"Not much; only how does he come to know any of them? And why don't he take the Conant trail that's open and easy and not much longer? One man and a hawss. I don't see who he is or what he wants here."

"Probably a prospector," I suggested.

"Only one outfit of prospectors has ever been here, and they claimed there was no mineral-bearing rock in these parts."

We got back into our saddles with the mystery unsolved. To the Virginian it was a greater one, apparently, than to me; why should one have to account for every stray traveller in the mountains?

"That's queer, too," said the Virginian. He was now riding in front of me, and he stopped, looking down at the trail. "Don't you notice?"

It did not strike me.

"Why, he keeps walking beside his hawss; he don't get on him."

Now we, of course, had mounted at the beginning of the better trail after the steep rock, and that was quite half a mile back. Still, I had a natural explanation. "He's leading a packhorse. He's a poor trapper, and walks."
