Mr. Ball. I see. And how many sets of tracks do you control from your tower?
Mr. Bowers. There are about 11 tracks in the station and 2 freight tracks.
Mr. Ball. That would be 13 tracks that is, the tracks altogether, that pass in front of your tower?
Mr. Bowers. Yes; of course where the tracks converge and cross and split off to various railroad yards——
Mr. Ball. And the tracks are to the north and west of your tower, aren't they?
Mr. Bowers. Well, the tracks are west, but they proceed in all directions, I mean, they are both north and south.
Mr. Ball. Now, you were on duty on November 22, 1963, weren't you?
Mr. Bowers. That's correct.
Mr. Ball. Close to noon, did you make any observation of the area around between your tower and Elm Street?
Mr. Bowers. Yes; because of the fact that the area had been covered by police for some 2 hours. Since approximately 10 o'clock in the morning traffic had been cut off into the area so that anyone moving around could actually be observed. Since I had worked there for a number of years I was familiar with most of the people who came in and out of the area.
