The greater part of Kordofan consists of undulating plains, riverless, barren, monotonous, with an average altitude of 1500 ft.
The Perche in the southwest and the Thimerais in the north-west are districts of hills and valleys, woods, lakes and streams. The region of the east and south is a level and uniform expanse, consisting for the most part of the riverless but fertile plain of Beauce, sometimes called the "granary of France."
