in the president's honor, and the district Columbia, which was a poetic name for the United States commonly in use at that time. Construction on the White House (then called the President's House) was begun in 1792. Washington laid the cornerstone for the United States Capitol (then called the Congress House) on September 18, 1793. John Adams, Washington's successor, moved into the White House in November 1800; that same month, Congress held its first session in the Capitol. The following February, Congress approved the District of Columbia Organic Act of 1801, which officially organized the District of Columbia, and, in accordance with the Constitution, named Congress as its exclusive governing authority. Tariff of 1789 One of the most pressing issues facing the First Congress during its inaugural session was the issue of how to raise revenue for the federal government. Because direct taxes were politically unfeasible, Congress turned to the tariff as the main source of funding. The tariffs could also protect nascent American manufacturing by increasing the cost of imported goods, many of which came from Britain. Each region sought favorable terms for the duties on various goods. Because the federal government would be unable to even pay the salaries of its officials without passage of the bill, members of Congress were strongly motivated to reach a compromise. In July, Congress finally passed the Tariff of 1789, which Washington signed into law. The act created a uniform impost on goods carried by foreign ships, while also establishing a much smaller tax on goods carried by American-owned ships. The tariffs established by this and later acts would make up the vast majority of government revenue; more than 87 percent of the federal government's revenue between 1789 and 1800 came from import duties. To enable the federal government to collect the import duties, Congress also passed the Collection Act of 1789, which established the United States Customs Service and designated ports of entry. One year later, the Revenue-Marine was established when Washington signed legislation authorizing construction of ten cutters to enforce federal tariff and trade laws and to prevent smuggling. Until Congress established the Navy Department in 1798, it served as the nation's only armed force afloat. Renamed a century later as the Revenue Cutter Service, it and the U.S. Life-Saving Service were merged in 1915 to form the United States Coast Guard. pp. 193–195 Hamiltonian economic program After the passage
