Edgar made very rapid progress with the language. It was well for him that he had picked up a few words and sentences at Suakim and Cairo, for this enabled him to make far more rapid progress than he would have done had he been ignorant of the language. He attempted to keep up a constant conversation with the negro, and although the latter often went into screams of laughter at his mistakes he was ready to help him, correcting his errors and repeating sentences over and over again until he was able to pronounce them with a proper accent. In two months he was able to converse with tolerable fluency, and the sheik was meditating broaching the subject of his conversion to him when an event occurred that for a time gave him other matters to think of.

One morning when the encampment woke Hamish was found to be missing, and it was ere long discovered that the best camel in the encampment had been stolen, and that two water-skins had been taken from the sheik's tent, and a perfect hubbub arose in the village when this became known. The sheik seizing a stick fell upon the other negro and showered blows upon him, exclaiming that he must have known of and aided his companion in his flight, although he declared he had not the least idea of his intentions. As soon as his first burst of rage was over the sheik ordered four of the best camels to be saddled and water-bottles to be filled.

"The fellow must be mad," he said as he walked up and down before his tent; "he must know that he cannot escape; he would be known as a slave by the first people he comes upon, and it would only be a change of masters, and he would be long before he finds one so gentle as I have been with him."

"I do not think he has gone away to make a change in masters," Amina said. "It is worse than that, I fear."

"What is it, Amina? What do you mean?"

"I fear that he has made for Khartoum to report that you have a white slave here. He hates Muley, and I think that it is to obtain vengeance on him that he has fled."

"You are right, Amina; that is what the son of Sheitan intends to do. Quick! bring up those camels," he roared.

Three of the men were ordered to accompany him. Then he gave orders that the rest of the camels should be loaded at once with his goods, the valuables of the village, and a portion of the crops, and that they should start without delay to the oasis of Wady El Bahr Nile, or the valley of the Dry River, two days' journey to the west, driving with them the herd of goats.

"If I do not catch him we must break up the donar," he said, "and all who do not wish to be found here by the Mahdi's men had best be in readiness to start when we return. Let half a dozen men and women go to the wady to look after the goats and guard the property. The camels must be brought back as soon as they get there."

Ten minutes later he and his three companions had disappeared from sight over the brow of the nearest sand-hill, while all in the encampment were busy in preparing for their departure. A camel was allotted to each of the ten tents of which the camp consisted; three camels were claimed by Amina for the sheik's possessions; the remaining six were to carry the food. All who were not engaged were at once set to work gathering the maize that was fit to pluck and cutting and tying up into bundles the forage for the camels.
