Filling his cob pipe with cut-plug, Joe sat looking away over space toward our hobbled horses and then said:

"Old man, I reckon you remember all about the Black Prince robbery. I don't forget you were the first man that came to the cooler to see me while I was doing time as a suspect. Well, coming right down to the point, I had the dust all the time! And the working out of the mystery would be rather interesting reading if it was written up, and, as you are such an accomplished liar, I wouldn't be surprised if you made it the base-line of one of them yarns of yourn -- only, mind you, don't go too far with it, for it's as curious as a lie itself. I would not try to improve on it, if I was you. I'll tell it to you as it was.

"About four days before the robbery, I was introduced to Rachel Rokesby, daughter of one of the partners in the Black Prince. I met her, in what seemed to be a casual way, at Mother Cameron's hash-foundry, but I found out, a long time afterward, that she had worked for two weeks to bring about the introduction.

"I don't know as you remember seeing her, but she was a quiet, retiring, well-educated, rosy-cheeked English girl -- impressed you right away as being the pure, unrefined article, about twenty-two karat. She "chinned" me about an hour, that evening, and just cut a cameo of her pretty face right on my old heart.

"Well, course I saw her home, and tried my best to be interesting, but if a fellow ever in his natural life becomes a double-barreled jackass, it's just immediately after he falls in love. Why, he ain't as interesting as the unlettered side of an ore-sack.

"But we got on amazing well; the girl did most of the talking and along toward the last, mentioned that she was in great trouble -- of course I wa'n't interested in that at all. I liked to have broken my neck in getting her to tell me at once if I couldn't do something to help her, say, for instance, move Raton mountain up agin Pike's Peak.

"I went home that night, promising to call on her the next trip, not to let any one know I was coming, not to tell anybody I had been there, not for worlds to repeat or intimate what she told me, and she would tell me her trouble from start to finish, and then I could help her, if I wanted to. Well, I wanted to, bad.

"'Well," says she, finally, "it is not generally known, in fact, isn't known at all, that the Black Prince is a paying placer, and that papa and Mr. Sanson have been taking out lots of gold for some time. They have over fifty pounds of gold-dust and nuggets hidden under the floor of the old mill.'

"'Well,' says I, 'that hadn't ought to worry you so.'

"'But that isn't all the story,' she continued; 'we have discovered a plot on the part of Mr. Sanson to rob papa of the gold and burn the mill and sluice-boxes, to hide the crime. You will find that every tough in town is his friend, because he buys whisky for them, and they all dislike papa. If he carried out his plan, we would have no redress whatever; all the justices in town can be bribed. The plan is to take the gold, burn the mill, and then accuse papa of the crime. Now, can't you help me to fool that old villain of a Sanson, and put papa's half of the money in a safe place?'

"I thought quite a while before I answered; it seemed strange to me that the case should be as she stated, and I half feared I might be made a cat's-paw and get into trouble, but the girl looked at me so trustingly with her blue eyes and added:

"'I am afraid that I am the cause of all the trouble, too. Papa and Sanson got along well until I refused to marry him; after that, the row began -- I hate him. He said I would have to marry him before he was done with me -- but I won't!'

"'You bet you won't, darling,' says I, before I thought. 'Pardon me, Miss Rokesby, but if there is any marrying done around here, I want a hand in the game myself.'

"She blushed deeply, looked at the toe of her shoe a minute, and said:

"'I'm only eighteen, and am too young to think of marrying. Suppose we don't talk of that until we get out of the present difficulties.'

"'Sensible idea,' says I. 'But when we are out, suppose you and I have a talk on that subject.'

"She looked at the toe of her shoe for a minute again, turned red and white around the gills, looked up at me, shyly at first, then fully and fairly, stretched out her hand and said:

"'Yes; if you care to.'

"Course, I didn't care, or nothing -- no more than a man cares for his head.

"I guess that was about a half engagement, anyhow, it's the only one we ever had. She said it would be ruinous to our plans if I was seen with her then or afterward; and agreed to leave a note at the house for me by next trip, telling me her plan -- which she should talk over with her father.

"A couple of days later I got in from a round trip and made a dive for the boarding-house.

"'Any mail for me, mother?' I asked old Mrs. Cameron.

"'No, young man; I'm sorry to say there ain't'

"'I was anxious to hear from home.'

"'Too bad; but maybe it'll come to-morrow.'

"I was up to fever heat, but could do nothing but wait. I went to bed late, and, raising up my pillow to put my watch under it, I found a note; it read:

"'Midnight, July 17.

"'Dear Joe:

"'Just thought of that rule for changing counter-balance you wanted. There has always been a miscalculation about the weight of counter-balance; they are universally too heavy. The weights are in pieces; take out two pieces; this treatment would even improve a mule sweep. When once out, pieces should be changed or placed where careless or malicious persons cannot get hold of them and replace them. All is well; hope you are the same; will see you some time soon.

"'Jack.'

"Here was apparently a fool letter from one young railroader to another, but I knew well enough that it was from Rachel and meant something.

"I noticed that it was dated the next night; then I commenced to see, and in a few minutes my instructions were plain. The old five-stamp mill was driven by a mule, who wandered aimlessly around a never-ending circle at the end of a long, wooden sweep; this pole extended past the post of the mill a few feet, and had on the short end a box of stones as a counter-weight. I would find two packages of gold there at midnight of July 17.

"I was running one of those old Pittsburgh hogs then, and she had to have her throttle ground the next day, but it was more than likely that she would be ready to go out at 8:30 on her turn; but I arranged to have it happen that the stand-pipe yoke should be broken in putting it up, so that another engine would have to be fired up, and I would lay in.
