By the extension, besides, of cultivation, the unimproved wilds become insufficient to supply the demand for butcher's meat. A great part of the cultivated lands must be employed in rearing and fattening cattle; of which the price, therefore, must be sufficient to pay, not only the labour necessary for tending them, but the rent which the landlord, and the profit which the farmer, could have drawn from such land employed in tillage. The cattle bred upon the most uncultivated moors, when brought to the same market, are, in proportion to their weight or goodness, sold at the same price as those which are reared upon the most improved land. The proprietors of those moors profit by it, and raise the rent of their land in proportion to the price of their cattle. It is not more than a century ago, that in many parts of the Highlands of Scotland, butcher's meat was as cheap or cheaper than even bread made of oatmeal. The Union opened the market of England to the Highland cattle. Their ordinary price, at present, is about three times greater than at the beginning of the century, and the rents of many Highland estates have been tripled and quadrupled in the same time. In almost every part of Great Britain, a pound of the best butcher's meat is, in the present times, generally worth more than two pounds of the best white bread; and in plentiful years it is sometimes worth three or four pounds.
