It was on the morning following the startling episode at the Dawsons'

gate that Benson, lately arrived from the west on train 204, came into the superintendent's office with the light of discovery in his eye. But the discovery, if any there were, was made to wait upon a word of friendly solicitude.

"What's this they were telling me down at the lunch-counter just now--about somebody taking a pot-shot at you last night?" he asked.

"Dougherty said it was Bart Rufford; was it?"

Lidgerwood confirmed the gossip with a nod. "Yes, it was Rufford, so Dawson says. I didn't recognize him, though; it was too dark."

"Well, I'm mighty glad to see that he didn't get you. What was the row?"

"I don't know, definitely; I suppose it was because I told McCloskey to discharge his brother a while back. The brother has been hanging about town and making threats ever since he was dropped from the pay-rolls, but no one has paid any attention to him."

"A pretty close call, wasn't it?--or was Dougherty only putting on a few frills to go with my cup of coffee?"

"It was close enough," admitted Lidgerwood half absently. He was thinking not so much of the narrow escape as of the fresh and humiliating evidence it had afforded of his own wretched unreadiness.

"All right; you'll come around to my way of thinking after a while. I tell you, Lidgerwood, you've got to heel yourself when you live in a gun country. I said I wouldn't do it, but I have done it, and I'll tell you right now, when anybody in this blasted desert makes monkey-motions at me, I'm going to blow the top of his head off, quick."

Lidgerwood's gaze was resting on the little drawer in his desk which now contained nothing but a handful of loose cartridges.

"Hasn't it ever occurred to you, Jack, that I am the one man in the desert who cannot afford to go armed? I am supposed to stand for law and order. What would my example be worth if it should be noised around that I, too, had become a 'gun-toter'?"

"Oh, I'm not going to argue with you," laughed Benson. "You'll go your own way and do as you please, and probably get yourself comfortably shot up before you get through. But I didn't come up here to wrangle with you about your theoretical notions of law and order. I came to tell you that I have been hunting for those bridge-timbers of mine."

"Well?" queried Lidgerwood; "have you found them?"

"No, and I don't believe anybody will ever find them. It's going to be another case of Rachel weeping for her children and refusing to be comforted because they are not."

"But you have discovered something?"

"Partly yes, and partly no. I think I told you at the time that they vanished between two days like a puff of smoke, leaving no trace behind them. How it was done I couldn't imagine. There is a wagon-road paralleling the river over there at the Siding, as you know, and the first thing I did the next morning was to look for wagon-tracks. No set of wheels carrying anything as heavy as those twelve-by-twelve twenty-fours had gone over the road."

"How were they taken, then? They couldn't have been floated off down the river, could they?"

"It was possible, but not at all probable," said the engineer. "My theory was that they were taken away on somebody's railroad car. There were only two sources of information, at first--the night operator at Little b.u.t.te twelve miles west, and the track-walker at Point-of-Rocks, whose boat goes down to within two or three miles of the Gloria bridge.

Goodloe, at Little b.u.t.te, reports that there was nothing moving on the main line after the pa.s.sing of the midnight freight east; and Shaughnessy, the track-walker, is just a plain, unvarnished liar: he knows a lot more than he will tell."

"Still, you are looking a good bit more cheerful than you were last week," was Lidgerwood's suggestion.

"Yes; after I got the work started again with a new set of timbers, I spent three or four days on the ground digging for information like a dog after a woodchuck. There are some prospectors panning on the bar three miles up the Gloria, but they knew nothing--or if they knew they wouldn't tell. That was the case with every man I talked to on our side of the river. But over across the Timanyoni, nearly opposite the mouth of the Gloria, there is a little creek coming in from the north, and on this creek I found a lone prospector--a queer old chap who hails from my neck of woods up in Michigan."

"Go on," said Lidgerwood, when the engineer stopped to light his pipe.

"The old man told me a fairy tale, all right," Benson went on. "He was as full of fancies as a fig is of seeds. I have been trying to believe that what he told me isn't altogether a pipe-dream, but it sounds mightily like one. He says that about two o'clock in the morning of Sat.u.r.day, two weeks ago, an engine and a single car backed down from the west to the Gloria bridge, and a crowd of men swarmed off the train, loaded those bridge-timbers, and ran away with them, going back up the line to the west. He tells it all very circ.u.mstantially, though he neglected to explain how he happened to be awake and on guard at any such unearthly hour."

