"Oh, yes, I was going to tell you about that, wasn't I? Well, he was a hard case," continued the speaker. "Half Mexican, half white man—and all bad, he was. I made his acquaintance about ten years ago at Boisé City, and the first thing I heard of him was that he'd just killed a gambler—gambler was a hard case, so nobody cared much—and Jack skipped. Shortly after that he went to Denver and bullied the town. Oh, he was a regular 'bad man.' You know what a 'bad man' is, don't you?"

"Sure," said John. "Tough customer who knows he's tough and takes pride in it. They're always mighty quick with their guns, and dead shots. One of 'em shot a man in the arm, near our shack back in Bismarck, and mother tied it up. It was queer; the bullet went right through and it looked like a rose where it came out."

"Well," continued Abe, "Jack was a 'bad man,' and he didn't care who knew it. He had a shooting scrape in Denver and had to jump the town in pretty lively style. The sheriff's posse got after him, but he killed two of 'em and got off. After that every sheriff in the country was looking for him, so he turned outlaw and road agent near Virginia City, and held up Ben Halliday's stages till the vigilance committee hung some of his partners and got too hot on his trail. Not a thing more did I hear of him till he turned up about two years ago with this bunch of sheep of your father's. He had turned herder and driven 'em all the way in from Utah." Miller stopped to relight his pipe, for he had forgotten to keep it going in the interest of his tale. The boys were impatient at the least delay; the ruddy firelight lit up their faces and showed their eager interest.

"Your father had bought this ranch and put me in charge just a little while before Mexican Jack came along; I spotted him at once and he spotted me, but I didn't let on, for I knew he was all-fired quick with his gun and I wasn't looking for trouble. Of course he never went to town: it wasn't healthy for him there; and if he wanted anything he had to wait till somebody who was going in would get it for him. Even with such care, though, he knew it wasn't safe for him to stay in one place very long, so one day in spring he told me he was going to quit and move on. Don't you boys ever turn 'bad men,'" said Abe, with a laugh; "it don't pay. Brave as that poor chap was, he was fairly afraid of his shadow when he got to thinking of sheriffs' posses. One man isn't much good against the law, even out here. Well," he went on, "I went to town to get another man—it's thirty miles, so I stayed over night. Charley Boyd, who runs a liquor joint there, told me a young feller, an Englishman, he thought, had been in there several times asking about sheep. Charley said there might be some business in it, so I dropped in later.

"Boyd went up to a young chap who was sitting watching a faro game. 'Here's your man, Mr. Simmons,' said he. The stranger wanted to know all about the different bunches of sheep near there, so I told him and talked a good deal about one thing or another having to do with them. I remember I told him I was looking for a herder to take the place of a Mexican that was going to quit. Soon after that he left. I could not quite make him out, but it was plain enough he wasn't buying."

"What's all this got to do with Mexican Jack?" inquired Ben, who didn't see the drift of the narrative.

"If you wait a minute, I'll tell you." Abe was vexed at the thoughtless interruption, and Ben subsided, realizing that he had been rather foolish. "In the morning I packed my stuff on the led horse, mounted my own cayuse, and started out. I had just topped the rise near the shack when a bullet went by with a hum, and then another and another, so I chased back for cover to the other side. I dismounted, crawled up to the top, and looked over. There at the door sat Mexican Jack, six-shooter in hand. I couldn't understand why in the world he should shoot at me, so I rode over to look up Billy, the other herder, and find out what was up. He hadn't been to the shack since morning and knew nothing about it, so he left the sheep and we went down the coulie, which runs just below here, you know, till we got behind that clump of brush—perhaps you saw it. We peeked through pretty cautious, I can tell you. The Mexican was still there, but his body was all hunched up; he seemed drunk or asleep, for his six-shooter lay on the ground by his side.

"We covered him with our guns, for he was chained lightning with his shooting irons, and then yelled at him. He didn't answer or move an inch. We jumped out then, still keeping him covered, and walked slowly up, ready to riddle him if he should make a move with that deadly pistol hand of his. Once he quivered a bit and his right hand stirred toward his gun. I almost plunked him then, I was so nervous, but there was no other sign of wakefulness or life. We decided he must have gotten hold of some liquor somewhere, but when we got within about fifty feet of him Billy noticed a pool of blood at his side. Then we rushed forward—guns still ready, however—and just as we reached the steps he lurched forward and fell full on his face—dead!

"A couple of bullets had gone clean through him. We found out when we turned his body over to the authorities in town that Simmons, the young Englishman I had met, had come over to America a year before expressly to kill Mexican Jack, who had shot his brother in some quarrel. I had supplied the missing link of information, and he had gone early in the morning to our shack, where he had shot the Mexican twice. Jack evidently thought I had given him away purposely and tried to settle me."
