A most unearthly racket sounding awoke every one. If an earthquake had occurred it could hardly have created a greater noise. And the big frying pan proved that the supreme confidence which Lub had placed in its ability to jangle had not been in the least overdone; for it certainly played a fandango as it pitched over on the hard floor of the cabin, and danced some sort of jig, with other things adding their little mite to swell the chorus. Four fellows came tumbling out of their bunks as one. "Phil, oh! Phil, strike a light!" cried one. "Where's my gun?" growled X-Ray Tyson, thinking that in this way he must give fresh alarm to the bold intruder, whoever he might prove to be. "Phil, the thief has come down the chimney, just as I feared!" called Lub, who in the darkness hardly knew which way to look. As he managed to get his bearings to some degree he was sure he could detect a man on his hands and knees crawling over the floor. At the same time he heard a whining sound, as well as what seemed to be scratching; and it struck terror to the heart of poor Lub. He fancied that others were without, waiting for the first thief to open the door, in order that they too might rush in, and help make prisoners of the four Mountain Boys. Just then Lub to his great relief saw a tiny flame spring up close by. This he knew must be a match in the hand of Phil Bradley, who was meaning to light his lantern. To Lub it seemed an age before the flame was communicated to the wick, and yet it could only have been a comparatively few seconds, no longer than Phil would have taken under ordinary conditions. His hand did not tremble appreciably; and while in an undoubted hurry he went about his self appointed task with a deliberation that promised a successful result. Then came the snap as the globe was pressed into place. The room was no longer in darkness. It was possible to see; and with his heart feeling as though it were trying to climb up in his throat Lub fixed his eyes on the spot where he had discovered that moving, creeping object. What he saw thrilled him through and through, so that for the life of him Lub could not move, or even utter a sound above a whisper. Nor were the other boys much better off, to tell the truth, for they all stood there as though rooted firmly to the spot. CHAPTER VI GETTING RID OF AN INTRUDER "Whoo! it's a bear!" yelped Lub, who looked as though his eyes were trying to pop out of his head. "Tell me, am I seeing things? Is this a wild dream, or am I gazing on a real, live, woolly bear?" cried X-Ray Tyson. Just then, as though suspecting that the clustered boys had evil designs on him, the small black bear actually growled, and showed its white teeth. "Here, keep back, you!" exclaimed Ethan; "we haven't lost any bear that we know about. Where'd you come from anyhow, and what d'ye want here?" "Ethan--don't you see, he came down the chimney!" gasped Lub.
