Mr. Specter. Indicating a general westerly direction from the School Book Depository Building?
Mr. Gauthier. Yes; I am pointing towards the west.
On the east it is bounded by Houston Street.
On the south by Main, which is a roadway going through Dealey Plaza.
And on the west by the triple underpass.
Located on this plat map are street lights accurately located, a catch basin, certain trees, location of trees, the delineation of the concrete pergola, which you see here on the photograph, the outer boundaries of the pericycle, and the reflecting pool—locating exactly the window in the Texas School Book Depository Building, in the southeast corner, and also a tabulation of the measurements and angles that the surveyor has compiled from certain positions identified for him on the street by an observation from this window, an observation from the position of Mr. Zapruder——
Mr. Specter. When you say this window, which window did you mean?
Mr. Gauthier. The window on the sixth floor of the Texas School Book Depository Building, the one in the southeast corner, the farthest window.
Mr. Specter. And when you identify the Zapruder position, what did you mean by that?
Mr. Gauthier. This is a concrete abutment of the pergola, located in the area upon which Zapruder was standing at the time the movies were made.
