cottons, soap, and candles), they may be considered as independent of it; like the two remaining articles of tea and sugar, which are by no means unimportant in their amount.
It is manifest therefore that the whole of the wages of labour can never rise and fall in proportion to the variations in the price of grain. And that the effect produced by these variations, whatever may be its amount, must be very slow in its operation, is proved by the manner in which the supply of labour takes place; a point, which has been by no means sufficiently attended to.
Every change in the prices of commodities, if left to find their natural level, is occasioned by some change, actual or expected, in the state of the demand or supply. The reason why the consumer pays a tax upon any manufactured commodity, or an advance in the price of any of its component parts, is because, if he cannot or will not pay this advance of price, the commodity will not be supplied in the same quantity as before; and the next year there will only be such a proportion in the market, as is accommodated to the number of persons who will consent to pay the tax. But, in the case of labour, the operation of withdrawing the commodity is much slower and more painful. Although the purchasers refuse to pay the advanced price, the same supply will necessarily remain in the market, not only the next year, but for some years to come. Consequently, if no increase take place in the demand, and the advanced price of provisions be not so great, as to make it obvious that the labourer cannot support his family, it is probable, that he will continue to pay this advance, till a relaxation in the rate of the increase of population causes the market to be under-supplied with labour; and then, of course, the competition among the purchasers will raise the price above the proportion of the advance, in order to restore the supply. In the same manner, if an advance in the price of labour has taken place during two or three years of great scarcity, it is probable that, on the return of plenty, the real recompense of labour will continue higher than the usual average, till a too rapid increase of population causes a competition among the labourers, and a consequent diminution of the price of labour below the usual rate.
This account of the manner in which the price of corn may be expected to operate upon the price of labour, according to the laws which regulate the progress of population, evidently shows, that corn and labour rarely keep an even pace together; but must often be separated at a sufficient distance and for a sufficient time, to change the direction of capital.
As a further confirmation of this truth, it may be useful to consider, secondly, the consequences to which the assumption of Dr Smith's proposition would inevitably lead.
