Blood initially wanted to study for the Episcopalian ministry but changed his mind and in 1920 he entered the
Ceylon Civil Service. He served in
Ceylon between 1920 and 1930 before being appointed as Colonial Secretary of Grenada in 1930, and then Colonial Secretary of Sierra Leone in 1934. In 1942, Blood became
Governor of the Gambia, the first of three governorships. His administration was responsible for drawing up plans of how the
Colonial Development and Welfare Act funds were to be spent. During his time, the modernization of the
Bathurst water system, the establishment of a sewage system, paved streets, and improvements to the port all took place. Blood also established the Bathurst Town Council in 1946, introducing a new constitution for direct elections later that year. He then served as
Governor of Barbados from 1947 to 1949, and
Governor of Mauritius from 1949 to 1954. His experience equipped him with an understanding of the problems British territories faced when seeking self-government. His expertise was called on as a constitutional commissioner to help frame governments in
British Honduras,
Zanzibar, and
Malta. He also wrote a number of articles and reviews in the academic journal
African Affairs. In 1944, he was knighted, and in the same year he received an honorary doctor of laws from Glasgow University. == Later life ==
