518 yield nothing to any amount of labour; and there is land, like some of our hard sandy heaths, which would produce something, but, in the present state of the soil, not enough to defray the expenses of production. Such lands, unless by some application of chemistry to agriculture still remaining to be invented, cannot be cultivated for profit, unless some one actually creates a soil, by spreading new ingredients over the surface, or mixing them with the existing materials. If ingredients fitted for this purpose exist in the subsoil, or close at hand, the improvement even of the most unpromising spots may answer as a speculation: but if those ingredients are costly, and must be brought from a distance, it will seldom answer to do this for the sake of profit, though the "magic of property" will sometimes effect it. Land which cannot possibly yield a profit, is sometimes cultivated at a loss, the cultivators having their wants partially supplied from other sources; as in the case of paupers, and some monasteries or charitable institutions, among which may be reckoned the Poor Colonies of Belgium. The worst land which can be cultivated as a means of subsistence, is that which will just replace the seed, and the food of the labourers employed on it, together with what Dr. Chalmers calls their secondaries; that is, the labourers required for supplying them with tools, and with the remaining necessaries of life. Whether any given land is capable of doing more than this, is not a question of political economy, but of physical fact. The supposition leaves nothing for profits, nor anything for the labourers except necessaries: the land, therefore, can only be cultivated by the labourers themselves, or else at a pecuniary loss: and à fortiori, cannot in any contingency afford a rent. The worst land which can be cultivated as an investment for capital, is that which, after replacing the seed, not only feeds the agricultural labourers and their secondaries, but affords them the current rate of wages, which may extend to much more than mere necessaries; and leaves for those, who have advanced the wages of these two classes of
