 saving improvements would be simply to reduce the amount of labor expended. But such a state of society, if it can anywhere be found, which I do not believe, exists only where the human most nearly approaches the animal. In the state of society called civilized, and which in this inquiry we are concerned with, the very reverse is the case. Demand is not a fixed quantity, that increases only as population increases. In each individual it rises with his power of getting the things demanded. Man is not an ox, who, when he has eaten his fill, lies down to chew the cud; he is the daughter of the horse leech, who constantly asks for more. "When I get some money," said Erasmus, "I will buy me some Greek books and afterward some clothes." The amount of wealth produced is nowhere commensurate with the desire for wealth, and desire mounts with every additional opportunity for gratification.

This being the case, the effect of labor-saving improvements will be to increase the production of wealth. Now, for the production of wealth, two things are required—labor and land. Therefore, the effect of labor-saving improvements will be to extend the demand for land, and wherever the limit of the quality of land in use is reached, to bring into cultivation lands of less natural productiveness, or to extend cultivation on the same lands to a point of lower natural productiveness. And thus, while the primary effect of labor-saving improvements is to increase the power of labor, the secondary effect is to extend cultivation, and, where this lowers the margin of cultivation, to increase rent. Thus, where land is entirely appropriated, as in England, or where it is either appropriated or is capable of appropriation as rapidly as it is needed for use, as in the United States, the ultimate effect of labor-saving machinery or improvements is to increase rent without increasing wages or interest.
