"If it comes to the worst we may have to take to a tree just as the Indian brave has done," Dick told him, "and then start to work killing them off as fast as we can load and fire. Now, are you ready to do a lot of yelling?" "Just try me, that's all, Dick!" "Come on, then, with me!" With the words Dick sprang boldly forth from his concealment, with his cousin alongside. Both of them started to make the woods ring with their strong young voices, and when two healthy boys yell and whoop they can produce a tremendous volume of sound! Some of those predatory wolves must have conceived the idea that a whole company of the strange two-legged foes was rushing toward them, judging from the hasty manner of their exit from the scene. Others, however, either more bold or hungry, half crouched and, snarling, showed their white teeth in a vicious manner. Evidently these leaders of the pack were not as yet quite convinced that the game had gone against them, despite all the noise made by the oncoming boys. On seeing this, Dick and Roger tried to shout louder than ever, while they waved their arms in the most frantic manner. It devolved upon Dick to decide whether or not they should keep on in this fashion until they came to close quarters with the wolves that lingered, loth to give up their chance of a dinner. Rushing forward at this rate, they would be on the scene in half a dozen seconds, and might find the ugly beasts springing up at their throats. Never before had the boys seen wolves acting in this manner, for as a rule their nature is cowardly. There was nothing for it but to fall back upon their guns for the finishing stroke, and so Dick gave the word. "We must shoot, Roger--take that big fellow in front!" he gasped, for he was by this time fairly out of breath after all those strenuous exertions of running, thrashing his arms, and shouting at the top of his voice. Accordingly both of them halted just long enough to throw their long-barreled rifles to their shoulders, and glance along the sights. They could actually hear the savage snarls of the defiant pack. Roger, always a bit faster than his companion, was the first to fire, and with the crash of his gun the big leader of the pack sprang upward, only to fall back again with his legs kicking. Dick's gun spoke fast on the heels of the first report, and he, too, succeeded in knocking over the beast his quick eye had selected. Then with renewed shouts, Dick and Roger once more started forward, but there was a hasty scurrying of gray bodies, and presently not a wolf remained in sight save the pair that had gone down before the deadly fire of the guns.
