Elsa, clear-headed and matter of fact, was very little annoyed by all this gliding venomous summer life. But little Felicia's horror of it was difficult to control. It seemed to Roger that the child's nerves had been uneven ever since the "cologne affair," as Ernest called it. But he could not be sure of this, for Charley insisted that the little girl's fears of all that uncanny fraternity of the sand was exactly what hers had been four years before.
August was slipping by, quietly enough when Gustav, returning one day from Archer's Springs, delivered to Roger a letter from Hampton of the Smithsonian saying that on the thirtieth day of August a representative of the Smithsonian would reach Archer's Springs on his way to Los Angeles; that he had but two days to spare but would be glad to give these days to the Moore experiment.
Roger was in despair. "Two days!" he groaned. "Why, it takes two days to come up and back. Better stay away."
"Don't be an idiot, Rog," exclaimed Ernest. "You get him here, and he'll stay for a day or so. How can he get away? The thing that bothers me is that darned engine of yours."
"It doesn't bother me," replied Roger, with a quick gleam in his gray eyes and a sudden smile. "I've got a week before he gets here and by Jove, the old kettle's got to be ready!" He gave a sudden long sigh and looked off toward the distant line of the river range. "I thought it was queer of the Smithsonian to treat me as it did. Ern, this puts new life in me."
If new life means redoubled effort, Roger had found it indeed. He gave himself as little sleep as possible during the week before the expected visit. All day and a larger part of the night he was at work in the engine house, till his eyes were bigger and his face gaunter than ever. Felicia was his little shadow. Her taste for mechanics made her seem more like a small boy than ever. And although Roger's tense nerves grew tenser and his impatience with the others was shown oftener and oftener, to Felicia he showed only the gentleness for which she loved him.
Charley and Elsa were forming a real friendship. The isolation of the little desert community was almost complete. Since the death of Von Minden no one from the outer rim of the desert or of the world had been near either camp or ranch. Even the Indians who had been camping in the remote canyon where Felicia had visited them had found good hunting in some still more remote section and never had appeared in the camp. This isolation forced the friendship between the two young women to a quick growth. Charley was happier, Dick said, than he had seen her since her college days.
