"My!" and Susie gave an explosive sigh, "but it's an awful relief not to have that secret to pack around any longer, and to feel that I've got somebody to back me up." A lump rose in Ralston's throat, and, taking her brown little paws in both of his, he said: "To the limit, Susie--to the end of the road." "And my pardner's in on it, too, if he wants to be," she declared loyally, slipping her arm through McArthur's. "To be sure," Ralston seconded cordially. "It will be an adventure for your diary." He added, laying his hand upon McArthur's shoulder: "I'm more than sorry about the mistake this morning, old man. Will you forgive Bear Chief and me?" In all McArthur's studious, lonely life, no person ever had put his hand upon his shoulder and called him "old man." The quick tears filled his eyes, and a glow, tingling in its warmth, rushed over him. The simple, manly act made him Ralston's slave for life, but he answered in his quiet voice: "The mistake was natural, my dear sir." "Smith will be gettin' restless," Susie suggested, "for his breakfast must have been pretty slim. We'd better be startin'. "Now, I'll take straight across the hills in a bee-line, and the rest of you keep me in sight, but follow the draws. When I drop into the canyon, you cache yourselves until I come up and swing my hat. I'll do my best to separate Smith from his gun, but if I can't, I'll throw you the sign to jump him." "I shall arm myself with a pistol, and, if the occasion demands, I shall not hesitate to use it," said McArthur, closing his lips with great firmness. Bear Chief was given a rifle, and then there was a scurrying about for cartridges. When they were saddled, each rode in a different direction, to meet again when out of sight of the ranch. With varied emotions, they soon were following Susie's lead, and it was no easy task to keep the flying figure in sight. McArthur, panting, perspiring, choking his saddle-horn to death, wondered if any person of his acquaintance ever had participated in such a reckless ride. The instructor in Dead Languages, it is true, frequently had thrilled his colleagues with his recital of a night spent in a sapling, owing to the proximity of a she-bear, and McArthur always had mildly envied him the adventure, but now, he felt, if he lived to tell the tale, he had no further cause for envy. Bear Chief's eyes were gleaming with the fires of other days, while the faded overalls and flannel shirt of civilization seemed to take on a look of savagery. Only Ralston's eyes were sombre. He had no thought of weakening, but he had no feeling of elation; though, for the sake of his own self-respect, he was glad to know that his suspicions of Smith were not inspired by jealousy or malice. Now that the opportunity for which he had hoped and waited had come, his strongest feeling was one of sorrow for Dora. With the tenderness of real love, he shrank from hurting her, from mortifying her by the exposé of Smith.
