We got up early this morning and 71 a long walk after breakfast. We walked 72 the business section of the city. I told you yesterday that the city 73 larger than I thought it would be. Well, the business section is smaller than I thought it would be. I suppose that's 74 Washington is a special kind of city. 75 of the people in Washington work for the government.
About 9∶30 we went to the White House. It's 76 the public from 10 77 12, and there was a long line of people 78 to get in. We didn't have to wait very long, because the line moved pretty quickly.
The White House is really white. It 79 every year. And it seems very white, because it's got beautiful lawns 80 around it, with many trees and shrubs. The grounds 81 about four square blocks. I mean, they're about two blocks long 82 each side.
Of course, we didn't see the whole building. The part 83 the President lives and works is not open to the publiC．But the part we saw was beautiful. We went through five of the main rooms. One of 84 was the library, on the ground floor. On the next floor, there are three rooms named 85 the colors that are used in them: the Red Room, the Blue Room, and the Green Room. The walls are covered with silk 86 . There are 87 old furniture, from the time 88 the White House was 89 built. And everywhere there are paintings and statues of former presidents and 90 famous people from history.

74
