“Ornithology? That's a big word, but I suppose it will serve. We'll drop the matter, and if at any time my words here should be quoted I'll promptly deny them. It's a bad thing for a boy to have his statements disputed by a man of years who can command wealth and other powerful influences. Unless he had witnesses nobody would believe the boy. I tell you this, my lad, partly for your own good, because I'm inclined to like you.” Dick stared. There was nothing insulting in the man's tone. He seemed to be thoroughly in earnest. Perhaps he regarded his point of view as right, and Dick, a boy of thought and resource, saw that it was not worth while to make a quarrel. But he resolved to remember Watson, feeling that the course of events might bring them together again. “I suppose it's as you say,” he said. “You're a man of affairs and you ought to know.” Watson smiled at him. Dick felt that the contractor had been telling the truth when he said that he was inclined to like him. Perhaps he was honest and supplied good materials, when others supplied bad. “You will shake hands with me, Mr. Mason,” he said. “You think that I will be hostile to you, but maybe some day I can prove myself your friend. Young soldiers often need friends.” His eyes twinkled and his smile widened. In spite of his appearance and his proposition, something winning had suddenly appeared in the manner of this man. Dick found himself shaking hands with him. “Good-bye, Mr. Mason,” said Watson. “It may be that we shall meet on the field, although I shall not be within range of the guns.” He left the lobby of the hotel, and Dick was rather puzzled. It was his first thought to tell Colonel Winchester about him, but he finally decided that Watson's own advice to him to keep silent was best. He and Colonel Winchester took the train from Washington the next day, and on the day after were with Pope's army on the Rapidan. Dick detected at once a feeling of excitement or tension in this army, at least among the young officers with whom he associated most. They felt that a storm of some kind was gathering, either in front or on their flank. McClellan's army was now on the transports, leaving behind the Virginia that he had failed to conquer, and Pope's, with a new commander, was not yet in shape. The moment was propitious for Lee and Jackson to strike, and the elusive Jackson was lost again. “Our scouts discover nothing,” said Warner to Dick. “The country is chockfull of hostility to us. Not a soul will tell us a word. We have to see a thing with our own eyes before we know it's there, but the people, the little children even, take news to the rebels. A veil is hung before us, but there is none before them.” “There is one man who is sure to find out about Jackson.” “Who?”
