Hall in 1789, and the United States Bill of Rights was drafted in the city. The Supreme Court of the United States sat for the first time in New York. After 1790, Congress left for Philadelphia. Population growth and economic leadership New York remained a cosmopolitan enclave within America. The new French consul gave a report in 1810: "its inhabitants, who are for the most part foreigners and made up of every nation except Americans so to speak, have in general no mind for anything but business. New York might be described as a permanent fair in which two-thirds of the population is always being replaced; where huge business deals are being made, almost always with fictitious capital, and where luxury has reached alarming heights... It is in the countryside and in the inland towns that one must look for the American population of New York State." (quoted by Fernand Braudel, The Perspective of the World, 1984 p 406). The French consul's "fictitious capital" betokens the world of credit, on which New Yorkers' confidence has been based. The Commissioners' Plan of 1811 imposed a surveyed grid upon all of Manhattan's varied terrain, in a far-reaching though perhaps topographically insensitive vision. New York, with a population of 96,000 in 1810, surged far beyond its rivals, reaching a population of 1,080,000 in 1860, compared to 566,000 in Philadelphia, 212,000 in Baltimore and 178,000 in Boston. Historian Robert Albion identifies four aggressive moves by New York entrepreneurs and politicians that helped it jump to the top of American cities. Of greatest importance, it sponsored the Erie Canal, which began operations in 1825, forming a continuous water route from New York north to Albany via the Hudson River, then west to Buffalo using the new canal to reach the Great Lakes. It opened a large new market in upstate New York and the Old Northwest. New York set up an auction system that efficiently and rapidly sold imported cargoes to the highest bidder. Exporters from Britain discovered New York offered the best prices for their goods, and they increasingly ignored Boston and Philadelphia, where the local merchants tried to impose higher markups by avoiding auctions. New York began the world's first regular packet service to England with the Black Ball Line in 1818. By 1830, it dominated the nation's merchant marine. Ambitious shippers reached beyond the natural hinterland to open large-scale coastal trade, especially
