Another of the famous Southwark gaols was the King's Bench, but in justice to Mr. Micawber, it demands a chapter to itself. To return to the Marshalsea, it may be remarked that Dickens knew it by such early experience that he was qualified to write about it, even more exhaustively than he did in "Little Dorrit." While he was still a boy, in 1822, his father endured a period of compulsory retirement behind its lock, and the future chronicler of the jail lodged in a cheap garret near by, an episode of his life which he has introduced in "David Copperfield," in connection with the Micawbers and the King's Bench. Every morning, as soon as the gates were opened, the boy went to the Marshalsea, where his mother had joined his father, to breakfast. In the evening he would go to the jail from the blacking factory, where he was employed, to get his supper. The family got along quite gayly while the elder Dickens's affairs were in the courts. He had an income on which they lived and kept a servant, a workhouse girl, from whom the novelist is said to have drawn his character of The Marchioness in "Old Curiosity Shop." The girl and the boy had to leave the prison before ten, when the gate was locked for the night, and they became great friends. On holidays he would go to the seminary on Tenterden street, where his sister Fanny was at school, and fetch her to spend the day in the family circle, escorting her back in the evening. How freely he used his Marshalsea experiences in "David Copperfield," and transferred to Mr. Micawber the actualities of his own family life, may be appreciated from the passage, written by himself and quoted by Foster, relating to his first visit to his father in the jail:
