He had already discovered that the little old Shereef Imhammed had been often employed by the King of Fezzan as his Factor in the Slave Trade; and in that capacity had travelled to Bornou and different parts of Nigritia; and he now determined to cultivate his friendship with double solicitude, and by occasional presents and frequent conversation, to draw from him an account of the countries which he had seen. With this view he, one evening, took from his pocket his map of Africa, and after satisfying the Shereef’s curiosity as to its nature and use, told him that he once intended it as a present to the King of Fezzan; but, that having discovered in it several mistakes, he now proposed to draw another that should be more correct. The Shereef replied, that the King would be highly gratified with such a present. Mr. LUCAS said, that if he would assist him with an account of the distances from place to place, in such parts of the country as he had visited, and with their names in Arabic, and would also satisfy him as to such questions as he should ask, he would prepare _two_ corrected copies of the map, and would give one of them to the King and the other to himself. The Shereef was delighted with the proposal; and they immediately retired to a sand hill at some distance from the tent, that their conversation might be unreserved and uninterrupted. Many successive days were employed in the same manner; and as Mr. LUCAS wrote down, at the time, the information which he obtained, he was soon possessed of such an account of Fezzan, Bornou, and Nigritia, especially of the two former, as much diminished the chagrin of his own disappointment. One afternoon, as they sat together on the customary hill, they were suddenly disturbed by the loud screams and dismal howlings of all the women of Mesurata—a mode of alarming and collecting the men, which is always practised among the Arabs, on the approach of thieves, or of an invading enemy. In a few minutes the townsmen were under arms, and together with the Shereef Fouwad, the other Fezzaners, and Mr. LUCAS’s Black, went hastily on to the place where the Rebels were said to have appeared:—there they found that the women had been deceived. It seems an ass had strayed into a field of barley; and as the owner of the corn, who was armed, and happened to pass by at the time, went into the field to drive out the animal, the women mistook him for one of the Rebels, and conceiving that many more were concealed, (for they often come down from the mountains to steal the cattle) had given the usual alarm. In a few minutes, Mr. LUCAS and the old Shereef, who had both continued on the hill, observed the Fezzaners coming sulkily back, and cursing the women for so foolish a disturbance, whilst the townsmen, on the contrary, fired their pieces, and rejoiced in their disappointment as much as if they had conquered an army.
