Dick Forrest had been right when he told his guardians that his mind was acid and would bite into the books. Never was there such an education, and he directed it himself--but not without advice. He had learned the trick of hiring brains from his father and from John Chisum of the Jingle-bob. He had learned to sit silent and to think while cow men talked long about the campfire and the chuck wagon. And, by virtue of name and place, he sought and obtained interviews with professors and college presidents and practical men of affairs; and he listened to their talk through many hours, scarcely speaking, rarely asking a question, merely listening to the best they had to offer, content to receive from several such hours one idea, one fact, that would help him to decide what sort of an education he would go in for and how. Then came the engaging of coaches. Never was there such an engaging and discharging, such a hiring and firing. He was not frugal in the matter. For one that he retained a month, or three months, he discharged a dozen on the first day, or the first week. And invariably he paid such dischargees a full month although their attempts to teach him might not have consumed an hour. He did such things fairly and grandly, because he could afford to be fair and grand. He, who had eaten the leavings from firemen's pails in round-houses and "scoffed" mulligan-stews at water-tanks, had learned thoroughly the worth of money. He bought the best with the sure knowledge that it was the cheapest. A year of high school physics and a year of high school chemistry were necessary to enter the university. When he had crammed his algebra and geometry, he sought out the heads of the physics and chemistry departments in the University of California. Professor Carey laughed at him... at the first. "My dear boy," Professor Carey began. Dick waited patiently till he was through. Then Dick began, and concluded. "I'm not a fool, Professor Carey. High school and academy students are children. They don't know the world. They don't know what they want, or why they want what is ladled out to them. I know the world. I know what I want and why I want it. They do physics for an hour, twice a week, for two terms, which, with two vacations, occupy one year. You are the top teacher on the Pacific Coast in physics. The college year is just ending. In the first week of your vacation, giving every minute of your time to me, I can get the year's physics. What is that week worth to you?" "You couldn't buy it for a thousand dollars," Professor Carey rejoined, thinking he had settled the matter. "I know what your salary is--" Dick began. "What is it?" Professor Carey demanded sharply.
