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
