The sight was one that would have made the nerves of even an experienced hunter thrill with excitement; and we can imagine the effect it must have had upon Oscar, who had never seen anything like it before. He knew now where the leading buck came from so suddenly. He and the rest of the flock had been down to the valley to slake their thirst at the brook, and were now returning to their feeding-grounds. Probably the sheep the wolves had killed was a member of the same flock, which had been left behind by his companions. That he had not been attacked while in their company was speedily proved to Oscar’s entire satisfaction. The hunter did not shoot for two reasons. The newcomers, when they mounted the bluff, stepped up between him and the leading buck, completely concealing him from view; and even if he could have seen him, it was by no means certain that Oscar would have brought him down, for there were others in the flock that were just as large as he was, and whose horns were just as finely developed. It was hard to choose among so many. While Oscar was running his eye over the flock, trying to make a selection, the big-horns ranged themselves in a half-circle on the edge of the plateau, and snorted and stamped their feet while they watched the wolves at their repast. The fierce animals evidently did not like the looks of things at all, for they stopped their quarrelling among themselves; and, keeping one eye on the sheep, growled savagely at them, while they made all haste to finish what was left of their breakfast. Matters stood thus for just about a minute, and then one of the sheep bounded forward with an angry snort; and, lowering his head, struck the nearest of the wolves a blow in the ribs that fairly lifted him off his feet. As quick as thought the gallant buck turned upon another; but, before he could strike him, the wolves closed upon him and pulled him to the ground. They did not have time, however, to inflict any serious injury upon him; for he was too promptly backed by every one of his companions. Rushing forward in a body, they closed upon the wolves from all sides; and Oscar was the amazed spectator of one of the strangest battles that any hunter ever witnessed. He was deeply interested in it, and so greatly bewildered, besides, that he entirely forgot that he had a loaded gun in his hands. For a few seconds the combatants were mixed up in the greatest confusion, and it was a wonder to Oscar that the bucks, in their terrific rushes, did not knock one another over; but they seemed to know just where to strike, and every charge they made was followed by a yelp of pain from some unlucky wolf.
