“That’s so!” agreed Mack. “It couldn’t be Bob, for he’d know these mules, and he ain’t been to the Bar-T for quite a spell. I dunno who that kin be, then, Miss Frances.”

Frances had had her light fowling-piece put in the wagon, and before noon she sighted a flock of the scarce prairie chickens. Away she scampered on Molly after the wary birds, and succeeded, in half an hour, in getting a brace of them.

Mack picked and cleaned the chickens on the wagon-seat. “They’ll help out with supper to-night, if Miz’ Peckham ain’t expectin’ company,” he remarked.

But they were not destined to arrive at the Peckham ranch without an incident of more importance than these.

It was past mid-afternoon. They had had their cold bite, rested the mules and Molly, and the latter was plodding along in the shade of the wagon-top all but asleep, and her rider was in a like somnolent condition. Mack was frankly snoring on the wagon-seat, for the mules had naught to do but keep to the trail.

Suddenly Molly lifted her head and pricked her ears. Frances came to herself with a slight shock, too. She listened. The pinto nickered faintly.

Frances immediately distinguished the patter of hoofs. A single pony was coming.

The girl jerked Molly’s head around and they dropped back behind the wagon which kept on lumberingly, with Mack still asleep on the seat. From the south–from the direction of the distant river–a rider came galloping up the trail.

“Why!” murmured Frances. “It’s Ratty M’Gill!”

The ex-cowboy of the Bar-T swung around upon the trail, as though headed east, and grinned at the ranchman’s daughter. His face was very red and his eyes were blurred, and Frances feared he had been drinking.
