But one of the evils apprehended by some, is a dissolution of the Union; and it is asked, if this has already been seriously threatened, how will it be when the sources of collision and rivalship shall be multiplied--when all fear of foreign aggression, which now operates as a band to keep us together, shall be removed--when personal ambition shall seek, by a separation, that field for its enterprises which the Union does not afford--and the natural increase of an indigent and ignorant class shall furnish him with ready tools for his selfish projects? But I do not see the probability that the proud hopes, which dictated a perpetual league among the states, are to be disappointed. It seems to me that the occasions in which their interests clash are few, compared with those in which they coincide, and that one of the strongest ligaments of union is the diversity of pursuits among the states, by which they are all benefited by a free commercial intercourse. Thus, some produce grain and cattle, others, fish, or sugar, or rice and cotton: some are exclusively agricultural in their pursuits, and are of course venders of raw produce, whilst others are manufacturing states, and purchasers of raw produce: some are largely concerned in navigation, whilst others are inland. Thus all are gainers by an interchange of their respective commodities and species of industry; and this mutual commerce, founded in mutual interests, will less and less require aid from the government. We may, moreover, reasonably expect, that these sources of mutual benefit and intercourse will increase, and that new products of agriculture and manufactures will arise under some propitious accident or kindness of nature, will extend the mutual dependence of the states, and proportionally multiply the bonds of union. Each state will be important to the rest for its useful products, and they in turn will be valuable to it, both for affording a market, and for the products they give in exchange. The commerce, too, will be the more profitable, and likely to be the more extensive, by its being free from imposts or vexatious restrictions. Under the fostering care of this freedom, we may expect that wine, and silk, and the olive may be added to the products of the south--and that whenever labor shall fall to the point of merely earning a subsistence, tea may be also cultivated; as no doubt some part of our country is similar in climate to China, since it is not only in a correspondent latitude, but on the same side of its continent.
