mdash;with cattle rustling and
+digging up animals ten million years old," laughed Bud. "But I think
+we might have a little excitement."
+</P>
+
+<P>
+"How?" asked Nort and Dick eagerly.
+</P>
+
+<P>
+"Tell you later," promised Bud.
+</P>
+
+<P>
+They rode on, talking over old times and planning new ones, and as the
+shadows began to lengthen they rode down into a triangular valley, at
+one end of which a rude dam could be noticed, while, scattered over the
+green carpeted floor, were hundreds of grazing cattle.
+</P>
+
+<P>
+"Say, this is some slick place!" cried Dick.
+</P>
+
+<P>
+"The best ever!" affirmed Nort. "And is this where we are to camp and
+ranch it?"
+</P>
+
+<P>
+"Right here," declared Bud. "Course we haven't any ranch house yet.
+But we've got a tent&mdash;there it is," and he pointed to a white canvas
+shelter not far from the dam.
+</P>
+
+<P>
+"A tent! Oh, boy! better and better!" yelled Dick, as he urged his
+pony forward.
+</P>
+
+<P>
+As the three boy ranchers neared their headquarters, represented by two
+or three tents grouped together, there emerged from among them the
+figure of a man on horseback.
+</P>
+
+<P>
+"There's old Buck Tooth," said Bud.
+</P>
+
+<P>
+"Who?" asked the eastern cousins.
+</P>
+
+<P>
+"Buck Tooth&mdash;a Zuni Indian that dad picked up somewhere. He's one of
+the best herd-riders you'd want, and he and I are great friends.
+Wonder what's the matter, though? He acts as though something had
+happened."
+</P>
+
+<P>
+Bud pulled rein, to allow a better observation of the figure that was,
+obviously, riding out to meet him. Nort and Dick also halted their
+ponies. But Buck Tooth rode to meet them at great speed, sitting in
+the saddle as though part of it and the horse. He rode in a manner
+that made Nort and Dick envy him.
+</P>
+
+<P>
+"What's the matter, Buck?" asked Bud, as soon as the Indian was within
+hailing distance. And then Nort and Dick could see why he was called
+that. A large, yellow-stained tooth protruded from his mouth, giving
+him not exactly a pleasant expression.
+</P>
+
+<P>
+"What's wrong, Buck, you ride so <I>pronto</I> like?" demanded the young
+western ranch boy.
+</P>
+
+<P>
+"Heap wrong!" came the answer in guttural tones. "You no shut off
+water in pipe; eh?"
+</P>
+
+<P>
+"Shut off the irrigation water? I should say not!" cried Bud. "Why,
+has anyone?"
+</P>
+
+<P>
+"Water no come! All gone! No run splash-splash now!" and Buck Tooth
+waved his hand toward the reservoir made by a dam that curved out in a
+half circle from the wall of natural rock.
+</P>
+
+<P>
+"The water gone!" cried Bud. "This is strange! Let's have a look!"
+</P>
+
+<P>
+He and his cousins rode at top speed to the reservoir that had
+reclaimed Flume Valley from the semi-desert it had long been.
+Dismounting, they climbed the slope and saw that from the great iron
+pipe, which was wont to spout a sparkling stream, there came only a few
+drops and trickles.
+</P>
+
+<P>
+"It's disappeared!" said Bud in a low voice. "The water has taken
+another course! This means the end of Flume Valley, I reckon!"

+A NIGHT RIDE
+</H3>
+
+<P>
+The boy ranchers stood looking down into the reservoir, which was
+almost full of water, but which was slowly running out through the
+different gates, some to concrete drinking troughs where thirsty cattle
+congregated, and some to distant meadows where it supplied moisture for
+the grass on which the steers of Diamond X Second fed. From the
+slightly ruffled surface of the reservoir, as the evening wind blew
+across the water, the gazes of Bud, Nort and Dick sought the faces of
+one another.
+</P>
+
+<P>
+"This looks had!" murmured Bud, while Buck Tooth, the Zuni Indian,
+grunted something in his own incomprehensible dialect.
+</P>
+
+<P>
+"What does it mean?" asked Nort, as he looked down the slope from the
+reservoir to the group of tents that was to form the home of himself,
+his brother and cousin for several months, while they were in camp.
+</P>
+
+<P>
+"It means the water supply, on which I depended to raise these steers,
+has petered out," answered Bud, and there was a worried note in his
+voice.
+</P>
+
+<P>
+"You mean stopped for good?" asked Dick.
+</P>
+
+<P>
+"I hope not," went on Bud. "But from what you can see&mdash;no water coming
+through the pipe line that dad laid to the Pocut River&mdash;I should say
+there was a break in it somewhere, and it will have to be fixed right
+away&mdash;that is, if I'm to keep these cattle here," and he looked down
+the valley where the bunches of steers were ever on the move, seeking
+new places to feed, or coming to drink water from the supply flowing
+out of the reservoir.
+</P>
+
+<P>
+"We seem to have struck a job right off the bat!" remarked Dick, as he
+picked up a stone and tossed it into the reservoir.
+</P>
+
+<P>
+"Just as we did when we came west before, and had to jump out and help
+the queer professors," added Nort. "But we're ready to go to work,
+Bud. All you'll have to do is say the word and&mdash;&mdash;"
+</P>
+
+<P>
+But Bud did not seem to be paying much attention to what his cousin was
+saying. Instead his gaze followed that of his Zuni Indian helper.
+Buck Tooth was looking off up the hill under which the big pipe ran to
+the distant Pocut River on the other side of the mountain. And as Bud
+and Buck Tooth looked, and as the gaze of Nort and Dick was bent in the
+same direction, they all beheld a figure on the back of a fast-moving
+pony, riding up the trail that led over Snake Mountain.
+</P>
+
+<P>
+"Who's that, Buck? See him!" yelled Bud.
+</P>
+
+<P>
+"No can tell. Old Billee, mebby!" grunted the Indian.
+</P>
+
+<P>
+"No! Old Billee just left me! He's back at the ranch house. But
+that's a stranger, and I don't like strangers sneaking around my
+ranch&mdash;especially when there's a break just happened to my pipe line!"
+exclaimed Bud. "I'm going to look into this!"'
+</P>
+
+<P>
+"Hi there! Hold on a minute! I want to talk to you!" he yelled,
+making a megaphone of his hands and directing it at the figure on the
+back of the sturdy pony that was scrambling up the mountain trail.
+"Wait a minute!"
+</P>
+
+<P>
+But this the stranger seemed unwilling to do. The watching group near
+the reservoir saw him raise his quirt, or short whip, and bring it down
+savagely on the back of the pony, which, already, was doing its best to
+carry its master out of distance.
+</P>
+
+<P>
+Then, with a quick motion, Bud drew his .45, and though both Nort and
+Dick saw him aim it high above the man's head, in order to shoot over
+him, horse and rider went down in a tumbled heap at the sound of the
+report, which followed as Bud pulled the trigger.
+</P>
+
+<P>
+"You've winged him!" cried Dick.
+</P>
+
+<P>
+"Shucks! Didn't mean to hit him&mdash;just shot to scare him!" declared
+Bud. "But we'll have to see about it now! Come on!" he cried, and he
+ran down the side of the reservoir to where he had left Sock, his pony,
+followed by Dick and Nort who also headed for their steeds.
+</P>
+
+<P>
+"Hu!" grunted the Indian, as he came on down more leisurely. "No
+water&mdash;man shot&mdash;new boys come&mdash;big time, mebby! Hu!"
+</P>
+
+<P>
+And Buck Tooth was more than right. Big times impended in Flume Valley.
+</P>
+
+<P>
+While Bud Merkel and his two cousins who had arrived from the east only
+the day before were mounting their ponies, to ride up the side of Snake
+Mountain, and seek the man Bud had shot, I shall have a chance to tell
+my new readers something about the boy ranchers, and the volume that
+immediately precedes this one.
+</P>
+
+<P>
+The book is entitled "The Boy Ranchers; or Solving the Mystery at
+Diamond X." Norton, or Nort, and Dick, or Richard, Shannon were sons
+of Mr. and Mrs. Thornton Shannon, and their home was in the cast. When
+Mr. Shannon, the summer previous, had been obliged to make a trip to
+South America, with his wife, he sent his sons to spend their vacation
+at Diamond X, one of the western cattle ranches owned by Henry Merkel,
+Mrs. Shannon's brother.
+</P>
+
+<P>
+Almost immediately on their arrival Nort and Dick, who were then
+rightly classed as "tenderfeet," became involved in a strange mystery.
+A call for help came, and they took part in the rescue of two college
+professors who had been attacked by a band of Mexicans and "Greasers,"
+the latter being a low-class Mexican.
+</P>
+
+<P>
+The professors were rescued, but the mystery only deepened. What it
+was, and how it came to be solved, you will find set down at length in
+the first volume. Sufficient to say, here, that Nort and Dick, as it
+were, "cut their eye teeth," during the exciting experiences that
+followed their arrival at Diamond X.
+</P>
+
+<P>
+The eastern boys learned how properly to ride a pony cowboy fashion,
+they learned the use of the branding iron, the lariat and "gun," as the
+.45 revolvers were universally called. They learned, also, how to
+"ride herd," "ride line" and how to live in the open, with the prairie
+grass for a bed and the star-studded sky for a blanket, their saddle
+forming the pillow.
+</P>
+
+<P>
+Mr. Merkel, Bud's father, owned several ranches besides Diamond X, so
+named because that brand was used on the cattle from it. He had Square
+M, and Triangle B, the explanation of which names are obvious.
+</P>
+
+<P>
+When it came time for Nort and Dick to return east, as winter
+approached, they left, promising to return as soon as their summer
+vacation should arrive, for they were determined to become boy ranchers
+in earnest, an ambition in which Bud shared.
+</P>
+
+<P>
+Now it was summer again, and Nort and Dick had once more journeyed to
+their uncle's ranch, to be met by Bud, as arranged, at the water-hole.
+For between the two visits of the easterners some changes had been made
+at Diamond X.
+</P>
+
+<P>
+Bud had been clamoring to be allowed to raise some cattle "on his own,"
+and his father had consented. Off to the north of Diamond X, and in a
+depression between the Snake Mountains on the east and Buffalo Ridge on
+the west, was another valley, well sheltered from the wintry blasts.
+This valley was owned by Mr. Merkel, and though part of it was
+timbered, and some scattered sections produced an excellent variety of
+grass for stock, there was no dependable source of drinking water
+available. And without water at hand it is impossible to raise cattle
+in the west&mdash;or any place else, for that matter.
+</P>
+
+<P>
+How to get water to "Flume Valley," as it came to be called, was a
+problem. It would have been put to use raising cattle long before this
+had Mr. Merkel been able to get any water there for the animals to
+drink, and also some to irrigate the more arid portions so that fodder
+would grow.
+</P>
+
+<P>
+At the foot of the eastern slope of Snake Mountains ran the Pocut
+River, which served to supply not only Diamond X, Square M and Triangle
+B ranches with water, but also those of Double Z and Circle T, the
+respective holdings of Hank Fisher and Thomas Ogden. But though Pocut
+River gave plenty of water to Bud's father and the other ranchmen, none
+was available for the isolated valley which, except for this, would
+have been an ideal place to raise steers.
+</P>
+
+<P>
+And it was here that the good services of Professor Wright, one of the
+scientists mentioned in the first volume, came into play. For
+Professor Wright discovered an ancient underground water course,
+connecting with Pocut River, and when this had been partly tunneled,
+re-opened at places where it had caved in, and a big iron pipe laid
+part of the way, water came gushing out into Flume Valley, as Bud
+renamed the place, it having been called Buffalo Wallow before that
+time; probably when there was water in it and the buffalo made it a
+rendezvous.
+</P>
+
+<P>
+And when the water came through the iron pipe, falling into the
+reservoir that had been built to hold it in reserve, Bud was allowed to
+begin his experiment in stock raising.
+</P>
+
+<P>
+His father provided him with the cattle, and Bud was a boy rancher in
+reality now. His cousins had agreed to help him in the venture on
+their arrival, and Bud had been expecting them when he rode out with
+Old Billee that day. Old Billee was one of the Diamond X cowboys, and
+he might have been made a foreman, except that he had no executive
+ability. He could do as he was told, and that was about all. He was
+reliable and dependable, but had no initiative for big undertakings.
+Old Billee, with Buck Tooth and some other cowboys, had been assigned
+to help Bud in his venture.
+</P>
+
+<P>
+As Bud has told his cousins, when he rode to meet them at the
+water-hole, on the trail from Diamond S ranch, there was no time, yet,
+to construct ranch houses in Flume Valley. Tents would have to serve
+the purpose, and the boys were rather pleased, than otherwise, with
+this.
+</P>
+
+<P>
+"It will be just like camp!" said Bud.
+</P>
+
+<P>
+And so the easterners had arrived, and, almost with the moment of their
+coming, there had begun the first act in what was to prove a drama of
+almost tragic happenings.
+</P>
+
+<P>
+"You stay at the camp, Buck!" called Bud to the Zuni, as the three boy
+ranchers mounted and prepared to ride up to where the unknown man had
+collapsed after Bud had fired. "You stick around! Old Billee, or some
+of the boys from Diamond X may ride over, though I don't expect them
+until morning. Stay here, Buck!"
+</P>
+
+<P>
+"Me stick!" gutturally answered the Indian. "You catchum man
+mebby&mdash;git back water."
+</P>
+
+<P>
+"Maybe," agreed Bud, as he and his cousins trotted off up the trail,
+which wound around the reservoir and over the mountain.
+</P>
+
+<P>
+Dusk was falling as the boys reached the vicinity of the place whence
+they had seen the lone rider emerge from the bushes, spurring his horse
+up the rocky trail that led over Snake Mountain, as the whole ridge was
+known.
+</P>
+
+<P>
+"Must have been about here," said Dick, as he reined in his steed, for
+which the panting animal, doubtless, was grateful.
+</P>
+
+<P>
+"Little farther on, I think," said his brother.
+</P>
+
+<P>
+"No, it was right here," declared Bud, as he dismounted and began to
+scan the ground. "Here's where his horse slipped," and he pointed to
+the tell-tale marks on the trail.
+</P>
+
+<P>
+"Yes, and look&mdash;you hit him all right!" added Dick.
+</P>
+
+<P>
+He indicated some dull, red spots on the stones. Bud reached down and
+gingerly touched them.
+</P>
+
+<P>
+"Blood!" he murmured. "Guess I did wing him&mdash;or the horse&mdash;but I don't
+see how I could. I fired high."
+</P>
+
+<P>
+"But where did he go?" asked Nort, following the marks left by a horse
+that had, obviously, been hard pressed. "See, the sign goes right up
+to this rocky wall, and then stops. He couldn't have gotten up there,
+could he?"
+</P>
+
+<P>
+"Not unless he wore wings," said Bud grimly. "But it's getting too
+dark to see well. We'd better be getting back to camp."
+</P>
+
+<P>
+"I thought you were going to follow this up, and see what had happened
+to your pipe line," suggested Dick.
+</P>
+
+<P>
+"I am, but we can't ride on without some grub. No telling what we may
+stack up against. We'll have to make a night ride of it, I'm thinking,
+and I'd like to have Buck Tooth along. He's a shark on following a
+blind trail. Come on, we'll go back to camp, get some grub and then
+take this up again. I hope I didn't kill him, though," murmured Bud,
+as he again leaped to the saddle, an example followed by Nort and Dick.
+</P>
+
+<P>
+"Who was he?" asked the latter, puffing slightly from his exertions,
+for he was much stouter than his brother Nort.
+</P>
+
+<P>
+"Search me!" replied Bud. "Looked mighty suspicious, though, the way
+he rode off. And if he wasn't up to something wrong he'd 'a' stopped
+when I hailed him."
+</P>
+
+<P>
+"Do you think he had anything to do with the break in the pipe?" asked
+Nort.
+</P>
+
+<P>
+"You've got me again," confessed his western cousin. "We'll have to
+make a night ride of it and find out."
+</P>
+
+<P>
+They rode back to the camp tents, to find Buck Tooth calmly smoking his
+red-stone Indian pipe, and gazing off in the darkening distance at
+nothing at all, as far as the boys could determine.
+</P>
+
+<P>
+"Anybody been around, Buck?" asked Bud.
+</P>
+
+<P>
+"Nope!" was the answer. "You catchum dead man?"
+</P>
+
+<P>
+"Not a sign, Buck! Beckon he must have dug a hole and pulled it in
+after him. But we've got to find out what's the matter with the pipe
+line. There's only a few days' supply of water in the reservoir.
+Rustle out some grub, and we'll ride over the mountain."
+</P>
+
+<P>
+"Um," grunted the Zuni, and a little later, after a hasty meal of
+flapjacks, bacon and coffee, the boy ranchers, with the old Zuni
+Indian, started on a night ride over the mountain trail, in the general
+direction of the pipe line, the supply of fluid for which had so
+mysteriously stopped.
+</P>

+<H3 ALIGN="center">
+THE WARNING
+</H3>
+
+<P>
+"Will it be safe to leave our camp alone, like this?" asked Nort, as he
+and his companions rode off, leaving behind them the white tents,
+gleaming in the wondrous light of a full moon.
+</P>
+
+<P>
+"Why not?" inquired Bud. "It won't walk away."
+</P>
+
+<P>
+"No, but some one might come in and take everything."
+</P>
+
+<P>
+"There isn't much worth taking. You brought your old stuff with you,
+we have our ponies, so all they could snibby would be the camp dishes,
+and they aren't worth the risk."
+</P>
+
+<P>
+"Could they drive off any of your cattle?" asked Dick.
+</P>
+
+<P>
+"Why don't you say <I>our</I> cattle?" asked Bud with a smile, which was
+plainly to be seen in the brilliant moonlight. "You fellows are in
+this venture with me, you know."
+</P>
+
+<P>
+"We haven't yet gotten used to thinking of it that way," remarked Nort,
+as he rode beside Buck Tooth. The old Zuni Indian managed to keep pace
+beside the boys without ever urging his pony forward, a trick of riding
+which even Bud envied.
+</P>
+
+<P>
+"Well, you'd <I>better</I> get used to it," was the laughing retort. "Your
+dad staked you to part of the expenses of this deal, same as mine did
+me, and of course you'll share in the profits&mdash;if there are any," Bud
+added rather dubiously. "And if we don't get that water back there
+won't be enough to make you need a hat to carry 'em off."
+</P>
+
+<P>
+"As bad as that?" inquired Nort.
+</P>
+
+<P>
+"Oh, I'm not saying it's bad&mdash;<I>yet</I>!" exclaimed Bud. "There may be
+just a stoppage in the pipe, which can easily be cleaned out. Or, it
+may be&mdash;something else."
+</P>
+
+<P>
+But what else it might be he did not say, and Nort and Dick were not
+sufficiently familiar with irrigation and flume lines to hazard a
+guess. But they knew enough about their cousin to tell that he was
+worried.
+</P>
+
+<P>
+"What do you plan to do?" asked Dick, as the four rode on, their ponies
+occasionally stumbling as they mounted the rocky trail that led over
+Snake Mountain. "Look for that man&mdash;the one you&mdash;&mdash;"
+</P>
+
+<P>
+"The one I <I>didn't</I> shoot!" interrupted Bud. "I'm as sure I didn't hit
+him as I am that we four are here this minute. I know I fired too
+high!"
+</P>
+
+<P>
+"Unless the bullet hit a rock and glanced down," suggested Nort.
+</P>
+
+<P>
+"Well, yes, that may have happened," admitted Bud. "But if he was
+badly hurt he couldn't get away, as he did."
+</P>
+
+<P>
+"Could he have fallen into any hole or gully?" asked Dick. "We didn't
+look for that."
+</P>
+
+<P>
+"He might have," admitted the western lad. "But what I'm looking for,
+now, isn't that fellow, who may or may not be shot, but for the break
+in my flume&mdash;that's what I want to locate. Once I get the water so
+it's running back in my reservoir I'll feel better. For if there's a
+permanent shut-off we might as well move out of Flume Valley," he went
+on. "The cattle would just naturally die of thirst!"
+</P>
+
+<P>
+"Isn't there any water at all?" asked Nort, as he pulled his pony up
+sharply when the animal stumbled.
+</P>
+
+<P>
+"Not enough to water all the stock I aim to raise," answered Bud. "At
+the far end of the valley&mdash;away from our camp&mdash;the grass grows pretty
+well, for some rain does fall there once in a while. But there isn't a
+water-hole worth the name, and you know what happens to cattle when
+they can't get a drink!"
+</P>
+
+<P>
+"I should say so!" commented Nort, for he and his brother had seen some
+of the terrible suffering caused by animals having to be driven long
+distances without any water being available. "Then the pipe line is
+your only hope?"
+</P>
+
+<P>
+"That, and the ancient underground watercourse it connects with to
+bring water from the Pocut River," replied Bud. "You see, there's a
+sort of natural tunnel under the mountain, and this was once an old
+river bed. I suppose, or at least Professor Wright has told us, that
+once this tunnel was full-up with water. But there was a change in the
+direction of the old stream, and the water tunnel dried up. However,
+it didn't cave in, except in a few places, and we now use it to bring
+water to Flume Valley. There is really only a comparatively short
+length of pipe at either end, one end being where the water from the
+Pocut River enters, and the other where the pipe delivers the water to
+our reservoir."
+</P>
+
+<P>
+"How are you going to find the break?" asked Dick.
+</P>
+
+<P>
+"Or stoppage?" suggested Nort.
+</P>
+
+<P>
+"Well, I aim to ride over the mountain tonight," answered Bud, "and see
+if all is clear at the river intake end of the line. If it is, I'll
+know there must be a stoppage, or break, somewhere inside the old water
+tunnel."
+</P>
+
+<P>
+"How you going to find that?" inquired Nort.
+</P>
+
+<P>
+"Why, we'll get lanterns and ride through," replied Bud. "That's easy!"
+</P>
+
+<P>
+"Ride through an underground river!" cried Dick. "You can't!"
+</P>
+
+<P>
+"No, we couldn't if the old underground river course was <I>full</I>,"
+agreed Bud, "but it <I>isn't</I>. There's only a comparatively small amount
+of water flowing through the old course, which is wide enough for two
+of us to ride or walk abreast, and twice as high as you need. I've
+ridden through more than once. It's like a long, natural tunnel under
+the mountain, with water flowing in the center depression, so to speak."
+</P>
+
+<P>
+"Must be rather spooky inside there," suggested Nort.
+</P>
+
+<P>
+"It is a little; and it's nearly an all-day's ride. But it's the only
+way to find the trouble. Professor Wright said that some day the water
+might work through, and go off on a new course, and in that case I'd be
+dished until I could stop up the break."
+</P>
+
+<P>
+"Well, we'll help all we can," offered Nort.
+</P>
+
+<P>
+"Sure thing!" echoed his brother.
+</P>
+
+<P>
+"We'd better take it a bit easy now," spoke Bud, as the ascent of the
+mountain became more steep. "We don't want to wind the ponies, and we
+may have a hard day ahead of us to-morrow."
+</P>
+
+<P>
+"It <I>is</I> quite a climb," admitted Nort. "Are we going to ride all
+night?"
+</P>
+
+<P>
+"No, we'll turn in about midnight," said Bud. "But this will give us a
+start so we can get to the Pocut River end of the flume by morning. We
+can stop any time you fellows want to."
+</P>
+
+<P>
+"Oh, we aren't tired!" Dick hastened to say, a sentiment with which his
+brother agreed. "This is as much fun as riding herd, and driving off
+the cattle rustlers."
+</P>
+
+<P>
+"Glad you like it," commented Bud. "And the rustlers might as well
+drive off our stock, if we don't soon get this water to running again.
+Old Billee said I'd have bad luck when that black rabbit crossed my
+path, and it sure is coming!"
+</P>
+
+<P>
+"What black rabbit was that?" asked Nort, curiously.
+</P>
+
+<P>
+"One that gave me a tumble when I was riding to meet you," answered
+Bud. "I never saw one before, and I don't want to again. Not that I'm
+superstitious, but there sure is something queer about <I>this</I>! I don't
+like it for a cent!"
+</P>
+
+<P>
+The boy ranchers and the Zuni Indian rode on, mounting higher and
+higher along the mountain trail, heading for the summit. And when they
+reached it, and Bud, by a glance at his watch, announced that it was
+midnight, he followed with the suggestion that they camp there for the
+remainder of the night.
+</P>
+
+<P>
+"We can make the rest of the trip in a couple of hours, for it's down
+hill," he said.
+</P>
+
+<P>
+"Camp suits me," murmured Nort, and soon, after a bite to eat, they
+rolled themselves in their blankets, having tied the ponies to scrub
+bushes, and went to sleep. The riding of the boys, coupled with the
+pure air they had breathed, brought them slumber almost at once, and
+even Buck Tooth, alert as he usually was, neither saw nor heard
+anything of the sinister visitor who came softly upon the sleeping ones
+during the night hours.
+</P>
+
+<P>
+For there did come a visitor in the night, as evidenced by a scrawled
+warning, on a dirty piece of paper, fastened to a stubby tree by a
+long, sharp thorn.
+</P>
+
+<P>
+It was this fluttering bit of paper that caught Dick's eye when he
+awakened, rather lame and stiff, and stretched himself in his blanket
+as the sun shone in his eyes next morning.
+</P>
+
+<P>
+"Hello!" he cried, taking a hasty look around to see if Bud had,
+perchance, ridden away without awakening his companions, and had left
+this note to tell them so. "What's the idea?" and then Dick noticed
+that all three of his companions were stretched out near him, and the
+four ponies were standing together not far away.
+</P>
+
+<P>
+"What idea?" asked Bud, sitting up and rubbing his eyes.
+</P>
+
+<P>
+"That special delivery letter," and Dick pointed to it. "Wasn't here
+last night," he went on, "for I tied Blackie to that tree before I
+staked him out. What is it?"
+</P>
+
+<P>
+Bud rolled out of his blanket, and took the piece of paper from the
+tree.
+</P>
+
+<P>
+"It's a warning!" he announced.
+</P>
+
+<P>
+"A warning?" cried Nort and Dick, while Buck Tooth began making a fire.
+</P>
+
+<P>
+"Yes," went on the boy rancher. "Here's what it says:
+</P>
+
+<P>
+"'Don't take no more watter frum Pocut River if you want to stay
+healthy!'"
+</P>
+
+<P>
+"Whew!" whistled Dick. "What does that mean?"
+</P>
+
+<P>
+"Just what I'd like to know," said Bud, and then all three boys
+started, and looked toward the upward slope of the mountain, down which
+they had partly descended. For there came rolling toward them a mass
+of dirt and stones, indicating the approach of some one.

+CHAPTER IV

+
+<H3 ALIGN="center">
+A STRANGE REAPPEARANCE
+</H3>
+
+<P>
+Characteristic it was of Bud Merkel, being a son of the west as he was,
+that his hand instinctively sought the leather holster whence protruded
+the grim, black handle of his .45. But he did not draw the weapon, nor
+did Nort or Dick pull theirs, which they had started to get out when
+they noted Bud's action.
+</P>
+
+<P>
+For Bud smiled when he had a glimpse of the newcomer, and Buck Tooth,
+who had glanced up from where he was making the fire, gave a grunt of
+welcome.
+</P>
+
+<P>
+"Babe!" exclaimed Nort, as he recognized the fat assistant foreman of
+Diamond X ranch. "Babe!"
+</P>
+
+<P>
+"Sure! Who'd you think it was?" came the smiling question. "Looks
+like you had an idea it might be one of them rustlers that made trouble
+when you fellers was here before! Eh?
+</P>
+
+<P>
+"Glad t' see you two <I>ex</I>-tenderfeet," and Babe Milton grinned broadly
+as he accented the <I>ex</I>, and held out a welcoming hand to Nort and
+Dick. "They said you was comin' back to Diamond X, but I sorter missed
+you&mdash;been out tryin' t' locate a bunch of strays," he confided to Bud,
+"an' I didn't have no luck! Glad to meet yo' all, though, powerful
+glad! 'Specially on account of that there coffee!" and he sniffed the
+air as he caught the aroma of the fragrant pot Buck Tooth was putting
+on to boil.
+</P>
+
+<P>
+"But what are you lads doing so far from Diamond X?" Babe went on, when
+they had moved over to the camp fire, the blaze of which was genially
+warm this cool morning on the mountain.
+</P>
+
+<P>
+"We aren't stopping there this trip," said Nort.
+</P>
+
+<P>
+"We're 'on our own,'" proceeded Bud. "I'm raising cattle in the old
+Buffalo Wallow Valley&mdash;Flume I call it now."
+</P>
+
+<P>
+"Oh, yes, I did hear you were going to tackle that," spoke Babe.
+"Didn't know you'd got stocked up, though. Well, I've been over at
+Square M for so long I don't hear no real news no more. Gosh! But we
+did have some excitement the time those professor chaps pulled that
+<I>Trombone</I> out of the ground; didn't we, Bud?" he chuckled.
+</P>
+
+<P>
+"Triceratops, Babe! Triceratops!" corrected Bud, laughing at the
+expression of the fat assistant foreman's face.
+</P>
+
+<P>
+"I never could remember the name of them musical pieces, nohow!" sighed
+Babe. "Fond as I am, too, of singing," and, taking a long breath, he
+bellowed forth on the unoffensive morning air this portion of a ballad:
+</P>
+
+<P CLASS="poem">
+"Sing me to sleep with a spur for a rattle,<BR>
+Fill up the biscuits with lead.<BR>
+Coil me a rope 'round th' ole weepin' willow,<BR>
+Curl my feet under my head!"<BR>
+</P>
+
+<BR>
+
+<P>
+"Glad you feel that way about it," remarked Bud, rather soberly, as
+they squatted around the fire for breakfast, which Buck Tooth seemed to
+have prepared in record time.
+</P>
+
+<P>
+"What's bit you?" asked Babe, pausing with a smoking flapjack half way
+to his mouth, while in his other hand he held a steaming tin cup of
+coffee. "Git out th' wrong side of th' saddle this mornin'?"
+</P>
+
+<P>
+"No, but there's trouble over at the valley," explained Bud. "The
+water has stopped running and&mdash;&mdash;"
+</P>
+
+<P>
+"The <I>water</I> stopped running!" interrupted Babe.
+</P>
+
+<P>
+"Yes, and when we start out, intending to see what's the trouble, we
+get this warning," and Bud extended the dirty piece of paper that had
+been fastened to the tree with the thorn.
+</P>
+
+<P>
+"Whew-ee-ee!" whistled Babe, as he read the scrawl of misspelled words.
+He opened his mouth again, to intone another of the hundred or more
+verses of his favorite cowboy song, but Bud motioned to him to refrain.
+</P>
+
+<P>
+"Don't you like my singin'?" asked Babe, a bit hurt.
+</P>
+
+<P>
+"Yes, but I want to ask you some questions," went on Bud. "You say
+you've been out looking for strays?"
+</P>
+
+<P>
+"Yep; prospectin' up and down Snake Mountain all yist'day an' part of
+th' night. My grub giv' out with supper last night, an' I was hopin' I
+might even run into a bunch of Greasers, when I saw you folks spreadin'
+th' banquet table here."
+</P>
+
+<P>
+"Glad you joined us," remarked Nort.
+</P>
+
+<P>
+"So'm I," mumbled Babe, his mouth full of bacon and flapjacks. "But
+what's your questions, Bud? Shoot!"
+</P>
+
+<P>
+"Did you see anybody who might have written this?" and the boy rancher
+again read the sinister warning:
+</P>
+
+<BR>
+
+<P>
+"'Don't take no more watter frum Pocut River if you want to stay
+healthy.'"
+</P>
+
+<BR>
+
+<P>
+"Why, no, I didn't see nobody," spoke Babe, with more force than
+grammar. "'Tain't a joke; is it?"
+</P>
+
+<P>
+"Not when I tell you the water has stopped running," said Bud.
+</P>
+
+<P>
+"So you did! Hum, that's mighty queer like!" mused the assistant
+foreman, who had, early in the spring, been transferred to Mr. Merkel's
+Square M ranch from Diamond X. "But some of us rather thought there'd
+be trouble when your paw dammed up the river to shunt some of it
+through the old water course over to Buffalo Wallow. Hank Fisher
+claims his water supply has been lessened by what your paw did, Bud."
+</P>
+
+<P>
+"That's all bosh!" exclaimed Bud. "There's as much water for Hank
+Fisher as he ever had at Double Z. Besides, this isn't his way of
+doing business. He's as mean as they make 'em, but he'll come out in
+the open and tell you what he thinks of you."
+</P>
+
+<P>
+"Yes, Hank is that way&mdash;<I>sometimes</I>," agreed Babe cautiously. "At th'
+same time I wouldn't put it past him. Better tell your paw about this,
+Bud. You got grit&mdash;all three of you!" and he included the other boys
+in his glance. "But you can't fight Hank Fisher, Del Pinzo and that
+onery gang of Greasers and Mexicans!"
+</P>
+
+<P>
+"There!" cried Nort, clapping his hand down on his outstretched leg.
+"That's who that man was&mdash;Del Pinzo!"
+</P>
+
+<P>
+"What man?" asked Babe.
+</P>
+
+<P>
+"The one Bud shot."
+</P>
+
+<P>
+"What's that?" cried Babe, half starting to his feet. "Did you shoot
+somebody?"
+</P>
+
+<P>
+"Well, I may have <I>creased</I> him," admitted the boy, using a word to
+denote a grazing bullet wound, hardly more than a scratch.
+</P>
+
+<P>
+"Whew-ee-ee!" whistled Babe again. "This sounds like old times! Let's
+have the hull yarn, Buddy!" he appealed.
+</P>
+
+<P>
+Whereupon Bud related how he had ridden from his new ranch&mdash;Diamond X
+Second&mdash;to meet his cousins whom he expected. He told of finding the
+stream of water shut off, of the appearance of the man, the shot, his
+sudden vanishing, and the subsequent night ride of the boys.
+</P>
+
+<P>
+"That was Del Pinzo, I'm sure of it!" declared Nort. "I was trying to
+think where I'd seen him before, and now I remember!"
+</P>
+
+<P>
+"You couldn't very well forget Del Pinzo," declared Bud. "But this
+wasn't he. That isn't saying that it might not have been, of course,"
+he added, "for I understand he broke jail, after they caught him and
+sent him up for rustling our cattle. No, this wasn't that slick
+Mexican, Nort."
+</P>
+
+<P>
+"Who was it?" asked Babe, helping himself to another of the flapjacks
+which Buck was making in a skillet over the greasewood fire.
+</P>
+
+<P>
+"That's what we don't know," said Bud. "He just naturally vanished,
+the way my water did. What are you going to do, Babe?"
+</P>
+
+<P>
+"Well, I ought t' keep on lookin' for them strays your paw's so anxious
+about," was the answer. "But I reckon I got time t' mosey along with
+you. You say you're goin' down to the river?"
+</P>
+
+<P>
+"Yes, to see if there's anything wrong at the intake pipe," Bud
+answered.
+</P>
+
+<P>
+"Then I'll go with you," offered Babe. "And before you try that ride
+through the old water course, under the mountain, you'd better call up
+your paw."
+</P>
+
+<P>
+"What for?" Bud wanted to know.
+</P>
+
+<P>
+"Well, he mightn't altogether like it. There's a risk, an' he may want
+t' send some of us with you. It's easy t' get him on the 'phone from
+the dam."
+</P>
+
+<P>
+"Yes," agreed Bud, "I s'pose I had better do that." He remembered that
+where Pocut River had been dammed to enable water to flow into the pipe
+line, and then through the old river course to his reservoir, there was
+a general store, which boasted of a telephone.
+</P>
+
+<P>
+A little later, breakfast having been finished, the party, now
+including Babe, reached the Pocut River. There an inspection showed
+the water from the river above the dam running freely into the pipe
+that carried it to Flume Valley.
+</P>
+
+<P>
+"Nothing wrong here," remarked Bud as he looked into the dark tunnel
+which received one end of the pipe. And it was through this natural
+tunnel, extending under the mountain, being the course of an old
+stream, that the boy ranchers proposed riding.
+</P>
+
+<P>
+"No, th' trouble must be somewhere inside," agreed Babe. "But call up
+your paw, Bud."
+</P>
+
+<P>
+Which Bud did, learning from his father at Diamond X, that Old Billee
+had departed, early that morning, to take up his abode at the camp in
+the valley.
+</P>
+
+<P>
+"Better wait until Old Billee reaches your place, and then call him
+up," suggested Mr. Merkel to his son over the wire, for there was a
+'phone in Bud's camp. It seemed rather an incongruity, but it was a
+great convenience, since it connected directly with Diamond X, Triangle
+B and Square M ranches, as well as with the regular lines.
+</P>
+
+<P>
+There was nothing to do but wait until Old Billee might be expected to
+have reached the camp in Flume Valley, and after several hours Bud
+called up his own new ranch headquarters.
+</P>
+
+<P>
+"They don't answer," Central reported.
+</P>
+
+<P>
+"He's taking his time," commented Babe.
+</P>
+
+<P>
+But an hour or so later, after several other trials, the voice of Old
+Billee came back over the wire from miles distant.
+</P>
+
+<P>
+"Hello! Hello there! Wassa matter? Wassa matter?" demanded the voice
+of the old cowpuncher. "Where's everybody, anyhow? Nobody here but
+me!"
+</P>
+
+<P>
+"We're over at the dam&mdash;Pocut River," called Bud into the instrument.
+"Say, Billee, something happened at my place last night. The water
+stopped, and we came over here to see where the stoppage was. But it's
+all right here. How about you there?"
+</P>
+
+<P>
+"All serene here, Bud, all serene! Wait a minute and I'll take a look
+at your reservoir. I can see it from the tent where you got this
+talkin' contraption strung. You say the water stopped last night?"
+</P>
+
+<P>
+"Stopped complete, Billee," Bud answered back over the wire.
+</P>
+
+<P>
+"Well then, if there's any comin' over the spillway, now, it's a sign
+she's runnin' here ag'in, I take it!"
+</P>
+
+<P>
+"Sure thing. But is she running?" asked Bud, anxiously.
+</P>
+
+<P>
+"Wait a minute, an' I'll take a look. Hold on to that there wire!"
+</P>
+
+<P>
+"I'll hold it!" promised Bud, smiling at his cousins.
+</P>
+
+<P>
+There was a moment of anxious waiting and, in fancy, the boy ranchers
+could see Old Billee going to the tent flap and looking toward the
+reservoir.
+</P>
+
+<P>
+"Hello, Bud!" presently came the call over the wire.
+</P>
+
+<P>
+"Hello, Billee. What about it?"
+</P>
+
+<P>
+"Water's there all right! Must 'a' come back in th' night! She's
+runnin' fine now!"

+ANOTHER WARNING
+</H3>
+
+<P>
+Bud Merkel was about to hang up the receiver, with a blank and
+uncomprehending look on his face, when Babe caught the black rubber
+earpiece from him.
+</P>
+
+<P>
+"Wait a minute, Billee!" called Babe into the transmitter. "See
+anything of anybody around there? Anything suspicious?"
+</P>
+
+<P>
+The others could not hear what the old cowboy's answer was, but Babe
+soon enlightened them.
+</P>
+
+<P>
+"He says it's all serene," Babe declared as he now hung up the
+receiver. "Nobody in sight, an' the water is runnin' through the pipe
+as natural as can be."
+</P>
+
+<P>
+"I can't understand it!" declared Bud. "It was almost as dry as a bone
+when we left last night."
+</P>
+
+<P>
+"But it's running in here from the river dam," said Nort.
+</P>
+
+<P>
+"Then there must have been a break somewhere in the tunnel natural
+water course," declared Bud. "Well, if it mended itself so much the
+better. But that doesn't explain this," and he held out the scrawled
+warning. "And if the water stopped once it may stop again."
+</P>
+
+<P>
+"Yes," agreed Babe, "but if anybody wanted to stop it they'd have to do
+it either at this end, where the pipe takes water from the river, or at
+your end, Bud, where it delivers water to your reservoir."
+</P>
+
+<P>
+"Unless somebody stopped the stream inside the tunnel," suggested Dick.
+</P>
+
+<P>
+"Then it would back up here at the river end," said Nort, quickly, "and
+it hasn't done that."
+</P>
+
+<P>
+"No, it hasn't," agreed Bud. "It sure is queer. I'm beginning to
+think there may be more in that black rabbit than I believed first."
+</P>
+
+<P>
+"What rabbit is that?" asked Babe.
+</P>
+
+<P>
+"The one Old Billee said would bring me bad luck," Bud answered.
+"Well," he went on to his cousins, "we might as well go back to camp.
+We can't do anything here."
+</P>
+
+<P>
+"If you've got water that's all you want in Flume Valley," declared
+Babe. "There isn't a finer place t' raise cattle in all th' world than
+there&mdash;if you have <I>water</I>!"
+</P>
+
+<P>
+"And if you haven't&mdash;you might as well quit!" spoke Bud.
+</P>
+
+<P>
+"You eliminated an earful that time," the assistant foreman stated.
+"But I reckon it was just a little break, inside th' tunnel, an' it
+filled itself up natural like. You won't have any more trouble."
+</P>
+
+<P>
+"I hope not," spoke the boy rancher. "Are you going on back to Diamond
+X, Babe?"
+</P>
+
+<P>
+"Not until I find that bunch of strays from Square M. They're too
+valuable t' let slip."
+</P>
+
+<P>
+"Especially to let Hank Fisher, or Del Pinzo, slip them away,"
+exclaimed Bud as he and his chums left the store where they had been
+telephoning.
+</P>
+
+<P>
+"Not so loud! Not so loud!" cautioned Babe.
+</P>
+
+<P>
+"Why not?" Bud wanted to know, when they were outside.
+</P>
+
+<P>
+"'Cause one of Hank's men was in there! He'll be sure t' tell what you
+said, Bud."
+</P>
+
+<P>
+"Let him! I'm not afraid of Hank, or his tool Del Pinzo, and I'd just
+as soon either one would know what I think of 'em!"
+</P>
+
+<P>
+"Don't be too brash; don't be too brash!" counseled Babe. "But they
+sure are both bad actors&mdash;Del an' Hank!"
+</P>
+
+<P>
+There was nothing more that needed to, or could, be done at the Pocut
+River end of the flume, part natural, part artificial, which supplied
+Bud's new ranch with such a vital necessity as water. The stream had
+been dammed just above the intake pipe&mdash;not completely dammed, but
+enough to provide the necessary head of water.
+</P>
+
+<P>
+As Nort had said, had the stream been stopped purposely or by accident
+inside the tunnel, the water would have backed up and run out around
+the pipe, flowing into the river below the dam. But this had not
+occurred.
+</P>
+
+<P>
+"If it doesn't happen again we'll be all right," spoke Bud, as he rode
+back with his cousins, making an easy pace along the trail that led
+over Snake Mountain and down into Flume Valley. "But if the water
+stops running again&mdash;&mdash;"
+</P>
+
+<P>
+"Let's go through the tunnel; it's the only way to be sure!"
+interrupted Nort.
+</P>
+
+<P>
+"I'm with you!" exclaimed Dick.
+</P>
+
+<P>
+"It would seem to be the only way," agreed Bud. "Well, we'll hope this
+is the end of my black-rabbit bad luck, and look for success, now that
+you fellows are here. Cracky! But we'll have some good times, and
+there'll be plenty of work, too!"
+</P>
+
+<P>
+"How many cattle you got?" asked Nort.
+</P>
+
+<P>
+"About five hundred," Bud answered. "Course you have a share with me,
+that your dad bought, but we don't own 'em outright yet. My dad still
+has a mortgage on 'em."
+</P>
+
+<P>
+"But if we have luck we can clear that off; can't we?" asked Dick.
+</P>
+
+<P>
+"Sure, this year, maybe," assented Bud. "I never saw steers fatten so
+fast as ours have since I brought 'em to Flume Valley. I reckon the
+land, being without water so long, raises a specially fine kind of
+grass. Of course, there's always some at the far end of the valley,
+good grass, too, but when there wasn't any water for the cattle to
+drink there wasn't any use trying to raise stock there. But now it's
+different."
+</P>
+
+<P>
+"And all we want is for the water to stay," added Dick.
+</P>
+
+<P>
+"That's all," chimed in his brother.
+</P>
+
+<P>
+With Buck Tooth trailing behind, the three boys took the mountain trail
+and reached their camp near the reservoir that evening. They found Old
+Billee and Yellin' Kid waiting for them, these two cowboys having been
+assigned by Mr. Merkel to help his son in the lad's new venture.
+</P>
+
+<P>
+"Well, yo' got back, I see," remarked Old Billee as he greeted the
+lads, the Indian going off by himself, for he was rather taciturn in
+his manner.
+</P>
+
+<P>
+"Yes, we're here," admitted Bud. "But I can't understand that water
+coming back so unexpectedly."
+</P>
+
+<P>
+"Are you sure it stopped running?" asked Yellin' Kid in his usual loud
+voice.
+</P>
+
+<P>
+"Sure!" declared Bud. "Didn't Buck see it&mdash;or, rather, he didn't see
+it, for there wasn't any water to see coming through the pipe&mdash;only a
+few drops."
+</P>
+
+<P>
+"I wouldn't take his word," declared Old Billee. "Not that Buck would
+actually lie, but those Indians are queer."
+</P>
+
+<P>
+"Oh, we all saw that the water wasn't running," declared Nort.
+</P>
+
+<P>
+"Well, it was when I got here," stated the old cowboy. "And there
+wasn't a sign of anything wrong. But if there had been I'd expected
+it, 'count of&mdash;&mdash;"
+</P>
+
+<P>
+"That black rabbit, I reckon!" broke in Bud.
+</P>
+
+<P>
+"Perzactly!" declared Old Billee. "A black jack shore is bad luck, at
+any stage of the game!"
+</P>
+
+<P>
+But for a time there seemed to be no truth in this western omen.
+Following the first mysterious disappearance of the water, and its
+equally strange reappearance, peace seemed to settle down over Flume
+Valley.
+</P>
+
+<P>
+The steers and yearlings, with which Bud's father had entrusted him and
+the boy ranchers, thrived and fattened on the succulent grass. Old
+Billee, Yellin' Kid, with Buck Tooth's help, aided the boys in such
+minor duties as were necessary to perform about the camp. The main
+duty was looking after the safety of the cattle, to see that none of
+them strayed beyond the wire fence at the far end of the valley.
+Should any stray from the other egress, nearest Diamond X ranch, no
+great harm would result, as they would still be on their owner's land.
+</P>
+
+<P>
+But the farther, or north end, adjoined land owned by Hank Fisher, the
+Double Z representative. And there were ugly stories current
+concerning Mr. Fisher.
+</P>
+
+<P>
+But as the days passed, and as the water still flowed through the pipes
+and underground tunnel into the reservoir, Bud and his companions began
+to think they had imagined more troubles than were really to occur.
+</P>
+
+<P>
+"Guess that warning was only a bluff," said Bud, one day.
+</P>
+
+<P>
+"And the black rabbit doesn't seem to have given you the jinx," added
+Nort.
+</P>
+
+<P>
+"But we didn't find that man you shot," put in Dick.
+</P>
+
+<P>
+"I don't believe I shot him," declared Bud. "There was blood, sure
+enough, but he may have stumbled, as, in fact, we saw him, and
+scratched himself."
+</P>
+
+<P>
+"But where did he disappear to?" asked Nort.
+</P>
+
+<P>
+"Give up," answered Bud. "We'll have to take another look after we get
+our first shipment out of the way."
+</P>
+
+<P>
+For the first bunch of steers from the Flume Valley camp were to be
+disposed of shortly.
+</P>
+
+<P>
+It was the day when this shipment was to be made that Bud, awakening
+early in the tent where he slept with his cousins, uttered an
+exclamation of surprise as he caught sight of something on the blanket
+that covered him.
+</P>
+
+<P>
+"What's the matter?" asked Dick, sitting up.
+</P>
+
+<P>
+"Did you leave this here?" asked Bud, as he held up a piece of board,
+evidently part of a packing case.
+</P>
+
+<P>
+"Me? No!" answered Dick. "What is it?"
+</P>
+
+<P>
+"Either it's a joke, or it's the black rabbit getting in his work,"
+answered Bud. "It's from an unknown enemy&mdash;another warning!"
+</P>
+
+<P>
+And, as Bud held up the board, Nort and Dick could read, scrawled on
+it, evidently with a fire-blackened stick, the words:
+</P>
+
+<P>
+"Warning No. 2. When will you quit?"
+</P>

+TROUBLE AT SQUARE M
+</H3>
+
+<P>
+"Guess that must be a joke," decided Nort, as he stepped gingerly from
+his cot, for it was cold in the mornings, though hot enough at midday.
+"Likely Old Billee or Yellin' Kid stuck it there," added the eastern
+lad, as he looked at the scrawled warning.
+</P>
+
+<P>
+"Old Billee wouldn't do it," declared Bud. "He's gotten over his
+joking days. But it might have been Yellin' Kid."
+</P>
+
+<P>
+"Sure!" agreed Dick. "Probably he did it to make what Billee said
+about the black rabbit come true&mdash;to sort of scare you, Bud."
+</P>
+
+<P>
+"Well, of course that <I>might</I> have happened," admitted the western lad,
+but from the tone of his voice, as he made a hasty toilet, his cousins
+could tell he was far from being convinced.
+</P>
+
+<P>
+"You don't reckon it could be Buck Tooth, do you?" asked Dick,
+following his cousin's example in attiring himself for the day's work.
+</P>
+
+<P>
+"What? That Zuni Indian? I should say not! His idea of a joke would
+make your hair stand on end&mdash;or it would in his wild and younger days.
+Now all he cares about, after he gets through riding herd, is to sit in
+the sun and smoke his Mexican cigarettes. Buck Tooth doesn't joke."
+</P>
+
+<P>
+"Well, maybe it was Yellin' Kid," suggested Nort.
+</P>
+
+<P>
+But when, a little later, they assembled in the meal tent, to partake
+of breakfast, and Bud produced the scrawled board, Yellin' Kid was the
+first to shake his head at the implied question.
+</P>
+
+<P>
+"I like fun!" he remarked in his loud, good-natured voice, "but I don't
+play such jokes as this. My idea of fun would be to help dig up
+another one of them queer, slidin'-trombone insects with the three
+horns that the professor fellers discovered. But this&mdash;why, Bud, this
+may be serious business!"
+</P>
+
+<P>
+"That black rabbit&mdash;I told you!" croaked Old Billee.
+</P>
+
+<P>
+"Do you really think it means anything?" asked the boy rancher, while
+his young partners in the new venture leaned eagerly forward to listen
+to the answer.
+</P>
+
+<P>
+"I sure do," declared Yellin' Kid. "All of us have known, Bud, an'
+your father among 'em, that puttin' a dam in Pocut River, an' taking
+water for you here, at Flume Valley, made the Double Z outfit mad
+enough t' rear up on their hind legs an' howl! Hank Fisher has
+claimed, all along, that th' Diamond X outfit hadn't any right t' take
+water from th' river, t' shunt over on th' other side of Snake
+Mountain, where we are, here."
+</P>
+
+<P>
+"Yes, I heard dad say that," spoke Bud. "But if Hank Fisher had any
+rights that we violated, why didn't he go to law about it?"
+</P>
+
+<P>
+"That isn't Hank's way," commented Yellin' Kid. "He'd more likely try
+some such tricks as <I>that</I>," and the cowboy nodded toward the warning
+on the board.
+</P>
+
+<P>
+"Do you think he left that?" asked Nort.
+</P>
+
+<P>
+"And was he, or Del Pinzo, in our camp last night?" cried Dick.
+</P>
+
+<P>
+"As to that I couldn't say," replied Yellin' Kid. "I slept like two
+tops last night, after I got t' sleep. I didn't even hear you fellows
+<I>snore</I>," he added, for the three boy ranchers had a tent to
+themselves, while Old Billee and Yellin' Kid bunked in an adjoining
+one, Buck Tooth having his own special dugout near the camp fire.
+</P>
+
+<P>
+"We never snore!" declared Nort.
+</P>
+
+<P>
+"Well, I didn't hear a sound!" assented Yellin' Kid.
+</P>
+
+<P>
+"Nor I," said Old Billee.
+</P>
+
+<P>
+There was no use asking Buck Tooth. An actual demonstration would have
+been required to make him understand what a "snore" was, and then he
+might have misinterpreted it into an attempt to work some "magic" on
+him.
+</P>
+
+<P>
+"Well, somebody came in our camp, and left that board&mdash;there's no
+getting away from the fact," declared Bud, as he put aside the ominous
+warning. "And it may have some connection with the stoppage of the
+water, or it may not."
+</P>
+
+<P>
+"I'm inclined t' think it has," said Yellin' Kid. "An', what's more,
+Bud, I think we'll wake up again, some mornin', t' find that reservoir
+of yours out-a business."
+</P>
+
+<P>
+"Do you mean Hank Fisher, or Del Pinzo and his crowd, will blow it up?"
+asked Bud anxiously.
+</P>
+
+<P>
+"Not exactly that, but they'll cut off your water supply."
+</P>
+
+<P>
+"But how can they?" asked Bud. "They can't do anything to the pipe
+intake at Pocut River without being seen, and dad had legal advice to
+the effect that he has as good right to that river water as Double Z,
+or any other ranch. And as for this end of the pipe here, we can look
+after that, I reckon," and he significantly tapped his .45 which he had
+strapped on, preparatory to getting ready for the cattle shipment.
+</P>
+
+<P>
+"That's all right," asserted Yellin' Kid. "But you've forgotten th'
+big tunnel under the mountain, Bud, where the water runs free after it
+leaves the river pipe, an' before it gets to the pipe here."
+</P>
+
+<P>
+"But Hank, or Del Pinzo, can't cut off the water inside the mountain
+tunnel without having it back up and run into the river again&mdash;and it
+didn't do that!" Bud insisted.
+</P>
+
+<P>
+Yellin' Kid shrugged his shoulders, as he started for the corral to get
+his horse, since he was to aid in driving the cattle to the railroad
+stock yard.
+</P>
+
+<P>
+"I don't know nothin' about th' scientific end of it," he drawled
+loudly, "but, mark my words, there's some queer business goin' on, an'
+Hank Fisher an' Del Pinzo have a hand in it. Look out for your water
+supply, Bud; that's my advice!"
+</P>
+
+<P>
+"An' don't let any more black rabbits cross your path," added Old
+Billee.
+</P>
+
+<P>
+"Bunk!" scoffed Bud. "Though I don't like this warning, all the same.
+Let's go take a look at the reservoir, fellows."
+</P>
+
+<P>
+But an inspection of the concrete water-container showed nothing wrong
+there. The sparkling fluid, so necessary for the cattle, and so vital
+to Diamond X Second, was spurting from the pipe freely.
+</P>
+
+<P>
+"Guess they're only trying to bluff us!" was Dick's opinion.
+</P>
+
+<P>
+"Maybe," assented his cousin. "But, all the same, I'd like to know who
+was in our camp last night. If this thing is going to keep up we'll
+have to mount guard."
+</P>
+
+<P>
+"That wouldn't be a bad idea," declared Nort. "I don't like to go to
+bed so early, anyhow."
+</P>
+
+<P>
+"You'll be glad enough to turn in after we get into the swing of things
+here, branding cattle, shipping 'em off and all that," said Bud. "But
+let's take a look around after we get this bunch off."
+</P>
+
+<P>
+And when Yellin' Kid, with another cowboy sent by Mr. Merkel to help
+Bud in getting the steers to the railroad station, had departed with
+the shipment, the boy ranchers, Old Billee and Buck Tooth made a
+careful examination in the vicinity of the tents.
+</P>
+
+<P>
+Of course, with so many who really belonged in the camp, tramping
+around it, there was little likelihood of an alien foot being
+discovered. Nevertheless, Bud hoped for something of this sort. But
+it was not to be. No trace of the midnight intruder, who had left the
+ominous warning, was discovered. And yet he had come and gone&mdash;had
+even penetrated to the tent where the boys were sleeping.
+</P>
+
+<P>
+"It's either bluff, or it means something," declared Bud, as they
+assembled for lunch. "And if it isn't bluff, but a <I>fight</I>, Hank
+Fisher and Del Pinzo will find we can stick to our guns as well as
+they!"
+</P>
+
+<P>
+"You said it!" cried Nort.
+</P>
+
+<P>
+"Del Pinzo didn't stay long in jail; did he?" asked Dick, for,
+following the discovery of the Triceratops and the capture of the
+cattle rustlers, as detailed in the first volume, the Mexican halfbreed
+had been arrested.
+</P>
+
+<P>
+"No, he managed to get out, and, by some hook or crook, he still
+manages to escape arrest," Bud answered.
+</P>
+
+<P>
+For some time it appeared that the two warnings were only "bluffs." No
+sign came from the unknown, and no trace was seen of Hank Fisher, Del
+Pinzo or any of the unprincipled gang which had made so much trouble
+the previous year for the Diamond X outfit.
+</P>
+
+<P>
+Nor did the water coming under Snake Mountain show any signs of giving
+out. Day after day it ran its limpid stream, furnishing drink for man
+and beast, and enabling grass to grow where it had never grown before.
+</P>
+
+<P>
+"Some day I'm going to rig up a turbine wheel and attach a dynamo to
+it, so we can have electric light here," declared Bud.
+</P>
+
+<P>
+"That'll be great!" exclaimed Dick.
+</P>
+
+<P>
+The first shipment of cattle had been safely gotten off from Flume
+Valley, and brought a good price. This money did not all come to the
+boy ranchers, however, as Mr. Merkel had insisted on a strict business
+deal; and he was to be paid for his share of the stock he supplied Bud
+from the first money coming in. Later the boys would get their
+profits&mdash;if there were any.
+</P>
+
+<P>
+But the first lot of steers had been sent away, bringing a higher price
+than usual because of their prime condition, attributed, so Bud said,
+to the finer quality of grass, and it looked as if the boy ranchers
+might make a success of their first venture.
+</P>
+
+<P>
+"Even discounting the black rabbit and the warnings out of the air,"
+said Bud.
+</P>
+
+<P>
+It was, then, with somewhat of an ominous feeling that, one morning, as
+the boys and their cowboy friends were at breakfast, they saw a rider
+hastening toward them along the trail that led from Diamond X.
+</P>
+
+<P>
+"It's Snake Purdee!" exclaimed Yellin' Kid, when the rider had
+approached near enough to be recognized.
+</P>
+
+<P>
+"An' he's ridin' like he had suthin' on his mind!" added Old Billee.
+"I hope that black rabbit&mdash;&mdash;" he murmured, and then his voice trailed
+off into a whisper as Yellin' Kid surreptitiously kicked him under the
+packing-box table.
+</P>
+
+<P>
+"Don't scare th' boys!" whispered Yellin' Kid in explanation, as Snake
+Purdee galloped nearer.
+</P>
+
+<P>
+The rider flung himself from his pony, which came to a sliding stop
+near the camp tents, and, looking first at the boy ranchers, and then
+at the big, peaceful valley stretching out before him, remarked:
+</P>
+
+<P>
+"Yes, there's plenty of room here!"
+</P>
+
+<P>
+"For what?" asked Bud.
+</P>
+
+<P>
+"More cattle!" answered Snake Purdee. "There's been trouble over at
+Square M, fellows!"
+</P>
+
+<P>
+"Trouble?" exclaimed the boy ranchers in chorus. "What kind?"
+</P>
+
+<P>
+"Bad trouble," was the reply. "Call your father up on th' 'phone,
+Bud," he added. "He wants t' talk t' you. Yes," he went on, musingly,
+as Bud hastened in to the telephone, "there's bad trouble at Square M!"

