The general principles which direct a statesman in the proper encouragement of this commerce, relate to two objects.

1. To promote the ease and happiness of the higher classes in making their wealth subservient to their wants and inclinations.

2. To promote the ease and happiness of the lower classes, by turning their natural faculties to an infallible means of relieving their necessities.

This communicates the idea of a free society; because it implies the circulation of a real equivalent for every service; to acquire which, mankind submit with pleasure to the hardest labour.

In the first book, I had little occasion to consider trade under different denominations; or as influenced by any other principle than that of promoting the multiplication of mankind, and the extension of agriculture, by drawing the wealth of the rich into the hands of the industrious. This operation, when carried no farther, is a true representation of infant trade.

But now I must set the matter in a new light: and consider this infant trade as a basis for establishing a foreign commerce. In itself it is only a means of gratifying the desires of those who have the equivalent; and of providing it for those who have it not. We are next to examine how, by the care of a statesman, it may prove a method whereby one society may be put in a situation to acquire a superiority over others; by diminishing, on one hand, the quantity they have of that general equivalent, and by increasing, on the other, the absolute quantity of it at home; in such a manner as not only to promote the circulation of that part of it which is necessary to supply the wants of all the citizens; but by a surplus of it, to render other nations dependent upon them, in most operations of their political oeconomy.

The statesman who resolves to improve this infant trade into foreign commerce, must examine the wants of other nations, and consider the productions of his own country. He must then determine, what kinds of manufactures are best adapted for supplying the first, and for consuming the latter. He must introduce the use of such manufactures among his subjects; and endeavour to extend his population, and his agriculture, by encouragements given to these new branches of consumption. He must provide his people with the best masters; he must supply them with every useful machine; and above all, he must relieve them of their work, when home demand is not sufficient for the consumption of it.

A considerable time must of necessity be required to bring a people to a dexterity in manufactures. The branches of these are many; and every one requires a particular slight of hand, and a particular master, to point out the rudiments of the art. People do not perceive this inconveniency, in countries where they are already introduced; and many a projector has been ruined for want of attention to it.

In the more simple operations of manufacturing, where apprenticeships are not in use, every one teaches another. The new beginners are put among a number who are already perfect: all the instructions they get, is, do as you see others do before you. This is an advantage which an established industry has over another newly set on foot; and this I apprehend to be the reason why we see certain manufactures, after remaining long in a state of infancy, make in a few years a most astonishing progress. What loss must be at first incurred! what numbers of aspiring geniuses overpowered by unsuccessful beginnings, when a statesman does not concern himself in the operation! If he assists his subjects, by a prohibition upon foreign work, how often do we see this expedient become a means of extending the most extravagant profits? Because he neglects, at the same time, to extend the manufacture by multiplying the hands employed in it. I allow, that as long as the gates of a kingdom are kept shut, and that no foreign communication is permitted, large profits do little harm; and tend to promote dexterity and refinement. This is a very good method for laying a foundation for manufactures: but so soon as the dexterity has been sufficiently encouraged, and that abundance of excellent masters are provided, then the statesman ought to multiply the number of scholars; and a new generation must be brought up in frugality, and in the enjoyment of the most moderate profits, in order to carry the plan into execution.

The ruling principle, therefore, which ought to direct a statesman in this first species of trade, is to encourage the manufacturing of every branch of natural productions, by extending the home-consumption of them; by excluding all competition with strangers; by permitting the rise of profits, so far as to promote dexterity and emulation in invention and improvement; by relieving the industrious of their work, as often as demand for it falls short. And until it can be exported to advantage, it may be exported with loss, at the expence of the public. To spare no expence in procuring the ablest masters in every branch of industry, nor any cost in making the first establishments; providing machines, and every other thing necessary or useful to make the undertaking succeed. To keep constantly an eye upon the profits made in every branch of industry; and so soon as he finds, that the real value of the manufacture comes so low as to render it exportable, to employ the hands, as above, and to put an end to these profits he had permitted only as a means of bringing the manufacture to its perfection. In proportion as the prices of every species of industry are brought down to the standard of exportation, in such proportion does this species of trade lose its original character, and adopt the second.
