The next day continuing their course, they at last sailed into the bay, which forms the northeastern extremity of the Victoria Nyanza. The eastern side of this bay is lined with bold hills and ridges, but at the extreme end where the Tagama River comes in, the country is flat. The expedition now began to move westward in its slow circumnavigation of the lake, and came at length to Muiwanda. Here they found the savages friendly, and they landed and obtained from them, at fair prices, such provisions and vegetables as they desired. They also gave Stanley all the information they could of the neighboring country. They told him that the name of the bay in which they rode, and which was the extreme northern limit of the lake, was Baringo. They had evidently not been great travelers or much visited by any tribes living away from their own coast, for they said that they had never heard of any other lake, great or small, except that one--the Nyanza. Considering that this whole central region of Africa is dotted with lakes, and that the Tanganika, an inland sea, is not three hundred miles distant, it is evident they must live very much isolated from any but their own people. Stanley had now surveyed the southern, eastern and northeastern shores of the lake, and had taken thirty-seven observations and entered almost every nook and cove of this vast body of water. He had corrected the map of Speke, made on the report of the natives--proved that he was wrong in his latitude of the lake, and taken such ample notes that he could make out an accurate chart of that portion he had thus traversed. He makes the extreme eastern point of the lake end in 34° 35' east longitude, and 33' 43" north latitude. After he had finished his exploration thus far, Stanley went over his route, to gain a general knowledge of the country, the location and approximate size of the various districts, and general character of the inhabitants. The north shore he found indented with deep bays, and so completely land-locked, that they might easily be mistaken for separate lakes, while the islands clustered so thickly and closely to the shore that unless thoroughly examined, would be taken for portions of the mainland. But Stanley has traced it out so plainly, that the outline of the shore is as distinct as that of Lake Ontario. CHAPTER XIII. EXPLORATION OF THE VICTORIA NYANZA.
