Typed manuscript entitled, "Chinese Secret Societies in Malaya. Sections K. L. + M. The Chinese factor in the Policy of Intervention" concerning the time period 1872-1876. It is also labelled as "File 5" and "Duplicate". It appears to be an early draft or research material for part of Blythe's book The Impact of Chinese Secret Societies in Malaya published in 1969. The material seems to be in more depth than the corresponding material covered within the publication. With the file is a note which reads, "It is possible that Prof. Cowan at S.O.A.S., London, would like to have this File 5, as it deals with the subject of his book on Intervention".

These Papers of William (Bill) Roff relate mainly to his research interests in the Hajj pilgrimage particularly among pilgrims from Southeast Asia. The material consists of research notes, papers of Roff and others, and official documents.
