If they could know the ultimate effect of some of their deeds, these would not always seem insignificant. The man who is always on the lookout for little chances for service is more apt to perform services that are of great importance, than the man who spends his time dreaming of big things he will do some day. IV DID HE GO TOO FAR? When an urgent call went out from Washington for physicians to go to France for hospital work among the men of the American Expeditionary Force, a specialist in a city of the Middle West decided to respond. Of course some of his friends told him he was foolish; they urged that he was needed for service at home. "Let doctors go who can be spared better than you," they said. "Think of the great work you are doing--work that will be more than ever necessary because thousands of others are leaving practices and going to the Front. Think of your past--how you worked your way through medical college at cost of severe toil; think of your family and the increasing demands on you; think of the future--what will become of your lucrative practice?" The specialist did think of these things; he had delayed decision because the arguments had presented themselves forcibly to his own mind. At last, however, his mind was made up. He would go to France. He would leave his patients in charge of two capable friends who would do everything possible to turn over, on the return of the volunteer, the lucrative office practice built up through many years. He spent six months in camp with the members of the hospital unit of which he was given charge. Just before he went "over there" a friend said to him: "It is fortunate that your practice is to be cared for so efficiently." "What's that?" was the reply. "Oh, you mean the colleagues who took over my patients? They, too, have enlisted, and will soon be going abroad." "But what of your $35,000 income?" was the dismayed rejoinder. "Surely you haven't the courage to give up all that!" The major snapped his fingers, and said, with a smile, "_That_ for the practice! It is my business to respond to my country's call. Don't talk of the sacrifice. What if I do have to start all over again when I come home? Just now I don't have to think about that."
