It is here to be noted, that in this table we have assigned a different number of years for the time of doubling the people in the several ages of the world, and might have done the same for the several countries of the world, and therefore the said several periods assigned to the whole world in the lump may well enough consist with the 360 years especially assigned to England, between this day and the Norman Conquest; and the said 360 years may well enough serve for a supposition between this time and that of the world’s being fully peopled; nor do we lay any stress upon one or the other in this disquisition concerning the growth of the city of London.

We have spoken of the growth of London, with the measures and periods thereof; we come next to the causes and consequences of the same.

The causes of its growth from 1642 to 1682 may be said to have been as follows, viz.:—From 1642 to 1650, that men came out of the country to London, to shelter themselves from the outrages of the Civil Wars during that time; from 1650 to 1660, the royal party came to London for their more private and inexpensive living; from 1660 to 1670, the king’s friends and party came to receive his favours after his happy restoration; from 1670 to 1680, the frequency of plots and parliaments might bring extraordinary numbers to the city; but what reasons to assign for the like increase from 1604 to 1642 I know not, unless I should pick out some remarkable accident happening in each part of the said period, and make that to be the cause of this increase (as vulgar people make the cause of every man’s sickness to be what he did last eat), wherefore, rather than so to say quidlibet de quolibet, I had rather quit even what I have above said to be the cause of London’s increase from 1642 to 1682, and put the whole upon some natural and spontaneous benefits and advantages that men find by living in great more than in small societies, and shall therefore seek for the antecedent causes of this growth in the consequences of the like, considered in greater characters and proportions.

Now, whereas in arithmetic, out of two false positions the truth is extracted, so I hope out of two extravagant contrary suppositions to draw forth some solid and consistent conclusion, viz.:—

The first of the said two suppositions is, that the city of London is seven times bigger than now, and that the inhabitants of it are 4,690,000 people, and that in all the other cities, ports, towns, and villages, there are but 2,710,000 more.

The other supposition is, that the city of London is but a seventh part of its present bigness, and that the inhabitants of it are but 96,000, and that the rest of the inhabitants (being 7,304,000) do cohabit thus: 104,000 of them in small cities and towns, and that the rest, being 7,200,000, do inhabit in houses not contiguous to one another, viz., in 1,200,000 houses, having about twenty-four acres of ground belonging to each of them, accounting about 28,000,000 of acres to be in the whole territory of England, Wales, and the adjacent islands, which any man that pleases may examine upon a good map.

Now, the question is, in which of these two imaginary states would be the most convenient, commodious, and comfortable livings?

But this general question divides itself into the several questions, relating to the following particulars, viz.:—

1. For the defence of the kingdom against foreign powers.

2. For preventing the intestine commotions of parties and factions.

3. For peace and uniformity in religion.

4. For the administration of justice.

5. For the proportionably taxing of the people, and easy levying the same.

6. For gain by foreign commerce.

7. For husbandry, manufacture, and for arts of delight and ornament.

8. For lessening the fatigue of carriages and travelling.

9. For preventing beggars and thieves.

10. For the advancement and propagation of useful learning.

11. For increasing the people by generation.

12. For preventing the mischiefs of plagues and contagious. And withal, which of the said two states is most practicable and natural, for in these and the like particulars do lie the tests and touchstones of all proposals that can be made for the public good.

