13. Suppose a man could with his own hands plant a certain scope of Land with Corn, that is, could Digg, or Plough, Harrow, Weed, Reap, Carry home, Thresh, and Winnow so much as the Husbandry of this Land requires; and had withal Seed wherewith to sowe the same. I say, that when this man hath subducted his seed out of the proceed of his Harvest, and also, what himself hath both eaten and given to others in exchange for Clothes, and other Natural necessaries; that the remainder of Corn, is the natural and true Rent of the Land for that year; and the medium of seven years, or rather of so many years as makes up the Cycle, within which Dearths and Plenties make their revolution, doth give the ordinary Rent of the Land in Corn.

14. But a further, though collaterall question may be, how much English money this Corn or Rent is worth? I answer, so much as the money, which another single man can save, within the same time, over and above his expence, if he imployed himself wholly to produce and make it; viz. Let another man go travel into a Countrey where is Silver, there Dig it, Refine it, bring it to the same place where the other man planted his Corn; Coyne it, &c. the same person, all the while of his working for Silver, gathering also food for his necessary livelihood, and procuring himself covering, &c. I say, the Silver of the one, must be esteemed of equal value with the Corn of the other; the one being perhaps twenty Ounces, and the other twenty Bushels. From whence it follows, that the price of a Bushel of this Corn to be an Ounce of Silver.

15. And forasmuch as possibly there may be more Art and Hazzard in working about the Silver, then about the Corn, yet all comes to the same pass; for let a hundred men work ten years upon Corn, and the same number of men, the same time, upon Silver; I say, that the neat proceed of the Silver is the price of the whole neat proceed of the Corn, and like parts of the one, the price of like parts of the other. Although not so many of those who wrought in Silver, learned the Art of refining and coining, or out-lived the dangers and diseases of working in the Mines. And this also is the way of pitching the true proportion, between the values of Gold and Silver, which many times is set but by popular errour, sometimes more, sometimes less, diffused in the world; which errour (by the way) is the cause of our having been pestred with too much Gold heretofore, and wanting it now.

16. This, I say, to be the foundation of equallizing and ballancing of values; yet in the superstructures and practices hereupon, I confess there is much variety, and intricacy; of which hereafter.

17. The world measures things by Gold and Silver, but principally the latter; for there may not be two measures, and consequently the better of many must be the onely of all; that is, by fine silver of a certain weight; but now if it be hard to measure the weight and fineness of silver, as by the different reports of the ablest Saymasters I have known it to be; and if silver granted to be of the same fineness and weight, rise and fall in its price, and be more worth at one place then another, not onely for being farther from the Mines, but for other accidents, and may be more worth at present, then a moneth or other small time hence; and if it differ in its proportion unto the several things valued by it, in several ages upon the increase and diminution thereof, we shall endeavour to examine some other natural Standards and Measures, without derogating from the excellent use of these.

18. Our Silver and Gold we call by severall names, as in England by pounds, shillings, and pence, all which may be called and understood by either of the three. But that which I would say upon this matter is, that all things ought to be valued by two natural Denominations, which is Land and Labour; that is, we ought to say, a Ship or garment is worth such a measure of Land, with such another measure of Labour; forasmuch as both Ships and Garments were the creatures of Lands and mens Labours thereupon: This being true, we should be glad to finde out a natural Par between Land and Labour, so as we might express the value by either of them alone as well or better then by both, and reduce one into the other as easily and certainly as we reduce pence into pounds. Wherefore we would be glad to finde the natural values of the Fee simple of Land, though but no better then we have done that of the usus fructus abovementioned, which we attempt as followeth.

19. Having found the Rent or value of the usus fructus per annum, the question is, how many years purchase (as we usually say) is the Fee simple naturally worth? If we say an infinite number, then an Acre of Land would be equal in value to a thousand Acres of the same Land; which is absurd, an infinity of unities being equal to an infinity of thousands. Wherefore we must pitch upon some limited number, and that I apprehend to be the number of years, which I conceive one man of fifty years old, another of twenty eight, and another of seven years old, all being alive together may be thought to live; that is to say, of a Grandfather, Father, and Childe; few men having reason to take care of more remote Posterity: for if a man be a great Grandfather, he himself is so much the nearer his end, so as there are but three in a continual line of descent usually co-existing together; and as some are Grandfathers at forty years, yet as many are not till above sixty, and sic de cæteris.

20. Wherefore I pitch the number of years purchase, that any Land is naturally worth, to be the ordinary extent of three such persons their lives. Now in England we esteem three lives equal to one and twenty years, and consequently the value of Land, to be about the same number of years purchase. Possibly if they thought themselves mistaken in the one, (as the observator on the Bills of Mortality thinks they are) they would alter in the other, unless the confederation of the force of popular errour and dependance of things already concatenated, did hinder them.

21. This I esteem to be the number of years purchase where Titles are good, and where there is a moral certainty of enjoying the purchase. But in other Countreys Lands are worth nearer thirty years purchase, by reason of the better Titles, more people, and perhaps truer opinion of the value and duration of three lives.

22. And in some places, Lands are worth yet more years purchase by reason of some special honour, pleasures, priviledge or jurisdiction annexed unto them.
