He is best known for his work in the
British Empire's legal service as
Attorney General of Zanzibar in the 1930s, and then as
Attorney General of Fiji from 1945 to 1949. His work,
The Dual Jurisdiction in Zanzibar, described the
Protectorate's system of indirect
British rule, whereby
sovereignty technically remained with the
Sultan of Zanzibar but with virtually all effective power in the hands of British-appointed officials. He was also a
botanist who collected plants from what is now
Tanzania and
Fiji. He put together an important collection of plants from
Zanzibar and the eastern provinces of
Tanganyika. ==Personal life==
