 nobody but the landlord, who, being himself undertaker of the work, gets the ordinary profit of the capital which he employs in it. Many coal mines in Scotland are wrought in this manner, and can be wrought in no other. The landlord will allow nobody else to work them without paying some rent, and nobody can afford to pay any.

Other coal mines in the same country, sufficiently fertile, cannot be wrought on account of their situation. A quantity of mineral, sufficient to defray the expense of working, could be brought from the mine by the ordinary, or even less than the ordinary quantity of labor: but in an inland country, thinly inhabited, and without either good roads or water-carriage, this quantity could not be sold.

Coals are a less agreeable fuel than wood: they are said, too, to be less wholesome. The expense of coals, therefore, at the place where they are consumed, must generally be somewhat less than that of wood.

The price of wood again varies with the state of agriculture, nearly in the same manner, and exactly for the same reason, as the price of cattle. In its rude beginnings the greater part of every country is covered with wood, which is then a mere encumbrance of no value to the landlord, who would gladly give it to anybody for the cutting. As agriculture advances, the woods are partly cleared by the progress of tillage, and partly go to decay in consequence of the increased number of cattle. These, though they do not increase in the same proportion as corn, which is altogether the acquisition of human industry, yet multiply under the care and protection of men; who store up in the season of plenty what may maintain them in that of scarcity, who through the whole year furnish them with a greater quantity of food than uncultivated nature provides
