History of Nigeria (1969) was first published in 1929 and completely revised by its author, and gives the history of Nigeria from before its first encounters with the British, through colonial rule, and up to independence in 1960. It describes the peoples of Nigeria and the British conquest and colonial administration, and is full of detailed and valuable information relating to trade and industry, transport, housing, land tenure, education, religion and tribal customs. Appendices feature royal genealogies and the texts of treaties.

History of the British West Indies (1954) examines the history of the islands of the Caribbean from their first discovery, through the periods of colonisation and slavery, and up to the beginnings of their status as independent nations. The actions of other nations are studied, as well as the British, as the various colonial powers vied for possession of these valuable possessions. Terrible cruelty was inflicted by colonial masters to the indigenous inhabitants, the slaves and indentured labour, and the worst of these are recorded in separate appendices.

Parliament as an Export (1966) deals with the adoption of overseas countries and particularly the Commonwealth countries of the British Parliamentary system. These countries examined are the original British colonies, the Dominions, the Indian sub-continent and the newer colonial territories.
