Mr. Dulles. That goes back to the time you were first employed there?
Mr. Williams. Yes, sir. At the time I came to the building.
Mr. Dulles. So it could not have been put up a day or two before.
Mr. Williams. No, sir.
Mr. Ball. Did you hear anyone going up or down the stairs?
Mr. Williams. No, I didn't.
Mr. Ball. Did you pay any attention to that?
Mr. Williams. No, sir.
Mr. Ball. As you were standing at the window, did you hear any footsteps?
Mr. Williams. No, sir.
