"But now," he went on, his eyes clear, but his brows drawn over them, "we come to something different—entirely different. Out yonder in the lap of the desert is what they call Rattlesnake Valley. It is no valley at all, merely a great depression, a sort of natural sink. It is twenty miles wide, forty miles long. I have found no drop of water within thirty miles of it, no single spring, no creek. It is nothing but sand—dry, barren, unfertile sand—five hundred square miles of it, to look at it. And right there, in the heart of that sink, I am going to build a town."

He spoke quietly, his voice low, no hint of boastfulness in his tone, no hint of doubt. He spoke as a man who has studied his ground and who knows both the difficulties which lie ahead of him and the possibilities. Conniston, seeing only the impossibility, the madness of such a project, looked questioningly from him to the girl. Argyl's face was flushed, her eyes were very bright with an intense eager interest.

"It sounds so big," Conniston hesitated, his gaze coming back to the older man's face. "So daring, so impossible!"

"It is big! Bigger than I have even hinted at. It is daring. Of course, I take a chance of sinking everything I have out there and finding only failure in the end."

He shrugged his shoulders, and Conniston noticed for the first time how big and broad they were.

"But it is not impossible. It is merely the repetition of such work as has been done successfully in the Imperial Valley. The stuff which looks to be sand—barren, unfertile sand—is the richest soil in the world. Put water on it and you can raise anything. Reclamation work is a fairly new thing with us, Conniston. Men have been content heretofore to squat in the green valleys and let the desert places remain the haunts of the horned toad and coyote. But now the green valleys are filling up, and there are hundreds of thousands of square miles like the country you rode over from Indian Creek to the Half Moon which are calling to us. To redeem them from barrenness, to do the sort of work which our friends have done in the Imperial Valley, is pioneer work. The pioneers ever since Adam, be it the Columbuses of early navigation or the Wrights of aerial navigation, have always taken the long chances. They are the ones who have suffered the hardships, and who, often enough, have been forgotten by the world in its mad rush along the trail they have opened. But they are the men who have done the big things. The pioneers are not yet all gone from the West, thank God! And their work is reclamation work!"

"And it's for the work over there that you want an engineer?"

"Yes. I want him bad, too. Do you happen to know one?"

"I know one. I won't say how much good he is, though. I'm an engineer myself."

"You!" It was Argyl's voice, surprised but eager.
