In the conversation that followed, the trader confirmed the statements of Fred in every particular. It was a good bit of tact on the part of Mr. Farrington to draw Rexford out as he did, for not only did it prove that Fred had told the truth, but the merchant's manner gave him some ideas which he thought would prove valuable in solving the money mystery. When Fred called at the mill to see Mr. Farrington at the time appointed, the latter greeted him cheerfully. "Good morning, my boy; I see you are on time," looking at his handsome gold watch. "Yes, I believe so; I always try to keep my appointments." "That is in your favor." "Thank you, Mr. Farrington. I hope it is. But have you seen Mr. Rexford?" "Yes, I just came from there." "Did you learn anything new?" asked Fred, with breathless interest. "No; not exactly new." "I suppose you went over the matter with Mr. Rexford?" "Yes, he told the story practically as you gave it, but during our conversation I gathered a few points that may be of service to us." "What is your theory, Mr. Farrington?" "As it is little more than a suspicion at best, I think it would be wiser to keep it to myself at present." "But if I knew it couldn't I help you?" "No, I think not, and it might even make matters worse. The only way to work up this affair is to do it quietly. If others find out what is going on, perhaps we shall never be able to locate the money. Besides, it wouldn't do for it to get out that I am working up your case." "But I would say nothing about it," put in Fred, whose curiosity and interest were both excited as he thought that perhaps Mr. Farrington had the secret that would free him from suspicion and prove his honesty. "I don't doubt that in the least; but for good reasons of my own I will say nothing of my theory until I test it thoroughly, though it may take a long time. If it should prove to be the true solution of the mystery, I will then tell you all about it." Fred colored a little at this, for he had grown somewhat sensitive now, and said earnestly: "I hope, Mr. Farrington, you too don't suspect me. It almost seems----" "Oh, no, my boy," interrupted his good friend, "don't worry about that. My suspicions run in a totally different direction." "I am very glad to hear you say so, for I didn't know but Mr. Rexford had convinced you that I took the bill." "No, indeed; I believe you are innocent, and I shall do all I can to aid you." "You are very kind to me, and I thank you sincerely." "I am glad to help you, Fred. It is my duty to do all the good I can." "And you are always helping some one," replied Fred gratefully. "Now that I can do nothing to clear up this mystery, I would like to get to work. Can you give me anything to do?" he continued.
