The many important facilities for the construction of machines and the manufacturing of commodities which we possess, are enjoyed by no other country; nor is it likely that any country can enjoy them to an equal extent for an indefinite period. It is admitted by everyone, that our skill is unrivalled; the industry and power of our people unequalled; their ingenuity, as displayed in the continuol improvement in machinery, and production of commodities, without parallel; and apparently, without limit. The freedom which, under our government, every man has, to use his capital, his labour, and his talents, in the manner most conducive to his interests, is an inestimable advantage; canals are cut, and railroads constructed, by the voluntary association of persons whose local knowledge enables them to place them in the most desirable situations; and these great advantages cannot exist under less free governments. These circumstances, when taken together, give such a decided superiority to our people, that no injurious rivalry, either in the construction of machinery or the manufacture of commodities, can reasonably be anticipated. 442. But, even if it were desirable to prevent the exportation of a certain class of machinery, it is abdundantly evident, that, whilst the exportation of other classes is allowed, it is impossible to prevent the forbidden one from being smuggled out; and that, in point of fact, the additional risk has been well calculated by the smuggler. 443. It would appear, also, from various circumstances, that the immediate exportation of improved machinery is not quite so certain as has been assumed; and that the powerful principle of self-interest will urge the makers of it, rather to push the sale in a different direction. When a great maker of machinery has contrived a new machine for any particular process, or has made some great improvement upon those in common use, to whom will he naturally apply for the purpose of selling his new machines? Undoubtedly, in by far the majority of cases, to his nearest and best customers, those to whom he has immediate and personal access, and whose capability to fulfil any contract is best known to him. With these, he will communicate and offer to take their orders for the new machine; nor will he think of writing to foreign customers, so long as he finds the home demand sufficient to employ the whole force of his establishment. Thus, therefore, the machine-maker is himself interested in giving the first advantage of any new improvement to his own countrymen.
