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 Butte 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 Butte, reports that there was nothing moving on the main line after the passing 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.