+
+<P>
+Nort and Dick looked at each other as Bud slipped into the tent where
+the telephone had been installed. Snake Purdee strode over to the
+water pail, and took a long drink.
+</P>
+
+<P>
+"That's good stuff!" he remarked with a sigh of satisfaction, and then
+he led his pony to the trough, into which the thirsty animal dipped his
+muzzle deeply. "Mighty good water!"
+</P>
+
+<P>
+"An' I hope nothing happens to it," voiced Old Billee.
+</P>
+
+<P>
+"Happens! What d'yo' mean?" questioned the bearer of bad tidings.
+"The water's here, ain't it?"
+</P>
+
+<P>
+"But no tellin' how long it'll run," added the veteran cowpuncher. "A
+black rabbit run across Bud's path the day he was ridin' to meet Nort
+and Dick, and ever since then&mdash;&mdash;"
+</P>
+
+<P>
+"Do you mean t' tell me you still believe in that old superstition?"
+laughed Snake Purdee, who had acquired this name because of his
+exceeding fear of rattlers and other reptiles. He had been bitten
+once, he declared, and had nearly died.
+</P>
+
+<P>
+"There's more'n superstition!" declared Old Billee. "Look at that!"
+and he brought out the board warning, and related the incident of the
+mysterious disappearance of the water, and its equally strange
+reappearance.
+</P>
+
+<P>
+"Oh, it's just one of those freaks of the old, underground river
+course," said Snake. "Of course I wouldn't put much past Hank Fisher
+and Del Pinzo, but if either of them sent these warnings it was t' play
+a joke, an' scare our boy ranchers. Guess Hank's jealous!" laughed
+Snake.
+</P>
+
+<P>
+"But what has happened over at Square M?" asked Dick.
+</P>
+
+<P>
+"Has Hank or Del Pinzo anything to do with that?" Nort wanted to know.
+</P>
+
+<P>
+"I don't see how they could," spoke Snake. "It's just that&mdash;&mdash;"
+</P>
+
+<P>
+But at this moment Bud came out of the tent, having finished his
+telephonic talk with his father.
+</P>
+
+<P>
+"There's an epidemic of disease at dad's Square M ranch," Bud explained
+to his cousins and the others. "It's so bad that a lot of the steers
+have already died, and dad is going to take off the rest of the stock
+before they catch the trouble. Some he's going to put at Triangle B,
+some at Diamond X and some he's going to haze over to us. We'll have
+to double up, fellows," he told Nort and Dick. "I guess dad is glad
+he's got Flume Valley now. It may save him a lot of money that
+otherwise he'd lose."
+</P>
+
+<P>
+"Got t' double up, eh?" murmured Old Billee Dobb. "How many head's he
+goin' t' send here, Bud?"
+</P>
+
+<P>
+"About five hundred he told me. They'll be stock that hasn't been near
+the infected cattle," he went on, "so there won't be any danger to our
+herds."
+</P>
+
+<P>
+"Can we look after five hundred more steers?" asked Nort.
+</P>
+
+<P>
+"Oh, I'm comin' to help you," offered Snake. "I forgot t' say that I
+was going t' move into one of your <I>flats</I>," and he waved his hand
+toward where the white tents made an attractive camp. "Didn't bring my
+duffle bag," he added, "but one of th' boys is going t' ride over this
+evening with his 'n' mine."
+</P>
+
+<P>
+"Is some one else coming?" Bud wanted to know. "If we double up too
+much we'll need more grub."
+</P>
+
+<P>
+"Your dad told me t' tell you he'd send some," went on Snake. "Yep, a
+new ranch hand is due t' arrive this evenin'. He's a wonder with th'
+gun an' rope, t' hear him tell it!" chuckled Snake.
+</P>
+
+<P>
+"One of them fly boys?" asked Old Billee, mildly, with a gleam of light
+in his eyes, however. "Will his heels need clippin', Snake?"
+</P>
+
+<P>
+"Might," was the brief answer. "But now you know th' worst. There's
+trouble at Square M, an' you'll have to double up with cow punchers an'
+stock, Bud."
+</P>
+
+<P>
+"I don't mind," said the boy rancher. "Dad says he'll split the
+profits with me, and that's what we're looking for&mdash;to make a success
+of Flume Valley ranch. We'll do it, too!" he asserted confidently.
+</P>
+
+<P>
+"If th' water holds out, an' no more black rabbits don't throw you,"
+murmured Old Billee Dobb.
+</P>
+
+<P>
+"Shucks!" laughed Bud, but the day was to come when he recalled the old
+cowboy's ominous warning.
+</P>
+
+<P>
+"It's queer, though," said Bud that evening, when they were gathered
+around the camp fire, discussing the coming of the cattle from Square
+M, which were to arrive the following day, or the one after that.
+"It's queer what made that disease break out so suddenly among dad's
+steers. There aren't any cases of it at Double Z; are there?" he asked
+Snake. "And Fisher's place is the next one nearest ours."
+</P>
+
+<P>
+"No, I don't recall hearin' that Hank's stock is sufferin' any," the
+cowboy admitted. "But Square M is hard hit. It's a disease the
+government experts are tryin' t' find a remedy for. Been experimentin'
+with all sorts of serums, germs an' th' like, I understand."
+</P>
+
+<P>
+"Is it a germ disease?" asked Nort.
+</P>
+
+<P>
+"That's what they call it," the cowboy asserted. "It can be given
+easy, from one steer to another, just by rubbin' horns, so t' speak.
+Or the trouble may break out sudden in a herd, if th' germ gets loose
+in 'em."
+</P>
+
+<P>
+"That's all bosh!" declared Pocut Pete, the new cowboy who had arrived
+just about grub time, with his own outfit and that of Snake Purdee, who
+had ridden over "light."
+</P>
+
+<P>
+"What's bosh?" asked Old Billee.
+</P>
+
+<P>
+"The idea that this disease is spread by germs, or 'bugs,' as some
+folks call 'em. I think the cattle get poisoned by eating some weed,
+same as lots of 'em get locoed."
+</P>
+
+<P>
+"Well, maybe," agreed Bud. "Anyhow, we got good feed here, and plenty
+of water for dad's cattle, as well as ours. We can double up as well
+as not. Now I wonder if we have blankets enough for you two?" and he
+looked at Snake and Pocut, who said his name had been given him as he
+had "punched" cows so long in the vicinity of the Pocut River.
+</P>
+
+<P>
+"Oh, we'll make out," asserted Snake, who was easily suited.
+</P>
+
+<P>
+But Bud, being the nominal head of the camp, would leave nothing to
+chance. While some of the others were still about the flickering camp
+fire, talking of the trouble at Square M, the strange disappearance of
+the water and kindred topics, the boy rancher went to inspect the tent
+where the older cowboys were to pass the night.
+</P>
+
+<P>
+It was fitted with cots enough, and one to spare, but Bud wanted to
+make sure of the blankets. For it gets cold at night on the western
+plains on even very hot days.
+</P>
+
+<P>
+As Bud entered the tent he saw, in the dim light of a turned-down
+lantern, a figure sitting on one of the cots.
+</P>
+
+<P>
+"That you, Snake?" Bud asked.
+</P>
+
+<P>
+"No, it's me," answered the voice of the new cowboy, Pocut Pete.
+</P>
+
+<P>
+"Oh," remarked the lad, and as the other arose Bud caught the tinkle of
+glass. For a moment an ugly suspicion entered Bud's mind, but when his
+nostrils did not catch the smell of liquor, which was strictly
+forbidden on all Mr. Merkel's ranches, Bud felt a sense of relief.
+</P>
+
+<P>
+Pocut Pete passed out, after Bud had assured himself that there were
+blankets enough, and as the boy rancher was leaving the tent, he trod
+on something that broke, with a grating sound, under his foot.

+<H3 ALIGN="center">
+DRY AGAIN
+</H3>
+
+<P>
+"What the mischief's that?" exclaimed Bud, as he unhooked the lantern
+from the tent pole and swung it toward the ground where he had set his
+foot. "Has Nort or Dick lost their bottle of paregoric?" and he
+chuckled as he recalled what use his cousins had made of that
+baby-pacifier when they had been captured at the camp of the
+professors, as related in the book prior to this.
+</P>
+
+<P>
+"It <I>is</I> a bottle, and I stepped on it and smashed it," went on Bud, as
+he saw the shining particles of thin glass. "That new cowboy, Pocut
+Pete, must have dropped it. Hope it wasn't any medicine he needed.
+Smells mighty queer, though!" and Bud sniffed the air. "I hope he
+isn't one of those 'dope fiends,'" and again a feeling of apprehension
+passed over him.
+</P>
+
+<P>
+Bud picked up one of the largest pieces of the crushed glass bottle.
+The little phial appeared to have been filled with a sticky, yellowish
+substance, and the odor was not pleasant.
+</P>
+
+<P>
+"Whew!" exclaimed Bud as he caught a strong whiff of it. "I wouldn't
+want to have to take any of <I>that</I> for medicine. Guess I'll ask Snake
+what he knows of Pocut Pete before I make any inquiries on my own hook.
+And I'll tell him he'd better bury this glass if he doesn't want to cut
+his own feet, or that of the others."
+</P>
+
+<P>
+"Bunks all right?" asked Old Billee Dobb, as Bud emerged from the tent.
+</P>
+
+<P>
+"All ready to turn in," was the answer.
+</P>
+
+<P>
+"Which I'm going to do dark an' early," declared the old cowboy. "I
+have the late watch t'-night."
+</P>
+
+<P>
+For it had been decided, with the coming of the additional steers from
+Square M, that it would be necessary to ride herd, as so many cattle in
+a bunch might engender a stampede. And at Old Billee's suggestion the
+night-riding was to start then, to break them in, so to speak.
+</P>
+
+<P>
+Bud saw Pocut Pete standing by himself at the cook tent, Buck Tooth
+having been induced to open some cans of peaches, a form of fruit much
+in favor on western ranches where the fresh variety is unobtainable.
+</P>
+
+<P>
+"You'd better clean up that glass you left in the bunk tent," Bud
+remarked in a low voice.
+</P>
+
+<P>
+"What glass?" sharply demanded the other, and there was in his voice a
+note of defiance, the boy thought.
+</P>
+
+<P>
+"The glass bottle you dropped, and I stepped on," Bud resumed, for he
+did not hesitate to give orders in his own camp.
+</P>
+
+<P>
+"I didn't drop any bottle!" declared Pocut Pete.
+</P>
+
+<P>
+"Well, some one did, and I smashed it," asserted Bud. "If you don't
+want to cut your feet you'd better bury it," and he hurried off to wash
+from his hands some of the unpleasant-smelling mixture that had clung
+to them.
+</P>
+
+<P>
+"I sleep with my boots on," said Pocut Pete. "But I'll tell the rest
+of 'em to be careful."
+</P>
+
+<P>
+"It would be better," Bud flung back over his shoulder.
+</P>
+
+<P>
+It was late next day when cowboys from Square M arrived, slowly driving
+before them the cattle that were to be doubled up with those which Bud,
+Nort and Dick considered specially their own.
+</P>
+
+<P>
+"What's the situation over there now?" Bud asked one of the punchers,
+who looked tired and weary, for the trail had been long and dry, as
+evidenced by the eager manner in which the steers rushed for water.
+</P>
+
+<P>
+"Pretty bad," was the answer. "This disease, whatever it is, seems to
+kill off mighty quick. I don't know how many your dad has lost, but I
+guess now, what with those we've brought here and them sent to Diamond
+X and Triangle B, that we'll get the best of the trouble. Gosh! You
+got a nice place here!" he added admiringly.
+</P>
+
+<P>
+"Yes, it's pretty good," Bud agreed. "Bringing the water over from
+Pocut River made all the difference in the world."
+</P>
+
+<P>
+"You got out a lungful that time!" asserted another of the cowboys who
+had helped "haze" over the steers that were transferred to save them
+from infection.
+</P>
+
+<P>
+The visiting cowboys departed next day, leaving their animals mingled
+with those in which Bud, Nort and Dick had an interest. The doubled-up
+herd was not too large but what there was plenty of feed and water in
+Flume Valley.
+</P>
+
+<P>
+During the days that followed, matters at Diamond X Second, as Bud
+sometimes called his ranch camp, adjusted themselves smoothly. There
+was no further sign, or evidence, of mysterious warnings. The cattle
+throve, and those from Square M, which were not in as good physical
+condition as the animals that had been longer in the green valley,
+began to "pick up" and fatten.
+</P>
+
+<P>
+"I tell you what, fellows!" boasted Bud to his cousins, "dad'll be
+wishing he'd kept this ranch for himself! We'll beat him at his own
+game!"
+</P>
+
+<P>
+"It would be a big stunt if we could, not taking advantage of his bad
+luck at Square M, though," spoke Nort.
+</P>
+
+<P>
+"Well, you have to count on bad luck in this business," remarked Bud.
+"Not that black rabbits have anything to do with it," he laughed, as he
+looked at Old Billee.
+</P>
+
+<P>
+Bud and his cousins were returning, one hot afternoon, from having
+ridden to a distant part of the valley, where Snake Purdee had reported
+he had found a calf killed. There was a suspicion that rustlers had
+been at work, but Bud decided the animal had been separated from its
+mother and the main herd, and had been pulled down by coyotes.
+</P>
+
+<P>
+"What's that?" asked Nort, when they were within sight of the camp with
+its reservoir in the background.
+</P>
+
+<P>
+"What's what?" asked Bud, who pulled his pony aside quickly, to escape
+a prairie dog's burrow.
+</P>
+
+<P>
+"Looks like Old Billee waving his hat for us to hit up the pace," spoke
+Dick.
+</P>
+
+<P>
+"It is!" asserted Bud, after gazing beneath his hands held in front of
+his eyes as a sun-shield. "I hope nothing's wrong!"
+</P>
+
+<P>
+But when they had ridden up, the old cowboy riding out to meet them, it
+was made plain, in a moment, that something had occurred out of the
+ordinary.
+</P>
+
+<P>
+Old Billee Dobb was much excited. His eyes blazed and snapped and he
+shook the reins in addition to mildly spurring on his pony.
+</P>
+
+<P>
+"More mysterious warnings?" asked Bud.
+</P>
+
+<P>
+"Worse'n that," was the answer. "She's dry ag'in!"
+</P>
+
+<P>
+"The pipe line?" asked Dick.
+</P>
+
+<P>
+"You hit it!" cried the other. "Water's stopped runnin' ag'in, Bud!"
+</P>
+
+<P>
+"Whew!" whistled the boy rancher. "And with a double lot of stock on
+hand, too! This <I>is</I> bad!"

+<H3 ALIGN="center">
+A SHOT IN THE NIGHT
+</H3>
+
+<P>
+Wheeling his pony, Old Billee rode back with the boy ranchers, until
+they reached the bottom of the reservoir wall. Then, dismounting, Bud,
+Nort and Dick scrambled up the earth slope on one side until they could
+look into the storage tank, and at the pipe which, connecting with the
+old underground water-course, kept the reservoir filled.
+</P>
+
+<P>
+"She isn't spouting!" said Bud, in blank disappointment.
+</P>
+
+<P>
+"Just a dribble," added Nort, mournfully.
+</P>
+
+<P>
+"And if it does as it did before that'll stop in a little while,"
+remarked Dick.
+</P>
+
+<P>
+"When did it start to stop?" asked Bud, unconscious of the double
+meaning of his words.
+</P>
+
+<P>
+"About an hour ago," Old Billee answered. "I happened t' notice it
+when I come up here t' try for a fish."
+</P>
+
+<P>
+"Fish!" cried Nort. "Can you get any fish <I>here</I>?"
+</P>
+
+<P>
+"Sartin sure!" asserted the old cowboy. "They come in from th' river,
+under th' mountain, though how they like the dark I can't say, an' they
+come out of this pipe. I've caught many a good one."
+</P>
+
+<P>
+The eastern lads looked to Bud for confirmation, and their cousin,
+nodded, rather gloomily, though.
+</P>
+
+<P>
+"Yes," said Bud, "fish do come through the pipe. But if we don't get
+any more water they'll all die off soon."
+</P>
+
+<P>
+"Maybe the water will come back&mdash;as it did before," asserted Dick.
+</P>
+
+<P>
+Bud did not answer. He appeared to be figuring out something on the
+back of an old envelope with the stub of a pencil.
+</P>
+
+<P>
+"We'll have enough for a week, I think," finally announced the boy
+rancher. "Then, if the water doesn't come back, we'll have to drive
+all the stock over to Diamond X. Can't take a chance letting 'em die
+of thirst here, even if they didn't stampede, which they'd be sure to
+do."
+</P>
+
+<P>
+Two things are vitally necessary on a ranch&mdash;grass and water for the
+stock. Of grass there was plenty in Flume Valley, and, had the stream
+continued to come through the pipe, there would have been a goodly
+supply of water, even for the extra stock added from Square M.
+</P>
+
+<P>
+But when no fluid spurted from the mouth of the black pipe, the other
+end being hidden in the opening of the natural water course, it spelled
+ruin for Diamond X Second.
+</P>
+
+<P>
+"I wonder&mdash;I just wonder&mdash;if this has anything to do with the threat we
+received?" mused Bud, as he and his cousins went down the slope to the
+little table of land where the tents were pitched.
+</P>
+
+<P>
+"Granting that it has, who sent the warning?" asked Nort.
+</P>
+
+<P>
+"Who else but the man who doesn't want to see any water diverted from
+Pocut River?" asked Bud, in turn. "I mean Hank Fisher, and the gang he
+trails along with! If anyone stopped this water, he did!"
+</P>
+
+<P>
+"But how?" asked Yellin' Kid, who had strolled up to take part in the
+general conversation. "He couldn't do it at th' river end of th' pipe,
+without bein' found out, and he hasn't been around <I>here</I>, I'll gamble
+on that&mdash;not since we started keepin' watch at night."
+</P>
+
+<P>
+"No, he hasn't been here," admitted Bud, slowly. "It sure is a puzzle.
+Well, let's have grub, and talk about it later. It may come back. If
+it doesn't we have enough for a week&mdash;maybe longer."
+</P>
+
+<P>
+It was drinking water for the cattle that was mostly needed, since the
+occasional, slight rainfall was now sufficient to provide for the
+grass, though some water was used to irrigate certain sections that
+would be called "meadows" in the east. This drinking water was
+conducted to distant troughs by pipes running from the reservoir, the
+pipes being controlled by means of valves, or water gates.
+</P>
+
+<P>
+Had there been natural water-holes in Flume Valley it would, long ago,
+have been used as a place to raise cattle. But it was the absence of
+drinking places that caused it to be passed by, until, by artificial
+means, tapping the river through the underground course, Mr. Merkel had
+enabled his son and nephews to become boy ranchers in earnest.
+</P>
+
+<P>
+As Bud had stated, there was about a week's supply on reserve in the
+concrete reservoir. When that was exhausted, unless the water again
+started flowing through the pipe, the cattle would suffer from thirst.
+</P>
+
+<P>
+"Well, she isn't spouting any," mournfully remarked Nort, as, with his
+brother and Bud, he ascended the slope, standing on the edge of the
+reservoir.
+</P>
+
+<P>
+"No," agreed Bud. "She's as dry as an old buffalo skull now. I don't
+know what to do!"
+</P>
+
+<P>
+The shadows of dusk were falling, and the boys felt that the night was
+coming with its gloom to match their own feelings. Failure seemed to
+stare them in the face.
+</P>
+
+<P>
+"But I don't see how anyone&mdash;granting that somebody like Hank Fisher or
+Del Pinzo has it in for us&mdash;can shut off the water without operating at
+either end of the flume!" exclaimed Nort.
+</P>
+
+<P>
+"That is queer," agreed Bud. "I wonder what's inside that tunnel where
+the old watercourse runs? I've been through it, but couldn't see much
+of anything. I've a good notion&mdash;&mdash;"
+</P>
+
+<P>
+He broke off his remarks to gaze intently ahead. There was a movement
+in the gloom, and a figure walked away.
+</P>
+
+<P>
+"Who's there?" asked Bud sharply, his hand slipping to his .45.
+</P>
+
+<P>
+"It's me," came quickly, if not grammatically, from Pocut Pete, whose
+voice the boys recognized. "I just moseyed up here t' see if she was
+runnin'."
+</P>
+
+<P>
+"Well, she isn't," spoke Bud, a bit shortly.
+</P>
+
+<P>
+"So I see," came the drawling answer, and it was followed by a faint
+tinkling of glass.
+</P>
+
+<P>
+Bud started, and tried to pierce the night shadows. But all he saw was
+the figure of the strange cowboy becoming more and more indistinct.
+Bud was just going to say something when he was halted by the voice of
+Nort.
+</P>
+
+<P>
+"I have an idea!" exclaimed the eastern lad.
+</P>
+
+<P>
+"What is it?" asked his brother. "Anything to do with this?" and he
+waved toward the reservoir which was strangely still, now that the
+water no longer bubbled into it from the pipe.
+</P>
+
+<P>
+"Yes," went on Nort. "Why not investigate and see where the stoppage
+is, Bud?"
+</P>
+
+<P>
+"Investigate what?"
+</P>
+
+<P>
+"The pipe line&mdash;the old underground water-course."
+</P>
+
+<P>
+"You mean go through the tunnel?" Bud asked.
+</P>
+
+<P>
+"Sure! Why not? You say it's big enough all the way through, and the
+water itself doesn't occupy much of the bottom. We could walk it in a
+day, easy!"
+</P>
+
+<P>
+"Yes," agreed Bud, "it isn't more than five miles, though we'd have to
+carry lanterns, and we might get lost in some side passage."
+</P>
+
+<P>
+"That's just what I want to find out about!" cried Nort. "If there
+<I>is</I> a branch passage maybe that's where the water goes! Come on, Bud,
+let's go through the tunnel!"
+</P>
+
+<P>
+"I'm with you!" said Dick.
+</P>
+
+<P>
+For a moment Bud hesitated and then, as he was about to reply, there
+came the sudden sound of a shot, which shattered the night with a
+sliver of flame, plainly visible to the boys.
+</P>
+
+<P>
+Instantly a band of coyotes set up their weird howling, and the
+startled steers lowed and bellowed as they rushed about.

+INTO THE TUNNEL
+</H3>
+
+<P>
+"What's that?" cried Bud.
+</P>
+
+<P>
+"Who's there?" demanded Nort.
+</P>
+
+<P>
+The hand of Dick went toward the .45 he wore in a holster at his belt,
+and, it might be added, the hands of the others did also.
+</P>
+
+<P>
+"Keep your shirts on," came the somewhat drawling voice of Pocut Pete,
+who, it seemed, had returned after shuffling off in the darkness. "I
+just winged a coyote."
+</P>
+
+<P>
+"Oh," murmured Bud. "You were shooting at them, were you?" he asked.
+</P>
+
+<P>
+"Not exactly," answered Pocut Pete, as he sauntered up out of the
+gloom. "I saw something movin' down among th' cattle, an' I knew it
+couldn't be any of you fellows, so I let go at him."
+</P>
+
+<P>
+"<I>Him!</I>" cried Nort. "Was it a man?"
+</P>
+
+<P>
+"Looked like one," drawled Pete. "I heard you'd had trouble with
+rustlers before I came, so I wasn't takin' any chances. I didn't aim
+t' hit him, though, only t' scare him, an' I must have winged one of
+them night-owls!" He chuckled at this characterization of the coyotes.
+</P>
+
+<P>
+"Let's take a look down there," suggested Bud to his cousins, their
+worried interest in the stoppage of the water momentarily eclipsed by
+the new excitement.
+</P>
+
+<P>
+"Oh, you won't find anyone down there <I>now</I>!" Pocut Pete made haste to
+say. "If it was a rustler he's far enough off by <I>this</I> time, an' I'm
+not positive I really saw one&mdash;it was so dark."
+</P>
+
+<P>
+"It won't do any harm to take a look," declared Bud, and his cousins
+were of the same opinion.
+</P>
+
+<P>
+"Suit yourself," spoke Pete, easily. "If I did hit him let me know."
+</P>
+
+<P>
+Again he moved off in the darkness, and the boy ranchers, after a
+moment of hesitation, started in the direction whence the shot had been
+heard and the sliver of flame seen. Pocut Pete had gone on the
+opposite trail after returning to the boys, a fact which caused Dick to
+remark:
+</P>
+
+<P>
+"Wouldn't you think he'd want to see if he did wing anybody?"
+</P>
+
+<P>
+"He knows well enough he didn't," declared Bud in a low voice, for he
+and the others realized that sounds, especially voices, carried almost
+as clearly in the night air as across a body of water.
+</P>
+
+<P>
+"What made him talk that way then?" asked Nort.
+</P>
+
+<P>
+"Oh, he's&mdash;queer, I guess," replied Bud. "I don't exactly just like
+the way he acts. Did you fellows hear the tinkle of glass just before
+that shot?"
+</P>
+
+<P>
+"I did," answered Nort, but Dick was not so sure. "What do you make of
+it?" Nort wanted to know.
+</P>
+
+<P>
+"Wish I knew," spoke Bud, and then he told them about having found the
+small, thin, broken phial of dubious-smelling mixture in the bunk tent
+of the older cowboys.
+</P>
+
+<P>
+"Do you think he takes 'dope,' or medicine of some sort?" asked Dick.
+</P>
+
+<P>
+"It's hard to say," was Bud's reply. "But let's look around and see
+what we can find."
+</P>
+
+<P>
+Their search was unrewarded, however. The cattle quieted down after
+the shot, and the coyotes only occasionally gave vent to their
+blood-curdling yells. But as for finding anyone who had been
+shot&mdash;including even a miserable coyote&mdash;there was not a sign.
+</P>
+
+<P>
+"Guess Pete didn't wing anybody after all," mused Dick, as he and his
+chums turned back toward the camp.
+</P>
+
+<P>
+"I never s'posed he did," grunted Bud. "He's a four-flusher, that
+fellow is, in my opinion. I wish dad had sent me somebody else."
+</P>
+
+<P>
+"He's a good cowboy," defended Nort.
+</P>
+
+<P>
+"Yes, but I don't feel that I can trust him. I'd rather have one like
+Old Billee, slow as he is, than two Pocut Pete chaps," grumbled the boy
+rancher. "But we've got other worries besides him, fellows! What are
+we going to do for water, now that we have a double supply of cattle at
+our ranch? That's what's worrying me!"
+</P>
+
+<P>
+"It's enough to worry anyone," Dick agreed. "Maybe the water will come
+back, Bud."
+</P>
+
+<P>
+"I hope it does," added Nort.
+</P>
+
+<P>
+"We'll take a stroll through that tunnel&mdash;it's the only way to find out
+what's wrong," decided Bud. "Talk about black rabbits! I begin to
+think Old Billee was more right than wrong!"
+</P>
+
+<P>
+"But your bad luck, so far, isn't as bad as your father's in losing
+cattle from disease," remarked Nort.
+</P>
+
+<P>
+"No, and I hope that the epidemic doesn't break out here at Diamond X
+Second," went on Bud. "If it starts, and we don't get the water back,
+we may as well give up!"
+</P>
+
+<P>
+He was plainly discouraged, and no wonder. He was young, and it was
+his first experience as a rancher "on his own." Nort and Dick, too,
+were a little down-hearted.
+</P>
+
+<P>
+"But maybe things will look better to-morrow," suggested Nort, as they
+turned in for the night, having discovered nothing alarming in the
+direction where Pocut Pete had shot.
+</P>
+
+<P>
+"Maybe," half-heartedly assented Bud.
+</P>
+
+<P>
+But there was no water coming through the reservoir end of the tunnel
+pipe when the sun shone again, and, after breakfast, the boy ranchers
+prepared to explore the dark cave-like opening which extended under the
+mountain.
+</P>
+
+<P>
+"I hope we can turn it on," said Bud, and he looked at the concrete
+basin of water, trying to calculate how much longer it would last if
+the supply were not replenished. Already it was lower than it had been
+the night before, for the cattle had drunk freely during the darkness.
+</P>
+
+<P>
+Lanterns were gotten ready, a supply of grub packed, weapons were
+looked to (for who knew what beast might not lurk in the tunnel?) and
+at last the boy ranchers were ready to start.
+</P>
+
+<P>
+"Good luck!" wished Yellin' Kid as the little party started for the
+mouth of the tunnel.
+</P>
+
+<P>
+"Thanks," chorused Nort, Dick and Bud.
+</P>
+
+<P>
+Then they entered the black opening.
+</P>
+
+<P>
+If you will imagine a hillside, with a hole, or tunnel, about ten feet
+high and as broad, but of irregular shape, opening into it, and on the
+bottom, or floor, a two-foot iron pipe out of which, at normal times,
+ran a stream of water, you will have a good idea of the place into
+which our young heroes were to enter.
+</P>
+
+<P>
+The tunnel extended all the way through Snake Mountain, curving this
+way and that, as a brook curves its way through a meadow. In fact the
+tunnel had been made, centuries ago, by a stream forcing its way
+through the soft parts of the mountain, and it was this old, hidden,
+underground stream-way of which Mr. Merkel had taken advantage to bring
+water to Flume Valley.
+</P>
+
+<P>
+The stream flowed along the bottom of the tunnel course, leaving room
+on either side for persons to walk, as they might walk along the banks
+of a stream in the open. The underground river was not more than four
+feet wide, and about the same in average depth, but in places it flowed
+with a very powerful current.
+</P>
+
+<P>
+"Whew! It's black as tar here!" exclaimed Dick, as they walked in past
+the pipe, and found themselves in the tunnel proper.
+</P>
+
+<P>
+"As bad as the Hole of Calcutta," added Nort, who had read that grim
+story of the Sepoy rebellion in India.
+</P>
+
+<P>
+"Do you want to back out?" asked Bud, swinging his lantern so that it
+cast flickering shadows on the place where water had flowed, but where
+there was none now.
+</P>
+
+<P>
+"Back out!" cried Nort. "I should say not! Lead on, Macduff!"
+</P>
+
+<P>
+And they started off in the blackness of the tunnel, with only the
+faint gleams of the lanterns to illuminate their way. What would they
+find?

+<H3 ALIGN="center">
+THE RUSH OF WATERS
+</H3>
+
+<P>
+Echoes of the footsteps of the boy ranchers sounded and resounded as
+they tramped along the now dry water-course of what had, only a day
+before, been a life-giving stream of water. The rocky and
+roughly-vaulted roof overhead gave back the noises like the soundbox of
+a phonograph, and the lads had to speak loudly, in places, to make
+their voices carry above the echoes. These places were spots where the
+vaulted roof of the tunnel was higher than usual.
+</P>
+
+<P>
+They had walked on, the semi-circular spot of light at the entrance
+near the black pipe growing more and more faint, until it was not at
+all visible.
+</P>
+
+<P>
+"There she goes!" exclaimed Dick, looking back.
+</P>
+
+<P>
+"What?" asked his brother.
+</P>
+
+<P>
+"The last gleam of daylight," was the answer. "If anything happens to
+our lanterns, so that they go out, and we get mixed up in some branch
+passages&mdash;good night! That's all I have to say!" and Dick was very
+emphatic in this.
+</P>
+
+<P>
+"By Zip Foster!" exclaimed Bud, using that expression for the first
+time in several days. "You're a cheerful chap to have along on a
+picnic like this, Dick! Not!"
+</P>
+
+<P>
+"Well, might as well prepare for the worst and hope for the best,"
+laughed Dick, while Nort inquired:
+</P>
+
+<P>
+"Why don't you tell us more about Zip Foster?"
+</P>
+
+<P>
+"Oh&mdash;you&mdash;say, did you hear anything then?" asked Bud, and his voice
+had in it such a note of anxiety that his companions did not, at the
+time, imagine he might have been putting them off from a much-wanted
+and often-delayed explanation of this mysterious Zip Foster personage.
+</P>
+
+<P>
+"Hear what!" asked Dick.
+</P>
+
+<P>
+"Something like water running," replied Bud. "I have a notion that our
+stream&mdash;I call it ours for it doesn't seem to belong to anyone
+else&mdash;our stream may just trickle off, now and then, into some other
+underground course."
+</P>
+
+<P>
+"Maybe it does," agreed Dick. "But I don't hear any water running."
+</P>
+
+<P>
+"Nor I," added his brother.
+</P>
+
+<P>
+"Maybe I was mistaken," Bud admitted. "But I sure would like to come
+across that missing water of mine!"
+</P>
+
+<P>
+He little realized, nor did the others, what fruit his wish was to
+bear, and that very shortly.
+</P>
+
+<P>
+"I guess what you heard was the echoes," spoke Dick. "I never heard so
+many queer noises."
+</P>
+
+<P>
+"It's like the cave of the winds," murmured Nort. "But it's a great
+adventure all the same, Bud! I mean it would be great if we didn't
+have to worry about the water not coming back," he made haste to add,
+for he realized what it would mean to their new ranch in Flume Valley
+if no drink could be had for the cattle.
+</P>
+
+<P>
+"It beats the finding of the Triceratops all to slathers!" exclaimed
+Dick, "and that was no slouch of a happening, either."
+</P>
+
+<P>
+"Yes, no telling what's ahead of us," spoke Bud, as he walked along,
+unsteadily enough for the way was rough and filled with stones. And,
+as the boys tramped along in the tunnel, part of the time in the very
+bed of the stream that had gone dry, their lanterns cast fantastic
+shadows on the rocky walls. I have said that the stream was dry, but
+this was not strictly true, for in places, where the uneven bed formed
+depressions, there were pools of water. And, in some places, there
+were even little rills trickling along. But they never would reach the
+iron pipe that discharged into the reservoir.
+</P>
+
+<P>
+On and on tramped the boys, pausing, now and then, to hold up their
+lanterns and inspect the rocky walls of the underground tunnel which
+echoed so strangely to their footsteps, and through which swept
+strange, cold and clammy winds.
+</P>
+
+<P>
+"Well, I reckon we'll have to go all the way to the end before we
+discover anything, if we do find it," said Bud, when they had walked on
+for over an hour. Their pace was slow because of the uneven footing.
+</P>
+
+<P>
+"And when we get to the other end and find the water running into the
+pipe at the dam in Pocut River, what then?" asked Nort.
+</P>
+
+<P>
+"We'll hardly find that, I think," said Bud. "Or, I mean, we won't
+have to go all the way to the other end if the water is found running
+there."
+</P>
+
+<P>
+"Why not?" asked Dick.
+</P>
+
+<P>
+"Because, if the water's running in from the dam end of the pipe, we'll
+meet the stream before we get all the way through the tunnel," Bud
+explained. "I meant to call up on the telephone and find out if
+everything was all right at the river end before we started out, but I
+forgot. My theory is that the stream gets into this tunnel from the
+river all right, but is shunted off before it reaches us," he added.
+</P>
+
+<P>
+"How shunted?" Dick wanted to know.
+</P>
+
+<P>
+"That's what I can't tell," spoke Bud. "But why try to puzzle this out
+until we get something better to work on? I'm hungry! What do you say
+that we eat?"
+</P>
+
+<P>
+"Suits me," agreed Nort.
+</P>
+
+<P>
+"I'm not going to vote in the negative," asserted Dick.
+</P>
+
+<P>
+They judged that they were about a quarter way through the mysterious
+tunnel now, and, setting down the lanterns on the rocky floor, the boy
+ranchers took out the food they had brought with them. It would be
+risky to kindle a fire in that enclosed place, Bud decided, as the
+smoke might choke them, though so far they had found an abundance of
+fresh air, a current blowing part of the time in their faces, and part
+of the time in the opposite direction. This proved that there was a
+good draft in the elongated cave, but it was voted best not to take any
+chances, though there was plenty of dried driftwood on the tunnel
+floor, and this could have been used for a blaze.
+</P>
+
+<P>
+But the boys sat about in the gleam of their lanterns, and, while they
+ate the sandwiches they had brought, they talked of the strange
+happenings that had led up to this venture in which they were now
+joined.
+</P>
+
+<P>
+Suddenly Bud, who had just taken up a piece of fruit cake, part of a
+chunk that his pretty sister Nell had sent over from the main ranch
+house a day or so before, stopped chewing in order to listen better;
+for, as you doubtless know, the action of the jaws precludes keen
+attention to outside sounds.
+</P>
+
+<P>
+"What's the matter?" asked Dick, noting his cousin's act.
+</P>
+
+<P>
+"I heard something," Bud answered.
+</P>
+
+<P>
+"I'm hearing things all the while!" declared Dick. "This is the most
+weird place for mysterious noises I ever struck!"
+</P>
+
+<P>
+"But this is different," insisted Bud. "Listen!"
+</P>
+
+<P>
+Nort and Dick stopped chewing and strained their ears to catch the
+sound that had attracted Bud's attention. A strange, rushing,
+whispering echo seemed to fill the tunnel.
+</P>
+
+<P>
+"Doesn't that sound like rushing water?" asked Bud.
+</P>
+
+<P>
+"Yes," agreed Dick, after a moment of intentness; "it does."
+</P>
+
+<P>
+"Look out!" quickly yelled Nort. "It <I>is</I> water, and on the rush, too!
+Jump for your lives! It's a flood!" and making a grab for one of the
+lanterns, that they might not be left in total blackness, he sprang
+toward the rocky side of the tunnel, an example followed by his
+companions.
+</P>
+
+<P>
+And the rush of waters filled the underground cave with a mighty,
+roaring sound.

+<H3 ALIGN="center">
+THE RISING FLOOD
+</H3>
+
+<P>
+Stumbling, slipping, sliding, half-falling, bruising themselves on the
+sharp rocks, but ever leaping forward toward the sides of the tunnel,
+and away from the depressed centre down which they could see the rush
+of waters coming, the boy ranchers at last managed to reach the granite
+wall. Nort had succeeded in grabbing up one of the lanterns, but there
+was no time for Dick or Bud to take one, and the food had to be
+abandoned.
+</P>
+
+<P>
+"Climb up! Climb up, if there's a ledge!" shouted Bud. "We'll be
+drowned if we can't get above the water!"
+</P>
+
+<P>
+He had, somehow or other, brought up in the rear. Though he did not
+admit it, this was because he had shoved his cousins ahead of him,
+hoping thus to enable them to gain a safe place.
+</P>
+
+<P>
+And as Nort and Dick glanced back they saw, in the gleam of the one
+lantern left alight, a white mass of water bearing down on them, and,
+seemingly, filling the tunnel from wall to wall, as it rushed foaming
+and murmuring onward.
+</P>
+
+<P>
+It was as though a dam had suddenly burst, or some obstruction had been
+removed, allowing the pent-up waters to rush along the accustomed
+channel. And if you have ever noticed a dammed-up stream, say in some
+gutter, thus quickly released, you can imagine what happened on a
+larger scale in the tunnel where the boys were.
+</P>
+
+<P>
+The water, normally, flowed only in the four-foot channel. But now it
+spread out on either side, and, of course, was much deeper in the
+centre. But as the tunnel sloped from either wall, in a sort of V
+shape to the centre channel, naturally the parts nearest the side walls
+were less covered by water than the others.
+</P>
+
+<P>
+It was because of this that Bud, Nort and Dick were enabled to maintain
+a footing, though they were knee-deep in water in an instant, and the
+one remaining lantern had to be held up to prevent it from being
+engulfed and extinguished in the sudden flood.
+</P>
+
+<P>
+"Climb up! Climb up!" shouted Bud. "Isn't there some place&mdash;some
+rocky ledge&mdash;where you can find a footing? The water's getting deeper!"
+</P>
+
+<P>
+And this was true. Either the flood was growing at its source (a place
+as yet unknown to the boys) or it was running too rapidly, and in too
+great a volume, to accommodate itself to the tunnel channel, and was
+thus piling up in the vicinity of the boys.
+</P>
+
+<P>
+"What happened? What caused it?" cried Nort.
+</P>
+
+<P>
+"Never mind that&mdash;now!" shouted Bud. "Find the highest place you can,
+and stick!"
+</P>
+
+<P>
+"Suppose the whole tunnel fills?" asked Dick, trying to pierce the
+semi-gloom, and look for a refuge on the rocky wall.
+</P>
+
+<P>
+"If it does we'll have to swim for it," grimly said Bud. "But isn't
+there some place where you can climb up?"
+</P>
+
+<P>
+"This looks like a ledge," Dick answered, as he caught sight of a
+darker shadow on the rocky wall of the tunnel, above his head, when his
+brother swung the lantern.
+</P>
+
+<P>
+"Just what we need!" exclaimed Bud, as he waded through the
+ever-deepening water to the side of his cousins. "Up with you! Here,
+Nort, I'll hold the lantern until you make it!"
+</P>
+
+<P>
+Thus, again, Bud was seeing that his cousins reached a place of
+comparative safety before he looked to himself. For they found the
+ledge, once they had scrambled up to it, well above the water, and wide
+enough to give shelter and a safe perch for all three.
+</P>
+
+<P>
+"Whew! That was touch and go!" murmured Bud, as he leaned back, half
+exhausted, against the rocky wall at the rear of the ledge.
+</P>
+
+<P>
+"I should say so!" gasped Dick. "It all happened so suddenly that I
+don't know yet what it was all about."
+</P>
+
+<P>
+"The stream suddenly started flowing again," spoke Bud. "That's all
+there was to it. Must have been dammed up some place, and suddenly
+released. It's still rising, too," he added, as he leaned forward and
+held the lantern down over the ledge where he and his cousins had taken
+refuge.
+</P>
+
+<P>
+"Rising?" sharply inquired Nort, and there was a tone of anxiety in his
+voice.
+</P>
+
+<P>
+"Yes," remarked Bud, as he swung the lantern to and fro. "We didn't
+get up here any too soon, fellows! Look, the water would be up to our
+waists down there now, in the most shallow place, and it's got speed
+like one of Christy Mathewson's curves!"
+</P>
+
+<P>
+His cousins could see that he had not exaggerated the matter. The
+waters were rising. Inch by inch, and foot by foot, the flood was
+approaching the crest. Where the boy ranchers had sat in the almost
+dry bed of the stream, to eat their lunch, there was now a mad race of
+swirling waters. Where they had stood, before climbing up to the ledge
+of safety, there was now three feet depth of water. And, as Bud had
+said, it was flowing along so swiftly, like the stream which turns a
+mill-wheel, that the boys could hardly have been able to keep their
+feet had they been down in the current, or even on the weakest edge of
+it.
+</P>
+
+<P>
+But, as they were, they were safe for the time being. How long that
+would be the case none could tell. They could see, in the gleam of the
+one lantern saved in the mad rush, that the stream was coursing along
+as it had never coursed before.
+</P>
+
+<P>
+"There must be a powerful lot of water coming out of the reservoir
+pipe," Nort remarked.
+</P>
+
+<P>
+"Biggest ever, with all this water behind forcing it out," agreed Bud.
+"I hope the pipe holds."
+</P>
+
+<P>
+"It isn't as if the pipe were the only outlet," said Dick. "You know
+the water can flow out of the tunnel above, and on either side of the
+conduit."
+</P>
+
+<P>
+"Yes," agreed Bud, "and dad had it put in that way on purpose, so if
+ever a big flood did come, the tunnel could relieve itself without
+ripping away the pipe and reservoir. There's a sort of spillway at one
+side of the reservoir, you know."
+</P>
+
+<P>
+The boys from the east had noticed this. Up to now no water had run
+off through this auxiliary channel, but it was there for emergencies
+such as now had occurred. And the water could find a vent and outlet
+down the middle of Flume Valley, as, indeed, the surplus from the
+reservoir itself did, when there was any.
+</P>
+
+<P>
+"Well, it sure is queer, and we had a mighty narrow escape," remarked
+Nort, as Bud leaned back again with the lantern. "But the fellows back
+at the camp will be scared."
+</P>
+
+<P>
+"I reckon they will," admitted Bud. "They'll see the water spouting
+out, in a greater volume than ever before, and they'll imagine all
+sorts of things have happened to us."
+</P>
+
+<P>
+"Well, nothing has happened yet&mdash;except we've lost two perfectly good
+lanterns, and what grub we didn't eat," asserted Nort.
+</P>
+
+<P>
+"But something else may happen," said Bud in a low voice, as, once
+more, he leaned forward, and again held the lantern over the edge of
+the rocky ledge.
+</P>
+
+<P>
+"What?" Dick wanted to know.
+</P>
+
+<P>
+"Look," was what Bud replied. And his cousins, glancing down, saw that
+the waters were rising, rising, rising!
+</P>
+
+<P>
+When would they stop?
+</P>
+
+<BR><BR><BR>
+

+
+<H3 ALIGN="center">
+CHAPTER XIII
+</H3>
+
+<H3 ALIGN="center">
+WHERE DID IT GO?
+</H3>
+
+<P>
+Pressing back toward the rocky ledge, against which they leaned, gazing
+with fearsome eyes at the rising waters, on which the lantern-light
+shone fitfully, and almost holding their breaths at times, so great was
+the strain, the boy ranchers waited&mdash;for what they scarcely knew. And
+yet they did, in a measure.
+</P>
+
+<P>
+For they waited to see if the waters would stop rising, a happening, as
+they well knew, which, alone, could save their lives.
+</P>
+
+<P>
+As one of them had remarked, they might have to swim for it. But,
+looking at the foaming current, dashing along over jagged rocks on
+which the boys had more than once stumbled, they knew what a risk that
+effort to escape would bring.
+</P>
+
+<P>
+And should the water fill the whole tunnel they would have no earthly
+chance!
+</P>
+
+<P>
+For only a fish can exist in a hose or pipe completely filled with
+water, and that is what the tunnel would become if the water rose to
+the roof&mdash;merely a great, underground rocky pipe for the conveying of
+the liquid from Pocut River.
+</P>
+
+<P>
+So you can easily imagine with what anxiety Bud, Nort and Dick watched
+the rising water. Every now and again one of them would lean over the
+ledge, swinging the lantern to and fro, so its gleams would be
+reflected in the hurrying, foaming stream, and indicate how fast it was
+rising.
+</P>
+
+<P>
+At first the rate of rise had been rapid. But as the boys, again and
+again, made observations in the semi-gloom Bud, at length, uttered a
+joyful cry.
+</P>
+
+<P>
+"Look!" he shouted, pointing with trembling finger at the foamy flood
+close, now, to the top of the ledge. "Look!"
+</P>
+
+<P>
+"What&mdash;a big fish?" asked Dick.
+</P>
+
+<P>
+"Fish nothing!" retorted his cousin. "But the water is going down!
+Look, it isn't as high as it was. I can see a wet mark where it came
+up to, and it's two inches below that now! The flood is going down!"
+</P>
+
+<P>
+"Are you sure?" asked Nort, eagerly.
+</P>
+
+<P>
+"Look for yourselves!" invited Bud, handing over the lantern.
+</P>
+
+<P>
+Nort's observation was confirmatory of his cousin's.
+</P>
+
+<P>
+"She <I>is</I> going down!" remarked Nort. "And just in time, too!"
+</P>
+
+<P>
+How truly he spoke was evidenced by that fact that another inch of rise
+would have sent the flood over the ledge on which the boys rested!
+</P>
+
+<P>
+So narrow had been their escape!
+</P>
+
+<P>
+"If she only doesn't begin to rise again, after she starts going
+down&mdash;as you say she is&mdash;we'll be all right," said Dick. "But if she
+comes up&mdash;&mdash;"
+</P>
+
+<P>
+He did not finish what he started to say, but his companions knew what
+he meant, and they looked each other in the face with grave
+apprehensions.
+</P>
+
+<P>
+"The question is now," went on Bud, as he again took an observation and
+noted that the flood was still on the descent, "how long we shall have
+to stay here."
+</P>
+
+<P>
+"If it's too long we'll be wanting some of that grub which was washed
+away," asserted Diet. "In fact I dropped a sandwich half eaten."
+</P>
+
+<P>
+"Same here," remarked his brother. "But let's hope that it will go
+down as suddenly as it came up."
+</P>
+
+<P>
+That was all they could do&mdash;hope; but it bore fruits, for in about an
+hour, as they ascertained by glances at their watches, the flood was
+almost down to the normal channel of the underground stream.
+</P>
+
+<P>
+"And if it will only stay there we can venture to keep on to the other
+end of the tunnel," spoke Bud.
+</P>
+
+<P>
+"Will you do that?" Dick wanted to know.
+</P>
+
+<P>
+"Why not?" asked Bud. "We want to see what happened, and where this
+water goes to when it disappears so suddenly; don't we?"
+</P>
+
+<P>
+"Yes," agreed Dick. "But I thought, after our escape, that we had
+better head back for camp."
+</P>
+
+<P>
+"It's about six of one and half a dozen of the other," asserted Bud.
+"We're almost half way through the tunnel, now, and we might as well
+keep on. I'd like to solve this mystery, and we can't if we call it
+off now."
+</P>
+
+<P>
+"That's right," assented Nort. "We don't run any more danger going on
+to the river end of the tunnel than we would in going back to the camp
+end. That is unless we discover a big cavern, or hole through to
+China, in the other end of the tunnel. Even then we might be able to
+skirt around it."
+</P>
+
+<P>
+"Let's go on!" suggested Bud, as he prepared to climb down off the
+ledge. "This thing has my goat!"
+</P>
+
+<P>
+"Speaking of goats is most appropriate on a cattle ranch," laughed
+Nort, and the spirits of all the lads were lighter now. "But let's
+keep on to the end for which we started!"
+</P>
+
+<P>
+This was agreed to and, after waiting a little while to make sure that
+the waters were not again going to rise, away started the boy ranchers.
+They were traveling lighter now, for they only had one lantern, and no
+food to carry.
+</P>
+
+<P>
+The remainder of the tunnel was as the first part had been&mdash;a great,
+uneven tube through the mountain, twisting and turning here and there,
+sometimes the roof being so high that it did not show in the swinging
+lantern-light, and again being low enough, almost, for the boys to
+touch.
+</P>
+
+<P>
+On all sides was evidence that the flood had been here, as it had been
+at the place where the boys took refuge. Now and then they came to
+deep pools, which they had to skirt, and, in one case, leap over.
+</P>
+
+<P>
+Suddenly, as they were walking along, the lantern which Bud was
+carrying went out, leaving them in pitch blackness!
+</P>
+
+<P>
+"Hello! What's the idea?" asked Nort.
+</P>
+
+<P>
+"Did you do it on purpose?" asked Dick.
+</P>
+
+<P>
+"Why, no, of course not!" asserted Bud. "The oil must be gone, though
+I filled it before we started, and it ought to have burned longer than
+this."
+</P>
+
+<P>
+"Whew! This is tough!" bemoaned Nort. "Left in the dark!"
+</P>
+
+<P>
+"Not altogether!" exclaimed Bud. "I brought some candles!"
+</P>
+
+<P>
+"Great!" voiced Nort. "Light up!"
+</P>
+
+<P>
+Which Bud did, placing a short length of candle inside the lantern, by
+fastening it, with some grease that hardened, on top of the oil
+reservoir of the wick.
+</P>
+
+<P>
+"But I can't understand what happened to the lantern," went on Bud,
+making an examination by means of a second candle, from the store he
+had, luckily, placed in his pocket. "Oh, yes, I can!" he went on.
+</P>
+
+<P>
+"What?" asked Dick.
+</P>
+
+<P>
+"One of the soldered seams of the lantern oil tank started, and the oil
+has leaked out. Guess one of us must have banged it against a stone
+when we made the rush. But we'll be all right. A candle in the
+lantern is nearly as good as the regular wick."
+</P>
+
+<P>
+It was not quite so good, but the boys made the best of it as they
+tramped on through the tunnel, hoping to reach the river end without
+another flood, or any mishap.
+</P>
+
+<P>
+"The water seems to be behaving very nicely," observed Nort, as they
+all saw that the stream was well within its rocky channel.
+</P>
+
+<P>
+"But what gets me," said Bud, "is where it goes to&mdash;when it goes. I
+mean where does it disappear to? We haven't come to a single branch
+tunnel, or any other passage that could drain off the river water."
+</P>
+
+<P>
+"That's right," agreed his cousins.
+</P>
+
+<P>
+"But maybe we'll find it further on," suggested Nort.
+</P>
+
+<P>
+"We'll soon know, for we must be close to the other end now," observed
+Bud. "Our candles are holding out well."
+</P>
+
+<P>
+They had come several miles, as they knew by the time consumed. The
+way through the tunnel had been uphill all the way, as it must needs be
+to allow the water to run down to the reservoir in Flume Valley. But,
+so far, they had seen nothing to indicate any side channel for the
+stream&mdash;any place that might drain off the water, and return it in such
+a sudden volume as to cause a flood.
+</P>
+
+<P>
+"I can't understand it," Bud remarked as he swung the lantern to and
+fro. "It sure is a puzzle. Where does the water disappear?"
+</P>
+
+<P>
+His cousins could offer no solution. All the way along they had
+carefully scanned the underground stream, but there appeared no break
+in its uneven, rocky bank in the middle of the tunnel.
+</P>
+
+<P>
+"Well, let's keep on," suggested Nort. "We aren't at the end yet, and
+it may be close to the intake&mdash;I mean the mysterious influence&mdash;that
+shuts off our water supply and turns it on again, may be there.
+Forward, march!" he cried gaily.
+</P>
+
+<P>
+Together they started off, having come to a momentary halt to inspect a
+place wider and deeper than usual, when Bud suddenly came to a stop and
+exclaimed:
+</P>
+
+<P>
+"Some one is coming!"
+</P>

