Just in time did Bob whirl in his tracks and fire his gun, almost in the faces of the onrushing group of maddened animals, and this action caused them to veer, so that they passed by without doing injury. "Oh! what a narrow escape!" cried Sandy, who had been almost paralyzed by the nature of the sudden peril confronting them. And now they saw all manner of frightened animals speeding away as fast as their legs could carry them. Besides, a flock of wild turkeys sprang up with a furious whirring of wings, and were gone like magic. Partridges sailed past the two boys in coveys. Here a pair of red foxes fairly flashed by, making incredible speed. Everything seemed capable of getting out of the way of those greedy flames save the two young pioneers. It appeared at times to poor, impatient Sandy that they were having one of those ugly nightmares, where one's feet are glued to the ground, and all the while the peril plunges along toward the wretched dreamer. "If we could only find a cave of any kind, it might keep us from getting scorched!" ventured Sandy presently, though he found he had to raise his voice considerably in order to be heard, so loud were those terrible noises that accompanied the rush of the fire wall. "But there are none around here, for I have been looking," answered Bob. "I saw lots a while ago, all sorts of queer holes in the ground and rocks. Oh! don't I wish we could find just one now!" cried the other. "Ha! here is what we are looking for, a hollow tree trunk!" Bob shouted, just at that moment, when hope had well nigh deserted poor Sandy. He dragged his brother over to the left, to where a rather large oak stood. "I just happened to look back, and saw the opening. The tree is hollow, brother! Push in, and try to close the opening all you can, so as to keep out the smoke!" Almost before he knew what Bob was about, Sandy found himself shoved through the rather narrow opening. "But it is not big enough for two! We can never stay here, Bob. Help me out!" for all at once the lad realized what his brother meant to do. Did he not know only too well the self-sacrificing devotion of Bob? The other meant that he should find possible safety in this snug retreat, while he took chances of discovering another hole in which to burrow. And if the fire rushed down upon him before this discovery could be made, what then? There would be only one of them go back to the new cabin in the clearing that looked out on the clear waters of the Ohio. "Stay where you are, and do not move, on your life, or you will ruin all! There is another hollow tree for me! Remember mother, and do what I say!" And, giving Sandy a last push, Bob darted away.
