The south lines of the 10-mile square--the Federal district in which the new Capital lay--were to run from the intersection of the Potomac River and the Eastern Branch, but, as has been related, by the act of March 3, 1791, these boundary lines were moved south to include Alexandria and part of Virginia within the Federal territory. The land lying within the bounds of the proposed city was given by the proprietors to trustees appointed by the Government under an agreement by which the Nation received the land necessary for streets without charge, purchasing the areas for parks and building sites at the rate of £25 per acre. The remaining land was divided equally with the original proprietors. The first settlements were made on grants given chiefly to retired naval officers who named their holdings after their camps--Mexico, Jamaica, and Port Royal. There were two settlements on the site--Carrollsburg, named after its founder, and Hamburg, an early real-estate development near and south of Georgetown. A stream of considerable size known originally as Goose Creek ran through the city. It later became known as Tiber Creek, because a resident named Pope, whose estate he facetiously called Rome, contended that if there was a Pope in Rome, his residence should be situated on the Tiber. As is noticed by reference to the plans, a canal extended from the point about where the Lincoln Memorial is located, along B Street, now Constitution Avenue, east to the Capitol; thence along James Creek, known to-day as Canal Street. In those days Pennsylvania Avenue was a dusty road, lined with poplar trees, and often so flooded that it was not an uncommon sight to see boats floating on it. For a long time an isolated group of buildings known as the Six Buildings at Twenty-first Street and Pennsylvania Avenue stood halfway between the Capitol and Georgetown.
