In the present commercial state of the known world, the most

barbarous nations, I believe, among whom land property is

established, have some foreign commerce of this kind, and find

among their wealthier neighbours such a demand for all the

materials of clothing, which their land produces, and which can

neither be wrought up nor consumed at home, as raises their price

above what it costs to send them to those wealthier neighbours.

It affords, therefore, some rent to the landlord. When the

greater part of the Highland cattle were consumed on their own

hills, the exportation of their hides made the most considerable

article of the commerce of that country, and what they were

exchanged for afforded some addition to the rent of the Highland

estates.
