"I'll do anything you wish," returned Dan, accompanying him along the garden path. "What do you want me to do?"

"To ride to Hilton's Jump to-night," said Silk, "and break the news to Marie Jolicœur about what has happened to her son. And perhaps while you are there in the half-breeds' village you might be able to discover who were Henri's enemies. I can trust you to be discreet."

Dan said nothing of this affair to Percy Rapson, leaving Percy to guess what he liked concerning his reason for going out on horseback after Silk had said good-night and ridden off alone along the trail.

On the next morning Sergeant Silk was back again at Rattlesnake Ranch, on the same chestnut mare. He had had no sleep, but if he was fatigued the fact was not betrayed in his appearance, for his eyes were as brightly alert as always. He had shaved. His dark moustache had its usual curl, and his brown canvas uniform—even to the shine on his long boots and the gleam of newly-polished brass in buttons and cartridges—was as tidy as if he were going on parade.

Dan Medlicott met him as he approached the homestead.

"I see you did not fail to go to Hilton's Jump last night," the sergeant smiled.

Dan looked at him queerly.

"How do you know?" he asked.

Silk glanced down at the feet of Dan's pony.

"By the mud on your broncho's fetlocks," he answered. "You took the short cut by the edge of the marsh, and you didn't give yourself time to groom your plug this morning. Well, have you any news? Did you see Marie Jolicœur?"
