This map, which was published in 1895, was intended, first and chiefly, to illustrate the work done by Mr. Selous while in the service of the South African Company; and, secondly, to embody, as far as possible, the knowledge possessed of the entire region extending from Fort Salisbury to the northward as far as the Zambezi, and to the eastward as far as the lower Pungwe. Mr. Selous's manuscript originals, deposited in the map room of the Royal Geographical Society, comprise a compass survey, showing the routes during a year's employment in the service of the British South African Company, September 1, 1890, to September, 1891, on a scale of 1:255,000; a sketch map, showing the route of the Manika Mission from Fort Charter to Umtassa's and thence to the camp near Mount Wedza, and also the routes taken by Mr. Selous from the camp near Mount Wedza to Makoni's, Mangwendi's, Maranka's, and back to Makoni's, on a scale of 1:255,000; a sketch of routes from Umtali to Mapanda (Pungwe) and back, in 1891, on the same scale; a sketch of Mashonaland, showing tribal boundaries, on the same scale; a rough survey map of the countries ruled over by the Makorikori chiefs, for which a mineral concession had been granted to the Selous Exploration Syndicate, on a scale of 1:210,000; and about thirty sheets of manuscript maps and rounds of angles, utilized in the compilation of the first four maps of this list. Although Mr. Selous did not determine latitudes or longitudes, his long-distance compass bearings enabled him to lay down a network of triangles connecting Fort Salisbury with Masikesi. These triangles included Fort Charter, Sengedza, and Mavanka's in the south, Mount Mtemwa in the north, and Mount Dombo in the east; and it turns out that the distance between Fort Salisbury and Masikesi, as resulting from this triangulation, differs to the extent of only about a mile from that obtained by careful astronomical observations made at the two terminal points. The greater part of Mr. Selous's compass bearings were taken during the rainy season, when the air was very clear and landmarks could be seen at great distances. Mr Selous's determinations of altitude were not so accurate, and those obtained with the aneroid were characterized by himself as "of little value."
