"Boys," Canfield called. "Boys!"

"Will!" yelled Sandy.

"I guess they're going to bust up the whole combination!" declared Will rather sourly. "I wish I had them by the neck!"

"They may have important news," suggested Elmer. "Anyway, we'll have to turn on our lights and meet them. If we don't, they'll keep on yelling all down the gangway!"

Canfield and the two boys came up as soon as Elmer showed a light, and stood for a moment looking cautiously about.

"I don't think you boys ought to go any further into the mine!" Canfield exclaimed, breathing heavily from the long chase down the passage. "I have just received word that two of the most desperate hold-up men in the country have taken refuge here. There's no knowing how they got over to the mine, but it is a sure thing that they did get here, for a couple of breaker boys saw them climbing into the breaker."

"What time was this?" asked Will.

"Oh, I don't know," replied Canfield. "The matter was reported to me early this morning. I couldn't find you before, or you should have had the news sooner. It isn't safe for you to go into the mine!"

"Your information," grinned Will, "comes a little bit late, but it's all right, just the same! Ventner is in there, and there are two men with, him. It's a mystery how they made their way in without being discovered, but it seems that they did so."

"What are you going to do?" asked Canfield.
