In economic conditions the United States were little more advanced than had been the colonies. The country abounded in natural resources: timber clad the whole Appalachian range, and spread far into the Mississippi valley; the virgin soil, and particularly the rich and untouched prairies of the West, were an accumulation of unmeasured wealth. Yet it was little easier to get from the sea to Lake Erie or to the Ohio than it had been forty years before. It seemed impossible that a country could be held together when it was so large that a courier might be two months on his way from the seat of government to the most distant frontier; and Jefferson predicted that it would be a thousand years before the country would be thickly settled as far west as the Mississippi. The chief resource of the country was agriculture; almost every State raised its own food, and there were considerable exports, particularly of wheat and flour. Manufactures were chiefly imported from England, the only widely known American industry being the distilling of New England rum. The chief source of wealth was still commerce; in 1790 the exports and imports were about twenty million dollars each, or five dollars per head of the population. The movement of vessels to foreign ports was tolerably free, but the vexatious restrictions and taxes imposed by England tended to throw an undue part of the profit into the hands of the English merchants. Business of every kind was much hampered by the want of bank capital and by the state of the currency. 72. POLITICAL METHODS IN 1789. [Sidenote: Current political theories.] The chief intellectual interest of the people was in politics. The State and the national constitutions both protected freedom of speech, and Americans were accustomed freely to discuss public men and public measures. Public opinion was, however, created by a comparatively small number of persons,--the leading planters of the South, merchants and great families in the Middle States, the gentlemen and clergy in New England. Already two different schools of political thought had appeared. The one is typified by John Adams's elaborate work, "The Defence of the American Constitutions," published in 1787. "The rich, the well-born, and the able," he says, "... must be separated from the mass and placed by themselves in a senate." The leading spirit in the other school was Thomas Jefferson. He wrote in 1787: "I am persuaded that the good sense of the people will always be found the best army. They may be led astray for a moment, but will soon correct themselves." The accepted principle of republican government was nevertheless that there should be a limited number of voters, following the lead of experienced statesmen of a higher social class.
