George made the camp and cooked the supper, and when they had satisfied their appetites, the former laid down on his blanket in front of the fire with his saddle for a pillow, and listened to Zeke, who talked and smoked incessantly. Their work for the day was over now. The cattle were always brought close in to camp at dark, the horses and mule were staked out, and the campers went to bed at an early hour. If they awoke during the night, they replenished the fire with some of the fuel that was always kept close at hand, and walked around the herd to see if there were any restless ones in it who felt inclined to stray away. George performed this necessary duty twice on this particular night making the first round about twelve o’clock. To his surprise, he found the most of the cattle on their feet, and saw that some of them were exhibiting unmistakable signs of uneasiness and alarm. They stood snuffing the air eagerly, carrying their heads high and their ears thrown forward, and now and then they would walk a few steps out of the herd, lower their horns and paw the ground as if challenging the object that had excited them, whatever it was, to come out and give them battle. The rest of the cattle were lying down, chewing their cuds contentedly, and apparently not at all disturbed by the antics of their nervous companions. George threw himself flat upon the ground and swept his eyes around the horizon. In this position, he could distinctly see any object that might be approaching the camp (provided, of course, that it was taller than the grass) for it would be clearly outlined against the sky. But he could see nothing. He arose to his feet again and listened intently, but could hear nothing calculated to excite his alarm. The wolves which serenaded them every night were holding a concert a short distance away, and that made George believe that if there was any danger approaching, it was yet a long distance off; for he knew that the wolves would be the first to discover it, and that they would then bring their concert to a close and take to their heels. “There’s something up,” thought George, once more turning his eyes toward the cattle. Some of the uneasy ones, reassured by his presence, were walking about among their companions, as if they were looking for a good place to lie down, while the others remained in a defiant attitude and snuffed the air as before. “There’s something up,” repeated George, “and I have been expecting it. I have felt very nervous and timid for two or three days, and I don’t know how to account for it. If there is anybody within hearing or smelling distance who has no business here, I can find it out.”
