The traders poured out a torrent of expostulation. They would see the goods again; doubtless they were of a better quality than they supposed; and so the bargain was recommenced, and after some hours a considerable portion of the goods that had been brought up were disposed of. In each case the traders arranged to come late in the evening with their servants to fetch away the goods they had bought.

"It would never do," one said, "to let it be known that we had money sufficient to make such purchases. It is only by assuming the greatest poverty that we can carry on our business unmolested, and only a few of the cheapest goods can be displayed to the eyes of the public, the rest being hidden away to be brought out privately for the benefit of some special customer."

The sheik was well pleased with the result of his traffic. The prices he had charged were five or six fold more than those that the goods had cost, and he sent out one of his followers to purchase a kid, which was presently converted into a stew. After this was eaten he went out with one of his followers, leaving the other to deliver the goods to their purchasers. When it became quite dark the traders arrived one by one, each with one or two porters to carry away the goods. These were paid for in cash drawn from buried hoards.

The sheik was late before he returned. He told Rupert that he had met a kinsman of his who was now an officer of the Mahdi, and had had a long conversation with him. "He believes in the Mahdi," he said, "and has faith that he is going to conquer the world. I told him that finding no traders would hire my camels I had this time brought up a load on my own account, and that it seemed to me there was money to be made if one could purchase some of the people who had been enslaved when the city was taken. He said that this could not be, that the greater part of the traders had been killed, and that all who remained were now zealous followers of the Mahdi. Lupton Bey was held as a slave by the Mahdi himself, and had to run before him when he rode. There would be no possibility of releasing him or the others in the Mahdi's hands.

"I inquired whether any of the Kaffirs who had come to Metemmeh had been taken prisoners. He said they had heard of but one, who was reported by a black slave to be in the hands of a petty sheik who was living at an oasis in the desert some nine days' journey from here. It had already been reported to the Mahdi that this man had taken a Kaffir prisoner at Metemmeh and had refused to give him up, and had escaped with the Kaffir in the night; and strict orders had been issued for his arrest, but nothing had been heard of him until the slave brought the news. The Mahdi sent off three officers and forty men on camels with orders to destroy everything, and to kill all they found with the exception of the sheik himself and his white captive, who were to be brought here to await his pleasure. They went, but though this is two months ago they have never returned.

"Another party was sent three weeks later to the place to order them to return instantly, but when they arrived there they found the oasis deserted. Two skeletons were found, but the sun and the vultures had done their work, and whether they had belonged to the troop that went or to the Arabs there none could say. It may be they found that this sheik and his party had travelled to El-Obeid or elsewhere and had pursued them, but so far no news has been heard of them and the whole matter is a mystery."

"What do you think has happened, sheik?"

"I know not what to think. My kinsman said that the black slave reported there were but twenty men in all with the sheik, and not more than half of these could be considered as fighting men, therefore they could not have resisted for a moment the force against them. It is possible they may have fled into the desert. The tribes know of wells whose existence is kept a secret from all, and it may be that such a well was known to the sheik and that he has made for it. It may be that the negro guide led the party in pursuit. Misfortune may have happened; they may have lost their way and all perished from thirst, though it would be strange indeed were none able to make their way back to the oasis."

"What think you we had better do, sheik? This gives us some indication at least of a direction in which my brother was taken."

The sheik sat for some minutes without answering. "It is difficult," he said at last; "this sheik El Bakhat is, as I have told you, a wanderer. I have heard of him though I have never met him. His father was a powerful sheik, but as a young man El Bakhat killed the son of another sheik of the same tribe and fled. Later on he gathered a few followers and was in the service of the slave-dealers who go down to the great lakes. Of late years, since Gordon broke up the slave-trade, he has returned at times and remained for weeks and sometimes for months in the part of the country occupied by his tribe, for it is so many years now since he killed his man that vengeance is no longer hot against him. He has the name of being a headstrong man, and indeed he must be so or he would never have embroiled himself with the Mahdi's people, for if he had been driven out of his oasis he would know that there is no safety for him anywhere near here; but where he has gone to no man could say. One might as well try to follow the flight of a vulture. He may have gone down near the coast; he may have made his way to the confines of Abyssinia; he may have journeyed away towards the lakes where Emin Pasha still rules in the name of Egypt. There is just one chance, he may be hiding in the desert, and before he starts on a long journey he may return to the oasis or may send a messenger to see if it is still occupied by the Mahdi's men. I think that our best chance is to proceed thither at once, and to wait there for a while to see if any come from him. If at the end of a fortnight or three weeks none come we can then decide in which direction to set out upon the search again."
