Note E — THE MEASURE OF VALUE.

Agricultural labour is taken for the obvious reasons that it is the commonest species of labour, that it directly produces the food of the labourer, and that it is the most immediately connected with the gradations of soil, and the necessary variations of profits. It is also assumed with Adam Smith, Mr. Ricardo, and other political economists, that, on an average, other kinds of labour continue to bear the same proportions to agricultural labour.
