In 1749 the son of the architect, Dance, who built old Buckingham House and Guy's Hospital, was imprisoned in the Fleet for debt. He wrote and published a poem called "The Humors of the Fleet," which has an interest for comparison with what the prison became later. The book had a frontispiece showing the prison-yard, a newcomer treating the jailer and cook and others to drink; racket-players at their game; and in one corner of the yard a pump and a tree. When the Fleet was rebuilt after the riots, there were two exercise grounds within the walls. One, the smaller, was on the side toward Farringdon street, denominated and called "The Painted Ground," from the fact of its walls having once displayed the "semblances of various men-of-war in full sail, and other artistical effects, produced, in bygone days, by some imprisoned draughtsman in his leisure hours." On the other side of the prison was the larger yard where racket was played and games of skittles bowled beneath a shed. Here might be seen the characterless "characters" of the place, in which every prison is sure to abound. Smokers and other idlers loitered about the steps leading to the racket ground, draining their pots as they watched the game. Here Mr. Smangle "made a light and wholesome breakfast on a couple of cigars" Mr. Pickwick had paid for, and here Mr. Weller, with a pint of beer and the day before yesterday's paper, divided his time between dipping into the news and the noggin, the skittle game and the affections of a young lady who was peeling potatoes at one of the jail windows, on that memorable morning when Mr. Stiggins called upon him and sampled the port wine in the coffee-room snuggery. Here you might hear the roar of the great babel without; and from the same point see one or two of its churches aspiring above the 'chevaux-de-frise' of the prison walls. There was a torrent-like fury about the busy hum of the town in contrast with the stagnant life within the brick walls; and, as if to keep up the mockery, they verged upon the yard of the Belle Sauvage Inn, where travelers constantly came and went on their journeys, free, if they chose, to roam around the world. In chapter xvii of volume II, Dickens sketches a vivid picture of the daily scene in the jail-yard.
