By and by they did make steam and begin to move on a course our skipper wigwagged to them. The skipper left the surgeon aboard, and at twenty knots the 352 steamed more circles around the steamer, all lookouts meanwhile skinning their eyes afresh for signs of the sub. We could make out a lot of smoke on the southern horizon. It was the convoy we had left in the morning. An hour later the _Luckenbach_ found her legs. Our cripple broke no records for speed, but she was making revolutions, and by five o'clock we rejoined the convoy with her alongside. So here is an eight hours' log for the 352: At nine in the morning she was responding to S O S-ing ninety miles away; at five in the afternoon we had her tucked away for the night in the column. The tall quartermaster came up on the bridge to stand his watch. We were in our regular position, at the head of the column at twenty knots. He looked back at the fleet. "There you are, Lucky Bag. They must have had you checked up and counted in, a big ship and a three-million-dollar cargo, this morning, and here you are to-night--one they didn't get." THE DOCTOR TAKES CHARGE Every American destroyer over here rates a young surgeon. What some of these surgeons don't know about seagoing can be found in about six hundred pages of Knight's "Modern Seamanship," but that does not matter much. Let them look after the casualties; there are capable young naval officers to look after the seagoing end. Most of these young surgeons have a taste for adventure. If they had not, they would not be over here. The 352 drew one, born and raised in a Southern State. Before coming over here he had viewed the Atlantic once or twice from a distance, which did not quite content him. His ancestors must have crossed that same Atlantic to get to America, and somewhere within him was a high-pitched string that vibrated to every thrill of that same ocean now. He used to speak of these things in the smoking-room of the King's Hotel here, which is where every destroyer officer comes at least once between cruises to get a--cup of coffee. He would have liked to make a few sea voyages when he was a little younger, but if a fellow is ever going to amount to anything he has to settle down sometime and become a respectable member of society--so his folks were always saying, and so he took up medicine. He liked his profession. A doctor can do a heap of good in a suffering world--especially if people will only let him. But so many people want a young doctor to be experienced before they ever will call him in! "Get experience," they say; and not a doggone one in a dozen'll ever give a fellow any chance to get the experience. "What the most of 'em want is for some one else to give us the experience." He did as well as the next young doctor, but at times he would grow almost melancholy sitting before the smoking-room fire telling of his waiting for business in his home town.
