Nigeria
Palmer spent the greater part of his long official service in Nigeria. His first posting was under Lugard, High Commissioner of the Northern Nigeria Protectorate, a position held by Lugard until 1906.
Palmer was appointed an assistant Resident in the Provinces of Nigeria in 1904. One of his early acts was to work towards the abolition of slavery that was still to be found in the Northern Provinces.
The appointment of Palmer as Resident in 1905 was a turning point in the history of British rule in Katsina. When he assumed office, the first task which Palmer accomplished was the re-organization of districts, in which nineteen new districts were created. Each of these was placed under the jurisdiction of a district head responsible to the Emir. The newly created districts were further divided into sub-districts, to allow for proper administration of the Emirate from the grassroots. Palmer installed Muhammadu Dikko as Emir of Katsina in 1906 largely due to his co-operation with the British administration. This was an early example of Palmer adopting the Lugard doctrine of Indirect Rule.
He was one of the most prominent of the band of political officers who guarded and guided the destinies of the Northern Nigerian Emirates and other political units, in the formative years round about 1910. By 1911, Palmer was Commissioner of Native Revenue in the north of the country. Their planning was accepted and confirmed by Lugard on his return.
In 1912, Lugard returned from Hong Kong to Nigeria as governor of the northern and southern protectorates. Lugard's 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 passion in the rest of the country. From 1914 to 1919, Lugard was Governor General of the now combined Colony of Nigeria.
Palmer acted as Resident of Kano Province between 1915 and 1916 and, in 1917, was promoted to Resident of Bornu Province.
He maintained the relationships which Lugard has established with the Sokoto Caliphate and the Sultan of Sokoto and, as Lugard, worked through Nigerian traditional rulers. Palmer was a staunch advocate of the principles of Indirect Rule or devolved colonial administration which had been devised by Lugard and his successors in the government of Northern Nigeria. It greatly enhanced the prestige and influence of the traditional Muslim emirs and contributed to the rapid spread of Islam during the colonial era. The position of the Emirs was supported by Palmer and he strongly opposed the work of Christian missionaries, for example in Borno, contrary to the views of the governor, Sir Hugh Clifford.
Owing to the Great War, the duties of senior administrative officers in Northern Nigeria were especially arduous at that time. By the end of 1917 some 6,600 troops had been dispatched to East Africa to take part in the operations against
Von Lettow's forces, and a further 1,800 were awaiting transport – a serious depletion of the garrison of the country. Palmer carefully considered the effects of the War on the Muslim provinces and was highly critical of the French Administration in their colony nearby.
Palmer studied the culture, languages and literature of Africa becoming an outstanding Hausa and Arabic scholar and an acknowledged authority on civilisation and literature of Hausa and Fulani.
Throughout the Northern Nigeria Protectorate there were then thousands of Muslim schools in which practically the entire time of the pupils was occupied in learning by heart and in writing portions of the Koran. Palmer, who was deeply interested in education, was anxious to improve on this system, and it was natural that he should turn his eyes towards the Gordon College at Khartoum, where important steps had been taken to improve Muslim education in the Sudan. He therefore made an arduous and adventurous journey in 1918 across Central Africa from Borno by way of Wadai and Darfur to the Sudan. This visit bore fruit when a training college for Muslim teachers was opened in 1922 at Katsina and attracted a promising number of candidates.
Palmer acted as Lieutenant Governor of Northern Nigeria from 1921, and was promoted to the substantive appointment in 1925 based in Kaduna.
He was a first class administrator described as "capax imperii", capable of (ruling the) Empire, with his understanding and study of languages and was referred to locally as "Judgey", being the highest judicial authority.
In 1919 steps had already been taken to develop the important cotton and ground-nut industries, and experimental work in tobacco cultivation had been started. Later, in 1926, work was begun on a scheme for utilising the waters of the Kaduna River for the supply of the town. Progress was also made in the construction of new European hospitals at Enugu, Jos and Kano in the province. Another important event was the journey undertaken by Palmer from Lagos to Lake Chad in March and April, this being the first occasion on which the entire distance had been traversed by motor transport.
During the 26 years spent by Palmer in various part of Northern Nigeria much of his leisure was occupied in attempts to find data for the completion of a true history of the more important units of ruling races, such as the Fulbe and Kanuri of Borno. In his journey across Africa in 1918, he was able to obtain first-hand information on matters connected with this subject. The results of these studies were embodied in a work entitled Sudanese Memoirs, the last volume of which was published in 1928. This work was supplemented by a book entitled The Bornu Sahara and Sudan and published in 1936.
In December 1929, Palmer argued strongly for decentralisation of funding to leave discretion of expenditure to be determined within the Northern Provinces. He was not able to persuade the Governor Sir Graeme Thomson nor the Secretary of State of the merits of allowing an overall budget to be allocated to the lieutenant governor. This issue remains a matter of debate to this day. It may be that this dispute prompted his move to The Gambia.
His departure from Nigeria was announced in February 1930.
