OF THE PRICE OF COMMODITIES
119

following chapters, endeavor to explain, as fully and distinctly as I can, the causes of those different variations.

First, I shall endeavor to explain what are the circumstances which naturally determine the rate of wages, and in what manner those circumstances are affected by the riches or poverty, by the advancing, stationary, or declining state of the society.

Secondly, I shall endeavor to show what are the circumstances which naturally determine the rate of profit, and in what manner, too, those circumstances are affected by the like variations in the state of the society.

Though pecuniary wages and profit are very different in the different employments of labor and stock; yet a certain proportion seems commonly to take place between both the pecuniary wages in all the different employments of labor, and the pecuniary profits in all the different employments of stock. This proportion, it will appear hereafter, depends partly upon the nature of the different employments, and partly upon the different laws and policy of the society in which they are carried on. But though in many respects dependent upon the laws and policy, this proportion seems to be little affected by the riches or poverty of that society; by its advancing, stationary, or declining condition; but to remain the same or very nearly the same in all those different states. I shall, in the third place, endeavor to explain all the different circumstances which regulate this proportion.

In the fourth and last place, I shall endeavor to show what are the circumstances which regulate the rent of land, and which either raise or lower the real price of all the different substances which it produces.
