There was a certain condescension in the tone of "King" Plummer, but Harley did not mind it; so far as the experience of life in the rough was concerned, the "King" had a right to condescend. "I shall hold you to your promise," he said. Then "King" Plummer, waving good-byes with a wide-armed sweep, large and hearty like himself, departed. "There goes a true man," said Mr. Grayson, and Harley spontaneously added confirmation. But Miss Morgan was silent. She waved back in response to the King of the Mountains, but her face was still pale, and she was silent for some time. Harley now knew that "King" Plummer was not her uncle nor her next of kin after Jimmy Grayson in any way, but he was unable to tell why this marriage-to-be had been arranged. But he quickly learned the secret, if secret it was; it was told to him on the train by Mrs. Grayson as they rode that afternoon to Detroit. "If you were ever in Idaho," she said, "you would soon hear the story of "King" Plummer and Sylvia. It is a tragedy of our West; that is, it began in a great tragedy, one of those tragedies of the plains and the mountains so numerous and so like each other that the historians forget to tell about them. Sylvia's mother was Mr. Grayson's eldest sister, much older than he. She and her husband and children were part of a wagon-train that was going up away into the Northwest where the railroads did not then reach. "It was long ago--when Sylvia was a little girl, not more than seven or eight--and the train was massacred by Utes just as they reached the Idaho line. The Utes were on the war-path--there had been some sort of an outbreak--and the train had been warned by the soldiers not to go on, but the emigrants were reckless. They laughed at danger, because they did not see it before their faces. They pushed on, and they were ambushed in a deep canyon. "There was hardly any fight at all, the attack was so sudden and unexpected. Before the people knew what was coming half of them were shot down, and then those awful savages were among them with tomahawk and knife. Mr. Harley, I've no use for the Indian. It is easy enough to get sentimental about him when you are away off in the East, but when you are close to him in the West all that feeling goes. I heard Sylvia tell about that massacre once, and only once. It was years ago, but I can't forget it; and if I can't forget it, do you think that she can? Her father was killed at the first fire from the bushes, and then an Indian, covered with paint and bears' claws, tomahawked both her mother and her little brother before her eyes--yes, and scalped them, too. He ran for the girl next, but Sylvia--I think it was just physical impulse--dashed away into the scrub, and the Indian turned aside for a victim nearer at hand.
