This was in 1755, but in 1756 he married, and made his first appearance in the literary world by the publication of a book. About these years from 1750 to 1759 little is known. He published two works, one a treatise on the 'Origin of our Ideas of the Sublime and Beautiful,' and the other a 'Vindication of Natural Society,' a satire on Bolingbroke. Stray allusions and anecdotes about other men in the diaries and correspondence of the time show that he frequented the literary coffee-houses, and was gradually making an impression on the authors and wits whom he met there. Besides the two books we have mentioned, he produced some smaller things, such as an 'Essay on the Drama,' and part of an 'Abridgment of the History of England.' But although these helped to secure him admission to the literary set, they did not raise him out of the rank of obscure literary adventurers, who from the Revolution of 1688, and especially after the union with Scotland, began to swarm to London from all parts of the three kingdoms. The first recognition of him as a serious writer was his employment by Dodsley the bookseller, at a salary of $100 a year, to edit the Annual Register, which Dodsley founded in 1769. Considered as a biographical episode, this may fairly be treated as a business man's certificate that Burke was industrious and accurate. As his income from his father was withdrawn or reduced in 1755, there remain four years during which his way of supporting himself is unknown. His published works were certainly not "pot-boilers." He was probably to some extent dependent on his wife's father, Dr. Nugent, an Irish physician who when Burke made his acquaintance lived in Bath, but after his daughter's marriage settled in London, and seems to have frequented and have been acceptable in the same coffee-houses as Burke, and for the same reasons. But Burke was not a man to remain long dependent on any one. These nine years were evidently not spent fruitlessly. They had made him known and brought him to the threshold of public life.