+CHAPTER XIV

+
+<H3 ALIGN="center">
+A NIGHT ATTACK
+</H3>
+
+<P>
+Instantly the boy ranchers came to a halt, standing there in the
+tunnel, beside the running water. They had nearly reached the other
+end of the flume, and could dimly see, ahead of them, a faint glow,
+which told of daylight to come. Bud, who was carrying the lantern,
+made shift to hide it behind the bodies of himself and his cousins, so
+that the unknown, approaching, might not have them at a disadvantage,
+he being in the dark.
+</P>
+
+<P>
+"Who you reckon it is?" asked Nort. He and his brother were rapidly
+falling into the custom of using the picturesque if not always elegant
+talk of the west. Nort spoke in a whisper, and Bud answered in the
+same tone.
+</P>
+
+<P>
+"Can't imagine who it may be," spoke the western lad, "but if it's
+Hank, Del Pinzo, or any of their gang&mdash;&mdash;"
+</P>
+
+<P>
+He did not finish, but a slight movement told that he was freeing his
+.45 in its holster, an example quickly followed by Nort and Dick.
+</P>
+
+<P>
+Meanwhile the steps continued to approach, echoing loudly in the
+vaulted tunnel, as if the maker of them had no design to conceal his
+movements. In another few seconds the boys saw, looming in front of
+them, as displayed by the gleam of their half-hidden lantern, a bulky
+figure. At the same moment the figure seemed to become aware of the
+presence in the tunnel of others besides himself.
+</P>
+
+<P>
+"Who's there?" came in sharp challenge.
+</P>
+
+<P>
+And what a relief it was to the boy ranchers when they heard that voice.
+</P>
+
+<P>
+"Slim!" cried Bud. "Slim Degnan!"
+</P>
+
+<P>
+"That you, Bud?" called the foreman of Diamond X ranch, as he
+recognized the voice of his employer's son, while Bud, in turn, sensed
+whom the looming figure was.
+</P>
+
+<P>
+"Sure!" Bud joyously answered. "And Nort and Dick are here! Say,
+what's the matter with our water? Is there a stoppage at the dam?"
+</P>
+
+<P>
+"Nary a stop, but your dad got a telephone from your side-partners at
+the valley camp, saying you'd started through the tunnel to see what
+caused the shut-off. I happened to be over near Square M, seeing if I
+could get on the track of that cattle epidemic, and they relayed your
+dad's message on to me. So I hit the trail for here."
+</P>
+
+<P>
+"What was dad's message?" Bud wanted to know.
+</P>
+
+<P>
+"Why, he said you, and them tenderfeet&mdash;&mdash; No, I'll take <I>that</I> back!"
+Slim hastened to say as he recalled all that Nort and Dick had done.
+"Anyhow, he said they shouldn't have allowed you to come in the tunnel
+alone, and he asked some of the men, from this end, to go in and see if
+they could locate you."
+</P>
+
+<P>
+"You found us," said Bud.
+</P>
+
+<P>
+"Well," resumed Slim, "I just got here, heard the news and I started
+in. Some of the others are coming, but I guess we don't need to make
+any search. You're here!"
+</P>
+
+<P>
+"And more by good luck than good management," asserted Dick.
+</P>
+
+<P>
+"How's that?" asked Slim, as they all started for the opening at the
+river end of the tunnel, where daylight dimly showed.
+</P>
+
+<P>
+"Why, when we started in at the other side the stream was dry,"
+explained Bud. "There wasn't a drop coming through the pipe into the
+reservoir, and we left, early this morning, to see what the trouble
+was. When we got half way through the stream suddenly began flowing,
+and there was a regular flood. Only that we found a ledge to climb up
+on, we'd been drowned!"
+</P>
+
+<P>
+"As bad as that!" gasped Slim.
+</P>
+
+<P>
+"Every bit!" Dick asserted.
+</P>
+
+<P>
+"But tell me," went on Bud, "did the water stop at the river end, Slim?
+Was there any stoppage at the dam or pipe?"
+</P>
+
+<P>
+"Nary a stop, Bud," Slim answered. "They told me, when I started in,
+that the water had been flowing all night, as usual, and they didn't
+see why you claimed there was none at your end."
+</P>
+
+<P>
+"By Zip Foster! But there's something mighty strange here!" cried the
+boy rancher.
+</P>
+
+<P>
+"You intimated good and plenty that time!" declared Slim as he and the
+boys reached the river end of the tunnel, where the intake pipe took
+the water from the Pocut stream, delivering it to the tunnel.
+</P>
+
+<P>
+"But here's a queer part of it," went on Dick, as they joined the other
+cowboys who were preparing to follow Slim in, and search for the
+Diamond X lads. "No such body of water, as so nearly overwhelmed us,
+ever came through this pipe," and he pointed to the one that tapped the
+dammed-up water of the river.
+</P>
+
+<P>
+"That's right!" agreed Bud. "This thing gets worse and worse! We'll
+never get to the bottom of this mystery!"
+</P>
+
+<P>
+"You're right!" declared one of the cowboys. "When you're dealing with
+them underground water-courses you never know what you're up against.
+The old Indians and Spaniards who lived here hundreds of years ago had
+their own troubles, and maybe they wished them same troubles on to you."
+</P>
+
+<P>
+"What you mean?" asked Slim. "That's all bosh!"
+</P>
+
+<P>
+"Bosh nothin'!" declared another. "You read history an' you'll get
+lots of cases where streams showed up, and then vanished under
+mountains, more than once."
+</P>
+
+<P>
+"A heap sight you know about <I>hist'ry</I>!" laughed Slim in good-natured
+raillery.
+</P>
+
+<P>
+"Well, this is sure queer, anyhow!" declared Bud. "Is there any
+history of the stream that waters our valley?" he asked the cowboy who
+had made the assertion.
+</P>
+
+<P>
+"Not your particular one," was the answer, "but there's lots of just
+such cases mentioned&mdash;hidden water-courses and all that."
+</P>
+
+<P>
+"Well, there's something wrong," agreed Bud, "and I believe there must
+be some place along the tunnel where our water shunts itself off at
+times, and turns itself on again. We were looking for just such a
+place."
+</P>
+
+<P>
+"And you didn't find it?" asked Slim.
+</P>
+
+<P>
+"Nary a find!" asserted Bud.
+</P>
+
+<P>
+"But we aren't going to give up, just on that account!" said Nort.
+</P>
+
+<P>
+"Bet you not!" added his brother. "We'll try it again, and take a
+canoe with us, so if the dry water-course suddenly turns wet, we can
+paddle along it."
+</P>
+
+<P>
+"Well, it seems to be all right now," spoke Slim. "And you'd better
+'phone your father that you're all right, Bud. He'll be anxious to
+hear."
+</P>
+
+<P>
+And after Mr. Merkel had been assured, over the wire, of the safe
+transit of his son and nephews through the tunnel, the boys' camp was
+called up, to let Old Billee and the others know that no accident had
+happened.
+</P>
+
+<P>
+"Gosh! I'm glad to hear that!" said the veteran cowboy over the wire.
+"When we see that there water come gushin' out, we thought sure you was
+goners, Bud!"
+</P>
+
+<P>
+"Then the water is running again?" Bud asked.
+</P>
+
+<P>
+"Absolutely!" declared Billee. "You comin' back here?"
+</P>
+
+<P>
+"Sure! But <I>over</I> the mountain&mdash;not <I>under</I> it."
+</P>
+
+<P>
+Bud and his boy rancher chums remained that night at the store
+settlement near the dam, getting beds in what passed for a hotel. It
+was too late to secure horses and ride over Snake Mountain trail back
+to Flume Valley.
+</P>
+
+<P>
+While thus having a night of leisure, and seeing such sights as were to
+be viewed in the little town, Bud and his chums discussed the queer
+situation of the mysteriously disappearing and reappearing water. But,
+talk as they did, and venture opinions as they and their cowboy friends
+did, no one could hit on a solution.
+</P>
+
+<P>
+"We'll just have to make another and more careful inspection," declared
+Nort.
+</P>
+
+<P>
+"That's what!" agreed Bud.
+</P>
+
+<P>
+They learned from Slim that the situation regarding the cattle epidemic
+at Square M ranch was not much better. All stock which had not been
+exposed to the infection had been removed, either to Diamond X,
+Triangle B or Flume Valley, and the infected steers remaining there
+were being treated by a veterinarian whom Mr. Merkel had engaged.
+</P>
+
+<P>
+"But they're slowly dying off," Slim reported. "And I don't believe
+Square M ranch will ever be safe to use again."
+</P>
+
+<P>
+"Why not?" asked Bud.
+</P>
+
+<P>
+"Because there must be some infection in the grass there to have made
+so many of the cattle sicken and die."
+</P>
+
+<P>
+"Maybe it was something else," suggested Nort.
+</P>
+
+<P>
+"Well, maybe," assented the foreman. "It's about as mysterious as that
+underground river of yours. Had any more warnings, Bud?"
+</P>
+
+<P>
+"No, I guess they're done with. And I believe it's a natural cause,
+and not due to any work of enemies, that accounts for the queer way our
+flume acts."
+</P>
+
+<P>
+"Um!" spoke Slim musingly, and that was all he would say.
+</P>
+
+<P>
+Borrowing horses from their friends, the boy ranchers next day made the
+trip over Snake Mountain and returned to camp, finding matters there in
+good shape. There was an abundance of water in the reservoir, and the
+pipe was flowing freely.
+</P>
+
+<P>
+For more than a week nothing happened. The cattle at Flume Valley,
+including those of the boy ranchers, and the herd transferred from
+Square M to save it from the epidemic, were doing well, abundant grass
+and water being their portions.
+</P>
+
+<P>
+There was no lack of hard work for the boys and their cowboy
+assistants, for it was not all easy sailing. Occasionally bunches of
+steers would stray, and have to be driven back by hard riding. There
+were night watches to be carried on, and another bunch of cattle was
+shipped away.
+</P>
+
+<P>
+Bud, Dick and Nort hazed them over to the railroad, and on the trip a
+small-sized stampede gave them all they wanted to handle. But they
+were true sons of the west, and did not complain.
+</P>
+
+<P>
+"Whew! That was hot, while it lasted!" exclaimed Bud, as he and
+cousins managed to get the stampeding animals quieted, after they had
+tried so hard to run off by themselves, in varying directions.
+</P>
+
+<P>
+"Yes, a thing like that gives you an appetite," remarked Dick.
+</P>
+
+<P>
+"As if <I>you</I> ever needed any stimulant!" laughed Nort. "I never saw
+the time yet when you had to be offered an inducement to sit up to
+grub!"
+</P>
+
+<P>
+"You either!" retorted the stout lad. "But, speaking of grub, when do
+we eat, Bud?"
+</P>
+
+<P>
+"Might as well make it right soon," was the answer. "Now that we have
+the steers quieted they'll be glad enough to take it easy. I planned
+to water 'em at the next stopping place, and that will give us a chance
+to see what Buck Tooth put up for us."
+</P>
+
+<P>
+"Stay there all night; will we?" asked Nort.
+</P>
+
+<P>
+"Might as well," assented his cousin. "No use running all the fat off
+our stock. We want 'em to weigh as heavy as possible."
+</P>
+
+<P>
+This was good business tact on the part of the boy ranchers. For
+cattle are generally sold by weight, either "on the hoof," which means
+alive and as they stand in the stock yards, or by weight after being
+slaughtered. In the case of ranchers "on the hoof" is generally
+understood.
+</P>
+
+<P>
+And driving a bunch of steers at too great a speed from the ranch to
+the railroad would make them thin, "running off their fat," so to
+speak, thus losing all the advantages of the rich fodder to which they
+had had access. And when it is considered that it is not at all
+difficult to cause a steer to lose from ten to fifteen pounds by means
+of poor driving, and when to this statement is added the fact that this
+loss is multiplied in hundreds of steers, Bud's state of mind can
+easily be imagined.
+</P>
+
+<P>
+"Yes, we'll get 'em quieted down, and take it easy ourselves,"
+suggested the Western lad. And, a little later when some of the steers
+broke into a run, Nort exclaimed:
+</P>
+
+<P>
+"Are they stampeding again?"
+</P>
+
+<P>
+"No. I reckon they just smell water," Bud answered.
+</P>
+
+<P>
+This proved to be true, and this contagion spread all through the herd,
+though with no ill effects, for the water hole was not far off and,
+reaching it, the animals stopped to drink.
+</P>
+
+<P>
+There was some confusion and excitement because so many thirsty cattle
+all wanted to drink at once, but it did not last long, and Bud, Nort
+and Dick were glad when they could slip from their saddles, tossing the
+reins over their ponies' heads as an intimation to the animals not to
+stray.
+</P>
+
+<P>
+"Oh boy! But I'm tired!" exclaimed Nort, sighing.
+</P>
+
+<P>
+"Add hungry to that and I'm with you," said his brother. For there had
+been days of long and difficult work in preparing this bunch of cattle
+for shipment.
+</P>
+
+<P>
+"Getting tired of the game?" asked Bud, as he rustled up some sticks of
+greasewood to make a fire over which they might boil coffee and fry
+bacon.
+</P>
+
+<P>
+"Not on your life!" laughed Nort. "We're in the game to stick!"
+</P>
+
+<P>
+"Sure thing!" asserted Dick.
+</P>
+
+<P>
+They made a simple but ample meal over the camp fire and then, as
+evening settled down over the vast prairies, and quiet enfolded them
+like some soft mantle, they lay on their blankets and gazed at the
+feeding cattle.
+</P>
+
+<P>
+The steers were very quiet now, evidently feeling quite satisfied with
+the manner in which they had been treated, and having, of course, no
+intimation of the fate in store for them. They had food and water and
+that is all they required. Overhead was the cloudless sky, in which
+sparkling stars were beginning to stud themselves.
+</P>
+
+<P>
+"I hope the market is well up in price when we get to the yards,"
+observed Bud, idly chewing on a spear of grass.
+</P>
+
+<P>
+"Yes, it would be dandy to get a big price for this stock," agreed Nort.
+</P>
+
+<P>
+The boy ranchers were rapidly becoming interested in the business end
+of their venture, as they had been, for some time, in the more
+picturesque side. The difference of a fraction of a cent in the price
+of cattle on the hoof meant the difference of several hundred of
+dollars where there were many tons of meat to be considered.
+</P>
+
+<P>
+"Well, we'd better ride herd a little while, to make sure they get
+bedded down quietly," suggested Bud, as it began to get darker. "Then
+we'll roll up and snooze ourselves."
+</P>
+
+<P>
+This "bedding down" of the cattle, meaning thereby inducing them to get
+quiet enough so they would lie down contentedly chewing their cuds, was
+part of the routine of a cowboy's life.
+</P>
+
+<P>
+"Some of 'em have already started in," observed Nort, as he went up to
+his pony, which, with the other two animals, had been contentedly
+grazing. "Looks like they'd lived here all their lives."
+</P>
+
+<P>
+He indicated a score or more of the steer's that were stretched out on
+the rich grass which at once formed their food and their bed.
+</P>
+
+<P>
+"Yes, I reckon we'll have a quiet night," observed Bud.
+</P>
+
+<P>
+The three chums slowly rode around the bunch of cattle, the lads
+occasionally breaking into the chorus of some song.
+</P>
+
+<P>
+The cattle seemed to like this singing&mdash;not that this is to be
+considered a compliment to the voices of Nort, Dick and Bud, though
+their tones were far from unmusical. But the fact is that animals of
+most sorts are fond of music in any form, and nothing so seems to
+soothe and quiet a bunch of cattle, especially at night, as the singing
+of the herders.
+</P>
+
+<P>
+Perhaps it is due to this fact that we have so many cowboy songs with
+an interminable number of verses, in which there is little sense or
+sequence&mdash;a mere jumble of words, often repeated. The cattle seem to
+care more for the tune than for the sentiment.
+</P>
+
+<P>
+At any rate the bunch from Flume Valley grew more quiet as the night
+became darker, and when the remains of their camp fire gleamed dully in
+the blackness, as they made their way back to it, Bud and his cousins
+considered their work done for the day.
+</P>
+
+<P>
+"We won't stand any regular watch," Bud said. "I think they'll be all
+right. But if we should hear a disturbance&mdash;I mean any one of us&mdash;he
+can awaken the others, and we'll do whatever we have to."
+</P>
+
+<P>
+"And if we have any luck we won't have to roll out," observed Nort, as
+he spread out his blankets and tarpaulin, which last was to keep the
+dampness of the ground away.
+</P>
+
+<P>
+"Then I'm going to cross my fingers for luck," observed Dick.
+</P>
+
+<P>
+Save for the occasional distant howl of a coyote, or the uneasy
+movement of an occasional steer, with, now and then, the clashing of
+the horns of some of the beasts, there was silence in the camp. Bud
+was the first to fall asleep, because he was more accustomed to this
+sort of life than were his cousins. But they were rapidly falling in
+with the ways of the west, which teaches a wayfarer to consider home
+wherever he hangs up his hat, and his bed any place he can throw his
+blanket and saddle.
+</P>
+
+<P>
+But finally Nort and Dick dropped off into slumber, which became
+sounder as the hours of night passed. All three of the boy ranchers
+were tired and they were in the most healthful state imaginable,
+brought about by their life in the open.
+</P>
+
+<P>
+"What hour it was Dick had no idea, but he was suddenly awakened by
+sensing some movement near him&mdash;too near for comfort considering his
+exposed sleeping position. For he felt something cold and clammy at
+the back of his neck, as though a chunk of ice, or a hand dipped in
+cold water, had touched him.
+</P>
+
+<P>
+"Hi! Who's doing that?" yelled Dick, for he had a sudden dream that he
+was back at school, and some one was playing a trick on him. "Cut it
+out!"
+</P>
+
+<P>
+No sooner had he spoken than he realized that he had awakened Nort and
+Bud, for by the flickering light of the embers of the fire he could see
+them sitting up and staring over at him.
+</P>
+
+<P>
+"What's the matter?" demanded Bud.
+</P>
+
+<P>
+"Something tickled the back of my neck," declared Dick. "I guess a
+coyote must have been picking up scraps of food, and smelled of me.
+Hope he didn't take me for a dead one!"
+</P>
+
+<P>
+"Coyote!" exclaimed Bud. "I don't believe you could get one to come
+near you, not as long as you breathed. It must have been a&mdash;&mdash;"
+</P>
+
+<P>
+"Snake!" broke in Nort, without thinking of what the word might mean.
+</P>
+
+<P>
+"Wow! Don't say that!" cried Dick, and he leaped up, scattering his
+blanket and tarpaulin each in a different direction.
+</P>
+
+<P>
+"Shut up!" commanded Bud, laughing. "Do you want to start the cattle
+off again? If it was a snake it won't hurt you, and it was probably
+more scared than you, Dick."
+</P>
+
+<P>
+"Yes&mdash;maybe!" said the other. He lighted a stick of greasewood at the
+fire, and looked about his part of the sleeping ground. But he found
+nothing in the animal line.
+</P>
+
+<P>
+"Guess you dreamed it!" said Nort.
+</P>
+
+<P>
+"I certainly did not!" emphatically declared his brother.
+</P>
+
+<P>
+"Well, go to sleep again," advised Bud. "If you feel it a second time
+call me!"
+</P>
+
+<P>
+"Huh! I'll do that all right!" declared Dick. He carefully shifted
+his sleeping place, making a searching examination of the ground before
+spreading out his tarpaulin. And he was some little time in dropping
+off to slumber again.
+</P>
+
+<P>
+But there was no further disturbance in the night, and in the morning
+Bud looked for marks on the ground, declaring the visitor had been a
+prairie dog, which Dick declared his unbelief in, sticking to the snake
+theory as being more sensational.
+</P>
+
+<P>
+After breakfast they started to drive the cattle again, reaching the
+railroad yards and successfully transacting the business of selling
+their stock.
+</P>
+
+<P>
+It was the night that Bud and his cousins returned from having driven
+the steers to the railroad yard that something happened which again
+brought to the front all their worries and anxieties.
+</P>
+
+<P>
+They were all seated about the camp fire, and Pocut Pete had just
+arisen, remarking that he would get ready for his turn at night-riding,
+when there was a sort of hissing in the air over the heads of those
+gathered about the blaze, and something hit the ground in the midst of
+the circle.
+</P>
+
+<P>
+"What's that?" exclaimed Nort
+</P>
+
+<P>
+"An arrow!" answered Bud, and so it proved. An Indian arrow&mdash;of the
+sort used by the Redmen years ago, and hard to pick up now, even as
+relics&mdash;quivered in the ground near the blaze. And by the flickering
+flames it was seen that a paper was rolled about it.
+</P>
+
+<P>
+In an instant Bud had leaped to his feet, plucked the arrow from the
+ground, and torn off the paper. By the light of the fire he read it.
+</P>
+
+<P>
+"Another warning!" cried Bud.
+</P>
+
+<P>
+"What does it say?" demanded Dick.
+</P>
+
+<P>
+Bud read:
+</P>
+
+<BR>
+
+<P>
+"Two wasn't enough. This is the third and last! Leave Flume Valley!"
+</P>
+
+<BR>
+
+<P>
+There was silence for a moment, and then Bud, crushing the scrawled
+warning in his hand, cried:
+</P>
+
+<P>
+"I'd like to see 'em drive me out!"
+</P>
+
+<P>
+"That's th' way to talk!" shouted Yellin' Kid. "We'll stick!"
+</P>
+
+<P>
+They gathered about, discussing the sinister warning that had been sent
+to them in such a sensational manner. There was no clue to tell where
+it had come from, for no one had noticed the direction whence the arrow
+had been shot. The message itself was written, or, rather, printed on
+a piece torn from a paper bag, and the writing was in pencil. The
+paper was common enough in those parts, and the use of printing, in
+place of handwriting, would, it seemed, preclude any tracing.
+</P>
+
+<P>
+"We'd better keep a double watch to-night," suggested Bud, when a hasty
+inspection in the vicinity of the camp had revealed no one.
+</P>
+
+<P>
+"We shore will!" asserted Old Billee.
+</P>
+
+<P>
+The night hours passed, a double guard watching with keen eyes for any
+sign of strangers approaching the reservoir or the cattle. But, in
+spite of all precautions, the half-expected happened.
+</P>
+
+<P>
+It was toward morning, when Nort and Dick had turned out of warm beds
+to relieve Pocut Pete and Snake Purdee that a confused noise at the
+extreme end of the valley gave notice that something was wrong.
+</P>
+
+<P>
+"What's that?" asked Bud, who had ridden into camp at the conclusion of
+his tour of duty.
+</P>
+
+<P>
+As if in answer came distant shots, the howls of coyotes and the
+snorting of cattle, mingled with a rush which told its own story.
+</P>
+
+<P>
+"Stampede!" yelled Bud. "They're trying to stampede our herd and drive
+'em off! Come on, fellows!"
+</P>
+
+<P>
+And all within the sound of his voice rallied to repel the night
+attack, for such it proved to be.
+</P>
+
+<P>
+Leaping into their saddles, Nort and Dick followed Bud toward the scene
+of the disturbance. They saw the cattle running to and fro, and in the
+slivers of light that leaped from the muzzles of guns which were shot
+off at intervals, they descried figures swiftly riding backward and
+forward, evidently trying to cut out bunches of cattle.
+</P>
+
+<P>
+Action had followed rapidly on the heels of the sinister arrow warning.

+THE BRANDING IRON
+</H3>
+
+<P>
+"Come on, boys! Come on!" shouted Bud, as he spurred off in the
+darkness, followed by Nort and Dick. "They're trying to drive 'em off
+through the lower end of the valley! We've got to stop 'em!"
+</P>
+
+<P>
+"You said it!" shouted Dick.
+</P>
+
+<P>
+"Who are they?" yelled Nort
+</P>
+
+<P>
+Bud had no time to answer. What was needed, then, was quick action to
+prevent his own and his cousins', as well as his father's stock from
+the Square M ranch, being driven off by unscrupulous rustlers.
+</P>
+
+<P>
+For that this night attack was made by these marauders of the plains
+was not to be doubted.
+</P>
+
+<P>
+"Ride hard, boys! Ride hard!" shouted Old Billee as he galloped up
+beside the boy ranchers.
+</P>
+
+<P>
+And they were riding hard&mdash;all of them, including the cow punchers who
+had come in from their night's duties, expecting to be relieved. It
+was at this favorable&mdash;for them&mdash;moment that the rascals had made their
+attack.
+</P>
+
+<P>
+It was so dark that only, indistinctly, could the forms of raiders be
+made out. But there were several of them, leaning low over the necks
+of their galloping steeds, and endeavoring to create a panic among the
+cattle so that a stampede would result. Once this started it would be
+a comparatively easy matter for them to "cut out" as many choice
+specimens as possible, driving them to some secret place. There the
+brands could be "blurred," or changed, and Diamond X Second would be
+out several thousands of dollars.
+</P>
+
+<P>
+"There they are!" yelled Bud, as, riding between Nort and Dick, he saw
+a group of men swinging their big hats and heard them shouting to
+frighten the already thoroughly roused cattle.
+</P>
+
+<P>
+But though Bud thus indicated the presence of the rustlers it was not a
+very clear sight of them that he or his companions had. Only for the
+fact that those of Flume Valley rode together, and saw the indistinct
+forms ahead of them, could it be made certain that the unknown ones
+were the enemy.
+</P>
+
+<P>
+"Crack!"
+</P>
+
+<P>
+Bud's gun shot out a menacing warning, for he had fired high in the
+air, above the heads of the rustlers. He had borne in mind his
+father's injunction never to shoot at a human being unless vital
+necessity required it.
+</P>
+
+<P>
+"And I'd rather lose all my cattle than kill anyone," Bud said
+afterward. "Unless I had to do it to save my life."
+</P>
+
+<P>
+It was for this reason that he had fired high, and his example was
+followed by his cousins.
+</P>
+
+<P>
+But that this consideration on the part of our friends was not
+appreciated, was made plain, a moment later, when Old Billee exclaimed:
+</P>
+
+<P>
+"That was a close one!"
+</P>
+
+<P>
+His words followed the whining song of a bullet as it zipped through
+the air, too close to the heads of himself and the boy ranchers to be
+comfortable.
+</P>
+
+<P>
+"I'm goin' t' give 'em some of th' same medicine!" shouted Yellin' Kid,
+and his gun spat fire, but straight out, and not at a high angle.
+</P>
+
+<P>
+Following it, almost instantly, was a yell of pain from one of the
+rustlers&mdash;which one could not be told because of the mix-up and the
+darkness, but it was a yell nevertheless.
+</P>
+
+<P>
+"You winged one!" cried Snake Purdee.
+</P>
+
+<P>
+"I meant to!" was the Kid's grim answer.
+</P>
+
+<P>
+"Fire high, boys!" cried Bud. "If we can scare 'em off, so much the
+better!"
+</P>
+
+<P>
+"Don't reckon they're th' kind that scares easy," objected Old Billee.
+"But we've got 'em on the run!" he exclaimed, a moment or two later,
+when Bud and his party had ridden around some intervening bunches of
+cattle, and were headed straight for the night attackers.
+</P>
+
+<P>
+This seemed to describe the situation. So promptly had the boys of
+Flume Valley ridden out to repell the raid that the rustlers had no
+time to stampede the cattle, and cut out some to drive away. Now it
+seemed there must be a clash&mdash;a coming together of the two forces.
+</P>
+
+<P>
+But the rustlers, unscrupulous as they were, evidently knew when
+discretion was the better part of valor. They fired several more
+shots, one of which scratched Old Billee while another gave an ugly
+wound to Snake Purdee.
+</P>
+
+<P>
+Then, with yells of defiance, and before our boys could come close
+enough to recognize any of the raiders, the rustlers galloped off, not
+having succeeded in driving away any cattle.
+</P>
+
+<P>
+But their attack had not been without damage to Flume Valley stock.
+For two valuable steers had been shot, and so wounded that they had to
+be killed, while several calves were trampled on and crushed into
+shapeless masses.
+</P>
+
+<P>
+This, together with two wounded men, Old Billee and Snake, made up the
+sum total of the casualties on the part of the Diamond X Second outfit.
+</P>
+
+<P>
+"But they're marked!" shouted Yellin' Kid as he and the others rode
+back to camp. "I got one, I'm sure!"
+</P>
+
+<P>
+"I fired low, after I saw they were doing the same, and I saw one
+nearly slump out of his saddle," declared old Billee.
+</P>
+
+<P>
+"I'd like to know if they were any of the Hank Fisher or Del Pinzo
+gang," said Bud.
+</P>
+
+<P>
+"I wouldn't put it past them," asserted Snake. "We'll ride over t'
+Hank's place, casual like, t'-day, an' see if any of his men are hurt."
+</P>
+
+<P>
+Snake spoke rightly of "to-day," for it was getting sunrise-light when
+the battle was over, and the party returned to the tents near the flume
+reservoir.
+</P>
+
+<P>
+The night of excitement, following the mysterious warning sent by the
+Indian arrow, had ended, and everyone welcomed the hot, fragrant coffee
+made by Buck Tooth.
+</P>
+
+<P>
+When Snake's wound and Billee's scratch had been bandaged, the dead
+calves buried and the best part of the killed steers cut off for fresh
+beef, Bud and his friends took what might be termed an accounting.
+</P>
+
+<P>
+The boy ranchers, with Old Billee, rode back over the ground covered in
+the attack of the night. The veteran cow puncher pointed out where the
+rustlers had ridden into the valley, over a pass that crossed a low
+mountain range, which connected, in a fashion, Buffalo Ridge and Snake
+Mountain. This ridge formed the lower boundary of Bud's range, and
+once the cattle had been driven over this they could easily have been
+hazed to Hank Fisher's Double Z ranch.
+</P>
+
+<P>
+"Well, there's nothing to make sure it was any of Del Pinzo's gang,
+except general suspicion," remarked Bud, as they were about to ride
+back to camp. "What's the matter?" he asked, for, with an exclamation,
+Nort had leaped from his saddle. The eastern lad was picking up
+something from the ground that had been so lately trampled by steers
+and horses.
+</P>
+
+<P>
+"Look!" exclaimed Nort, and he held up a branding iron.
+</P>
+
+<P>
+"One of ours?" asked Bud, in rather a commonplace voice.
+</P>
+
+<P>
+"Not exactly," Nort answered. "It's marked with a double Z!"

+QUEER ACTIONS
+</H3>
+
+<P>
+What effect this announcement had on Dick and Bud can easily be
+imagined. Both leaped from their saddles, as Nort had done, and
+gathered close to him as he held the branding iron in his hand.
+</P>
+
+<P>
+It was of the usual type, an iron plate, which had been cast in a
+mould, so that the device&mdash;two Z letters&mdash;formed a depression in the
+smooth surface of the iron plate. On the outer edge was a circle, so
+that when the brand was heated, and pressed on the hide of a steer,
+calf or maverick it would burn the impression of a double Z inside a
+ring&mdash;the mark of Hank Fisher's cattle.
+</P>
+
+<P>
+"Whew!" exclaimed Dick. "This makes it look bad for them, Bud!"
+</P>
+
+<P>
+"Oh, not necessarily, though I'm glad we found it," spoke the western
+lad.
+</P>
+
+<P>
+"Why isn't it suspicious?" asked Nort, whose high hopes had been rather
+dashed by Bud's somewhat cool reception of Dick's statement.
+</P>
+
+<P>
+"Oh, it's <I>suspicious</I> all right!" Bud hastened to say, "and don't
+imagine I'm making light of you finding this, Nort! I'm mighty glad
+you did! Only we can't make it look bad for Hank Fisher, or the Double
+Z crowd unless we can fasten this on them."
+</P>
+
+<P>
+"You mean we can't prove they dropped it here during the raid last
+night?" asked Nort, as he vaulted into the saddle.
+</P>
+
+<P>
+"That's it," spoke Bud. "It does look suspicious, I'll admit. But you
+see while this is our range, we couldn't make a fuss just because some
+cowboy from Double Z rode over it. That wouldn't be right. And what's
+to hinder this having been dropped by some cowboy who was merely riding
+over our range?"
+</P>
+
+<P>
+"That's possible," admitted Dick.
+</P>
+
+<P>
+"But I don't believe it," asserted Nort.
+</P>
+
+<P>
+"Nor I," chimed in Bud. "But you got to go slow in making accusations
+out west, unless you're ready to back your opinion up with a gun; and
+we don't want to do that."
+</P>
+
+<P>
+"No," Nort admitted. "But Old Billee and Snake said they were going to
+ride over to Double Z to-day, to sort of size up the situation. So
+what's to prevent 'em taking this branding iron along and asking,
+casual like, if they don't want it back?"
+</P>
+
+<P>
+"Nothing to stop that," said Bud with a grin. "In fact that's just
+what we'll do. Come on, we'll hit the trail for the camp and make a
+sort of raid on Double Z&mdash;only we'll make it to-morrow instead of
+to-day, as it's too late for a long ride."
+</P>
+
+<P>
+There were murmurs of surprise and excitement at the camp, when the
+boys rode in with the Double Z branding iron that Nort had picked up at
+the scene of the raid.
+</P>
+
+<P>
+"They dropped that last night, sure as horned toads!" cried Snake
+Purdee, whose wound was excuse enough for not being out on duty.
+</P>
+
+<P>
+"I reckon," agreed Pocut Pete, who likewise was off duty. "Let's see
+that," and he reached for the iron which had a wooden handle to enable
+a cowboy to manipulate the marker when the branding end was hot.
+</P>
+
+<P>
+Bud, so Nort and Dick thought, looked rather curiously at Pocut Pete
+while the latter was examining the iron. And when the strange
+cowboy&mdash;strange in the sense that he had not been long in Mr. Merkel's
+service&mdash;took out his knife and began whittling away at the wooden
+handle, Bud uttered a sharp cry of:
+</P>
+
+<P>
+"Stop!"
+</P>
+
+<P>
+"What's the matter?" asked Pocut Pete, with an assumption of innocence,
+which was so plainly an assumption that Nort and Dick exchanged rapid
+glances.
+</P>
+
+<P>
+"Don't cut off those initials!" went on Bud. "Maybe by them we can
+tell who owns the iron."
+</P>
+
+<P>
+"Initials!" exclaimed Pocut Pete. "I don't see any initials!"
+</P>
+
+<P>
+"There they are," and Bud pointed to some, rather faintly cut, on a
+flat place in the handle. "E. C. are the letters, though I don't know
+anybody with them at Double Z."
+</P>
+
+<P>
+"I don't, either," said Pocut Pete. "In fact, I didn't see them
+letters, Bud. I was just whittling the handle to see what kind of wood
+it was. Thought maybe I could tell by that."
+</P>
+
+<P>
+"All right," spoke Bud, as he again assumed charge of the branding
+iron. And Pocut Pete, with a sharp look at the young rancher, went out
+to the corral where the spare ponies were kept.
+</P>
+
+<P>
+"Was he really trying to cut out those initials?" asked Nort, as the
+three boy ranchers passed on to the grub tent, for it was the joyful
+time to eat&mdash;one of the three joyful times that came each day.
+</P>
+
+<P>
+"I wouldn't say he was doing it <I>deliberately</I>," spoke Bud, "but he
+certainly <I>was</I> whittling near those letters. And if he had cut them
+off the owner of the branding iron could easily claim it wasn't his."
+</P>
+
+<P>
+"That was queer," declared Dick.
+</P>
+
+<P>
+"Very," assented Bud. "In fact Pocut Pete has acted queer ever since
+he's been here. I don't like him, and as soon as dad has another
+puncher to spare I'm going to ask for a change."
+</P>
+
+<P>
+The remainder of that day and the night passed quietly. There was no
+other alarm, and riding herd was an easy task. Nor was there any
+stoppage of the water, which ran freely out through the pipe from the
+underground tunnel as though there had never been any interruption of
+its very necessary service.
+</P>
+
+<P>
+"Well, let's go!" exclaimed Bud next day, as he and his cousins saddled
+their ponies, and Old Billee called for Yellin' Kid to help catch a
+rather frisky pinto that the old cowboy was going to ride.
+</P>
+
+<P>
+"Over to Double Z?" asked Nort.
+</P>
+
+<P>
+"Yes, we'll take a sort of a look around their place, and hand back
+this iron," went on Bud, as he slung the implement to his saddle by a
+loop of his lariat.
+</P>
+
+<P>
+The ride to Double Z was pleasant enough, for soon the boys and Old
+Billee struck the hill trail, where it was cooler than down in the
+valley.
+</P>
+
+<P>
+But if they hoped to discover any incriminating evidence at Hank
+Fisher's place they were disappointed.
+</P>
+
+<P>
+There was no sign of Del Pinzo&mdash;in fact that wily Mexican half-breed
+was seldom at the ranch proper. Nor was Hank at home. But his foreman
+met the boys and Old Billee.
+</P>
+
+<P>
+"Hear about the racket over at our place?" asked Bud, easily enough,
+but with a beating heart. He and his cousins looked around for any
+signs of wounded men, but saw none.
+</P>
+
+<P>
+"What racket?" asked Ike Johnson, the foreman.
+</P>
+
+<P>
+"Rustlers," put in Old Billee. "They scratched me, shot up Snake
+Purdee and dropped this&mdash;or at least we found this after the mix-up
+when we'd druv 'em off!" and he took the branding iron from Bud's
+saddle loop.
+</P>
+
+<P>
+"You don't mean to say&mdash;&mdash;" began Ike, with an ugly tone to his voice.
+</P>
+
+<P>
+"Don't mean t' say nawthin'!" drawled Old Billee. "That's one of your
+irons, I take it."
+</P>
+
+<P>
+"Yes, it is," growled the foreman slowly. "But that don't mean&mdash;&mdash;"
+</P>
+
+<P>
+"Course it don't!" pleasantly interrupted the old cowboy, giving the
+young ranchers a slight signal to let him do the talking. "One of your
+boys dropped it, likely, ridin' short-cut across our place, Ike."
+</P>
+
+<P>
+"Yes, I remember now, Ed Carr said he lost his. This is it," and the
+foreman of Double Z pointed to the initials.
+</P>
+
+<P>
+"Well, tell Ed&mdash;is he here now?" asked Billee, interrupting himself.
+</P>
+
+<P>
+For an instant&mdash;and for an instant only&mdash;Ike Johnson hesitated. Then
+he answered:
+</P>
+
+<P>
+"No, Ed's ridin' line. I'll give him this when he comes in."
+</P>
+
+<P>
+"All right," spoke Billee, with a smile. "We was just passin' and
+stopped with it. How's things, Ike?" he asked with an effort to be
+friendly.
+</P>
+
+<P>
+"Oh, so-so! Might be wuss, an' might be a hull lot better."
+</P>
+
+<P>
+"I reckon it's that way all over," Billee made answer. "Well, boys,"
+he resumed, "might as well ride back. You gittin' all the water you
+can use from Pocut River, ain't you, Ike?" he asked, turning in his
+saddle.
+</P>
+
+<P>
+"Better ask th' boss about that," was the sullen retort. "I reckon
+he'll have suthin' t' say, soon, that you Diamond X folks won't like!"
+</P>
+
+<P>
+"Is that a threat?" asked Bud quickly.
+</P>
+
+<P>
+"Easy, son, easy!" cautioned Old Billee.
+</P>
+
+<P>
+"You can make anythin' yo' like of it!" sneered the Double Z foreman.
+</P>
+
+<P>
+And then the boy ranchers and Old Billee rode off.
+</P>
+
+<P>
+"Well, we didn't find out much," said Nort, when they were on the
+homeward trail.
+</P>
+
+<P>
+"No, but we let 'em know we found that branding iron, and that we knew
+where it belonged," spoke Bud. "That's something!"
+</P>
+
+<P>
+They were rather late getting back to camp, for Dick's pony went lame,
+and the others accommodated their pace to his. It was dusk when the
+little party hit the borders of Diamond X Second, and saw the grazing
+cattle.
+</P>
+
+<P>
+Bud saw something else, for as he rode ahead he called:
+</P>
+
+<P>
+"What's he doing?"
+</P>
+
+<P>
+"Who?" asked Nort.
+</P>
+
+<P>
+"Pocut Pete," replied Bud. "Looks like he was trying to brand one of
+our cattle with his knife! Look! That's mighty queer!"
+</P>

+"GERMS!"
+</H3>
+
+<P>
+Pocut Pete did not become aware of the approach of the boy ranchers and
+Old Billee until they were almost upon him. He was either so intent on
+what he was doing, or else the fact that the ponies were on a grassy
+footing made their advance practically noiseless, that, seemingly, he
+heard nothing.
+</P>
+
+<P>
+However it was, the cowboy, about whom Bud entertained suspicious, kept
+on with what he was doing&mdash;something strange to one of the
+milder-tempered steers. Something "mighty queer," as Bud had said in a
+whisper to his chums. Which whisper accounted for the fact that Pocut
+Pete had not heard the voice.
+</P>
+
+<P>
+So it was not until their shadows, mingling with those of the
+descending night, fell athwart him that the cowboy looked up with a
+start.
+</P>
+
+<P>
+"Oh!" exclaimed Pocut Pete, and then Bud and the others saw that he had
+a knife in his hand, and something else. Something that glistened when
+Old Billee struck a match to light his pipe. For the old cowboy had,
+long ago, passed up the inevitable paper cigaret, and used the more
+sedate form of the weed.
+</P>
+
+<P>
+"What's the idea?" asked Bud, and his question seemed to give Pocut
+Pete a chance to pull himself together, to answer with more coolness
+than he had exhibited by his first exclamation.
+</P>
+
+<P>
+"This steer had some sort of a growth on his shoulder&mdash;like a wart,"
+explained the cowboy. "I was just seeing if I could cut it off."
+</P>
+
+<P>
+"You'd better be careful!" warned Old Billee.
+</P>
+
+<P>
+"Why?" asked Pocut Pete so quickly that the other's remark might have
+well carried a threat, which, in the tone Billee used it, did not.
+</P>
+
+<P>
+"You may get horned," went on the veteran cow puncher. For many of the
+cattle on the range of Bud and his cousins "wore their horns long," so
+to speak. Gradually the dehorning system was spreading through the
+west, but such an innovation, found to be most practical from all
+standpoints, took time to grow.
+</P>
+
+<P>
+"Oh, this chap isn't dangerous," went on Pocut Pete with a laugh,
+closing his rather large pocket knife with a snap. "All the same, if
+you don't want me to snip off that wart I won't."
+</P>
+
+<P>
+"I wouldn't," said Bud. "Not but what I'm glad to have you take an
+interest in the cattle," he went on, "but cutting one with a knife
+might bring on blood poisoning."
+</P>
+
+<P>
+"Yes, an' jabbin' a knife into one might set it wild, an' it would rush
+off an' start a stampede," said Billee.
+</P>
+
+<P>
+"I realized that," admitted Pocut Pete, "so that's why I didn't do it
+until I got this steer off by himself."
+</P>
+
+<P>
+He spoke this truly enough, for the lone animal he had been "operating"
+on was some distance from the main herd.
+</P>
+
+<P>
+"I never saw a wart on a steer," spoke Bud, as he urged his pony nearer
+to where the strange cowboy stood on the ground close to the beef
+animal. "It's queer&mdash;&mdash;"
+</P>
+
+<P>
+There was a sudden movement. Pocut Pete leaped back and the steer, as
+though taking fright at Bud's advance, lowered its head, and, with a
+loud bellow, sprang away.
+</P>
+
+<P>
+"I told you so!" called out Old Billee. "You might 'a' got horned,
+Pete!"
+</P>
+
+<P>
+"Oh, I was watching," came the answer. "Yes, warts do, sometimes, come
+on cattle," he went on. "I've cut off lots of 'em. Some beef men
+won't pass 'em if they have any. I thought I was doing you a favor."
+He spoke in an injured tone of voice.
+</P>
+
+<P>
+"Well, maybe you were," admitted Bud. "First I thought you were
+someone else."
+</P>
+
+<P>
+"One of the Double Z bunch?" asked Pocut Pete with a laugh. "Did you
+find out anything over there?" he inquired as he caught his pony, which
+had been standing near-by, and leaped into the saddle.
+</P>
+
+<P>
+"Nary a thing," voiced Old Billee.
+</P>
+
+<P>
+And then, as the group, Pocut Pete included, headed back for camp, the
+old cowboy broke into song, roaring out:
+</P>
+
+<P CLASS="poem">
+"Send me a letter, kid,<BR>
+Write it yo'self!<BR>
+Put in some news of th' city.<BR>
+For it's lonesome out here,<BR>
+'Neath th' blue, starry sky,<BR>
+An' cowboys don't get any pity!"<BR>
+</P>
+
+<BR>
+
+<P>
+"What's struck you?" laughed Bud.
+</P>
+
+<P>
+"Oh, I feel sorter so-so," affirmed Old Billee. "We're in for a storm,
+I reckon."
+</P>
+
+<P>
+"And that's your weather indication!" chuckled Nort.
+</P>
+
+<P>
+"Yeppy," agreed the veteran, and he broke into another verse of the
+interminable song&mdash;one of the series that cowboys love to warble.
+</P>
+
+<P>
+"What do you think of Pocut Pete?" asked Dick of Bud in the seclusion
+of their own tent that night.
+</P>
+
+<P>
+"Oh, I don't know what to think," was the answer. "I did have him down
+for a drinker, or a doper, but he doesn't seem to be either, and he
+does his work well. Only I don't know what to make of his actions
+to-night. Warts! On a steer! That sounded fishy to me!"
+</P>
+
+<P>
+"Same here!" agreed Dick.
+</P>
+
+<P>
+But as several days passed, and nothing more suspicious occurred, the
+action of Pocut Pete was rather forgotten. Nor was there any further
+trouble with the rustlers, or the lack of water. In spite of the
+warnings and veiled threats that had been received, the black pipe
+still spouted into the reservoir.
+</P>
+
+<P>
+And then, like lightning out of a clear sky, came a bolt that gave the
+boy ranchers a shock.
+</P>
+
+<P>
+Old Billee riding in from off the distant range one day, called to Bud
+who was opening some of the reservoir gates to let water run to a
+distant trough for the cattle.
+</P>
+
+<P>
+"Bad business, Bud!" exclaimed the veteran.
+</P>
+
+<P>
+"What's that?" asked the lad, with an instinctive glance at the black
+pipe, whence the water spouted. His first thought was of that.
+</P>
+
+<P>
+"There's five of your steers dead, over near the last water trough!"
+was the answer.
+</P>
+
+<P>
+"Steers dead!" gasped Bud. "Rustlers?" he asked, quickly.
+</P>
+
+<P>
+"Don't 'pear to be," Billee answered. "There isn't a mark on 'em.
+Maybe it's glanders. Better get Doc. Tunison right over."
+</P>
+
+<P>
+Which Bud did, by telephone.
+</P>
+
+<P>
+The veterinarian, who looked after the health of cattle in that
+vicinity, appeared in due season. Bud, with his cousins and Old Billee
+went out to where the dead cattle lay, now stiff and stark. Some
+buzzards flopped heavily off as the party approached.
+</P>
+
+<P>
+"Hum!" mused Dr. Tunison as he began his examination. It did not take
+him long to complete it. "I thought so," he remarked, as he looked at
+Bud.
+</P>
+
+<P>
+"What is it?"
+</P>
+
+<P>
+"Germs!" was the answer. "The epidemic's struck you, Bud!"

+ROPED!
+</H3>
+
+<P>
+Like a blow struck came that announcement to Bud Merkel. And to his
+chums and partners in their first small venture as boy ranchers on
+their own responsibility, the announcement of the veterinarian was
+staggering.
+</P>
+
+<P>
+"Germs!" exclaimed Nort.
+</P>
+
+<P>
+"Epidemic!" voiced Dick.
+</P>
+
+<P>
+"Has it really struck here&mdash;the same disease that was among dad's
+cattle?" asked Bud, as though hoping there might be some mistake.
+</P>
+
+<P>
+"It's here all right," went on Dr. Tunison, rising from his stooping
+position beside a dead steer. He looked about for a puddle of water in
+which to wash his hands, and, having completed the operation, using a
+disinfectant from a bottle he produced, he added: "Better fence off
+this puddle, Bud. If any of your other cattle happen to drink here
+they'll get the disease, too, and bump off."
+</P>
+
+<P>
+That was his way of saying that the steers would die.
+</P>
+
+<P>
+"I'll do that!" declared Bud. "We can cut the water off from this part
+of the range. But what causes the epidemic, Doc? Dad was careful not
+to send me any of his infected cattle from Square M, and he said you'd
+examined all that came, and they didn't have any of the trouble."
+</P>
+
+<P>
+"They didn't," declared the veterinarian. "I examined them all, and
+nothing was wrong with them. But this epidemic is a germ disease, Bud,
+and we don't exactly know how the germs are carried. It may be
+something the cattle eat; the bunch grass or other fodder, in the
+water; or it may come out of the air. All we know is that certain
+germs, in some, as yet unknown, way, enter into the system of the
+steer. They get into the blood through the mouth or nostril, or
+perhaps from a scratch or cut. And once the germs are there, so rapid
+is the action that the animals die over night&mdash;as yours have done, and
+as your father's did."
+</P>
+
+<P>
+"Has dad lost any more?" asked Bud.
+</P>
+
+<P>
+"Not that I've heard of. In fact I thought by his action, in sending
+the healthy animals of his Square M herd here, and to his other
+ranches, that he'd gotten the best of it. But now the epidemic breaks
+out here. I can't understand it!"
+</P>
+
+<P>
+The veterinarian stood looking down at the dead animal, while the
+buzzards patiently waited nearby for the feast they knew belonged to
+them. Evidently they were not fearful of germs.
+</P>
+
+<P>
+"What's that funny smell?" suddenly asked Nort.
+</P>
+
+<P>
+"That? Oh, it's the smell characteristic of the disease," replied Dr.
+Tunison. "Not very pleasant. I got some of the pus on my
+hands&mdash;that's why I washed and disinfected them. Well, Bud, I'm afraid
+you're in for it!"
+</P>
+
+<P>
+"You mean the epidemic may run through all my stock?" asked the boy
+rancher, anxiously.
+</P>
+
+<P>
+"It may, and that's the reason I'm putting you on your guard. But
+let's hope for the best. We'll act promptly. Fence this place off, or
+don't let any more water here, where other cattle can drink from the
+pool, that must, of necessity, be contaminated, now that I washed my
+hands in it, if for no other reason. Also separate the other cattle
+into as many herds as you can handle. In this way, if the epidemic
+gets among one bunch, you don't stand to lose so many. This is about
+all you can do."
+</P>
+
+<P>
+"No preventative measures?" asked Bud.
+</P>
+
+<P>
+"No. If the cattle remain healthy they may resist the germs. Nature
+sometimes provides her own remedies. She'll have to, in a case like
+this, where so little is known about this malady that no cure is yet
+available to science."
+</P>
+
+<P>
+"That sure is a funny smell&mdash;I don't like it!" said Nort again.
+</P>
+
+<P>
+"No, it isn't very pleasant," agreed the veterinarian.
+</P>
+
+<P>
+And then Bud, who had been in a serious, brown study seemed, for the
+first time, to become aware of the evil odor.
+</P>
+
+<P>
+"That smell! That smell!" he cried. "I've smelled it before!"
+</P>
+
+<P>
+"Not unless you came in contact with the germs," spoke Dr. Tunison.
+"Where did you smell it, Bud?"
+</P>
+
+<P>
+But, as suddenly as he had spoken, Bud Merkel became silent. He seemed
+to be thinking deeply, and as he turned aside he said:
+</P>
+
+<P>
+"Oh, maybe it was when Old Billee rode in to tell me he had seen these
+dead steers."
+</P>
+
+<P>
+"Possibly," admitted the veterinarian. "The smell is very
+characteristic, as I said. But you'd better arrange to bury these
+animals, Bud."
+</P>
+
+<P>
+"There isn't any danger&mdash;I mean to humans; is there?" Bud asked. "If
+there is we'll let 'em stay here. The buzzards will make short work of
+'em."
+</P>
+
+<P>
+"No, there's no danger to man, even in directly handling the germs.
+That has been proved," said Dr. Tunison. "But if you let the cattle
+lie here, and the buzzards eat 'em, in some manner the disease may be
+carried to your other cattle. Best bury 'em, and fence off this
+water-hole."
+</P>
+
+<P>
+Which was done. So the evil-looking buzzards were deprived of a feast,
+and flapped mournfully away.
+</P>
+
+<P>
+There were anxious days that followed the appearance of the epidemic
+among the cattle of the boy ranchers. I speak of the cattle as their
+own, and they were, in a sense. For though, of course, Mr. Merkel
+really owned Flume Valley, and put up the cash to start the boys in
+business, he had determined that they should run the place as though it
+was their own. They must stand or fall by what happened. It was the
+only real way to start them in the way of becoming cattlemen, he
+decided.
+</P>
+
+<P>
+So, though the boys were young, possibly the youngest ranchers in that
+part of the west, they were in earnest and accepted all the
+responsibilities that went with the venture.
+</P>
+
+<P>
+Bud was very thoughtful those anxious days. There was hard work for
+all, since dividing the doubled herds into small units meant that each
+cowboy, including Bud, Nort and Dick, had to look after a certain
+number day and night. But no one shirked, even Buck Tooth working
+unusually hard in addition to doing the cooking. Though Indian braves
+are constitutionally opposed to labor, Buck Tooth made an ideal
+herdsman.
+</P>
+
+<P>
+Not as much time was spent in camp as had formerly been the case, as
+the boy ranchers and their older helpers were more often out riding
+herd. But occasionally many of them gathered at the tents to compare
+notes and "feed up," as Snake put it. His wound, received in the fight
+with the rustlers, had healed.
+</P>
+
+<P>
+"Some day we'll have regular ranch houses here instead of just a camp,"
+Bud said, as he was riding back one day to look after the herd he had
+assigned to himself.
+</P>
+
+<P>
+"Oh, this isn't so bad," spoke Nort.
+</P>
+
+<P>
+"Real jolly, I call it!" added Dick.
+</P>
+
+<P>
+"If only the water supply keeps up, and no more epidemic comes, we'll
+be all right," Bud announced. "At the same time I can't be sure of
+either."
+</P>
+
+<P>
+This was true. Though the water flowed merrily on since the time the
+lads had penetrated the length of the tunnel, there was always an
+uneasy feeling, on the part of the boy ranchers and their friends, that
+it might stop at any time.
+</P>
+
+<P>
+"And when it dries up again," Bud declared, "I'm not going to be
+satisfied until I find out what makes it quit flowing!"
+</P>
+
+<P>
+"That's the idea!" added Nort. "We'll solve the mystery!"
+</P>
+
+<P>
+As the days passed, and no more cattle were found ill or dead from the
+epidemic, the hopes of the boy ranchers began to rise. Had they caught
+the malady in time? Could it be stamped out by the burial of the five
+steers? Time alone&mdash;and a longer time than had so far elapsed&mdash;could
+tell.
+</P>
+
+<P>
+Bud, Nort and Dick each had charge of a herd, the three bunches of
+cattle being pastured on adjoining areas of rich grass.
+</P>
+
+<P>
+But the distances separating them were not so great but that Bud and
+his cousins could exchange visits. And it was on one of these
+occasions that there occurred something which cleared up, in part at
+least, the mystery hanging over Flume Valley.
+</P>
+
+<P>
+The boy ranchers were about to part for the evening, having spent the
+afternoon together over "grub," cooking at an open fire; and Nort and
+Dick were preparing to ride back to their herds, Bud being on the
+ground, so to speak, where he would "bunk" for the night.
+</P>
+
+<P>
+As they rode down into a little swale amid the gathering shadows of the
+night, a bunch of cattle moved uneasily along ahead of them, and as the
+steers parted there was disclosed in their midst the forms of a man and
+a horse.
+</P>
+
+<P>
+"Who's that?" suddenly asked Dick.
+</P>
+
+<P>
+"It isn't one of our boys," declared Nort.
+</P>
+
+<P>
+Bud suddenly sat upright in his saddle. He breathed deeply, and then
+quickly spurred forward. His cousins saw him swinging his lariat
+around his head.
+</P>
+
+<P>
+In an instant it went swishing through the air, and, a moment later, as
+the coils settled about the figure of a man who started to leap for his
+pony, Bud let out a yell, shouting:
+</P>
+
+<P>
+"Roped! Roped, by Zip Foster!"

+
+<H3 ALIGN="center">
+AN EXPEDITION IN THE DARK.
+</H3>
+
+<P>
+There was a confusion of rope and man. Sock, Bud's pony, braced his
+feet, including the white one that gave him his name, and the lariat
+tightened. There was a scurrying among the cattle, and the lone pony,
+without a rider, galloped off.
+</P>
+
+<P>
+Nort and Dick, taken by surprise, had reined their steeds to a stop
+when they saw Bud lassoing the unknown man, but now they spurred up to
+their cousin.
+</P>
+
+<P>
+"What is it?" demanded Nort.
+</P>
+
+<P>
+"Who is he?" Dick wanted to know.
+</P>
+
+<P>
+At that instant a shot cracked, and the fast-gathering darkness was cut
+by a sliver of flame.
+</P>
+
+<P>
+"Trying that, are you!" angrily shouted Bud, and he backed his pony
+quickly, pulling the roped man along the ground, until the prostrate
+figure let out a yell.
+</P>
+
+<P>
+"My hands are up!" came desperately out of the darkness.
+</P>
+
+<P>
+"They'd better be!" retorted Bud. "Can you get off and tie him, Nort?"
+the boy rancher called to his cousin. "Get out your gun, Dick, and
+cover him! He's going to be a bad actor, I'm saying!"
+</P>
+
+<P>
+"I'm through!" came the sullen response from the man on the ground.
+"My gun went off by accident."
+</P>
+
+<P>
+"Such <I>accidents</I> aren't healthy around here," grimly spoke Bud. "Get
+at him, fellows!"
+</P>
+
+<P>
+"Who is he?" asked Nort, as he slipped from his pony, throwing the
+reins forward and on the ground as notice that the animal was to stand.
+</P>
+
+<P>
+"And what's that funny smell?" asked Dick. "It's like&mdash;like the time
+we found the five dead steers!"
+</P>
+
+<P>
+"Yes, and there'll be more dead steers as the result of this!" said
+Bud, and there was a choking in his voice.
+</P>
+
+<P>
+A moment later Dick and Nort were standing over the prostrate figure of
+Pocut Pete. His arms were bound firmly to his sides by the tight coil
+of the lariat, held taut by Bud, and the other boys could see that the
+cowboy's gun had slipped from its holster and lay some distance away
+from him. Nort picked up the gun, and then, with quick motions, he and
+Dick bound some coils of Bud's rope around the rascal's feet.
+</P>
+
+<P>
+All the fight seemed taken out of him. Without his gun, down on the
+ground and his pony out of reach&mdash;he lacked all the prime requisites of
+a cowboy. There was no escape, covered as he was by Bud, who had drawn
+his own .45, and Pocut Pete "jest natcherly caved in," as Old Billee
+described it later.
+</P>
+
+<P>
+"Caught you at it, just as I thought I would!" said Bud, when Pete was
+bound and hoisted up on his horse by the boys.
+</P>
+
+<P>
+"Go on! Get it over with," was the grim answer. "I know when the game
+is played out, and it was a dirty game from the start. I'd never have
+opened it only I was desperate for money, and he offered me a lot."
+</P>
+
+<P>
+"I know who you mean," said Bud. "It sure was a dirty game; and the
+worst of it is that it isn't over yet. That epidemic may spread all
+through our stock!"
+</P>
+
+<P>
+Pocut Pete returned no answer as the boys started with him in the
+direction of the camp.
+</P>
+
+<P>
+"What was he doing&mdash;trying to cut more warts off your cattle?" asked
+Dick.
+</P>
+
+<P>
+"Warts!" cried Bud indignantly. "He was infecting them with the germs
+of that disease! Don't you smell the rotten stuff?"
+</P>
+
+<P>
+"Oh!" exclaimed Nort. "So <I>that's</I> the game?"
+</P>
+
+<P>
+"Yes," spoke Bud bitterly. "I wish I'd acted sooner, when I began to
+suspect him! But I didn't think any one would play a trick like
+this&mdash;especially on some one who never had harmed him."
+</P>
+
+<P>
+"Has he been infecting your cattle?" asked Nort.
+</P>
+
+<P>
+"Sure!" answered Bud. "I've got the goods on him! He had some thin
+glass bottles, with some sort of germ-dope in them. He cut, or
+scratched, the cattle and poured this stuff in the sore. That's how my
+steers got it, and not from being infected by those dad sent over. Oh,
+it sure is a rotten game, just when we were starting, too!"
+</P>
+
+<P>
+"He ought to be shot!" indignantly voiced Nort.
+</P>
+
+<P>
+"Or strung up!" added Dick.
+</P>
+
+<P>
+"I don't care what they do to him!" said Bud. "I'm going to turn him
+over to Old Billee and the boys!"
+</P>
+
+<P>
+"Don't do that!" begged the bound figure of Pocut Pete. "They&mdash;they
+may lynch me. Take me right to the sheriff!"
+</P>
+
+<P>
+"Too far," said Bud shortly. "I don't care what the boys do to you!
+I'm through!"
+</P>
+
+<P>
+The prisoner vainly struggled with his bonds, but they held firm.
+</P>
+
+<P>
+It need not be written that there was a surprised bunch of cow punchers
+who gathered in the camp of the boy ranchers a little later, when Pocut
+Pete was delivered to them. Indignant voices and looks were noted on
+all sides as his crime was recounted by Bud.
+</P>
+
+<P>
+In brief it was this:
+</P>
+
+<P>
+From the time of Pocut Pete's arrival Bud had taken a dislike to him,
+and had suspected him, wrongly it appeared now, of being an addict to
+some form of drug, slangily termed "dope." For he had found fragments
+of thin-glass bottles, and had discovered in part of a broken phial,
+the same evil-smelling mixture that, later, was associated with the
+diseased cattle.
+</P>
+
+<P>
+Then Bud did not know enough of the danger to act promptly, and even
+when Pocut Pete was discovered, "cutting a wart off a steer," as he
+falsely said, Bud did not know what to make of that. An older person
+might have been suspicious enough to have acted with more promptness,
+but Bud, naturally, had lots to learn.
+</P>
+
+<P>
+However, as appeared later, Pocut Pete had secured from some of the
+disease-killed cattle some pus, filled with millions of germs. This
+unpleasant mixture he kept in tiny phials.
+</P>
+
+<P>
+How he learned that to inject some of this pus under the hide of a
+steer would infect the animal, not only causing it to die of the
+disease, but to transmit it to others, is not vital to the story.
+Sufficient that Pocut Pete did know this.
+</P>
+
+<P>
+And he put his evil knowledge to evil use. He was caught by Bud, Nort
+and Dick in the very act of infecting some of Bud's steers. For when
+search was made in the morning, at the scene of the capture, broken
+bits of phials were discovered, some with that vile, yellow substance
+on them. And an inspection of the cattle showed several with cuts on
+their flanks, into which cuts, it was assumed, the germs had been
+injected, or rubbed.
+</P>
+
+<P>
+These animals were at once isolated, to determine what would happen to
+them. The ground near where Pocut Pete had carried on his nefarious
+operations was sprayed with disinfectants, and the cattle that had been
+with those he inoculated were also herded by themselves.
+</P>
+
+<P>
+These were all the precautions that could be taken, and then Pocut Pete
+was hurried off to the nearest jail, there to await trial.
+</P>
+
+<P>
+"But what set him up to such vile work?" asked Nort, when the prisoner
+had been taken from camp.
+</P>
+
+<P>
+"What else but the desire of Hank Fisher to see our stock-raising
+experiment fail?" countered Bud. "This is the doing of those
+scoundrels at Double Z. I only wonder that Del Pinzo wasn't in on the
+game."
+</P>
+
+<P>
+"He may be yet," said Dick.
+</P>
+
+<P>
+"Well, we'll be on the watch from now on&mdash;doubly on the watch,"
+asserted Bud. "They won't put anything like this over on us again!"
+</P>
+
+<P>
+"Not if we know it!" joined in his cousins.
+</P>
+
+<P>
+It could not be determined, for several days, what the turn would be in
+the case of the cattle into which Pocut Pete had injected germs of the
+disease. Dr. Tunison was sent for, but said he could do nothing more
+than had been done.
+</P>
+
+<P>
+"You'll just have to wait and see how many will die," he told Bud.
+"You've done all you could by isolation. And there's one thing in your
+favor. No more of your cattle have been infected by those five that
+first died. We caught that outbreak in time. And if it proves that
+Pocut Pete is the sole source of infection on your ranch, it means that
+only those he managed to cut in his last operation will die."
+</P>
+
+<P>
+But it took time to determine this, and while waiting for the outcome
+something else happened which, though it seemed to involve tragedy at
+the time, really resulted in clearing up the mystery and ending the
+water fight at Diamond X.
+</P>
+
+<P>
+One morning, about a week after the roping of Pocut Pete, when the boy
+ranchers and their friends were assembled in camp, preparatory to
+starting out on their rounds of riding herd, Buck Tooth, who had gone
+to the reservoir to fish, came running down to the tents much excited.
+</P>
+
+<P>
+"He must have caught a big one!" commented Old Billee.
+</P>
+
+<P>
+But it was not fish that had aroused the old Indian.
+</P>
+
+<P>
+"Water stop! Water him stop all time!" he yelled.
+</P>
+
+<P>
+"What's that?" shouted Bud. "Isn't the pipe running?"
+</P>
+
+<P>
+"No run!" answered Buck Tooth briefly. "All gone!"
+</P>
+
+<P>
+"More trouble!" commented Bud. And then, with a grim tightening of his
+lips, he added: "This time we'll get to the bottom of the mystery!"
+</P>
+
+<P>
+There was no doubt about the fact that the water had stopped running.
+As they all raced up the sloping side of the reservoir they saw only a
+few drops trickling from the pipe.
+</P>
+
+<P>
+"The third time&mdash;I'm going to make it the last if it's possible,"
+declared Bud.
+</P>
+
+<P>
+"What yo' aimin' t' do?" asked Old Billee.
+</P>
+
+<P>
+"Go through the tunnel from end to end, and both sides, and see where
+the water vanished to," was the answer. "We'll get up a regular
+expedition this time, and maybe take a boat. We'll find out what it
+all means."
+</P>
+
+<P>
+"I believe you're right," asserted Snake Purdee. "There's no use
+trying to work Flume Valley if the water supply is goin' to be cut off
+without notice. I'm with you, Bud!"
+</P>
+
+<P>
+"So 'm I!" shouted Yellin' Kid. "Whoop-ee! I'm a lone wolf an' this
+is my turn for makin' a noise! Whoopee!"
+</P>
+
+<P>
+"Let's find out, first, if the water is coming into the pipe from the
+river," suggested Nort.
+</P>
+
+<P>
+"You call up," begged Bud. "I'm going to get ready for this
+expedition. We'll have to start in the dark," he went on, referring to
+the black tunnel that stretched under Snake Mountain. "But we may come
+out into the light. Anyhow, we're going in!"

