"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," a.s.sented 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!
"h.e.l.lo! What"s the idea?" asked Nort.
"Did you do it on purpose?" asked d.i.c.k.
"Why, no, of course not!" a.s.serted 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 d.i.c.k.
"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 pa.s.sage 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 d.i.c.k.
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 d.i.c.k 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 d.i.c.k 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!"
