Richard Madden, who was appointed as a magistrate in Jamaica from February 1834, published an account of the period of 'apprenticeship' between slavery and freedom in the Caribbean colonies a year later in the form of a series of letters which include descriptions of the various British colonies, such as Barbados, Grenada and Jamaica. Madden was very critical of the idea of apprenticeship, and he would later become a correspondent and member of the British and Foreign Anti-Slavery Society.
