"Perhaps he's making bombs," laughed Harold, and the rest of the family joined in the laugh. That is, all but Bob, who took the suggestion seriously, and his heart thumped a beat faster at the thought. In fact, as he went to bed that night his mind was filled with thoughts of spies, and plotters, and the hundred and one other things connected with the war that he and his family had discussed that evening. He went to the closet and took out the .22 caliber rifle that he owned; it was in good condition and Bob assured himself that he had plenty of cartridges, though he knew so small a gun would be of but little use in time of trouble. As he undressed he thought over the events of the day. Never had he experienced such excitement. War had been declared, and many of the young men, not much older than he, had enlisted. He, too, wanted to go in the worst way, but he knew that his father and brother were right when they said he would not be accepted. "Why not?" muttered Bob to himself. "I'm big enough and strong enough too; I could stand it as well as most of those fellows, even if they are older. Besides I weigh a hundred and fifty-three and I'm five feet nine inches tall. Perhaps they won't take me because I've got light hair and blue eyes," he murmured bitterly. "They think I look like a German." Stripped to the skin he stood in front of the mirror and looked at himself. Certainly he was big and strong. He had always lived a clean, outdoor life, he had been active in athletics and right now was captain of the high school baseball team. The muscles played and rippled under his white skin, as he moved his lithe young body to and fro. A few breathing exercises before he jumped into bed, and then he was under the covers. And all night long he dreamed of chasing big fat Germans up and down the streets, over fences, and across fields, and even up the steep sides of houses. Usually just as he had caught up with them he awoke. Most of all he dreamed he was pursuing Karl Wernberg, who was a middle-aged German and not hard to overtake. But Bob did not catch him because he always woke up too soon. CHAPTER II THE SECRET SERVICE AT WORK The following morning Bob was in the trolley car on his way to school. The car was full, and every one was eagerly scanning a newspaper or discussing the war with his neighbor. Words of praise for the President were to be heard on all sides, and enthusiasm was everywhere in evidence. Old men wished they were young enough to enlist. All at once Bob heard voices raised in dispute. The trouble was at the opposite end of the car, but he could hear plainly what was said. "It is wrong, all wrong," exclaimed a florid-faced man with a light mustache, who plainly was of German blood. "What has Germany done to this country?" "They've sunk our ships when they had no right to, and they've murdered our peaceful citizens," said the man next to him. "Isn't that enough?" "They were forced to do it," the German insisted.
