land will rise.

It is, however, not necessary that all these four causes
should operate at the same time; it is only necessary that the
difference here mentioned should increase. If, for instance, the
price of produce were to rise, while the wages of labour, and the
price of the other branches of capital did not rise in
proportion, and at the same time improved modes of agriculture
were coming into general use, it is evident that this difference
might be increased, although the profits of agricultural stock
were not only undiminished, but were to rise decidedly higher.

Of the great additional quantity of capital employed upon the
land in this country, during the last twenty years, by far the
greater part is supposed to have been generated on the soil, and
not to have been brought from commerce or manufactures. And it
was unquestionably the high profits of agricultural stock,
occasioned by improvements in the modes of agriculture, and by
the constant rise of prices, followed only slowly by a
proportionate rise in the different branches of capital, that
afforded the means of so rapid and so advantageous an
accumulation.

In this case cultivation has been extended, and rents have
risen, although one of the instruments of production, capital,
has been dearer.

In the same manner a fall of profits and improvements in
agriculture, or even one of them separately, might raise rents,
notwithstanding a rise of wages.
