"Yes, we are to retire to Wady Halfa."

"What! and abandon Dongola?"

Rupert nodded.

"Then I call it a beastly shame. More than that, I call it a downright dishonourable action!" Easton said hotly. "Here we are going to abandon a town of some twenty thousand inhabitants to these fanatics. Not only that, but to give up to their vengeance all the tribes between Wady Halfa and Metemmeh who have trusted in our promises, have thrown in their lot with us, and have for the last four months been doing all our transport. Our fathers used to be proud to call themselves Englishmen, but, by Jove, there is very little reason for us to be. That Boer business was shameful and humiliating enough, but this is worse still. I don't say that we are bound to go on to Khartoum, although it would be the best and cheapest and most satisfactory mode in every way of settling this Mahdi and ensuring order in the Soudan; but I do think that we are bound to hold the river from Korti downwards to protect the tribes that have been friendly to us, and to save this town from ruin and desolation. Not only this town, but all the peaceful villages down the river. Besides, so long as we are here the Arabs will see that the Mahdi is not all-powerful, and may sooner or later rise against his tyranny. Well, I never thought this campaign was going to end in the disgraceful abandonment of the Nile Valley from Korti to Wady Halfa. However," he went on, checking himself suddenly, "it is of no use talking of that now; we have got to think about your expedition, which to us three is a far more important business. How does your Arabic get on?"

"Fairly well. I don't say that I can talk a great deal, but as I have learnt it by ear I speak with a fair accent, at least so Ibrahim says. I have taken particular pains with what you may call salutations, such as one man gives another as they pass each other on a journey, or what one says on entering a house or a village. I can ask for food all right, return thanks for hospitality, ask the way, and all that sort of thing; and Ibrahim said that in all these things I could pass very well as a native, especially as there are slight distinctions and differences between the language of the various tribes. They are a very mixed people, of Arab, Egyptian, and Negro blood. So that as far as it goes my language will pass, and of course every day I travel I shall improve. I intend, as I have said, to pretend to be dumb whenever we come across strong parties of strangers, and my sheik will shield me as much as possible by sending me out to look after the camels and to gather wood and to fetch water, or on other business, whenever we are with strangers. I really think, Easton, I have a very fair chance of getting through it without being found out. Major Kitchener tells me that the sheik only has two or three of his tribesmen with him, and that he has no doubt picked men he can trust to hold their tongues, otherwise he would get into a mess when he went back again among his people. Of course the men will be promised a reward also if I get safely through. The trouble on my mind is more the difficulty there will be in finding Edgar and getting him off than about myself. In the first place there is no saying as to the direction in which the men who have got him have gone. They have probably gone to some out-of-the-way place, so as to be out of the way of the Mahdi's people.

"Ibrahim tells me that there are no people more pig-headed than these Arabs, and if they once make up their mind to a thing nothing will turn them. That is all the better, as far as the risk of Edgar falling into the hands of the Mahdi is concerned, only it makes it all the more difficult to find him. There is no saying where he may have moved to; he may have gone far south of Khartoum, he may have pushed away near the borders of Abyssinia, he may be within a few miles of Suakim, he may be in the desert we crossed. I don't disguise from myself that it is likely to be a long search; but that is nothing if I am but successful at last. Of course the great thing will be to endeavour to pick up a clue near Metemmeh.

"The tribe is a very scattered one, and is to be found dispersed among other tribes all the way from Berber to Khartoum on the eastern side of the river, and I hear that there is a branch of it who live in the desert to the west. Well, it is likely that Edgar's master will have stopped in some of these villages among his own people, if only for a few hours, and it is from them I hope to get some clue as to the general direction at least in which they were travelling. Unless they disguised Edgar, and wrapped him up as a woman, or something of that sort, the fact of a white prisoner passing through is certain to have caused talk. However, it is impossible to say where or how I may find a clue.

"At any rate I shall stick to it. I shall tell my father, that as it may take me a year to find Edgar he need not even begin to feel anxious until the end of that time, and that as I shall be continually improving in my knowledge of the language, the risk of detection will become less and less every month, and that I anticipate no difficulty whatever when the time comes in passing down to Suakim or Massowah, or should any difficulty arise in that direction, in either working down to Wady Halfa or through Abyssinia."

They sat and talked until far into the night, and then lay down for a few hours' sleep, and at daybreak Rupert said good-bye to his friends and took his place in the boat, which, spreading its sails, rapidly made its way up stream. The two friends stood for a long time looking after it.

"By Jove, Clinton has turned out a fine fellow," Skinner said; "a grand fellow! I hardly thought he had it in him. Of course I knew he was plucky, and all that sort of thing; but this is a tremendous undertaking."
