592 inferior limit, of value. The produce which he carries to market, must bring in to him the value of all necessaries which he is compelled to purchase; and it must enable him to pay his rent. Rent, under peasant cultivation, is not governed by the principles set forth in the chapters immediately preceding, but is either determined by custom, as in the case of metayers, or, if fixed by competition, depends on the ratio of population to land. Rent, therefore, in this case, is an element of cost of production. The peasant must work until he has cleared his rent and the price of all purchased necessaries. After this, he will go on working only if he can sell the produce for such a price as will overcome his aversion to labour.

The minimum just mentioned is what the peasant must obtain in exchange for the whole of his surplus produce. But inasmuch as this surplus is not a fixed quantity, but may be either greater or less according to the degree of his industry, a minimum value for the whole of it does not give any minimum value for a definite quantity of the commodity. In this state of things, therefore, it can hardly be said, that the value depends at all on cost of production. It depends entirely on demand and supply, that is, on the proportion between the quantity of surplus food which the peasants choose to produce, and the numbers of the non-agricultural, or rather of the non-peasant population. If the buying class were numerous and the growing class lazy, food might be permanently at a scarcity price. I am not aware that this case has anywhere a real existence. If the growing class is energetic and industrious, and the buyers few, food will be extremely cheap. This also is a rare case, though some parts of France perhaps approximate to it. The common cases are, either that, as in Ireland until lately, the peasant class is indolent and the buyers few, or the peasants industrious and the town population numerous and opulent, as in Belgium, the north of Italy, and parts of Germany. The price of the produce will adjust itself to these varieties of circumstances,
