food, by reason of the Freight, and hazard in carrying the same from Peru to Russia; and in Russia the price of Silver shall grow to be worth more days labour, if a Workman can by the esteem and request of Silver Utensils earn more than he can on other materials. Wherefore I valued an Irish Cabbin at the number of days food, which the Maker spent in building of it. |66|
By the same way we must make a Par and Equation between Art and Simple Labour; for if by such Simple Labour I could dig and prepare for Seed a hundred Acres in a thousand days; suppose then, I spend a hundred days in studying a more compendious way, and in contriving Tools for the same purpose; but in all that hundred days dig nothing, but in the remaining nine hundred days I dig two hundred Acres of Ground; then I say, that the said Art which cost but one hundred days Invention is worth one Mans labour for ever; because the new Art, and one Man, perform'd as much as two Men could have done without it.
By the same way we make an Equation between Art and Opinion. For if a Picture-maker, suppose, make Pictures at 5l. each; but then, find that more Persons would employ him at that rate than his time would extend to serve them in, it will certainly come to pass that this Artist will consider whether as many of those who apply to him at 5l. each Picture, will give 6l. as will take up his whole time to accommodate; and upon this Computation he pitcheth the Rate of his Work. |67|
By the same way also an Equation may be made between drudging Labour, and Favour, Acquaintance, Interest, Friends, Eloquence, Reputation, Power, Authority, &c. All which I thought not amiss to intimate as of the same kind with finding an Equation between Land and Labour, all these not very pertinent to the Proportionation of the several Counties of Ireland.
Wherefore to return to the matter in hand, I say, that the Quantity of Commodity produced, and the Quantity of the shews the effects of the Land; and the number of People living thereupon, with the Quality of their housing,
