I never saw a more atrocious countenance than that exhibited in this man. A mixed breed, between a Turk sire and Arab mother, he had the good features and bad qualities of either race. The fine, sharp, high-arched nose and large nostril; the pointed and projecting chin; rather high cheek-bones and prominent brow, overhanging a pair of immense black eyes full of expression of all evil. As he approached he took no notice of us, but studiously looked straight before him with the most determined insolence. The fate of the expedition was, at this critical moment, retrieved by Mrs. Baker. She implored me to call him, to insist upon a personal explanation, and to offer him some present in the event of establishing amicable relations. I could not condescend to address the sullen scoundrel. He was in the act of passing us, and success depended upon that instant. Mrs. Baker herself called him. For the moment he made no reply; but, upon my repeating the call in a loud key, he turned his donkey towards us and dismounted. I ordered him to sit down, as his men were ahead and we were alone. The following dialogue passed between us after the usual Arab mode of greeting. I said, "Ibrahim, why should we be enemies in the midst of this hostile country? We believe in the same God, why should we quarrel in this land of heathens, who believe in no God? You have your work to perform; I have mine. You want ivory; I am a simple traveller; why should we clash? If I were offered the whole ivory of the country, I would not accept a single tusk, nor interfere with you in any way. Transact your business, and don't interfere with me: the country is wide enough for us both. I have a task before me, to reach a great lake-- the head of the Nile. Reach it I will (Inshallah). No power shall drive me back. If you are hostile, I will imprison you in Khartoum; if you assist me, I will reward you far beyond any reward you have ever received. Should I be killed in this country, you will be suspected; you know the result; the Government would hang you on the bare suspicion. On the contrary, if you are friendly, I will use my influence in any country that I discover, that you may procure its ivory for the sake of your master Koorshid, who was generous to Captains Speke and Grant, and kind to me. Should you be hostile, I shall hold your master responsible as your employer. Should you assist me, I will befriend you both. Choose your course frankly, like a man--friend or enemy?"
