I think it will be but a very modest computation to say, that of the products of the earth useful to the life of man nine tenths are the effects of labour: nay, if we will rightly estimate things as they come to our use, and cast up the several expences about them, what in them is purely owing to nature, and what to labour, we shall find, that in most of them ninety-nine hundredths are wholly to be put on the account of labour.
Sect.41.There cannot be a clearer demonstration of any thing, than several nations of the Americans are of this, who are rich in land, and poor in all the comforts of life; whom nature having furnished as liberally as any other people, with the materials of plenty, i.e.a fruitful soil, apt to produce in abundance, what might serve for food, raiment, and delight; yet for want of improving it by labour, have not one hundredth part of the conveniencies we enjoy: and a king of a large and fruitful territory there, feeds, lodges, and is clad worse than a day-labourer in England.
Sect.42.To make this a little clearer, let us but trace some of the ordinary provisions of life, through their several progresses, before they come to our use, and see how much they receive of their value from human industry.

Bread, wine and cloth, are things of daily use, and great plenty; yet notwithstanding, acorns, water and leaves, or skins, must be our bread, drink and cloathing, did not labour furnish us with these more useful commodities: for whatever bread is more worth than acorns, wine than water, and cloth or silk, than leaves, skins or moss, that is wholly owing to labour and industry; the one of these being the food and raiment which unassisted nature furnishes us with; the other, provisions which our industry and pains prepare for us, which how much they exceed the other in value, when any one hath computed, he will then see how much labour makes the far greatest part of the value of things we enjoy in this world: and the ground which produces the materials, is scarce to be reckoned in, as any, or at most, but a very small part of it; so little, that even amongst us, land that is left wholly to nature, that hath no improvement of pasturage, tillage, or planting, is called, as indeed it is, waste; and we shall find the benefit of it amount to little more than nothing.
This shews how much numbers of men are to be preferred to largeness of dominions; and that the increase of lands, and the right employing of them, is the great art of government: and that prince, who shall be so wise and godlike, as by established laws of liberty to secure protection and encouragement to the honest industry of mankind, against the oppression of power and narrowness of party, will quickly be too hard for his neighbours: but this by the by.
To return to the argument in hand.
Sect.43.An acre of land, that bears here twenty bushels of wheat, and another in America, which, with the same husbandry, would do the like, are, without doubt, of the same natural intrinsic value: but yet the benefit mankind receives from the one in a year, is worth 5l.

and from the other possibly not worth a penny, if all the profit an Indian received from it were to be valued, and sold here; at least, I may truly say, not one thousandth.

It is labour then which puts the greatest part of value upon land, without which it would scarcely be worth any thing: it is to that we owe the greatest part of all its useful products; for all that the straw, bran, bread, of that acre of wheat, is more worth than the product of an acre of as good land, which lies waste, is all the effect of labour: for it is not barely the plough-man's pains, the reaper's and thresher's toil, and the baker's sweat, is to be counted into the bread we eat; the labour of those who broke the oxen, who digged and wrought the iron and stones, who felled and framed the timber employed about the plough, mill, oven, or any other utensils, which are a vast number, requisite to this corn, from its being feed to be sown to its being made bread, must all be charged on the account of labour, and received as an effect of that: nature and the earth furnished only the almost worthless materials, as in themselves.

It would be a strange catalogue of things, that industry provided and made use of, about every loaf of bread, before it came to our use, if we could trace them; iron, wood, leather, bark, timber, stone, bricks, coals, lime, cloth, dying drugs, pitch, tar, masts, ropes, and all the materials made use of in the ship, that brought any of the commodities made use of by any of the workmen, to any part of the work; all which it would be almost impossible, at least too long, to reckon up.
Sect.44.From all which it is evident, that though the things of nature are given in common, yet man, by being master of himself, and proprietor of his own person, and the actions or labour of it, had still in himself the great foundation of property; and that, which made up the great part of what he applied to the support or comfort of his being, when invention and arts had improved the conveniencies of life, was perfectly his own, and did not belong in common to others.
Sect.45.Thus labour, in the beginning, gave a right of property, wherever any one was pleased to employ it upon what was common, which remained a long while the far greater part, and is yet more than mankind makes use of.
