 ascribed to Edward III., would, in the then circumstances of the country, have been the most destructive regulation which could well have been thought of. It would not only have reduced the actual value of the greater part of the lands of the kingdom, but by reducing the price of the most important species of small cattle, it would have retarded very much its subsequent improvement.

The value of the greater part of the lands in the southern counties of Scotland, which are chiefly a sheep country, would have been very deeply affected by this event, had not the rise in the price of butcher's meat fully compensated the fall in the price of wool.

As the efficacy of human industry, in increasing the quantity either of wool or of raw hides, is limited, so far as it depends upon the produce of the country where it is exerted; so it is uncertain so far as it depends upon the produce of other countries. It so far depends, not so much upon the quantity which they produce, as upon that which they do not manufacture; and upon the restraints which they may or may not think proper to impose upon the exportation of this sort of rude produce.
