Mr. SPECTER. Now, would you indicate, if you know, which is a generally northerly direction on that picture? Mr. HILL. Yes, sir. Mr. SPECTER. All right. What was the condition of the crowd as the motorcade made a right-hand turn off of Main Street onto Houston? Mr. HILL. The crowd was very large on Main Street, and it was thinning down considerably when we reached the end of it, and turned right on Houston Street. Noticeably on my side of the car, which was the left-hand side of the street. Mr. SPECTER. And what is your best estimate as to the speed of the President's car at the time it made the right-hand turn onto Houston Street? Mr. HILL. In the curve? Mr. SPECTER. The speed--in the curve itself; yes. Mr. HILL. We were running generally 12 to 15 miles per hour. I would say that in the curve we perhaps slowed to maybe 10 miles per hour. Mr. SPECTER. And how far behind the President's car was the Presidential followup car as the turn was made onto Houston Street? Mr. HILL. Four to five feet, at the most. Mr. SPECTER. I show you a photograph of a building which has already been marked as Commission Exhibit No. 348, and ask you if at this time you can identify what that building is. Mr. HILL. I believe I can, sir; yes. Mr. SPECTER. And what building is it? Mr. HILL. It is the Texas School Book Depository. Mr. SPECTER. Now, does that building appear on the Commission Exhibit No. 354? Mr. HILL. Yes, sir; it does. Mr. SPECTER. Did you have any occasion to notice the Texas School Book Depository Building as you proceeded in a generally northerly direction on Houston Street? Mr. HILL. Yes, sir. It was immediately in front of us and to our left. Mr. SPECTER. Did you notice anything unusual about it? Mr. HILL. Nothing more unusual than any other building along the way. Mr. SPECTER. What is your general practice, if any, in observing such buildings along the route of a Presidential motorcade? Mr. HILL. We scan the buildings and look specifically for open windows, for people hanging out, and there had been, on almost every building along the way, people hanging out, windows open. Mr. SPECTER. And did you observe, as you recollect at this moment, any open windows in the Texas School Depository Building? Mr. HILL. Yes, sir; there were. Mr. SPECTER. Are you able to recollect specifically which windows were open at this time? Mr. HILL. No, sir; I cannot. Mr. SPECTER. What was the condition of the crowd along the streets, if any, along Elm Street, in front of the Texas School Book Depository Building? Mr. HILL. On the left-hand side of the street, which is the side I was on, the crowd was very thin. And it was a general park area. There were people scattered throughout the entire park. Mr. SPECTER. Now, what is your best estimate of the speed of the President's automobile as it turned left off of Houston onto Elm Street?
