must observe that what we have said of agriculture, is true, with little variation, of the other occupations which it represents; of all the arts which extract materials from the globe. Mining industry, for example, usually yields an increase of produce at a more than proportional increase of expense. It does worse, for even its customary annual produce requires to be extracted by a greater and greater expenditure of labour and capital. As a mine does not reproduce the coal or ore taken from it, not only are all mines at last exhausted, but even when they as yet show no signs of exhaustion, they must be worked at a continually increasing cost; shafts must be sunk deeper, galleries driven farther, greater power applied to keep them clear of water; the produce must be lifted from a greater depth, or conveyed a greater distance. The law of diminishing return applies therefore to mining, in a still more unqualified sense than to agriculture but the antagonizing agency, that of improvements in production, also applies in a still greater degree. Mining operations are more susceptible of mechanical improvements than agricultural: the first great application of the steam-engine was to mining; and there are unlimited possibilities of improvement in the chemical processes by which the metals are extracted. There is another contingency, of no unfrequent occurrence, which avails to counterbalance the progress of all existing mines towards exhaustion: this is, the discovery of new ones, equal or superior in richness.

To resume; all natural agents which are limited in quantity, are not only limited in their ultimate productive power, but, long before that power is stretched to the utmost, they yield to any additional demands on progressively harder terms. This law may however be suspended, or temporarily controlled, by whatever adds to the general power of mankind over nature; and especially by any extension of their knowledge, and their consequent command, of the properties and powers of natural agents.

CHAPTER XIII.

CONSEQUENCES OF THE FOREGOING LAWS.

§ 1. FROM the preceding exposition it appears that the limit to the increase of production is two-fold; from deficiency of capital, or of land. Production comes to a pause, either because the effective desire of accumulation is not sufficient to give rise to any further increase of capital, or because, however disposed the possessors of surplus income may be to save a portion of it, the limited land at the disposal of the community does not permit additional capital to be employed with such a return, as would be an equivalent to them for their abstinence.

In countries where the principle of accumulation is as weak as it is in the various nations of Asia; where people will neither save, nor work to obtain the means of saving, unless under the inducement of enormously high profits, nor even then if it is necessary to wait a considerable time for them; where either productions remain scanty, or drudgery great, because there is neither capital forthcoming nor forethought sufficient for the adoption of the contrivances by which natural agents are made to do the work of human labour; the desideratum for such a country, economically considered, is an increase of industry, and of the effective desire of accumulation. The means are, first, a better government: more complete security of property; moderate taxes, and freedom from arbitrary exaction under the name of taxes; a more permanent and more advantageous tenure of land, securing to the cultivator as far as possible the undi

vided benefits of the industry, skill, and economy he may exert. Secondly, improvement of the public intelligence: the decay of usages or superstitions which interfere with the effective employment of industry; and the growth of mental activity, making the people alive to new objects of desire. Thirdly, the introduction of foreign arts, which raise the returns derivable from additional capital, to a rate corresponding to the low strength of the desire of accumulation and the importation of foreign capital, which renders the increase of production no longer exclusively depen dent on the thrift or providence of the inhabitants themselves, while it places before them a stimulating example, and by instilling new ideas and breaking the chains of habit, if not by improving the actual condition of the popula tion, tends to create in them new wants, increased ambition, and greater thought for the future. These considerations apply more or less to all the Asiatic populations, and to the less civilized and industrious part of Europe, as Russia, Hungary, Spain, and Ireland.

§ 2. But there are other countries, and England is at the head of them, in which neither the spirit of industry nor the effective desire of accumulation need any encouragement; where the people will toil hard for a small remuneration, and save much for a small profit; where, though the general thriftiness of the labouring class is much below what is desirable, the spirit of accumulation in the more prosperous part of the community requires abatement rather than increase. In these countries there would never be any deficiency of capital, if its increase were never checked or brought to a stand by too great a diminution of its returns. It is the tendency of the returns to a progressive diminution, which causes the increase of production to be often attended with a deterioration in the condition of the producers; and this tendency, which would in time put an end to increase of production altogether, is a result of the necessary and inherent conditions of production from the land.

In all countries which have passed beyond a very early stage in the progress of agriculture, every increase in the demand for food, occasioned by increased population, will always, unless there is a simultaneous improvement in production, diminish the share which on a fair division would fall to each individual. An increased production, in default of unoccupied tracts of fertile land, or of fresh improvements tending to cheapen commodities, can never be obtained but by increasing the labour in more than the same proportion. The population must either work harder, or eat less, or obtain their usual food by sacrificing a part of their other customary comforts. Whenever this necessity is postponed, it is because the improvements which facilitate production continue progressive; because the contriv ́ances of mankind for making their labour more effective, keep up an equal struggle with nature, and extort fresh resources from her reluctant powers as fast as human necessities occupy and engross the old.

From this, results the important corollary, that the necessity of restraining population is not, as many persons believe, peculiar to a condition of great inequality of property. A greater number of people cannot, in any given state of civilization, be collectively so well provided for as a smaller. The niggardliness of nature, not the injustice of society, is the cause of the penalty attached to over-population. An unjust distribution of wealth does not even aggravate the evil, but, at most, causes it to be somewhat earlier felt. It is in vain to say, that all mouths which the increase of mankind calls into existence bring with them hands. The new mouths require as much food as the old ones, and the hands do not produce as much. If all instruments of production were held in joint property by the whole people, and the produce divided with perfect equality among them, and if in a society thus constituted, industry were as energetic and the produce as ample as at present, there would be enough to make all the existing population extremely comfortable; but when that population had doubled itself,

as, with the existing habits of the people, under such an encouragement, it undoubtedly would in little more than twenty years, what would then be their condition? Unless the arts of production were in the same time improved in an almost unexampled degree, the inferior soils which must be resorted to, and the more laborious and scantily remunerative cultivation which must be employed on the superior soils, to procure food for so much larger a population, would, by an insuperable necessity, render every individual. in the community poorer than before. If the population continued to increase at the same rate, a time would soon arrive when no one would have more than mere necessaries, and, soon after, a time when no one would have a sufficiency of those, and the further increase of population would be arrested by death.

Whether, at the present or any other time, the produce of industry, proportionally to the labour employed, is increasing or diminishing, and the average condition of the people improving or deteriorating, depends upon whether population is advancing faster than improvement, or improvement than population. After a degree of density has been attained, sufficient to allow the principal benefits of combination of labour, all further increase tends in itself to mischief, so far as regards the average condition of the people; but the progress of improvement has a counteracting operation, and allows of increased numbers without any deterioration, and even consistently with a higher average of comfort. Improvement must here be understood in a wide sense, including not only new industrial inventions, or an extended use of those already known, but improvements in institutions, education, opinions, and human affairs generally, provided they tend, as almost all improvements do, to give new motives or new facilities to production. If the productive powers of the country increase as rapidly as advancing numbers call for an augmentation of produce, it is not necessary to obtain that augmentation by the cultivation of soils more sterile than the worst already under culture, or
