Grain, the food of the common people, is dearer in Scotland than in England, whence Scotland receives almost every year very large supplies. But English corn must be sold dearer in Scotland, the country to which it is brought, than in England, the country from which it comes; and it proportion to its quality it cannot be sold dearer in Scotland than the Scotch corn that comes to the same market in competition with it. The quality of grain depends chiefly upon the quantity of flour or meal which it yields at the mill; and, in this respect, English grain is so much superior to the Scotch, that though often dearer in appearance, or in proportion to the measure of its bulk, it is generally cheaper in reality, or in proportion to its quality, or even to the measure of its weight. The price of labour, on the contrary, is dearer in England than in Scotland. If the labouring poor, therefore, can maintain their families in the one part of the united kingdom, they must be in affluence in the other. Oatmeal, indeed, supplies the common people in Scotland with the greatest and the best part of their food, which is, in general, much inferior to that of their neighbours of the same rank in England. This difference, however, in the mode of their subsistence, is not the cause, but the effect, of the difference in their wages; though, by a strange misapprehension, I have frequently heard it represented as the cause. It is not because one man keeps a coach, while his neighbour walks a-foot, that one is rich, and the other poor; but because the one is rich, he keeps a coach, and because the other is poor, he walks a-foot.
