This time Frank did not take off any of his outer clothing in order to protect the torch. He had noted that the old miner had two lanterns, and he expected to borrow one, if necessary.

Of course his torch was snuffed out while the furious blast swept by. Bob noted that each successive outbreak tried to beat the record, and he was wondering just when the limit of endurance might be reached.

The old miner, after the roar had subsided, offered the two boys his hand.

"How are ye, young Haywood?" he asked, recognizing Frank. "I heard about what you done for my little gal here, Inez Lopez, whose father was once a cowboy on the Circle ranch, and lost his life in a fight with some of his countrymen when they quarreled. I'm glad to see you. Found a nice little pocket here a year or so back. Kept it on the quiet; and the gal, playing the part of a boy, has been fetchin' me supplies once in two months, an' takin' away the dust I winnowed. Pocket's played out now, but I reckons as how I've got plenty. 'Sides, I just don't like the way things is agoin' here. That spoutin' geyser that rises up inside the old mountain every once in a while acts like it meant to break loose. Never saw it carry on that bad before; and we're just ready to cut and run, leavin' most of the truck behind. What brings ye here, Frank?"

So Frank had to explain in a few words, while the old miner looked admiringly at the boys, and grinned.

"I admire your nerve, young fellers," he declared, at the conclusion of the explanation. "And, Frank, ye guessed the true facts, blessed if ye didn't! I got onto the same by accident. Fell in through a hole, and just had to creep along this passage to the end. Then havin' guessed what made the roar, I wondered if so be I could find any stuff in here. So I took a lot of wood along, and made my discovery."

"And you say you're bound out now?" asked Frank.

"That's what we are, little Lopez and me; and we can't get to the open any too soon, either, to please both of us," Smith replied, shouldering his pack.

"Oh! say, Mr. Smith," cried Bob, "have you lost a pet that wears a collar?"

"Meanin' my pet painter, Nero, I take it," replied the miner. "I raised him up from a cub, and he's as fond of me as my dog. But he's gone somewhar. We ain't seen him for hours, and like as not the critter knowed it was gettin' dangerous in here. Trust animal sense for that. But wait till this next whoop gets by, and then we'll make for the door. Here's hopin' we'll all be smart enough to get to the open. Bend your backs to the wind, boys; ye wont feel it so much then," and all of them carried out his instructions as, with a rapidly rising roar, the spouting geyser that played in the heart of Thunder Mountain again started to break loose.
