decidedly crooked on the cards, but if we had known what it was, we couldn't very well have done anything to prevent it. There were only two of us men to their four; and, besides, there wasn't any time. The lantern-carrying man had barely reached the lower switch when we heard the whistle of a locomotive. There was a train coming from the west, and a few seconds later an electric headlight showed up on the long tangent beyond the siding.

It was a bandit hold-up, all right. We saw the four men at the switch stop the train, which seemed to be a special, since it had only the engine and one passenger car. One of the men stood on the track waving the red lantern; we could see him plainly in the glare of the headlight. There wasn't much of a scrap. There were two or three pistol shots, and then, as near as we could make out, the hold-up men, or some of them, climbed into the engine.

What they did next was as blind as a Chinese puzzle. Before you could count ten they had made a flying switch with the single car, kicking it in on the siding. Before the car had come fully to a stop, the engine was switched in behind it, coupled on, and the reversed train, with the engine pushing the car, rattled away on the old spur that led off into the hills; clattered away and was lost to sight and hearing in less than a minute.

It was not until after the train was switched and gone that we discovered that two of the bandits had been left behind. These two reset the switches for the main track, leaving everything as they had found it, and then crossed over to the auto. Pretty soon we saw match flares, and two little red dots that appeared told us that they were smoking.

"What are they doing, Jimmie?" asked the boss, under his breath.

"They are waiting for the other two to come back," I ventured, taking a chance shot at it. Then I asked him if he knew where the old spur track led to. He said he didn't; that there used to be some bauxite mines back in the hills, somewhere in this vicinity, but he understood they had been worked out and abandoned.

I was just thinking that all this mystery and kidnapping and gun play must be sort of hard on the young woman and the girl, but though my half of the allotment was shivering a little and snuggling up just a grain closer to me, she proved that she hadn't lost her nerve.

"Did you see the name on that car when the engine went past to get in behind it?" she asked, turning the whispered question loose for anybody to answer.

"No," said the boss; and I hadn't, either.

"I did," she asserted, showing that her eyes, or her wits, were quicker than ours. "I had just one little glimpse of it. The name is 'A-l-e-x-a,'" spelling it out.

Mr. Norcross started as if he had been shot.

"The Alexa? That is Mr. Chadwick's private car—they've kidnapped him!" Then he whirled short on me. "Jimmie, are you man enough to go with me and try a tackle on those fellows over there in that auto?"

I said I was; but I didn't add what I thought—that it would probably be a case of double suicide for us two to go up against a pair of armed thugs with our bare hands. The boss would have done it in the hollow half of a minute; he's built just that way. But now the young woman put in her word.

"You mustn't think of doing such a thing!" she protested; and she was still telling him all the different reasons why he mustn't, when we heard the creak and grind of the stolen engine coming back down the old spur.

After that there was nothing to do but to wait and see what was going to happen next. What did happen was as blind as all the rest. The engine was stopped somewhere in the gulch back of us and out of sight from our hiding-place, and pretty soon the two men who had gone with her came hurrying across out of the hill shadows, making straight for the auto. A minute or two later they had climbed into the machine, the motor had sputtered, and the car was gone.

Mr. Chadwick's Special

Of course, as soon as the skip-out of the four hold-up men gave us a free hand we knew it was up to us to get busy and do something. It was a safe bet that the Alexa was carrying her owner, and in that case Mr. John Chadwick and his train crew were somewhere back in the hills, without an engine, and with a good prospect of staying "put" until somebody should go and hunt them up.

Mr. Norcross had our part in the play figured out before the retreating auto had covered its first mile.

"We've got to find out what they've done with Mr. Chadwick," he broke out. And then: "It can't be very far to where they have left the engine, and if they haven't crippled it—" He stopped short and slung a question at the two women: "Will you two stay here with Jimmie while I go and see what I can find in that gulch?"

They both paid me the compliment of saying that they'd stay with me, but the young woman suggested that it might be just as well if we should all go up the gulch together. So we piked out in the dark, the boss helping Mrs. Sheila to hobo along over the cross-ties of the spur, and the little girl stumbling on behind with me. She had got over her scare, if she had any, and when I asked her if she didn't want an arm to grab at, she laughed and said, No, and that it was grand; that she wouldn't miss a single stumble for worlds.

"In all my life I've never had anything half as exciting as this happen to me," was the way she put it, and she sure acted as if she meant to make the most of it.

We had followed the spur track up the gulch for maybe a short quarter of a mile when we came to the engine. There was nobody on it, and the brigands had been good-natured enough to leave the fire-door open so that the steam would run down gently and let the boiler cool off by degrees. Luckily for us, the boss was an expert on engines, just as he is on everything else belonging to a railroad, and he struck matches and looked our find over carefully before he tried to move it. As we had feared it might be, the big machine was crippled. There was a key gone out of one of the connecting-rod crank-pin straps; one miserable little piece of steel, maybe eight inches long and tapering one way, and half an inch or so thick the other; but that was a-plenty. We couldn't make a move without it.

I thought we were done for, but Mr. Norcross chased me up into the cab for a lantern. With the light we began to hunt around in the short grass, all four of us down on our hands and knees doing the needle-in-the-haystack stunt. I had been sensible enough to show the little girl the other connecting-rod key, so she knew exactly what to look for, and it did me a heap of good when it turned out that she was the one who found the lost bit of steel.

"I've got it—I've got it!" she cried; and sure enough she had. The hold-up people had merely taken it out and thrown it aside on the extremely probable chance that nobody would be foolish enough to look for it so near at hand, or, looking, would be able to find it in the dark.

It didn't take more than a minute or two, with a wrench from the engineer's box, to put the key back in place. Then, with one to boost and the other to pull, we got our two passengers up into the high cab, and Mr. Norcross made them as comfortable as he could on the fireman's box, showing them how to brace and hang on when the machine should begin to bounce over the rough track of the old spur.

While he was doing this, I threw a few shovelfuls of coal into the firebox and put the blower on; and when we were all set, the boss opened the throttle and we went carefully nosing ahead over the old track, feeling our way up the gulch and keeping a sharp lookout for the Alexa as we ground and squealed around the curves.

It must have been four or five miles back in the hills to the place where we found the private car, and a little way short of it we picked up Mr. Chadwick's conductor, walking the ties to try to get in touch with the civilized
