Editor's Notes
Read in papers of your process for separating gold from tailings. Have patented machine to wash and screen tailings, recover 95% of gold using no quicksilver or chemicals. By hand or power. Maybe of interest to you; a combination of processes may be of mutual advantage. Marg: "Have you a descriptive circular of your apparatus."
