R. T. Williams, The Cape to Cairo Railway from the Point of View of African Development: A Paper Read Before the Central Asian Society, 5th April, 1922 (London, 1922).

Livingstone said that African civilization would come through commerce and industry. The African native is gradually being changed from a warrior to a worker. The pioneer of Katanga exploitation was an Englishman, Robert Williams, the moving spirit in the construction of the Benguella Railway from Lobito Bay to the Katanga. An extensive mineralized area has been discovered by prospectors of the Congo-Nile Syndicate, which belongs to the Tanganyika Concessions Group. The discovery is described as of alluvial gold, which is said to have been traced in several rivers. The story of its inception and the difficulties encountered by international rivalries is one of extraordinary interest. In the far future, when Africa becomes civilized and industrialized, internal railways as in Europe will, no doubt, become important and remunerative means of transport, conveying the products and manufactures of one region to another.
