Mr. Rowland. Yes.
Mr. Specter. Did you have any impression or reaction as to the point of origin when you heard the first noise?
Mr. Rowland. Well, I began looking, I didn't look at the building mainly, and as practically any of the police officers that were there then will tell you, the echo effect was such that it sounded like it came from the railroad yards. That is where I looked, that is where all the policemen, everyone, converged on the railroads.
Mr. Specter. When you say railroad yards, what area are you referring to? Identify it on Commission Exhibit No. 354, for example?
Mr. Rowland. In this area in here.
Now most of the officers converged on this area——
Mr. Specter. When you say "in here," I will get a black pencil here and see if we can draw a circle around the area where you have described the echo effect?
Mr. Rowland. The echo effect felt as though it came from this general vicinity.
Mr. Specter. Mark that with the letter "C" in the center of your circle.
