But the more elaborate interment of the dead was itself an index of the greater spending power of the community, and it may be said that it was the better condition of the people, and not this one particular thing in it, which put an end to the periodical recurrences of plague. In all but its earliest outbursts in the fourteenth, and perhaps the fifteenth century, plague had been peculiarly an infection of the poor, being known as “the poor’s plague.” Perhaps the chief reason why the richer classes usually escaped it was that they fled from the plague-tainted place, leaving the poorer classes unable to stir from their homes, exposed to the infectious air, and all the more exposed that their habitual employments and wages would cease, their sustenance become precarious, their condition lowered, and their manners reckless. Again, it was not unusual for the plague to break out in a season of famine or scarcity, during which the ordinary risks of the labouring class would be aggravated. Famines ceased (except in Ireland, where there had been comparatively little plague), and scarcities became less common. The sieges and occupations of the Civil Wars in the middle of the 17th century, which undoubtedly were the occasion of the last outbursts of plague in many of the towns, were a brief experience, followed by unbroken tranquillity. Whatever things were tending to the removal of plague in all its old seats had free course thereafter. On the other hand, one may make too much of the increase of well-being among the labouring class which coincided with the cessation of plague. As a check upon population plague worked in a very remarkable way. In London, as well as in towns like Newcastle and Chester, plague towards the end of its reign arose perhaps once in a generation and made a clean sweep of a fifth or a fourth part of the inhabitants, including hardly any of the well-to-do. It destroyed, of course, many bread-winners and many that were not absolutely sunk in poverty; but its broad effect was to cut off the margin of poverty as if by a periodical process of pruning. The Lord Mayor of London wrote to the Privy Council at the end of the great plague of 1625: “The great mortality, although it had taken many poor people away, yet had made more poverty by decay of tradesmen”--a decay of trade which they might reasonably expect to recover from before long. No such ruthless shears was ever applied at intervals to the growing fringe of poverty in after times. The poor were a more permanent residue, pressing more upon each other; but they did not press more upon the rich, except through the poor rate; on the contrary, the separation of classes became more marked.
