> A how-to technical leaflet by John Burke was published in the SPNHC Leaflet sent out with the SPNHC Newsletter last spring. I would be glad to send a complimentary copy if you would like. Dear Sally - Yes, I would very much like to receive a copy of the technical leaflet. We don't know yet what approach we will take to this problem, but we would like to avoid using any chemicals if possible. Thanks for your help. Susan G. Denney Assistant Curator of History Panhandle-Plains Historical Museum Canyon, Texas
