It was always a matter of some concern to the early pioneers, this keeping their rifles or muskets in condition for immediate use. The powder was apt to be shaken from the pan, or the flint in the hammer dislodged just enough to keep it from striking fairly, and sending out the important spark, which was absolutely necessary in order that the weapon be discharged. And hence, under the most intense excitement, hunters were wont to keep a watchful eye upon their guns in order that they might not fail. Both boys scrambled up the tree. The limbs were low, and fashioned just right for a quick ascent, and, as the hole which had caught the eye of Roger was not more than twenty feet from the ground, they were beside it in an exceedingly short space of time. But it might be noticed that neither seemed in any great haste to enter the gaping aperture that frowned so darkly before them. They could easily tell that it was a bear's den from the odor that greeted them, such as may always be detected where wild animals have their lodging; but even stout-hearted Roger would have braved the wrath of the coming deluge rather than drop down upon a savage bear. "Do you think he's in, right now, Dick?" he questioned. "I don't know. You see there was no time to examine the tracks below, and see whether the last ones headed in, or out. But we'll soon learn that. Fire your gun as straight down into the stump as you can, Roger; while I keep mine ready to give him a shot if he comes out." "A good idea, Dick; and here goes!" Roger pushed his long rifle into the hole as well as he could, and, aiming downward, pulled the trigger. The roar that followed was terrific in that confined space, and Roger hastily dragged his gun out, preparing to reload. He had in his early years been taught the first principle among hunters, that an empty gun is worse than none at all. Dick was waiting, ready to send a bullet into the head of Bruin, did he but make his appearance; but, as nothing followed the report of his cousin's rifle, he bent forward to look once more into the black aperture. "Not at home, is he, Dick; or do you think I could have been lucky enough to have killed him by a chance shot?" demanded Roger, hopefully. "Oh! no danger of that," replied the other, laughingly. "It's an empty den that we've run across, and the sooner we crawl inside the better." "Yes," said Roger, "I felt a big splash of rain on my face then. But how far down do you think the hole goes, Dick? I hope not all the way to the roots of the old tree. How could we climb up again; and what a tumble it would be if we let go and dropped." For answer Dick dropped a piece of heavy bark into the opening, and bent his ear in an endeavor to tell from the sound just about how far it had to fall.
