"But the Kaffir must do some work, Amina; he cannot have his food for nothing."

"Of course he shall work when I don't want him," the woman said, "but I shall find much for him to do. He will draw the water, he will fetch the fuel, he will grind the meal when I have anything else for the women to do. When he has done all I require of him, then he can go and work in the fields. It is no use your giving me a slave and then taking him away again."

"Well, well!" the sheik said, "do with him as you will; women are always pleased with novelties. You will soon get tired of having this Kaffir about the tent, but keep him if you will."

Amina took one of the large hospital kettles, and putting it into Edgar's hands pointed to the well which lay a hundred yards away and told him to fetch water. When he returned with it she bade him go out and gather fuel. The last order was by no means easy to execute. The Arab fuel consisted almost entirely of dried camels' dung, as the scrub very speedily becomes exhausted for a considerable distance from a camp. Edgar took a rough basket to which Amina pointed and was away for some hours, following the track by which he had arrived and making a circuit of the oasis, and returned with the basket piled up with the fuel.

Amina was evidently well satisfied with the result of his work, for fuel is one of the great difficulties of Arab life in the desert. She rewarded him with a calabash of meal.

"Has my lady anything more for me to do?" he asked when he had finished his food.

"Not now," she replied.

"Then I will go out and help the others in the field;" and he walked off to where the negroes were engaged in watering a plantation of maize. The process consisted of drawing water from the well in leathern buckets and pouring it into channels by which it was conducted to the plantation. The negroes looked at him sourly as he took hold of the rope attached to the long swinging beam that acted as a lever to bring the bucket to the surface, and one of them muttered in Arabic, "Kaffir dog!" Slaves as they were they despised this white Christian.

"Well, look here," Edgar said in English, letting go the rope, "the sooner we come to an understanding the better. I am not going to stand any nonsense from you fellows; and if you don't keep a civil tongue in your heads I will give you such a licking as will teach you to do so in future."

Although they did not understand his words they guessed the import of them, and the biggest of the men, a powerful negro, repeated the word Kaffir and spat upon him. Edgar's right arm flew out from his shoulder, the blow struck the negro on the nose, and in an instant he was upon his back upon the ground. His comrade stood for a moment stupefied, and then with loud yells ran towards the tents, leaving the negro to pick himself up at his leisure. Edgar continued the work of raising and emptying the bucket until the negro returned, followed by the sheik, his wife, and all the inhabitants of the village. By this time the negro who had been knocked down had risen to his feet and was roaring like a bull at the top of his voice, while the blood was streaming from his nose.
