These general correspondence files form the "M" series of files from the Police Commissioner's Office. They consist mainly of reports by police officers and related correspondence.
They cover a wide range of activities involving or affecting the Queensland Police Force including the employment of black trackers, proceedings brought against medical officers and bogus doctors, strikes involving Queensland industries, professions and companies, notification of injuries and fatalities in aeroplane accidents, the discovery of human remains and visits to Queensland by royalty and other distinguished persons.
There are files relating to the first and second World Wars which include records of internment and registration of aliens and the American forces in Queensland, the confiscation and return of firearms, the activities of communists and Axis sympathisers, breaches of security regulations and case history files on enquiries carried out for the Department of Children's Services, V.D. suspects, prostitution and illegal immigrants and other aliens.
There are also files concerning work undertaken by police on behalf of other government departments, for example, the inspection of brands and stock, government relief, the escort of Aborigines, the insane, gold or payrolls and the collection of statistical data. These files have been given subject-based file titles.
Each file title has been allocated a file number with an 'M' suffix. Subsequent files on the same subject are numbered progressively eg. 153M, 153M 1.
