Mr. Billy went to Richmond, as he had said he intended doing, but he did not remain there an hour. He went to the cashier of a bank, a gentleman with whom he was well acquainted, got from him a letter of introduction to a prominent man in Philadelphia, and left for that city on the first train. Arriving in Philadelphia about nine o'clock the next day, Mr. Billy ate a hasty breakfast and proceeded to the little collegiate institute in which Robert had once been a professor, as the reader will remember. Introducing himself to President Currier he asked for a private interview, and was invited for the purpose into Dr. Currier's inner office. "I believe, doctor," he said, after telling that gentleman who he was, "that there was something due Professor Pagebrook on his salary at the time his connection with this college terminated, was there not?" "Yes, sir; there was about three hundred dollars due him, if I remember correctly, but it has been paid, I think." "Have you any way of ascertaining precisely how and when?" asked Billy. "Yes; my own letter-book should show. Let me see," turning over the leaves, "Ah, here it is. A draft for the amount was sent to him by letter on the eighth of November, addressed to ---- Court House, Virginia." "Thank you," said Billy. "The draft, I suppose, was regular New York Exchange?" "Of course." "Would you mind telling me from what bank you bought it, and to whose order, in the first place, it was made payable? Pardon my asking such questions, but I need this information for use in the cause of justice." "O you need offer no apology, I assure you, sir," returned the president. "I have nothing to conceal in the matter. The draft was drawn by the Susquehanna Bank, and to my order, I think. Yes, I remember indorsing it." "Thank you, sir," said Billy. "You are very courteous, and I am indebted to you for information which I should have found it difficult to get from any other source. Good morning, sir." Leaving the college, which was situated in one of the suburbs, Mr. Billy took a carriage and drove into the city. There he delivered his letter of introduction, and secured from the gentleman to whom it was addressed a personal introduction to the cashier of the Susquehanna Bank. To this latter person he said: "I am looking up evidence in a case, and, if I am not greatly mistaken, you can help me in an effort to set a wrong right. On the eighth of last month you sold a draft on New York for three hundred dollars, payable to the order of David Currier. Now, in the ordinary course of business I suppose that draft has been returned to you after payment." "Yes, if it was paid before the first of the month. We settle with our New York correspondents once a month. I'll look at the last batch of returned checks and see." "Thank you. I should be glad to see the indorsements on the paper, if possible."