+INTO THE DEPTHS
+</H3>
+
+<P>
+Preparations for exploring the mysterious tunnel on this occasion were
+much more complete and elaborate than when Bud, Dick and Nort walked
+through it before. And they did not rush off in haste, the moment it
+was discovered that the water no longer came through the reservoir end
+of the pipe line that formed the beginning and end of the old
+underground stream course.
+</P>
+
+<P>
+"There's water enough for nearly a week, anyhow," said Bud, in
+discussing their plans. "And if we can't discover the cause of the
+stoppage inside of that time, and get it turned on again, we may as
+well know that and give up Flume Valley as a bad job."
+</P>
+
+<P>
+"That's right," chimed in Nort.
+</P>
+
+<P>
+"The stoppage is inside the tunnel, that's sure," voiced Dick.
+</P>
+
+<P>
+"Yes," answered his cousin. "The water is running in all right from
+the river."
+</P>
+
+<P>
+This fact had been ascertained by telephone. The water was running
+freely from Pocut River above the dam, and into the pipe that entered
+the side of the mountain.
+</P>
+
+<P>
+Bud's father had been told of the situation, which followed so closely
+on the heels of the discovery of the evil acts of Pocut Pete.
+</P>
+
+<P>
+"Doesn't this sort of set you fellows back so you want to give up
+ranching?" Mr. Merkel asked his son and nephews.
+</P>
+
+<P>
+"Not a bit!" promptly answered Bud.
+</P>
+
+<P>
+"We're going to stick!" added Nort.
+</P>
+
+<P>
+"And find out what makes this water stop," contributed Dick. "We'll
+show up Hank Fisher, Del Pinzo and that other bunch of crooks, too!"
+</P>
+
+<P>
+"I don't see how Hank could have had anything to do with this water
+stoppage," said Mr. Merkel. "Of course it may develop that he hired
+Pocut Pete to infect our cattle, but even that is doubtful. Those
+fellows are pretty cute. Anyhow, Pocut Pete is where he can't do any
+harm for some time. He won't be tried until fall.
+</P>
+
+<P>
+"But it's my idea, boys, that this water stoppage is caused by some
+natural means. We are using an old underground river bed, you realize,
+and there may be what I'd call a 'hole' in it somewhere. The water
+that ought to come to you may drop down that hole."
+</P>
+
+<P>
+"But why doesn't it do it all the while?" asked Dick.
+</P>
+
+<P>
+"That's one of the mysteries," said his uncle, "one that you'll have to
+solve."
+</P>
+
+<P>
+"We went over it all before," spoke Bud, "and we couldn't see even a
+branch passage."
+</P>
+
+<P>
+"Well, some of the men are going with you this time," his father said.
+"They're more used to looking for signs than you fellows are, though I
+must say you've done fine, so far!"
+</P>
+
+<P>
+As Mr. Merkel had stated, it was decided to send several of the cowboys
+with Bud and his cousins on this expedition into the dark tunnel. Old
+Billee, Yellin' Kid and Snake Purdee would be of the party, which would
+thus consist of six.
+</P>
+
+<P>
+In this way, there being safety in numbers, it was hoped that accidents
+might be avoided, or, if they happened, there would be at hand help for
+the unfortunates.
+</P>
+
+<P>
+"If we could only take a boat," said Dick, when the preparations were
+almost completed, "it would be great!"
+</P>
+
+<P>
+"What could we do with a boat in that stream, which is hardly three
+feet wide in places?" asked his brother. A boat had been mentioned in
+the first excitement, however, but the idea was abandoned as
+impracticable.
+</P>
+
+<P>
+"Well, if the flood came, as suddenly as it did when we had to take
+refuge on the ledge, we could float out," answered Dick.
+</P>
+
+<P>
+"A boat to hold six men would be too big to carry," spoke Bud. "Even a
+folding canvas one wouldn't answer. But I know what we can do."
+</P>
+
+<P>
+"What?" asked Nort.
+</P>
+
+<P>
+"We can each take an inner automobile tire. Blown up, they are as good
+as life preservers, and with them fastened to us we can float and be
+carried along by the current, if a flood happens again."
+</P>
+
+<P>
+It was decided that this was a wise precaution to take, and from
+Diamond X some inner tubes were sent over&mdash;old ones that had outlived
+their usefulness on the car, but which still held air, and would, as
+Bud said, make excellent life preservers.
+</P>
+
+<P>
+In order to make a thorough examination it was decided to take food and
+water enough to last the expedition at least two days. It was easy to
+traverse the tunnel in one day, as the boys had proved. But Old Billee
+counseled a slower trip.
+</P>
+
+<P>
+"I wish I could go with you," said Mr. Merkel to the boys, when the
+time came for the start, "but I have a shipment of steers to get off,
+and I want to keep watch of this epidemic. It begins to look as if we
+had gotten the best of it, but I'm taking no chances."
+</P>
+
+<P>
+"Oh, we'll make out all right, Dad," spoke Bud. "Though we would like
+to have you with us. And when we come back we'll either settle, for
+good and all, this fight for water, or we'll abandon Flume Valley!"
+</P>
+
+<P>
+"I'd hate to see you give it up," said the ranchman. "It is an ideal
+place to raise cattle, with the water here. But without it, of course,
+there's no use thinking of it. Well, good luck to you," he called, as
+he turned to go back to Diamond X proper.
+</P>
+
+<P>
+As he had said, there had been no further outbreak of the epidemic
+among the cattle of the boy ranchers. The steers which Pocut Pete had
+cut, injecting into them the pus and germs, died, however. And there
+were more of these than Bud and his cousins had counted on.
+</P>
+
+<P>
+But if they lost no more than this half-score, and could get the water
+back, all might yet be well.
+</P>
+
+<P>
+The water in the reservoir had gone down several feet when the
+expedition started into the tunnel. Much of the fluid had to be drawn
+off to water the thirsty cattle, for it was the height of summer now,
+and the heat, in the middle of the day, was terrific.
+</P>
+
+<P>
+But there was still enough of the supply to last for several days.
+Then, if Bud and his companions could not discover the secret of the
+stoppage, and get the water to running again. Flume Valley would have
+to be abandoned.
+</P>
+
+<P>
+"Well, I can't see that we can do any more," spoke Bud.
+</P>
+
+<P>
+"No; you've got things as well fixed as possible," agreed Old Billee.
+</P>
+
+<P>
+"Can't tell when you'll see us again," said Dick to the remaining
+cowboys gathered about the reservoir end of the tunnel to see the
+expedition start in.
+</P>
+
+<P>
+"Well, good luck, anyhow!" came the answer.
+</P>
+
+<P>
+A number of punchers had been sent over to Flume Valley from Diamond X
+and Triangle B to replace Yellin' Kid, Billee and Snake Purdee who were
+to accompany the boy ranchers.
+</P>
+
+<P>
+Suddenly Yellin' Kid broke into song:
+</P>
+
+<P>
+"Leave me alone with a rope an' a saddle,<BR>
+Fold my spurs under my haid!<BR>
+Give me a can of them sweet, yaller peaches,<BR>
+'Cause why? My true-love is daid!"<BR>
+</P>
+
+<P>
+</P>
+
+<P>
+"Oh, give us something cheerful!" laughed Bud, as the cowboy seemed
+about to start on another verse.
+</P>
+
+<P>
+"That's cheerful enough for this occasion," retorted Yellin' Kid.
+"Wait 'till you hear me howl in that tunnel."
+</P>
+
+<P>
+"Don't!" begged Dick with a laugh. "It echoes so you'll bring the roof
+down!"
+</P>
+
+<P>
+There was a hurried inspection of their weapons and supplies, for each
+was equally needed. The inner tubes of several auto tires had been
+provided and tested, and there was a small air pump with which to
+inflate them.
+</P>
+
+<P>
+"All ready?" asked Bud, at length.
+</P>
+
+<P>
+"All ready," answered Old Billee. "But I wish I had a hoss!"
+</P>
+
+<P>
+"Couldn't use one," retorted Snake Purdee. "It'll work off some of the
+fat, if you walk."
+</P>
+
+<P>
+"Hu! Fat!" snorted Old Billee. "I ain't fat!"
+</P>
+
+<P>
+"Forward!" suddenly called Bud.
+</P>
+
+<P>
+Then with waves of their hands, and with the calling of many "good-bye"
+farewells, the expedition disappeared into the black depths of the
+tunnel.
+</P>
+
+<P>
+What would they find? What would be the outcome? Would they ever
+reappear again?
+</P>
+
+<P>
+These were questions which more than one asked himself, but no one
+spoke them aloud.
+</P>
+
+<P>
+"Now," remarked Bud, when they were well within the long stretch of
+blackness, and lanterns had been lighted, "we walked, the other time,
+on the left-hand side of the water course. What say we try the right
+one this time?"
+</P>
+
+<P>
+"Good enough!" decided Old Billee. "We'll be right for once!" he joked.
+</P>
+
+<P>
+"But it really is a good idea," declared Snake Purdee. "There might
+have been something&mdash;some hidden passage on the side you didn't travel,
+boys. You could easily have missed it in the darkness."
+</P>
+
+<P>
+So this was decided on. As a matter of fact in many places it was
+possible for the party to divide and some walk along either side of the
+old stream bed. But this would not be feasible should the water
+suddenly appear again.
+</P>
+
+<P>
+And so the expedition moved slowly along. I say slowly, for that speed
+marked their course. They carried a number of lanterns and these were
+flashed over walls and roof as well as on the bottom, to discover, if
+possible, a branch tunnel, or hole, where the water might travel to,
+and thus be shunted off from the reservoir end. But, for several hours
+nothing occurred, and nothing was discovered. Lunch was eaten in the
+blackness, relieved as it was only by the lanterns, and then the
+expedition started off again.
+</P>
+
+<P>
+"Here's the place where we were when the water came spouting before,"
+said Bud, as they came opposite the ledge on which he and his cousins
+had taken refuge. "I think we ought to spend some time here and&mdash;&mdash;"
+</P>
+
+<P>
+"Hark," suddenly interrupted Nort. "Hear that noise!"
+</P>
+
+<P>
+They all heard it&mdash;a rushing, roaring sound, like the blowing of a
+mighty wind.
+</P>
+
+<P>
+"The water&mdash;the water!" cried Bud. "Look out!"
+</P>
+
+<P>
+They could hear the noise more plainly, now, and as Snake and Billee
+raised their lanterns, the glows flashed on a white, frothy mass
+approaching through the blackness of the tunnel.
+</P>
+
+<P>
+"It's the same as before!" cried Nort. "Get to the ledge! The ledge!"
+</P>
+
+<P>
+He made a leap, running ahead to where he saw a more narrow place that
+would enable him to leap across from the right to the left side of the
+channel.
+</P>
+
+<P>
+And then, while the others hung back for a moment, and Nort thus dashed
+ahead alone, his companions saw him quickly disappear. The wall of
+water suddenly rushed forward, but it never came quite to the place
+where the party of five now stood in nameless terror&mdash;five, for Nort
+had disappeared into the depths of the stream that had so mysteriously
+appeared again out of the blackness.
+</P>
+
+<P>
+From whence it came, and whither it was rushing, not to foam entirely
+over that startled group, none in it could say. But it had engulfed
+Nort&mdash;that they had seen.

+THE FIGURE ON THE ROCK
+</H3>
+
+<P>
+Horror and surprise held the five speechless for a moment. Then, as
+they heard the noise of the rushing water, and saw, by the light of
+their lanterns, that it came almost to them, but suddenly turned to the
+right, they came to their senses.
+</P>
+
+<P>
+"Nort! Nort!" yelled Dick, his voice being flung back at him in echoes
+from the rocky, vaulted roof of the tunnel.
+</P>
+
+<P>
+"What in th' world happened?" asked Old Billee in trembling accents.
+</P>
+
+<P>
+"Nort fell into the stream, and was carried away," answered Bud, his
+voice choking.
+</P>
+
+<P>
+"But why doesn't the water reach us?" asked Snake.
+</P>
+
+<P>
+"That's what we'll have to find out," asserted Bud, bravely. "Come on!"
+</P>
+
+<P>
+"But be careful," cautioned Billee. "Something may happen t' us, an'
+then we can't help Nort! Go easy!"
+</P>
+
+<P>
+He spoke only in time, for the next moment, with an exclamation of
+horror, Bud and Dick, who had forged ahead, recoiled back.
+</P>
+
+<P>
+"Look out!" shouted Bud, and he made such a lurch backward to recover
+his balance that the lantern was flung from his hand. It dropped, as
+they all could see, into the midst of black, swirling waters, white
+foam-capped on top.
+</P>
+
+<P>
+And it was into this stream that Nort had fallen and been carried away,
+and into this stream that Bud and Dick had been nearly precipitated as
+they dashed forward.
+</P>
+
+<P>
+Bud's lantern was extinguished with a hiss as the waters penetrated it
+and covered the wick. It sank from sight, but not before it had, in a
+flash, illuminated the surface of the water.
+</P>
+
+<P>
+"It's a good thing we took the right-hand side," said Billee, as he and
+the others saw what it was that had caused the water to rush almost to
+their feet and then branch off. "I mean it's a good thing, for it may
+help us to solve the mystery. But as for poor Nort&mdash;&mdash;"
+</P>
+
+<P>
+He did not finish, but Dick sent up a despairing cry:
+</P>
+
+<P>
+"Nort! Oh, Nort! Where are you?"
+</P>
+
+<P>
+And only the vaulty echoes answered.
+</P>
+
+<P>
+"What are we going to do?" asked Snake, who seemed unable to suggest
+anything.
+</P>
+
+<P>
+"Everybody come here with their lanterns," directed Bud. "And light
+that spare one, Billee."
+</P>
+
+<P>
+Thus was replaced the one he had dropped in the effort to save himself
+from falling into the same torrent that had engulfed his cousin.
+</P>
+
+<P>
+And in the light of the lanterns, the one Nort had carried being
+forever lost, it seemed they all could see the explanation for the
+apparently mysterious action of the underground stream; or, rather, it
+was an explanation of part of the mystery; for this was only the
+beginning.
+</P>
+
+<P>
+Beyond where they stood, in the direction of Pocut River, there flowed
+through the ancient channel a body of water larger than that which
+usually filled the underground course. This was accounted for, likely,
+by the fact that it had been stopped, or dammed, by some natural or
+artificial means, and had suddenly been released. Thus the channel was
+more fully filled than usual.
+</P>
+
+<P>
+But, as I have said, the water came up to the point where the members
+of the expedition then stood. From there it made a sudden turn to
+their right, as they stood facing the river end of the tunnel. And it
+was this sudden turn&mdash;this shift in the course of the underground
+stream&mdash;which prevented it from engulfing our friends.
+</P>
+
+<P>
+But it had engulfed Nort.
+</P>
+
+<P>
+"I see what happened&mdash;or, at least, part of it," spoke Bud while the
+others listened. "The waters were suddenly turned on again, or turned
+themselves on, and shot this way. Nort heard them and ran down here to
+jump across the stream-bed, which was then dry. But he must have
+fallen over the edge of this traverse ledge, or channel, as I nearly
+did, and down he went!"
+</P>
+
+<P>
+They looked, and agreed that this was very likely how it had taken
+place.
+</P>
+
+<P>
+"But can't we save him?" pleaded Dick. "I'm a good swimmer. Let me
+try to get him! Maybe he's lying down there&mdash;on the bottom!"
+</P>
+
+<P>
+He made as if to take off his coat, but Old Billee grabbed him by the
+arm.
+</P>
+
+<P>
+"You'd only go t' your death, boy!" said the old ranchman hoarsely.
+"It's bad enough&mdash;as it is!"
+</P>
+
+<P>
+"But what happened to Nort?" asked Dick, and there was a sob in his
+voice.
+</P>
+
+<P>
+"He must have been carried away&mdash;down that stream&mdash;wherever it goes,"
+asserted Snake Purdee.
+</P>
+
+<P>
+"That's just the point, where does it go?" Dick asked.
+</P>
+
+<P>
+"Wait a minute," counseled Bud. "Let's see if we can reason this out."
+He paused to give it thought. "The way this stream is running now," he
+resumed, "wouldn't put any water into our reservoir, would it?"
+</P>
+
+<P>
+"No," answered Yellin' Kid, and for once his voice was softened. "Th'
+water is all being shunted down this passage&mdash;where Nort fell."
+</P>
+
+<P>
+"But," resumed Bud, "this passage has always been here. We didn't see
+it before, as we walked on the other side of the main channel. Then if
+this side channel has always been here, and we managed to get water
+through our pipe when it was here, it stands to reason that it must
+fill in time, enabling the water to run along here," and he indicated
+the regular channel that extended back of them out toward Flume Valley.
+</P>
+
+<P>
+"That's so!" cried Old Billee. "There's an end, or a bottom, t' this
+channel somewhere, and poor Nort can't be carried all the way through
+th' earth."
+</P>
+
+<P>
+"But&mdash;but," faltered Dick. "It may be too late to save him when this
+side passage fills up."
+</P>
+
+<P>
+"What I was going to propose," went on Bud, "is that we see if we can't
+follow along this newly-discovered side passage, as we have been
+following the main bed of the underground river."
+</P>
+
+<P>
+He paused to let his companions visualize this suggestion.
+</P>
+
+<P>
+"Do you think that would be safe?" asked Old Billee. "I mean," he
+added quickly, "will that be th' safest way t' try an' save Nort? I
+won't back down on anything&mdash;I guess you know that&mdash;but I was just
+wondering if there was some other way."
+</P>
+
+<P>
+"There might be," said Bud. "We could go along on the left side of the
+stream, and see if there is a crossing place farther on. We saw some
+narrow places when we were here before, but it's a question how much
+water they'd have in them now."
+</P>
+
+<P>
+"Oh, but can't we do something?" cried Dick, now almost sobbing, though
+he was making a brave effort to conquer himself. "Oh, Nort! Nort!
+Where are you?" he cried frenziedly.
+</P>
+
+<P>
+But again only the echoes answered.
+</P>
+
+<P>
+"Come on!" cried Old Billee suddenly. "We'll try this way. We've got
+t' do something!"
+</P>
+
+<P>
+"Leave our packs here," suggested Yellin' Kid, and again his voice was
+low, as if in deference to Dick's feelings. "We can put 'em up on that
+ledge," he added, indicating a small one on their side of the
+underground stream. "The water doesn't appear to have been up there in
+years. If we leave our things here we'll be better able to help
+Nort&mdash;if we find him," he added in a voice so low that only Old Billee
+heard.
+</P>
+
+<P>
+"Take our lanterns," suggested Snake Purdee.
+</P>
+
+<P>
+"And ropes," went on Bud. "We may need 'em!"
+</P>
+
+<P>
+Accordingly the food and other supplies, which the searchers after the
+secret of the underground water course had brought with them, were put
+up on the ledge, and then they started down the black passage through
+which the stream appeared to have branched, carrying Nort with it.
+There was room but for one to walk at a time on this "bank," as it
+might be called, of the hidden stream, and they had to proceed in
+single file.
+</P>
+
+<P>
+"I'd like to see a map of this place, so we'd know where we were
+going," spoke Old Billee, as he swung his lantern from side to side in
+an endeavor to disclose the hidden secrets of the place.
+</P>
+
+<P>
+"I have an idea that the underground stream is shaped like the letter
+T," spoke Bud. "The top, or cross stem, is the part that extends from
+the river to our reservoir. We are now walking along the upright
+piece."
+</P>
+
+<P>
+"But if the main part of the T is also a stream, and the water is
+running down that, as it is, instead of along the main stem, it becomes
+for the time being a letter L, doesn't it?" asked Snake.
+</P>
+
+<P>
+"Yes," assented Bud. "And as long as the water turns at right angles,
+as it does at the place where Nort fell in, and as long as the water
+runs along this same side passage, we don't get any at Flume Valley.
+The letter T is in our favor, and L is against us."
+</P>
+
+<P>
+"But we didn't see anything like this when we were here before,"
+remarked Dick.
+</P>
+
+<P>
+"Because we weren't on this side," Bud answered. "And I have an idea
+that, in time, this second passage finally fills with water completely,
+and when it does the stream again flows along the cross stem of the T
+and we get it."
+</P>
+
+<P>
+"Mebby you're right," Old Billee agreed. "But this isn't finding Nort."
+</P>
+
+<P>
+"Will we&mdash;will we ever find him?" faltered Dick.
+</P>
+
+<P>
+"Sure!" declared Bud, as heartily as he could.
+</P>
+
+<P>
+But as they progressed in the darkness, stopping now and then to look
+about by means of the light, calling again and again, and as no reply
+came, even the heart of the stoutest of them sank in despair.
+</P>
+
+<P>
+All they could see was black, rushing water, flowing in a channel it
+appeared to have cut, after countless years, in the solid rock. There
+was a narrow footpath, so to speak, on either side of this stream, and
+it was along this the searchers were walking.
+</P>
+
+<P>
+Suddenly Bud, who was in the lead, uttered a strange cry.
+</P>
+
+<P>
+"What's the matter?" exclaimed Dick. "Do you see him?"
+</P>
+
+<P>
+"No! But look!" went on Bud. "We have come out into a regular
+underground cave! It's as big as a house!"
+</P>
+
+<P>
+He flashed his lantern around in a circle, and as the others came up
+and stood beside him, at a spot where the passageway beside the stream
+widened, they saw that they had emerged into a great vault.
+</P>
+
+<P>
+And as they stood there, awed and marveling, there came to them, above
+the rustle and whispering of the rushing waters, the sound of a human
+voice&mdash;it was as though someone, sorely hurt, had moaned.
+</P>
+
+<P>
+"Listen!" cried Dick.
+</P>
+
+<P>
+"Hold up your lanterns!" commanded Bud sharply.
+</P>
+
+<P>
+As they raised them, throwing the combined light farther out across the
+stream that had widened into a pool in the vault, Dick uttered a cry.
+</P>
+
+<P>
+"I see him! I see Nort!" yelled Dick. "There, on the rock!"
+</P>
+
+<P>
+And he pointed to the huddled figure of some one on a great rock in the
+middle of the pool of black water, which seemed, a short distance from
+the inflowing stream, to be as quiet as a lake. And, as they watched
+in the gleam of the lights, the figure on the rock moved slightly.
+</P>
+
+<P>
+"Nort! Nort!" cried Dick, and his voice was flung back in deafening
+echoes from the vaulted roof.

+THE WATER GATE
+</H3>
+
+<P>
+While they eagerly watched, the solitary figure on the big rock in the
+midst of that sinister pool again moved slightly, and as it became
+partly erect it was seen to be Nort Shannon.
+</P>
+
+<P>
+"We've found him! We've found him!" joyfully cried Dick.
+</P>
+
+<P>
+"An' alive, too, if I'm any judge," added Billee.
+</P>
+
+<P>
+Dick was stripping off his coat, when Bud placed a hand on his shoulder.
+</P>
+
+<P>
+"Wait a minute," advised the western lad.
+</P>
+
+<P>
+"But I'm going to get him!" objected the brother. "I'm going to save
+Nort!"
+</P>
+
+<P>
+"Maybe it isn't safe, and we may be able to save him in another way,"
+suggested Bud. "I say, Nort," he called. "Are you hurt?"
+</P>
+
+<P>
+How eagerly they all waited for the answer, after the echo of Bud's
+voice had ceased reverberating in the big cave!
+</P>
+
+<P>
+"Yes&mdash;I&mdash;I'm all right," came the faint answer across the silent pool.
+"I don't know exactly how I got here. Something hit me on the
+head&mdash;after I fell&mdash;fell in. I reckon I must have floated near this
+rock and&mdash;and just naturally grabbed hold and&mdash;pulled myself&mdash;up!"
+</P>
+
+<P>
+"That's enough! Take it easy now!" called Bud. "We're coming over to
+get you!"
+</P>
+
+<P>
+"Sure you're not hurt?" asked Dick, his voice trembling.
+</P>
+
+<P>
+"Nothing more than a bump on the head," answered Nort, his own tones
+stronger now. "Not half as bad as I've gotten at football," and he
+laughed a little&mdash;the most joyful sound any of them had heard since the
+sweeping away of the boy rancher.
+</P>
+
+<P>
+"Well, now we've found him, the next thing is to get him over here,"
+spoke Bud. "Two of us had better swim out there. This water looks to
+be all right," and he stooped down and tested it with his hand. "As
+warm as the river," he added.
+</P>
+
+<P>
+"I'm going to swim out!" declared Dick, and this time, as he began to
+"peel," no one stopped him.
+</P>
+
+<P>
+"I'll go with you," said Bud. "We'll tie the ropes around our waists
+and they can hold them here on shore. It will be better than taking a
+risk, using the old tires," he added, "and, while there isn't any
+current in the pool now, no telling what may happen."
+</P>
+
+<P>
+"Sure you want the ropes," said Old Billee. "But you'd better take a
+tire for Nort," and they did.
+</P>
+
+<P>
+"Hold hard, Nort!" called Dick, as he and Bud took off their clothes in
+preparation for the swim. "We're coming!"
+</P>
+
+<P>
+"I'll hold hard all right," came the answer back across the pool. "And
+there's something hard here to hold on to, all right."
+</P>
+
+<P>
+They did not then realize his meaning, but they understood, later, when
+they made a most amazing discovery.
+</P>
+
+<P>
+In a few minutes Dick and Bud were in the water, lariats held by those
+on "shore" tied around their waists; and the two boy ranchers were
+swimming toward the big rock in the middle of the pool. Lanterns at
+the edge of this strange underground body of water gave sufficient
+light to enable the swimmers, and the others, to see Nort now standing
+on the great boulder which emerged from the midst of the black water.
+</P>
+
+<P>
+It was the plan of Bud and Dick to help Nort to swim back to where the
+others stood, they supporting him on either side. For though Nort was
+a better swimmer than his brother, in his weakened condition, hit on
+the head as he had said, he might suddenly collapse.
+</P>
+
+<P>
+So also might Bud and Dick, or there might suddenly appear a swift
+current in the now quiet pool&mdash;that is, quiet beyond where the stream
+flowed in&mdash;and in that latter event the lariats would serve to pull
+them all to safety.
+</P>
+
+<P>
+"Gee! I thought you were a goner!" gasped Dick, as he climbed out and
+clasped his brother by the hand.
+</P>
+
+<P>
+"I would have been, only that I floated near this rock, and managed,
+half unconscious as I was, to grab hold of a projection and pull myself
+up," Nort answered. "That water came up so fast it scared me, and I
+slipped right into it."
+</P>
+
+<P>
+"We saw you," said Bud, sitting down on the rock to get his wind, so he
+might be at his best in helping Nort on the return journey.
+</P>
+
+<P>
+"It was&mdash;awful!" spoke Dick simply, and then he made no further
+reference to his mental agony.
+</P>
+
+<P>
+"Well, are you ready to go back?" asked Bud, after a pause, in which
+interim they had called to those across the pool that the lost lad was
+all right.
+</P>
+
+<P>
+"I'm ready, yes," was Nort's answer. "But I'd sort of like to see what
+this hard lever-like object is."
+</P>
+
+<P>
+"Oh, yes," spoke Dick. "You said you had something hard to hold to.
+Let's have a look&mdash;if we only had a light," he added, for it was quite
+dark on the great rock in the midst of the black pool. The light of
+the lanterns did not brightly penetrate that far.
+</P>
+
+<P>
+"I have some matches, in a waterproof case, if I didn't lose it out of
+my pocket," said Nort, feeling in his soaking trousers. "Here they
+are," he went on a moment later. And as his hands were drier than
+those of Bud or Dick, Nort opened the box and managed, after one or two
+failures, to strike a light.
+</P>
+
+<P>
+As the little taper flared up the three boys on the rock saw, standing
+upright about in the centre of the large boulder a great handle, or
+lever, of copper. The metal gleamed dully red in the flickering light.
+</P>
+
+<P>
+"What is it?" asked Bud, as Nort struck another light.
+</P>
+
+<P>
+"I don't know," was the answer from Nort. "I discovered it when I was
+crawling about and feeling around. I thought, if worst came to worst,
+I could hold to this if the waters rose."
+</P>
+
+<P>
+"They seem to be as high as they're going to get," said Bud. "But this
+sure is queer! Hold your match closer, Nort."
+</P>
+
+<P>
+Another of the tapers was lighted, and across the pool came the voice
+of Snake Purdee, asking what was going on.
+</P>
+
+<P>
+"There's some sort of a handle, or lever, here," answered Bud, as he
+examined it more closely. "It moves, too," he added as he laid his
+hands on it and pulled it toward him.
+</P>
+
+<P>
+"Look out!" cautioned Dick, but it was too late.
+</P>
+
+<P>
+Bud had pulled the copper lever toward him, and, in spite of its size
+and weight, it moved easily in what appeared to be a slot in the rock.
+It clicked slightly, as though connected with hidden mechanism.
+</P>
+
+<P>
+Then, with a suddenness that was startling, a low but ever-increasing
+roar seemed to fill the cavern in which was the black pool. The roar
+grew louder and louder, and the very rock beneath their feet seemed to
+tremble.
+</P>
+
+<P>
+"What have you done?" gasped Dick.
+</P>
+
+<P>
+"Search me!" answered Bud in such queer tones that Nort laughed.
+</P>
+
+<P>
+And then a strange thing happened. As Nort struck another match he and
+the boys on the rock could see the water all about them beginning to
+recede. Slowly it flowed at first and then, with a rush, it began
+running out of the place as fast as it had run in.
+</P>
+
+<P>
+"What's up over there?" called the voice of Old Billee from "shore," so
+to speak. "What you fellers doin' with th' water?"
+</P>
+
+<P>
+"I just pulled that lever," sang out Bud.
+</P>
+
+<P>
+"Then you've done the trick!" said the old cowboy. "You must have
+opened some gate, and the water's running away. Better swim over here
+while you have the chance. When the water comes back that rock may be
+covered!"
+</P>
+
+<P>
+But another strange part of their mysterious adventures was that they
+did not have to swim back. For the water receded so rapidly that, in a
+little while, it was possible to wade from the rock to the stone edge
+of the pool where the other members of the party stood. And wade back
+to their friends Bud, Dick and Nort did.
+</P>
+
+<P>
+"Oh, boy! But we're glad to see you!" cried Old Billee, as he caught
+Nort by the hand.
+</P>
+
+<P>
+"You let out a mouthful that time!" declared Yellin' Kid, and his voice
+nearly split their ear drums, so magnified was it by the echoing,
+vaulted roof of the cavern.
+</P>
+
+<P>
+"But what all happened?" asked Snake Purdee. "Is there some old
+Mexican grain mill under here that has a water-wheel, sluices and
+gates?"
+</P>
+
+<P>
+"I give it up," answered Bud. "All I know is that I pulled that copper
+lever&mdash;and it's copper so it won't rust off, I reckon&mdash;and the water
+began to rush out as fast as it must have come in here."
+</P>
+
+<P>
+"It is mighty queer," agreed Old Billee. "Let's go take a look," and
+he started to walk across the intervening space between shore and the
+great rock&mdash;a space in which only a few puddles of water now remained.
+</P>
+
+<P>
+"Will it be safe?" asked Bud, who had begun to dress, an example
+followed by Dick.
+</P>
+
+<P>
+"Why not?" asked Old Billee. "The water can't rise any higher than it
+was when you fellows were on the rock. An', according to your tell,
+there's room enough for us all t' stand there."
+</P>
+
+<P>
+"Yes, it's big enough," agreed Bud. "But suppose we all get there, and
+the water begins to come back?"
+</P>
+
+<P>
+"We'll turn it loose again with th' lever," answered the old cow
+puncher. "But I reckon it can't fill up this pool again until that
+lever is shifted hack where it was before you yanked it."
+</P>
+
+<P>
+"Maybe not," admitted Bud. "Well, let's take a chance. If worst comes
+to worst we can swim back, and I'd like to solve this mystery. I feel
+that we're getting at it now!"
+</P>
+
+<P>
+"That's right," said Nort, who was feeling stronger every moment.
+"When I fell in, and was carried away," he said, "I had a wild notion
+that this might lead to the discovery of something. I managed to keep
+my head out of water as I was swept along, until I got a knock on the
+noodle, and that put me partly to sleep. That may have been a good
+thing, too, for they say a partly unconscious person doesn't breathe
+much, and that's why I didn't swallow any water to speak of.
+</P>
+
+<P>
+"I was dazed when I must have been swept, or floated, past that rock
+but I came to in time to save myself. Gosh! but I was glad to hear you
+yell though, Dick!" he said.
+</P>
+
+<P>
+"Well, let's get over there an' start pryin' out this secret,"
+suggested Old Billee. "This is gettin' mighty interestin'!"
+</P>
+
+<P>
+It seemed reasonable to suppose that the water would rise to no greater
+height than it had when the searchers had discovered Nort on the rock.
+And as this boulder was well out of water, and large enough for them
+all to stand on, they would run no risk, even if the flood should start
+to return when they were in the middle of the pool, which, however, was
+a pool no longer, but merely a wet reservoir, so to speak.
+</P>
+
+<P>
+"But I don't believe the water will flow back here until you shift that
+lever again, Bud," declared the old ranchman. "And I'm going to have a
+try at it!"
+</P>
+
+<P>
+"Isn't it takin' a chance?" asked Snake.
+</P>
+
+<P>
+"You got t' take chances in this world!" declared Old Billee.
+</P>
+
+<P>
+"Well, let's go!" suggested Bud.
+</P>
+
+<P>
+"I think I'll stay here," spoke Nort. "I don't feel quite up to
+walking over those rocks. And you may need some one on this side who
+can throw a rope," he added, as he looked at the lariats.
+</P>
+
+<P>
+"All right," assented Bud. "You stay here, Nort."
+</P>
+
+<P>
+They left him on the shore, as I call the rocky edge of the pool, with
+a lantern, and, taking other lanterns with them, the little party set
+out. It took them only about three minutes to walk across to the great
+rock, which stood upright in the middle of the cavern floor.
+</P>
+
+<P>
+Rising up in almost the very centre was the heavy, copper lever. By
+the light of the lanterns it was examined, and seen to extend down
+through the rock, whither no one knew.
+</P>
+
+<P>
+"It works a water gate all right," declared Old Billee. "Let's pull it
+back to where you found it, Bud, and see what happens."
+</P>
+
+<P>
+It was with some feelings of apprehension that the others watched as
+Old Billee reached for the copper lever and pulled it toward him, It
+operated as easily as it had for Bud.
+</P>
+
+<P>
+And almost as quickly as had taken place on the other occasion, there
+was that roaring, rumbling sound, a noise as of the blowing of a great
+wind, and then the waters began to rush back into the pool.
+</P>
+
+<P>
+"Here they come!" yelled Dick, as he stood beside Bud on the rock.
+</P>
+
+<P>
+Truly the waters were returning as the hidden gate was closed when
+Billee pulled the lever.
+</P>
+
+<P>
+Would they go down again?
+</P>
+
+<P>
+That was what each one asked himself.

+THE CONSPIRATORS
+</H3>
+
+<P>
+Rapidly rushing, foaming, bubbling and boiling, the waters rushed into
+the mysterious cavern, until they again filled the pool across which
+Bud and Dick had swam to the rescue of Nort on the rock. Now the
+situation was reversed. It was Nort who was on the mainland, or shore,
+so to speak, and the others who were on the rock.
+</P>
+
+<P>
+But it was one of their own choosing, in an endeavor to solve the
+mystery, though as Bud and his companions watched the waters creeping
+higher and higher up the surface of the rock on which they stood, their
+hearts were not altogether easy.
+</P>
+
+<P>
+"Suppose it covers the rock?" asked Dick.
+</P>
+
+<P>
+"Then we'll have to swim back where Nort is," Bud answered.
+</P>
+
+<P>
+"Shucks! You won't have to do nothin' of the sort!" declared Old
+Billee stoutly. "She won't come up any farther than it did before!"
+</P>
+
+<P>
+And he was right. When the water around the rock lapped the erosion
+mark, which had been worn in the hard stone by centuries of the flow of
+the fluid, the flood ceased. The roaring, bubbling and seething, like
+that which takes place in a canal lock, came to an end, and the water
+of the pool became quiet.
+</P>
+
+<P>
+"There! What'd I tell you?" cried Old Billee. "I closed th' water
+gate, that Bud opened to let th' water out, an' she come back. Now all
+we have t' do, so we can walk back, is t' yank this lever again."
+</P>
+
+<P>
+"Does it only work two ways?" asked Yellin' Kid, his voice again
+softened, as the mystery of the place seemed to cast a shadow over him
+and the others.
+</P>
+
+<P>
+"Seems to," Bud answered, holding his lantern down close to where the
+copper handle entered the rock.
+</P>
+
+<P>
+There appeared to be a slot cut in the hard stone&mdash;a slot about three
+inches wide, and a foot long, in which the copper lever could be moved
+backward and forward, but not from side to side.
+</P>
+
+<P>
+"Let's try the other way, now," suggested Dick.
+</P>
+
+<P>
+Once again Old Billee pulled on the copper shaft, which, as they could
+see by the light of all their lanterns combined, seemed to have been
+rudely hammered out, for it bore the rough marks of a primitive forge.
+</P>
+
+<P>
+And no sooner had the lever been pulled to its limit in the slot than
+there sounded again the rushing, roaring tumult of noises, and, after a
+little, the water began receding once more.
+</P>
+
+<P>
+"We've discovered the secret!" cried Dick.
+</P>
+
+<P>
+"No, only part of it," said Bud. "We've got to find where the water
+goes, and if pulling this lever sends it into our reservoir. That's
+the main thing to discover."
+</P>
+
+<P>
+"But we're on the track of part of it," went on Dick. "I wonder who
+built this secret water gate, and the lever that operates it?"
+</P>
+
+<P>
+"It may be part of the work of the ancient Mexicans, the old Indians or
+the Aztecs, who inhabited this land ages ago," said Bud. "Copper will
+last almost forever, you know, even in water, as it doesn't rust. And
+you've read how the ancient Aztecs used to build great vaults under the
+mountain, and arrange to flood them to keep their gold away from the
+Spaniards."
+</P>
+
+<P>
+"Yes, I've read of that," admitted Dick.
+</P>
+
+<P>
+"Say, where can you get a book like that?" demanded Old Billee.
+</P>
+
+<P>
+"I've got one at the camp," Bud answered. "I'll let you take it. Of
+course my theory may be all wrong," he went on. "But I begin to
+believe we've stumbled on some ancient Aztec water system."
+</P>
+
+<P>
+"You don't mean to say those old Mexicans, for that's what the Aztecs
+were, are still hanging around in this cave, turning your water on and
+off, do you?" demanded Dick.
+</P>
+
+<P>
+"No, it's some one more modern who's making trouble for us," Bud
+declared. "But we're on the track of a big discovery, I believe.
+Look, the water is almost gone!"
+</P>
+
+<P>
+This was true. The pool was emptying itself as it had done before,
+and, in a short time they could walk back to where Nort awaited them.
+</P>
+
+<P>
+"What's the next thing to do?" asked Dick.
+</P>
+
+<P>
+"Get back where we left our grub and feed our faces," suggested Snake
+Purdee.
+</P>
+
+<P>
+"Yes, I think that will be best," Bud said. "Then we can talk over the
+next move. I begin to feel hungry."
+</P>
+
+<P>
+"I hope we won't be disappointed," remarked Yellin' Kid and his vocal
+powers seemed to be on the mend, for he called loudly.
+</P>
+
+<P>
+"Disappointed? How?" asked Old Billee.
+</P>
+
+<P>
+"I mean I hope we find our grub where we left it," Kid explained.
+</P>
+
+<P>
+"Why wouldn't it be there?" Old Billee wanted to know. "Do you think
+them Hatchet-texts have sneaked in and took it?"
+</P>
+
+<P>
+"You mean Aztecs?" laughed Yellin' Kid. "No, I wasn't referrin' to
+them. I mean I hope our monkeyin' with that copper handle didn't send
+the flood over the place where we left our things."
+</P>
+
+<P>
+"I never thought of that," said Bud. "By Zip Foster! I hope nothing
+like that <I>has</I> happened!"
+</P>
+
+<P>
+With anxious hearts they hastened back to the place where Nort had been
+swept away. They had left the strange lever set to drain the pool, and
+what state of affairs they would find on returning to their point of
+digression no one could say.
+</P>
+
+<P>
+"Maybe we'll find the water running on into Flume Valley," suggested
+Nort, who seemed to be almost himself again, except for a feeling of
+weakness.
+</P>
+
+<P>
+"I hope so," spoke Bud.
+</P>
+
+<P>
+But this was not the case. On reaching the place where the tunnel
+branched, they found no water there at all. None was running in the
+main channel, and none was turning off down the "stem of the T," to use
+the illustration I first employed.
+</P>
+
+<P>
+"Keeps on being strange, doesn't it!" said Bud.
+</P>
+
+<P>
+They all agreed with him.
+</P>
+
+<P>
+"What's the next move?" asked Dick, as they gazed about, finding their
+food and supplies safe, and no water, to mention, anywhere about.
+</P>
+
+<P>
+"Let's grub!" suggested Snake.
+</P>
+
+<P>
+"And make a fire and heat the coffee," urged Bud. "I don't believe the
+smoke will do any harm, and there's plenty of dry driftwood in the
+higher places, and on little ledges."
+</P>
+
+<P>
+"Some hot coffee would go down mighty well!" remarked Nort.
+</P>
+
+<P>
+"Then you're going to have it!" asserted his cousin. They had brought
+some of the cold beverage along in tin flasks, and these were soon
+heating over a little blaze that was kindled along the bank of the
+underground stream that was again dry.
+</P>
+
+<P>
+The food and hot drink put new hearts into all of them, especially
+Nort, and when appetites were appeased they gathered about the
+cheerful, if small, blaze, which gave off scarcely any smoke, and held
+a discussion.
+</P>
+
+<P>
+"What I think we had better do," said Bud, "is to travel on until we
+come to the place&mdash;if such a place there is&mdash;where this stream again
+shunts off to the side. For I'm sure there is such a place if we find
+that the water is running into the tunnel from the river."
+</P>
+
+<P>
+"We can't be sure of that, though," Old Billee said.
+</P>
+
+<P>
+"No, but we can find out when we get to the other end of the tunnel,"
+declared Bud. "My idea is&mdash;though, of course, I might be wrong&mdash;that
+there are two side passages, so to speak. Sometimes the water branches
+off the main channel and fills the pool where we found Nort on the
+rock. Then it may flow down another channel, farther on, but nearer to
+the river end of the tunnel."
+</P>
+
+<P>
+"But if the water came along the main channel, until it got here, and
+then filled the pool to the limit, as was evidently the case,"
+suggested Nort, "why wouldn't the water then back up and go on to our
+reservoir&mdash;and it didn't do that."
+</P>
+
+<P>
+"There may be some outlet from that pool and cavern where we were,"
+said Bud.
+</P>
+
+<P>
+They considered this for a moment, and agreed that he might be right.
+</P>
+
+<P>
+"Then what we've got to look for," went on Bud, "is another side
+passage where the water is shunted off, that is, providing it is not
+cut off at the river pipe. And if there is such a passage it must be
+on the right-hand side of the stream, as was the one where Nort fell
+in. For we went all along the left-hand bank the other time, and
+didn't discover anything."
+</P>
+
+<P>
+"And suppose we find the second branch stream now&mdash;what will we do?"
+asked Snake.
+</P>
+
+<P>
+"Two of us will come back and work the lever, while the others stay at
+the second stream to see what happens," was Bud's answer. "Come on;
+let's go!"
+</P>
+
+<P>
+They put out the fire, packed their belongings, and, making sure that
+Nort was able to travel, they set out again. Nort's garments were
+soaking wet, or, rather, they had been, but there was a current of warm
+air in the tunnel, and soon he began to dry out, for which he was very
+thankful.
+</P>
+
+<P>
+They found the second branching stream sooner than they expected. It
+was less than a quarter of a mile from the first, or the one into which
+Nort had fallen, and it was almost of exactly the same character.
+</P>
+
+<P>
+"Look out! Here it is!" cried Bud who saw it first, his lantern
+gleaming on the swiftly-rushing water. "Go easy!"
+</P>
+
+<P>
+And "easy" they went, reaching the edge of the ledge below which flowed
+the mysterious, powerful current.
+</P>
+
+<P>
+"We can go along here, just as we did before. Here's another branch
+tunnel!" announced Dick, holding up his lantern, and showing a wide,
+high passage, the bottom and middle part of which was occupied by the
+stream.
+</P>
+
+<P>
+"I wonder how many of them there are?" remarked Nort as he and the
+others turned into the black opening, which seemed to slope as though
+descending a hill. This gave greater force to this stream of water.
+</P>
+
+<P>
+"And I wonder if it also runs into a cavern, with a rock and a copper
+lever in the middle!" voiced Dick.
+</P>
+
+<P>
+"Hope we find out soon," spoke Bud. "This is getting more and more
+queer all the while."
+</P>
+
+<P>
+They tramped on in the blackness that was relieved only by their
+swaying lanterns. They walked beside the strange, underground stream,
+and they had progressed farther than along the other branching body of
+water when Old Billee, who was ahead just then, suddenly halted and
+uttered a warning.
+</P>
+
+<P>
+"Listen!"
+</P>
+
+<P>
+"What is it?" asked Yellin' Kid, in his usual tones, but Billee reached
+back and gave him such a dig in the ribs that Kid subsided with a grunt.
+</P>
+
+<P>
+"I hear talkin'!" whispered Billee. "Voices! There's some one else in
+this place than us! Listen!"
+</P>
+
+<P>
+They stopped and strained their sense of hearing. And then, above the
+slithering murmur of the water, they all distinctly heard a voice say:
+</P>
+
+<P>
+"I think we've fixed 'em this time! They won't steal any more water
+from Pocut River!"
+</P>
+
+<P>
+The boy ranchers looked at each other.
+</P>
+
+<P>
+"Del Pinzo!" whispered Nort.
+</P>
+
+<P>
+"As sure as Zip Foster ever ate ham and eggs!" agreed Bud.
+</P>
+
+<P>
+"Hush!" begged Old Billee.
+</P>
+
+<P>
+And as they became quiet again they heard another voice say:
+</P>
+
+<P>
+"I guess it's all up with 'em now. We might as well light out and
+touch off the fuse!"
+</P>
+
+<P>
+"Whew!" softly whistled Bud.
+</P>
+
+<P>
+Together the party of searchers moved softly forward. Suddenly the
+passage along the bank of the mysterious stream turned sharply, almost
+at a right angle.
+</P>
+
+<P>
+And there, in what appeared to be a small cave, excavation or cavern,
+high in the upper wall was disclosed a roughly circular opening, like a
+window or port hole. Through this port hole a light showed, and
+outlined in the light were several rough-appearing men, leaning
+together over what might have been a table.
+</P>
+
+<P>
+"Del Pinzo!" murmured Dick.
+</P>
+
+<P>
+"Conspirators!" exclaimed Bud. "They're the ones that's been turning
+this water on and off! We're on the track of the mystery now!"
+</P>
+
+<P>
+Whether he spoke loudly enough to be heard, or whether some other sound
+made by the searchers alarmed the men in the upper niche, was not
+disclosed just then.
+</P>
+
+<P>
+But the light suddenly went out, and confused sounds followed.
+</P>
+
+<P>
+And chief among these sounds was the rushing, roaring noise, the
+blowing as of a mighty wind, and the water near the boy ranchers and
+their companions was strangely agitated.

