“The Old Wives’ Slough. It is the furthest point that I have been with my father. About ten miles west of here, and the same distance north of the Slavi village.”

“Have you been there?” Conacher asked Mary-Lou.

She shook her head.

“Do you know the North Star?”

She nodded.

“Good! Then take the horses and the grub when it becomes dark to-morrow night, and ride ten miles in the direction of the North Star to that slough in the prairie.”

“There is a trail from the Slavi village,” put in Loseis.

“Loseis and I will be waiting for you there,” said Conacher.

“In the poplar bluff on the south side of the slough,” added Loseis.

“If we are not there,” added Conacher with a smile for Loseis’ benefit, “why, turn around and ride back to the Slavi village.”
