From the early years of the century the native authorities (and the Buganda Government) were responsible for the maintenance of certain services, with the Commissioners playing a more supervisory role in those areas. District Commissioners had from the earliest times submitted annual reports surveying district work during the previous year, but these were not published, nor were copies of them normally transmitted to the Colonial Office. The series of Provincial Commissioners' Reports on Native Administration included in this collection begins with the reports for 1935; these reports were based on those that the provincial commissioners had received from their district commissioners. The titles of the reports changed with the 1939-1946 publication, from 'Uganda Protectorate Reports' to 'Reports on the Kingdom of Buganda, Eastern Province and Western Provinces'. These reports focus upon the native administration in general and upon the police service in particular.
