"Dr. Carey, when I saw Lieutenant Alford brought in I counted the cost again. Only American ideals of government and civilization can win this wilderness. For this Alford's blood was shed. He wrote to his mother on Christmas day that he was studying here to get his Master's Degree from the Kansas University. I saw him just after he had received his diploma for that Degree. I was a fairly law-abiding civilian. The first shot of the campaign last February began in me what Alford's sacrifice completed. I am waiting to see what next. But I have one thing firmly fixed now. Warfare only opens the way for the wilderness winners to come in and make a kingdom. The Remington rifle runs back the frontier line; the plowshare holds the land at last. I want, when my service here is done, to go back to the wheatfields and the cornfields. I want to smell the alfalfa and see the prairie windbreaks and be king of a Kansas farm. I've lost my ambition for gold lace. I want a bigger mental ring of growth every year, and I believe the biggest place for me to get this will be with my feet on the prairie sod. Meantime, I shall reenlist, as I said." "Sit down, Thaine, and let me ask you one question," Dr. Carey said. The young man dropped to his seat again. "When your service is done is there anything to hold you from going straight to the Grass River Valley again?" Thaine leaned back in his chair and clasped his hands behind his head while he looked steadily at the splashing waters before him as he said frankly: "Yes, there is. When I go back I want Leigh Shirley--and it's no use wanting." "Thaine, you were a law-abiding civilian at home. The university made you a student. You came out here a fearless soldier to fight your country's enemies. Alford's death made you a patriot who would plant American ideals in these islands. May I tell you that there is still one more lesson to learn?" Thaine looked up inquiringly. "You must learn to be a Christian. You must know what service for humanity means. Then the call to duty will be a bugle note of victory wherever that duty may be. You needn't hunt for opportunity to prove this. The opportunity is hurrying toward you now from out of the Unknown." The fine head with the heavy masses of white hair seemed halo-crowned at that moment. It was as he appeared that night that Thaine Aydelot always remembers him. Two weeks later Thaine enlisted in the Fourteenth United States Infantry, stationed in Luzon. Dr. Carey was also enrolled in its hospital staff. In July the regiment was ordered from the Philippines to join the allied armies of the World Powers at Tien-Tsin in a northern Chinese province, where the Boxer forces were massing about Peking. And Thaine's opportunity for learning his greatest lesson came hurrying toward him from out of the Unknown.
