proportion as the price of produce.

And even when the price of labour does really rise in
proportion to the price of produce, which is a very rare case,
and can only happen when the demand for labour precedes, or is at
least quite contemporary with the demand for produce; it is so
impossible that all the other outgoings in which capital is
expended, should rise precisely in the same proportion, and at
the same time, such as compositions for tithes, parish rates,
taxes, manure, and the fixed capital accumulated under the former
low prices, that a period of some continuance can scarcely fail
to occur, when the difference between the price of produce and
the cost of production is increased.

In some of these cases, the increase in the price of
agricultural produce, compared with the cost of the instruments
of production, appears from what has been said to be only
temporary; and in these instances it will often give a
considerable stimulus to cultivation, by an increase of
agricultural profits, without showing itself much in the shape of
rent. It hardly ever fails, however, to increase rent ultimately.
The increased capital, which is employed in consequence of the
opportunity of making great temporary profits, can seldom if ever
be entirely removed from the land, at the expiration of the
current leases; and, on the renewal of these leases, the landlord
feels the benefit of it in the increase of his rents.

Whenever then, by the operation of the four causes above
mentioned, the difference between the price of produce and the
cost of the instruments of production increases, the rents of
