"Well, between you and me, there's really nothing to raid. You are there to intercept messengers. They must call at the wells. Of course you have only just come out, but you probably understand already enough about the conditions of this country to know that there is a great deal of disaffection about, and that the Khalifa is likely to try and keep in touch with his adherents. Then, again, Senoussi lives up that way"--he waved his cigarette to the westward--"the Khalifa might send a message to him along that route. Anyhow, your duty is to arrest every one coming along, and get some account of him before you let him go. You don't talk Arabic, I suppose?" "I am learning, sir." "Well, well, you'll have time enough for study there. And you'll have a native officer, Ali something or other, who speaks English, and can interpret for you. Well, good-bye--I'll tell the Chief that you reported yourself. Get on to your post now as quickly as you can." Railway to Baliani, the post-boat to Assouan, and then two days on a camel in the Libyan Desert, with an Ababdeh guide, and three baggage-camels to tie one down to their own exasperating pace. However, even two and a half miles an hour mount up in time, and at last, on the third evening, from the blackened slag-heap of a hill which is called the Jebel Kurkur, Hilary Joyce looked down upon a distant clump of palms, and thought that this cool patch of green in the midst of the merciless blacks and yellows was the fairest colour effect that he had ever seen. An hour later he had ridden into the little camp, the guard had turned out to salute him, his native subordinate had greeted him in excellent English, and he had fairly entered into his own. It was not an exhilarating place for a lengthy residence. There was one large bowl-shaped, grassy depression sloping down to the three pits of brown and brackish water. There was the grove of palm trees also, beautiful to look upon, but exasperating in view of the fact that Nature has provided her least shady trees on the very spot where shade is needed most. A single widespread acacia did something to restore the balance. Here Hilary Joyce slumbered in the heat, and in the cool he inspected his square-shouldered, spindle-shanked Soudanese, with their cheery black faces and their funny little pork-pie forage caps. Joyce was a martinet at drill, and the blacks loved being drilled, so the Bimbashi was soon popular among them. But one day was exactly like another. The weather, the view, the employment, the food--everything was the same. At the end of three weeks he felt that he had been there for interminable years. And then at last there came something to break the monotony.
