Bruno, who had been told to keep out of sight, joined them after they had gone some distance. He acted dejected and dispirited, and if he could have talked would have asked the meaning of it all. Time and time again he had given warning of the approach of guerrillas, only to have his master meet them as friends. He had given notice of the approach of Duncan's party, and to his surprise nothing had come of it. He was a thoroughly disgusted dog, and walked along with drooping head and tail; but it only took a word from Harry to set him all right again. "We must turn north again at the first opportunity," said Lawrence. "This will put us back several miles." They had not gone far before they met a solitary guerrilla. He was one of Duncan's party, and had gone out of his way to visit a friend. He was halted, and explained who he was. "Ah, yes," said Lawrence; "your company is just ahead. We left it only a few moments ago." "Whar be yo' goin'?" asked the fellow. "Back to join Poindexter, where we belong. I was carrying a message to Porter from Poindexter, but on meeting Duncan I gave it to him, so we are on our way back." The fellow had sharp eyes, and Lawrence noticed that he was scrutinizing his party closely, and when he saw Harry, who had been a little in the rear, and just now came up, he started perceptibly, but quickly recovered himself, and exclaimed, "I must be goin'." Putting spurs to his horse, he rode rapidly away. Harry gazed on his retreating figure, his brow wrinkled in perplexity. Suddenly he cried: "Captain, I know that fellow, and I believe he recognized me. If he did, we are going to have trouble." "Are you sure?" asked Lawrence, startled. "Quite sure. I arrested him near Paris a couple of months ago, and he gave his parole. I had hard work to keep Bruno from throttling him. Where is Bruno?" "There he comes now," said Lawrence, "and he seems to be greatly excited." Bruno was indeed greatly excited, and he ran around Harry, growling, and then in the direction the fellow had taken, looking back to see if Harry was following. "Bruno knows him, too," said Harry. "He never forgets. If that fellow saw Bruno, it is indeed all up. He will tell Duncan, and we will have a fight on our hands as sure as fate." "By hard riding we can reach Mexico and avoid the fight," said Lawrence; "but I don't like the idea of running away." "Nor I," said Harry. "Even if the fellow knew me, Duncan may not follow us." "What do you think, Dan?" asked Lawrence. Dan took a chew of tobacco, as he always did when about to decide anything weighty, and then slowly remarked: "Don't like to run until I see something to run from." "That's it," cried Lawrence. "It is doubtful if Duncan follows us at all. If he does, it will be time enough to think of running."
