And were this very fundamental only duly considered by the people on any future occasion of this or the like nature, I am persuaded it would put them upon quite different measures for managing the people from those that they took in 1665, or than any that have been taken abroad that I have heard of.  In a word, they would consider of separating the people into smaller bodies, and removing them in time farther from one another—­and not let such a contagion as this, which is indeed chiefly dangerous to collected bodies of people, find a million of people in a body together, as was very near the case before, and would certainly be the case if it should ever appear again.

The plague, like a great fire, if a few houses only are contiguous where it happens, can only burn a few houses; or if it begins in a single, or, as we call it, a lone house, can only burn that lone house where it begins.  But if it begins in a close-built town or city and gets a head, there its fury increases:  it rages over the whole place, and consumes all it can reach.

I could propose many schemes on the foot of which the government of this city, if ever they should be under the apprehensions of such another enemy (God forbid they should), might ease themselves of the greatest part of the dangerous people that belong to them; I mean such as the begging, starving, labouring poor, and among them chiefly those who, in case of a siege, are called the useless mouths; who being then prudently and to their own advantage disposed of, and the wealthy inhabitants disposing of themselves and of their servants and children, the city and its adjacent parts would be so effectually evacuated that there would not be above a tenth part of its people left together for the disease to take hold upon.  But suppose them to be a fifth part, and that two hundred and fifty thousand people were left:  and if it did seize upon them, they would, by their living so much at large, be much better prepared to defend themselves against the infection, and be less liable to the effects of it than if the same number of people lived dose together in one smaller city such as Dublin or Amsterdam or the like.

It is true hundreds, yea, thousands of families fled away at this last plague, but then of them, many fled too late, and not only died in their flight, but carried the distemper with them into the countries where they went and infected those whom they went among for safety; which confounded the thing, and made that be a propagation of the distemper which was the best means to prevent it; and this too is an evidence of it, and brings me back to what I only hinted at before, but must speak more fully to here, namely, that men went about apparently well many days after they had the taint of the disease in their vitals, and after their spirits were so seized as that they could never escape it, and that all the while they did so they were dangerous to others; I say, this proves that so it was; for such people infected the very towns they went through, as well as the families they went among; and it was by that means that almost all the great towns in England had the distemper among them, more or less, and always they would tell you such a Londoner or such a Londoner brought it down.
