"Quiet, Don! Quiet!" the girl called.

She stood waiting. Silk observed that she was dressed in dark serge and wore a green felt sun hat, which did not wholly conceal her very fair hair. He also noticed that she carried an artist's canvas and a portable easel.

"How do, officer?" the girl said in response to his salutation, as he drew to a halt in front of her. "The sight of your uniform is like a rainbow. It signifies hope."

"Hope?" he smiled. "Hope of what?"

"Hope that you are here to protect a lone and defenceless wayfarer from danger," she answered him. "My teamster alarms me with the news that there is a notorious highwayman prowling around in these parts. Naturally the presence of a member of the Mounted Police is reassuring." She glanced at the stripes on his arm. "Won't you dismount, Sergeant?" she asked.

Sergeant Silk slipped from his saddle.

"I'm glad to know that you have been warned," he said. "I can't deny that the warning is reasonable. As a matter of fact, we are at present hunting for that same highwayman."

"I hope you will catch him," the girl urged. "One hardly expects to be troubled by such characters in peaceful, law-abiding Alberta. I hope sincerely that he will be arrested. Do you think he will be, Sergeant? Shall I be safe, camping here?"

"You need not be afraid," Silk assured her. "Whatever else happens, Nick-By-Night shall not be allowed to interrupt your sketching tour."

The girl looked at him in amused wonder.