First, as to practicable, we say, that although our said extravagant proposals are both in nature possible, yet it is not obvious to every man to conceive how London, now seven times bigger than in the beginning of Queen Elizabeth’s reign, should be seven times bigger than now it is, and forty-nine times bigger than A.D. 1560. To which I say, 1. That the present city of London stands upon less than 2,500 acres of ground, wherefore a city seven times as large may stand upon 10,500 acres, which is about equivalent to a circle of four miles and a half in diameter, and less than fifteen miles in circumference. 2. That a circle of ground of thirty-five miles semidiameter will bear corn, garden-stuff, fruits, hay, and timber, for the 4,690,000 inhabitants of the said city and circle, so as nothing of that kind need be brought from above thirty-five miles distance from the said city; for the number of acres within the said circle, reckoning two acres sufficient to furnish bread and drink-corn for every head, and two acres will furnish hay for every necessary horse; and that the trees which may grow in the hedgerows of the fields within the said circle may furnish timber for 600,000 houses. 3. That all live cattle and great animals can bring themselves to the said city; and that fish can be brought from the Land’s End and Berwick as easily as now. 4. Of coals there is no doubt: and for water, 20s. per family (or £600,000 per annum in the whole) will serve this city, especially with the help of the New River. But if by practicable be understood that the present state may be suddenly changed into either of the two above-mentioned proposals, I think it is not practicable. Wherefore the true question is, unto or towards which of the said two extravagant states it is best to bend the present state by degrees, viz., Whether it be best to lessen or enlarge the present city? In order whereunto, we inquire (as to the first question) which state is most defensible against foreign powers, saying, that if the above-mentioned housing, and a border of ground, of three-quarters of a mile broad, were encompassed with a wall and ditch of twenty miles about (as strong as any in Europe, which would cost but a million, or about a penny in the shilling of the house-rent for one year) what foreign prince could bring an army from beyond seas, able to beat—1. Our sea-forces, and next with horse harassed at sea, to resist all the fresh horse that England could make, and then conquer above a million of men, well united, disciplined, and guarded within such a wall, distant everywhere three-quarters of a mile from the housing, to elude the granadoes and great shot of the enemy? 2. As to intestine parties and factions, I suppose that 4,690,000 people united within this great city could easily govern half the said number scattered without it, and that a few men in arms within the said city and wall could also easily govern the rest unarmed, or armed in such a manner as the Sovereign shall think fit. 3. As to uniformity in religion, I conceive, that if St. Martin’s parish (may as it doth) consist of about 40,000 souls, that this great city also may as well be made but as one parish, with seven times 130 chapels, in which might not only be an uniformity of common prayer, but in preaching also; for that a thousand copies of one judiciously and authentically composed sermon might be every week read in each of the said chapels without any subsequent repetition of the same, as in the case of homilies. Whereas in England (wherein are near 10,000 parishes, in each of which upon Sundays, holy days, and other extraordinary occasions there should be about 100 sermons annum, making about a million of sermons per annum in the whole) it were a miracle, if a million of sermons composed by so many men, and of so many minds and methods, should produce uniformity upon the discomposed understandings of about 8,000,000 of hearers.

4. As to the administration of justice. If in this great city shall dwell the owners of all the lands, and other valuable things in England; if within it shall be all the traders, and all the courts, offices, records, juries, and witnesses; then it follows that justice may be done with speed and ease.

5. As to the equality and easy levying of taxes. It is too certain that London hath at some time paid near half the excise of England, and that the people pay thrice as much for the hearths in London as those in the country, in proportion to the people of each, and that the charge of collecting these duties have been about a sixth part of the duty itself. Now in this great city the excise alone according to the present laws would not only be double to the whole kingdom, but also more equal. And the duty of hearths of the said city would exceed the present proceed of the whole kingdom. And as for the customs we mention them not at present.

6. Whether more would be gained by foreign commerce? The gain which England makes by lead, coals, the freight of shipping, &c., may be the same, for aught I see, in both cases. But the gain which is made by manufactures will be greater as the manufacture itself is greater and better. For in so vast a city manufactures will beget one another, and each manufacture will be divided into as many parts as possible, whereby the work of each artisan will be simple and easy. As, for example, in the making of a watch, if one man shall make the wheels, another the spring, another shall engrave the dial-plate, and another shall make the cases, then the watch will be better and cheaper than if the whole work be put upon any one man. And we also see that in towns, and in the streets of a great town, where all the inhabitants are almost of one trade, the commodity peculiar to those places is made better and cheaper than elsewhere. Moreover, when all sorts of manufactures are made in one place, there every ship that goeth forth can suddenly have its loading of so many several particulars and species as the port whereunto she is bound can take off. Again, when the several manufactures are made in one place, and shipped off in another, the carriage, postage, and travelling charges, will enhance the price of such manufacture, and lessen the gain upon foreign commerce. And lastly, when the imported goods are spent in the port itself, where they are landed, the carriage of the same into other places will create no further charge upon such commodity; all which particulars tend to the greater gain by foreign commerce.

7. As for arts of delight and ornament. They are best promoted by the greatest number of emulators. And it is more likely that one ingenious curious man may rather be found out amongst 4,000,000 than 400 persons. But as for husbandry, viz., tillage and pasturage, I see no reason, but the second state (when each family is charged with the culture of about twenty-four acres) will best promote the same.

8. As for lessening the fatigue of carriage and travelling.

The thing speaks for itself, for if all the men of business, and all artisans, do live within five miles of each other, and if those who live without the great city do spend only such commodities as grow where they live, then the charge of carriage and travelling could be little.

9. As to the preventing of beggars and thieves.