"Where was he when he saw all this?"

"On his own side of the river, of course. It was a dark night, and the engine had no headlight. But the loading gang had plenty of lanterns, and he says they made plenty of noise."

"You didn't let it rest at that?" said the superintendent.

"Oh, no, indeed! I put in the entire afternoon that day on a hand-car with four of my men to pump it for me, and if there is a foot of the main line, side-tracks, or spurs, west of the Gloria bridge, that I haven't gone over, I don't know where it is. The next night I crossed the Timanyoni and tackled the old prospector again. I wanted to check him up--see if he had forgotten any of the little frills and details. He hadn't. On the contrary, he was able to add what seems to me a very important detail. About an hour after the disappearance of the one-car train with my bridge-timbers, he heard something that he had heard many times before. He says it was the high-pitched song of a circular saw. I asked him if he was sure. He grinned and said he hadn't been brought up in the Michigan woods without being able to recognize that song wherever he might hear it."

"Whereupon you went hunting for saw-mills?" asked Lidgerwood.

"That is just what I did, and if there is one within hearing distance of that old man's cabin on Quartz Creek, I couldn't find it. But I am confident that there is one, and that the thieves, whoever they were, lost no time in sawing my bridge-timbers up into board-lumber, and I'll bet a hen worth fifty dollars against a no-account yellow dog that I have seen those boards a dozen times within the last twenty-four hours, without knowing it."

"Didn't see anything of our switch-engine while you were looking for your bridge-timbers and saw-mills and other things, did you?" queried Lidgerwood.

"No," was the quick reply, "no, but I have a think coming on that, too.

My old prospector says he couldn't make out very well in the dark, but it seemed to him as if the engine which hauled away our bridge-timbers didn't have any tender. How does that strike you?"

Lidgerwood grew thoughtful. The missing engine was of the "saddle-tank"

type, and it had no tender. It was hard to believe that it could be hidden anywhere on so small a part of the Red b.u.t.te Western system as that covered by the comparatively short mileage in Timanyoni Park. Yet if it had not been dumped into some deep pot-hole in the river, it was unquestionably hidden somewhere.

"Benson, are you sure you went over all the line lying west of the Gloria bridge?" he asked pointedly.

"Every foot of it, up one side and down the other ... No, hold on, there is that old spur running up on the eastern side of Little b.u.t.te; it's the one that used to serve Flemister's mine when the workings were on the eastern slope of the b.u.t.te. I didn't go over that spur. It hasn't been used for years; as I remember it, the switch connections with the main line have been taken out."

"You're wrong about that," said Lidgerwood definitely. "McCloskey thought so too, and told me that the frogs and point-rails had been taken out at Silver Switch--at both of the main-line ends of the 'Y',--but the last time I was over the line I noticed that the old switch stands were there, and that the split rails were still in place."

Benson had been tilting comfortably in his chair, smoking his pipe, but at this he got up quickly and looked at his watch.

"Say, Lidgerwood, I'm going back to the Park on Extra 71, which ought to leave in about five minutes," he said hurriedly. "Tell me half a dozen things in just about as many seconds. Has Flemister used that spur since you took charge of the road?"

"No."

"Have you ever suspected him of being mixed up in the looting?"

"I haven't known enough about him to form an opinion."

Benson stepped to the door communicating with the outer office, and closed it quietly.

"Your man Hallock out there; how is he mixed up with Flemister?"

"I don't know. Why?"

"Because, the day before yesterday, when I was on the Little b.u.t.te station platform, talking with Goodloe, I saw Flemister and Hallock walking down the new spur together. When they saw me, they turned around and began to walk back toward the mine."

"Hallock had business with Flemister, I know that much, and he took half a day off Thursday to go and see him," said the superintendent.

"Do you happen to know what the business was?"

"Yes, I do. He went at my request."

"H'm," said Benson, "another string broken. Never mind; I've got to catch that train."

"Still after those bridge-timbers?"

"Still after the boards they have probably been sawed into. And before I get back I am going to know what's at the upper end of that old Silver Switch 'Y' spur."
