only a part of this number, together with an amount of materials, or other advances consumed in the same time, equal to the labour of the other part, then upon a rise in the corn wages of labour, if the other advances were to fall, or not to be worth so much labour as before, it is obvious that the profits of stock would not fall so much as if the same rise of corn wages had taken place, when all the advances had been in labour; and it might be thought at first that profits not falling in proportion to the rise of labour, the value of labour would not continue the same. But it will be observed, that, in all cases of this kind, there will be a less value of labour, which is equivalent to a less quantity of it employed to obtain the same produce; and a less quantity of labour altogether being consequently necessary to produce the food of the labourer, than if labour alone had been employed, the higher profits, or smaller diminution of the former profits, will only just be such as to maintain labour of a constant value.
Let us suppose, for instance, that 120 quarters of corn are produced by ten men. If each man were paid ten quarters, profits would be 20 per cent.; and if wages were increased to eleven quarters, profits would fall from 20 per
