The Cattle-Baron's Daughter by Harold Bindloss

A warm wind from the Pacific, which had swept down through the Rockies' passes, had mitigated the Arctic cold, and the snow lay no more than thinly sprinkled upon the prairie. Hetty Torrance and Miss Schuyler were riding up through the birch bluff from the bridge of the Cedar. It was dim among the trees, for dusk was closing in, the trail was rough and steep, and Hetty drew bridle at a turn of it.

"I quite fancied we would have been home before it was dark, and my father would be just savage if he knew we were out alone," she said. "Of course, he wouldn't have let us go if he had been at Cedar."