+CHAPTER XXIV

+A POWERFUL STREAM
+</H3>
+
+<P>
+"Better look out!" came the high-pitched voice of Yellin' Kid.
+</P>
+
+<P>
+"There may be a flood here!" added Old Billee.
+</P>
+
+<P>
+"Can't we get those rascals?" cried Snake Purdee. "I'd 'a' had th'
+drop on 'em in another second if they hadn't doused that glim!"
+</P>
+
+<P>
+As he spoke they could all hear the rush of iron-nailed shoes when the
+wearers of them scrambled over hard rocks in their effort to escape.
+</P>
+
+<P>
+Mingled with that sound was the strange one of rushing water.
+Realizing that danger might come to them more through the agency of the
+strangely-acting underground stream than from the actions of the
+conspirators, Bud and Nort flashed their lanterns on the water-course
+behind them and around the bend which they had turned to behold the
+strange scene.
+</P>
+
+<P>
+"It's going down!" cried Bud, for there was no longer any advantage in
+concealment or silence, as long as Del Pinzo and the others had fled.
+"It's receding!"
+</P>
+
+<P>
+"Just as the other did!" added Dick. "They must have opened a gate
+here and let the water out!"
+</P>
+
+<P>
+"They've done something!" cried Bud, "and we've got to find out what it
+is."
+</P>
+
+<P>
+"Did you hear that about a fuse?" demanded Snake. "Maybe they're going
+to blow the place up!"
+</P>
+
+<P>
+"If they do, and the tunnel caves in, good-bye to my water!" said Bud.
+</P>
+
+<P>
+"Yes, and good-night to <I>us</I>!" grimly added Old Billee.
+</P>
+
+<P>
+"Come on!" cried Yellin' Kid. "Let's see what's up there in that hole
+in the wall, anyhow!"
+</P>
+
+<P>
+"And have your guns ready!" warned Snake Purdee.
+</P>
+
+<P>
+However, as it developed, the weapons were not needed. When the boy
+ranchers and their friends managed to scramble up the rocky way, above
+and to the right of the second hidden, branching stream, and found
+themselves in what was virtually a little natural recess hollowed out
+of the rocky wall, they saw that it was deserted.
+</P>
+
+<P>
+But there were plain evidences of the fact that the men they had seen
+had fled in a hurry, as, indeed, they had practically witnessed.
+Playing cards, cigarettes, tobacco and bottles were scattered on a rude
+wooden table, and there were several candle-ends stuck in the necks of
+flasks. The smell of the extinguished candles was heavy on the air.
+</P>
+
+<P>
+"But where did they go?" asked Bud, when a hasty glance around the
+rocky room disclosed no occupants.
+</P>
+
+<P>
+"What's that?" asked Dick, pointing to what seemed to be a hole in the
+floor at one corner.
+</P>
+
+<P>
+"It's a passage!" cried Billee, holding his lantern above it. "An' big
+enough, even for me! I'm going down!"
+</P>
+
+<P>
+"Will it be safe?" asked Nort. "It may lead into the stream, or to
+where they have planted a mine&mdash;they spoke of a fuse&mdash;&mdash;"
+</P>
+
+<P>
+"You've got to take chances in times like these!" declared Old Billee.
+"I guess if they went down it will suit us."
+</P>
+
+<P>
+"Unless they can close it up, or turn water in," suggested Snake,
+dubiously.
+</P>
+
+<P>
+"Git out! I'm going down!" stoutly declared the rather fleshy veteran
+cow puncher, and when he let himself down the hole the others followed.
+</P>
+
+<P>
+There was a natural stairway, or what served the same purpose, leading
+down out of the stone room where the conspirators had been evidently
+plotting so far underground. The passage went down, at first, like a
+flight of steep, cellar stairs. Then it straightened out, and, after
+twists and turns, led upward.
+</P>
+
+<P>
+"Where are we going?" asked Nort.
+</P>
+
+<P>
+"Nobody knows!" grimly answered Bud. "But it's safe so far!"
+</P>
+
+<P>
+"And we're right on their trail!" added Snake.
+</P>
+
+<P>
+"How do you know?" asked Billee.
+</P>
+
+<P>
+For answer Snake paused and pointed to a smouldering cigarette stub on
+the rocky floor of the passage that had led out of the conspirators'
+niche.
+</P>
+
+<P>
+"That wasn't dropped many minutes ago," declared the cowboy. "They
+came along here."
+</P>
+
+<P>
+This was evident, but it was also evident that Del Pinzo and his
+conspirators were sufficiently in advance to escape. For, with another
+sudden turn, the passage led to another natural, rocky stairway, and
+when this had been mounted the boy ranchers found themselves again in
+the main tunnel.
+</P>
+
+<P>
+"What's this?" cried Bud, when it was evident that they had come back
+to the place whence they had started, but farther on, and nearer to the
+river end of the tunnel. "This is a regular maze!"
+</P>
+
+<P>
+"But where is Del Pinzo?" asked Dick.
+</P>
+
+<P>
+"Out there, I fancy," and Nort pointed to where the main tunnel
+extended under the mountain and beyond, to the dam in Pocut River.
+"They've gotten away!"
+</P>
+
+<P>
+"And about time, too!" added Snake, "or they'd be trapped as we may be!"
+</P>
+
+<P>
+"Trapped!" cried Old Billee. "What do you mean?"
+</P>
+
+<P>
+"I mean there's a mine set here, somewhere! Don't you smell powder
+smoke?"
+</P>
+
+<P>
+A sharp, acrid odor, once smelled never forgotten, came to the nostrils
+of all as they stood there in the tunnel, while the stream flowed
+beside them. Whatever the conspirators had done, they had, evidently,
+not shut off all the water.
+</P>
+
+<P>
+"There it is!" cried Dick, and he pointed to where, in the light of the
+lanterns, there could be seen, slowly ascending, a thin wisp of smoke.
+</P>
+
+<P>
+"Look out!" yelled Old Billee as Dick dashed forward. "It may explode!"
+</P>
+
+<P>
+Then, as Dick rushed up with his lantern, they saw trailing over the
+floor of the tunnel, and on the same side of the stream as themselves,
+a thin white fuse, like a sinister snake. It was this burning fuse
+which caused the smoke.
+</P>
+
+<P>
+It was the work of but an instant for Dick to step on it, and
+extinguish the smouldering spark, while it yet had some distance to
+travel before the fuse lost itself in a mass of rocks.
+</P>
+
+<P>
+"Whew! That was a close call!" exclaimed. Bud, when the fuse was
+entirely out.
+</P>
+
+<P>
+"Let's see where it leads to," suggested Snake.
+</P>
+
+<P>
+They followed it up, and discovered a hidden mine of explosives, tamped
+down into a hole that had been drilled in the rocky floor. Iron bars,
+hammers and other mining implements showed that the perpetrators of the
+dastardly deed had evidently fled in a hurry.
+</P>
+
+<P>
+"They were going to blow up the tunnel!" cried Nort.
+</P>
+
+<P>
+"And when that collapsed it would mean the end of Flume Valley," spoke
+Bud soberly.
+</P>
+
+<P>
+"We never could have opened the tunnel again, with all these strange,
+branching streams playing around inside."
+</P>
+
+<P>
+"But we reached here just in time!" declared Old Billee. "Now let's
+get t' th' bottom of this. We know there's a main stream, an' two
+branching streams. One of th' branching streams is controlled by th'
+water gate with th' copper handle."
+</P>
+
+<P>
+"And there must be another gate here, or else Del Pinzo and his crowd
+couldn't have shut off the water as they did before they ran away,"
+went on Bud. "There must be a whole maze of water-courses in this old
+tunnel. Probably the Aztecs dug 'em to save their gold and other
+valuables. But I'd like to know what that roaring is?" and as Bud and
+the others listened they could hear a subdued murmur, a rumbling and
+roaring sound, that seemed to shake the whole tunnel near where they
+stood.
+</P>
+
+<P>
+"Maybe this leads to it," suggested Dick, as he walked along and
+suddenly flashed his lantern across another opening&mdash;a natural stairway
+leading down into black depths.
+</P>
+
+<P>
+"Let's try it," said Bud.
+</P>
+
+<P>
+Down it they went, one at a time, carrying their lanterns. And as they
+advanced, descending until they came to a level passage, the murmur and
+roaring became louder.
+</P>
+
+<P>
+"Would you look at that!" suddenly cried. Bud, in an awe-stricken
+voice, as he came to a stop and pointed ahead.
+</P>
+
+<P>
+And then, as the others gathered about him and looked, they saw a
+wondrous sight.
+</P>
+
+<P>
+They had entered a cavern, similar to the one where Nort had been
+found, but not so large. And from the very centre, it appeared, of the
+uneven rocky floor of the cave there spouted out a stream of water
+about three inches in diameter.
+</P>
+
+<P>
+Solid white was this stream of water, like a bar of glass, and it shot
+out of a round hole in the floor as a stream comes from the nozzle of a
+fire hose. It was inclined at an angle of about forty-five degrees,
+was this strange stream of water, and whence it came and whither it
+went to the boys and their friends could only guess.
+</P>
+
+<P>
+It was this powerful, rushing stream, under immense head and power it
+seemed, that caused the rumbling, roaring sound. It appeared to strike
+against some rocky wall a long distance off, so far that the light of
+the lanterns could not penetrate to it, and the searchers did not feel
+like venturing beyond the point where the terrific stream issued.
+</P>
+
+<P>
+That it was of awful power was evidenced a moment later, for Bud, who
+had picked up one of the bars of iron, used by the conspirators to set
+their sinister mine, approached the stream and, raising the bar,
+brought it down with all his force on the white, spurting jet.
+</P>
+
+<P>
+On an instant the heavy rod was torn from his grasp, and whirled
+forward into the blackness beyond. There was a ringing, metallic sound
+as it hit some distant rock, and then it came bounding back, sliding
+across the rocky floor to the very feet of the searchers.
+</P>
+
+<P>
+"Look at that!" murmured Bud, as he stooped and picked up the bar. It
+was bent and twisted into a sort of combined S and U shape, mute
+evidence of the terrific power of the stream.
+</P>
+
+<P>
+"That would bore right through a man!" said Dick.
+</P>
+
+<P>
+"Like making a hole in cheese!" added Old Billee. "This is a terrible
+place! Let's get out!"
+</P>

+</H3>
+
+<P>
+Leaving behind them the roaring, rumbling jet of white water that came
+from the unknown and went thitherward, the boy ranchers and their
+friends made their way back to the main tunnel.
+</P>
+
+<P>
+"Well, there are two things we have to settle," declared Bud, when they
+had sat down on convenient rocks, near the running stream, and began to
+consider matters.
+</P>
+
+<P>
+"What are they?" asked "Nort.
+</P>
+
+<P>
+"One is, what effect has the turning of that lever we worked on the
+main stream? The other is, where is the lever that Del Pinzo and his
+gang shifted to cause this second branch stream to stop running?"
+</P>
+
+<P>
+"And when we find answers to those two questions," said Dick, "I think
+we'll have solved the mystery."
+</P>
+
+<P>
+"Right!" cried Bud. "So let's get at them. In the first place some of
+us will go back and shift the lever on the big rock in the first cave,
+while some of us stay here to see what happens."
+</P>
+
+<P>
+The party was divided and when watches had been adjusted to mark the
+same time, so it might be known how many minutes elapsed between the
+shifting of the lever and any noticeable effect, Dick, Old Billee and
+Snake went to the first cave&mdash;that of the huge boulder.
+</P>
+
+<P>
+It did not take long to demonstrate that when the water flowed from the
+main stream into that side branch, the stream nearer the river end of
+the tunnel went dry. But even with that no water passed along the main
+tunnel so that it would flow into the reservoir of Flume Valley.
+</P>
+
+<P>
+"The water must flow out of the first big cave by some outlet we know
+nothing about," decided Bud. "Now we'll look for the second water
+gate."
+</P>
+
+<P>
+They found the lever that controlled this in a corner of the upper,
+rocky room where Del Pinzo and his conspirators had been plotting when
+discovered. And when this lever was pulled from the position in which
+the seekers found it after the Mexican half-breed fled, the second
+stream (by which I mean the one nearest the river end of the tunnel)
+filled with water. But this did not affect the first.
+</P>
+
+<P>
+And not until both levers were set at positions which caused the branch
+streams to empty, did any water fill the end of the tunnel near Bud's
+ranch.
+</P>
+
+<P>
+But when this had been done; when the secret of working the levers was
+discovered, and water was once again flowing along the valley end of
+the tunnel, where the stream bed had been dry for two days, then Bud
+cried:
+</P>
+
+<P>
+"The fight is over and we've won!"
+</P>
+
+<P>
+"I wouldn't say that yet," spoke Old Billee cautiously, "Del Pinzo an'
+Hank Fisher are still around an' above ground. But I guess you've put
+a crimp in 'em, boys!"
+</P>
+
+<P>
+"I reckon!" shouted Yellin' Kid. "But are we sure that the water now
+goes to Flume Valley?"
+</P>
+
+<P>
+"We'll soon find out," declared Bud. "We're almost out of the tunnel
+now, and we can 'phone back and ask."
+</P>
+
+<P>
+And a little later they did emerge from the mysterious underground
+tunnel, with its still stranger water courses. But what was their
+surprise to find that night had fallen&mdash;in fact it was not exactly
+night, but nearly morning of the next day.
+</P>
+
+<P>
+For a moment coming out into the dark night bewildered them. And then,
+as they stood at the mouth of the mysterious tunnel under the mountain,
+there was a sharp crack.
+</P>
+
+<P>
+"Look out!" yelled Bud, as a bullet "zinged" viciously over their heads.
+</P>
+
+<P>
+In an instant Old Billee had whipped out his gun and sent a shot toward
+a group of horsemen along the river bank.
+</P>
+
+<P>
+"There they are! Del Pinzo and his gang!" yelled Dick, as another
+bullet sang over his head. "Come on! Let's get 'em!"
+</P>
+
+<P>
+"No use!" drawled Snake. "They've got hosses&mdash;we ain't!"
+</P>
+
+<P>
+And a moment later the gang of conspirators, firing another harmless
+shot, swept out of view.
+</P>
+
+<P>
+A group of men swarmed from the store and adjacent shacks, roused by
+the early-morning shooting, and with amazement they greeted our friends
+and heard the strange story.
+</P>
+
+<P>
+"What day is it?" asked Bud.
+</P>
+
+<P>
+"Friday," some one answered.
+</P>
+
+<P>
+The mystery-solvers looked at one another in amazement.
+</P>
+
+<P>
+They had been in the tunnel nearly forty-eight hours without sleep, nor
+did they feel the need of it, so exciting were the events that
+transpired.
+</P>
+
+<P>
+But late, or, rather, early as it was, they managed to get in the store
+to use the telephone. And when the gray dawn was breaking across Pocut
+River, Bud learned, over the wire, from one of his father's cowboys
+left at Flume Valley, that the reservoir was again being filled.
+</P>
+
+<P>
+"Hurray! It's all right!" yelled Bud, almost as loudly as the Kid
+would have done. "I guess, from now on, we'll have no trouble. But
+I'm going to see if we can't get Del Pinzo. He and his gang certainly
+tried to blow up the place, and us with it."
+</P>
+
+<P>
+"To say nothing of trying, as I believe, to drown, us like rats in
+there, by shutting off and turning on those queer streams," added Nort.
+</P>
+
+<P>
+"Do you think they really meant to drown us or blow us up?" asked Dick.
+</P>
+
+<P>
+That question was never answered, for Del Pinzo and his more intimate
+associates disappeared after their flight from the tunnel, when they
+fled following the shifting of the lever and the lighting of the fuse.
+</P>
+
+<P>
+There was dynamite tamped in among the rocks, and but for the stamping
+out of the fuse the tunnel never would have carried any more water to
+Flume Valley, and those in it might never have come out.
+</P>
+
+<P>
+Hank Fisher stoutly denied that Del Pinzo was acting for him either in
+planting the explosives or in shutting off the water from the reservoir
+of the boy ranchers. But everyone had their suspicions.
+</P>
+
+<P>
+For that it was Del Pinzo who had sent, or caused to be sent the
+mysterious warnings, no one doubted. Nor did anyone doubt but that the
+vicious Mexican half-breed had played tricks with the water.
+</P>
+
+<P>
+For that is what they amounted to&mdash;tricks. Who built the
+copper-lever-controlled water gates, putting them in to utilize the
+winding underground streams, no one could tell. It may have been the
+Aztecs. The powerful, slanting stream of water, it was discovered,
+formed the outlet of the shunted-in-river stream when the two side
+channels were opened so that Flume Valley's water supply was cut off.
+</P>
+
+<P>
+The water gates and the underground streams formed the chief mystery,
+and these never could be fully explored. It was thought too dangerous.
+How Del Pinzo discovered the workings of the levers, utilizing them to
+try to end the rule of the boy ranchers in Flume Valley, was not
+disclosed for many years.
+</P>
+
+<P>
+"You won't have any further trouble, now that the gates are closed and
+the levers taken off," Mr. Merkel said, for that had been done.
+"You'll get all the water you want in Flume Valley."
+</P>
+
+<P>
+"Guess I'll call it Happy Valley," said Bud, "for everything is coming
+out right, now."
+</P>
+
+<P>
+"In spite of black rabbits!" chuckled Old Billee.
+</P>
+
+<P>
+"Yes, even with black jacks!" laughed Bud. "Everything is working
+fine, now."
+</P>
+
+<P>
+And so it was. For with the discovery of the secret water gates and
+the disappearance of Del Pinzo, the epidemic died away. Though this,
+of course, was due to the arrest of Pocut Pete.
+</P>
+
+<P>
+That scoundrel was found guilty and sentenced to a long term in prison.
+But he kept his counsel, and never actually confessed that it was Hank
+Fisher who set him to this dastardly trick&mdash;if, indeed, it was that
+unscrupulous ranchman of Double Z.
+</P>
+
+<P>
+That it was rustlers from Double Z who had tried to drive off some of
+the boy ranchers' cattle was not doubted, the finding of the branding
+iron being regarded as telltale evidence. But this was not enough to
+cause any arrests.
+</P>
+
+<P>
+"Well, what are we going to do next?" asked Dick, of his brother and
+cousin, when they were fishing in the reservoir one evening, as, with
+the closing of the hidden gates and the uninterrupted flow of the
+water, many more finny prizes could be hooked.
+</P>
+
+<P>
+"Get ready for a big shipment of cattle," said Bud. "I never saw any
+finer stock than we have here in Happy Valley. That's our next
+move&mdash;reap the benefits of our hard work."
+</P>
+
+<P>

+"Who's that down at camp?" asked Dick, as he pulled up a good-sized
+fish and put it beside him on the grass.
+</P>
+
+<P>
+"Looks like Nell and your mother," said Nort to Bud.
+</P>
+
+<P>
+"It is!" Bud cried. "They said they'd come over, and Nell promised to
+bring a pie! Come on; we got enough fish!"
+</P>
+
+<P>
+And down the reservoir rushed the boy ranchers to greet their visitors.
+</P>
+
+<P>
+"Any pie, Nell?" cried Bud.
+</P>
+
+<P>
+"Sure," was the answer. "But it's for company&mdash;Dick and Nort!"
+</P>
+
+<P>
+"Ho! I'd like to see 'em grab it all!" challenged Bud, as he reached
+for the basket his sister held. "By Zip Foster I would!"
+</P>
+
+<P>
+"Say, who is Zip Foster anyhow?" demanded Nort.
+</P>
+
+<P>
+"Oh, I'll tell you&mdash;later!" chuckled Bud, and, as he removed the cover
+of the basket, delighted "Oh!" and "Ah!" exclamations came from him and
+his cousins at the sight within.
+</P>
+
+<P>
+Some of the cowboys came riding back to camp from the round-up, Old
+Billee cheerfully chanting:
+</P>
+
+<P>
+"Oh, bury me deep on th' lone prairie!"<BR>
+</P>
+
+<P>
+</P>
+

+And with this happy mingling of the joyful and sad we will take leave
+of the boy ranchers for a time.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at https://www.pglaf.org.

