It startled her, and she didn't know why. A companion abruptly freezing in his path, his muscles inert, and his eyes filling with speculations is always startling. When this occurs, it means simply that a thought so compelling and engrossing that even the half-unconscious physical functions, such as walking, cannot continue, has come into his mind. And it is part of the old creed of self-preservation to dislike greatly to be left out on any such thought as this. If danger is present, the sooner it is identified the better.

"What is it?" she demanded.

He turned to her, curiously intent. "How many shells have you in that pistol?"

She took one breath and answered him. "It holds five, and I shot twice. I haven't any others."

"And I don't suppose it ever occurred to you to carry extra ones in your pocket?"

"Father is always telling me to—and several times I have. But I'd shoot them away at target practice and forget to take any more. There was never any danger—except that night with a cougar. I did intend to—but what does it matter now?"

"We're a couple of wise ones, going after that wolf with only three shots to our name. Of course by himself he's harmless—but he's likely enough to lead us straight toward the pack. And Snowbird—I didn't like his looks. He's too gaunt, and he's too hungry—and I haven't a bit of doubt he waited in that brush for us to come, intending to attack us—and lost his nerve the last thing. That shows he's desperate. I don't like him, and I wouldn't like his pack. And a whole pack might not lose its nerve."

"Then you think we'd better turn back?"

"Yes, I do, and not come out any more without a whole pocket of shells. I'm going to carry my rifle, too, just as Lennox has always advised. He's only got a flesh-wound. You saw what you did with two cartridges—got in one flesh-wound. Three of 'em against a pack wouldn't be a great deal of aid. I don't mean to say you can't shoot, but a jumping, lively wolf is worse than a bird in the air. We've gone over three miles; and he'd lead us ten miles farther—even if he didn't go to the pack. Let's go back."

"If you say so. But I don't think there's the least bit of danger. We can always climb a tree."
