Zaki had not much to do, but Gregory was well satisfied with the selection he had made. He looked after and groomed the horse, saw that the native with the camel took care of it, and went down regularly to the river to water it every evening, while he himself did the same with the horse. He always had a jug of cold tea ready for Gregory, whenever he came in, and the floor of the tent was kept scrupulously clean. Zaki's only regret was that he could not do more for his master, but he was consoled by being told that the time would soon come when he would be more actively engaged.

From the first day of his arrival, Gregory was kept fully employed. Sometimes he assisted the officer of the Intelligence Department, in interviewing fugitives who had arrived from Berber and other points on the river, from Kordofan, or from villages on the White Nile. Sometimes he carried messages from the General to the officers in command of the two Egyptian brigades. He had to listen to disputes between natives returning to their homes, from which they had been driven by the Dervishes, and those they found in possession of their land. He took notes of the arguments on both sides, and submitted them to the General for his decision.

The work would have been trifling in any other climate, but was exhausting in the sweltering heat of the day, and he was not sorry when the sun sank, and he could take off his khaki tunic and go down to the river for a swim.

One evening, as they were sitting after dinner, General Hunter said:

"It is very annoying that, while these natives making their way down the country are able to tell us a good deal of what is taking place on the Nile, from Omdurman down to Metemmeh; and while we also get news of the state of things at Berber and Abu Hamed; we know nothing whatever of Mahmud's intentions, nor indeed anything of what is doing at Metemmeh, itself, since it was captured by the Dervishes and, as we heard, the whole population destroyed.

"Of course, Mahmud has the choice of three courses. He can stay where he is, he can march his whole force to Berber, or he can advance against us here. I don't suppose that he has any idea of the progress the railway is making from Wady Halfa. He may have heard, and no doubt he has heard, that we are making a road of some sort across the desert in the direction of Abu Hamed; but of the capabilities of the railway he can form no idea, and may well believe that the march of an army, across what is practically a waterless desert, is a matter of impossibility.

"On the other hand, he knows that we are gathering a considerable force here; and, with his limited knowledge, doubtless supposes that we are going to cross the Bayuda desert, to Metemmeh, as the Gordon relief column did; or that, if we are not coming that way, we intend to follow the river bank up to Berber. Unquestionably his best course, if he considers, as we may be sure he does, that the force under his command is strong enough to crush us here, would be to push across the desert, and fall upon us before reinforcements arrive. But it is reported, and I believe truly, that the Khalifa, his father, has positively refused to let him do so; still, sons have disobeyed their fathers before now.

"There is, it is true, the difficulty of water; but that is not so serious, in the case of a Dervish force, as it is with us. In the first place, they can march twice as far as we can. In the second place, they are accustomed to go a long time without water, and are but little affected by the heat. Lastly, they have nothing to carry except their weapons, a few handfuls of dates, and their water gourds. Still, we know that the forces that have, one after another, arrived here have been greatly weakened by the journey. However, Mahmud may attempt it, for he must know, from his spies here, that we have at present no such land transport as would be required, were we intending to advance across the desert. He may, therefore, move at least a portion of his force to Berber; trusting to the fact that, even did we make an advance south from here, with the intention of cutting off his retreat to Khartoum, he would be able to reach Metemmeh before we could get there.

"Undoubtedly, a British general, if commanding a force constituted as Mahmud's is, would make a dash across the desert and fall upon us; unless, indeed, he felt certain that, after the difficulties we encountered last time we attempted to take the desert route, we should be certain to advance by the river, step by step, continuing the policy that we have followed since we began to push forward from Assouan.

"Mahmud is in a very difficult position. He is controlled by his father at Khartoum. Among those with him are many important Emirs, men of almost equal rank with himself; and he could hardly hope that whatever decision he might personally arrive at would be generally accepted by all; and those who opposed him would do so with all the more force, as they could declare that, in making any movement, he was acting in opposition to his father's orders.
