"Why, it's simple," she told him. "It's this way: Demarest, Spruce & Tillou have the main contract here—a hundred miles, I've heard. When a big company like that contracts to build a hundred miles of grade, they at once begin to sublet portions to smaller contractors. Some take a mile; some two miles, some five—according to the nature of the work and the respective capacities of their outfits. Understand?"

"Yes—I got that."

"Well, it's natural, then, that the most difficult pieces—the biggest work—will be the most difficult to sublet. Consequently when the main contractors can sublet no more, they move in and get at the difficult pieces that remain on their hands.

"Now, I've seen a good bit of this line, and I've talked with the engineers. Also I know the names of most of the subcontractors who have figured on the job. I know that none of them have adequate equipment to tackle the big rock cut that will be necessary through that chain of buttes, twelve miles to the south of here."

She pointed to the buttes, blue and hazy in the evening light of the desert.

"So, my friend, it follows as the night the day that Demarest, Spruce & Tillou will eventually move in with their heaviest-hitting outfit to run that cut, which certainly will be left on their hands. It follows as the night the day, again, that the leeches who always drift in to get the stiff's pay day away from them will settle near the biggest camp, if there's sufficient water.

"Down near those buttes, where the big camp is bound to be, there's plenty of water, and before many days have passed Ragtown in all its glory will be erected right there.

"These supplies that we're hauling now are charged to the account of Demarest, Spruce & Tillou," she further explained. "You see, they furnish their subs with everything they need. Now when Demarest, Spruce & Tillou move in there will be little or no freighting for us to any camp but theirs. All goods will be concentrated in their commissary then, and the subs will buy direct from them and do their own hauling to the various camps. Of course, Ragtown will have to be supplied—but Ragtown and Demarest, Spruce & Tillou's Camp Number One will be virtually the same as regards our freight terminus."

"And how long before the main contractors will get here?" he asked, working his twisted nose from side to side as if in the hope of eventually persuading it to point dead ahead.

"That all depends on whether they have given up trying to sublet any more work or not. If they think they won't be able to load any one else up with a job, they'll be in directly—almost any day. But if they still think there's a chance to get rid of the hard pieces, they'll hold off until the matter is settled, of course."
