A remarkable instance of bravery and self-sacrifice is shown in the story of Kate, sister of a Western settler's wife. Kate's lover is Captain Haynes, stationed at a nearby Army post. She sees and misunderstands a kiss between Haynes and Milly Lee; heartbroken, she joins her sister and brother-in-law on a long journey across the plains. Marauding Indians attack and capture Kate. The others carry the news to the Army post and Haynes heads a rescue party. He becomes separated from his men and is also captured. Kate saves him from the stake by threatening to drop the Indian Chief's child over a precipice, and Haynes brings up his troop. The Indians are driven off, but one hides near the wigwam where Kate is and attempts to stab her. Haynes sees this and just as the rascal is about to strike, he pounces on him and kills him. On their way back to the fort, Haynes explains the kiss incident satisfactorily, and the lovers are joyfully reunited.
