524 will yield to him, he will probably be willing to expend capital on it (for an immediate return) in any manner which will afford him a surplus profit, however small, beyond the value of the risk, and the interest which he must pay for the capital if borrowed, or can get for it elsewhere if it is his own. But a new farmer, entering on the land, would make his calculations differently, and would not commence unless he could expect the full rate of ordinary profit on all the capital which he intended embarking in the enterprise. Again, prices may range higher or lower during the currency of a lease, than was expected when the contract was made, and the land, therefore, may be over or under-rented: and even when the lease expires, the landlord may be unwilling to grant a necessary diminution of rent, and the farmer, rather than relinquish his occupation, or seek a farm elsewhere when all are occupied, may consent to go on paying too high a rent. Irregularities like these we must always expect; it is impossible in political economy to obtain general theorems embracing the complications of circumstances which may affect the result in an individual case. When, too, the farmer class, having but little capital, cultivate for subsistence rather than for profit, and do not think of quitting their farm while they are able to live by it, their rents approximate to the character of cottier rents, and may be forced up by competition (if the number of competitors exceeds the number of farms) beyond the amount which will leave to the farmer the ordinary rate of profit. The laws which we are enabled to lay down respecting rents, profits, wages, prices, are only true in so far as the persons concerned are free from the influence of any other motives than those arising from the general circumstances of the case, and are guided, as to those, by the ordinary mercantile estimate of profit and loss. Applying this twofold supposition to the case of farmers and landlords, it will be true that the farmer requires the ordinary rate of profit on the whole of his capital; that whatever it returns to him beyond this he is obliged
