and accidental differences: As for example; It were good to know the Geometrical Content, Figure, and Situation of all the Lands of a Kingdom, especially according to its most natural, permanent, and conspicuous Bounds. It were good to know how much Hay an Acre of every sort of Meadow will bear; how many Cattel the same weight of each sort of Hay will feed and fatten; what quantity of Grain and other Commodities the same Acre will bear in one, three, or seven years, communibus Annis; unto what use each soil is most proper. All which particulars I call the intrinsick value: for there is also another value meerly accidental, or extrinsick, consisting of the Causes why a parcel of Land, |99| lying near a good Market, may be worth double to another parcel, though but of the same intrinsick goodness; which answers the Queries, why Lands in the North of England are worth but sixteen years purchase, and those of the West above eight and twenty. It is no less necessary to know how many People there be of each Sex, State, Age, Religion, Trade, Rank, or Degree, &c. by the knowledge whereof, Trade and Government may be made more certain and Regular; for, if men knew the People, as aforesaid, they might know the consumption they would make, so as Trade might not be hoped for where it is impossible. As for instance, I have heard much complaint, that Trade is not set in some of the South-western and North-western Parts of Ireland, there being so many excellent Harbours for that purpose; whereas in several of those places I have also heard, that there are few other Inhabitants, but such as live ex sponte creatis, and are unfit Subjects of Trade, as neither employing others, nor working themselves.
Moreover, if all these things were clearly and truly known (which I have but ghessed at) it would appear, how small a part of the People work upon necessary Labours and |100| Callings, viz. how many Women and Children do just nothing, only learning to spend what others get; how many are meer Voluptuaries, and as it were meer Gamesters by Trade; how many live by puzling poor people with unintelligible Notions in Divinity and Philosophy; how many by perswading credulous, delicate, and ligitious Persons, that their Bodies or Estates
