In the accompanying map Nigeria is divided into four great Provinces. I. The Northern or Sudan Province, comprising the regions where a Mohammedan civilization has existed for many centuries, and where the majority of the people, except in Kontagora, are Muslims. The ruling families in Kontagora are, however, so closely related with those of Sokoto that it would probably be found expedient to incorporate the former into the same Province, which would, therefore, consist of Sokoto, Kano, Bornu, the Zaria Emirate and Kontagora. Its headquarters would be Kano. II. The Central Province, comprising the pagan section of the present Zaria province, _i.e._ Zaria outside the limits of the Emirate proper, and the Nassarawa, Bauchi, Niger, Yola, and Muri (north of the Benue) provinces. It is not quite easy to forecast where the centre of gravity of the Central Province will ultimately fall, but if, as is possible, the Bauchi highlands become in time a second Simla for the Central Executive, the headquarters of the Central Province would presumably be fixed at Zungeru, the present capital of the Northern Protectorate. III. The Western Province, comprising all that is now incorporated in the existing western province of Southern Nigeria, plus—to the north—Kabba, Ilorin and Borgu, while the right bank of the Forcados and Niger would form the eastern boundary, the boundaries of the Province following natural lines. Its headquarters would be Oshogbo, or its immediate neighbourhood. IV. The Eastern Province, comprising what is now the eastern province of South Nigeria, but with its western frontier coterminous with the left bank of the Niger and Forcados and its northern frontiers pushed up to the south bank of the Benue, embracing Bassa and part of Muri, Yola, however, being left, for political reasons, in the Central Province, as noted above. Its headquarters would be Old Calabar, the starting-point of the future eastern railway (see map).
