"Then let's have him. This cuttin' can't be so long but that we'll get all over it before sunset," Joe cried, as he wrenched the shovel handle from the iron work to serve as a weapon.

"I thought I heard somebody running in that direction when I first fell," Fred said, pointing toward the quarter in which it was reasonable to suppose the old shaft might be found.

Joe led the way, the others following close behind until, when half a mile had been traversed, they arrived at two slopes or inclined tunnels, running at right angles from the level.

"It won't do to pass these," Bill cried. "We'll take one, while the boys search out the other."

He darted into the right-hand opening as he spoke; but returned before Joe could join him, saying:

"That was a false cutting. It only runs a dozen yards, an' there's nothin' in it. Sam, you an' Fred look into the other one while we keep on."

The idea of coming upon Cale Billings while they were unarmed was not a pleasant idea for the boys; but they would have braved considerably greater danger rather than show signs of fear, and both obeyed promptly.

This slope ran at an inclination of nearly forty-five degrees for about fifty yards when it turned sharply to the right, terminating in a small chamber where the vein had probably came to an end.

As Sam and Fred entered the place a figure darted from one corner and attempted to rush past them; but the flight was checked very suddenly.

"Why it's Skip Miller!" Sam cried, as he lowered his lamp that the rays might fall upon the prisoner's face.
