I had hoped that the strange thunder of the rifles would send them flying—but no. They all stopped again for a moment, and then, maddened seemingly at the sight of the broken-backed wolf dragging itself about and screeching with pain—poor beast—they all fell upon the unfortunate creature and worried it to death. Then, with yells of rage, on they came again.

The pause had given us time to re-load. Dick and Pedro, quicker than I, fired a second shot, and once more two wolves fell writhing among the stones. The next moment we were surrounded, and for a minute or two after that I was too much engaged myself to note what the others were doing.

A gaunt, long-legged wolf sprang up on the rock within three feet of me. I fired my rifle into his chest. Another, close beside him, was within an ace of scrambling up when I hit him across the side of his head a fearful crack with the empty rifle-barrel and knocked him off again. Then, seeing a third with his feet on top of the rock, his head thrown back in his straining efforts to get up, I sprang to that side, kicked the beast under his chin and knocked him down.

Meanwhile my companions had been similarly engaged and similarly successful. Pedro in particular, having dropped his bow and taken in one hand the short-handled ax he always carried with him, while in the other he held his big sheath-knife, had laid about him to such effect that he had put four of the enemy out of the fight—two of them permanently.

Dick was the only one who had received any damage, and that was to his clothes and not to himself. His rifle being empty, he had used it to push back the wolves as they jumped up. In doing so he had stepped too near the edge of the rock, and one of the watchful beasts, springing up at that moment, had caught the leg of his trousers with its teeth, tearing it from end to end and coming dangerously near to pulling my partner down. Pedro, however, quick as a flash, had delivered a back-handed "swipe" with his ax at the wolf's neck, nearly cutting off its head, and Dick was saved. It was an unpleasantly close thing, though.

It was a short, sharp tussle, and at the end of it nine of the sixteen wolves lay scattered about the bed of the ravine, dead or helpless. This seemed to take the fight out of the remaining seven—as well it might—who retreated down the arroyo, turning at the corner and looking back at us with their lips drawn up and their teeth showing, seeming to convey a threat, as though they would say, "Your turn this time—but just you wait a bit."

Such unexpected fierceness and such determination on the part of the wolves—by daylight, too—scared me rather; Dick also, I noted, looked pretty sober, as, turning to the Mexican, he said:

"You were right, Pedro: these wolves are dangerous—a good deal more so than I had supposed. Our chances would have been pretty slim if we hadn't had this rock so handy. If this sort of thing is going to happen at any time, day or night, it will add very much to the difficulty of the work up here. We shall have to be continuously on the lookout; it won't do to separate; and wherever we are at work, we shall have to prepare a place of refuge near at hand. I don't like it. I've seen wolves by the hundred, but I never saw any before so savage and so persistent as these. I tell you, I don't half like it."

"And I don't either," said I, glad to find that I was not the only one to feel uneasy. "Did you notice, Dick, how thin they all were? I've often heard the expression, 'gaunt as a wolf,' and now I know what it means. They seemed half-starved."

"That is it, senor," remarked Pedro. "The wolves up here are very many—too many for the space they have. Here they are, the cañons all round them, they cannot get away. All the time they are half-starved, all the time they hunt for food, all the time they are dangerous. Often in winter they eat each other. It is well if we move away from here. Pretty soon there will come another pack to eat up these dead ones."
