"Not much!" said the new chief contemptuously. And then he asked which of the two bunks in the adjoining sleeping-room was his.

ELBOW CANYON

Ballard had his first appreciative view of his new field of labor before breakfast on the morning following his arrival, with Bromley as his sightsman.

Viewed in their entirety by daylight, the topographies appealed irresistibly to the technical eye; and Ballard no longer wondered that Braithwaite had overlooked or disregarded all other possible sites for the great dam.

The basin enclosed by the circling foothills and backed by the forested slopes of the main range was a natural reservoir, lacking only a comparatively short wall of masonry to block the crooked gap in the hills through which the river found its way to the lower levels of the grass-lands.

The gap itself was an invitation to the engineer. Its rock-bound slopes promised the best of anchorages for the shore-ends of the masonry; and at its lower extremity a jutting promontory on the right bank of the stream made a sharp angle in the chasm; the elbow which gave the outlet canyon its name.

The point or crook of the elbow, the narrowest pass in the cleft, had been chosen as the site for the dam. Through the promontory a short tunnel was driven at the river-level to provide a diverting spillway for the torrent; and by this simple expedient a dry river-bed in which to build the great wall of concrete and masonry had been secured.

"That was Braithwaite's notion, I suppose?" said Ballard, indicating the tunnel through which the stream, now at summer freshet volume, thundered on its way around the building site to plunge sullenly into its natural bed below the promontory. "Nobody but a Government man would have had the courage to spend so much time and money on a mere preliminary. It's a good notion, though."
