From it issues the Kebbi (Mao Kebi) a tributary of the Benue, and through it flows a tributary of the Logone, the chief affluent of the Shari.
In the vicinity of the rivers Benue, Faro and Kebbi, the people, who are good agriculturists, raise cereals and other crops, while on the plateaus stock-raising forms the chief pursuit of the inhabitants.
Tributaries of the Niger traverse the western portion of the country, the most noteworthy being the Gulbin Kebbi or Sokoto river and the Kaduna, which flows through a valley not more than 500 ft.
With the Chad system it is connected by the Kebbi or Mayo Kebbi, a right-hand tributary whose confluence is in about 91° N., 131° E.
The Kebbi, fed by many torrents rising in the eastern versant of the Mandara Hills, issues from the S.W.
The Kebbi flows west, and soon after leaving Tuburi passes through a rocky barrier marked by a series of rapids and a fall at Lata of 165 ft.
Below these obstructions the Kebbi to its junction with the Benue has a depth of not less than 6 ft.
Below the Kebbi confluence the Benue, now a considerable river, turns from a northerly to a westerly direction and is navigable all the year round by boats drawing not more than 21 ft.
By the "Pleiad" expedition, and in 1889 to 131° E., and the Kebbi to Bifara by Major (afterwards Sir Claude) Macdonald, further progress towards the Tuburi marsh being prevented by the shallowness of the water.
He ascended the Kebbi and discovered the Lata Fall, continuing up the river to its point of issue from Tuburi.
Running through it in a south-westerly direction is the Gublin Kebbi or Sokoto river, which joins the Niger in 112° N.
Gobir and Kebbi remained Unconquered, as did the pagan hill tribes.
It includes the ancient kingdoms of Zamfara on the east and Argunga or Kebbi on the west.