+CHAPTER I
+
+A MYSTERIOUS DISAPPEARANCE
+
+"Look out there, Bud! Look out! There you go!"
+
+"Side-stepping soap dishes! What's the idea? Whoa, there, Sock!"
+
+The pinto pony reared, swerved sharply to one side as a black streak
+shot across the trail almost under his feet and then, when the animal
+came to a sudden stop, there shot over his head the boy who had given
+vent to the last exclamation.
+
+Bud Merkel came down sprawling on all fours in a bunch of grass which
+served, in a great measure, to break the force of the catapult over his
+pony's head. And then, as the lad righted himself and limped over to
+catch his steed, he cried:
+
+"What in the name of the petrified prune pie was that, Billee?"
+
+"A jack, Bud! A jack rabbit, and as black as gunpowder! Yo' shore are
+in for some bad luck, now!"
+
+"Bad luck! I should say so! Almost breaking my neck, and laming
+Sock," and the lad looked anxiously at his pinto, being relieved to
+find, however, that the animal had suffered no harm.
+
+"But this won't be all!" declared Billee Dobb. "I never see a black
+jack shoot in front of a man yet that bad luck didn't follow!"
+
+"Well, let's make it go some to catch us!" suggested Bud as he leaped
+to the saddle, after making sure that the girths were tight. "Black
+jack! First one I ever saw," and he looked off in the distance toward
+a streak of dust, which was all that now represented the frightened
+rabbit that had shot across the trail so unexpectedly.
+
+"They aren't plentiful; thank your stars!" exclaimed the old cowboy.
+"I'm glad it didn't happen to _me_."
+
+"Yes, if you'd a' toppled over your critter's head there'd be a bigger
+crack in the ground!" laughed Bud, as he looked at his companion's
+greater girth and weight. "It came as sudden as a flash of lightning,
+that jack!"
+
+"Bad luck allers does come that-a-way," croaked Old Billee Dobb.
+
+"Oh, you and your bad luck!" laughed Bud. "Come on now, hump yourself!
+Hump yourself, you old soap-footing specimen of a slab of saltpeter!"
+he cried to his pony. "Mosey along!"
+
+"What's your rush, Bud? Anybody's take a notion t' think you was in
+suthin' of a hurry, t' hear you talkin' that-a-way t' your critter,"
+remarked Billee as he ambled along behind his more impetuous companion.
+
+"Hurry, Billee? Of course I'm in a hurry!" admitted Bud, a tall,
+well-tanned lad as he adjusted himself to his saddle, and dashed ahead
+of his companion on the dusty trail. "I reckon you'd be in a rush,
+too, if your cousins that you hadn't seen since last fall were coming
+to camp all summer with you!" and Bud Merkel swung around in his
+creaking saddle to note the pace of his companion.
+
+"Them two tenderfeet comin' out to Diamond X ag'in?" asked Old Billee
+Dobb.
+
+"Course they are!" answered Bud. "But they're a long shot from being
+tenderfeet, now, since they helped get rid of Del Pinzo and his
+cattle-rustling gang, and did their share in solving the mystery of the
+Triceratops. Tenderfeet! Guess you'd better not let 'em _hear_ you
+call 'em that!"
+
+"Mebby not, son! Mebby not!" agreed Old Billee, rather mildly as he
+tried to urge his slower-going animal to keep pace with Bud's. For the
+pinto, responding to the spur of voice and heel, had shot ahead. "I
+sorter forgot your cousins did have a hand in the lively doin's at
+Diamond X last season. So they're coming out again, be they?"
+
+"Yes, and we're going to make a camp of it, over in Flume Valley. I'm
+going to raise there the finest bunch of steers you ever hazed to the
+stock yards, and Nort and Dick are going to help me. I'm riding to
+meet them now at the water-hole, and we're going back to stay all
+summer in Flume Valley."
+
+"Hum! Flume Valley!" mused the older cowboy, for both riders were of
+that class, though Bud Merkel was the son of the man who owned Diamond
+X, and other important western ranches. "Flume Valley! That's where
+your paw started that irrigation scheme; ain't it?"
+
+"Yes," replied Bud. "It was only a waste bit of land before dad ran
+the water through the tunnel-flume from Pocut River, but now it grows
+the best grass you ever rolled your bed in. And the steers--you ought
+to see 'em, Billee!"
+
+"Well, I'm aimin' to, right soon," responded the old man. "Your paw
+was sayin' suthin' about putting me over there, but I didn't pay much
+attention to it. So you and the eastern lads are going to camp in
+Flume Valley, be you?"
+
+"Yes, because, being an experiment, dad didn't want to build any ranch
+houses there yet. But if we make good on the deal, and can raise
+steers on the grass that's grown since the water was let in, why, I'm
+to have it for my own ranch, when I come of age, and Dick and Nort will
+be my partners. We'll call it Diamond X Second."
+
+"Good name! Mighty good name! Look out there, you old piece of bacon
+fat!" he called sharply to his animal, pulling the pony quickly up as
+it stumbled. "There aren't any prairie dog holes here for you t' go
+puttin' your foot in! What's the matter of yo'?"
+
+But though Old Billee and Bud spoke thus in seeming harshness to their
+horses, there was no unkindness in their treatment of the animals. It
+was just their picturesque, western manner of talking, and hardly had
+the echo of Old Billee's words died away on the hot, dusty air than he
+was gently patting the neck of the pony he rode.
+
+"Did dad say you were to help me over in Flume Valley?" asked Bud, as
+he slowed down the pace of his animal to keep alongside that of the
+older cowboy.
+
+"Yes, he said I was to be your helper. And first I sorter hated to
+leave Babe, Slim, Snake and the rest of the bunch. But if you say your
+cousins are coming out, and if we can raise better cattle there than on
+the home ranch, why, mebby it won't be so worse."
+
+"Of course it won't!" cried Bud. "Why, even in the short time the
+steers have been in Flume Valley, Billee, they've improved."
+
+"You say there's stock there now?" asked the old man, for he was
+gray-haired, "Well, if they've been thrivin' by themselves so far,
+what's the good of you an' your cousins campin' there to watch 'em eat?"
+
+"Lots of reasons," answered Bud, as he and his companion started up a
+hill, on the other side of which they would reach the water-hole, where
+the main trail from Diamond X came in. "For one thing this is
+something new, and dad wants it watched carefully. Then, too, the
+water pipe and reservoir will need looking after. But, more than
+anything else, it's Del Pinzo and his gang of rustlers."
+
+"Those scoundrels didn't get what they deserved for tryin' to run off
+our stock last year!" complained Billee. "Now they're raisin' ructions
+again; be they?"
+
+"They sure are!" declared Bud. "It wasn't that they didn't get what
+they deserved, for they were sentenced to long terms. But the trouble
+was they didn't stay in jail where they were put."
+
+"I reckon they look at it just the other way!" chuckled Billee.
+
+"Yes," agreed Bud. "But it's going to make trouble for dad and all the
+other cattle raisers around here having that bunch of Mexicans and
+Greasers loose. That's one reason why we've got to watch out at Flume
+Valley, where we're going to try to raise some cattle that will beat
+those at Diamond X. I'm glad you're going to be with me, Billee."
+
+"Hum! You don't care what sort of trouble th' old man gits into; do
+you, Bud?" and he smiled a toothless smile at his employer's son.
+"Well, it's all in th' day's work, I reckon. But I'm not expected t'
+come with you to-night; am I? Slim said I was to report t' him at the
+main buildin's."
+
+"No, you don't have to come right away," replied Bud. "I'm to meet
+Dick and Nort at the water-hole--they were due at our ranch this
+morning--and you're to come when you can."
+
+"Might as well be quick as sooner," laughed the old cowboy. "I don't
+take much to new-fangled notions. But orders is orders, I reckon."
+
+"Oh, there isn't so much new at Flume Valley," said Bud. "All it ever
+needed to make one of the best places in this part of the country for
+raising cattle was water. Now, since dad had the big pipe flume put in
+from Pocut River, where it can fill the reservoir and water the grass
+and the cattle at the same time, things are going to boom!"
+
+"They are to hear you tell 'em!" chuckled Billee. "Well, I wish you
+all good luck, Bud, I'll help all I can. I'll be over to-night, if I
+can make it, though it's some of a ride after a day's work."
+
+"Oh, I won't expect you," said Bud. "I've got everything all laid out
+for the camp there. Nort and Dick will be with me, but we'll be on the
+lookout for you to-morrow. Bring what things you need, and some grub.
+And if my mother has any pies baked, just pack a few of them."
+
+"Only a _few_?" asked Billee, with a grin.
+
+"As many as Nell will let you take," laughed Bud. "But there's Nort
+and Dick! Whoop! Oh, boy! Come a-runnin'!" and the young rancher
+beat a tattoo with his heels on the sides of his steed, and raced down
+the slope toward two other lads who, like himself, were attired in
+conventional western costume. Old Billee pulled his steed to a halt
+and watched the greetings.
+
+"It's a great thing to be young!" sighed the old man. "The greatest
+thing in the world! But maybe I can do something yet! Only I don't
+like that black jack--I shore don't! Never heard of anythin' but bad
+luck followin' one of them nimble cusses! I don't like it for a cent!"
+
+"Well, here we are!" cried Nort Shannon, flinging his broad-brimmed hat
+into the air, and catching it on the end of his .45 before the
+headpiece could touch the ground.
+
+"Came right on time, too! Zip Foster couldn't 'a' made it better!"
+joyously declared Bud, clapping his palm into that of Nort.
+
+"Haven't you run him off the ranch yet?" asked the other lad, who was
+rather short and stout, not to say fat.
+
+"Run who off?" asked Bud.
+
+"Zip Foster!" repeated Dick. "Last I heard of him----"
+
+"Never mind _him_!" and Bud seemed somewhat annoyed at having mentioned
+the name. "Oh, but I'm glad you fellows are here! Have a good trip?
+Are you hungry? Did you have grub enough? Can you ride right out now?
+How's everybody at my house?"
+
+Nort looked at his western cousin, and then, with a deliberate motion
+pretended to mop his face free of some imaginary perspiration, brought
+out by the rapid-fire questions on his cousin's part.
+
+"Say! Go a bit easy, will you, Bud?" he begged. "One at a time! Line
+forms on this side!"
+
+"We're going right out with you, and everybody's fine!" answered Dick,
+summing up matters. "Your father said we were to ride out and meet you
+here at the water-hole. We've got as much of our outfits as we'll need
+for a few days, and so let's mosey along. Oh, but it's great to be
+back out west!"'
+
+"You got off a ripe one that time!" agreed Nort. "Who's that up
+there?" he asked, pointing to the figure of a solitary horseman on the
+hill down which Bud had ridden.
+
+"Looks like Yellin' Kid," commented Dick.
+
+"It's Old Billee," answered Bud. "He's going to be with us out at
+Flume Valley. Did dad tell you of the new venture?" he asked his
+cousins.
+
+"Yes, and it sounds good. Must have been quite a trick to bring water
+from Pocut River, Bud."
+
+"Well, it would have been if Professor Wright hadn't showed dad how to
+use an old underground water course for part of the way. Then it was
+easy. And say--you ought to see what a difference water has made in
+that valley! It was almost a desert before we irrigated."
+
+"I'm anxious to see it!" said Nort.
+
+"We can't get there any too soon to suit me," added Dick. "Just think!
+We're going to be our own bosses--boy ranchers for fair!"
+
+"You intimated plenty that time!" cried Bud. "Well, let's hit the
+trail!"
+
+The three boy ranchers started off, Nort and Dick accompanying Bud back
+over the way the latter had come. As they rode up the hill Old Billee
+passed on down another trail, leading to Diamond X proper.
+
+"Howdy, boys!" called the old cowboy from the distance to Nort and
+Dick. "See you a bit later over at your own ranch!" he added, and
+then, with a friendly wave of his hand, he went down into a little
+swale, or valley, and was lost to sight.
+
+"Now for some good times!" cried Bud, as he rode between his two
+eastern cousins, who had again come to spend the summer with him in the
+great western outdoors.
+
+"If it's anything like last year we sure will have a bang-up vacation!"
+declared Nort.
+
+"Well, I can't promise anything like that--with cattle rustling and
+digging up animals ten million years old," laughed Bud. "But I think
+we might have a little excitement."
+
+"How?" asked Nort and Dick eagerly.
+
+"Tell you later," promised Bud.
+
+They rode on, talking over old times and planning new ones, and as the
+shadows began to lengthen they rode down into a triangular valley, at
+one end of which a rude dam could be noticed, while, scattered over the
+green carpeted floor, were hundreds of grazing cattle.
+
+"Say, this is some slick place!" cried Dick.
+
+"The best ever!" affirmed Nort. "And is this where we are to camp and
+ranch it?"
+
+"Right here," declared Bud. "Course we haven't any ranch house yet.
+But we've got a tent--there it is," and he pointed to a white canvas
+shelter not far from the dam.
+
+"A tent! Oh, boy! better and better!" yelled Dick, as he urged his
+pony forward.
+
+As the three boy ranchers neared their headquarters, represented by two
+or three tents grouped together, there emerged from among them the
+figure of a man on horseback.
+
+"There's old Buck Tooth," said Bud.
+
+"Who?" asked the eastern cousins.
+
+"Buck Tooth--a Zuni Indian that dad picked up somewhere. He's one of
+the best herd-riders you'd want, and he and I are great friends.
+Wonder what's the matter, though? He acts as though something had
+happened."
+
+Bud pulled rein, to allow a better observation of the figure that was,
+obviously, riding out to meet him. Nort and Dick also halted their
+ponies. But Buck Tooth rode to meet them at great speed, sitting in
+the saddle as though part of it and the horse. He rode in a manner
+that made Nort and Dick envy him.
+
+"What's the matter, Buck?" asked Bud, as soon as the Indian was within
+hailing distance. And then Nort and Dick could see why he was called
+that. A large, yellow-stained tooth protruded from his mouth, giving
+him not exactly a pleasant expression.
+
+"What's wrong, Buck, you ride so _pronto_ like?" demanded the young
+western ranch boy.
+
+"Heap wrong!" came the answer in guttural tones. "You no shut off
+water in pipe; eh?"
+
+"Shut off the irrigation water? I should say not!" cried Bud. "Why,
+has anyone?"
+
+"Water no come! All gone! No run splash-splash now!" and Buck Tooth
+waved his hand toward the reservoir made by a dam that curved out in a
+half circle from the wall of natural rock.
+
+"The water gone!" cried Bud. "This is strange! Let's have a look!"
+
+He and his cousins rode at top speed to the reservoir that had
+reclaimed Flume Valley from the semi-desert it had long been.
+Dismounting, they climbed the slope and saw that from the great iron
+pipe, which was wont to spout a sparkling stream, there came only a few
+drops and trickles.
+
+"It's disappeared!" said Bud in a low voice. "The water has taken
+another course! This means the end of Flume Valley, I reckon!"
+
+
+
+
+CHAPTER II
+
+A NIGHT RIDE
+
+The boy ranchers stood looking down into the reservoir, which was
+almost full of water, but which was slowly running out through the
+different gates, some to concrete drinking troughs where thirsty cattle
+congregated, and some to distant meadows where it supplied moisture for
+the grass on which the steers of Diamond X Second fed. From the
+slightly ruffled surface of the reservoir, as the evening wind blew
+across the water, the gazes of Bud, Nort and Dick sought the faces of
+one another.
+
+"This looks had!" murmured Bud, while Buck Tooth, the Zuni Indian,
+grunted something in his own incomprehensible dialect.
+
+"What does it mean?" asked Nort, as he looked down the slope from the
+reservoir to the group of tents that was to form the home of himself,
+his brother and cousin for several months, while they were in camp.
+
+"It means the water supply, on which I depended to raise these steers,
+has petered out," answered Bud, and there was a worried note in his
+voice.
+
+"You mean stopped for good?" asked Dick.
+
+"I hope not," went on Bud. "But from what you can see--no water coming
+through the pipe line that dad laid to the Pocut River--I should say
+there was a break in it somewhere, and it will have to be fixed right
+away--that is, if I'm to keep these cattle here," and he looked down
+the valley where the bunches of steers were ever on the move, seeking
+new places to feed, or coming to drink water from the supply flowing
+out of the reservoir.
+
+"We seem to have struck a job right off the bat!" remarked Dick, as he
+picked up a stone and tossed it into the reservoir.
+
+"Just as we did when we came west before, and had to jump out and help
+the queer professors," added Nort. "But we're ready to go to work,
+Bud. All you'll have to do is say the word and----"
+
+But Bud did not seem to be paying much attention to what his cousin was
+saying. Instead his gaze followed that of his Zuni Indian helper.
+Buck Tooth was looking off up the hill under which the big pipe ran to
+the distant Pocut River on the other side of the mountain. And as Bud
+and Buck Tooth looked, and as the gaze of Nort and Dick was bent in the
+same direction, they all beheld a figure on the back of a fast-moving
+pony, riding up the trail that led over Snake Mountain.
+
+"Who's that, Buck? See him!" yelled Bud.
+
+"No can tell. Old Billee, mebby!" grunted the Indian.
+
+"No! Old Billee just left me! He's back at the ranch house. But
+that's a stranger, and I don't like strangers sneaking around my
+ranch--especially when there's a break just happened to my pipe line!"
+exclaimed Bud. "I'm going to look into this!"'
+
+"Hi there! Hold on a minute! I want to talk to you!" he yelled,
+making a megaphone of his hands and directing it at the figure on the
+back of the sturdy pony that was scrambling up the mountain trail.
+"Wait a minute!"
+
+But this the stranger seemed unwilling to do. The watching group near
+the reservoir saw him raise his quirt, or short whip, and bring it down
+savagely on the back of the pony, which, already, was doing its best to
+carry its master out of distance.
+
+Then, with a quick motion, Bud drew his .45, and though both Nort and
+Dick saw him aim it high above the man's head, in order to shoot over
+him, horse and rider went down in a tumbled heap at the sound of the
+report, which followed as Bud pulled the trigger.
+
+"You've winged him!" cried Dick.
+
+"Shucks! Didn't mean to hit him--just shot to scare him!" declared
+Bud. "But we'll have to see about it now! Come on!" he cried, and he
+ran down the side of the reservoir to where he had left Sock, his pony,
+followed by Dick and Nort who also headed for their steeds.
+
+"Hu!" grunted the Indian, as he came on down more leisurely. "No
+water--man shot--new boys come--big time, mebby! Hu!"
+
+And Buck Tooth was more than right. Big times impended in Flume Valley.
+
+While Bud Merkel and his two cousins who had arrived from the east only
+the day before were mounting their ponies, to ride up the side of Snake
+Mountain, and seek the man Bud had shot, I shall have a chance to tell
+my new readers something about the boy ranchers, and the volume that
+immediately precedes this one.
+
+The book is entitled "The Boy Ranchers; or Solving the Mystery at
+Diamond X." Norton, or Nort, and Dick, or Richard, Shannon were sons
+of Mr. and Mrs. Thornton Shannon, and their home was in the cast. When
+Mr. Shannon, the summer previous, had been obliged to make a trip to
+South America, with his wife, he sent his sons to spend their vacation
+at Diamond X, one of the western cattle ranches owned by Henry Merkel,
+Mrs. Shannon's brother.
+
+Almost immediately on their arrival Nort and Dick, who were then
+rightly classed as "tenderfeet," became involved in a strange mystery.
+A call for help came, and they took part in the rescue of two college
+professors who had been attacked by a band of Mexicans and "Greasers,"
+the latter being a low-class Mexican.
+
+The professors were rescued, but the mystery only deepened. What it
+was, and how it came to be solved, you will find set down at length in
+the first volume. Sufficient to say, here, that Nort and Dick, as it
+were, "cut their eye teeth," during the exciting experiences that
+followed their arrival at Diamond X.
+
+The eastern boys learned how properly to ride a pony cowboy fashion,
+they learned the use of the branding iron, the lariat and "gun," as the
+.45 revolvers were universally called. They learned, also, how to
+"ride herd," "ride line" and how to live in the open, with the prairie
+grass for a bed and the star-studded sky for a blanket, their saddle
+forming the pillow.
+
+Mr. Merkel, Bud's father, owned several ranches besides Diamond X, so
+named because that brand was used on the cattle from it. He had Square
+M, and Triangle B, the explanation of which names are obvious.
+
+When it came time for Nort and Dick to return east, as winter
+approached, they left, promising to return as soon as their summer
+vacation should arrive, for they were determined to become boy ranchers
+in earnest, an ambition in which Bud shared.
+
+Now it was summer again, and Nort and Dick had once more journeyed to
+their uncle's ranch, to be met by Bud, as arranged, at the water-hole.
+For between the two visits of the easterners some changes had been made
+at Diamond X.
+
+Bud had been clamoring to be allowed to raise some cattle "on his own,"
+and his father had consented. Off to the north of Diamond X, and in a
+depression between the Snake Mountains on the east and Buffalo Ridge on
+the west, was another valley, well sheltered from the wintry blasts.
+This valley was owned by Mr. Merkel, and though part of it was
+timbered, and some scattered sections produced an excellent variety of
+grass for stock, there was no dependable source of drinking water
+available. And without water at hand it is impossible to raise cattle
+in the west--or any place else, for that matter.
+
+How to get water to "Flume Valley," as it came to be called, was a
+problem. It would have been put to use raising cattle long before this
+had Mr. Merkel been able to get any water there for the animals to
+drink, and also some to irrigate the more arid portions so that fodder
+would grow.
+
+At the foot of the eastern slope of Snake Mountains ran the Pocut
+River, which served to supply not only Diamond X, Square M and Triangle
+B ranches with water, but also those of Double Z and Circle T, the
+respective holdings of Hank Fisher and Thomas Ogden. But though Pocut
+River gave plenty of water to Bud's father and the other ranchmen, none
+was available for the isolated valley which, except for this, would
+have been an ideal place to raise steers.
+
+And it was here that the good services of Professor Wright, one of the
+scientists mentioned in the first volume, came into play. For
+Professor Wright discovered an ancient underground water course,
+connecting with Pocut River, and when this had been partly tunneled,
+re-opened at places where it had caved in, and a big iron pipe laid
+part of the way, water came gushing out into Flume Valley, as Bud
+renamed the place, it having been called Buffalo Wallow before that
+time; probably when there was water in it and the buffalo made it a
+rendezvous.
+
+And when the water came through the iron pipe, falling into the
+reservoir that had been built to hold it in reserve, Bud was allowed to
+begin his experiment in stock raising.
+
+His father provided him with the cattle, and Bud was a boy rancher in
+reality now. His cousins had agreed to help him in the venture on
+their arrival, and Bud had been expecting them when he rode out with
+Old Billee that day. Old Billee was one of the Diamond X cowboys, and
+he might have been made a foreman, except that he had no executive
+ability. He could do as he was told, and that was about all. He was
+reliable and dependable, but had no initiative for big undertakings.
+Old Billee, with Buck Tooth and some other cowboys, had been assigned
+to help Bud in his venture.
+
+As Bud has told his cousins, when he rode to meet them at the
+water-hole, on the trail from Diamond S ranch, there was no time, yet,
+to construct ranch houses in Flume Valley. Tents would have to serve
+the purpose, and the boys were rather pleased, than otherwise, with
+this.
+
+"It will be just like camp!" said Bud.
+
+And so the easterners had arrived, and, almost with the moment of their
+coming, there had begun the first act in what was to prove a drama of
+almost tragic happenings.
+
+"You stay at the camp, Buck!" called Bud to the Zuni, as the three boy
+ranchers mounted and prepared to ride up to where the unknown man had
+collapsed after Bud had fired. "You stick around! Old Billee, or some
+of the boys from Diamond X may ride over, though I don't expect them
+until morning. Stay here, Buck!"
+
+"Me stick!" gutturally answered the Indian. "You catchum man
+mebby--git back water."
+
+"Maybe," agreed Bud, as he and his cousins trotted off up the trail,
+which wound around the reservoir and over the mountain.
+
+Dusk was falling as the boys reached the vicinity of the place whence
+they had seen the lone rider emerge from the bushes, spurring his horse
+up the rocky trail that led over Snake Mountain, as the whole ridge was
+known.
+
+"Must have been about here," said Dick, as he reined in his steed, for
+which the panting animal, doubtless, was grateful.
+
+"Little farther on, I think," said his brother.
+
+"No, it was right here," declared Bud, as he dismounted and began to
+scan the ground. "Here's where his horse slipped," and he pointed to
+the tell-tale marks on the trail.
+
+"Yes, and look--you hit him all right!" added Dick.
+
+He indicated some dull, red spots on the stones. Bud reached down and
+gingerly touched them.
+
+"Blood!" he murmured. "Guess I did wing him--or the horse--but I don't
+see how I could. I fired high."
+
+"But where did he go?" asked Nort, following the marks left by a horse
+that had, obviously, been hard pressed. "See, the sign goes right up
+to this rocky wall, and then stops. He couldn't have gotten up there,
+could he?"
+
+"Not unless he wore wings," said Bud grimly. "But it's getting too
+dark to see well. We'd better be getting back to camp."
+
+"I thought you were going to follow this up, and see what had happened
+to your pipe line," suggested Dick.
+
+"I am, but we can't ride on without some grub. No telling what we may
+stack up against. We'll have to make a night ride of it, I'm thinking,
+and I'd like to have Buck Tooth along. He's a shark on following a
+blind trail. Come on, we'll go back to camp, get some grub and then
+take this up again. I hope I didn't kill him, though," murmured Bud,
+as he again leaped to the saddle, an example followed by Nort and Dick.
+
+"Who was he?" asked the latter, puffing slightly from his exertions,
+for he was much stouter than his brother Nort.
+
+"Search me!" replied Bud. "Looked mighty suspicious, though, the way
+he rode off. And if he wasn't up to something wrong he'd 'a' stopped
+when I hailed him."
+
+"Do you think he had anything to do with the break in the pipe?" asked
+Nort.
+
+"You've got me again," confessed his western cousin. "We'll have to
+make a night ride of it and find out."
+
+They rode back to the camp tents, to find Buck Tooth calmly smoking his
+red-stone Indian pipe, and gazing off in the darkening distance at
+nothing at all, as far as the boys could determine.
+
+"Anybody been around, Buck?" asked Bud.
+
+"Nope!" was the answer. "You catchum dead man?"
+
+"Not a sign, Buck! Beckon he must have dug a hole and pulled it in
+after him. But we've got to find out what's the matter with the pipe
+line. There's only a few days' supply of water in the reservoir.
+Rustle out some grub, and we'll ride over the mountain."
+
+"Um," grunted the Zuni, and a little later, after a hasty meal of
+flapjacks, bacon and coffee, the boy ranchers, with the old Zuni
+Indian, started on a night ride over the mountain trail, in the general
+direction of the pipe line, the supply of fluid for which had so
+mysteriously stopped.
+
+But strange events were only just beginning to happen in Flume Valley.
+There were others in store for the boy ranchers.
+
+
+
+
+CHAPTER III
+
+THE WARNING
+
+"Will it be safe to leave our camp alone, like this?" asked Nort, as he
+and his companions rode off, leaving behind them the white tents,
+gleaming in the wondrous light of a full moon.
+
+"Why not?" inquired Bud. "It won't walk away."
+
+"No, but some one might come in and take everything."
+
+"There isn't much worth taking. You brought your old stuff with you,
+we have our ponies, so all they could snibby would be the camp dishes,
+and they aren't worth the risk."
+
+"Could they drive off any of your cattle?" asked Dick.
+
+"Why don't you say _our_ cattle?" asked Bud with a smile, which was
+plainly to be seen in the brilliant moonlight. "You fellows are in
+this venture with me, you know."
+
+"We haven't yet gotten used to thinking of it that way," remarked Nort,
+as he rode beside Buck Tooth. The old Zuni Indian managed to keep pace
+beside the boys without ever urging his pony forward, a trick of riding
+which even Bud envied.
+
+"Well, you'd _better_ get used to it," was the laughing retort. "Your
+dad staked you to part of the expenses of this deal, same as mine did
+me, and of course you'll share in the profits--if there are any," Bud
+added rather dubiously. "And if we don't get that water back there
+won't be enough to make you need a hat to carry 'em off."
+
+"As bad as that?" inquired Nort.
+
+"Oh, I'm not saying it's bad--_yet_!" exclaimed Bud. "There may be
+just a stoppage in the pipe, which can easily be cleaned out. Or, it
+may be--something else."
+
+But what else it might be he did not say, and Nort and Dick were not
+sufficiently familiar with irrigation and flume lines to hazard a
+guess. But they knew enough about their cousin to tell that he was
+worried.
+
+"What do you plan to do?" asked Dick, as the four rode on, their ponies
+occasionally stumbling as they mounted the rocky trail that led over
+Snake Mountain. "Look for that man--the one you----"
+
+"The one I _didn't_ shoot!" interrupted Bud. "I'm as sure I didn't hit
+him as I am that we four are here this minute. I know I fired too
+high!"
+
+"Unless the bullet hit a rock and glanced down," suggested Nort.
+
+"Well, yes, that may have happened," admitted Bud. "But if he was
+badly hurt he couldn't get away, as he did."
+
+"Could he have fallen into any hole or gully?" asked Dick. "We didn't
+look for that."
+
+"He might have," admitted the western lad. "But what I'm looking for,
+now, isn't that fellow, who may or may not be shot, but for the break
+in my flume--that's what I want to locate. Once I get the water so
+it's running back in my reservoir I'll feel better. For if there's a
+permanent shut-off we might as well move out of Flume Valley," he went
+on. "The cattle would just naturally die of thirst!"
+
+"Isn't there any water at all?" asked Nort, as he pulled his pony up
+sharply when the animal stumbled.
+
+"Not enough to water all the stock I aim to raise," answered Bud. "At
+the far end of the valley--away from our camp--the grass grows pretty
+well, for some rain does fall there once in a while. But there isn't a
+water-hole worth the name, and you know what happens to cattle when
+they can't get a drink!"
+
+"I should say so!" commented Nort, for he and his brother had seen some
+of the terrible suffering caused by animals having to be driven long
+distances without any water being available. "Then the pipe line is
+your only hope?"
+
+"That, and the ancient underground watercourse it connects with to
+bring water from the Pocut River," replied Bud. "You see, there's a
+sort of natural tunnel under the mountain, and this was once an old
+river bed. I suppose, or at least Professor Wright has told us, that
+once this tunnel was full-up with water. But there was a change in the
+direction of the old stream, and the water tunnel dried up. However,
+it didn't cave in, except in a few places, and we now use it to bring
+water to Flume Valley. There is really only a comparatively short
+length of pipe at either end, one end being where the water from the
+Pocut River enters, and the other where the pipe delivers the water to
+our reservoir."
+
+"How are you going to find the break?" asked Dick.
+
+"Or stoppage?" suggested Nort.
+
+"Well, I aim to ride over the mountain tonight," answered Bud, "and see
+if all is clear at the river intake end of the line. If it is, I'll
+know there must be a stoppage, or break, somewhere inside the old water
+tunnel."
+
+"How you going to find that?" inquired Nort.
+
+"Why, we'll get lanterns and ride through," replied Bud. "That's easy!"
+
+"Ride through an underground river!" cried Dick. "You can't!"
+
+"No, we couldn't if the old underground river course was _full_,"
+agreed Bud, "but it _isn't_. There's only a comparatively small amount
+of water flowing through the old course, which is wide enough for two
+of us to ride or walk abreast, and twice as high as you need. I've
+ridden through more than once. It's like a long, natural tunnel under
+the mountain, with water flowing in the center depression, so to speak."
+
+"Must be rather spooky inside there," suggested Nort.
+
+"It is a little; and it's nearly an all-day's ride. But it's the only
+way to find the trouble. Professor Wright said that some day the water
+might work through, and go off on a new course, and in that case I'd be
+dished until I could stop up the break."
+
+"Well, we'll help all we can," offered Nort.
+
+"Sure thing!" echoed his brother.
+
+"We'd better take it a bit easy now," spoke Bud, as the ascent of the
+mountain became more steep. "We don't want to wind the ponies, and we
+may have a hard day ahead of us to-morrow."
+
+"It _is_ quite a climb," admitted Nort. "Are we going to ride all
+night?"
+
+"No, we'll turn in about midnight," said Bud. "But this will give us a
+start so we can get to the Pocut River end of the flume by morning. We
+can stop any time you fellows want to."
+
+"Oh, we aren't tired!" Dick hastened to say, a sentiment with which his
+brother agreed. "This is as much fun as riding herd, and driving off
+the cattle rustlers."
+
+"Glad you like it," commented Bud. "And the rustlers might as well
+drive off our stock, if we don't soon get this water to running again.
+Old Billee said I'd have bad luck when that black rabbit crossed my
+path, and it sure is coming!"
+
+"What black rabbit was that?" asked Nort, curiously.
+
+"One that gave me a tumble when I was riding to meet you," answered
+Bud. "I never saw one before, and I don't want to again. Not that I'm
+superstitious, but there sure is something queer about _this_! I don't
+like it for a cent!"
+
+The boy ranchers and the Zuni Indian rode on, mounting higher and
+higher along the mountain trail, heading for the summit. And when they
+reached it, and Bud, by a glance at his watch, announced that it was
+midnight, he followed with the suggestion that they camp there for the
+remainder of the night.
+
+"We can make the rest of the trip in a couple of hours, for it's down
+hill," he said.
+
+"Camp suits me," murmured Nort, and soon, after a bite to eat, they
+rolled themselves in their blankets, having tied the ponies to scrub
+bushes, and went to sleep. The riding of the boys, coupled with the
+pure air they had breathed, brought them slumber almost at once, and
+even Buck Tooth, alert as he usually was, neither saw nor heard
+anything of the sinister visitor who came softly upon the sleeping ones
+during the night hours.
+
+For there did come a visitor in the night, as evidenced by a scrawled
+warning, on a dirty piece of paper, fastened to a stubby tree by a
+long, sharp thorn.
+
+It was this fluttering bit of paper that caught Dick's eye when he
+awakened, rather lame and stiff, and stretched himself in his blanket
+as the sun shone in his eyes next morning.
+
+"Hello!" he cried, taking a hasty look around to see if Bud had,
+perchance, ridden away without awakening his companions, and had left
+this note to tell them so. "What's the idea?" and then Dick noticed
+that all three of his companions were stretched out near him, and the
+four ponies were standing together not far away.
+
+"What idea?" asked Bud, sitting up and rubbing his eyes.
+
+"That special delivery letter," and Dick pointed to it. "Wasn't here
+last night," he went on, "for I tied Blackie to that tree before I
+staked him out. What is it?"
+
+Bud rolled out of his blanket, and took the piece of paper from the
+tree.
+
+"It's a warning!" he announced.
+
+"A warning?" cried Nort and Dick, while Buck Tooth began making a fire.
+
+"Yes," went on the boy rancher. "Here's what it says:
+
+"'Don't take no more watter frum Pocut River if you want to stay
+healthy!'"
+
+"Whew!" whistled Dick. "What does that mean?"
+
+"Just what I'd like to know," said Bud, and then all three boys
+started, and looked toward the upward slope of the mountain, down which
+they had partly descended. For there came rolling toward them a mass
+of dirt and stones, indicating the approach of some one.
+
+
+
+
+CHAPTER IV
+
+A STRANGE REAPPEARANCE
+
+Characteristic it was of Bud Merkel, being a son of the west as he was,
+that his hand instinctively sought the leather holster whence protruded
+the grim, black handle of his .45. But he did not draw the weapon, nor
+did Nort or Dick pull theirs, which they had started to get out when
+they noted Bud's action.
+
+For Bud smiled when he had a glimpse of the newcomer, and Buck Tooth,
+who had glanced up from where he was making the fire, gave a grunt of
+welcome.
+
+"Babe!" exclaimed Nort, as he recognized the fat assistant foreman of
+Diamond X ranch. "Babe!"
+
+"Sure! Who'd you think it was?" came the smiling question. "Looks
+like you had an idea it might be one of them rustlers that made trouble
+when you fellers was here before! Eh?
+
+"Glad t' see you two _ex_-tenderfeet," and Babe Milton grinned broadly
+as he accented the _ex_, and held out a welcoming hand to Nort and
+Dick. "They said you was comin' back to Diamond X, but I sorter missed
+you--been out tryin' t' locate a bunch of strays," he confided to Bud,
+"an' I didn't have no luck! Glad to meet yo' all, though, powerful
+glad! 'Specially on account of that there coffee!" and he sniffed the
+air as he caught the aroma of the fragrant pot Buck Tooth was putting
+on to boil.
+
+"But what are you lads doing so far from Diamond X?" Babe went on, when
+they had moved over to the camp fire, the blaze of which was genially
+warm this cool morning on the mountain.
+
+"We aren't stopping there this trip," said Nort.
+
+"We're 'on our own,'" proceeded Bud. "I'm raising cattle in the old
+Buffalo Wallow Valley--Flume I call it now."
+
+"Oh, yes, I did hear you were going to tackle that," spoke Babe.
+"Didn't know you'd got stocked up, though. Well, I've been over at
+Square M for so long I don't hear no real news no more. Gosh! But we
+did have some excitement the time those professor chaps pulled that
+_Trombone_ out of the ground; didn't we, Bud?" he chuckled.
+
+"Triceratops, Babe! Triceratops!" corrected Bud, laughing at the
+expression of the fat assistant foreman's face.
+
+"I never could remember the name of them musical pieces, nohow!" sighed
+Babe. "Fond as I am, too, of singing," and, taking a long breath, he
+bellowed forth on the unoffensive morning air this portion of a ballad:
+
+ "Sing me to sleep with a spur for a rattle,
+ Fill up the biscuits with lead.
+ Coil me a rope 'round th' ole weepin' willow,
+ Curl my feet under my head!"
+
+
+"Glad you feel that way about it," remarked Bud, rather soberly, as
+they squatted around the fire for breakfast, which Buck Tooth seemed to
+have prepared in record time.
+
+"What's bit you?" asked Babe, pausing with a smoking flapjack half way
+to his mouth, while in his other hand he held a steaming tin cup of
+coffee. "Git out th' wrong side of th' saddle this mornin'?"
+
+"No, but there's trouble over at the valley," explained Bud. "The
+water has stopped running and----"
+
+"The _water_ stopped running!" interrupted Babe.
+
+"Yes, and when we start out, intending to see what's the trouble, we
+get this warning," and Bud extended the dirty piece of paper that had
+been fastened to the tree with the thorn.
+
+"Whew-ee-ee!" whistled Babe, as he read the scrawl of misspelled words.
+He opened his mouth again, to intone another of the hundred or more
+verses of his favorite cowboy song, but Bud motioned to him to refrain.
+
+"Don't you like my singin'?" asked Babe, a bit hurt.
+
+"Yes, but I want to ask you some questions," went on Bud. "You say
+you've been out looking for strays?"
+
+"Yep; prospectin' up and down Snake Mountain all yist'day an' part of
+th' night. My grub giv' out with supper last night, an' I was hopin' I
+might even run into a bunch of Greasers, when I saw you folks spreadin'
+th' banquet table here."
+
+"Glad you joined us," remarked Nort.
+
+"So'm I," mumbled Babe, his mouth full of bacon and flapjacks. "But
+what's your questions, Bud? Shoot!"
+
+"Did you see anybody who might have written this?" and the boy rancher
+again read the sinister warning:
+
+
+"'Don't take no more watter frum Pocut River if you want to stay
+healthy.'"
+
+
+"Why, no, I didn't see nobody," spoke Babe, with more force than
+grammar. "'Tain't a joke; is it?"
+
+"Not when I tell you the water has stopped running," said Bud.
+
+"So you did! Hum, that's mighty queer like!" mused the assistant
+foreman, who had, early in the spring, been transferred to Mr. Merkel's
+Square M ranch from Diamond X. "But some of us rather thought there'd
+be trouble when your paw dammed up the river to shunt some of it
+through the old water course over to Buffalo Wallow. Hank Fisher
+claims his water supply has been lessened by what your paw did, Bud."
+
+"That's all bosh!" exclaimed Bud. "There's as much water for Hank
+Fisher as he ever had at Double Z. Besides, this isn't his way of
+doing business. He's as mean as they make 'em, but he'll come out in
+the open and tell you what he thinks of you."
+
+"Yes, Hank is that way--_sometimes_," agreed Babe cautiously. "At th'
+same time I wouldn't put it past him. Better tell your paw about this,
+Bud. You got grit--all three of you!" and he included the other boys
+in his glance. "But you can't fight Hank Fisher, Del Pinzo and that
+onery gang of Greasers and Mexicans!"
+
+"There!" cried Nort, clapping his hand down on his outstretched leg.
+"That's who that man was--Del Pinzo!"
+
+"What man?" asked Babe.
+
+"The one Bud shot."
+
+"What's that?" cried Babe, half starting to his feet. "Did you shoot
+somebody?"
+
+"Well, I may have _creased_ him," admitted the boy, using a word to
+denote a grazing bullet wound, hardly more than a scratch.
+
+"Whew-ee-ee!" whistled Babe again. "This sounds like old times! Let's
+have the hull yarn, Buddy!" he appealed.
+
+Whereupon Bud related how he had ridden from his new ranch--Diamond X
+Second--to meet his cousins whom he expected. He told of finding the
+stream of water shut off, of the appearance of the man, the shot, his
+sudden vanishing, and the subsequent night ride of the boys.
+
+"That was Del Pinzo, I'm sure of it!" declared Nort. "I was trying to
+think where I'd seen him before, and now I remember!"
+
+"You couldn't very well forget Del Pinzo," declared Bud. "But this
+wasn't he. That isn't saying that it might not have been, of course,"
+he added, "for I understand he broke jail, after they caught him and
+sent him up for rustling our cattle. No, this wasn't that slick
+Mexican, Nort."
+
+"Who was it?" asked Babe, helping himself to another of the flapjacks
+which Buck was making in a skillet over the greasewood fire.
+
+"That's what we don't know," said Bud. "He just naturally vanished,
+the way my water did. What are you going to do, Babe?"
+
+"Well, I ought t' keep on lookin' for them strays your paw's so anxious
+about," was the answer. "But I reckon I got time t' mosey along with
+you. You say you're goin' down to the river?"
+
+"Yes, to see if there's anything wrong at the intake pipe," Bud
+answered.
+
+"Then I'll go with you," offered Babe. "And before you try that ride
+through the old water course, under the mountain, you'd better call up
+your paw."
+
+"What for?" Bud wanted to know.
+
+"Well, he mightn't altogether like it. There's a risk, an' he may want
+t' send some of us with you. It's easy t' get him on the 'phone from
+the dam."
+
+"Yes," agreed Bud, "I s'pose I had better do that." He remembered that
+where Pocut River had been dammed to enable water to flow into the pipe
+line, and then through the old river course to his reservoir, there was
+a general store, which boasted of a telephone.
+
+A little later, breakfast having been finished, the party, now
+including Babe, reached the Pocut River. There an inspection showed
+the water from the river above the dam running freely into the pipe
+that carried it to Flume Valley.
+
+"Nothing wrong here," remarked Bud as he looked into the dark tunnel
+which received one end of the pipe. And it was through this natural
+tunnel, extending under the mountain, being the course of an old
+stream, that the boy ranchers proposed riding.
+
+"No, th' trouble must be somewhere inside," agreed Babe. "But call up
+your paw, Bud."
+
+Which Bud did, learning from his father at Diamond X, that Old Billee
+had departed, early that morning, to take up his abode at the camp in
+the valley.
+
+"Better wait until Old Billee reaches your place, and then call him
+up," suggested Mr. Merkel to his son over the wire, for there was a
+'phone in Bud's camp. It seemed rather an incongruity, but it was a
+great convenience, since it connected directly with Diamond X, Triangle
+B and Square M ranches, as well as with the regular lines.
+
+There was nothing to do but wait until Old Billee might be expected to
+have reached the camp in Flume Valley, and after several hours Bud
+called up his own new ranch headquarters.
+
+"They don't answer," Central reported.
+
+"He's taking his time," commented Babe.
+
+But an hour or so later, after several other trials, the voice of Old
+Billee came back over the wire from miles distant.
+
+"Hello! Hello there! Wassa matter? Wassa matter?" demanded the voice
+of the old cowpuncher. "Where's everybody, anyhow? Nobody here but
+me!"
+
+"We're over at the dam--Pocut River," called Bud into the instrument.
+"Say, Billee, something happened at my place last night. The water
+stopped, and we came over here to see where the stoppage was. But it's
+all right here. How about you there?"
+
+"All serene here, Bud, all serene! Wait a minute and I'll take a look
+at your reservoir. I can see it from the tent where you got this
+talkin' contraption strung. You say the water stopped last night?"
+
+"Stopped complete, Billee," Bud answered back over the wire.
+
+"Well then, if there's any comin' over the spillway, now, it's a sign
+she's runnin' here ag'in, I take it!"
+
+"Sure thing. But is she running?" asked Bud, anxiously.
+
+"Wait a minute, an' I'll take a look. Hold on to that there wire!"
+
+"I'll hold it!" promised Bud, smiling at his cousins.
+
+There was a moment of anxious waiting and, in fancy, the boy ranchers
+could see Old Billee going to the tent flap and looking toward the
+reservoir.
+
+"Hello, Bud!" presently came the call over the wire.
+
+"Hello, Billee. What about it?"
+
+"Water's there all right! Must 'a' come back in th' night! She's
+runnin' fine now!"
+
+
+
+
+CHAPTER V
+
+ANOTHER WARNING
+
+Bud Merkel was about to hang up the receiver, with a blank and
+uncomprehending look on his face, when Babe caught the black rubber
+earpiece from him.
+
+"Wait a minute, Billee!" called Babe into the transmitter. "See
+anything of anybody around there? Anything suspicious?"
+
+The others could not hear what the old cowboy's answer was, but Babe
+soon enlightened them.
+
+"He says it's all serene," Babe declared as he now hung up the
+receiver. "Nobody in sight, an' the water is runnin' through the pipe
+as natural as can be."
+
+"I can't understand it!" declared Bud. "It was almost as dry as a bone
+when we left last night."
+
+"But it's running in here from the river dam," said Nort.
+
+"Then there must have been a break somewhere in the tunnel natural
+water course," declared Bud. "Well, if it mended itself so much the
+better. But that doesn't explain this," and he held out the scrawled
+warning. "And if the water stopped once it may stop again."
+
+"Yes," agreed Babe, "but if anybody wanted to stop it they'd have to do
+it either at this end, where the pipe takes water from the river, or at
+your end, Bud, where it delivers water to your reservoir."
+
+"Unless somebody stopped the stream inside the tunnel," suggested Dick.
+
+"Then it would back up here at the river end," said Nort, quickly, "and
+it hasn't done that."
+
+"No, it hasn't," agreed Bud. "It sure is queer. I'm beginning to
+think there may be more in that black rabbit than I believed first."
+
+"What rabbit is that?" asked Babe.
+
+"The one Old Billee said would bring me bad luck," Bud answered.
+"Well," he went on to his cousins, "we might as well go back to camp.
+We can't do anything here."
+
+"If you've got water that's all you want in Flume Valley," declared
+Babe. "There isn't a finer place t' raise cattle in all th' world than
+there--if you have _water_!"
+
+"And if you haven't--you might as well quit!" spoke Bud.
+
+"You eliminated an earful that time," the assistant foreman stated.
+"But I reckon it was just a little break, inside th' tunnel, an' it
+filled itself up natural like. You won't have any more trouble."
+
+"I hope not," spoke the boy rancher. "Are you going on back to Diamond
+X, Babe?"
+
+"Not until I find that bunch of strays from Square M. They're too
+valuable t' let slip."
+
+"Especially to let Hank Fisher, or Del Pinzo, slip them away,"
+exclaimed Bud as he and his chums left the store where they had been
+telephoning.
+
+"Not so loud! Not so loud!" cautioned Babe.
+
+"Why not?" Bud wanted to know, when they were outside.
+
+"'Cause one of Hank's men was in there! He'll be sure t' tell what you
+said, Bud."
+
+"Let him! I'm not afraid of Hank, or his tool Del Pinzo, and I'd just
+as soon either one would know what I think of 'em!"
+
+"Don't be too brash; don't be too brash!" counseled Babe. "But they
+sure are both bad actors--Del an' Hank!"
+
+There was nothing more that needed to, or could, be done at the Pocut
+River end of the flume, part natural, part artificial, which supplied
+Bud's new ranch with such a vital necessity as water. The stream had
+been dammed just above the intake pipe--not completely dammed, but
+enough to provide the necessary head of water.
+
+As Nort had said, had the stream been stopped purposely or by accident
+inside the tunnel, the water would have backed up and run out around
+the pipe, flowing into the river below the dam. But this had not
+occurred.
+
+"If it doesn't happen again we'll be all right," spoke Bud, as he rode
+back with his cousins, making an easy pace along the trail that led
+over Snake Mountain and down into Flume Valley. "But if the water
+stops running again----"
+
+"Let's go through the tunnel; it's the only way to be sure!"
+interrupted Nort.
+
+"I'm with you!" exclaimed Dick.
+
+"It would seem to be the only way," agreed Bud. "Well, we'll hope this
+is the end of my black-rabbit bad luck, and look for success, now that
+you fellows are here. Cracky! But we'll have some good times, and
+there'll be plenty of work, too!"
+
+"How many cattle you got?" asked Nort.
+
+"About five hundred," Bud answered. "Course you have a share with me,
+that your dad bought, but we don't own 'em outright yet. My dad still
+has a mortgage on 'em."
+
+"But if we have luck we can clear that off; can't we?" asked Dick.
+
+"Sure, this year, maybe," assented Bud. "I never saw steers fatten so
+fast as ours have since I brought 'em to Flume Valley. I reckon the
+land, being without water so long, raises a specially fine kind of
+grass. Of course, there's always some at the far end of the valley,
+good grass, too, but when there wasn't any water for the cattle to
+drink there wasn't any use trying to raise stock there. But now it's
+different."
+
+"And all we want is for the water to stay," added Dick.
+
+"That's all," chimed in his brother.
+
+With Buck Tooth trailing behind, the three boys took the mountain trail
+and reached their camp near the reservoir that evening. They found Old
+Billee and Yellin' Kid waiting for them, these two cowboys having been
+assigned by Mr. Merkel to help his son in the lad's new venture.
+
+"Well, yo' got back, I see," remarked Old Billee as he greeted the
+lads, the Indian going off by himself, for he was rather taciturn in
+his manner.
+
+"Yes, we're here," admitted Bud. "But I can't understand that water
+coming back so unexpectedly."
+
+"Are you sure it stopped running?" asked Yellin' Kid in his usual loud
+voice.
+
+"Sure!" declared Bud. "Didn't Buck see it--or, rather, he didn't see
+it, for there wasn't any water to see coming through the pipe--only a
+few drops."
+
+"I wouldn't take his word," declared Old Billee. "Not that Buck would
+actually lie, but those Indians are queer."
+
+"Oh, we all saw that the water wasn't running," declared Nort.
+
+"Well, it was when I got here," stated the old cowboy. "And there
+wasn't a sign of anything wrong. But if there had been I'd expected
+it, 'count of----"
+
+"That black rabbit, I reckon!" broke in Bud.
+
+"Perzactly!" declared Old Billee. "A black jack shore is bad luck, at
+any stage of the game!"
+
+But for a time there seemed to be no truth in this western omen.
+Following the first mysterious disappearance of the water, and its
+equally strange reappearance, peace seemed to settle down over Flume
+Valley.
+
+The steers and yearlings, with which Bud's father had entrusted him and
+the boy ranchers, thrived and fattened on the succulent grass. Old
+Billee, Yellin' Kid, with Buck Tooth's help, aided the boys in such
+minor duties as were necessary to perform about the camp. The main
+duty was looking after the safety of the cattle, to see that none of
+them strayed beyond the wire fence at the far end of the valley.
+Should any stray from the other egress, nearest Diamond X ranch, no
+great harm would result, as they would still be on their owner's land.
+
+But the farther, or north end, adjoined land owned by Hank Fisher, the
+Double Z representative. And there were ugly stories current
+concerning Mr. Fisher.
+
+But as the days passed, and as the water still flowed through the pipes
+and underground tunnel into the reservoir, Bud and his companions began
+to think they had imagined more troubles than were really to occur.
+
+"Guess that warning was only a bluff," said Bud, one day.
+
+"And the black rabbit doesn't seem to have given you the jinx," added
+Nort.
+
+"But we didn't find that man you shot," put in Dick.
+
+"I don't believe I shot him," declared Bud. "There was blood, sure
+enough, but he may have stumbled, as, in fact, we saw him, and
+scratched himself."
+
+"But where did he disappear to?" asked Nort.
+
+"Give up," answered Bud. "We'll have to take another look after we get
+our first shipment out of the way."
+
+For the first bunch of steers from the Flume Valley camp were to be
+disposed of shortly.
+
+It was the day when this shipment was to be made that Bud, awakening
+early in the tent where he slept with his cousins, uttered an
+exclamation of surprise as he caught sight of something on the blanket
+that covered him.
+
+"What's the matter?" asked Dick, sitting up.
+
+"Did you leave this here?" asked Bud, as he held up a piece of board,
+evidently part of a packing case.
+
+"Me? No!" answered Dick. "What is it?"
+
+"Either it's a joke, or it's the black rabbit getting in his work,"
+answered Bud. "It's from an unknown enemy--another warning!"
+
+And, as Bud held up the board, Nort and Dick could read, scrawled on
+it, evidently with a fire-blackened stick, the words:
+
+"Warning No. 2. When will you quit?"
+
+
+
+
+CHAPTER VI
+
+TROUBLE AT SQUARE M
+
+"Guess that must be a joke," decided Nort, as he stepped gingerly from
+his cot, for it was cold in the mornings, though hot enough at midday.
+"Likely Old Billee or Yellin' Kid stuck it there," added the eastern
+lad, as he looked at the scrawled warning.
+
+"Old Billee wouldn't do it," declared Bud. "He's gotten over his
+joking days. But it might have been Yellin' Kid."
+
+"Sure!" agreed Dick. "Probably he did it to make what Billee said
+about the black rabbit come true--to sort of scare you, Bud."
+
+"Well, of course that _might_ have happened," admitted the western lad,
+but from the tone of his voice, as he made a hasty toilet, his cousins
+could tell he was far from being convinced.
+
+"You don't reckon it could be Buck Tooth, do you?" asked Dick,
+following his cousin's example in attiring himself for the day's work.
+
+"What? That Zuni Indian? I should say not! His idea of a joke would
+make your hair stand on end--or it would in his wild and younger days.
+Now all he cares about, after he gets through riding herd, is to sit in
+the sun and smoke his Mexican cigarettes. Buck Tooth doesn't joke."
+
+"Well, maybe it was Yellin' Kid," suggested Nort.
+
+But when, a little later, they assembled in the meal tent, to partake
+of breakfast, and Bud produced the scrawled board, Yellin' Kid was the
+first to shake his head at the implied question.
+
+"I like fun!" he remarked in his loud, good-natured voice, "but I don't
+play such jokes as this. My idea of fun would be to help dig up
+another one of them queer, slidin'-trombone insects with the three
+horns that the professor fellers discovered. But this--why, Bud, this
+may be serious business!"
+
+"That black rabbit--I told you!" croaked Old Billee.
+
+"Do you really think it means anything?" asked the boy rancher, while
+his young partners in the new venture leaned eagerly forward to listen
+to the answer.
+
+"I sure do," declared Yellin' Kid. "All of us have known, Bud, an'
+your father among 'em, that puttin' a dam in Pocut River, an' taking
+water for you here, at Flume Valley, made the Double Z outfit mad
+enough t' rear up on their hind legs an' howl! Hank Fisher has
+claimed, all along, that th' Diamond X outfit hadn't any right t' take
+water from th' river, t' shunt over on th' other side of Snake
+Mountain, where we are, here."
+
+"Yes, I heard dad say that," spoke Bud. "But if Hank Fisher had any
+rights that we violated, why didn't he go to law about it?"
+
+"That isn't Hank's way," commented Yellin' Kid. "He'd more likely try
+some such tricks as _that_," and the cowboy nodded toward the warning
+on the board.
+
+"Do you think he left that?" asked Nort.
+
+"And was he, or Del Pinzo, in our camp last night?" cried Dick.
+
+"As to that I couldn't say," replied Yellin' Kid. "I slept like two
+tops last night, after I got t' sleep. I didn't even hear you fellows
+_snore_," he added, for the three boy ranchers had a tent to
+themselves, while Old Billee and Yellin' Kid bunked in an adjoining
+one, Buck Tooth having his own special dugout near the camp fire.
+
+"We never snore!" declared Nort.
+
+"Well, I didn't hear a sound!" assented Yellin' Kid.
+
+"Nor I," said Old Billee.
+
+There was no use asking Buck Tooth. An actual demonstration would have
+been required to make him understand what a "snore" was, and then he
+might have misinterpreted it into an attempt to work some "magic" on
+him.
+
+"Well, somebody came in our camp, and left that board--there's no
+getting away from the fact," declared Bud, as he put aside the ominous
+warning. "And it may have some connection with the stoppage of the
+water, or it may not."
+
+"I'm inclined t' think it has," said Yellin' Kid. "An', what's more,
+Bud, I think we'll wake up again, some mornin', t' find that reservoir
+of yours out-a business."
+
+"Do you mean Hank Fisher, or Del Pinzo and his crowd, will blow it up?"
+asked Bud anxiously.
+
+"Not exactly that, but they'll cut off your water supply."
+
+"But how can they?" asked Bud. "They can't do anything to the pipe
+intake at Pocut River without being seen, and dad had legal advice to
+the effect that he has as good right to that river water as Double Z,
+or any other ranch. And as for this end of the pipe here, we can look
+after that, I reckon," and he significantly tapped his .45 which he had
+strapped on, preparatory to getting ready for the cattle shipment.
+
+"That's all right," asserted Yellin' Kid. "But you've forgotten th'
+big tunnel under the mountain, Bud, where the water runs free after it
+leaves the river pipe, an' before it gets to the pipe here."
+
+"But Hank, or Del Pinzo, can't cut off the water inside the mountain
+tunnel without having it back up and run into the river again--and it
+didn't do that!" Bud insisted.
+
+Yellin' Kid shrugged his shoulders, as he started for the corral to get
+his horse, since he was to aid in driving the cattle to the railroad
+stock yard.
+
+"I don't know nothin' about th' scientific end of it," he drawled
+loudly, "but, mark my words, there's some queer business goin' on, an'
+Hank Fisher an' Del Pinzo have a hand in it. Look out for your water
+supply, Bud; that's my advice!"
+
+"An' don't let any more black rabbits cross your path," added Old
+Billee.
+
+"Bunk!" scoffed Bud. "Though I don't like this warning, all the same.
+Let's go take a look at the reservoir, fellows."
+
+But an inspection of the concrete water-container showed nothing wrong
+there. The sparkling fluid, so necessary for the cattle, and so vital
+to Diamond X Second, was spurting from the pipe freely.
+
+"Guess they're only trying to bluff us!" was Dick's opinion.
+
+"Maybe," assented his cousin. "But, all the same, I'd like to know who
+was in our camp last night. If this thing is going to keep up we'll
+have to mount guard."
+
+"That wouldn't be a bad idea," declared Nort. "I don't like to go to
+bed so early, anyhow."
+
+"You'll be glad enough to turn in after we get into the swing of things
+here, branding cattle, shipping 'em off and all that," said Bud. "But
+let's take a look around after we get this bunch off."
+
+And when Yellin' Kid, with another cowboy sent by Mr. Merkel to help
+Bud in getting the steers to the railroad station, had departed with
+the shipment, the boy ranchers, Old Billee and Buck Tooth made a
+careful examination in the vicinity of the tents.
+
+Of course, with so many who really belonged in the camp, tramping
+around it, there was little likelihood of an alien foot being
+discovered. Nevertheless, Bud hoped for something of this sort. But
+it was not to be. No trace of the midnight intruder, who had left the
+ominous warning, was discovered. And yet he had come and gone--had
+even penetrated to the tent where the boys were sleeping.
+
+"It's either bluff, or it means something," declared Bud, as they
+assembled for lunch. "And if it isn't bluff, but a _fight_, Hank
+Fisher and Del Pinzo will find we can stick to our guns as well as
+they!"
+
+"You said it!" cried Nort.
+
+"Del Pinzo didn't stay long in jail; did he?" asked Dick, for,
+following the discovery of the Triceratops and the capture of the
+cattle rustlers, as detailed in the first volume, the Mexican halfbreed
+had been arrested.
+
+"No, he managed to get out, and, by some hook or crook, he still
+manages to escape arrest," Bud answered.
+
+For some time it appeared that the two warnings were only "bluffs." No
+sign came from the unknown, and no trace was seen of Hank Fisher, Del
+Pinzo or any of the unprincipled gang which had made so much trouble
+the previous year for the Diamond X outfit.
+
+Nor did the water coming under Snake Mountain show any signs of giving
+out. Day after day it ran its limpid stream, furnishing drink for man
+and beast, and enabling grass to grow where it had never grown before.
+
+"Some day I'm going to rig up a turbine wheel and attach a dynamo to
+it, so we can have electric light here," declared Bud.
+
+"That'll be great!" exclaimed Dick.
+
+The first shipment of cattle had been safely gotten off from Flume
+Valley, and brought a good price. This money did not all come to the
+boy ranchers, however, as Mr. Merkel had insisted on a strict business
+deal; and he was to be paid for his share of the stock he supplied Bud
+from the first money coming in. Later the boys would get their
+profits--if there were any.
+
+But the first lot of steers had been sent away, bringing a higher price
+than usual because of their prime condition, attributed, so Bud said,
+to the finer quality of grass, and it looked as if the boy ranchers
+might make a success of their first venture.
+
+"Even discounting the black rabbit and the warnings out of the air,"
+said Bud.
+
+It was, then, with somewhat of an ominous feeling that, one morning, as
+the boys and their cowboy friends were at breakfast, they saw a rider
+hastening toward them along the trail that led from Diamond X.
+
+"It's Snake Purdee!" exclaimed Yellin' Kid, when the rider had
+approached near enough to be recognized.
+
+"An' he's ridin' like he had suthin' on his mind!" added Old Billee.
+"I hope that black rabbit----" he murmured, and then his voice trailed
+off into a whisper as Yellin' Kid surreptitiously kicked him under the
+packing-box table.
+
+"Don't scare th' boys!" whispered Yellin' Kid in explanation, as Snake
+Purdee galloped nearer.
+
+The rider flung himself from his pony, which came to a sliding stop
+near the camp tents, and, looking first at the boy ranchers, and then
+at the big, peaceful valley stretching out before him, remarked:
+
+"Yes, there's plenty of room here!"
+
+"For what?" asked Bud.
+
+"More cattle!" answered Snake Purdee. "There's been trouble over at
+Square M, fellows!"
+
+"Trouble?" exclaimed the boy ranchers in chorus. "What kind?"
+
+"Bad trouble," was the reply. "Call your father up on th' 'phone,
+Bud," he added. "He wants t' talk t' you. Yes," he went on, musingly,
+as Bud hastened in to the telephone, "there's bad trouble at Square M!"
+
+
+
+
+CHAPTER VII
+
+DOUBLING UP
+
+Nort and Dick looked at each other as Bud slipped into the tent where
+the telephone had been installed. Snake Purdee strode over to the
+water pail, and took a long drink.
+
+"That's good stuff!" he remarked with a sigh of satisfaction, and then
+he led his pony to the trough, into which the thirsty animal dipped his
+muzzle deeply. "Mighty good water!"
+
+"An' I hope nothing happens to it," voiced Old Billee.
+
+"Happens! What d'yo' mean?" questioned the bearer of bad tidings.
+"The water's here, ain't it?"
+
+"But no tellin' how long it'll run," added the veteran cowpuncher. "A
+black rabbit run across Bud's path the day he was ridin' to meet Nort
+and Dick, and ever since then----"
+
+"Do you mean t' tell me you still believe in that old superstition?"
+laughed Snake Purdee, who had acquired this name because of his
+exceeding fear of rattlers and other reptiles. He had been bitten
+once, he declared, and had nearly died.
+
+"There's more'n superstition!" declared Old Billee. "Look at that!"
+and he brought out the board warning, and related the incident of the
+mysterious disappearance of the water, and its equally strange
+reappearance.
+
+"Oh, it's just one of those freaks of the old, underground river
+course," said Snake. "Of course I wouldn't put much past Hank Fisher
+and Del Pinzo, but if either of them sent these warnings it was t' play
+a joke, an' scare our boy ranchers. Guess Hank's jealous!" laughed
+Snake.
+
+"But what has happened over at Square M?" asked Dick.
+
+"Has Hank or Del Pinzo anything to do with that?" Nort wanted to know.
+
+"I don't see how they could," spoke Snake. "It's just that----"
+
+But at this moment Bud came out of the tent, having finished his
+telephonic talk with his father.
+
+"There's an epidemic of disease at dad's Square M ranch," Bud explained
+to his cousins and the others. "It's so bad that a lot of the steers
+have already died, and dad is going to take off the rest of the stock
+before they catch the trouble. Some he's going to put at Triangle B,
+some at Diamond X and some he's going to haze over to us. We'll have
+to double up, fellows," he told Nort and Dick. "I guess dad is glad
+he's got Flume Valley now. It may save him a lot of money that
+otherwise he'd lose."
+
+"Got t' double up, eh?" murmured Old Billee Dobb. "How many head's he
+goin' t' send here, Bud?"
+
+"About five hundred he told me. They'll be stock that hasn't been near
+the infected cattle," he went on, "so there won't be any danger to our
+herds."
+
+"Can we look after five hundred more steers?" asked Nort.
+
+"Oh, I'm comin' to help you," offered Snake. "I forgot t' say that I
+was going t' move into one of your _flats_," and he waved his hand
+toward where the white tents made an attractive camp. "Didn't bring my
+duffle bag," he added, "but one of th' boys is going t' ride over this
+evening with his 'n' mine."
+
+"Is some one else coming?" Bud wanted to know. "If we double up too
+much we'll need more grub."
+
+"Your dad told me t' tell you he'd send some," went on Snake. "Yep, a
+new ranch hand is due t' arrive this evenin'. He's a wonder with th'
+gun an' rope, t' hear him tell it!" chuckled Snake.
+
+"One of them fly boys?" asked Old Billee, mildly, with a gleam of light
+in his eyes, however. "Will his heels need clippin', Snake?"
+
+"Might," was the brief answer. "But now you know th' worst. There's
+trouble at Square M, an' you'll have to double up with cow punchers an'
+stock, Bud."
+
+"I don't mind," said the boy rancher. "Dad says he'll split the
+profits with me, and that's what we're looking for--to make a success
+of Flume Valley ranch. We'll do it, too!" he asserted confidently.
+
+"If th' water holds out, an' no more black rabbits don't throw you,"
+murmured Old Billee Dobb.
+
+"Shucks!" laughed Bud, but the day was to come when he recalled the old
+cowboy's ominous warning.
+
+"It's queer, though," said Bud that evening, when they were gathered
+around the camp fire, discussing the coming of the cattle from Square
+M, which were to arrive the following day, or the one after that.
+"It's queer what made that disease break out so suddenly among dad's
+steers. There aren't any cases of it at Double Z; are there?" he asked
+Snake. "And Fisher's place is the next one nearest ours."
+
+"No, I don't recall hearin' that Hank's stock is sufferin' any," the
+cowboy admitted. "But Square M is hard hit. It's a disease the
+government experts are tryin' t' find a remedy for. Been experimentin'
+with all sorts of serums, germs an' th' like, I understand."
+
+"Is it a germ disease?" asked Nort.
+
+"That's what they call it," the cowboy asserted. "It can be given
+easy, from one steer to another, just by rubbin' horns, so t' speak.
+Or the trouble may break out sudden in a herd, if th' germ gets loose
+in 'em."
+
+"That's all bosh!" declared Pocut Pete, the new cowboy who had arrived
+just about grub time, with his own outfit and that of Snake Purdee, who
+had ridden over "light."
+
+"What's bosh?" asked Old Billee.
+
+"The idea that this disease is spread by germs, or 'bugs,' as some
+folks call 'em. I think the cattle get poisoned by eating some weed,
+same as lots of 'em get locoed."
+
+"Well, maybe," agreed Bud. "Anyhow, we got good feed here, and plenty
+of water for dad's cattle, as well as ours. We can double up as well
+as not. Now I wonder if we have blankets enough for you two?" and he
+looked at Snake and Pocut, who said his name had been given him as he
+had "punched" cows so long in the vicinity of the Pocut River.
+
+"Oh, we'll make out," asserted Snake, who was easily suited.
+
+But Bud, being the nominal head of the camp, would leave nothing to
+chance. While some of the others were still about the flickering camp
+fire, talking of the trouble at Square M, the strange disappearance of
+the water and kindred topics, the boy rancher went to inspect the tent
+where the older cowboys were to pass the night.
+
+It was fitted with cots enough, and one to spare, but Bud wanted to
+make sure of the blankets. For it gets cold at night on the western
+plains on even very hot days.
+
+As Bud entered the tent he saw, in the dim light of a turned-down
+lantern, a figure sitting on one of the cots.
+
+"That you, Snake?" Bud asked.
+
+"No, it's me," answered the voice of the new cowboy, Pocut Pete.
+
+"Oh," remarked the lad, and as the other arose Bud caught the tinkle of
+glass. For a moment an ugly suspicion entered Bud's mind, but when his
+nostrils did not catch the smell of liquor, which was strictly
+forbidden on all Mr. Merkel's ranches, Bud felt a sense of relief.
+
+Pocut Pete passed out, after Bud had assured himself that there were
+blankets enough, and as the boy rancher was leaving the tent, he trod
+on something that broke, with a grating sound, under his foot.
+
+
+
+
+CHAPTER VIII
+
+DRY AGAIN
+
+"What the mischief's that?" exclaimed Bud, as he unhooked the lantern
+from the tent pole and swung it toward the ground where he had set his
+foot. "Has Nort or Dick lost their bottle of paregoric?" and he
+chuckled as he recalled what use his cousins had made of that
+baby-pacifier when they had been captured at the camp of the
+professors, as related in the book prior to this.
+
+"It _is_ a bottle, and I stepped on it and smashed it," went on Bud, as
+he saw the shining particles of thin glass. "That new cowboy, Pocut
+Pete, must have dropped it. Hope it wasn't any medicine he needed.
+Smells mighty queer, though!" and Bud sniffed the air. "I hope he
+isn't one of those 'dope fiends,'" and again a feeling of apprehension
+passed over him.
+
+Bud picked up one of the largest pieces of the crushed glass bottle.
+The little phial appeared to have been filled with a sticky, yellowish
+substance, and the odor was not pleasant.
+
+"Whew!" exclaimed Bud as he caught a strong whiff of it. "I wouldn't
+want to have to take any of _that_ for medicine. Guess I'll ask Snake
+what he knows of Pocut Pete before I make any inquiries on my own hook.
+And I'll tell him he'd better bury this glass if he doesn't want to cut
+his own feet, or that of the others."
+
+"Bunks all right?" asked Old Billee Dobb, as Bud emerged from the tent.
+
+"All ready to turn in," was the answer.
+
+"Which I'm going to do dark an' early," declared the old cowboy. "I
+have the late watch t'-night."
+
+For it had been decided, with the coming of the additional steers from
+Square M, that it would be necessary to ride herd, as so many cattle in
+a bunch might engender a stampede. And at Old Billee's suggestion the
+night-riding was to start then, to break them in, so to speak.
+
+Bud saw Pocut Pete standing by himself at the cook tent, Buck Tooth
+having been induced to open some cans of peaches, a form of fruit much
+in favor on western ranches where the fresh variety is unobtainable.
+
+"You'd better clean up that glass you left in the bunk tent," Bud
+remarked in a low voice.
+
+"What glass?" sharply demanded the other, and there was in his voice a
+note of defiance, the boy thought.
+
+"The glass bottle you dropped, and I stepped on," Bud resumed, for he
+did not hesitate to give orders in his own camp.
+
+"I didn't drop any bottle!" declared Pocut Pete.
+
+"Well, some one did, and I smashed it," asserted Bud. "If you don't
+want to cut your feet you'd better bury it," and he hurried off to wash
+from his hands some of the unpleasant-smelling mixture that had clung
+to them.
+
+"I sleep with my boots on," said Pocut Pete. "But I'll tell the rest
+of 'em to be careful."
+
+"It would be better," Bud flung back over his shoulder.
+
+It was late next day when cowboys from Square M arrived, slowly driving
+before them the cattle that were to be doubled up with those which Bud,
+Nort and Dick considered specially their own.
+
+"What's the situation over there now?" Bud asked one of the punchers,
+who looked tired and weary, for the trail had been long and dry, as
+evidenced by the eager manner in which the steers rushed for water.
+
+"Pretty bad," was the answer. "This disease, whatever it is, seems to
+kill off mighty quick. I don't know how many your dad has lost, but I
+guess now, what with those we've brought here and them sent to Diamond
+X and Triangle B, that we'll get the best of the trouble. Gosh! You
+got a nice place here!" he added admiringly.
+
+"Yes, it's pretty good," Bud agreed. "Bringing the water over from
+Pocut River made all the difference in the world."
+
+"You got out a lungful that time!" asserted another of the cowboys who
+had helped "haze" over the steers that were transferred to save them
+from infection.
+
+The visiting cowboys departed next day, leaving their animals mingled
+with those in which Bud, Nort and Dick had an interest. The doubled-up
+herd was not too large but what there was plenty of feed and water in
+Flume Valley.
+
+During the days that followed, matters at Diamond X Second, as Bud
+sometimes called his ranch camp, adjusted themselves smoothly. There
+was no further sign, or evidence, of mysterious warnings. The cattle
+throve, and those from Square M, which were not in as good physical
+condition as the animals that had been longer in the green valley,
+began to "pick up" and fatten.
+
+"I tell you what, fellows!" boasted Bud to his cousins, "dad'll be
+wishing he'd kept this ranch for himself! We'll beat him at his own
+game!"
+
+"It would be a big stunt if we could, not taking advantage of his bad
+luck at Square M, though," spoke Nort.
+
+"Well, you have to count on bad luck in this business," remarked Bud.
+"Not that black rabbits have anything to do with it," he laughed, as he
+looked at Old Billee.
+
+Bud and his cousins were returning, one hot afternoon, from having
+ridden to a distant part of the valley, where Snake Purdee had reported
+he had found a calf killed. There was a suspicion that rustlers had
+been at work, but Bud decided the animal had been separated from its
+mother and the main herd, and had been pulled down by coyotes.
+
+"What's that?" asked Nort, when they were within sight of the camp with
+its reservoir in the background.
+
+"What's what?" asked Bud, who pulled his pony aside quickly, to escape
+a prairie dog's burrow.
+
+"Looks like Old Billee waving his hat for us to hit up the pace," spoke
+Dick.
+
+"It is!" asserted Bud, after gazing beneath his hands held in front of
+his eyes as a sun-shield. "I hope nothing's wrong!"
+
+But when they had ridden up, the old cowboy riding out to meet them, it
+was made plain, in a moment, that something had occurred out of the
+ordinary.
+
+Old Billee Dobb was much excited. His eyes blazed and snapped and he
+shook the reins in addition to mildly spurring on his pony.
+
+"More mysterious warnings?" asked Bud.
+
+"Worse'n that," was the answer. "She's dry ag'in!"
+
+"The pipe line?" asked Dick.
+
+"You hit it!" cried the other. "Water's stopped runnin' ag'in, Bud!"
+
+"Whew!" whistled the boy rancher. "And with a double lot of stock on
+hand, too! This _is_ bad!"
+
+
+
+
+CHAPTER IX
+
+A SHOT IN THE NIGHT
+
+Wheeling his pony, Old Billee rode back with the boy ranchers, until
