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. Mr. Carlton, ordinarily so bound up in business affairs that he never could leave town, now gave not a thought to them. Instead he took up his abode in the dormitory with Bob that he might be close at hand, and here he eagerly checked off the successive hours that brought nearer that man who was racing against Fate across the vast breadth of the country. How would they meet, these two who had been so long divided by a gulf of years and bitterness? Would his former friend feel that the decisions he had made were wise, or would he heap reproaches upon him for putting in jeopardy a life over which he had no jurisdiction? With dread Mr. Carlton strove to put the thought of the coming interview out of his mind. "I have done as well as I knew," he reiterated. "Would that it had been my own boy instead of his!"
