I am not exactly a punctilious person, especially on a hot day in the tropics, but as the Fourth did not sit down on any of the numerous vacant chairs in my neighborhood I, somewhat to my surprise, found myself standing up--standing up, as I rarely was inspired to do in the presence of the captain; and the Fourth was almost, if not quite, young enough to be my son. He took my involuntary display of respect for himself and his white uniform as a matter of course, and as the launches were not to return for an hour we leaned against the rail on the shady side and talked, sometimes in English (his English was correct, although limited) but more often in German. That was the beginning of my acquaintance with the Fourth, one that continued under similar circumstances for several months and proved in many respects to be enlightening. More than anything else, perhaps, it brought home to me the meaning of discipline long continued. He had learned his profession on a German training ship, starting in at the age of fourteen, and from there he had gone to the navy. Now he was an officer on one of the great German passenger ships. In the meanwhile he had found time to take and pass the naval examinations that made him eligible to the command of a German vessel in any part of the world, and his age was just twenty-four. I confess I gasped when I heard it (it was the second officer who told me), although I ought to have known it without being told, for from the first I had been struck by his impeccable physical refinement, the kind that but rarely survives a quarter of a century. After that, when he was quietly giving orders to middle-aged quartermasters, skilfully directing the movements of the launches, making mathematical calculations on a slip of paper behind the compass at sunset or pacing the bridge, I often found myself contrasting him with various other young gentlemen of twenty-four some five or six thousand miles away. Living night and day with his watch practically in his hand, rarely sleeping more than four hours at a time, obeying orders and observing regulations blindly, faithfully, without a question or even a thought, had done something to him that was to me very curious, very interesting and very fine. It had not crushed him, it had molded him. It had not changed his nature, it had taken charge of it and directed it. It had not in the least made him prematurely old, it had developed to the fullest extent the capacities of his youth.
