endorsed the development of rubber plantations, a concept familiar to him from his time in Malaya, and arranged for land to be leased for this purpose. This was the foundation of a highly successful industry. He also thought there could be great potential in the tin fields near Bauchi, and thought that if proven a branch line to the tin fields would be justified. Egerton came into conflict with the administration of Northern Nigeria on a number of issues. There was debate over whether Ilorin should be incorporated into Southern Nigeria since the people were Yoruba, or remain in Northern Nigeria since the ruler was Muslim and for some time Ilorin had been subject to the Uthmaniyya Caliphate. There was argument about the administration of duties on goods landed on the coast and carried into Northern Nigeria. And there was dispute over whether railway lines from the north should terminate at Lagos or should take alternative routes to the Niger River and the coast. Egerton had reason on his side in objecting to the proposed line terminating at Baro on the Niger, since navigation southward to the coast was restricted to the high water season, and even then was uncertain. Egerton's administration imposed policies that tended towards segregation of Europeans and Africans. These included excluding Africans from the West African Medical Service and saying that no European should take orders from an African, which had the effect of ruling out African doctors from serving with the army. Egerton himself did not always approve of these policies, and they were not strictly upheld. The legal relationship between the Lagos government and the Yoruba states of the Lagos Colony was not clear, and it was not until 1908 that Egerton persuaded the Obas to accept the establishment of the Supreme Court in the main towns.

Lugard returned to Nigeria as Governor of the two protectorates. His main mission was to complete the amalgamation into one colony. Although controversial in Lagos, where it was opposed by a large section of the political class and the media, the amalgamation did not arouse
