"I'm pretty certain that it connects with Tunnel Six," replied the caretaker. "But you mustn't show your light when you approach the old shaft," he went on, "because if it does connect with the chamber we seek, and the chamber in turn connects with the north pa.s.sage, the robbers will see what we're doing."

"That's a valuable suggestion!" replied Will.

"I'll go on ahead," Canfield continued, "and find the old shaft. Then you can follow on with the rope, and one of you boys can drop down and see what can be discovered."

"It's dollars to apples," chuckled d.i.c.k, as the boys trailed along after the caretaker, "that we find the three kids trussed up like a lot of hens ready for the market in the chamber where you came so near getting wet. I hope we do, at any rate!"

"There's one thing we overlooked," Will said as Canfield whispered to them that he had found the deserted shaft, "and that is this: We should have directed the boys in the gangway to have attracted the attention of the outlaws by a little pistol practice while we are communicating with our friends. They may be all packed away in the chamber together."

"Yes, we should have attended to that," replied d.i.c.k. "Perhaps I'd better go back now and tell them to get busy with their automatics."

"We may as well investigate the situation here first," the other answered.

The boys heard the caretaker creeping about in the darkness, and presently a piece of shale or coal was heard rattling down the old shaft.

"We'll have to get that blundering caretaker away from there," whispered Will. "If we don't, he'll notify the hold-up men that we're getting ready to do something! I've heard that about three-fourths of the people in the world object to doing anything unless they can take a bra.s.s band along, and I guess it's true."

"Say," Canfield whispered, calling back to the lads, "when that stone dropped down, I heard something that sounded like a paddle slapping down on the water. That room can't be wet yet, can it?"

"The Beaver call!" whispered Will.

"Right you are!" replied d.i.c.k. "The boys are there, all right!"

"Now the next thing to do is to find out if those highwaymen are watching them," declared Will.

"I'll tell you that in a minute," d.i.c.k whispered.

As the boy spoke, he pa.s.sed one end of the rope to Canfield.

"Hang on to it, whatever takes place!" he whispered, "and I'll drop down and see what's going on."

"You must be very careful," warned Canfield.

"That's all right," answered d.i.c.k, "but we can't stand here all day figuring out precautions. We've got to know right off whether there's anyone in that chamber watching the boys!"

"What a joke it would be to put on a ghost in Tunnel Six!" laughed Will, in a decidedly cheerful frame of mind, now that rescue seemed so near.

"Don't try any foolishness!" advised Canfield. "Let's rescue the boys if possible and make our way out of this horrible place."

Will crawled to the edge of the shaft with d.i.c.k and whispered as he lowered him into the dark opening below:

"Remember," he said, "that Ventner may have discovered the money. If so, we must secure it before we leave the place! It will be just like him to stow the bank notes away in some chamber like the one you are about to enter. When you strike bottom, if there is no one in sight except the boys, turn on your searchlight and take a good look over the interior of the chamber.

"We were in there not so very long ago, but at that time we weren't thinking of making a search there for hidden money. You'll have to use your own judgment about turning on the light, of course. The outlaws may be out in the gangway, some distance from the entrance to the chamber, or they may be within six feet of where the boys are held as prisoners."

"Tommy ought to be able to tell me the minute I strike the heap of shale whether the outlaws are close by or not!" d.i.c.k suggested.

"Of course!" answered Will, "if he knows. If the men are not in sight, and he doesn't know where they are, you'll simply have to take chances.

If you get caught in there, you'll have to shoot, and shoot quick!"

d.i.c.k, dropped down into the old shaft and directly the anxious watchers above heard the rattle of shale as it dropped from the pyramid under the opening. Will, still clinging to the rope, lay on his stomach and peered downward, watching with all anxiety for some show of light, or some sound which might indicate the situation below.

Directly Will felt a soft, steady pull at the rope, and knew that one of the boys was ready to be a.s.sisted to the top.

d.i.c.k came up first, chuckling as he landed on the edge of the break in the rock, and was immediately followed by Jimmie.

"Where's Tommy and George?" asked Will in a whisper.

"They're down there looking for the money!"

"Looking for the money in the darkness?"

"Sure!" was the reply. "You see," he went on, "those ginks tied us up good and tight, and then threw the money around promiscuous like!"

"So the money is there?" asked Will.

The news seemed too good to be true!

"It was there when we were first thrown into the chamber," replied Jimmie, "but I have an idea that Ventner sneaked in and removed it so as to prevent his mates getting any share."

A light flashed out from below, followed immediately by a pistol shot!

CHAPTER XX

SANDY IS DISCHARGED

Elmer and Sandy, guarding the gangway variously called the North section and Tunnel Six, presently heard voices coming from the direction of the shaft, and the latter moved back a few paces in order to inspect the new-comers. In a moment he saw three rather pompous looking men approaching him, their footsteps being directed by a man clothed as a miner.

"Here, boy!" shouted one of the pompous men. "Can you tell me where Canfield, the caretaker of this mine, may be found?"

"He's up on the next level," replied Sandy.

"I was told he was down here," growled the speaker, who was very short and fat, and very much out of breath.

"He was here a little while ago," answered Sandy.

"What's the meaning of this show of firearms?" demanded the fat man, after glancing disdainfully at the automatic in the boy's hand.

"We've got three robbers cooped up in the mine," replied Sandy.

"That's the old, old story!" exclaimed the fat man. "I don't know that I ever knew of a mine that wasn't haunted, either by ghosts or robbers!

Mysteries seem to breed in coal mines!"

Sandy walked back to the place where he had left Elmer, and the three men and their guide followed him. When Elmer caught a view of the fat man's face and figure, he gave a sharp pull at Sandy's sleeve.
