The present system of grating, undoubtedly tends more than the former system to diminish the quantity of human subsistence in the country, in proportion to the general fertility of the land.
I would not by any means be understood to say that the former system either could or ought to have continued.

The increasing price of butchers' meat is a natural and inevitable consequence of the general progress of cultivation; but I cannot help thinking, that the present great demand for butchers' meat of the best quality, and the quantity of good land that is in consequence annually employed to produce it, together with the great number of horses at present kept for pleasure, are the chief causes that have prevented the quantity of human food in the country from keeping pace with the generally increased fertility of the soil; and a change of custom in these respects would, I have little doubt, have a very sensible effect on the quantity of subsistence in the country, and consequently on its population.
The employment of much of the most fertile land in grating, the improvements in agricultural instruments, the increase of large farms, and particularly the diminution of the number of cottages throughout the kingdom, all concur to prove, that there are not probably so many persons employed in agricultural labour now as at the period of the Revolution.

Whatever increase of population, therefore, has taken place, must be employed almost wholly in manufactures, and it is well known that the failure of some of these manufactures, merely from the caprice of fashion, such as the adoption of muslins instead of silks, or of shoe-strings and covered buttons, instead of buckles and metal buttons, combined with the restraints in the market of labour arising from corporation and parish laws, have frequently driven thousands on charity for support.

The great increase of the poor rates is, indeed, of itself a strong evidence that the poor have not a greater command of the necessaries and conveniences of life, and if to the consideration, that their condition in this respect is rather worse than better, be added the circumstance, that a much greater proportion of them is employed in large manufactories, unfavourable both to health and virtue, it must be acknowledged, that the increase of wealth of late years has had no tendency to increase the happiness of the labouring poor.
That every increase of the stock or revenue of a nation cannot be considered as an increase of the real funds for the maintenance of labour and, therefore, cannot have the same good effect upon the condition of the poor, will appear in a strong light if the argument be applied to China.
Dr Adam Smith observes that China has probably long been as rich as the nature of her laws and institutions will admit, but that with other laws and institutions, and if foreign commerce were had in honour, she might still be much richer.

The question is, would such an increase of wealth be an increase of the real funds for the maintenance of labour, and consequently tend to place the lower classes of people in China in a state of greater plenty?
It is evident, that if trade and foreign commerce were held in great honour in China, from the plenty of labourers, and the cheapness of labour, she might work up manufactures for foreign sale to an immense amount.
