"Good-morning!" he said. "What's the matter?"
Rhoda started, hastily covered her foot, and looked up at the tall khaki-clad figure. She never had seen the young man before, but the desert is not formal.
"A thing like a little crayfish bit my foot," she answered; "and you don't know how it hurts!"
"Ah, but I do!" exclaimed the young man. "A scorpion sting! Let me see it!"
Rhoda flushed.
"Oh, never mind that!" she said. "But if you will go to the Newman ranch-house for me and ask them to send the buckboard I'll be very grateful. I--I feel dizzy, you know."
"Gee whiz!" exclaimed the young man. "There's no time for me to run about the desert if you have a scorpion sting in your foot!"
"Is a scorpion sting dangerous?" asked Rhoda. Then she added, languidly, "Not that I mind if it is!"
The young man gave her a curious glance. Then he pulled a small case from his pocket, knelt in the sand and lifted Rhoda's foot in one slender, strong, brown hand. The instep already was badly swollen.
"Hold tight a minute!" said the young man.
And before Rhoda could protest he had punctured the red center of the swelling with a little scalpel, had held the cut open and had filled it with a white powder that bit. Then he pulled a clean handkerchief from his pocket and tore it in two. With one half he bound the ankle above the cut tightly. With the other he bandaged the cut itself.
