	Another example is the White House, located at 1600 Pennsylvania Avenue NW: it is located at 16th Street NW (Lafayette Square) and Pennsylvania Avenue NW. This works both ways; an address at 514 19th St NW would be on 19th St west of the Capitol, and since E is the fifth letter of the alphabet, the 514 address would be between E and F Streets NW. Because "J" is omitted from the scheme, it is not counted in numbering. Thus, the 900 block is in between I and K Streets, and the 1000 block is in between K and L Streets (even though K is the 11th letter of the alphabet).
