of some Doctrines of Political Economy. 205 



It may be observed also, that the place which wages occupy 

 in this theory, is that of a mode of employing- capital ; and their 

 variations will depend on ithe supply of capital directed to such 

 an employment, along with the other causes which influence 

 their amount, and which do not belong to our present investiga- 

 tions. 



13. It follows from tlie 6th Axiom, that in determining the 

 price as in Art. 10, by the cost of production, we must consider, 

 as forming part of the cost, the tax paid. The price must be such 

 as to replace the capital with the usual profits and the tax; 

 for otherwise the capital would desert this employment. 



14. We have therefore six Axioms, viz. 



(1) Rent is = produce - profits. 



(2) Land will be cultivated if produce = or > than pj-ofits. 

 (.i) There is always a limiting soil. 



(4) Increase of price oc diminution of supply. 



(5) Price = cost of production + profits. 

 (b) Taxes do not affect the rate of profits. 



The results of the combination of these six principles, may, 

 as has been said, be most certainly and easily deduced by means 

 of mathematical reasoning, and we proceed to trace the conse- 

 quences of them in the case of taxes imposed on the produce of 

 land, as tithes, land-tax, rates, &c. 



15. Let it be supposed that there are various qualities of 

 soil, which we may call the 1st, 2nd, 3rd ... wi"" ... w'" : that the 

 quantities of each of these soils are respectively «i, «,, a,.. .a,,,.. .a,, 

 acres or units of land : that the capital employed on one acre 

 in the different ca.ses is respectively c,, c,,, c,...c,„...c„ shillings, or 

 units of money : that the jiroduce of one acre of each quality, 

 is respectively r,, n, r,...r„,...r„ quarters or units of produce. Let 

 it be supposed also, that the price of a quarter (or other unit) of
