“I don't mean to do so, sir.” The next morning, when Dick was with one of the outposts, a man of powerful build, wonderfully quick and alert in his movements, appeared. His coming was so quick and silent that he seemed to rise from the earth, and Dick was startled. The man's face was uncommon. His features were of great strength, the eyes being singularly vivid and penetrating. He was in civilian's dress, but he promptly showed a pass from General Pope, and Dick volunteered to take him to headquarters, where he said he wished to go. Dick became conscious as they walked along that the man was examining him minutely with those searching eyes of his which seemed to look one through and through. “You are Lieutenant Richard Mason,” said the stranger presently, “and you have a cousin, Harry Kenton, also a lieutenant, but in the army of Stonewall Jackson.” Dick stared at him in amazement. “Everything you say is true,” he said, “but how did you know it?” “It's my business to know. Knowledge is my sole pursuit in this great war, and a most engrossing and dangerous task I find it. Yet, I would not leave it. My name is Shepard, and I am a spy. You needn't shrink. I'm not ashamed of my occupation. Why should I be? I don't kill. I don't commit any violence. I'm a guide and educator. I and my kind are the eyes of an army. We show the generals where the enemy is, and we tell them his plans. An able and daring spy is worth more than many a general. Besides, he takes the risk of execution, and he can win no glory, for he must always remain obscure, if not wholly unknown. Which, then, makes the greater sacrifice for his country, the spy or the general?” “You give me a new point of view. I had not thought before how spies risked so much for so little reward.” Shepard smiled. He saw that in spite of his logic Dick yet retained that slight feeling of aversion. The boy left him, when they arrived at headquarters, but the news that Shepard brought was soon known to the whole army. Jackson had left his camp. He was gone again, disappeared into the ether. “Retreated” was the word that Pope at once seized upon, and he sent forth happy bulletins. Shepard and other scouts and spies reported a day or two later that Jackson's army was on the Rapidan, one of the numerous Virginia rivers. Then Dick accompanied Colonel Winchester, who was sent by rail to Washington with dispatches.
