4to. 65 pp. With 13 numbered plates, including one folding map of mineral deposits and suitable sites for dams on the Gold Coast. Original printed wrappers. Stapled. First bulletin of the Geological Survey of the Gold Coast in British West Africa (now Ghana). Prepared by Albert Kitson, the director of the Survey, who travelled around the colony by train and bicycle and discovered sizeable mineral deposits including bauxite and manganese. Enriched with compelling photographic material of the Insuta-Dagwin manganese deposit, ore and bauxite deposits at Mount Ejuanema, and diamond mining in Abomoso, particularly striking for depicting the exploitation of indigenous workforce in the interest of a colonial power. - Established in 1913, the Gold Coast Geological Survey carried out the first reconnaissance-traversing of the country during which the manganese, alluvial diamond and bauxite deposits, all observable at the surface, were discovered. This type of work was continued between 1925 and 1939, when detailed maps of the gold fields were prepared and Bulletins and Memoirs were published. The increased price of gold in 1931 gave a great impetus to gold mining and prospecting, and for some years the Geological Survey was chiefly concerned with the development of this industry. A Water Supply Section was started in 1937, but lapsed in 1942 after many wells, dams and ponds had been constructed in the Northern Territories. - Very well preserved. - From the collection of the Dutch geologist Hendrik Albertus Brouwer (1886-1973); his ownership stamp to cover and title-page. - OCLC 16963396.
