Major Barker spent nearly twenty years of his life in the Game Preservation Department of the Sudan. During the last fifteen years he worked single-handed with only a clerk to help him. The Sudan is nearly a million square miles in area, and in Major Barker's days the methods of communication were road, rail, and river only. Yet he managed during his service to create two national parks and ten game reserves, to bring the game laws up to date in such a form that they could be easily enforced, and to leave game preservation throughout most of the country in an excellent state.
