addition. Upon which principle it may be observed, first, that whenever a mechanical invention succeeds in one place, it is necessary that it be imitated in every other where the same manufacture is carried on: for, it is manifest that he who has the benefit of a conciser operation, will soon outvie and undersell a competitor who continues to use a more circuitous labour. It is also true, in the second place, that whoever first discover or adopt a mechanical improvement, will, for some time, draw to themselves an increase of employment; and that this preference may continue even after the improvement has become general; for, in every kind of trade, it is not only a great but permanent advantage, to have once pre-occupied the public reputation. Thirdly, after every superiority which might be derived from the possession of a secret has ceased, it may be well questioned whether even then any loss can accrue to employment. The same money will be spared to the same article. still. Wherefore, in proportion as the article can be afforded at a lower price, by reason of an easier or shorter process in the manufac ture, it will either grow into more general use, or an improvement will take place in the

quality and fabric, which will demand a proportionable addition of hands. The number of persons employed in the manufactory of stockings has not, I apprehend, decreased since the invention of stocking-mills. The amount of what is expended upon the article, after subtracting from it the price of the raw material, and consequently what is paid for work in this branch of our manufactories, is not less than it was before. Goods of a finer texture are worn in the place of coarser. This is the change which the invention has produced; and which compensates to the manufactory for every other inconveniency. Add to which, that in the above, and in almost every instance, an improvement which conduces to the recommendation of a manufactory, either by the cheapness or the quality of the goods, draws up after it many dependent employments, in which no abbreviation has taken place.

From the reasoning that has been pursued, and the various considerations suggested in this chapter, a judgement may, in some sort, be formed, how far regulations of law are in

their nature capable of contributing to the support and advancement of population. I say how far for, as in many subjects, so especially in those which relate to commerce, to plenty, to riches, and to the number of people, more is wont to be expected from laws, than laws can do. Laws can only imperfectly restrain that dissoluteness of manners, which, by diminishing the frequency of marriages, impairs the very source of population. Laws cannot regulate the wants of mankind, their mode of living, or their desire of those superfluities which fashion, more irresistible than laws, has once introduced into general usage; or, in other words, has erected into necessaries of life. Laws cannot induce men to enter into marriages, when the expenses of a family must deprive them of that system of accommodation to which they have habituated their expectations. Laws, by their protection, by assuring to the labourer the fruit and profit of his labour, may help to make a people industrious; but, without industry, the laws cannot provide either subsistence or employment; laws cannot make corn grow without toil and care; or trade flourish without art and diligence. In spite of all laws, the ex

pert, laborious, honest workman will be employed, in preference to the lazy, the unskilful, the fraudulent, and evasive: and this is not more true of two inhabitants of the same village, than it is of the people of two different countries, which communicate either with each other, or with the rest of the world. The natural basis of trade is rivalship of quality and price; or, which is the same thing, of skill and industry. Every attempt to force trade by operation of law, that is, by compelling persons to buy goods at one market, which they can obtain cheaper and better from another, is sure to be either eluded by the quick-sightedness and incessant activity of private interest, or to be frustrated by retaliation. One half of the commercial laws of many states are calculated merely to counteract the restrictions which have been imposed by other states. Perhaps the only way in which the interposition of law is salutary in trade, is in the prevention of frauds.

Next to the indispensable requisites of internal peace and security, the chief advantage which can be derived to population from the interference of law, appears to me to consist in the encouragement of agricul

ture. This, at least, is the direct way of increasing the number of the people: every other mode being effectual only by its influence upon this. Now the principal expedient by which such a purpose can be promoted, is to adjust the laws of property, as nearly as possible, to the following rules: first," to give to the occupier all the power "over the soil which is necessary for its "perfect cultivation;"-secondly," to assign "the whole profit of every improvement to "the persons by whose activity it is carried " on." What we call property in land, as hath been observed above, is power over it. Now it is indifferent to the public in whose hands this power resides, if it be rightly used; it matters not to whom the land belongs, if it be well cultivated. When we lament that great estates are often united in the same hand, or complain that one man possesses what would be sufficient for a thousand, we suffer ourselves to be misled by words. The owner of ten thousand pounds a year, consumes little more of the produce of the soil than the owner of ten pounds a year. If the cultivation be equal, the estate in the hands of one great lord, affords subsistence and employment to the
