“This evening,”replied Joe. “It was this evening, wasn’t it, Phil?”

“Yes,”I replied. “He was to quit at five this evening, and his intention then was to come down here next day and make this place his base of operations.”

“Then the thing to do,”said Joe, “is for me to ride up there this morning—I started to go yesterday, you know, Peter—and catch Tom up at the mine at noon. When he hears of our discovery, I’ve not a doubt but that he will pack up and come back with me this evening, so as to get a start first thing to-morrow.”

“I expect he will,”said I. “And while you are up there, Joe, you can see Yetmore and give him your information about those cart-tracks.”

“What do you mean?”asked Peter. “Information about what cart-tracks?”

“Oh, you haven’t heard of it, of course,”said I; and forthwith I explained to him all about the ore-theft, and how we suspected that the thief was in hiding somewhere in the foot-hills. Peter listened attentively, and then asked:

“Are you sure there was only one of them?”

“Well, that’s the general supposition,”I replied. “Why?”

“I thought there might be a pair of them, that’s all. I’ll tell you an odd thing that happened only the day before yesterday, which may or may not have a bearing on the case. When I got home about dusk that evening, I found that some one had broken into my house and had stolen a hind-quarter of elk, a box of matches, a frying-pan, and—of all queer things to select—a bear-trap. What on earth any one can want with a bear-trap at this season of the year, I can’t think, when there is hardly a bear out of his winter-quarters yet; and if he was he’d be as thin as a rail. I found the fellow’s tracks easily enough—tall man—big feet—long stride—and trailed them down the gulch to a point where another man had been sitting on a rock waiting for him. This other man’s track was peculiar: he was lame—stepped short with his right foot, and the foot itself was out of shape. Their trail went on down the hill towards the mesa, but it was then too dark to follow it, and I was going off to take it up again next morning when that slide came down and changed my programme.”
