Between Maryland and Virginia, lies the Federal District of Columbia,
comprising a square of ten miles. This district which was given by
these States to the United States, lies on both sides of the river
Potomack, 120 miles from its mouth, and is under the immediate
jurisdiction of the National Congress, which assembles annually at
Washington, for the purpose of legislation. Washington is situated near
the centre of the district, and is laid out in such manner, that the
principal buildings, as the Capitol, President’s house, &c. command a
full view of the city, and at the same time can be seen from every part
of it. Georgetown and Alexandria are also within the district.
