`  ==Re:  L'Enfant's and Ellicott's plans==  The picture is that of Ellicott's 1792 ``Plan of the City of Washington``.  The caption should therefore identify it as such.  The Library of Congress does not credit L'Enfant for Ellicott's engraving. The Library holds a copy of L'Enfant's 1791 ``Plan of the city intended for the permanent seat of the government ....``, which people can access at http://www.loc.gov/exhibits/treasures/tri001.html].   The Library of Congress also holds a copy of Ellicott's 1792 Plan. The picture in the Wikipedia site shows that plan.   Ellicott's plan was not a simple engraving of L'Enfant's Plan.  There are a number of significant differences between the two plans.  In fact, L'Enfant strenuously objected to the changes that Ellicott had made.   See the following webpage for more discussion of this subject: Plan of the City of Washington in Washington Map Society official website   I have added some information to the Streetscape section of the Washington, D.C. Wikipedia page that clarifies L'Enfant's and Ellicott's activities and plans.  The information contains references, including the above.    `
