Ngorongoro and the Serengeti do not yet appear, but the whole of the country from north of Lake Natron to south of the Pare Mountains is assigned to ILMASAI. To bring out the salient points, the Survey and Mapping Division of the Ministry of Lands, Housing and Urban Development undertook an enlargement (times 2) which accurately reproduces the features which are of particular concern to this story, but omits many others. has kindly provided a photo copy of the relevant portion of the map, exhibited as map 2B, stating that this is the best that can be made. The map itself has never been published but is in the possession of the Royal Geographical Society, London. Their representation of this lake, depicted in Map 2A, suggested a slug, hence the popular name of the map. From the information at their disposal it appeared that one huge lake lay at the centre of the area. This is a comprehensive endeavour by the missionaries Krapf and Erhardt to depict large areas of East and Central Africa including the Great Lakes.
