Van was bubbling over with high spirits when he left Tim that afternoon and there was nothing to herald the approach of the calamity that fell like a thunderbolt upon him. It was late at night when the illness developed that so alarmed Bob Carlton that it sent him rushing to the telephone to call up the head master. From that moment on things moved with appalling rapidity. Van was carried from the dormitory to the school hospital and at the doctor's advice Mr. Carlton was summoned from New York by telephone. Within an incredibly few hours both he and his wife arrived by motor, and their first act was to wire Van's father. The boy was very ill, so ill that in an operation lay the one slender chance of saving his life. The case could brook no delay. There was not sufficient time to consult Van's father, or learn from him his preferences as to what should be done. To Mr. Carlton fell the entire responsibility of taking command of the perilous situation. He it was who secured the famous surgeon from New York; who sent for nurses and doctors; who made the decision that meant life or death to the boy who lay suffering on the cot in that silent room. How leaden were the hours while the lad's existence trembled in the balance! Mr. Carlton paced the floor of the tiny office, his hands clinched behind him and his lips tightly set. If Van did not survive his would be the word that had sent him to his end. Should the worst befall how should he ever greet that desperate father who was even now hurrying eastward with all the speed that money could purchase? What should he say? What could he say, Mr. Carlton asked himself. To lose his own child would be a grief overwhelming enough; but to have given the order that hurried another man's only boy into eternity--that would be a tragedy that nothing could ever make right. "I have done the best I knew," muttered Mr. Carlton over and over to himself. "I have done toward his son precisely as I would have done toward my own. Had I it all to decide over again I could do nothing different." Yet try as he would to comfort himself the hours before he could have tidings from the operating room dragged with torturing slowness. Bob, crouched in a chair in the corner of the room, dared not speak to his father. Never had he seen him so unnerved. There was no need to question the seriousness of the moment; it brooded in the tenseness of the atmosphere, in the speed with which his heart beat, in the drawn face of the man who never ceased his measured tread up and down the narrow room. And when the strain of the operation was actually over there was no lessening of anxiety, because for days following the battle for life had still to be waged. Would human strength hold through the combat? That was the question that filled the weary hours of the day and the sleepless watches of the night.
