Two days before the visitor was due, Roger announced that one day's work would make him ready for a test, so that, and he did not believe that he was over-confident, when Gustav arrived with the Smithsonian investigator, the plant would be in full action. He made this announcement at breakfast. Ernest and Gustav cheered.
"I never thought you'd make it," said Gustav.
"I had to make it," replied Roger. "I have the conviction that if this man, whoever he is, sees the plant working, the thing will be done, and that if he doesn't find the wheels going round, I'm going to miss the chance of my life."
"If the heat would just let up for a little while," sighed Ernest. "If he's a northerner, it may put him out of business."
"Pshaw! they'll send an experienced man, never fear!" Roger poured himself another cup of coffee. "Hello! Here's a caller!"
It was Qui-tha, riding a half-starved pony whose mangy sides were working in the early morning sun like a pair of bellows.
He dismounted and grinned affably. "How! You give Qui-tha more strong medicine, maybe!"
"Look here, Qui-tha, I'll give you all the strong medicine you want, if you'll stay and help me for a week," cried Ernest.
Qui-tha shook his head. "No got time to work. Must go back to Injun camp take care of sick Injun. Qui-tha heap big medicine man, now."
"All right!" Ernest shrugged his shoulders. "No work, no strong medicine."
Qui-tha shrugged his shoulders and remounting, he started on up the trail to the ranch house. Elsa reported later in the day that Dick, having no peroxide, had promised to get some from Archer's Springs if Qui-tha would do a day's work for him. Qui-tha, she said, was giving the matter due consideration.
Late that evening, while Roger and Gustav were working at the little forge, Ernest came out of the living tent where he had been writing letters.
"Did you fellows hear a gun shot a little bit ago?" he asked. "You two are making such an infernal racket, I can't tell what it was."
Roger and Gustav both stopped work and listened. The desert was breathlessly silent.
"Are you sure?" asked Roger. "Did you think it might have been at the ranch?"
"I couldn't tell. It may have been nothing at all but you folks here. But if I hear it again, I'm going up there."
It was fifteen or twenty minutes later that Elsa's voice came from the trail.
"Ernest! Roger! Gustav!"
The three men started on a run to meet her. A dark figure in the starlight, she staggered exhausted toward them.
