The above article, “Calculating System Gas Balance”, written by my maternal grandfather, Ralph Scott Williams Jr., appeared on pages 65-68 of the May 1967 issue of Pipe Line Industry.  At the time the article was written, Ralph was a measurement superintendent for Columbia Gulf Transmission Company of Houston.  He passed away the following month, on 6/20/1967, while golfing in Charlottesville, Virginia.