+they reached the bottom of the reservoir wall. Then, dismounting, Bud,
+Nort and Dick scrambled up the earth slope on one side until they could
+look into the storage tank, and at the pipe which, connecting with the
+old underground water-course, kept the reservoir filled.
+
+"She isn't spouting!" said Bud, in blank disappointment.
+
+"Just a dribble," added Nort, mournfully.
+
+"And if it does as it did before that'll stop in a little while,"
+remarked Dick.
+
+"When did it start to stop?" asked Bud, unconscious of the double
+meaning of his words.
+
+"About an hour ago," Old Billee answered. "I happened t' notice it
+when I come up here t' try for a fish."
+
+"Fish!" cried Nort. "Can you get any fish _here_?"
+
+"Sartin sure!" asserted the old cowboy. "They come in from th' river,
+under th' mountain, though how they like the dark I can't say, an' they
+come out of this pipe. I've caught many a good one."
+
+The eastern lads looked to Bud for confirmation, and their cousin,
+nodded, rather gloomily, though.
+
+"Yes," said Bud, "fish do come through the pipe. But if we don't get
+any more water they'll all die off soon."
+
+"Maybe the water will come back--as it did before," asserted Dick.
+
+Bud did not answer. He appeared to be figuring out something on the
+back of an old envelope with the stub of a pencil.
+
+"We'll have enough for a week, I think," finally announced the boy
+rancher. "Then, if the water doesn't come back, we'll have to drive
+all the stock over to Diamond X. Can't take a chance letting 'em die
+of thirst here, even if they didn't stampede, which they'd be sure to
+do."
+
+Two things are vitally necessary on a ranch--grass and water for the
+stock. Of grass there was plenty in Flume Valley, and, had the stream
+continued to come through the pipe, there would have been a goodly
+supply of water, even for the extra stock added from Square M.
+
+But when no fluid spurted from the mouth of the black pipe, the other
+end being hidden in the opening of the natural water course, it spelled
+ruin for Diamond X Second.
+
+"I wonder--I just wonder--if this has anything to do with the threat we
+received?" mused Bud, as he and his cousins went down the slope to the
+little table of land where the tents were pitched.
+
+"Granting that it has, who sent the warning?" asked Nort.
+
+"Who else but the man who doesn't want to see any water diverted from
+Pocut River?" asked Bud, in turn. "I mean Hank Fisher, and the gang he
+trails along with! If anyone stopped this water, he did!"
+
+"But how?" asked Yellin' Kid, who had strolled up to take part in the
+general conversation. "He couldn't do it at th' river end of th' pipe,
+without bein' found out, and he hasn't been around _here_, I'll gamble
+on that--not since we started keepin' watch at night."
+
+"No, he hasn't been here," admitted Bud, slowly. "It sure is a puzzle.
+Well, let's have grub, and talk about it later. It may come back. If
+it doesn't we have enough for a week--maybe longer."
+
+It was drinking water for the cattle that was mostly needed, since the
+occasional, slight rainfall was now sufficient to provide for the
+grass, though some water was used to irrigate certain sections that
+would be called "meadows" in the east. This drinking water was
+conducted to distant troughs by pipes running from the reservoir, the
+pipes being controlled by means of valves, or water gates.
+
+Had there been natural water-holes in Flume Valley it would, long ago,
+have been used as a place to raise cattle. But it was the absence of
+drinking places that caused it to be passed by, until, by artificial
+means, tapping the river through the underground course, Mr. Merkel had
+enabled his son and nephews to become boy ranchers in earnest.
+
+As Bud had stated, there was about a week's supply on reserve in the
+concrete reservoir. When that was exhausted, unless the water again
+started flowing through the pipe, the cattle would suffer from thirst.
+
+"Well, she isn't spouting any," mournfully remarked Nort, as, with his
+brother and Bud, he ascended the slope, standing on the edge of the
+reservoir.
+
+"No," agreed Bud. "She's as dry as an old buffalo skull now. I don't
+know what to do!"
+
+The shadows of dusk were falling, and the boys felt that the night was
+coming with its gloom to match their own feelings. Failure seemed to
+stare them in the face.
+
+"But I don't see how anyone--granting that somebody like Hank Fisher or
+Del Pinzo has it in for us--can shut off the water without operating at
+either end of the flume!" exclaimed Nort.
+
+"That is queer," agreed Bud. "I wonder what's inside that tunnel where
+the old watercourse runs? I've been through it, but couldn't see much
+of anything. I've a good notion----"
+
+He broke off his remarks to gaze intently ahead. There was a movement
+in the gloom, and a figure walked away.
+
+"Who's there?" asked Bud sharply, his hand slipping to his .45.
+
+"It's me," came quickly, if not grammatically, from Pocut Pete, whose
+voice the boys recognized. "I just moseyed up here t' see if she was
+runnin'."
+
+"Well, she isn't," spoke Bud, a bit shortly.
+
+"So I see," came the drawling answer, and it was followed by a faint
+tinkling of glass.
+
+Bud started, and tried to pierce the night shadows. But all he saw was
+the figure of the strange cowboy becoming more and more indistinct.
+Bud was just going to say something when he was halted by the voice of
+Nort.
+
+"I have an idea!" exclaimed the eastern lad.
+
+"What is it?" asked his brother. "Anything to do with this?" and he
+waved toward the reservoir which was strangely still, now that the
+water no longer bubbled into it from the pipe.
+
+"Yes," went on Nort. "Why not investigate and see where the stoppage
+is, Bud?"
+
+"Investigate what?"
+
+"The pipe line--the old underground water-course."
+
+"You mean go through the tunnel?" Bud asked.
+
+"Sure! Why not? You say it's big enough all the way through, and the
+water itself doesn't occupy much of the bottom. We could walk it in a
+day, easy!"
+
+"Yes," agreed Bud, "it isn't more than five miles, though we'd have to
+carry lanterns, and we might get lost in some side passage."
+
+"That's just what I want to find out about!" cried Nort. "If there
+_is_ a branch passage maybe that's where the water goes! Come on, Bud,
+let's go through the tunnel!"
+
+"I'm with you!" said Dick.
+
+For a moment Bud hesitated and then, as he was about to reply, there
+came the sudden sound of a shot, which shattered the night with a
+sliver of flame, plainly visible to the boys.
+
+Instantly a band of coyotes set up their weird howling, and the
+startled steers lowed and bellowed as they rushed about.
+
+
+
+
+CHAPTER X
+
+INTO THE TUNNEL
+
+"What's that?" cried Bud.
+
+"Who's there?" demanded Nort.
+
+The hand of Dick went toward the .45 he wore in a holster at his belt,
+and, it might be added, the hands of the others did also.
+
+"Keep your shirts on," came the somewhat drawling voice of Pocut Pete,
+who, it seemed, had returned after shuffling off in the darkness. "I
+just winged a coyote."
+
+"Oh," murmured Bud. "You were shooting at them, were you?" he asked.
+
+"Not exactly," answered Pocut Pete, as he sauntered up out of the
+gloom. "I saw something movin' down among th' cattle, an' I knew it
+couldn't be any of you fellows, so I let go at him."
+
+"_Him!_" cried Nort. "Was it a man?"
+
+"Looked like one," drawled Pete. "I heard you'd had trouble with
+rustlers before I came, so I wasn't takin' any chances. I didn't aim
+t' hit him, though, only t' scare him, an' I must have winged one of
+them night-owls!" He chuckled at this characterization of the coyotes.
+
+"Let's take a look down there," suggested Bud to his cousins, their
+worried interest in the stoppage of the water momentarily eclipsed by
+the new excitement.
+
+"Oh, you won't find anyone down there _now_!" Pocut Pete made haste to
+say. "If it was a rustler he's far enough off by _this_ time, an' I'm
+not positive I really saw one--it was so dark."
+
+"It won't do any harm to take a look," declared Bud, and his cousins
+were of the same opinion.
+
+"Suit yourself," spoke Pete, easily. "If I did hit him let me know."
+
+Again he moved off in the darkness, and the boy ranchers, after a
+moment of hesitation, started in the direction whence the shot had been
+heard and the sliver of flame seen. Pocut Pete had gone on the
+opposite trail after returning to the boys, a fact which caused Dick to
+remark:
+
+"Wouldn't you think he'd want to see if he did wing anybody?"
+
+"He knows well enough he didn't," declared Bud in a low voice, for he
+and the others realized that sounds, especially voices, carried almost
+as clearly in the night air as across a body of water.
+
+"What made him talk that way then?" asked Nort.
+
+"Oh, he's--queer, I guess," replied Bud. "I don't exactly just like
+the way he acts. Did you fellows hear the tinkle of glass just before
+that shot?"
+
+"I did," answered Nort, but Dick was not so sure. "What do you make of
+it?" Nort wanted to know.
+
+"Wish I knew," spoke Bud, and then he told them about having found the
+small, thin, broken phial of dubious-smelling mixture in the bunk tent
+of the older cowboys.
+
+"Do you think he takes 'dope,' or medicine of some sort?" asked Dick.
+
+"It's hard to say," was Bud's reply. "But let's look around and see
+what we can find."
+
+Their search was unrewarded, however. The cattle quieted down after
+the shot, and the coyotes only occasionally gave vent to their
+blood-curdling yells. But as for finding anyone who had been
+shot--including even a miserable coyote--there was not a sign.
+
+"Guess Pete didn't wing anybody after all," mused Dick, as he and his
+chums turned back toward the camp.
+
+"I never s'posed he did," grunted Bud. "He's a four-flusher, that
+fellow is, in my opinion. I wish dad had sent me somebody else."
+
+"He's a good cowboy," defended Nort.
+
+"Yes, but I don't feel that I can trust him. I'd rather have one like
+Old Billee, slow as he is, than two Pocut Pete chaps," grumbled the boy
+rancher. "But we've got other worries besides him, fellows! What are
+we going to do for water, now that we have a double supply of cattle at
+our ranch? That's what's worrying me!"
+
+"It's enough to worry anyone," Dick agreed. "Maybe the water will come
+back, Bud."
+
+"I hope it does," added Nort.
+
+"We'll take a stroll through that tunnel--it's the only way to find out
+what's wrong," decided Bud. "Talk about black rabbits! I begin to
+think Old Billee was more right than wrong!"
+
+"But your bad luck, so far, isn't as bad as your father's in losing
+cattle from disease," remarked Nort.
+
+"No, and I hope that the epidemic doesn't break out here at Diamond X
+Second," went on Bud. "If it starts, and we don't get the water back,
+we may as well give up!"
+
+He was plainly discouraged, and no wonder. He was young, and it was
+his first experience as a rancher "on his own." Nort and Dick, too,
+were a little down-hearted.
+
+"But maybe things will look better to-morrow," suggested Nort, as they
+turned in for the night, having discovered nothing alarming in the
+direction where Pocut Pete had shot.
+
+"Maybe," half-heartedly assented Bud.
+
+But there was no water coming through the reservoir end of the tunnel
+pipe when the sun shone again, and, after breakfast, the boy ranchers
+prepared to explore the dark cave-like opening which extended under the
+mountain.
+
+"I hope we can turn it on," said Bud, and he looked at the concrete
+basin of water, trying to calculate how much longer it would last if
+the supply were not replenished. Already it was lower than it had been
+the night before, for the cattle had drunk freely during the darkness.
+
+Lanterns were gotten ready, a supply of grub packed, weapons were
+looked to (for who knew what beast might not lurk in the tunnel?) and
+at last the boy ranchers were ready to start.
+
+"Good luck!" wished Yellin' Kid as the little party started for the
+mouth of the tunnel.
+
+"Thanks," chorused Nort, Dick and Bud.
+
+Then they entered the black opening.
+
+If you will imagine a hillside, with a hole, or tunnel, about ten feet
+high and as broad, but of irregular shape, opening into it, and on the
+bottom, or floor, a two-foot iron pipe out of which, at normal times,
+ran a stream of water, you will have a good idea of the place into
+which our young heroes were to enter.
+
+The tunnel extended all the way through Snake Mountain, curving this
+way and that, as a brook curves its way through a meadow. In fact the
+tunnel had been made, centuries ago, by a stream forcing its way
+through the soft parts of the mountain, and it was this old, hidden,
+underground stream-way of which Mr. Merkel had taken advantage to bring
+water to Flume Valley.
+
+The stream flowed along the bottom of the tunnel course, leaving room
+on either side for persons to walk, as they might walk along the banks
+of a stream in the open. The underground river was not more than four
+feet wide, and about the same in average depth, but in places it flowed
+with a very powerful current.
+
+"Whew! It's black as tar here!" exclaimed Dick, as they walked in past
+the pipe, and found themselves in the tunnel proper.
+
+"As bad as the Hole of Calcutta," added Nort, who had read that grim
+story of the Sepoy rebellion in India.
+
+"Do you want to back out?" asked Bud, swinging his lantern so that it
+cast flickering shadows on the place where water had flowed, but where
+there was none now.
+
+"Back out!" cried Nort. "I should say not! Lead on, Macduff!"
+
+And they started off in the blackness of the tunnel, with only the
+faint gleams of the lanterns to illuminate their way. What would they
+find?
+
+
+
+
+CHAPTER XI
+
+THE RUSH OF WATERS
+
+Echoes of the footsteps of the boy ranchers sounded and resounded as
+they tramped along the now dry water-course of what had, only a day
+before, been a life-giving stream of water. The rocky and
+roughly-vaulted roof overhead gave back the noises like the soundbox of
+a phonograph, and the lads had to speak loudly, in places, to make
+their voices carry above the echoes. These places were spots where the
+vaulted roof of the tunnel was higher than usual.
+
+They had walked on, the semi-circular spot of light at the entrance
+near the black pipe growing more and more faint, until it was not at
+all visible.
+
+"There she goes!" exclaimed Dick, looking back.
+
+"What?" asked his brother.
+
+"The last gleam of daylight," was the answer. "If anything happens to
+our lanterns, so that they go out, and we get mixed up in some branch
+passages--good night! That's all I have to say!" and Dick was very
+emphatic in this.
+
+"By Zip Foster!" exclaimed Bud, using that expression for the first
+time in several days. "You're a cheerful chap to have along on a
+picnic like this, Dick! Not!"
+
+"Well, might as well prepare for the worst and hope for the best,"
+laughed Dick, while Nort inquired:
+
+"Why don't you tell us more about Zip Foster?"
+
+"Oh--you--say, did you hear anything then?" asked Bud, and his voice
+had in it such a note of anxiety that his companions did not, at the
+time, imagine he might have been putting them off from a much-wanted
+and often-delayed explanation of this mysterious Zip Foster personage.
+
+"Hear what!" asked Dick.
+
+"Something like water running," replied Bud. "I have a notion that our
+stream--I call it ours for it doesn't seem to belong to anyone
+else--our stream may just trickle off, now and then, into some other
+underground course."
+
+"Maybe it does," agreed Dick. "But I don't hear any water running."
+
+"Nor I," added his brother.
+
+"Maybe I was mistaken," Bud admitted. "But I sure would like to come
+across that missing water of mine!"
+
+He little realized, nor did the others, what fruit his wish was to
+bear, and that very shortly.
+
+"I guess what you heard was the echoes," spoke Dick. "I never heard so
+many queer noises."
+
+"It's like the cave of the winds," murmured Nort. "But it's a great
+adventure all the same, Bud! I mean it would be great if we didn't
+have to worry about the water not coming back," he made haste to add,
+for he realized what it would mean to their new ranch in Flume Valley
+if no drink could be had for the cattle.
+
+"It beats the finding of the Triceratops all to slathers!" exclaimed
+Dick, "and that was no slouch of a happening, either."
+
+"Yes, no telling what's ahead of us," spoke Bud, as he walked along,
+unsteadily enough for the way was rough and filled with stones. And,
+as the boys tramped along in the tunnel, part of the time in the very
+bed of the stream that had gone dry, their lanterns cast fantastic
+shadows on the rocky walls. I have said that the stream was dry, but
+this was not strictly true, for in places, where the uneven bed formed
+depressions, there were pools of water. And, in some places, there
+were even little rills trickling along. But they never would reach the
+iron pipe that discharged into the reservoir.
+
+On and on tramped the boys, pausing, now and then, to hold up their
+lanterns and inspect the rocky walls of the underground tunnel which
+echoed so strangely to their footsteps, and through which swept
+strange, cold and clammy winds.
+
+"Well, I reckon we'll have to go all the way to the end before we
+discover anything, if we do find it," said Bud, when they had walked on
+for over an hour. Their pace was slow because of the uneven footing.
+
+"And when we get to the other end and find the water running into the
+pipe at the dam in Pocut River, what then?" asked Nort.
+
+"We'll hardly find that, I think," said Bud. "Or, I mean, we won't
+have to go all the way to the other end if the water is found running
+there."
+
+"Why not?" asked Dick.
+
+"Because, if the water's running in from the dam end of the pipe, we'll
+meet the stream before we get all the way through the tunnel," Bud
+explained. "I meant to call up on the telephone and find out if
+everything was all right at the river end before we started out, but I
+forgot. My theory is that the stream gets into this tunnel from the
+river all right, but is shunted off before it reaches us," he added.
+
+"How shunted?" Dick wanted to know.
+
+"That's what I can't tell," spoke Bud. "But why try to puzzle this out
+until we get something better to work on? I'm hungry! What do you say
+that we eat?"
+
+"Suits me," agreed Nort.
+
+"I'm not going to vote in the negative," asserted Dick.
+
+They judged that they were about a quarter way through the mysterious
+tunnel now, and, setting down the lanterns on the rocky floor, the boy
+ranchers took out the food they had brought with them. It would be
+risky to kindle a fire in that enclosed place, Bud decided, as the
+smoke might choke them, though so far they had found an abundance of
+fresh air, a current blowing part of the time in their faces, and part
+of the time in the opposite direction. This proved that there was a
+good draft in the elongated cave, but it was voted best not to take any
+chances, though there was plenty of dried driftwood on the tunnel
+floor, and this could have been used for a blaze.
+
+But the boys sat about in the gleam of their lanterns, and, while they
+ate the sandwiches they had brought, they talked of the strange
+happenings that had led up to this venture in which they were now
+joined.
+
+Suddenly Bud, who had just taken up a piece of fruit cake, part of a
+chunk that his pretty sister Nell had sent over from the main ranch
+house a day or so before, stopped chewing in order to listen better;
+for, as you doubtless know, the action of the jaws precludes keen
+attention to outside sounds.
+
+"What's the matter?" asked Dick, noting his cousin's act.
+
+"I heard something," Bud answered.
+
+"I'm hearing things all the while!" declared Dick. "This is the most
+weird place for mysterious noises I ever struck!"
+
+"But this is different," insisted Bud. "Listen!"
+
+Nort and Dick stopped chewing and strained their ears to catch the
+sound that had attracted Bud's attention. A strange, rushing,
+whispering echo seemed to fill the tunnel.
+
+"Doesn't that sound like rushing water?" asked Bud.
+
+"Yes," agreed Dick, after a moment of intentness; "it does."
+
+"Look out!" quickly yelled Nort. "It _is_ water, and on the rush, too!
+Jump for your lives! It's a flood!" and making a grab for one of the
+lanterns, that they might not be left in total blackness, he sprang
+toward the rocky side of the tunnel, an example followed by his
+companions.
+
+And the rush of waters filled the underground cave with a mighty,
+roaring sound.
+
+
+
+
+CHAPTER XII
+
+THE RISING FLOOD
+
+Stumbling, slipping, sliding, half-falling, bruising themselves on the
+sharp rocks, but ever leaping forward toward the sides of the tunnel,
+and away from the depressed centre down which they could see the rush
+of waters coming, the boy ranchers at last managed to reach the granite
+wall. Nort had succeeded in grabbing up one of the lanterns, but there
+was no time for Dick or Bud to take one, and the food had to be
+abandoned.
+
+"Climb up! Climb up, if there's a ledge!" shouted Bud. "We'll be
+drowned if we can't get above the water!"
+
+He had, somehow or other, brought up in the rear. Though he did not
+admit it, this was because he had shoved his cousins ahead of him,
+hoping thus to enable them to gain a safe place.
+
+And as Nort and Dick glanced back they saw, in the gleam of the one
+lantern left alight, a white mass of water bearing down on them, and,
+seemingly, filling the tunnel from wall to wall, as it rushed foaming
+and murmuring onward.
+
+It was as though a dam had suddenly burst, or some obstruction had been
+removed, allowing the pent-up waters to rush along the accustomed
+channel. And if you have ever noticed a dammed-up stream, say in some
+gutter, thus quickly released, you can imagine what happened on a
+larger scale in the tunnel where the boys were.
+
+The water, normally, flowed only in the four-foot channel. But now it
+spread out on either side, and, of course, was much deeper in the
+centre. But as the tunnel sloped from either wall, in a sort of V
+shape to the centre channel, naturally the parts nearest the side walls
+were less covered by water than the others.
+
+It was because of this that Bud, Nort and Dick were enabled to maintain
+a footing, though they were knee-deep in water in an instant, and the
+one remaining lantern had to be held up to prevent it from being
+engulfed and extinguished in the sudden flood.
+
+"Climb up! Climb up!" shouted Bud. "Isn't there some place--some
+rocky ledge--where you can find a footing? The water's getting deeper!"
+
+And this was true. Either the flood was growing at its source (a place
+as yet unknown to the boys) or it was running too rapidly, and in too
+great a volume, to accommodate itself to the tunnel channel, and was
+thus piling up in the vicinity of the boys.
+
+"What happened? What caused it?" cried Nort.
+
+"Never mind that--now!" shouted Bud. "Find the highest place you can,
+and stick!"
+
+"Suppose the whole tunnel fills?" asked Dick, trying to pierce the
+semi-gloom, and look for a refuge on the rocky wall.
+
+"If it does we'll have to swim for it," grimly said Bud. "But isn't
+there some place where you can climb up?"
+
+"This looks like a ledge," Dick answered, as he caught sight of a
+darker shadow on the rocky wall of the tunnel, above his head, when his
+brother swung the lantern.
+
+"Just what we need!" exclaimed Bud, as he waded through the
+ever-deepening water to the side of his cousins. "Up with you! Here,
+Nort, I'll hold the lantern until you make it!"
+
+Thus, again, Bud was seeing that his cousins reached a place of
+comparative safety before he looked to himself. For they found the
+ledge, once they had scrambled up to it, well above the water, and wide
+enough to give shelter and a safe perch for all three.
+
+"Whew! That was touch and go!" murmured Bud, as he leaned back, half
+exhausted, against the rocky wall at the rear of the ledge.
+
+"I should say so!" gasped Dick. "It all happened so suddenly that I
+don't know yet what it was all about."
+
+"The stream suddenly started flowing again," spoke Bud. "That's all
+there was to it. Must have been dammed up some place, and suddenly
+released. It's still rising, too," he added, as he leaned forward and
+held the lantern down over the ledge where he and his cousins had taken
+refuge.
+
+"Rising?" sharply inquired Nort, and there was a tone of anxiety in his
+voice.
+
+"Yes," remarked Bud, as he swung the lantern to and fro. "We didn't
+get up here any too soon, fellows! Look, the water would be up to our
+waists down there now, in the most shallow place, and it's got speed
+like one of Christy Mathewson's curves!"
+
+His cousins could see that he had not exaggerated the matter. The
+waters were rising. Inch by inch, and foot by foot, the flood was
+approaching the crest. Where the boy ranchers had sat in the almost
+dry bed of the stream, to eat their lunch, there was now a mad race of
+swirling waters. Where they had stood, before climbing up to the ledge
+of safety, there was now three feet depth of water. And, as Bud had
+said, it was flowing along so swiftly, like the stream which turns a
+mill-wheel, that the boys could hardly have been able to keep their
+feet had they been down in the current, or even on the weakest edge of
+it.
+
+But, as they were, they were safe for the time being. How long that
+would be the case none could tell. They could see, in the gleam of the
+one lantern saved in the mad rush, that the stream was coursing along
+as it had never coursed before.
+
+"There must be a powerful lot of water coming out of the reservoir
+pipe," Nort remarked.
+
+"Biggest ever, with all this water behind forcing it out," agreed Bud.
+"I hope the pipe holds."
+
+"It isn't as if the pipe were the only outlet," said Dick. "You know
+the water can flow out of the tunnel above, and on either side of the
+conduit."
+
+"Yes," agreed Bud, "and dad had it put in that way on purpose, so if
+ever a big flood did come, the tunnel could relieve itself without
+ripping away the pipe and reservoir. There's a sort of spillway at one
+side of the reservoir, you know."
+
+The boys from the east had noticed this. Up to now no water had run
+off through this auxiliary channel, but it was there for emergencies
+such as now had occurred. And the water could find a vent and outlet
+down the middle of Flume Valley, as, indeed, the surplus from the
+reservoir itself did, when there was any.
+
+"Well, it sure is queer, and we had a mighty narrow escape," remarked
+Nort, as Bud leaned back again with the lantern. "But the fellows back
+at the camp will be scared."
+
+"I reckon they will," admitted Bud. "They'll see the water spouting
+out, in a greater volume than ever before, and they'll imagine all
+sorts of things have happened to us."
+
+"Well, nothing has happened yet--except we've lost two perfectly good
+lanterns, and what grub we didn't eat," asserted Nort.
+
+"But something else may happen," said Bud in a low voice, as, once
+more, he leaned forward, and again held the lantern over the edge of
+the rocky ledge.
+
+"What?" Dick wanted to know.
+
+"Look," was what Bud replied. And his cousins, glancing down, saw that
+the waters were rising, rising, rising!
+
+When would they stop?
+
+
+
+
+CHAPTER XIII
+
+WHERE DID IT GO?
+
+Pressing back toward the rocky ledge, against which they leaned, gazing
+with fearsome eyes at the rising waters, on which the lantern-light
+shone fitfully, and almost holding their breaths at times, so great was
+the strain, the boy ranchers waited--for what they scarcely knew. And
+yet they did, in a measure.
+
+For they waited to see if the waters would stop rising, a happening, as
+they well knew, which, alone, could save their lives.
+
+As one of them had remarked, they might have to swim for it. But,
+looking at the foaming current, dashing along over jagged rocks on
+which the boys had more than once stumbled, they knew what a risk that
+effort to escape would bring.
+
+And should the water fill the whole tunnel they would have no earthly
+chance!
+
+For only a fish can exist in a hose or pipe completely filled with
+water, and that is what the tunnel would become if the water rose to
+the roof--merely a great, underground rocky pipe for the conveying of
+the liquid from Pocut River.
+
+So you can easily imagine with what anxiety Bud, Nort and Dick watched
+the rising water. Every now and again one of them would lean over the
+ledge, swinging the lantern to and fro, so its gleams would be
+reflected in the hurrying, foaming stream, and indicate how fast it was
+rising.
+
+At first the rate of rise had been rapid. But as the boys, again and
+again, made observations in the semi-gloom Bud, at length, uttered a
+joyful cry.
+
+"Look!" he shouted, pointing with trembling finger at the foamy flood
+close, now, to the top of the ledge. "Look!"
+
+"What--a big fish?" asked Dick.
+
+"Fish nothing!" retorted his cousin. "But the water is going down!
+Look, it isn't as high as it was. I can see a wet mark where it came
+up to, and it's two inches below that now! The flood is going down!"
+
+"Are you sure?" asked Nort, eagerly.
+
+"Look for yourselves!" invited Bud, handing over the lantern.
+
+Nort's observation was confirmatory of his cousin's.
+
+"She _is_ going down!" remarked Nort. "And just in time, too!"
+
+How truly he spoke was evidenced by that fact that another inch of rise
+would have sent the flood over the ledge on which the boys rested!
+
+So narrow had been their escape!
+
+"If she only doesn't begin to rise again, after she starts going
+down--as you say she is--we'll be all right," said Dick. "But if she
+comes up----"
+
+He did not finish what he started to say, but his companions knew what
+he meant, and they looked each other in the face with grave
+apprehensions.
+
+"The question is now," went on Bud, as he again took an observation and
+noted that the flood was still on the descent, "how long we shall have
+to stay here."
+
+"If it's too long we'll be wanting some of that grub which was washed
+away," asserted Diet. "In fact I dropped a sandwich half eaten."
+
+"Same here," remarked his brother. "But let's hope that it will go
+down as suddenly as it came up."
+
+That was all they could do--hope; but it bore fruits, for in about an
+hour, as they ascertained by glances at their watches, the flood was
+almost down to the normal channel of the underground stream.
+
+"And if it will only stay there we can venture to keep on to the other
+end of the tunnel," spoke Bud.
+
+"Will you do that?" Dick wanted to know.
+
+"Why not?" asked Bud. "We want to see what happened, and where this
+water goes to when it disappears so suddenly; don't we?"
+
+"Yes," agreed Dick. "But I thought, after our escape, that we had
+better head back for camp."
+
+"It's about six of one and half a dozen of the other," asserted Bud.
+"We're almost half way through the tunnel, now, and we might as well
+keep on. I'd like to solve this mystery, and we can't if we call it
+off now."
+
+"That's right," assented Nort. "We don't run any more danger going on
+to the river end of the tunnel than we would in going back to the camp
+end. That is unless we discover a big cavern, or hole through to
+China, in the other end of the tunnel. Even then we might be able to
+skirt around it."
+
+"Let's go on!" suggested Bud, as he prepared to climb down off the
+ledge. "This thing has my goat!"
+
+"Speaking of goats is most appropriate on a cattle ranch," laughed
+Nort, and the spirits of all the lads were lighter now. "But let's
+keep on to the end for which we started!"
+
+This was agreed to and, after waiting a little while to make sure that
+the waters were not again going to rise, away started the boy ranchers.
+They were traveling lighter now, for they only had one lantern, and no
+food to carry.
+
+The remainder of the tunnel was as the first part had been--a great,
+uneven tube through the mountain, twisting and turning here and there,
+sometimes the roof being so high that it did not show in the swinging
+lantern-light, and again being low enough, almost, for the boys to
+touch.
+
+On all sides was evidence that the flood had been here, as it had been
+at the place where the boys took refuge. Now and then they came to
+deep pools, which they had to skirt, and, in one case, leap over.
+
+Suddenly, as they were walking along, the lantern which Bud was
+carrying went out, leaving them in pitch blackness!
+
+"Hello! What's the idea?" asked Nort.
+
+"Did you do it on purpose?" asked Dick.
+
+"Why, no, of course not!" asserted Bud. "The oil must be gone, though
+I filled it before we started, and it ought to have burned longer than
+this."
+
+"Whew! This is tough!" bemoaned Nort. "Left in the dark!"
+
+"Not altogether!" exclaimed Bud. "I brought some candles!"
+
+"Great!" voiced Nort. "Light up!"
+
+Which Bud did, placing a short length of candle inside the lantern, by
+fastening it, with some grease that hardened, on top of the oil
+reservoir of the wick.
+
+"But I can't understand what happened to the lantern," went on Bud,
+making an examination by means of a second candle, from the store he
+had, luckily, placed in his pocket. "Oh, yes, I can!" he went on.
+
+"What?" asked Dick.
+
+"One of the soldered seams of the lantern oil tank started, and the oil
+has leaked out. Guess one of us must have banged it against a stone
+when we made the rush. But we'll be all right. A candle in the
+lantern is nearly as good as the regular wick."
+
+It was not quite so good, but the boys made the best of it as they
+tramped on through the tunnel, hoping to reach the river end without
+another flood, or any mishap.
+
+"The water seems to be behaving very nicely," observed Nort, as they
+all saw that the stream was well within its rocky channel.
+
+"But what gets me," said Bud, "is where it goes to--when it goes. I
+mean where does it disappear to? We haven't come to a single branch
+tunnel, or any other passage that could drain off the river water."
+
+"That's right," agreed his cousins.
+
+"But maybe we'll find it further on," suggested Nort.
+
+"We'll soon know, for we must be close to the other end now," observed
+Bud. "Our candles are holding out well."
+
+They had come several miles, as they knew by the time consumed. The
+way through the tunnel had been uphill all the way, as it must needs be
+to allow the water to run down to the reservoir in Flume Valley. But,
+so far, they had seen nothing to indicate any side channel for the
+stream--any place that might drain off the water, and return it in such
+a sudden volume as to cause a flood.
+
+"I can't understand it," Bud remarked as he swung the lantern to and
+fro. "It sure is a puzzle. Where does the water disappear?"
+
+His cousins could offer no solution. All the way along they had
+carefully scanned the underground stream, but there appeared no break
+in its uneven, rocky bank in the middle of the tunnel.
+
+"Well, let's keep on," suggested Nort. "We aren't at the end yet, and
+it may be close to the intake--I mean the mysterious influence--that
+shuts off our water supply and turns it on again, may be there.
+Forward, march!" he cried gaily.
+
+Together they started off, having come to a momentary halt to inspect a
+place wider and deeper than usual, when Bud suddenly came to a stop and
+exclaimed:
+
+"Some one is coming!"
+
+
+
+
+CHAPTER XIV
+
+A NIGHT ATTACK
+
+Instantly the boy ranchers came to a halt, standing there in the
+tunnel, beside the running water. They had nearly reached the other
+end of the flume, and could dimly see, ahead of them, a faint glow,
+which told of daylight to come. Bud, who was carrying the lantern,
+made shift to hide it behind the bodies of himself and his cousins, so
+that the unknown, approaching, might not have them at a disadvantage,
+he being in the dark.
+
+"Who you reckon it is?" asked Nort. He and his brother were rapidly
+falling into the custom of using the picturesque if not always elegant
+talk of the west. Nort spoke in a whisper, and Bud answered in the
+same tone.
+
+"Can't imagine who it may be," spoke the western lad, "but if it's
+Hank, Del Pinzo, or any of their gang----"
+
+He did not finish, but a slight movement told that he was freeing his
+.45 in its holster, an example quickly followed by Nort and Dick.
+
+Meanwhile the steps continued to approach, echoing loudly in the
+vaulted tunnel, as if the maker of them had no design to conceal his
+movements. In another few seconds the boys saw, looming in front of
+them, as displayed by the gleam of their half-hidden lantern, a bulky
+figure. At the same moment the figure seemed to become aware of the
+presence in the tunnel of others besides himself.
+
+"Who's there?" came in sharp challenge.
+
+And what a relief it was to the boy ranchers when they heard that voice.
+
+"Slim!" cried Bud. "Slim Degnan!"
+
+"That you, Bud?" called the foreman of Diamond X ranch, as he
+recognized the voice of his employer's son, while Bud, in turn, sensed
+whom the looming figure was.
+
+"Sure!" Bud joyously answered. "And Nort and Dick are here! Say,
+what's the matter with our water? Is there a stoppage at the dam?"
+
+"Nary a stop, but your dad got a telephone from your side-partners at
+the valley camp, saying you'd started through the tunnel to see what
+caused the shut-off. I happened to be over near Square M, seeing if I
+could get on the track of that cattle epidemic, and they relayed your
+dad's message on to me. So I hit the trail for here."
+
+"What was dad's message?" Bud wanted to know.
+
+"Why, he said you, and them tenderfeet---- No, I'll take _that_ back!"
+Slim hastened to say as he recalled all that Nort and Dick had done.
+"Anyhow, he said they shouldn't have allowed you to come in the tunnel
+alone, and he asked some of the men, from this end, to go in and see if
+they could locate you."
+
+"You found us," said Bud.
+
+"Well," resumed Slim, "I just got here, heard the news and I started
+in. Some of the others are coming, but I guess we don't need to make
+any search. You're here!"
+
+"And more by good luck than good management," asserted Dick.
+
+"How's that?" asked Slim, as they all started for the opening at the
+river end of the tunnel, where daylight dimly showed.
+
+"Why, when we started in at the other side the stream was dry,"
+explained Bud. "There wasn't a drop coming through the pipe into the
+reservoir, and we left, early this morning, to see what the trouble
+was. When we got half way through the stream suddenly began flowing,
+and there was a regular flood. Only that we found a ledge to climb up
+on, we'd been drowned!"
+
+"As bad as that!" gasped Slim.
+
+"Every bit!" Dick asserted.
+
+"But tell me," went on Bud, "did the water stop at the river end, Slim?
+Was there any stoppage at the dam or pipe?"
+
+"Nary a stop, Bud," Slim answered. "They told me, when I started in,
+that the water had been flowing all night, as usual, and they didn't
+see why you claimed there was none at your end."
+
+"By Zip Foster! But there's something mighty strange here!" cried the
+boy rancher.
+
+"You intimated good and plenty that time!" declared Slim as he and the
+boys reached the river end of the tunnel, where the intake pipe took
+the water from the Pocut stream, delivering it to the tunnel.
+
+"But here's a queer part of it," went on Dick, as they joined the other
+cowboys who were preparing to follow Slim in, and search for the
+Diamond X lads. "No such body of water, as so nearly overwhelmed us,
+ever came through this pipe," and he pointed to the one that tapped the
+dammed-up water of the river.
+
+"That's right!" agreed Bud. "This thing gets worse and worse! We'll
+never get to the bottom of this mystery!"
+
+"You're right!" declared one of the cowboys. "When you're dealing with
+them underground water-courses you never know what you're up against.
+The old Indians and Spaniards who lived here hundreds of years ago had
+their own troubles, and maybe they wished them same troubles on to you."
+
+"What you mean?" asked Slim. "That's all bosh!"
+
+"Bosh nothin'!" declared another. "You read history an' you'll get
+lots of cases where streams showed up, and then vanished under
+mountains, more than once."
+
+"A heap sight you know about _hist'ry_!" laughed Slim in good-natured
+raillery.
+
+"Well, this is sure queer, anyhow!" declared Bud. "Is there any
+history of the stream that waters our valley?" he asked the cowboy who
+had made the assertion.
+
+"Not your particular one," was the answer, "but there's lots of just
+such cases mentioned--hidden water-courses and all that."
+
+"Well, there's something wrong," agreed Bud, "and I believe there must
+be some place along the tunnel where our water shunts itself off at
+times, and turns itself on again. We were looking for just such a
+place."
+
+"And you didn't find it?" asked Slim.
+
+"Nary a find!" asserted Bud.
+
+"But we aren't going to give up, just on that account!" said Nort.
+
+"Bet you not!" added his brother. "We'll try it again, and take a
+canoe with us, so if the dry water-course suddenly turns wet, we can
+paddle along it."
+
+"Well, it seems to be all right now," spoke Slim. "And you'd better
+'phone your father that you're all right, Bud. He'll be anxious to
+hear."
+
+And after Mr. Merkel had been assured, over the wire, of the safe
+transit of his son and nephews through the tunnel, the boys' camp was
+called up, to let Old Billee and the others know that no accident had
+happened.
+
+"Gosh! I'm glad to hear that!" said the veteran cowboy over the wire.
+"When we see that there water come gushin' out, we thought sure you was
+goners, Bud!"
+
+"Then the water is running again?" Bud asked.
+
+"Absolutely!" declared Billee. "You comin' back here?"
+
+"Sure! But _over_ the mountain--not _under_ it."
+
+Bud and his boy rancher chums remained that night at the store
+settlement near the dam, getting beds in what passed for a hotel. It
+was too late to secure horses and ride over Snake Mountain trail back
+to Flume Valley.
+
+While thus having a night of leisure, and seeing such sights as were to
+be viewed in the little town, Bud and his chums discussed the queer
+situation of the mysteriously disappearing and reappearing water. But,
+talk as they did, and venture opinions as they and their cowboy friends
+did, no one could hit on a solution.
+
+"We'll just have to make another and more careful inspection," declared
+Nort.
+
+"That's what!" agreed Bud.
+
+They learned from Slim that the situation regarding the cattle epidemic
+at Square M ranch was not much better. All stock which had not been
+exposed to the infection had been removed, either to Diamond X,
+Triangle B or Flume Valley, and the infected steers remaining there
+were being treated by a veterinarian whom Mr. Merkel had engaged.
+
+"But they're slowly dying off," Slim reported. "And I don't believe
+Square M ranch will ever be safe to use again."
+
+"Why not?" asked Bud.
+
+"Because there must be some infection in the grass there to have made
+so many of the cattle sicken and die."
+
+"Maybe it was something else," suggested Nort.
+
+"Well, maybe," assented the foreman. "It's about as mysterious as that
+underground river of yours. Had any more warnings, Bud?"
+
+"No, I guess they're done with. And I believe it's a natural cause,
+and not due to any work of enemies, that accounts for the queer way our
+flume acts."
+
+"Um!" spoke Slim musingly, and that was all he would say.
+
+Borrowing horses from their friends, the boy ranchers next day made the
+trip over Snake Mountain and returned to camp, finding matters there in
+good shape. There was an abundance of water in the reservoir, and the
+pipe was flowing freely.
+
+For more than a week nothing happened. The cattle at Flume Valley,
+including those of the boy ranchers, and the herd transferred from
+Square M to save it from the epidemic, were doing well, abundant grass
+and water being their portions.
+
+There was no lack of hard work for the boys and their cowboy
+assistants, for it was not all easy sailing. Occasionally bunches of
+steers would stray, and have to be driven back by hard riding. There
+were night watches to be carried on, and another bunch of cattle was
+shipped away.
+
+Bud, Dick and Nort hazed them over to the railroad, and on the trip a
+small-sized stampede gave them all they wanted to handle. But they
+were true sons of the west, and did not complain.
+
+"Whew! That was hot, while it lasted!" exclaimed Bud, as he and
+cousins managed to get the stampeding animals quieted, after they had
+tried so hard to run off by themselves, in varying directions.
+
+"Yes, a thing like that gives you an appetite," remarked Dick.
+
+"As if _you_ ever needed any stimulant!" laughed Nort. "I never saw
+the time yet when you had to be offered an inducement to sit up to
+grub!"
+
+"You either!" retorted the stout lad. "But, speaking of grub, when do
+we eat, Bud?"
+
+"Might as well make it right soon," was the answer. "Now that we have
+the steers quieted they'll be glad enough to take it easy. I planned
+to water 'em at the next stopping place, and that will give us a chance
+to see what Buck Tooth put up for us."
+
+"Stay there all night; will we?" asked Nort.
+
+"Might as well," assented his cousin. "No use running all the fat off
+our stock. We want 'em to weigh as heavy as possible."
+
+This was good business tact on the part of the boy ranchers. For
+cattle are generally sold by weight, either "on the hoof," which means
+alive and as they stand in the stock yards, or by weight after being
+slaughtered. In the case of ranchers "on the hoof" is generally
+understood.
+
+And driving a bunch of steers at too great a speed from the ranch to
+the railroad would make them thin, "running off their fat," so to
+speak, thus losing all the advantages of the rich fodder to which they
+had had access. And when it is considered that it is not at all
+difficult to cause a steer to lose from ten to fifteen pounds by means
+of poor driving, and when to this statement is added the fact that this
+loss is multiplied in hundreds of steers, Bud's state of mind can
+easily be imagined.
+
+"Yes, we'll get 'em quieted down, and take it easy ourselves,"
+suggested the Western lad. And, a little later when some of the steers
+broke into a run, Nort exclaimed:
+
+"Are they stampeding again?"
+
+"No. I reckon they just smell water," Bud answered.
+
+This proved to be true, and this contagion spread all through the herd,
+though with no ill effects, for the water hole was not far off and,
+reaching it, the animals stopped to drink.
+
+There was some confusion and excitement because so many thirsty cattle
+all wanted to drink at once, but it did not last long, and Bud, Nort
+and Dick were glad when they could slip from their saddles, tossing the
+reins over their ponies' heads as an intimation to the animals not to
+stray.
+
+"Oh boy! But I'm tired!" exclaimed Nort, sighing.
+
+"Add hungry to that and I'm with you," said his brother. For there had
+been days of long and difficult work in preparing this bunch of cattle
+for shipment.
+
+"Getting tired of the game?" asked Bud, as he rustled up some sticks of
+greasewood to make a fire over which they might boil coffee and fry
+bacon.
+
+"Not on your life!" laughed Nort. "We're in the game to stick!"
+
+"Sure thing!" asserted Dick.
+
+They made a simple but ample meal over the camp fire and then, as
+evening settled down over the vast prairies, and quiet enfolded them
+like some soft mantle, they lay on their blankets and gazed at the
+feeding cattle.
+
+The steers were very quiet now, evidently feeling quite satisfied with
+the manner in which they had been treated, and having, of course, no
+intimation of the fate in store for them. They had food and water and
+that is all they required. Overhead was the cloudless sky, in which
+sparkling stars were beginning to stud themselves.
+
+"I hope the market is well up in price when we get to the yards,"
+observed Bud, idly chewing on a spear of grass.
+
+"Yes, it would be dandy to get a big price for this stock," agreed Nort.
+
+The boy ranchers were rapidly becoming interested in the business end
+of their venture, as they had been, for some time, in the more
+picturesque side. The difference of a fraction of a cent in the price
+of cattle on the hoof meant the difference of several hundred of
+dollars where there were many tons of meat to be considered.
+
+"Well, we'd better ride herd a little while, to make sure they get
+bedded down quietly," suggested Bud, as it began to get darker. "Then
+we'll roll up and snooze ourselves."
+
+This "bedding down" of the cattle, meaning thereby inducing them to get
+quiet enough so they would lie down contentedly chewing their cuds, was
+part of the routine of a cowboy's life.
+
+"Some of 'em have already started in," observed Nort, as he went up to
+his pony, which, with the other two animals, had been contentedly
+grazing. "Looks like they'd lived here all their lives."
+
+He indicated a score or more of the steer's that were stretched out on
+the rich grass which at once formed their food and their bed.
+
+"Yes, I reckon we'll have a quiet night," observed Bud.
+
+The three chums slowly rode around the bunch of cattle, the lads
+occasionally breaking into the chorus of some song.
+
+The cattle seemed to like this singing--not that this is to be
+considered a compliment to the voices of Nort, Dick and Bud, though
+their tones were far from unmusical. But the fact is that animals of
+most sorts are fond of music in any form, and nothing so seems to
+soothe and quiet a bunch of cattle, especially at night, as the singing
+of the herders.
+
+Perhaps it is due to this fact that we have so many cowboy songs with
+an interminable number of verses, in which there is little sense or
+sequence--a mere jumble of words, often repeated. The cattle seem to
+care more for the tune than for the sentiment.
+
+At any rate the bunch from Flume Valley grew more quiet as the night
+became darker, and when the remains of their camp fire gleamed dully in
+the blackness, as they made their way back to it, Bud and his cousins
+considered their work done for the day.
+
+"We won't stand any regular watch," Bud said. "I think they'll be all
+right. But if we should hear a disturbance--I mean any one of us--he
+can awaken the others, and we'll do whatever we have to."
+
+"And if we have any luck we won't have to roll out," observed Nort, as
+he spread out his blankets and tarpaulin, which last was to keep the
+dampness of the ground away.
+
+"Then I'm going to cross my fingers for luck," observed Dick.
+
+Save for the occasional distant howl of a coyote, or the uneasy
+movement of an occasional steer, with, now and then, the clashing of
+the horns of some of the beasts, there was silence in the camp. Bud
+was the first to fall asleep, because he was more accustomed to this
+sort of life than were his cousins. But they were rapidly falling in
+with the ways of the west, which teaches a wayfarer to consider home
+wherever he hangs up his hat, and his bed any place he can throw his
+blanket and saddle.
+
+But finally Nort and Dick dropped off into slumber, which became
+sounder as the hours of night passed. All three of the boy ranchers
+were tired and they were in the most healthful state imaginable,
+brought about by their life in the open.
+
+"What hour it was Dick had no idea, but he was suddenly awakened by
+sensing some movement near him--too near for comfort considering his
+exposed sleeping position. For he felt something cold and clammy at
+the back of his neck, as though a chunk of ice, or a hand dipped in
+cold water, had touched him.
+
+"Hi! Who's doing that?" yelled Dick, for he had a sudden dream that he
+was back at school, and some one was playing a trick on him. "Cut it
+out!"
+
+No sooner had he spoken than he realized that he had awakened Nort and
+Bud, for by the flickering light of the embers of the fire he could see
+them sitting up and staring over at him.
+
+"What's the matter?" demanded Bud.
+
+"Something tickled the back of my neck," declared Dick. "I guess a
+coyote must have been picking up scraps of food, and smelled of me.
+Hope he didn't take me for a dead one!"
+
+"Coyote!" exclaimed Bud. "I don't believe you could get one to come
+near you, not as long as you breathed. It must have been a----"
+
+"Snake!" broke in Nort, without thinking of what the word might mean.
+
+"Wow! Don't say that!" cried Dick, and he leaped up, scattering his
+blanket and tarpaulin each in a different direction.
+
+"Shut up!" commanded Bud, laughing. "Do you want to start the cattle
+off again? If it was a snake it won't hurt you, and it was probably
+more scared than you, Dick."
+
+"Yes--maybe!" said the other. He lighted a stick of greasewood at the
+fire, and looked about his part of the sleeping ground. But he found
+nothing in the animal line.
+
+"Guess you dreamed it!" said Nort.
+
+"I certainly did not!" emphatically declared his brother.
+
+"Well, go to sleep again," advised Bud. "If you feel it a second time
+call me!"
+
+"Huh! I'll do that all right!" declared Dick. He carefully shifted
+his sleeping place, making a searching examination of the ground before
+spreading out his tarpaulin. And he was some little time in dropping
+off to slumber again.
+
+But there was no further disturbance in the night, and in the morning
+Bud looked for marks on the ground, declaring the visitor had been a
+prairie dog, which Dick declared his unbelief in, sticking to the snake
+theory as being more sensational.
+
+After breakfast they started to drive the cattle again, reaching the
+railroad yards and successfully transacting the business of selling
+their stock.
+
+It was the night that Bud and his cousins returned from having driven
+the steers to the railroad yard that something happened which again
+brought to the front all their worries and anxieties.
+
+They were all seated about the camp fire, and Pocut Pete had just
+arisen, remarking that he would get ready for his turn at night-riding,
+when there was a sort of hissing in the air over the heads of those
+gathered about the blaze, and something hit the ground in the midst of
+the circle.
+
+"What's that?" exclaimed Nort
+
+"An arrow!" answered Bud, and so it proved. An Indian arrow--of the
+sort used by the Redmen years ago, and hard to pick up now, even as
+relics--quivered in the ground near the blaze. And by the flickering
+flames it was seen that a paper was rolled about it.
+
+In an instant Bud had leaped to his feet, plucked the arrow from the
+ground, and torn off the paper. By the light of the fire he read it.
+
+"Another warning!" cried Bud.
+
+"What does it say?" demanded Dick.
+
+Bud read:
+
+
+"Two wasn't enough. This is the third and last! Leave Flume Valley!"
+
+
+There was silence for a moment, and then Bud, crushing the scrawled
+warning in his hand, cried:
+
+"I'd like to see 'em drive me out!"
+
+"That's th' way to talk!" shouted Yellin' Kid. "We'll stick!"
+
+They gathered about, discussing the sinister warning that had been sent
+to them in such a sensational manner. There was no clue to tell where
+it had come from, for no one had noticed the direction whence the arrow
+had been shot. The message itself was written, or, rather, printed on
+a piece torn from a paper bag, and the writing was in pencil. The
+paper was common enough in those parts, and the use of printing, in
+place of handwriting, would, it seemed, preclude any tracing.
+
+"We'd better keep a double watch to-night," suggested Bud, when a hasty
+inspection in the vicinity of the camp had revealed no one.
+
+"We shore will!" asserted Old Billee.
+
+The night hours passed, a double guard watching with keen eyes for any
+sign of strangers approaching the reservoir or the cattle. But, in
+spite of all precautions, the half-expected happened.
+
+It was toward morning, when Nort and Dick had turned out of warm beds
+to relieve Pocut Pete and Snake Purdee that a confused noise at the
+extreme end of the valley gave notice that something was wrong.
+
+"What's that?" asked Bud, who had ridden into camp at the conclusion of
+his tour of duty.
+
+As if in answer came distant shots, the howls of coyotes and the
+snorting of cattle, mingled with a rush which told its own story.
+
+"Stampede!" yelled Bud. "They're trying to stampede our herd and drive
+'em off! Come on, fellows!"
+
+And all within the sound of his voice rallied to repel the night
+attack, for such it proved to be.
+
+Leaping into their saddles, Nort and Dick followed Bud toward the scene
+of the disturbance. They saw the cattle running to and fro, and in the
+slivers of light that leaped from the muzzles of guns which were shot
+off at intervals, they descried figures swiftly riding backward and
+forward, evidently trying to cut out bunches of cattle.
+
+Action had followed rapidly on the heels of the sinister arrow warning.
+
+
+
+
+CHAPTER XV
+
+THE BRANDING IRON
+
+"Come on, boys! Come on!" shouted Bud, as he spurred off in the
+darkness, followed by Nort and Dick. "They're trying to drive 'em off
+through the lower end of the valley! We've got to stop 'em!"
+
+"You said it!" shouted Dick.
+
+"Who are they?" yelled Nort
+
+Bud had no time to answer. What was needed, then, was quick action to
+prevent his own and his cousins', as well as his father's stock from
+the Square M ranch, being driven off by unscrupulous rustlers.
+
+For that this night attack was made by these marauders of the plains
+was not to be doubted.
+
+"Ride hard, boys! Ride hard!" shouted Old Billee as he galloped up
+beside the boy ranchers.
+
+And they were riding hard--all of them, including the cow punchers who
+had come in from their night's duties, expecting to be relieved. It
+was at this favorable--for them--moment that the rascals had made their
+attack.
+
+It was so dark that only, indistinctly, could the forms of raiders be
+made out. But there were several of them, leaning low over the necks
+of their galloping steeds, and endeavoring to create a panic among the
+cattle so that a stampede would result. Once this started it would be
+a comparatively easy matter for them to "cut out" as many choice
+specimens as possible, driving them to some secret place. There the
+brands could be "blurred," or changed, and Diamond X Second would be
+out several thousands of dollars.
+
+"There they are!" yelled Bud, as, riding between Nort and Dick, he saw
+a group of men swinging their big hats and heard them shouting to
+frighten the already thoroughly roused cattle.
+
+But though Bud thus indicated the presence of the rustlers it was not a
+very clear sight of them that he or his companions had. Only for the
+fact that those of Flume Valley rode together, and saw the indistinct
+forms ahead of them, could it be made certain that the unknown ones
+were the enemy.
+
+"Crack!"
+
+Bud's gun shot out a menacing warning, for he had fired high in the
+air, above the heads of the rustlers. He had borne in mind his
+father's injunction never to shoot at a human being unless vital
+necessity required it.
+
+"And I'd rather lose all my cattle than kill anyone," Bud said
+afterward. "Unless I had to do it to save my life."
+
+It was for this reason that he had fired high, and his example was
+followed by his cousins.
+
+But that this consideration on the part of our friends was not
+appreciated, was made plain, a moment later, when Old Billee exclaimed:
+
+"That was a close one!"
+
+His words followed the whining song of a bullet as it zipped through
+the air, too close to the heads of himself and the boy ranchers to be
+comfortable.
+
+"I'm goin' t' give 'em some of th' same medicine!" shouted Yellin' Kid,
+and his gun spat fire, but straight out, and not at a high angle.
+
+Following it, almost instantly, was a yell of pain from one of the
+rustlers--which one could not be told because of the mix-up and the
+darkness, but it was a yell nevertheless.
+
+"You winged one!" cried Snake Purdee.
+
+"I meant to!" was the Kid's grim answer.
+
+"Fire high, boys!" cried Bud. "If we can scare 'em off, so much the
+better!"
+
+"Don't reckon they're th' kind that scares easy," objected Old Billee.
+"But we've got 'em on the run!" he exclaimed, a moment or two later,
+when Bud and his party had ridden around some intervening bunches of
+cattle, and were headed straight for the night attackers.
+
+This seemed to describe the situation. So promptly had the boys of
+Flume Valley ridden out to repell the raid that the rustlers had no
+time to stampede the cattle, and cut out some to drive away. Now it
+seemed there must be a clash--a coming together of the two forces.
+
+But the rustlers, unscrupulous as they were, evidently knew when
+discretion was the better part of valor. They fired several more
+shots, one of which scratched Old Billee while another gave an ugly
+wound to Snake Purdee.
+
+Then, with yells of defiance, and before our boys could come close
+enough to recognize any of the raiders, the rustlers galloped off, not
+having succeeded in driving away any cattle.
+
+But their attack had not been without damage to Flume Valley stock.
+For two valuable steers had been shot, and so wounded that they had to
+be killed, while several calves were trampled on and crushed into
+shapeless masses.
+
+This, together with two wounded men, Old Billee and Snake, made up the
+sum total of the casualties on the part of the Diamond X Second outfit.
+
+"But they're marked!" shouted Yellin' Kid as he and the others rode
+back to camp. "I got one, I'm sure!"
+
+"I fired low, after I saw they were doing the same, and I saw one
+nearly slump out of his saddle," declared old Billee.
+
+"I'd like to know if they were any of the Hank Fisher or Del Pinzo
+gang," said Bud.
+
+"I wouldn't put it past them," asserted Snake. "We'll ride over t'
+Hank's place, casual like, t'-day, an' see if any of his men are hurt."
+
+Snake spoke rightly of "to-day," for it was getting sunrise-light when
+the battle was over, and the party returned to the tents near the flume
+reservoir.
+
+The night of excitement, following the mysterious warning sent by the
+Indian arrow, had ended, and everyone welcomed the hot, fragrant coffee
+made by Buck Tooth.
+
+When Snake's wound and Billee's scratch had been bandaged, the dead
+calves buried and the best part of the killed steers cut off for fresh
+beef, Bud and his friends took what might be termed an accounting.
+
+The boy ranchers, with Old Billee, rode back over the ground covered in
+the attack of the night. The veteran cow puncher pointed out where the
+rustlers had ridden into the valley, over a pass that crossed a low
+mountain range, which connected, in a fashion, Buffalo Ridge and Snake
+Mountain. This ridge formed the lower boundary of Bud's range, and
+once the cattle had been driven over this they could easily have been
+hazed to Hank Fisher's Double Z ranch.
+
+"Well, there's nothing to make sure it was any of Del Pinzo's gang,
+except general suspicion," remarked Bud, as they were about to ride
+back to camp. "What's the matter?" he asked, for, with an exclamation,
+Nort had leaped from his saddle. The eastern lad was picking up
+something from the ground that had been so lately trampled by steers
+and horses.
+
+"Look!" exclaimed Nort, and he held up a branding iron.
+
+"One of ours?" asked Bud, in rather a commonplace voice.
+
+"Not exactly," Nort answered. "It's marked with a double Z!"
+
+
+
+
+CHAPTER XVI
+
+QUEER ACTIONS
+
+What effect this announcement had on Dick and Bud can easily be
+imagined. Both leaped from their saddles, as Nort had done, and
+gathered close to him as he held the branding iron in his hand.
+
+It was of the usual type, an iron plate, which had been cast in a
+mould, so that the device--two Z letters--formed a depression in the
+smooth surface of the iron plate. On the outer edge was a circle, so
+that when the brand was heated, and pressed on the hide of a steer,
+calf or maverick it would burn the impression of a double Z inside a
+ring--the mark of Hank Fisher's cattle.
+
+"Whew!" exclaimed Dick. "This makes it look bad for them, Bud!"
+
+"Oh, not necessarily, though I'm glad we found it," spoke the western
+lad.
+
+"Why isn't it suspicious?" asked Nort, whose high hopes had been rather
+dashed by Bud's somewhat cool reception of Dick's statement.
+
+"Oh, it's _suspicious_ all right!" Bud hastened to say, "and don't
+imagine I'm making light of you finding this, Nort! I'm mighty glad
+you did! Only we can't make it look bad for Hank Fisher, or the Double
+Z crowd unless we can fasten this on them."
+
+"You mean we can't prove they dropped it here during the raid last
+night?" asked Nort, as he vaulted into the saddle.
+
+"That's it," spoke Bud. "It does look suspicious, I'll admit. But you
+see while this is our range, we couldn't make a fuss just because some
+cowboy from Double Z rode over it. That wouldn't be right. And what's
+to hinder this having been dropped by some cowboy who was merely riding
+over our range?"
+
+"That's possible," admitted Dick.
+
+"But I don't believe it," asserted Nort.
+
+"Nor I," chimed in Bud. "But you got to go slow in making accusations
+out west, unless you're ready to back your opinion up with a gun; and
+we don't want to do that."
+
+"No," Nort admitted. "But Old Billee and Snake said they were going to
+ride over to Double Z to-day, to sort of size up the situation. So
+what's to prevent 'em taking this branding iron along and asking,
+casual like, if they don't want it back?"
+
+"Nothing to stop that," said Bud with a grin. "In fact that's just
+what we'll do. Come on, we'll hit the trail for the camp and make a
+sort of raid on Double Z--only we'll make it to-morrow instead of
+to-day, as it's too late for a long ride."
+
+There were murmurs of surprise and excitement at the camp, when the
+boys rode in with the Double Z branding iron that Nort had picked up at
+the scene of the raid.
+
+"They dropped that last night, sure as horned toads!" cried Snake
+Purdee, whose wound was excuse enough for not being out on duty.
+
+"I reckon," agreed Pocut Pete, who likewise was off duty. "Let's see
+that," and he reached for the iron which had a wooden handle to enable
+a cowboy to manipulate the marker when the branding end was hot.
+
+Bud, so Nort and Dick thought, looked rather curiously at Pocut Pete
+while the latter was examining the iron. And when the strange
+cowboy--strange in the sense that he had not been long in Mr. Merkel's
+service--took out his knife and began whittling away at the wooden
+handle, Bud uttered a sharp cry of:
+
+"Stop!"
+
+"What's the matter?" asked Pocut Pete, with an assumption of innocence,
+which was so plainly an assumption that Nort and Dick exchanged rapid
+glances.
+
+"Don't cut off those initials!" went on Bud. "Maybe by them we can
+tell who owns the iron."
+
+"Initials!" exclaimed Pocut Pete. "I don't see any initials!"
+
+"There they are," and Bud pointed to some, rather faintly cut, on a
+flat place in the handle. "E. C. are the letters, though I don't know
+anybody with them at Double Z."
+
+"I don't, either," said Pocut Pete. "In fact, I didn't see them
+letters, Bud. I was just whittling the handle to see what kind of wood
+it was. Thought maybe I could tell by that."
+
+"All right," spoke Bud, as he again assumed charge of the branding
+iron. And Pocut Pete, with a sharp look at the young rancher, went out
+to the corral where the spare ponies were kept.
+
+"Was he really trying to cut out those initials?" asked Nort, as the
+three boy ranchers passed on to the grub tent, for it was the joyful
+time to eat--one of the three joyful times that came each day.
+
+"I wouldn't say he was doing it _deliberately_," spoke Bud, "but he
+certainly _was_ whittling near those letters. And if he had cut them
+off the owner of the branding iron could easily claim it wasn't his."
+
+"That was queer," declared Dick.
+
+"Very," assented Bud. "In fact Pocut Pete has acted queer ever since
+he's been here. I don't like him, and as soon as dad has another
+puncher to spare I'm going to ask for a change."
+
+The remainder of that day and the night passed quietly. There was no
+other alarm, and riding herd was an easy task. Nor was there any
+stoppage of the water, which ran freely out through the pipe from the
+underground tunnel as though there had never been any interruption of
+its very necessary service.
+
+"Well, let's go!" exclaimed Bud next day, as he and his cousins saddled
+their ponies, and Old Billee called for Yellin' Kid to help catch a
+rather frisky pinto that the old cowboy was going to ride.
+
+"Over to Double Z?" asked Nort.
+
+"Yes, we'll take a sort of a look around their place, and hand back
+this iron," went on Bud, as he slung the implement to his saddle by a
+loop of his lariat.
+
+The ride to Double Z was pleasant enough, for soon the boys and Old
+Billee struck the hill trail, where it was cooler than down in the
+valley.
+
+But if they hoped to discover any incriminating evidence at Hank
+Fisher's place they were disappointed.
+
+There was no sign of Del Pinzo--in fact that wily Mexican half-breed
+was seldom at the ranch proper. Nor was Hank at home. But his foreman
+met the boys and Old Billee.
+
+"Hear about the racket over at our place?" asked Bud, easily enough,
+but with a beating heart. He and his cousins looked around for any
+signs of wounded men, but saw none.
+
+"What racket?" asked Ike Johnson, the foreman.
+
+"Rustlers," put in Old Billee. "They scratched me, shot up Snake
+Purdee and dropped this--or at least we found this after the mix-up
+when we'd druv 'em off!" and he took the branding iron from Bud's
+saddle loop.
+
+"You don't mean to say----" began Ike, with an ugly tone to his voice.
+
+"Don't mean t' say nawthin'!" drawled Old Billee. "That's one of your
+irons, I take it."
+
+"Yes, it is," growled the foreman slowly. "But that don't mean----"
+
+"Course it don't!" pleasantly interrupted the old cowboy, giving the
+young ranchers a slight signal to let him do the talking. "One of your
+boys dropped it, likely, ridin' short-cut across our place, Ike."
+
+"Yes, I remember now, Ed Carr said he lost his. This is it," and the
+foreman of Double Z pointed to the initials.
+
+"Well, tell Ed--is he here now?" asked Billee, interrupting himself.
+
+For an instant--and for an instant only--Ike Johnson hesitated. Then
+he answered:
+
+"No, Ed's ridin' line. I'll give him this when he comes in."
+
+"All right," spoke Billee, with a smile. "We was just passin' and
+stopped with it. How's things, Ike?" he asked with an effort to be
+friendly.
+
+"Oh, so-so! Might be wuss, an' might be a hull lot better."
+
+"I reckon it's that way all over," Billee made answer. "Well, boys,"
+he resumed, "might as well ride back. You gittin' all the water you
+can use from Pocut River, ain't you, Ike?" he asked, turning in his
+saddle.
+
+"Better ask th' boss about that," was the sullen retort. "I reckon
+he'll have suthin' t' say, soon, that you Diamond X folks won't like!"
+
+"Is that a threat?" asked Bud quickly.
+
+"Easy, son, easy!" cautioned Old Billee.
+
+"You can make anythin' yo' like of it!" sneered the Double Z foreman.
+
+And then the boy ranchers and Old Billee rode off.
+
+"Well, we didn't find out much," said Nort, when they were on the
+homeward trail.
+
+"No, but we let 'em know we found that branding iron, and that we knew
+where it belonged," spoke Bud. "That's something!"
+
+They were rather late getting back to camp, for Dick's pony went lame,
+and the others accommodated their pace to his. It was dusk when the
+little party hit the borders of Diamond X Second, and saw the grazing
+cattle.
+
+Bud saw something else, for as he rode ahead he called:
+
+"What's he doing?"
+
+"Who?" asked Nort.
+
+"Pocut Pete," replied Bud. "Looks like he was trying to brand one of
+our cattle with his knife! Look! That's mighty queer!"
+
+
+
+
+CHAPTER XVII
+
+"GERMS!"
+
+Pocut Pete did not become aware of the approach of the boy ranchers and
+Old Billee until they were almost upon him. He was either so intent on
+what he was doing, or else the fact that the ponies were on a grassy
+footing made their advance practically noiseless, that, seemingly, he
+heard nothing.
+
+However it was, the cowboy, about whom Bud entertained suspicious, kept
+on with what he was doing--something strange to one of the
+milder-tempered steers. Something "mighty queer," as Bud had said in a
+whisper to his chums. Which whisper accounted for the fact that Pocut
+Pete had not heard the voice.
+
+So it was not until their shadows, mingling with those of the
+descending night, fell athwart him that the cowboy looked up with a
+start.
+
+"Oh!" exclaimed Pocut Pete, and then Bud and the others saw that he had
+a knife in his hand, and something else. Something that glistened when
+Old Billee struck a match to light his pipe. For the old cowboy had,
+long ago, passed up the inevitable paper cigaret, and used the more
+sedate form of the weed.
+
+"What's the idea?" asked Bud, and his question seemed to give Pocut
+Pete a chance to pull himself together, to answer with more coolness
+than he had exhibited by his first exclamation.
+
+"This steer had some sort of a growth on his shoulder--like a wart,"
+explained the cowboy. "I was just seeing if I could cut it off."
+
+"You'd better be careful!" warned Old Billee.
+
+"Why?" asked Pocut Pete so quickly that the other's remark might have
+well carried a threat, which, in the tone Billee used it, did not.
+
+"You may get horned," went on the veteran cow puncher. For many of the
+cattle on the range of Bud and his cousins "wore their horns long," so
+to speak. Gradually the dehorning system was spreading through the
+west, but such an innovation, found to be most practical from all
+standpoints, took time to grow.
+
+"Oh, this chap isn't dangerous," went on Pocut Pete with a laugh,
+closing his rather large pocket knife with a snap. "All the same, if
+you don't want me to snip off that wart I won't."
+
+"I wouldn't," said Bud. "Not but what I'm glad to have you take an
+interest in the cattle," he went on, "but cutting one with a knife
+might bring on blood poisoning."
+
+"Yes, an' jabbin' a knife into one might set it wild, an' it would rush
+off an' start a stampede," said Billee.
+
+"I realized that," admitted Pocut Pete, "so that's why I didn't do it
+until I got this steer off by himself."
+
+He spoke this truly enough, for the lone animal he had been "operating"
+on was some distance from the main herd.
+
+"I never saw a wart on a steer," spoke Bud, as he urged his pony nearer
+to where the strange cowboy stood on the ground close to the beef
+animal. "It's queer----"
+
+There was a sudden movement. Pocut Pete leaped back and the steer, as
+though taking fright at Bud's advance, lowered its head, and, with a
+loud bellow, sprang away.
+
+"I told you so!" called out Old Billee. "You might 'a' got horned,
+Pete!"
+
+"Oh, I was watching," came the answer. "Yes, warts do, sometimes, come
+on cattle," he went on. "I've cut off lots of 'em. Some beef men
+won't pass 'em if they have any. I thought I was doing you a favor."
+He spoke in an injured tone of voice.
+
+"Well, maybe you were," admitted Bud. "First I thought you were
+someone else."
+
+"One of the Double Z bunch?" asked Pocut Pete with a laugh. "Did you
+find out anything over there?" he inquired as he caught his pony, which
+had been standing near-by, and leaped into the saddle.
+
+"Nary a thing," voiced Old Billee.
+
+And then, as the group, Pocut Pete included, headed back for camp, the
+old cowboy broke into song, roaring out:
+
+ "Send me a letter, kid,
+ Write it yo'self!
+ Put in some news of th' city.
+ For it's lonesome out here,
+ 'Neath th' blue, starry sky,
+ An' cowboys don't get any pity!"
+
+
+"What's struck you?" laughed Bud.
+
+"Oh, I feel sorter so-so," affirmed Old Billee. "We're in for a storm,
+I reckon."
+
+"And that's your weather indication!" chuckled Nort.
+
+"Yeppy," agreed the veteran, and he broke into another verse of the
+interminable song--one of the series that cowboys love to warble.
+
+"What do you think of Pocut Pete?" asked Dick of Bud in the seclusion
+of their own tent that night.
+
+"Oh, I don't know what to think," was the answer. "I did have him down
+for a drinker, or a doper, but he doesn't seem to be either, and he
+does his work well. Only I don't know what to make of his actions
+to-night. Warts! On a steer! That sounded fishy to me!"
+
+"Same here!" agreed Dick.
+
+But as several days passed, and nothing more suspicious occurred, the
+action of Pocut Pete was rather forgotten. Nor was there any further
+trouble with the rustlers, or the lack of water. In spite of the
+warnings and veiled threats that had been received, the black pipe
+still spouted into the reservoir.
+
+And then, like lightning out of a clear sky, came a bolt that gave the
+boy ranchers a shock.
+
+Old Billee riding in from off the distant range one day, called to Bud
+who was opening some of the reservoir gates to let water run to a
+distant trough for the cattle.
+
+"Bad business, Bud!" exclaimed the veteran.
+
+"What's that?" asked the lad, with an instinctive glance at the black
+pipe, whence the water spouted. His first thought was of that.
+
+"There's five of your steers dead, over near the last water trough!"
+was the answer.
+
+"Steers dead!" gasped Bud. "Rustlers?" he asked, quickly.
+
+"Don't 'pear to be," Billee answered. "There isn't a mark on 'em.
+Maybe it's glanders. Better get Doc. Tunison right over."
+
+Which Bud did, by telephone.
+
+The veterinarian, who looked after the health of cattle in that
+vicinity, appeared in due season. Bud, with his cousins and Old Billee
+went out to where the dead cattle lay, now stiff and stark. Some
+buzzards flopped heavily off as the party approached.
+
+"Hum!" mused Dr. Tunison as he began his examination. It did not take
+him long to complete it. "I thought so," he remarked, as he looked at
+Bud.
+
+"What is it?"
+
+"Germs!" was the answer. "The epidemic's struck you, Bud!"
+
+
+
+
+CHAPTER XVIII
+
+ROPED!
+
+Like a blow struck came that announcement to Bud Merkel. And to his
+chums and partners in their first small venture as boy ranchers on
+their own responsibility, the announcement of the veterinarian was
+staggering.
+
+"Germs!" exclaimed Nort.
+
+"Epidemic!" voiced Dick.
+
+"Has it really struck here--the same disease that was among dad's
+cattle?" asked Bud, as though hoping there might be some mistake.
+
+"It's here all right," went on Dr. Tunison, rising from his stooping
+position beside a dead steer. He looked about for a puddle of water in
+which to wash his hands, and, having completed the operation, using a
+disinfectant from a bottle he produced, he added: "Better fence off
+this puddle, Bud. If any of your other cattle happen to drink here
+they'll get the disease, too, and bump off."
+
+That was his way of saying that the steers would die.
+
+"I'll do that!" declared Bud. "We can cut the water off from this part
+of the range. But what causes the epidemic, Doc? Dad was careful not
+to send me any of his infected cattle from Square M, and he said you'd
+examined all that came, and they didn't have any of the trouble."
+
+"They didn't," declared the veterinarian. "I examined them all, and
+nothing was wrong with them. But this epidemic is a germ disease, Bud,
+and we don't exactly know how the germs are carried. It may be
+something the cattle eat; the bunch grass or other fodder, in the
+water; or it may come out of the air. All we know is that certain
