Brouillard nodded and went a little further into details, showing how the inward-arching barrier would be anchored into the two opposing mountain buttresses.

"And the structure itself—how high is it to be?"

"Two hundred feet above the spillway apron foot."

The lard millionaire twisted his short, fat neck and guessed the distance up the precipitous slopes of Chigringo and Jack's Mountain.

"That will be a whale of a chunk of masonry," he said. Then, with business-like directness: "What will you build it of?—concrete?"

"Yes; concrete and steel."

"Then you are going to need Portland cement—a whole world of it. Where will you get it? And how will you get it here?"

Brouillard smiled inwardly at the pork packer's suddenly awakened interest in the technical ways and means. His four years in the desert had taken him out of touch with a money-making world, and this momentary contact with one of its successful devotees was illuminating. He had a growing conviction that the sordid atmosphere which appeared to be as the breath of life to Mr. J. Wesley Cortwright would presently begin to make things taste coppery, but the inextinguishable charm of the veiled princess was a compensation. It was partly for the sake of seeing her with the veil abolished that he recovered the paper-weighting field-glass and gave it to her, showing her how to focus it upon the upper reaches of the valley.

"We are in luck on the cement proposition," he told the eager money-maker. "We shall probably manufacture our own supply right here on the ground. There is plenty of limestone and an excellent shale in those hills just beyond our camp; and for burning fuel there is a fairly good vein of bituminous coal underlying that farther range at the head of the valley."

"H'm," said the millionaire; "a cement plant, eh? There's money in that anywhere on the face of the globe, just now. And over here, where there is no transportation—Gad! if you only had somebody to sell cement to, you could ask your own price. The materials have all been tested, I suppose?"
