for the provisions serving to the support of human life, produced by one acre of inclosed and cultivated land, are (to speak much within compass) ten times more than those which are yielded by an acre of land of an equal richness lying waste in common. And therefore he that incloses land, and has a greater plenty of the conveniencies of life from ten acres, than he could have from an hundred left to nature, may truly be said to give ninety acres to mankind: for his labour now supplies him with provisions out of ten acres, which were but the product of an hundred lying in common. I have here rated the improved land very low, in making its product but as ten to one, when it is much nearer an hundred to one: for I ask, whether in the wild woods and uncultivated waste of America, left to nature, without any improvement, tillage or husbandry, a thousand acres yield the needy and wretched inhabitants as many conveniencies of life, as ten acres of equally fertile land do in Devonshire, where they are well cultivated?
Gainera, ez zait iruditzen bere lan jardunaren bitartez lur eremu bat bereganatzen duen horrek gizateriaren bizigaiak txikiagotzen dituenik, handiagotu baizik. Lur eremu hesitu eta laboratuko akre batetik lortzen den mozkina, lugorrian dagoen kalitate bereko jabetza komuneko lur akre batetik ateratzen denaren hamar aldiz handiagoa da (estimazio txikienaren arabera).
