The two men were an interesting contrast; Dr. Parkman was singularly, conspicuously dark, while Karl Hubers was a true Teuton in colouring. Dr. Parkman was a large man, and all of him seemed to count for force. Something about him made people prefer not to get in his way. It was his hands spoke for his work--superbly the surgeon's hands, that magical union of power and skill, hands for the strongest grip and the lightest touch, lithe, sure, relentless, fairly intuitive. His hands made one believe in him. With Karl it was the eyes told most. They seemed to be looking such a long way ahead, and yet not missing the smallest thing close at hand. As he talked now, his face lighted with enthusiasm, it occurred to Dr. Parkman that Hubers was a curious blending of the two kinds of men there were behind him. Some of those men had been fighters and some had been thinkers, but Karl was the thinker who fights. He had drawn from both of them, and that gave him peculiar fitness for the work he was doing. It was work for the thinker, the scholar, but work which must have the fighting blood. Even his appearance bore the mark of the two kinds of things bequeathed him. He had the well-knit body of the soldier, the face of the student. He was not a large man, but he gave the sense of large things. He had the slight stoop of the laboratory, but when interested, aflame, he straightened up and was then in every line the man who fights. His eyes, to the understanding observer, told the story of much work with the microscope. They were curiously, though not unattractively, unlike. The left he used for observations, the right for making the accompanying drawings. That gave them a peculiarity only the man of science would understand. The things which the two men radiated were different things. One felt their different adjustment toward life. Dr. Parkman had turned to hard work as some men turn to strong drink, to submerge himself, to take him out of himself, to make life possible; while with Karl Hubers, work and life and love were all one great force. Dr. Parkman worked in order that he might not remember; Karl in order that he might fulfill.
