This is the Sum of what I think most likely to stop the Progress of the _Disease_ in any Place, where it shall have got Admittance. If some few of these _Rules_ refer more particularly to the City of _London_, with small Alteration they may be applied to any other _Place_. It now remains therefore only to lay down some Directions to hinder the _Distemper's_ spreading from _Town_ to _Town_. The best Method for which, where it can be done, is to cast up a _Line_ about the _Town infected_, at a convenient Distance; and by placing a _Guard_, to hinder People's passing from it without due Regulation, to other Towns: But not absolutely to forbid any to withdraw themselves, as they have now done in _France_, according to the usual Practice abroad; which is an unnecessary Severity, not to call it a Cruelty. I think it will be enough, if all, who desire to pass the _Line_, be permitted to do it, upon Condition they first perform _Quarantine_ for about 20 Days in _Tents_, or other more convenient _Habitations_. But the greatest Care must be taken, that none pass without conforming themselves to this Order, both by keeping diligent _Watch_, and by _punishing_ with the utmost Severity, any that shall either have done so, or attempt it. And the better to discover _such_, it will be requisite to oblige all, who travel in any Part of the Country, under the same Penalties, to carry with them _Certificates_ either of their coming from Places not _Infected_, or of their passing the _Line_ by permission.
