"I've got the light. What is the rule?"
"Always—no matter where you are in any of them caves, take the way to the right. Never take a gallery to the left, goin' in either or any direction. It's a rule that holds good in them caves. It's a sort of way that nature provided so's you could find your way through there; and I happened to discover what it was."
"It all sounds very simple and easy."
"And it is, if you've got the pluck and the sand. But it's a ticklish place. There is a good many places in there that I ain't never explored, and don't want to; and it's safe to bet that the hoboes ain't done it, neither. I reckon, mister, that that's about all I kin show you—hold on, though!"
"What now?"
"Well, there's one place up there which it might be handy for you to know about, and I don't think anybody but me knows about it, either."
"What is that?"
"Well, you might find occasion to want to hide yourself away while you are in there."
"That is more than likely, Bill."
"Well, just arter you pass through the hole that is under the Dog's Nose, and about twenty rods from there, you'll find a place where there is a bowlder sort of set into the rocks. You won't notice it unless you look for it, but it is there. Under it you'll find a small stone wedged fast. If you pull out that small stone, and then push on the big rock, it'll swing around like it was on a pivot, and you kin step inside the hole it leaves, and close up the door after you. You'll find an interestin' place in there, too, if you ever have occasion to use it, mister; and nobody will find you there, either."
