The original, leading, main cause, then, of all our difficulties and disasters, is the disordered state of the circulation. This is, perhaps, not a perfectly obvious truth; and yet it is one susceptible of easy demonstration. In order to explain this the more readily, I wish to bring your minds to the consideration of the internal condition, and the vast domestic trade, of the United States. Our country is not a small province or canton, but an empire, extending over a large and diversified surface, with a population of various conditions and pursuits. It is in this variety that consists its prosperity; for the different parts become useful one to the other, not by identity, but by difference, of production, and thus each by interchange contributes to the interest of the other. Hence, our internal trade, that which carries on this exchange of the products and industry of the different portions of the United States, is one of our most important interests, I had almost said the most important. Its operations are easy and silent, not always perceptible, but diffusing health and life throughout the system by the intercourse thus promoted, from neighborhood to neighborhood, and from State to State. This circuit of trade, in a country of such great extent as ours, demands, more than in any country under heaven, a uniform currency for the whole people; that what is money in Carolina shall be so elsewhere; that what the Kentucky drover receives, what the planter of Alabama sells for, what the laborer in New York gets in pay for his work, and carries home to support his family, shall be of ascertained and uniform value. This is not the time nor the occasion for an essay or dissertation on money; but I mean distinctly to express the opinion, that until the general government shall take in hand the currency of the country, until that government shall devise some means, I say not what, of raising the whole currency to the level of gold and silver, there can be no prosperity.