+germs, in some, as yet unknown, way, enter into the system of the
+steer. They get into the blood through the mouth or nostril, or
+perhaps from a scratch or cut. And once the germs are there, so rapid
+is the action that the animals die over night--as yours have done, and
+as your father's did."
+
+"Has dad lost any more?" asked Bud.
+
+"Not that I've heard of. In fact I thought by his action, in sending
+the healthy animals of his Square M herd here, and to his other
+ranches, that he'd gotten the best of it. But now the epidemic breaks
+out here. I can't understand it!"
+
+The veterinarian stood looking down at the dead animal, while the
+buzzards patiently waited nearby for the feast they knew belonged to
+them. Evidently they were not fearful of germs.
+
+"What's that funny smell?" suddenly asked Nort.
+
+"That? Oh, it's the smell characteristic of the disease," replied Dr.
+Tunison. "Not very pleasant. I got some of the pus on my
+hands--that's why I washed and disinfected them. Well, Bud, I'm afraid
+you're in for it!"
+
+"You mean the epidemic may run through all my stock?" asked the boy
+rancher, anxiously.
+
+"It may, and that's the reason I'm putting you on your guard. But
+let's hope for the best. We'll act promptly. Fence this place off, or
+don't let any more water here, where other cattle can drink from the
+pool, that must, of necessity, be contaminated, now that I washed my
+hands in it, if for no other reason. Also separate the other cattle
+into as many herds as you can handle. In this way, if the epidemic
+gets among one bunch, you don't stand to lose so many. This is about
+all you can do."
+
+"No preventative measures?" asked Bud.
+
+"No. If the cattle remain healthy they may resist the germs. Nature
+sometimes provides her own remedies. She'll have to, in a case like
+this, where so little is known about this malady that no cure is yet
+available to science."
+
+"That sure is a funny smell--I don't like it!" said Nort again.
+
+"No, it isn't very pleasant," agreed the veterinarian.
+
+And then Bud, who had been in a serious, brown study seemed, for the
+first time, to become aware of the evil odor.
+
+"That smell! That smell!" he cried. "I've smelled it before!"
+
+"Not unless you came in contact with the germs," spoke Dr. Tunison.
+"Where did you smell it, Bud?"
+
+But, as suddenly as he had spoken, Bud Merkel became silent. He seemed
+to be thinking deeply, and as he turned aside he said:
+
+"Oh, maybe it was when Old Billee rode in to tell me he had seen these
+dead steers."
+
+"Possibly," admitted the veterinarian. "The smell is very
+characteristic, as I said. But you'd better arrange to bury these
+animals, Bud."
+
+"There isn't any danger--I mean to humans; is there?" Bud asked. "If
+there is we'll let 'em stay here. The buzzards will make short work of
+'em."
+
+"No, there's no danger to man, even in directly handling the germs.
+That has been proved," said Dr. Tunison. "But if you let the cattle
+lie here, and the buzzards eat 'em, in some manner the disease may be
+carried to your other cattle. Best bury 'em, and fence off this
+water-hole."
+
+Which was done. So the evil-looking buzzards were deprived of a feast,
+and flapped mournfully away.
+
+There were anxious days that followed the appearance of the epidemic
+among the cattle of the boy ranchers. I speak of the cattle as their
+own, and they were, in a sense. For though, of course, Mr. Merkel
+really owned Flume Valley, and put up the cash to start the boys in
+business, he had determined that they should run the place as though it
+was their own. They must stand or fall by what happened. It was the
+only real way to start them in the way of becoming cattlemen, he
+decided.
+
+So, though the boys were young, possibly the youngest ranchers in that
+part of the west, they were in earnest and accepted all the
+responsibilities that went with the venture.
+
+Bud was very thoughtful those anxious days. There was hard work for
+all, since dividing the doubled herds into small units meant that each
+cowboy, including Bud, Nort and Dick, had to look after a certain
+number day and night. But no one shirked, even Buck Tooth working
+unusually hard in addition to doing the cooking. Though Indian braves
+are constitutionally opposed to labor, Buck Tooth made an ideal
+herdsman.
+
+Not as much time was spent in camp as had formerly been the case, as
+the boy ranchers and their older helpers were more often out riding
+herd. But occasionally many of them gathered at the tents to compare
+notes and "feed up," as Snake put it. His wound, received in the fight
+with the rustlers, had healed.
+
+"Some day we'll have regular ranch houses here instead of just a camp,"
+Bud said, as he was riding back one day to look after the herd he had
+assigned to himself.
+
+"Oh, this isn't so bad," spoke Nort.
+
+"Real jolly, I call it!" added Dick.
+
+"If only the water supply keeps up, and no more epidemic comes, we'll
+be all right," Bud announced. "At the same time I can't be sure of
+either."
+
+This was true. Though the water flowed merrily on since the time the
+lads had penetrated the length of the tunnel, there was always an
+uneasy feeling, on the part of the boy ranchers and their friends, that
+it might stop at any time.
+
+"And when it dries up again," Bud declared, "I'm not going to be
+satisfied until I find out what makes it quit flowing!"
+
+"That's the idea!" added Nort. "We'll solve the mystery!"
+
+As the days passed, and no more cattle were found ill or dead from the
+epidemic, the hopes of the boy ranchers began to rise. Had they caught
+the malady in time? Could it be stamped out by the burial of the five
+steers? Time alone--and a longer time than had so far elapsed--could
+tell.
+
+Bud, Nort and Dick each had charge of a herd, the three bunches of
+cattle being pastured on adjoining areas of rich grass.
+
+But the distances separating them were not so great but that Bud and
+his cousins could exchange visits. And it was on one of these
+occasions that there occurred something which cleared up, in part at
+least, the mystery hanging over Flume Valley.
+
+The boy ranchers were about to part for the evening, having spent the
+afternoon together over "grub," cooking at an open fire; and Nort and
+Dick were preparing to ride back to their herds, Bud being on the
+ground, so to speak, where he would "bunk" for the night.
+
+As they rode down into a little swale amid the gathering shadows of the
+night, a bunch of cattle moved uneasily along ahead of them, and as the
+steers parted there was disclosed in their midst the forms of a man and
+a horse.
+
+"Who's that?" suddenly asked Dick.
+
+"It isn't one of our boys," declared Nort.
+
+Bud suddenly sat upright in his saddle. He breathed deeply, and then
+quickly spurred forward. His cousins saw him swinging his lariat
+around his head.
+
+In an instant it went swishing through the air, and, a moment later, as
+the coils settled about the figure of a man who started to leap for his
+pony, Bud let out a yell, shouting:
+
+"Roped! Roped, by Zip Foster!"
+
+
+
+
+CHAPTER XIX
+
+AN EXPEDITION IN THE DARK.
+
+There was a confusion of rope and man. Sock, Bud's pony, braced his
+feet, including the white one that gave him his name, and the lariat
+tightened. There was a scurrying among the cattle, and the lone pony,
+without a rider, galloped off.
+
+Nort and Dick, taken by surprise, had reined their steeds to a stop
+when they saw Bud lassoing the unknown man, but now they spurred up to
+their cousin.
+
+"What is it?" demanded Nort.
+
+"Who is he?" Dick wanted to know.
+
+At that instant a shot cracked, and the fast-gathering darkness was cut
+by a sliver of flame.
+
+"Trying that, are you!" angrily shouted Bud, and he backed his pony
+quickly, pulling the roped man along the ground, until the prostrate
+figure let out a yell.
+
+"My hands are up!" came desperately out of the darkness.
+
+"They'd better be!" retorted Bud. "Can you get off and tie him, Nort?"
+the boy rancher called to his cousin. "Get out your gun, Dick, and
+cover him! He's going to be a bad actor, I'm saying!"
+
+"I'm through!" came the sullen response from the man on the ground.
+"My gun went off by accident."
+
+"Such _accidents_ aren't healthy around here," grimly spoke Bud. "Get
+at him, fellows!"
+
+"Who is he?" asked Nort, as he slipped from his pony, throwing the
+reins forward and on the ground as notice that the animal was to stand.
+
+"And what's that funny smell?" asked Dick. "It's like--like the time
+we found the five dead steers!"
+
+"Yes, and there'll be more dead steers as the result of this!" said
+Bud, and there was a choking in his voice.
+
+A moment later Dick and Nort were standing over the prostrate figure of
+Pocut Pete. His arms were bound firmly to his sides by the tight coil
+of the lariat, held taut by Bud, and the other boys could see that the
+cowboy's gun had slipped from its holster and lay some distance away
+from him. Nort picked up the gun, and then, with quick motions, he and
+Dick bound some coils of Bud's rope around the rascal's feet.
+
+All the fight seemed taken out of him. Without his gun, down on the
+ground and his pony out of reach--he lacked all the prime requisites of
+a cowboy. There was no escape, covered as he was by Bud, who had drawn
+his own .45, and Pocut Pete "jest natcherly caved in," as Old Billee
+described it later.
+
+"Caught you at it, just as I thought I would!" said Bud, when Pete was
+bound and hoisted up on his horse by the boys.
+
+"Go on! Get it over with," was the grim answer. "I know when the game
+is played out, and it was a dirty game from the start. I'd never have
+opened it only I was desperate for money, and he offered me a lot."
+
+"I know who you mean," said Bud. "It sure was a dirty game; and the
+worst of it is that it isn't over yet. That epidemic may spread all
+through our stock!"
+
+Pocut Pete returned no answer as the boys started with him in the
+direction of the camp.
+
+"What was he doing--trying to cut more warts off your cattle?" asked
+Dick.
+
+"Warts!" cried Bud indignantly. "He was infecting them with the germs
+of that disease! Don't you smell the rotten stuff?"
+
+"Oh!" exclaimed Nort. "So _that's_ the game?"
+
+"Yes," spoke Bud bitterly. "I wish I'd acted sooner, when I began to
+suspect him! But I didn't think any one would play a trick like
+this--especially on some one who never had harmed him."
+
+"Has he been infecting your cattle?" asked Nort.
+
+"Sure!" answered Bud. "I've got the goods on him! He had some thin
+glass bottles, with some sort of germ-dope in them. He cut, or
+scratched, the cattle and poured this stuff in the sore. That's how my
+steers got it, and not from being infected by those dad sent over. Oh,
+it sure is a rotten game, just when we were starting, too!"
+
+"He ought to be shot!" indignantly voiced Nort.
+
+"Or strung up!" added Dick.
+
+"I don't care what they do to him!" said Bud. "I'm going to turn him
+over to Old Billee and the boys!"
+
+"Don't do that!" begged the bound figure of Pocut Pete. "They--they
+may lynch me. Take me right to the sheriff!"
+
+"Too far," said Bud shortly. "I don't care what the boys do to you!
+I'm through!"
+
+The prisoner vainly struggled with his bonds, but they held firm.
+
+It need not be written that there was a surprised bunch of cow punchers
+who gathered in the camp of the boy ranchers a little later, when Pocut
+Pete was delivered to them. Indignant voices and looks were noted on
+all sides as his crime was recounted by Bud.
+
+In brief it was this:
+
+From the time of Pocut Pete's arrival Bud had taken a dislike to him,
+and had suspected him, wrongly it appeared now, of being an addict to
+some form of drug, slangily termed "dope." For he had found fragments
+of thin-glass bottles, and had discovered in part of a broken phial,
+the same evil-smelling mixture that, later, was associated with the
+diseased cattle.
+
+Then Bud did not know enough of the danger to act promptly, and even
+when Pocut Pete was discovered, "cutting a wart off a steer," as he
+falsely said, Bud did not know what to make of that. An older person
+might have been suspicious enough to have acted with more promptness,
+but Bud, naturally, had lots to learn.
+
+However, as appeared later, Pocut Pete had secured from some of the
+disease-killed cattle some pus, filled with millions of germs. This
+unpleasant mixture he kept in tiny phials.
+
+How he learned that to inject some of this pus under the hide of a
+steer would infect the animal, not only causing it to die of the
+disease, but to transmit it to others, is not vital to the story.
+Sufficient that Pocut Pete did know this.
+
+And he put his evil knowledge to evil use. He was caught by Bud, Nort
+and Dick in the very act of infecting some of Bud's steers. For when
+search was made in the morning, at the scene of the capture, broken
+bits of phials were discovered, some with that vile, yellow substance
+on them. And an inspection of the cattle showed several with cuts on
+their flanks, into which cuts, it was assumed, the germs had been
+injected, or rubbed.
+
+These animals were at once isolated, to determine what would happen to
+them. The ground near where Pocut Pete had carried on his nefarious
+operations was sprayed with disinfectants, and the cattle that had been
+with those he inoculated were also herded by themselves.
+
+These were all the precautions that could be taken, and then Pocut Pete
+was hurried off to the nearest jail, there to await trial.
+
+"But what set him up to such vile work?" asked Nort, when the prisoner
+had been taken from camp.
+
+"What else but the desire of Hank Fisher to see our stock-raising
+experiment fail?" countered Bud. "This is the doing of those
+scoundrels at Double Z. I only wonder that Del Pinzo wasn't in on the
+game."
+
+"He may be yet," said Dick.
+
+"Well, we'll be on the watch from now on--doubly on the watch,"
+asserted Bud. "They won't put anything like this over on us again!"
+
+"Not if we know it!" joined in his cousins.
+
+It could not be determined, for several days, what the turn would be in
+the case of the cattle into which Pocut Pete had injected germs of the
+disease. Dr. Tunison was sent for, but said he could do nothing more
+than had been done.
+
+"You'll just have to wait and see how many will die," he told Bud.
+"You've done all you could by isolation. And there's one thing in your
+favor. No more of your cattle have been infected by those five that
+first died. We caught that outbreak in time. And if it proves that
+Pocut Pete is the sole source of infection on your ranch, it means that
+only those he managed to cut in his last operation will die."
+
+But it took time to determine this, and while waiting for the outcome
+something else happened which, though it seemed to involve tragedy at
+the time, really resulted in clearing up the mystery and ending the
+water fight at Diamond X.
+
+One morning, about a week after the roping of Pocut Pete, when the boy
+ranchers and their friends were assembled in camp, preparatory to
+starting out on their rounds of riding herd, Buck Tooth, who had gone
+to the reservoir to fish, came running down to the tents much excited.
+
+"He must have caught a big one!" commented Old Billee.
+
+But it was not fish that had aroused the old Indian.
+
+"Water stop! Water him stop all time!" he yelled.
+
+"What's that?" shouted Bud. "Isn't the pipe running?"
+
+"No run!" answered Buck Tooth briefly. "All gone!"
+
+"More trouble!" commented Bud. And then, with a grim tightening of his
+lips, he added: "This time we'll get to the bottom of the mystery!"
+
+There was no doubt about the fact that the water had stopped running.
+As they all raced up the sloping side of the reservoir they saw only a
+few drops trickling from the pipe.
+
+"The third time--I'm going to make it the last if it's possible,"
+declared Bud.
+
+"What yo' aimin' t' do?" asked Old Billee.
+
+"Go through the tunnel from end to end, and both sides, and see where
+the water vanished to," was the answer. "We'll get up a regular
+expedition this time, and maybe take a boat. We'll find out what it
+all means."
+
+"I believe you're right," asserted Snake Purdee. "There's no use
+trying to work Flume Valley if the water supply is goin' to be cut off
+without notice. I'm with you, Bud!"
+
+"So 'm I!" shouted Yellin' Kid. "Whoop-ee! I'm a lone wolf an' this
+is my turn for makin' a noise! Whoopee!"
+
+"Let's find out, first, if the water is coming into the pipe from the
+river," suggested Nort.
+
+"You call up," begged Bud. "I'm going to get ready for this
+expedition. We'll have to start in the dark," he went on, referring to
+the black tunnel that stretched under Snake Mountain. "But we may come
+out into the light. Anyhow, we're going in!"
+
+
+
+
+CHAPTER XX
+
+INTO THE DEPTHS
+
+Preparations for exploring the mysterious tunnel on this occasion were
+much more complete and elaborate than when Bud, Dick and Nort walked
+through it before. And they did not rush off in haste, the moment it
+was discovered that the water no longer came through the reservoir end
+of the pipe line that formed the beginning and end of the old
+underground stream course.
+
+"There's water enough for nearly a week, anyhow," said Bud, in
+discussing their plans. "And if we can't discover the cause of the
+stoppage inside of that time, and get it turned on again, we may as
+well know that and give up Flume Valley as a bad job."
+
+"That's right," chimed in Nort.
+
+"The stoppage is inside the tunnel, that's sure," voiced Dick.
+
+"Yes," answered his cousin. "The water is running in all right from
+the river."
+
+This fact had been ascertained by telephone. The water was running
+freely from Pocut River above the dam, and into the pipe that entered
+the side of the mountain.
+
+Bud's father had been told of the situation, which followed so closely
+on the heels of the discovery of the evil acts of Pocut Pete.
+
+"Doesn't this sort of set you fellows back so you want to give up
+ranching?" Mr. Merkel asked his son and nephews.
+
+"Not a bit!" promptly answered Bud.
+
+"We're going to stick!" added Nort.
+
+"And find out what makes this water stop," contributed Dick. "We'll
+show up Hank Fisher, Del Pinzo and that other bunch of crooks, too!"
+
+"I don't see how Hank could have had anything to do with this water
+stoppage," said Mr. Merkel. "Of course it may develop that he hired
+Pocut Pete to infect our cattle, but even that is doubtful. Those
+fellows are pretty cute. Anyhow, Pocut Pete is where he can't do any
+harm for some time. He won't be tried until fall.
+
+"But it's my idea, boys, that this water stoppage is caused by some
+natural means. We are using an old underground river bed, you realize,
+and there may be what I'd call a 'hole' in it somewhere. The water
+that ought to come to you may drop down that hole."
+
+"But why doesn't it do it all the while?" asked Dick.
+
+"That's one of the mysteries," said his uncle, "one that you'll have to
+solve."
+
+"We went over it all before," spoke Bud, "and we couldn't see even a
+branch passage."
+
+"Well, some of the men are going with you this time," his father said.
+"They're more used to looking for signs than you fellows are, though I
+must say you've done fine, so far!"
+
+As Mr. Merkel had stated, it was decided to send several of the cowboys
+with Bud and his cousins on this expedition into the dark tunnel. Old
+Billee, Yellin' Kid and Snake Purdee would be of the party, which would
+thus consist of six.
+
+In this way, there being safety in numbers, it was hoped that accidents
+might be avoided, or, if they happened, there would be at hand help for
+the unfortunates.
+
+"If we could only take a boat," said Dick, when the preparations were
+almost completed, "it would be great!"
+
+"What could we do with a boat in that stream, which is hardly three
+feet wide in places?" asked his brother. A boat had been mentioned in
+the first excitement, however, but the idea was abandoned as
+impracticable.
+
+"Well, if the flood came, as suddenly as it did when we had to take
+refuge on the ledge, we could float out," answered Dick.
+
+"A boat to hold six men would be too big to carry," spoke Bud. "Even a
+folding canvas one wouldn't answer. But I know what we can do."
+
+"What?" asked Nort.
+
+"We can each take an inner automobile tire. Blown up, they are as good
+as life preservers, and with them fastened to us we can float and be
+carried along by the current, if a flood happens again."
+
+It was decided that this was a wise precaution to take, and from
+Diamond X some inner tubes were sent over--old ones that had outlived
+their usefulness on the car, but which still held air, and would, as
+Bud said, make excellent life preservers.
+
+In order to make a thorough examination it was decided to take food and
+water enough to last the expedition at least two days. It was easy to
+traverse the tunnel in one day, as the boys had proved. But Old Billee
+counseled a slower trip.
+
+"I wish I could go with you," said Mr. Merkel to the boys, when the
+time came for the start, "but I have a shipment of steers to get off,
+and I want to keep watch of this epidemic. It begins to look as if we
+had gotten the best of it, but I'm taking no chances."
+
+"Oh, we'll make out all right, Dad," spoke Bud. "Though we would like
+to have you with us. And when we come back we'll either settle, for
+good and all, this fight for water, or we'll abandon Flume Valley!"
+
+"I'd hate to see you give it up," said the ranchman. "It is an ideal
+place to raise cattle, with the water here. But without it, of course,
+there's no use thinking of it. Well, good luck to you," he called, as
+he turned to go back to Diamond X proper.
+
+As he had said, there had been no further outbreak of the epidemic
+among the cattle of the boy ranchers. The steers which Pocut Pete had
+cut, injecting into them the pus and germs, died, however. And there
+were more of these than Bud and his cousins had counted on.
+
+But if they lost no more than this half-score, and could get the water
+back, all might yet be well.
+
+The water in the reservoir had gone down several feet when the
+expedition started into the tunnel. Much of the fluid had to be drawn
+off to water the thirsty cattle, for it was the height of summer now,
+and the heat, in the middle of the day, was terrific.
+
+But there was still enough of the supply to last for several days.
+Then, if Bud and his companions could not discover the secret of the
+stoppage, and get the water to running again. Flume Valley would have
+to be abandoned.
+
+"Well, I can't see that we can do any more," spoke Bud.
+
+"No; you've got things as well fixed as possible," agreed Old Billee.
+
+"Can't tell when you'll see us again," said Dick to the remaining
+cowboys gathered about the reservoir end of the tunnel to see the
+expedition start in.
+
+"Well, good luck, anyhow!" came the answer.
+
+A number of punchers had been sent over to Flume Valley from Diamond X
+and Triangle B to replace Yellin' Kid, Billee and Snake Purdee who were
+to accompany the boy ranchers.
+
+Suddenly Yellin' Kid broke into song:
+
+ "Leave me alone with a rope an' a saddle,
+ Fold my spurs under my haid!
+ Give me a can of them sweet, yaller peaches,
+ 'Cause why? My true-love is daid!"
+
+
+"Oh, give us something cheerful!" laughed Bud, as the cowboy seemed
+about to start on another verse.
+
+"That's cheerful enough for this occasion," retorted Yellin' Kid.
+"Wait 'till you hear me howl in that tunnel."
+
+"Don't!" begged Dick with a laugh. "It echoes so you'll bring the roof
+down!"
+
+There was a hurried inspection of their weapons and supplies, for each
+was equally needed. The inner tubes of several auto tires had been
+provided and tested, and there was a small air pump with which to
+inflate them.
+
+"All ready?" asked Bud, at length.
+
+"All ready," answered Old Billee. "But I wish I had a hoss!"
+
+"Couldn't use one," retorted Snake Purdee. "It'll work off some of the
+fat, if you walk."
+
+"Hu! Fat!" snorted Old Billee. "I ain't fat!"
+
+"Forward!" suddenly called Bud.
+
+Then with waves of their hands, and with the calling of many "good-bye"
+farewells, the expedition disappeared into the black depths of the
+tunnel.
+
+What would they find? What would be the outcome? Would they ever
+reappear again?
+
+These were questions which more than one asked himself, but no one
+spoke them aloud.
+
+"Now," remarked Bud, when they were well within the long stretch of
+blackness, and lanterns had been lighted, "we walked, the other time,
+on the left-hand side of the water course. What say we try the right
+one this time?"
+
+"Good enough!" decided Old Billee. "We'll be right for once!" he joked.
+
+"But it really is a good idea," declared Snake Purdee. "There might
+have been something--some hidden passage on the side you didn't travel,
+boys. You could easily have missed it in the darkness."
+
+So this was decided on. As a matter of fact in many places it was
+possible for the party to divide and some walk along either side of the
+old stream bed. But this would not be feasible should the water
+suddenly appear again.
+
+And so the expedition moved slowly along. I say slowly, for that speed
+marked their course. They carried a number of lanterns and these were
+flashed over walls and roof as well as on the bottom, to discover, if
+possible, a branch tunnel, or hole, where the water might travel to,
+and thus be shunted off from the reservoir end. But, for several hours
+nothing occurred, and nothing was discovered. Lunch was eaten in the
+blackness, relieved as it was only by the lanterns, and then the
+expedition started off again.
+
+"Here's the place where we were when the water came spouting before,"
+said Bud, as they came opposite the ledge on which he and his cousins
+had taken refuge. "I think we ought to spend some time here and----"
+
+"Hark," suddenly interrupted Nort. "Hear that noise!"
+
+They all heard it--a rushing, roaring sound, like the blowing of a
+mighty wind.
+
+"The water--the water!" cried Bud. "Look out!"
+
+They could hear the noise more plainly, now, and as Snake and Billee
+raised their lanterns, the glows flashed on a white, frothy mass
+approaching through the blackness of the tunnel.
+
+"It's the same as before!" cried Nort. "Get to the ledge! The ledge!"
+
+He made a leap, running ahead to where he saw a more narrow place that
+would enable him to leap across from the right to the left side of the
+channel.
+
+And then, while the others hung back for a moment, and Nort thus dashed
+ahead alone, his companions saw him quickly disappear. The wall of
+water suddenly rushed forward, but it never came quite to the place
+where the party of five now stood in nameless terror--five, for Nort
+had disappeared into the depths of the stream that had so mysteriously
+appeared again out of the blackness.
+
+From whence it came, and whither it was rushing, not to foam entirely
+over that startled group, none in it could say. But it had engulfed
+Nort--that they had seen.
+
+
+
+
+CHAPTER XXI
+
+THE FIGURE ON THE ROCK
+
+Horror and surprise held the five speechless for a moment. Then, as
+they heard the noise of the rushing water, and saw, by the light of
+their lanterns, that it came almost to them, but suddenly turned to the
+right, they came to their senses.
+
+"Nort! Nort!" yelled Dick, his voice being flung back at him in echoes
+from the rocky, vaulted roof of the tunnel.
+
+"What in th' world happened?" asked Old Billee in trembling accents.
+
+"Nort fell into the stream, and was carried away," answered Bud, his
+voice choking.
+
+"But why doesn't the water reach us?" asked Snake.
+
+"That's what we'll have to find out," asserted Bud, bravely. "Come on!"
+
+"But be careful," cautioned Billee. "Something may happen t' us, an'
+then we can't help Nort! Go easy!"
+
+He spoke only in time, for the next moment, with an exclamation of
+horror, Bud and Dick, who had forged ahead, recoiled back.
+
+"Look out!" shouted Bud, and he made such a lurch backward to recover
+his balance that the lantern was flung from his hand. It dropped, as
+they all could see, into the midst of black, swirling waters, white
+foam-capped on top.
+
+And it was into this stream that Nort had fallen and been carried away,
+and into this stream that Bud and Dick had been nearly precipitated as
+they dashed forward.
+
+Bud's lantern was extinguished with a hiss as the waters penetrated it
+and covered the wick. It sank from sight, but not before it had, in a
+flash, illuminated the surface of the water.
+
+"It's a good thing we took the right-hand side," said Billee, as he and
+the others saw what it was that had caused the water to rush almost to
+their feet and then branch off. "I mean it's a good thing, for it may
+help us to solve the mystery. But as for poor Nort----"
+
+He did not finish, but Dick sent up a despairing cry:
+
+"Nort! Oh, Nort! Where are you?"
+
+And only the vaulty echoes answered.
+
+"What are we going to do?" asked Snake, who seemed unable to suggest
+anything.
+
+"Everybody come here with their lanterns," directed Bud. "And light
+that spare one, Billee."
+
+Thus was replaced the one he had dropped in the effort to save himself
+from falling into the same torrent that had engulfed his cousin.
+
+And in the light of the lanterns, the one Nort had carried being
+forever lost, it seemed they all could see the explanation for the
+apparently mysterious action of the underground stream; or, rather, it
+was an explanation of part of the mystery; for this was only the
+beginning.
+
+Beyond where they stood, in the direction of Pocut River, there flowed
+through the ancient channel a body of water larger than that which
+usually filled the underground course. This was accounted for, likely,
+by the fact that it had been stopped, or dammed, by some natural or
+artificial means, and had suddenly been released. Thus the channel was
+more fully filled than usual.
+
+But, as I have said, the water came up to the point where the members
+of the expedition then stood. From there it made a sudden turn to
+their right, as they stood facing the river end of the tunnel. And it
+was this sudden turn--this shift in the course of the underground
+stream--which prevented it from engulfing our friends.
+
+But it had engulfed Nort.
+
+"I see what happened--or, at least, part of it," spoke Bud while the
+others listened. "The waters were suddenly turned on again, or turned
+themselves on, and shot this way. Nort heard them and ran down here to
+jump across the stream-bed, which was then dry. But he must have
+fallen over the edge of this traverse ledge, or channel, as I nearly
+did, and down he went!"
+
+They looked, and agreed that this was very likely how it had taken
+place.
+
+"But can't we save him?" pleaded Dick. "I'm a good swimmer. Let me
+try to get him! Maybe he's lying down there--on the bottom!"
+
+He made as if to take off his coat, but Old Billee grabbed him by the
+arm.
+
+"You'd only go t' your death, boy!" said the old ranchman hoarsely.
+"It's bad enough--as it is!"
+
+"But what happened to Nort?" asked Dick, and there was a sob in his
+voice.
+
+"He must have been carried away--down that stream--wherever it goes,"
+asserted Snake Purdee.
+
+"That's just the point, where does it go?" Dick asked.
+
+"Wait a minute," counseled Bud. "Let's see if we can reason this out."
+He paused to give it thought. "The way this stream is running now," he
+resumed, "wouldn't put any water into our reservoir, would it?"
+
+"No," answered Yellin' Kid, and for once his voice was softened. "Th'
+water is all being shunted down this passage--where Nort fell."
+
+"But," resumed Bud, "this passage has always been here. We didn't see
+it before, as we walked on the other side of the main channel. Then if
+this side channel has always been here, and we managed to get water
+through our pipe when it was here, it stands to reason that it must
+fill in time, enabling the water to run along here," and he indicated
+the regular channel that extended back of them out toward Flume Valley.
+
+"That's so!" cried Old Billee. "There's an end, or a bottom, t' this
+channel somewhere, and poor Nort can't be carried all the way through
+th' earth."
+
+"But--but," faltered Dick. "It may be too late to save him when this
+side passage fills up."
+
+"What I was going to propose," went on Bud, "is that we see if we can't
+follow along this newly-discovered side passage, as we have been
+following the main bed of the underground river."
+
+He paused to let his companions visualize this suggestion.
+
+"Do you think that would be safe?" asked Old Billee. "I mean," he
+added quickly, "will that be th' safest way t' try an' save Nort? I
+won't back down on anything--I guess you know that--but I was just
+wondering if there was some other way."
+
+"There might be," said Bud. "We could go along on the left side of the
+stream, and see if there is a crossing place farther on. We saw some
+narrow places when we were here before, but it's a question how much
+water they'd have in them now."
+
+"Oh, but can't we do something?" cried Dick, now almost sobbing, though
+he was making a brave effort to conquer himself. "Oh, Nort! Nort!
+Where are you?" he cried frenziedly.
+
+But again only the echoes answered.
+
+"Come on!" cried Old Billee suddenly. "We'll try this way. We've got
+t' do something!"
+
+"Leave our packs here," suggested Yellin' Kid, and again his voice was
+low, as if in deference to Dick's feelings. "We can put 'em up on that
+ledge," he added, indicating a small one on their side of the
+underground stream. "The water doesn't appear to have been up there in
+years. If we leave our things here we'll be better able to help
+Nort--if we find him," he added in a voice so low that only Old Billee
+heard.
+
+"Take our lanterns," suggested Snake Purdee.
+
+"And ropes," went on Bud. "We may need 'em!"
+
+Accordingly the food and other supplies, which the searchers after the
+secret of the underground water course had brought with them, were put
+up on the ledge, and then they started down the black passage through
+which the stream appeared to have branched, carrying Nort with it.
+There was room but for one to walk at a time on this "bank," as it
+might be called, of the hidden stream, and they had to proceed in
+single file.
+
+"I'd like to see a map of this place, so we'd know where we were
+going," spoke Old Billee, as he swung his lantern from side to side in
+an endeavor to disclose the hidden secrets of the place.
+
+"I have an idea that the underground stream is shaped like the letter
+T," spoke Bud. "The top, or cross stem, is the part that extends from
+the river to our reservoir. We are now walking along the upright
+piece."
+
+"But if the main part of the T is also a stream, and the water is
+running down that, as it is, instead of along the main stem, it becomes
+for the time being a letter L, doesn't it?" asked Snake.
+
+"Yes," assented Bud. "And as long as the water turns at right angles,
+as it does at the place where Nort fell in, and as long as the water
+runs along this same side passage, we don't get any at Flume Valley.
+The letter T is in our favor, and L is against us."
+
+"But we didn't see anything like this when we were here before,"
+remarked Dick.
+
+"Because we weren't on this side," Bud answered. "And I have an idea
+that, in time, this second passage finally fills with water completely,
+and when it does the stream again flows along the cross stem of the T
+and we get it."
+
+"Mebby you're right," Old Billee agreed. "But this isn't finding Nort."
+
+"Will we--will we ever find him?" faltered Dick.
+
+"Sure!" declared Bud, as heartily as he could.
+
+But as they progressed in the darkness, stopping now and then to look
+about by means of the light, calling again and again, and as no reply
+came, even the heart of the stoutest of them sank in despair.
+
+All they could see was black, rushing water, flowing in a channel it
+appeared to have cut, after countless years, in the solid rock. There
+was a narrow footpath, so to speak, on either side of this stream, and
+it was along this the searchers were walking.
+
+Suddenly Bud, who was in the lead, uttered a strange cry.
+
+"What's the matter?" exclaimed Dick. "Do you see him?"
+
+"No! But look!" went on Bud. "We have come out into a regular
+underground cave! It's as big as a house!"
+
+He flashed his lantern around in a circle, and as the others came up
+and stood beside him, at a spot where the passageway beside the stream
+widened, they saw that they had emerged into a great vault.
+
+And as they stood there, awed and marveling, there came to them, above
+the rustle and whispering of the rushing waters, the sound of a human
+voice--it was as though someone, sorely hurt, had moaned.
+
+"Listen!" cried Dick.
+
+"Hold up your lanterns!" commanded Bud sharply.
+
+As they raised them, throwing the combined light farther out across the
+stream that had widened into a pool in the vault, Dick uttered a cry.
+
+"I see him! I see Nort!" yelled Dick. "There, on the rock!"
+
+And he pointed to the huddled figure of some one on a great rock in the
+middle of the pool of black water, which seemed, a short distance from
+the inflowing stream, to be as quiet as a lake. And, as they watched
+in the gleam of the lights, the figure on the rock moved slightly.
+
+"Nort! Nort!" cried Dick, and his voice was flung back in deafening
+echoes from the vaulted roof.
+
+
+
+
+CHAPTER XXII
+
+THE WATER GATE
+
+While they eagerly watched, the solitary figure on the big rock in the
+midst of that sinister pool again moved slightly, and as it became
+partly erect it was seen to be Nort Shannon.
+
+"We've found him! We've found him!" joyfully cried Dick.
+
+"An' alive, too, if I'm any judge," added Billee.
+
+Dick was stripping off his coat, when Bud placed a hand on his shoulder.
+
+"Wait a minute," advised the western lad.
+
+"But I'm going to get him!" objected the brother. "I'm going to save
+Nort!"
+
+"Maybe it isn't safe, and we may be able to save him in another way,"
+suggested Bud. "I say, Nort," he called. "Are you hurt?"
+
+How eagerly they all waited for the answer, after the echo of Bud's
+voice had ceased reverberating in the big cave!
+
+"Yes--I--I'm all right," came the faint answer across the silent pool.
+"I don't know exactly how I got here. Something hit me on the
+head--after I fell--fell in. I reckon I must have floated near this
+rock and--and just naturally grabbed hold and--pulled myself--up!"
+
+"That's enough! Take it easy now!" called Bud. "We're coming over to
+get you!"
+
+"Sure you're not hurt?" asked Dick, his voice trembling.
+
+"Nothing more than a bump on the head," answered Nort, his own tones
+stronger now. "Not half as bad as I've gotten at football," and he
+laughed a little--the most joyful sound any of them had heard since the
+sweeping away of the boy rancher.
+
+"Well, now we've found him, the next thing is to get him over here,"
+spoke Bud. "Two of us had better swim out there. This water looks to
+be all right," and he stooped down and tested it with his hand. "As
+warm as the river," he added.
+
+"I'm going to swim out!" declared Dick, and this time, as he began to
+"peel," no one stopped him.
+
+"I'll go with you," said Bud. "We'll tie the ropes around our waists
+and they can hold them here on shore. It will be better than taking a
+risk, using the old tires," he added, "and, while there isn't any
+current in the pool now, no telling what may happen."
+
+"Sure you want the ropes," said Old Billee. "But you'd better take a
+tire for Nort," and they did.
+
+"Hold hard, Nort!" called Dick, as he and Bud took off their clothes in
+preparation for the swim. "We're coming!"
+
+"I'll hold hard all right," came the answer back across the pool. "And
+there's something hard here to hold on to, all right."
+
+They did not then realize his meaning, but they understood, later, when
+they made a most amazing discovery.
+
+In a few minutes Dick and Bud were in the water, lariats held by those
+on "shore" tied around their waists; and the two boy ranchers were
+swimming toward the big rock in the middle of the pool. Lanterns at
+the edge of this strange underground body of water gave sufficient
+light to enable the swimmers, and the others, to see Nort now standing
+on the great boulder which emerged from the midst of the black water.
+
+It was the plan of Bud and Dick to help Nort to swim back to where the
+others stood, they supporting him on either side. For though Nort was
+a better swimmer than his brother, in his weakened condition, hit on
+the head as he had said, he might suddenly collapse.
+
+So also might Bud and Dick, or there might suddenly appear a swift
+current in the now quiet pool--that is, quiet beyond where the stream
+flowed in--and in that latter event the lariats would serve to pull
+them all to safety.
+
+"Gee! I thought you were a goner!" gasped Dick, as he climbed out and
+clasped his brother by the hand.
+
+"I would have been, only that I floated near this rock, and managed,
+half unconscious as I was, to grab hold of a projection and pull myself
+up," Nort answered. "That water came up so fast it scared me, and I
+slipped right into it."
+
+"We saw you," said Bud, sitting down on the rock to get his wind, so he
+might be at his best in helping Nort on the return journey.
+
+"It was--awful!" spoke Dick simply, and then he made no further
+reference to his mental agony.
+
+"Well, are you ready to go back?" asked Bud, after a pause, in which
+interim they had called to those across the pool that the lost lad was
+all right.
+
+"I'm ready, yes," was Nort's answer. "But I'd sort of like to see what
+this hard lever-like object is."
+
+"Oh, yes," spoke Dick. "You said you had something hard to hold to.
+Let's have a look--if we only had a light," he added, for it was quite
+dark on the great rock in the midst of the black pool. The light of
+the lanterns did not brightly penetrate that far.
+
+"I have some matches, in a waterproof case, if I didn't lose it out of
+my pocket," said Nort, feeling in his soaking trousers. "Here they
+are," he went on a moment later. And as his hands were drier than
+those of Bud or Dick, Nort opened the box and managed, after one or two
+failures, to strike a light.
+
+As the little taper flared up the three boys on the rock saw, standing
+upright about in the centre of the large boulder a great handle, or
+lever, of copper. The metal gleamed dully red in the flickering light.
+
+"What is it?" asked Bud, as Nort struck another light.
+
+"I don't know," was the answer from Nort. "I discovered it when I was
+crawling about and feeling around. I thought, if worst came to worst,
+I could hold to this if the waters rose."
+
+"They seem to be as high as they're going to get," said Bud. "But this
+sure is queer! Hold your match closer, Nort."
+
+Another of the tapers was lighted, and across the pool came the voice
+of Snake Purdee, asking what was going on.
+
+"There's some sort of a handle, or lever, here," answered Bud, as he
+examined it more closely. "It moves, too," he added as he laid his
+hands on it and pulled it toward him.
+
+"Look out!" cautioned Dick, but it was too late.
+
+Bud had pulled the copper lever toward him, and, in spite of its size
+and weight, it moved easily in what appeared to be a slot in the rock.
+It clicked slightly, as though connected with hidden mechanism.
+
+Then, with a suddenness that was startling, a low but ever-increasing
+roar seemed to fill the cavern in which was the black pool. The roar
+grew louder and louder, and the very rock beneath their feet seemed to
+tremble.
+
+"What have you done?" gasped Dick.
+
+"Search me!" answered Bud in such queer tones that Nort laughed.
+
+And then a strange thing happened. As Nort struck another match he and
+the boys on the rock could see the water all about them beginning to
+recede. Slowly it flowed at first and then, with a rush, it began
+running out of the place as fast as it had run in.
+
+"What's up over there?" called the voice of Old Billee from "shore," so
+to speak. "What you fellers doin' with th' water?"
+
+"I just pulled that lever," sang out Bud.
+
+"Then you've done the trick!" said the old cowboy. "You must have
+opened some gate, and the water's running away. Better swim over here
+while you have the chance. When the water comes back that rock may be
+covered!"
+
+But another strange part of their mysterious adventures was that they
+did not have to swim back. For the water receded so rapidly that, in a
+little while, it was possible to wade from the rock to the stone edge
+of the pool where the other members of the party stood. And wade back
+to their friends Bud, Dick and Nort did.
+
+"Oh, boy! But we're glad to see you!" cried Old Billee, as he caught
+Nort by the hand.
+
+"You let out a mouthful that time!" declared Yellin' Kid, and his voice
+nearly split their ear drums, so magnified was it by the echoing,
+vaulted roof of the cavern.
+
+"But what all happened?" asked Snake Purdee. "Is there some old
+Mexican grain mill under here that has a water-wheel, sluices and
+gates?"
+
+"I give it up," answered Bud. "All I know is that I pulled that copper
+lever--and it's copper so it won't rust off, I reckon--and the water
+began to rush out as fast as it must have come in here."
+
+"It is mighty queer," agreed Old Billee. "Let's go take a look," and
+he started to walk across the intervening space between shore and the
+great rock--a space in which only a few puddles of water now remained.
+
+"Will it be safe?" asked Bud, who had begun to dress, an example
+followed by Dick.
+
+"Why not?" asked Old Billee. "The water can't rise any higher than it
+was when you fellows were on the rock. An', according to your tell,
+there's room enough for us all t' stand there."
+
+"Yes, it's big enough," agreed Bud. "But suppose we all get there, and
+the water begins to come back?"
+
+"We'll turn it loose again with th' lever," answered the old cow
+puncher. "But I reckon it can't fill up this pool again until that
+lever is shifted hack where it was before you yanked it."
+
+"Maybe not," admitted Bud. "Well, let's take a chance. If worst comes
+to worst we can swim back, and I'd like to solve this mystery. I feel
+that we're getting at it now!"
+
+"That's right," said Nort, who was feeling stronger every moment.
+"When I fell in, and was carried away," he said, "I had a wild notion
+that this might lead to the discovery of something. I managed to keep
+my head out of water as I was swept along, until I got a knock on the
+noodle, and that put me partly to sleep. That may have been a good
+thing, too, for they say a partly unconscious person doesn't breathe
+much, and that's why I didn't swallow any water to speak of.
+
+"I was dazed when I must have been swept, or floated, past that rock
+but I came to in time to save myself. Gosh! but I was glad to hear you
+yell though, Dick!" he said.
+
+"Well, let's get over there an' start pryin' out this secret,"
+suggested Old Billee. "This is gettin' mighty interestin'!"
+
+It seemed reasonable to suppose that the water would rise to no greater
+height than it had when the searchers had discovered Nort on the rock.
+And as this boulder was well out of water, and large enough for them
+all to stand on, they would run no risk, even if the flood should start
+to return when they were in the middle of the pool, which, however, was
+a pool no longer, but merely a wet reservoir, so to speak.
+
+"But I don't believe the water will flow back here until you shift that
+lever again, Bud," declared the old ranchman. "And I'm going to have a
+try at it!"
+
+"Isn't it takin' a chance?" asked Snake.
+
+"You got t' take chances in this world!" declared Old Billee.
+
+"Well, let's go!" suggested Bud.
+
+"I think I'll stay here," spoke Nort. "I don't feel quite up to
+walking over those rocks. And you may need some one on this side who
+can throw a rope," he added, as he looked at the lariats.
+
+"All right," assented Bud. "You stay here, Nort."
+
+They left him on the shore, as I call the rocky edge of the pool, with
+a lantern, and, taking other lanterns with them, the little party set
+out. It took them only about three minutes to walk across to the great
+rock, which stood upright in the middle of the cavern floor.
+
+Rising up in almost the very centre was the heavy, copper lever. By
+the light of the lanterns it was examined, and seen to extend down
+through the rock, whither no one knew.
+
+"It works a water gate all right," declared Old Billee. "Let's pull it
+back to where you found it, Bud, and see what happens."
+
+It was with some feelings of apprehension that the others watched as
+Old Billee reached for the copper lever and pulled it toward him, It
+operated as easily as it had for Bud.
+
+And almost as quickly as had taken place on the other occasion, there
+was that roaring, rumbling sound, a noise as of the blowing of a great
+wind, and then the waters began to rush back into the pool.
+
+"Here they come!" yelled Dick, as he stood beside Bud on the rock.
+
+Truly the waters were returning as the hidden gate was closed when
+Billee pulled the lever.
+
+Would they go down again?
+
+That was what each one asked himself.
+
+
+
+
+CHAPTER XXIII
+
+THE CONSPIRATORS
+
+Rapidly rushing, foaming, bubbling and boiling, the waters rushed into
+the mysterious cavern, until they again filled the pool across which
+Bud and Dick had swam to the rescue of Nort on the rock. Now the
+situation was reversed. It was Nort who was on the mainland, or shore,
+so to speak, and the others who were on the rock.
+
+But it was one of their own choosing, in an endeavor to solve the
+mystery, though as Bud and his companions watched the waters creeping
+higher and higher up the surface of the rock on which they stood, their
+hearts were not altogether easy.
+
+"Suppose it covers the rock?" asked Dick.
+
+"Then we'll have to swim back where Nort is," Bud answered.
+
+"Shucks! You won't have to do nothin' of the sort!" declared Old
+Billee stoutly. "She won't come up any farther than it did before!"
+
+And he was right. When the water around the rock lapped the erosion
+mark, which had been worn in the hard stone by centuries of the flow of
+the fluid, the flood ceased. The roaring, bubbling and seething, like
+that which takes place in a canal lock, came to an end, and the water
+of the pool became quiet.
+
+"There! What'd I tell you?" cried Old Billee. "I closed th' water
+gate, that Bud opened to let th' water out, an' she come back. Now all
+we have t' do, so we can walk back, is t' yank this lever again."
+
+"Does it only work two ways?" asked Yellin' Kid, his voice again
+softened, as the mystery of the place seemed to cast a shadow over him
+and the others.
+
+"Seems to," Bud answered, holding his lantern down close to where the
+copper handle entered the rock.
+
+There appeared to be a slot cut in the hard stone--a slot about three
+inches wide, and a foot long, in which the copper lever could be moved
+backward and forward, but not from side to side.
+
+"Let's try the other way, now," suggested Dick.
+
+Once again Old Billee pulled on the copper shaft, which, as they could
+see by the light of all their lanterns combined, seemed to have been
+rudely hammered out, for it bore the rough marks of a primitive forge.
+
+And no sooner had the lever been pulled to its limit in the slot than
+there sounded again the rushing, roaring tumult of noises, and, after a
+little, the water began receding once more.
+
+"We've discovered the secret!" cried Dick.
+
+"No, only part of it," said Bud. "We've got to find where the water
+goes, and if pulling this lever sends it into our reservoir. That's
+the main thing to discover."
+
+"But we're on the track of part of it," went on Dick. "I wonder who
+built this secret water gate, and the lever that operates it?"
+
+"It may be part of the work of the ancient Mexicans, the old Indians or
+the Aztecs, who inhabited this land ages ago," said Bud. "Copper will
+last almost forever, you know, even in water, as it doesn't rust. And
+you've read how the ancient Aztecs used to build great vaults under the
+mountain, and arrange to flood them to keep their gold away from the
+Spaniards."
+
+"Yes, I've read of that," admitted Dick.
+
+"Say, where can you get a book like that?" demanded Old Billee.
+
+"I've got one at the camp," Bud answered. "I'll let you take it. Of
+course my theory may be all wrong," he went on. "But I begin to
+believe we've stumbled on some ancient Aztec water system."
+
+"You don't mean to say those old Mexicans, for that's what the Aztecs
+were, are still hanging around in this cave, turning your water on and
+off, do you?" demanded Dick.
+
+"No, it's some one more modern who's making trouble for us," Bud
+declared. "But we're on the track of a big discovery, I believe.
+Look, the water is almost gone!"
+
+This was true. The pool was emptying itself as it had done before,
+and, in a short time they could walk back to where Nort awaited them.
+
+"What's the next thing to do?" asked Dick.
+
+"Get back where we left our grub and feed our faces," suggested Snake
+Purdee.
+
+"Yes, I think that will be best," Bud said. "Then we can talk over the
+next move. I begin to feel hungry."
+
+"I hope we won't be disappointed," remarked Yellin' Kid and his vocal
+powers seemed to be on the mend, for he called loudly.
+
+"Disappointed? How?" asked Old Billee.
+
+"I mean I hope we find our grub where we left it," Kid explained.
+
+"Why wouldn't it be there?" Old Billee wanted to know. "Do you think
+them Hatchet-texts have sneaked in and took it?"
+
+"You mean Aztecs?" laughed Yellin' Kid. "No, I wasn't referrin' to
+them. I mean I hope our monkeyin' with that copper handle didn't send
+the flood over the place where we left our things."
+
+"I never thought of that," said Bud. "By Zip Foster! I hope nothing
+like that _has_ happened!"
+
+With anxious hearts they hastened back to the place where Nort had been
+swept away. They had left the strange lever set to drain the pool, and
+what state of affairs they would find on returning to their point of
+digression no one could say.
+
+"Maybe we'll find the water running on into Flume Valley," suggested
+Nort, who seemed to be almost himself again, except for a feeling of
+weakness.
+
+"I hope so," spoke Bud.
+
+But this was not the case. On reaching the place where the tunnel
+branched, they found no water there at all. None was running in the
+main channel, and none was turning off down the "stem of the T," to use
+the illustration I first employed.
+
+"Keeps on being strange, doesn't it!" said Bud.
+
+They all agreed with him.
+
+"What's the next move?" asked Dick, as they gazed about, finding their
+food and supplies safe, and no water, to mention, anywhere about.
+
+"Let's grub!" suggested Snake.
+
+"And make a fire and heat the coffee," urged Bud. "I don't believe the
+smoke will do any harm, and there's plenty of dry driftwood in the
+higher places, and on little ledges."
+
+"Some hot coffee would go down mighty well!" remarked Nort.
+
+"Then you're going to have it!" asserted his cousin. They had brought
+some of the cold beverage along in tin flasks, and these were soon
+heating over a little blaze that was kindled along the bank of the
+underground stream that was again dry.
+
+The food and hot drink put new hearts into all of them, especially
+Nort, and when appetites were appeased they gathered about the
+cheerful, if small, blaze, which gave off scarcely any smoke, and held
+a discussion.
+
+"What I think we had better do," said Bud, "is to travel on until we
+come to the place--if such a place there is--where this stream again
+shunts off to the side. For I'm sure there is such a place if we find
+that the water is running into the tunnel from the river."
+
+"We can't be sure of that, though," Old Billee said.
+
+"No, but we can find out when we get to the other end of the tunnel,"
+declared Bud. "My idea is--though, of course, I might be wrong--that
+there are two side passages, so to speak. Sometimes the water branches
+off the main channel and fills the pool where we found Nort on the
+rock. Then it may flow down another channel, farther on, but nearer to
+the river end of the tunnel."
+
+"But if the water came along the main channel, until it got here, and
+then filled the pool to the limit, as was evidently the case,"
+suggested Nort, "why wouldn't the water then back up and go on to our
+reservoir--and it didn't do that."
+
+"There may be some outlet from that pool and cavern where we were,"
+said Bud.
+
+They considered this for a moment, and agreed that he might be right.
+
+"Then what we've got to look for," went on Bud, "is another side
+passage where the water is shunted off, that is, providing it is not
+cut off at the river pipe. And if there is such a passage it must be
+on the right-hand side of the stream, as was the one where Nort fell
+in. For we went all along the left-hand bank the other time, and
+didn't discover anything."
+
+"And suppose we find the second branch stream now--what will we do?"
+asked Snake.
+
+"Two of us will come back and work the lever, while the others stay at
+the second stream to see what happens," was Bud's answer. "Come on;
+let's go!"
+
+They put out the fire, packed their belongings, and, making sure that
+Nort was able to travel, they set out again. Nort's garments were
+soaking wet, or, rather, they had been, but there was a current of warm
+air in the tunnel, and soon he began to dry out, for which he was very
+thankful.
+
+They found the second branching stream sooner than they expected. It
+was less than a quarter of a mile from the first, or the one into which
+Nort had fallen, and it was almost of exactly the same character.
+
+"Look out! Here it is!" cried Bud who saw it first, his lantern
+gleaming on the swiftly-rushing water. "Go easy!"
+
+And "easy" they went, reaching the edge of the ledge below which flowed
+the mysterious, powerful current.
+
+"We can go along here, just as we did before. Here's another branch
+tunnel!" announced Dick, holding up his lantern, and showing a wide,
+high passage, the bottom and middle part of which was occupied by the
+stream.
+
+"I wonder how many of them there are?" remarked Nort as he and the
+others turned into the black opening, which seemed to slope as though
+descending a hill. This gave greater force to this stream of water.
+
+"And I wonder if it also runs into a cavern, with a rock and a copper
+lever in the middle!" voiced Dick.
+
+"Hope we find out soon," spoke Bud. "This is getting more and more
+queer all the while."
+
+They tramped on in the blackness that was relieved only by their
+swaying lanterns. They walked beside the strange, underground stream,
+and they had progressed farther than along the other branching body of
+water when Old Billee, who was ahead just then, suddenly halted and
+uttered a warning.
+
+"Listen!"
+
+"What is it?" asked Yellin' Kid, in his usual tones, but Billee reached
+back and gave him such a dig in the ribs that Kid subsided with a grunt.
+
+"I hear talkin'!" whispered Billee. "Voices! There's some one else in
+this place than us! Listen!"
+
+They stopped and strained their sense of hearing. And then, above the
+slithering murmur of the water, they all distinctly heard a voice say:
+
+"I think we've fixed 'em this time! They won't steal any more water
+from Pocut River!"
+
+The boy ranchers looked at each other.
+
+"Del Pinzo!" whispered Nort.
+
+"As sure as Zip Foster ever ate ham and eggs!" agreed Bud.
+
+"Hush!" begged Old Billee.
+
+And as they became quiet again they heard another voice say:
+
+"I guess it's all up with 'em now. We might as well light out and
+touch off the fuse!"
+
+"Whew!" softly whistled Bud.
+
+Together the party of searchers moved softly forward. Suddenly the
+passage along the bank of the mysterious stream turned sharply, almost
+at a right angle.
+
+And there, in what appeared to be a small cave, excavation or cavern,
+high in the upper wall was disclosed a roughly circular opening, like a
+window or port hole. Through this port hole a light showed, and
+outlined in the light were several rough-appearing men, leaning
+together over what might have been a table.
+
+"Del Pinzo!" murmured Dick.
+
+"Conspirators!" exclaimed Bud. "They're the ones that's been turning
+this water on and off! We're on the track of the mystery now!"
+
+Whether he spoke loudly enough to be heard, or whether some other sound
+made by the searchers alarmed the men in the upper niche, was not
+disclosed just then.
+
+But the light suddenly went out, and confused sounds followed.
+
+And chief among these sounds was the rushing, roaring noise, the
+blowing as of a mighty wind, and the water near the boy ranchers and
+their companions was strangely agitated.
+
+
+
+
+CHAPTER XXIV
+
+A POWERFUL STREAM
+
+"Better look out!" came the high-pitched voice of Yellin' Kid.
+
+"There may be a flood here!" added Old Billee.
+
+"Can't we get those rascals?" cried Snake Purdee. "I'd 'a' had th'
+drop on 'em in another second if they hadn't doused that glim!"
+
+As he spoke they could all hear the rush of iron-nailed shoes when the
+wearers of them scrambled over hard rocks in their effort to escape.
+
+Mingled with that sound was the strange one of rushing water.
+Realizing that danger might come to them more through the agency of the
+strangely-acting underground stream than from the actions of the
+conspirators, Bud and Nort flashed their lanterns on the water-course
+behind them and around the bend which they had turned to behold the
+strange scene.
+
+"It's going down!" cried Bud, for there was no longer any advantage in
+concealment or silence, as long as Del Pinzo and the others had fled.
+"It's receding!"
+
+"Just as the other did!" added Dick. "They must have opened a gate
+here and let the water out!"
+
+"They've done something!" cried Bud, "and we've got to find out what it
+is."
+
+"Did you hear that about a fuse?" demanded Snake. "Maybe they're going
+to blow the place up!"
+
+"If they do, and the tunnel caves in, good-bye to my water!" said Bud.
+
+"Yes, and good-night to _us_!" grimly added Old Billee.
+
+"Come on!" cried Yellin' Kid. "Let's see what's up there in that hole
+in the wall, anyhow!"
+
+"And have your guns ready!" warned Snake Purdee.
+
+However, as it developed, the weapons were not needed. When the boy
+ranchers and their friends managed to scramble up the rocky way, above
+and to the right of the second hidden, branching stream, and found
+themselves in what was virtually a little natural recess hollowed out
+of the rocky wall, they saw that it was deserted.
+
+But there were plain evidences of the fact that the men they had seen
+had fled in a hurry, as, indeed, they had practically witnessed.
+Playing cards, cigarettes, tobacco and bottles were scattered on a rude
+wooden table, and there were several candle-ends stuck in the necks of
+flasks. The smell of the extinguished candles was heavy on the air.
+
+"But where did they go?" asked Bud, when a hasty glance around the
+rocky room disclosed no occupants.
+
+"What's that?" asked Dick, pointing to what seemed to be a hole in the
+floor at one corner.
+
+"It's a passage!" cried Billee, holding his lantern above it. "An' big
+enough, even for me! I'm going down!"
+
+"Will it be safe?" asked Nort. "It may lead into the stream, or to
+where they have planted a mine--they spoke of a fuse----"
+
+"You've got to take chances in times like these!" declared Old Billee.
+"I guess if they went down it will suit us."
+
+"Unless they can close it up, or turn water in," suggested Snake,
+dubiously.
+
+"Git out! I'm going down!" stoutly declared the rather fleshy veteran
+cow puncher, and when he let himself down the hole the others followed.
+
+There was a natural stairway, or what served the same purpose, leading
+down out of the stone room where the conspirators had been evidently
+plotting so far underground. The passage went down, at first, like a
+flight of steep, cellar stairs. Then it straightened out, and, after
+twists and turns, led upward.
+
+"Where are we going?" asked Nort.
+
+"Nobody knows!" grimly answered Bud. "But it's safe so far!"
+
+"And we're right on their trail!" added Snake.
+
+"How do you know?" asked Billee.
+
+For answer Snake paused and pointed to a smouldering cigarette stub on
+the rocky floor of the passage that had led out of the conspirators'
+niche.
+
+"That wasn't dropped many minutes ago," declared the cowboy. "They
+came along here."
+
+This was evident, but it was also evident that Del Pinzo and his
+conspirators were sufficiently in advance to escape. For, with another
+sudden turn, the passage led to another natural, rocky stairway, and
+when this had been mounted the boy ranchers found themselves again in
+the main tunnel.
+
+"What's this?" cried Bud, when it was evident that they had come back
+to the place whence they had started, but farther on, and nearer to the
+river end of the tunnel. "This is a regular maze!"
+
+"But where is Del Pinzo?" asked Dick.
+
+"Out there, I fancy," and Nort pointed to where the main tunnel
+extended under the mountain and beyond, to the dam in Pocut River.
+"They've gotten away!"
+
+"And about time, too!" added Snake, "or they'd be trapped as we may be!"
+
+"Trapped!" cried Old Billee. "What do you mean?"
+
+"I mean there's a mine set here, somewhere! Don't you smell powder
+smoke?"
+
+A sharp, acrid odor, once smelled never forgotten, came to the nostrils
+of all as they stood there in the tunnel, while the stream flowed
+beside them. Whatever the conspirators had done, they had, evidently,
+not shut off all the water.
+
+"There it is!" cried Dick, and he pointed to where, in the light of the
+lanterns, there could be seen, slowly ascending, a thin wisp of smoke.
+
+"Look out!" yelled Old Billee as Dick dashed forward. "It may explode!"
+
+Then, as Dick rushed up with his lantern, they saw trailing over the
+floor of the tunnel, and on the same side of the stream as themselves,
+a thin white fuse, like a sinister snake. It was this burning fuse
+which caused the smoke.
+
+It was the work of but an instant for Dick to step on it, and
+extinguish the smouldering spark, while it yet had some distance to
+travel before the fuse lost itself in a mass of rocks.
+
+"Whew! That was a close call!" exclaimed. Bud, when the fuse was
+entirely out.
+
+"Let's see where it leads to," suggested Snake.
+
+They followed it up, and discovered a hidden mine of explosives, tamped
+down into a hole that had been drilled in the rocky floor. Iron bars,
+hammers and other mining implements showed that the perpetrators of the
+dastardly deed had evidently fled in a hurry.
+
+"They were going to blow up the tunnel!" cried Nort.
+
+"And when that collapsed it would mean the end of Flume Valley," spoke
+Bud soberly.
+
+"We never could have opened the tunnel again, with all these strange,
+branching streams playing around inside."
+
+"But we reached here just in time!" declared Old Billee. "Now let's
+get t' th' bottom of this. We know there's a main stream, an' two
+branching streams. One of th' branching streams is controlled by th'
+water gate with th' copper handle."
+
+"And there must be another gate here, or else Del Pinzo and his crowd
+couldn't have shut off the water as they did before they ran away,"
+went on Bud. "There must be a whole maze of water-courses in this old
+tunnel. Probably the Aztecs dug 'em to save their gold and other
+valuables. But I'd like to know what that roaring is?" and as Bud and
+the others listened they could hear a subdued murmur, a rumbling and
+roaring sound, that seemed to shake the whole tunnel near where they
+stood.
+
+"Maybe this leads to it," suggested Dick, as he walked along and
+suddenly flashed his lantern across another opening--a natural stairway
+leading down into black depths.
+
+"Let's try it," said Bud.
+
+Down it they went, one at a time, carrying their lanterns. And as they
+advanced, descending until they came to a level passage, the murmur and
+roaring became louder.
+
+"Would you look at that!" suddenly cried. Bud, in an awe-stricken
+voice, as he came to a stop and pointed ahead.
+
+And then, as the others gathered about him and looked, they saw a
+wondrous sight.
+
+They had entered a cavern, similar to the one where Nort had been
+found, but not so large. And from the very centre, it appeared, of the
+uneven rocky floor of the cave there spouted out a stream of water
+about three inches in diameter.
+
+Solid white was this stream of water, like a bar of glass, and it shot
+out of a round hole in the floor as a stream comes from the nozzle of a
+fire hose. It was inclined at an angle of about forty-five degrees,
+was this strange stream of water, and whence it came and whither it
+went to the boys and their friends could only guess.
+
+It was this powerful, rushing stream, under immense head and power it
+seemed, that caused the rumbling, roaring sound. It appeared to strike
+against some rocky wall a long distance off, so far that the light of
+the lanterns could not penetrate to it, and the searchers did not feel
+like venturing beyond the point where the terrific stream issued.
+
+That it was of awful power was evidenced a moment later, for Bud, who
+had picked up one of the bars of iron, used by the conspirators to set
+their sinister mine, approached the stream and, raising the bar,
+brought it down with all his force on the white, spurting jet.
+
+On an instant the heavy rod was torn from his grasp, and whirled
+forward into the blackness beyond. There was a ringing, metallic sound
+as it hit some distant rock, and then it came bounding back, sliding
+across the rocky floor to the very feet of the searchers.
+
+"Look at that!" murmured Bud, as he stooped and picked up the bar. It
+was bent and twisted into a sort of combined S and U shape, mute
+evidence of the terrific power of the stream.
+
+"That would bore right through a man!" said Dick.
+
+"Like making a hole in cheese!" added Old Billee. "This is a terrible
+place! Let's get out!"
+
+
+
+
+CHAPTER XXV
+
+HAPPY VALLEY
+
+Leaving behind them the roaring, rumbling jet of white water that came
+from the unknown and went thitherward, the boy ranchers and their
+friends made their way back to the main tunnel.
+
+"Well, there are two things we have to settle," declared Bud, when they
+had sat down on convenient rocks, near the running stream, and began to
+consider matters.
+
+"What are they?" asked "Nort.
+
+"One is, what effect has the turning of that lever we worked on the
+main stream? The other is, where is the lever that Del Pinzo and his
+gang shifted to cause this second branch stream to stop running?"
+
+"And when we find answers to those two questions," said Dick, "I think
+we'll have solved the mystery."
+
+"Right!" cried Bud. "So let's get at them. In the first place some of
+us will go back and shift the lever on the big rock in the first cave,
+while some of us stay here to see what happens."
+
+The party was divided and when watches had been adjusted to mark the
+same time, so it might be known how many minutes elapsed between the
+shifting of the lever and any noticeable effect, Dick, Old Billee and
+Snake went to the first cave--that of the huge boulder.
+
+It did not take long to demonstrate that when the water flowed from the
+main stream into that side branch, the stream nearer the river end of
+the tunnel went dry. But even with that no water passed along the main
+tunnel so that it would flow into the reservoir of Flume Valley.
+
+"The water must flow out of the first big cave by some outlet we know
+nothing about," decided Bud. "Now we'll look for the second water
+gate."
+
+They found the lever that controlled this in a corner of the upper,
+rocky room where Del Pinzo and his conspirators had been plotting when
+discovered. And when this lever was pulled from the position in which
+the seekers found it after the Mexican half-breed fled, the second
+stream (by which I mean the one nearest the river end of the tunnel)
+filled with water. But this did not affect the first.
+
+And not until both levers were set at positions which caused the branch
+streams to empty, did any water fill the end of the tunnel near Bud's
+ranch.
+
+But when this had been done; when the secret of working the levers was
+discovered, and water was once again flowing along the valley end of
+the tunnel, where the stream bed had been dry for two days, then Bud
+cried:
+
+"The fight is over and we've won!"
+
+"I wouldn't say that yet," spoke Old Billee cautiously, "Del Pinzo an'
+Hank Fisher are still around an' above ground. But I guess you've put
+a crimp in 'em, boys!"
+
+"I reckon!" shouted Yellin' Kid. "But are we sure that the water now
+goes to Flume Valley?"
+
+"We'll soon find out," declared Bud. "We're almost out of the tunnel
+now, and we can 'phone back and ask."
+
+And a little later they did emerge from the mysterious underground
+tunnel, with its still stranger water courses. But what was their
+surprise to find that night had fallen--in fact it was not exactly
+night, but nearly morning of the next day.
+
+For a moment coming out into the dark night bewildered them. And then,
+as they stood at the mouth of the mysterious tunnel under the mountain,
+there was a sharp crack.
+
+"Look out!" yelled Bud, as a bullet "zinged" viciously over their heads.
+
+In an instant Old Billee had whipped out his gun and sent a shot toward
+a group of horsemen along the river bank.
+
+"There they are! Del Pinzo and his gang!" yelled Dick, as another
+bullet sang over his head. "Come on! Let's get 'em!"
+
+"No use!" drawled Snake. "They've got hosses--we ain't!"
+
+And a moment later the gang of conspirators, firing another harmless
+shot, swept out of view.
+
+A group of men swarmed from the store and adjacent shacks, roused by
+the early-morning shooting, and with amazement they greeted our friends
+and heard the strange story.
+
+"What day is it?" asked Bud.
+
+"Friday," some one answered.
+
+The mystery-solvers looked at one another in amazement.
+
+They had been in the tunnel nearly forty-eight hours without sleep, nor
+did they feel the need of it, so exciting were the events that
+transpired.
+
+But late, or, rather, early as it was, they managed to get in the store
+to use the telephone. And when the gray dawn was breaking across Pocut
+River, Bud learned, over the wire, from one of his father's cowboys
+left at Flume Valley, that the reservoir was again being filled.
+
+"Hurray! It's all right!" yelled Bud, almost as loudly as the Kid
+would have done. "I guess, from now on, we'll have no trouble. But
+I'm going to see if we can't get Del Pinzo. He and his gang certainly
+tried to blow up the place, and us with it."
+
+"To say nothing of trying, as I believe, to drown, us like rats in
+there, by shutting off and turning on those queer streams," added Nort.
+
+"Do you think they really meant to drown us or blow us up?" asked Dick.
+
+That question was never answered, for Del Pinzo and his more intimate
+associates disappeared after their flight from the tunnel, when they
+fled following the shifting of the lever and the lighting of the fuse.
+
+There was dynamite tamped in among the rocks, and but for the stamping
+out of the fuse the tunnel never would have carried any more water to
+Flume Valley, and those in it might never have come out.
+
+Hank Fisher stoutly denied that Del Pinzo was acting for him either in
+planting the explosives or in shutting off the water from the reservoir
+of the boy ranchers. But everyone had their suspicions.
+
+For that it was Del Pinzo who had sent, or caused to be sent the
+mysterious warnings, no one doubted. Nor did anyone doubt but that the
+vicious Mexican half-breed had played tricks with the water.
+
+For that is what they amounted to--tricks. Who built the
+copper-lever-controlled water gates, putting them in to utilize the
+winding underground streams, no one could tell. It may have been the
+Aztecs. The powerful, slanting stream of water, it was discovered,
+formed the outlet of the shunted-in-river stream when the two side
+channels were opened so that Flume Valley's water supply was cut off.
+
+The water gates and the underground streams formed the chief mystery,
+and these never could be fully explored. It was thought too dangerous.
+How Del Pinzo discovered the workings of the levers, utilizing them to
+try to end the rule of the boy ranchers in Flume Valley, was not
+disclosed for many years.
+
+"You won't have any further trouble, now that the gates are closed and
+the levers taken off," Mr. Merkel said, for that had been done.
+"You'll get all the water you want in Flume Valley."
+
+"Guess I'll call it Happy Valley," said Bud, "for everything is coming
+out right, now."
+
+"In spite of black rabbits!" chuckled Old Billee.
+
+"Yes, even with black jacks!" laughed Bud. "Everything is working
+fine, now."
+
+And so it was. For with the discovery of the secret water gates and
+the disappearance of Del Pinzo, the epidemic died away. Though this,
+of course, was due to the arrest of Pocut Pete.
+
+That scoundrel was found guilty and sentenced to a long term in prison.
+But he kept his counsel, and never actually confessed that it was Hank
+Fisher who set him to this dastardly trick--if, indeed, it was that
+unscrupulous ranchman of Double Z.
+
+That it was rustlers from Double Z who had tried to drive off some of
+the boy ranchers' cattle was not doubted, the finding of the branding
+iron being regarded as telltale evidence. But this was not enough to
+cause any arrests.
+
+"Well, what are we going to do next?" asked Dick, of his brother and
+cousin, when they were fishing in the reservoir one evening, as, with
+the closing of the hidden gates and the uninterrupted flow of the
+water, many more finny prizes could be hooked.
+
+"Get ready for a big shipment of cattle," said Bud. "I never saw any
+finer stock than we have here in Happy Valley. That's our next
+move--reap the benefits of our hard work."
+
+But the lads did more than that. And those of you who wish to follow
+their fortunes further may do go in the next volume of this series,
+which will be called: "The Boy Ranchers on the Trail; or Diamond X
+After Cattle Rustlers."
+
+"Who's that down at camp?" asked Dick, as he pulled up a good-sized
+fish and put it beside him on the grass.
+
+"Looks like Nell and your mother," said Nort to Bud.
+
+"It is!" Bud cried. "They said they'd come over, and Nell promised to
+bring a pie! Come on; we got enough fish!"
+
+And down the reservoir rushed the boy ranchers to greet their visitors.
+
+"Any pie, Nell?" cried Bud.
+
+"Sure," was the answer. "But it's for company--Dick and Nort!"
+
+"Ho! I'd like to see 'em grab it all!" challenged Bud, as he reached
+for the basket his sister held. "By Zip Foster I would!"
+
+"Say, who is Zip Foster anyhow?" demanded Nort.
+
+"Oh, I'll tell you--later!" chuckled Bud, and, as he removed the cover
+of the basket, delighted "Oh!" and "Ah!" exclamations came from him and
+his cousins at the sight within.
+
+Some of the cowboys came riding back to camp from the round-up, Old
+Billee cheerfully chanting:
+
+ "Oh, bury me deep on th' lone prairie!"
+
+
+And with this happy mingling of the joyful and sad we will take leave
+of the boy ranchers for a time.

+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.

+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ https://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
