IN this brief communication I propose, without entering into particular details, to suggest the broad lines that I consider desirable for ecological investigations in South, Central and East Africa. The scheme is put forward entirely on my own responsibility, and not with the inspiration or authority of any government. Ecological research being a relatively novel line in scientific investigation, it behoves us to be particularly careful that we base that research upon practical foundations that are sound, and upon concepts that are broad and dynamic. The points that appeal to me as being of the first importance are based upon my own experience in e-cological research in South and East Africa. The territory under consideration comprises that constituted by the Union of South Africa, Swaziland, Basutoland, Bechuanaland, Southern and Northern Rhodesia, Nyassaland, Uganda, Tanganyika and Kenya.
