"It isn't that that bothers me at all, Bob. But Polly has no sense of fear, and I think they may have found an exit at the other end, so Polly is coming around that way. It is a hazardous thing to do, in this storm!" said Anne. "Anne, can't you try to squeeze in there and see what has happened?" asked Barbara. Anne looked at her without saying a word, so Barbara thought she hesitated on account of leaving her alone in the cave. "I won't mind staying alone for a little time. I'll watch the fires and see that the horses do not get away!" said Barbara. "Really!" was all Anne said, as she turned to place another pine knot on the fire. But the tone silenced Barbara, who had food for thought thereafter. Meanwhile Polly and Eleanor had crawled into the aperture, and by dint of squirming and twisting through the passage, found that only the section nearest the cave was of soft debris. It gradually widened as they advanced and Polly distinctly felt a current of cold air blowing in her face. After creeping along for some distance without finding an outlet, Eleanor pulled on Polly's foot to attract her attention. "Let's go back, Poll. No use hunting down in the bowels of Grizzly Slide." "Nolla, the smoke of the torch blows harder than at first, and there is enough air to waft it backwards, so there will be an opening at the end, I am sure. That is what I must know for certain." "All right, lead on! I'll be with you at the death!" Polly chuckled at Eleanor's loyalty and crept on. Finally Eleanor rugged again at her feet and shouted: "Hey, Polly! Aren't we most through to China? Let me know the moment you get the first peep at a pig-tail, as I have to brush the cobwebs from my Chinese!" Polly laughed at the girl who made merry of a journey that would have staggered an older person. Finally, however, the tunnel widened so that both girls could advance comfortably and then, suddenly, the flame of the torch and the smoke ceased to blow into their faces, for they had come out into an open space. "We're here!" laughed Polly, trying to stand up and giving her head a smart rap against the overhanging rock. "'We're here!' For goodness' sake, tell me where?" cried Eleanor, thrusting her torch ahead so that it was almost snuffed out against Polly's shoes. "Gracious me, Nolla! Don't burn my soles!" cried Polly, managing to stand upright and hold aloft her torch. "Ha, that's good! Don't burn your soul!" teased Eleanor. But the moment the girls saw where they were, not another word was uttered, for they found themselves in a vault-like cave somewhat smaller than the entrance cave, but having no "fingers" or outside opening. The dome and sides were rocky, but everywhere, embedded in the rock, myriad points of light reflected as the flare of the torch lit up the place uncertainly.
