Thirdly, as the price of provisions varies more from year to year than the wages of labour, so, on the other hand, the wages of labour vary more from place to place than the price of provisions. The prices of bread and butchers' meat are generally the same, or very nearly the same, through the greater part of the united kingdom. These, and most other things which are sold by retail, the way in which the labouring poor buy all things, are generally fully as cheap, or cheaper, in great towns than in the remoter parts of the country, for reasons which I shall have occasion to explain hereafter. But the wages of labour in a great town and its neighbourhood, are frequently a fourth or a fifth part, twenty or five-and-twenty per cent. higher than at a few miles distance. Eighteen pence a day may be reckoned the common price of labour in London and its neighborhood. At a few miles distance, it falls to fourteen and fifteen pence. Tenpence may be reckoned its price in Edinburgh and its neighbourhood. At a few miles distance, it falls to eightpence, the usual price of common labour through the greater part of the low country of Scotland, where it varies a good deal less than in England. Such a difference of prices, which, it seems, is not always sufficient to transport a man from one parish to another, would necessarily occasion so great a transportation of the most bulky commodities, not only from one parish to another, but from one end of the kingdom, almost from one end of the world to the other, as would soon reduce them more nearly to a level. After all that has been said of the levity and inconstancy of human nature, it appears evidently from experience, that man is, of all sorts of luggage, the most difficult to be transported. If the labouring poor, therefore, can maintain their families in those parts of the kingdom where the price of labour is lowest, they must be in affluence where it is highest. Fourthly, the variations in the price of labour not only do not correspond, either in place or time, with those in the price of provisions, but they are frequently quite opposite.
