OdflMOMW CUIR 27 th Odtober, 1980 Following Alan Heard's return to GRIDC, he mentioned that he had spent some time talking about coal retention: I believe with Cathy McBride. As I understood it, you have undertaken some more development of the B. a 1-1. method and are getting sensible results with Virginia cigarettes. Further, it seems that you may be beginning to work out some correlations between coal retention and other physical characteristics.
