Feb. 21st.-This morning Kamrasi was civil enough to allow us to quit the marsh, the mosquito-nest and fever-bed where we had been in durance, and we crossed to the other side of the Kafoor river, and quartered in M'rooli. I went to see him, and, after a long consultation, he promised to send me to the lake tomorrow. I immediately took off my sword and belt, and presented them to him, explaining that, as I was now convinced of his friendship, I had a pleasure in offering my sword as a proof of my amicable feeling, as I thus placed the weapon of self-defence in his hand, and I should trust to his protection. As a proof of the temper of the blade, I offered to cut through the strongest shield he could produce. This delighted him amazingly. I now trust to be able to reach the junction of the Somerset with the M-wootan N'zige at Magungo, and from thence to overtake Ibrahim at Shooa, and to hurry on to Gondokoro, where a boat will be waiting for me from Khartoum. "Ibrahim and his men marched this morning, on their return to Karuma, leaving me here with my little party of thirteen men. "Should I succeed in discovering the lake I shall thank God most sincerely. The toil, anxiety, the biting annoyances I have daily been obliged to put up with in my association with the Turks, added to our now constant ill-health, are enough to break down the constitution of an elephant. Every day I must give!--to the Turks, give!--to the natives, give! If I lend anything to the Turks, it is an insult should I ask for its return. One hasty word might have upset my boat; and now, for twelve months, I have had to talk, to explain, to manage, and to lead the brutes in this direction, like a coachman driving jibbing horses. Hosts of presents to Ibrahim, combined with a vivid description of the advantages that he would secure by opening a trade with Kamrasi, at length led him to this country, which I could not have reached without his aid, as it would have been impossible for me to have procured porters without cattle. The porters I have always received from him as far as Karuma for a payment of six copper rings per head for every journey. I have now arranged that he shall leave for me thirty head of cattle at Shooa; thus, should he have started for Gondokoro before my arrival at Shooa, I shall be able to procure porters, and arrive in time for the expected boat. "Up to this day astronomical observations have been impossible, a thick coat of slate colour obscuring the heavens. Tonight I obtained a good observation of Canopus, giving latitude 1 degree 38 minutes N. By Casella's thermometer I made the altitude of the Somerset at M'rooli 4,061 feet above the sea, showing a fall of 65 feet between this point and below the falls at Karuma in a distance of 37 miles of latitude.
