234 commodities when any general and continuous cause operates to increase their price. As, during the rapid depreciation of currency which marked the latter days of the Southern Confederacy, the fact that whatever was bought one day could be sold for a higher price the next, operated to carry up the prices of commodities even faster than the depreciation of the currency, so does the steady increase of land values, which material progress produces, operate to still further accelerate the increase. We see this secondary cause operating in full force in those manias of land speculation which mark the growth of new communities; but though these are the abnormal and occasional manifestations, it is undeniable that the cause steadily operates, with greater or less intensity, in all progressive societies.

The cause which limits speculation in commodities, the tendency of increasing price to draw forth additional supplies, cannot limit the speculative advance in land values, as land is a fixed quantity, which human agency can neither increase nor diminish; but there is nevertheless a limit to the price of land, in the minimum required by labor and capital as the condition of engaging in production. If it were possible to continuously reduce wages until zero were reached, it would be possible to continuously increase rent until it swallowed up the whole produce. But as wages cannot be permanently reduced below the point at which laborers will consent to work and reproduce, nor interest below the point at which capital will be devoted to production, there is a limit which restrains the speculative advance of rent. Hence speculation cannot have the same scope to advance rent in countries where wages and interest are already near the minimum, as in countries where they are considerably above it. Yet that there is in all progressive countries a constant tendency in the speculative advance of rent to overpass the limit where production would cease, is, I think, shown by recurring seasons of industrial paralysis—a matter which will be more fully examined in the next book.
