Joseph Story,
Van Ness v. Mayor of Washington…
“ The streets and public squares are declared to be conveyed 'for the use of the United States for ever.' These are the very words which by law are required to vest an absolute unconditional fee simple in the United States. They are the appropriate terms of art, if we may so say, to express an unlimited use in the government. If the government were to purchase a lot of land for any general purpose, they are the very words which the conveyance would adopt, in order to grant an unlimited fee to the use of the government. ”
