Mr. Arce. Three.
Mr. Ball. Where did you make out the direction of the sound?
Mr. Arce. Yeah, I thought they came from the railroad tracks to the west of the Texas School Book Depository.
Mr. Ball. When you were on the grass, were you south where you were? Where were you with reference to the entrance to the Texas School Book Depository?
Mr. Arce. I was down to the west side, a little more to the west.
Mr. Ball. Were you west of the building itself?
Mr. Ball. You were not in front of the building?
Mr. Arce. I was directly in front, but then I walked a few steps down to the west side.
Mr. Ball. Where were you with reference to the west wall of the building?
