- John Clarkson (1764-1828) was an English abolitionist, agent for the Sierra Leone Company, and lieutenant in the British Royal Navy. The collection consists of Clarkson's manuscripts, written in journal form, of his involvement with the settlement of free African-American loyalists from Nova Scotia to Sierra Leone, Africa. The loyalists had been evacuated from New York when the British pulled out at the end of the Revolutionary War and initially settled in Nova Scotia. Volume 1, entitled "Clarkson's Mission to America," covers August 6, 1791-March 18, 1792 as Clarkson arranged for the transportation of the settlers; it provides a detailed account of his activities in Nova Scotia, persons he met there, and the problems fitting out the ships. Volume 2, entitled "Clarksons Mission to Africa," covers March 19, 1792-August 4, 1792. Clarkson's account of the founding and first months of Free Town, Sierra Leone gives numerous details of the difficulties met, relations with the native population, attitudes of the Nova Scotia settlers, and supplies.
