it off. He met Esther Milnes (1753–1792), an heiress from Chesterfield, and they were married on 7 August 1778. The couple subsequently moved to a small estate at Stapleford Abbotts, near Abridge in Essex. They lived a very ascetic lifestyle and Esther was not allowed to contact her family. In 1780, the couple moved to Anningsley in Surrey, when Day bought a new estate there. It was a philanthropic project for both husband and wife and they laboured to improve the conditions of the working classes around them. Publications and political works In 1773, Day published his first work—The Dying Negro—a poem he had written with John Bicknell. It tells the story of a runaway slave, and sold well. The contradiction between the claim that "all men are created equal" and the existence of American slavery attracted comment from some quarters when the United States Declaration of Independence was first published; Congress, having made a few changes in wording, deleted nearly a fourth of the draft before publication, most notably removing a passage critical of the slave trade, as there were members of Congress who owned black slaves. Day was among those who noted the discrepancy, writing in 1776: "If there be an object truly ridiculous in nature, it is an American patriot, signing resolutions of independency with the one hand, and with the other brandishing a whip over his affrighted slaves." Day decided to study the law and in 1776 was admitted to Lincoln's Inn; he rarely practised. Day argued for the rights of the American colonists in his poem "The Devoted Legions" (1776) and in 1780 he argued in Parliament for an early peace with the revolutionaries as well as parliamentary reform. His speeches were also published as pamphlets. It was as a writer for children that Day made his reputation. The History of Little Jack (1787) was extremely popular, but it could not match the sales of The History of Sandford and Merton (1783, 1786, 1789) which was a bestseller for over a hundred years. Embracing Rousseau's dictates in many ways, it narrates the story of the rich, noble but spoiled Tommy Merton and his poor but virtuous friend Harry Sandford. Through trials and stories, Harry and the boys' tutor teach Tommy the importance of labor and the evils of the idle rich. Death Day was thrown from his horse while trying to break it using kindness
