"That's good!" exclaimed Nan. "And shall we go up inside it?"
"I think so," her father replied.
Washington Monument, as a good many of you know, is not a solid shaft of stone. It is built of great granite blocks, as a building is built, and is, in fact, a building, for it has several little rooms in the base; rooms where men can stay who watch the big pointed shaft of stone, and other rooms where are kept the engines that run the elevator.
The bottom part of Washington Monument is square, and on one side is a doorway. Above the base the shaft itself stretches up over five hundred feet in height, and the top part is pointed, like the pyramids of the desert. The monument shaft is hollow, and there is a stairway inside, winding around the elevator shaft. Some people walk up the stairs to get to the top of the monument, where they can look out of small windows over the city of Washington and the Potomac River. But most persons prefer to go up and down in the elevator, though it is slow and, if there are many visitors they have to await their turns.
