All sudden revolutions are to be avoided. A sudden stop upon a large importation, raises the prices of domestic industry by jerks, as it were; they do not rise gradually; and these sudden profits engage too many people to endeavour to share in them. This occasions a desertion from other branches of industry equally profitable to the state. Such revolutions do great harm; because it is a long time before people come to be informed of their true cause, and during the uncertainty, they are, as it were, in a wilderness, surprized and delighted with the consequences, according as their several interests are affected by them. Every one accounts for the phenomena in a different way. Some are for applying remedies against the inconveniencies; while others are totally taken up in profiting to the utmost of every momentary advantage. In a word, nothing is more hurtful than a sudden revolution, in so complicated a body as that of the whole class of the industrious, in a modern society. When therefore such changes happen, in spite of all a statesman can do, the best way to prevent the inconveniencies which they draw along with them, is to inform the public of the true causes of every change, favourable or hurtful to the several classes of inhabitants. This also seems to be the best method to engage every one to concur in promoting the proper remedies, when the inconveniencies themselves cannot be prevented. So much for a scheme of encouraging growing manufactures, or of supporting them in their decline. I proceed next to consider the methods of preventing the loss of others already established. We have said, that the importation of any article of consumption usually provided at home, was a proof by no means equivocal of a foreign rivalship. I shall say nothing, at present, of the methods to be used as a remedy for this inconvenience: these have been already discussed. We must now suppose, every one that might be contrived for this purpose, to become ineffectual; and that foreign industry is so far gaining ground, as daily, more and more, to supply the several branches of domestic consumption. Upon this, the statesman will begin by laying the importation of such commodities under certain restrictions. If these do not prove sufficient, they must be increased; and if the augmentation produces frauds, difficult to be prevented, the articles must be prohibited altogether. By this method of proceeding, it will be found, that without any violent or sudden prohibition laid upon foreign trade, by little and little, every pernicious branch of it will be cut off, till at last it will cease altogether, as in the case mentioned above; to wit, when the most advantageous branches cannot be carried on without loss.
