"Yes?" said the Kentucky lad, eagerly, suspecting what was coming.
"And I can see signs of light at the curve," Frank went on.
"Hurrah! Everything seems to be coming out just as you figured, Frank. When I get back to the ranch I'm going to write to the president, proposing that he put you in charge of the weather bureau. Every old farmer will know then when to look out for storms."
"Well, we may be in for one now," observed Frank, dryly.
"Look here, you mean something by that remark," Bob cried. "Do you expect we're going to have a peck of trouble with these miners?"
"I don't know. It all depends on what sort of men they are," Frank replied.
"But we wont let 'em drive us out of here until we know all about that geyser, if there is such a thing; will we, Frank?"
"Well, I reckon it won't take a great deal of driving to get both of us out; but of course I do hope we'll learn something about the real cause of all this awful racket. Are you ready to turn the bend, Bob?"
"Sure," and the Kentucky boy ranged alongside his chum, by this movement plainly indicating that he did not mean to let Frank take any more risk than he himself was ready and willing to assume.
No sooner had the two saddle boys turned the bend in the passage than they saw a singular spectacle.
