goes wandering out in the night!"

"Oh, Stephen is usually a pretty level-headed sort of a fellow!" replied
Mr. Buck. "He is out of humor just now because he has always denied that
he visited the mine during his two weeks of absence. He is one of the
men who dislike very much to be caught in an error of any kind."

"So he knows where the money is?" asked Sandy.

"He says he can find it if he can secure the services of Canfield, the
caretaker. He remembers now of getting in the mine, and of hearing
footsteps in the darkness. His impression at that time was that robbers
had followed him in, so he unloaded the banknotes in a small chamber
which he is now able to describe accurately but which he cannot, of
course, find."

"Was the money hidden on this level?" asked Sandy.

"Yes, on this level."

"In this gangway?"

"He thinks it was hidden here."

"Right about here, or further on?"

"Why," was the answer, "he seems to remember something about Tunnel Six.
He thinks he hid the money there! As soon as he finds Canfield, the
caretaker will probably be able to tell him exactly how Tunnel Six
looks."

"It looks all in a mess right now! I can tell you that," grinned Sandy.

"What do you mean by that?"

"I mean that there's been doings here!" replied Sandy.

"Are there really robbers in there?"

"Sure, there are robbers in there!"

"Then perhaps we'd better bring in a squad of deputies."

"If you'll just let us boys alone," Sandy said, "we'll bring the money
out if it's anywhere in the mine, but if this man Carson goes to butting
in at this time, he'll have to dig out his own money. He won't believe
there's any robbers in there, and he wants to fire me out of the mine,
so I guess we'd better let him go his own gait a little while."

"He'll do that anyhow no matter what you say!" replied Mr. Buck.

"Look here!" shouted Carson, starting forward, with his stomach out and
his fat shoulders thrown back, "what's all this conversation about? Why
don't some one go up and get Canfield, and why isn't that young rowdy
thrown out of the mine? I won't have him in here!"

"Say," Sandy broke in, "Mr. Buck says that you're looking for Tunnel
Six. If you are, I can show you right where it is!"

"Do so, then!" shouted Carson.

"Go straight ahead," Sandy directed, "and when the robbers begin to
shoot, you command them to throw down their weapons in the name of the
law. They'll probably do it, all right, if you tell them to,
