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.
III
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 world once more. He looked a trifle suspicious when he found the engine in the hands of still another bunch of strangers, and two of them women; but as soon as he heard Mr. Norcross's name he quit being offish and got suddenly respectful. Young as he was for a top-rounder, the boss had a "rep," and I guess there were not very many railroad men west of the Rockies who didn't know him, or know of him.
The conductor told us where we'd find the car, and we found it just as he said we would: pushed in on an old mine-loading track at the end of the spur. The other members of the crew were off and waiting for us; and standing out on the back platform, in the full glare of the headlight as we nosed up for a coupling, there was a big, gray-haired man, bareheaded and dressed in rough-looking old clothes like a mining prospector.
The big man was "Uncle John" Chadwick, and if he was properly astonished at seeing us turn up with his lost engine, he didn't let it interfere with our welcome when we took our passengers around to the car and lifted them one at a time over the railing and climbed up after them. Mr. Chadwick seemed to know Mrs. Sheila; at any rate, he shook hands with her and called her by name. Then he grabbed for the boss and fairly shouted at him: "Well, well, Graham! – of all the lucky things this side of Mesopotamia! How the dev – how in thunder did you manage to turn up here?" And all that, you know.
The explanations, such as they were, came later, after the young lady, confessing herself a bit excited and fussed up, had taken her cousin under her arm and they had both gone to lie down in one of the staterooms. With the women out of the way, the boss and Mr. Chadwick sat together in the open compartment while the train crew was trundling us back to the main line. Mr. Norcross had put me in right by telling the wheat king who I was, so they didn't pay any attention to me.
As a matter of course, the talk jumped first to the mysterious hold-up and kidnapping and the reason why. All either of them could say didn't serve to throw any light on the mystery, not a single ray. There had been no violence – the pistol shots had been merely meant to scare the trainmen – and there had been no attempt at robbery; for that matter, Mr. Chadwick hadn't even seen the kidnappers, and hadn't known what was going on until after it was all over.
Mr. Norcross told what we had seen, and how we had come to be where we were able to see it, but that didn't help out much, either. From any point of view it seemed perfectly foolish, and the boss made mention of that. If we hadn't happened to be there to bring the engine back, the worst that could have befallen Mr. Chadwick and the crew of the special would have been a few hours' bother and delay. In the course of time the conductor would have walked out and got to a wire station somewhere, though it might have taken him all night, and then some, to get another engine.
Naturally, Mr. Chadwick was red-hot about it, on general principles. I guess he wasn't used to being kidnapped. But, after all, the thing that bothered him most was the fact that he couldn't account for it.
"I can't help thinking that it is connected with what is due to happen to-morrow morning, Graham," he said, at the end of things. "There are some certain scoundrels in Portal City at the present moment who wouldn't stop at anything to gain their ends, and I am wondering now if Dawes wasn't mixed up in it."
The boss laughed and said:
"You'll have to begin at the beginning with me: I'm too new in this region to know even the names. Who is Dawes?"
"Dawes is a mining man in Portal City, and before I'd been an hour in town yesterday he hunted me up and wanted me to go over to Strathcona to look at some gold prospects he's trying to finance. I said 'No' at first, because I was expecting you, and thought you'd reach Portal City this morning. When you didn't show up, I knew I had twelve hours more on my hands, and as Dawes was still hanging on, I had our trainmaster give me a special over to Strathcona, on a promise that I'd be brought back early this evening, ahead of the 'Flyer' from the west – the train you were on."
Mr. Norcross nodded. "And the promise wasn't kept."
"No
