when once a character of industry and economy has been established, temporary high profits are a more frequent and powerful source of accumulation, than either an increased spirit of saving, or any other cause that can be named. [19] It is the only cause which seems capable of accounting for the prodigious accumulation among individuals, which must have taken place in this country during the last twenty years, and which has left us with a greatly increased capital, notwithstanding our vast annual destruction of stock, for so long a period. Among the temporary causes of high price, which may sometimes mislead the landlord, it is necessary to notice irregularities in the currency. When they are likely to be of short duration, they must be treated by the landlord in the same manner as years of unusual demand. But when they continue so long as they have done in this country, it is impossible for the landlord to do otherwise than proportion his rent accordingly, and take the chance of being obliged to lessen it again, on the return of the currency to its natural state. The present fall in the price of bullion, and the improved state of our exchanges, proves, in my opinion, that a much greater part of the difference between gold and paper was owing to commercial causes, and a peculiar demand for bullion than was supposed by many persons; but they by no means prove that the issue of paper did not allow of a higher rise of prices than could be permanently maintained. Already a retrograde movement, not exclusively occasioned by the importations of corn, has been sensibly felt; and it must go somewhat further before we can return to payments in specie. Those who let their lands during the period of the greatest difference between notes and bullion, must probably lower them, whichever system may be adopted with regard to the trade in corn. These retrograde movements are always unfortunate; and high rents, partly occasioned by causes of this kind, greatly embarrass the regular march of prices, and confound the calculations both of the farmer and landlord. With the cautions here noticed in letting farms, the landlord may fairly look forward to a gradual and permanent increase of rents; and, in general, not only to an increase proportioned to the rise in the price of produce, but to a still further increase, arising from an increase in the quantity of produce. If in taking rents, which are equally fair for the landlord and tenant, it is found that in successive lettings they do not rise rather more than in proportion to the price of produce, it will generally be owing to heavy taxation.
