This was the last plague of Chester, but for a small outbreak in 1654. The next vital statistics that we get for the city are more than a century after, in 1774[64]. The population of 14,713 was then divided into two almost distinct parts, separated by the wall. The old city was being rebuilt, all but some ancient blocks of buildings held in the dead hand of the cathedral chapter; it was becoming a model 18th century place of residence for a wealthy and refined class, who were remarkably healthy and not very prolific, the parishes wholly within the walls having 3502 inhabitants. The poorer class had gone to live mostly outside the walls in new and mean suburbs, the three parishes at the Gates and extending now far beyond the walls, together with the original extramural parish of St John’s, having a population of 11,211. There was no town in Britain where the separation of the rich from the poor was more complete; there was hardly another town of the size where the health of the rich was better; and although the health of the populace was not so bad as in the manufacturing towns of Lancashire and Cumberland, close at hand, yet it is hardly possible to find so great a contrast as that between the clean and wholesome residential quarter within the walls and the mean fever-stricken suburbs as described by Haygarth in 1774: “The inhabitants of the suburbs,” he says, “are generally of the lowest rank; they want most of the conveniences and comforts of life; their houses are small, close, crowded and dirty; their diet affords very bad nourishment, and their cloaths are seldom changed or washed.... These miserable wretches, even when they go abroad, carry a poisonous atmosphere round their bodies that is distinguished by a noisome and offensive smell, which is peculiarly disgustful even to the healthy and vigorous, exciting sickness and a sense of general debility. It cannot therefore be wondered that diseases should be produced where such poison is inspired with every breath.” The case of Chester shows by broader contrasts than anywhere else the change from the public health of plague-times to that of more modern times. But it can hardly be said to show the populace better off than before; it shows them changed into a proletariat, and separated from the richer classes by walls several feet thick. Such, at least, was the result after four generations of immunity from plague, a result which indicates, as I have said, that we may easily make too much of the improved well-being of the poorer classes as a cause of the cessation of plague.
