Isaac Frederick Marcosson,
An African Adventure
“ Before the advent of civilization the Katanga blacks dealt mainly in slaves and in copper.The real pioneer of development in the Katanga is an Englishman, Robert Williams, a friend and colleague of Cecil Rhodes, and who constructed, as you may possibly recall, the link in the Cape-to-Cairo Railway from Broken Hill in Northern Rhodesia to the Congo border. He has done for Congo copper what Lord Leverhulme has accomplished for palm fruit and Thomas F. Ryan for diamonds. Congo progress is almost entirely due to alien capital. ”
