The Central Provinces are divided into two parts by the Satpura range of hills (q.v.), which runs south of the Nerbudda river from east to west; so that, speaking generally, it consists of districts north of the Satpuras, districts on the Satpura Provinces.
North of the Satpuras is,the rich valley of the Nerbudda, which may be said to begin towards the north of the Jubbulpore district and to extend westward through the district of Narsinghpur as far as the western limit of Hoshangabad, a distance of nearly 300 m.
In breadth it is about 30 m., extending between the Satpuras and the southern scarp of the Vindhyas.
South of the Satpuras lies the great plain of Chhattisgarh at a mean elevation above the sea of moo ft.; it has an area of 23,000 sq.
To the south of the Satpuras and extending along its base from west to east lie successively the Berar, Nagpur and Chhattisgarh plains.
It receives the drainage of the northern slopes of the Satpuras, but not that of the Vindhyan tableland, the streams from which flow into the Ganges and Jumna.
The high tableland of the Balaghat lies for the most part upon the great basaltic formation which stretches across the Satpuras as far east as Jubbulpore.
The rains, however, are prolonged some three or four weeks later than in tracts to the north of the Satpuras, since they are also brought by the easterly winds which blow from the Bay of Bengal in October and the early part of November, when the recurved southerly wind ceases to blow up the Gangetic valley, and sets towards the south-east coast.
