This abolitionist pamphlet published by the British and Foreign Anti-Slavery Society focuses on Spanish slave trading to Cuba, and the cost to the British tax payer in suppressing it, estimated at one million pounds annually. Stopping the slave trade to Cuba is described as a priority for the Society: "there is no more immediately practical subject to which the attention of anti-slavery friends throughout the country can be directed" (1), and it is argued that open violation of the treaties signed should no longer be tolerated by Britain.
