_Def. 23._ It is this gross surplus of the land which furnishes the means of subsistence to the inhabitants of towns and cities. Besides the rents of land, which are powerfully effective in this respect, a large part of what, in the division of the produce of land, would fall to the shares of the farmers and labourers, is exchanged by them for other objects of convenience and gratification, thus giving the main necessaries of life to a great mass of persons not immediately connected with the soil. The proportion which this mass of persons may bear to the cultivators will depend upon the natural fertility of the soil, and the skill with which it has been improved, and continues to be worked. _Defs. 28 and 30._ In a valuable publication on the _Price of Corn, and Wages of Labour_, by Sir Edward West, which has just fallen into my hands, he proposes that the _price of labour_ should mean the sum paid for a given quantity of labour of a given character. I quite agree with him in thinking that it would be useful to have some appropriate term to express this meaning; but, as the _price of labour_ has certainly not hitherto been used in this sense, and as it would be, in almost all cases, extremely difficult to give an answer to a question respecting the price of labour so understood, it would certainly be proper to vary the expression in some degree, in order to prepare people for a new meaning. In Definition 30, therefore, I have given this meaning to _The price of effective labour_. _Def. 31._ It would save time and circumlocution, which is one of the great objects of appropriate terms, if, in speaking of the labour worked up in commodities, the labour worked up in the capital necessary to their production were designated by the term _accumulated labour_, as contradistinguished from the _immediate labour_ employed by the last capitalist. We must always recollect, however, that labour is not the only element worked up in capital.
