"So much for the early history of the Albert N'yanza, which is known to the natives as the Luta N'zige. It is a hard word to pronounce, but if you throw 'n' and 'z' into one sound you can possibly manage it. In default of doing that you may call it 'Ziggee,' or fall back upon 'N'yanza,' which is much easier, and will do just as well; and if you are very old-fashioned you may drop 'N'yanza,' the African name for lake, and say you are steaming on Lake Albert, in Central Africa." [Illustration: SCENE ON THE SHORES OF LAKE TANGANYIKA.] Fred asked what was the relation between the Albert Lake and Lake Tanganyika. He had a general idea of the Victoria N'yanza and its geographical position, but wanted more information about the other. "We will get to that by-and-by," said the Doctor, in reply. "Tanganyika is still a mystery, as its outlet has not been fully determined, though it is pretty definitely settled that it discharges into the Congo, or Livingstone, and has no connection with the Nile. In fact, the surveys show that it is at a lower level than the Albert N'yanza, and consequently cannot flow into it; and as the Nile does not have any affluent of consequence north of here, it is impossible that roundabout stream from Tanganyika comes to it. We will talk more about that when we reach the scenes of the exploits of Livingstone and Stanley." As they had an abundance of time for circumnavigating the lake and reaching Magungo on the day appointed for meeting Frank, the Doctor concluded not to hurry the steamer, but make an early halt. So he told the captain to land at the first convenient spot, and they would remain there through the night. [Illustration: A LAKE VILLAGE.] It was at least an hour before sundown when the steamer was anchored near the shore, where a headland pushed out into the lake and afforded abundant water for safety. The small boat took Doctor Bronson and Fred to a little village close to the water. It consisted of several huts in front of a dense growth of papyrus-plants, and with a few palms rising from the firm ground beyond. The natives were alarmed at the visit of the strangers, and started to run away. They naturally took the party for a slave-stealing expedition, and concluded that their only safety was in flight. Our friends were accompanied by two soldiers who had been detailed to remain with them during their voyage, and return with the steamer to its point of departure. As a matter of precaution, these soldiers went wherever our friends did; and as they had seen a good deal of service, and were familiar with many of the African tribes, they were useful in numerous ways besides serving as escort.
