“We will go down the hole and find out what we can,” said Jack. “You get the others and follow us as soon as you are able to. The girls will have told Tooku and Yamen by now, and maybe they will be on the way here with one or two of the servants. I expect Paul’s mother will send for some soldiers, too.”
Beowald did not understand all that Jack said, for the boy did not speak the Baronian language very well as yet. Paul quickly translated for him, and Beowald nodded his head.
“Do not fall into the hands of the robbers,” he said. “Why do you not wait here until I come back?”
“I go to rescue my men,” said Prince Paul haughtily. “Where they go, I follow.”
“You must do as you wish,” said the goatherd. Jack slid down into the hole, and took hold of the rope. He went down and down, whilst Mike shone his torch on to him. Beowald waited patiently, seeing nothing, but knowing by his ears all that was happening.
The hole went down for a long way. Jack swung on the rope, his arms getting tired. Then he found that there were rough ledges here and there on the sides of the hole, on which he could rest his feet now and again, to relieve his arms.
The hole came to an end at last. Jack felt his toes touching ground once more. He let go the rope and felt round with his hands. He could feel nothing. The hole must have come out into some kind of cave. The boy could hear no sound of any sort, and he thought it would be safe to switch on his torch.
He switched it on, and saw that, as he had imagined, he was in a cave, through the roof of which the hole showed, dark and round. “I wonder if this is the robbers’ lair,” thought the boy, flashing the torch around. But there was nothing at all in the rocky cave, whose rugged walls threw back the gleam of the torch.
Mike’s feet appeared at the bottom of the hole and the boy jumped down beside Jack. Then came Paul. They all stood together, examining the cave.
“It doesn’t look as if anyone lives here at all,” said Mike. “There are no beds where you might expect the robbers to sleep, not a sign of any pot or pan. I don’t believe this is their lair.”
“Well, what is it, then?” demanded Jack. “I saw them go down here, didn’t I? Goodness knows how Ranni and Pilescu were taken down, with their hands tied! Where can they be?”
“They’re nowhere here at all,” said Paul, flashing his torch into every corner. “It’s odd. What can have become of them?”
It really was a puzzle. Jack began to go round the little cave, his footsteps echoing in a weird way. He flashed his torch up and down the walls, and suddenly came to a stop.
“Here’s another way out!” he said. “Look! It’s quite plain to see. I’m surprised we didn’t see it before when we shone our torches round.”
The boys looked. They saw that halfway up the opposite wall of the cave was a narrow opening. They jumped on to a ledge and peered through it. It was plain that it led out of the cave, and was a passage through the rock.
“Come on,” said Jack. “This is the way the robbers must have gone. I’ll go first!”
He was soon in the passage that led from the cave. He flashed his torch in front of him. The way was dark and rough, and the passage curved as it went, going downwards all the time. Where in the world did it lead to!
The River in the Mountain
As the boys crept down the rocky passage, they suddenly heard a curious noise in the distance. They stopped.
“What’s that noise?” asked Jack. It was a kind of rumbling, gurgling sound, sometimes loud and sometimes soft. The boys listened.
“I don’t know,” said Mike, at last. “Come on. Maybe we shall find out.”
On they went again, and very soon they discovered what the queer noise was. It was made by water! It was a waterfall in the mountain, a thing the children had not even thought of! They came out into a big cave, and at one end fell a great stream of water. The cave was damp and cold, and the boys shivered.
They went over to the curious waterfall. “I suppose the snow melts on the top of the mountain and the water finds its way down here,” said Jack, thoughtfully. “It must run through a rocky passage, something like the one we have just been in, and then, when the passage ends, the water tumbles down with that rumbling noise. I’m quite wet with the spray!”
The water fell steadily from a hole in the roof of the cave, where, as Jack said, there must be a tunnel or passage down which the water ran before it fell into the cave.
“Where does the water go to, I wonder?” said Mike. “It rushes off into that tunnel, look — and becomes a kind of river going through the mountain. I think it’s weird. I wonder if the robbers live in this cave — but there still seems to be no sign of them or their belongings. After all, if people live somewhere, even in a cave, they scatter a few belongings about!”
But there was nothing at all to be seen, and, as far as the boys could see, no way of getting out of the “waterfall cave,” as they called it.
They wandered round, looking for some outlet — but the water seemed to have found the only outlet — the tunnel down which it rushed after falling on to the channelled floor of the cave.
The boys went back to the water and gazed at it. Jack saw that through hundreds of years the waterfall had worn itself a bed or channel on the floor of the cave, and that only the surface water overflowed on to the ground where the boys stood. The channel took the main water, and it rushed off down a tunnel, and then was lost to sight in the darkness.
“I suppose the robbers couldn’t possibly have gone down that tunnel, could they?” said Paul suddenly. “There isn’t a ledge or anything they could walk on, is there, going beside that heaving water?”
The boys tried to see through the spray that was flung up by the falling water. Jack gave a shout.
“Yes — there is a ledge, and I believe we could get on to it. For goodness’ sake be careful not to fall into that churning water! We’d be carried away and drowned if so, it’s going at such a pace!”
The boy bent down, ran through the flying spray, and leapt on to a wet ledge beside the water, just inside the tunnel into which it disappeared. He nearly slipped and fell, but managed to right himself.
He flashed his torch into the tunnel and saw the amazing sight of the heaving, rushing water tearing away down the dark vault of the mountain tunnel. It was very weird, and the noise inside the tunnel was frightening.
Paul and Mike were soon beside Jack. He shouted into their ears. “We’d better go along here and see if it leads anywhere. I think this is the way the robbers must have gone with Ranni and Pilescu. Keep as far from the water as you can and don’t slip, whatever you do!”
The boys made their way with difficulty along the water-splashed tunnel. The water roared beside them in its hollowed-out channel. The noise was thunderous. Their feet were soon wet with the splashing of the strange river.
“The tunnel is widening out here,” shouted back Jack, after about an hour. “Our ledge is becoming almost a platform!”
So it was. After another minute or two the boys found themselves standing on such a broad ledge that when they crouched against the back of it, the spray from the river no longer reached them.
They rested there for a while. Paul was terribly tired by now. Mike looked at his watch. It was four o’clock in the morning! The sun would be up outside the mountain — but here it was as dark as night.
“I feel so sleepy,” said Paul, cuddling up against Mike. “I think we ought to have a good long rest.”
Jack got up and looked around the broad platform for a more comfortable resting-place. He gave a shout that quickly brought the others to him.
“Look,” said Jack, shining his torch on to a recess in the wall of the tunnel at the back of the platform. “This is where the robbers must sometimes rest before going on to wherever they live!”
