As the through express thundered past station after station, Perry had one swift pang of regret to think of the school commencement and the games he would miss, but when he thought of what was ahead of him, the thrill of doing real things came over him like a tornado and swept aside all thoughts of school. That his learning was not over, but only just beginning, he thoroughly realized, for along this line had been his father’s parting words: “In some fields, son,” he had said to Perry, “you can succeed by making a bluff, but in scientific work you’ve got to know, and to know that you know. Science is real and big, all the way through.” Dr. Hunt met the boy at the New York terminal. Although uncle and nephew knew each other in the vague way that relatives do, neither had ever thought of the other as taking a place in his life, and each anticipated the meeting with great interest. The professor’s first thought was that the boy looked rugged and sturdy, and Perry’s first thought was that there was far more of command in his uncle’s manner than he remembered. Recalling his father’s advice against “bluffing,” Perry was careful in his statements as he chatted with his uncle on the way to the steamer and consequently gave a favorable impression. “Your father tells me you know considerable paleontology,” said the leader of the expedition. “I’ve always been keen on fossils,” the boy replied, “and so I’ve managed to pick up little bits about it. But of course I haven’t really studied; not the way I hope to, some day.” “You know your geological periods, I suppose?” “Backwards!” replied Perry confidently, for he knew that he really did know them, and his friend in the Museum had taught him to see how important was this groundwork in any fossil studies that he might do. So, when his uncle, in a few sharp questions, put him on the rack, Perry came out of the ordeal well, because he had only claimed to know exactly the things he did know. As a result, he won from the accurate and careful scientist the golden opinion: “I shouldn’t be surprised, lad, if we made a paleontologist out of you, after all.”
