"An old voucher," he thought; and unfolded it to see if it were worth keeping. To his surprise it was dated Nov. 17, 1913, and evidently belonged to the series which he had examined in connection with the accounts of the past year. But that series had corresponded exactly with the entries in the stock book--or had he made a mistake? To reassure himself he got out the file, turned to the vouchers for November, and once more compared them with the book. There was no discrepancy. The book showed that on Nov. 17, 1913, a consignment of 1000 kilos was shipped on board the _Hedwig von Wissmann_, and there was a voucher corresponding. The voucher he had just found was for a consignment of 1000 kilos. This was odd. The numbers on the two vouchers were consecutive: clearly they did not refer to the same consignment. Yet there was only one entry of that date in the book. If one had been a duplicate or a carbon copy of the other, the matter would have been easily explicable; but both were originals, and written in the same clerkly hand. Troubled, for it was impossible to crush down a suspicion, Tom put the voucher into his pocket, and went out into the plantation. "I’ll write to Bob to-morrow," he said to himself. At the back of his mind there was the feeling that he might have more to say than he had expected. Reinecke was in good spirits when he returned about sunset. "I’ve just made an excellent contract with a dealer representing a new house," he said. "He’ll take all next season’s crop, at a good price. I hoped your visit would bring us good luck, and this is the best." "Capital news," said Tom. The German’s manner was so frank and cordial that he was almost ashamed of his suspicion. "By the way, I found this to-day: it was stuck between two drawers. Is it any good?" He handed Reinecke the voucher, folded. The German opened it, and said instantly, with a smile-- "At last! I wondered what had become of it. It is a voucher I lost, and I got the shipping clerk to give me another. You found that on the file all right?" "Yes." "You don’t know how I worried about that lost voucher. And you found it wedged between the drawers? Extraordinary way things have of disappearing! Well, we don’t want it now. But I’m glad you found it." He tore it across and threw the pieces into the waste-paper basket. "Now for dinner," Reinecke went on. "I hope your appetite is as good as mine. And how have you put in your time to-day?"
