"You're not going yet, Charley," exclaimed Roger, in alarm. "You must stay to supper."

"I never was so popular in my life," laughed Charley. "Of course I'll stay. Let me have a look at the new well, Roger. Do you think it's going to meet your demands?"

She crossed the camp to admire the new pump, Roger following.

"I don't think it will do more than supply engine and camp needs," replied Roger. "I don't know whether to go ahead, prospecting for water, or to erect the plant first."

"Why don't you erect your plant, then if you don't find enough water after drilling for it, with your engine, move up to the ranch and use our spring. I'm not trying to graft something free. We'll be glad to pay for it. But our old gasoline engine is an awful lemon and it's going to be an awful job to keep up the supply of gasoline."

"Jove! My first customer? Charley, you're a peach!" exclaimed Roger. "I suppose I might put my plant up on your place to begin with. But no, this is the spot the Smithsonian picked, it's government land, and to move now might make endless complications. But you'll have your pumping plant, Charley, before any one else does. And we'll make the alfalfa crops pay for it."

Charley nodded, then gasped, "Look, Roger! Oh, if Ernest and Dick could only steal in now!"

The guest had pulled her rocker out before the tent flap and was seated in it, eyes closed, hands clasped over her stomach, immovable except for a light swaying of her chair.

"Concentrating, I suppose," muttered Roger. "Charley, I'll bet the old bird will never leave me. I have the feeling."

"What on earth does she mean by concentrating?" gasped Charley, through her laughter.
