"That's to scare vultures away until our return," said Reinecke. "In the rainy season myriads of flies would be at the carcase already, but in this dry weather it will probably not suffer much before the niggers get back to cut it up. Hyenas and other scavengers don't prowl till night. Now let us get on."

The negroes, whose pleasure is always rather in the quarry than in the chase, were delighted at having secured, without trouble to themselves, a quantity of fresh pork to carry home, and went on with alacrity to the stream a few miles away. Here, in the course of a couple of hours, the two white men had shot as many geese, quail, and guinea-fowl as the negroes could conveniently carry slung about their bodies, with the prospect of the addition of a good many pounds of hog's flesh later. Tom was disappointed of his half-cherished hope of bagging a hippo; but his morning's sport had been sufficiently exciting to form an interesting part of his next budget of news for his brother.

A negro carried the mail to Bismarckburg once a week, and Tom had already dispatched his first letter, giving a description of the plantation and a running account of his experiences so far. He had confined himself to statements of fact, saying nothing about the problems he found himself faced with--the character of Reinecke and the conditions of the negro labour. Until he should have arrived at definite conclusions on these matters he felt that it would be unwise to trouble his brother with them.

In his second letter he related further sporting expeditions, in some of which he had been accompanied by Reinecke, in others only by Mirambo and other natives. He had shot several hartebeeste and waterbuck, which Mirambo was accustomed to skin and cut up on the spot. On these occasions Tom was tempted sometimes to question the negro directly about the conditions of his employment; but he was held back by a sense of loyalty to Reinecke. Pending further light on the man himself, he would rely solely on his own observations.

It was at the end of the third week of his stay that the first really disquieting incident occurred. Reinecke had gone to Bismarckburg, and Tom, having time on his hands, had made up his mind to write a long letter home. Going to the desk to get some paper, he discovered that the drawer in which he had usually found it was empty, and he tried the drawer below. This, however, would not open fully: it stuck half way. He put his hand in, thinking that something had probably become wedged between the upper part of the drawer and the one above. It was as he had supposed. By pushing in the drawer a little, he was able to work out the obstruction, which turned out to be a paper, half folded and much creased. On the portion that was not folded down he saw a series of figures like the numbers on the vouchers which were kept on a file.

"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.
