The Geology of Southwestern Uganda

In order that the reader may properly judge the scope of the information given in this paper it is necessary to explain the manner in which it has been compiled and the facts which have led to its publication. It is the fruit of eighteen months' geological exploration and prospecting in the service of the Central African Exploration Company (a subsidiary of the Billiton Company), which in Co-operation with a British company acquired large concessions in southwestern Ugandaandin northwestern Karagwe. 1 Uganda, which tagether with Kenya Colony and Tanganyika Territory ) formspart of British East Africa, has an area of 244,000 square kilometres, of which 42,700 sq.km. is water, including the northern part of Victoria Nyanza with an area of 67,000 sq.km. This protectorate (cf. map I, drawn after the map I : I,ooo,ooo of Uganda Survey Dept. No. A 530) comprises three king­ doms, Buganda, Toro and Ankole, and some Crown lands divided into districts, the southwesternmost of which, Kigezi, with Kabale as its seat of European Administration, will be frequently mentioned. The first European to enter Uganda was Captain Speke, who reached Gon­ dokoro in I862 just as Sir Samuel Baker was preparing for his journey to the south. The names of these two explorers recall the times of arduous pioneer work in discovering the sources of the Nile, when such magnificent examples of courage and perseverance were shown and attentionwas drawn to those remote parts of Africa known to-day as British East Africa.
