Title
[D8034ZDP], Letter from Alex McGregor, Jr. to Thomas Alva Edison, July 13th, 1880
Editor's Notes
What terms can I get your process for saving gold from black sand? Old miners laugh at idea of getting gold that can't be seen. Is platina ever found in quartz? Knows good quartz (Calif) for gold. Marg: "We can work black sand containing flour & rusty flour gold so fine that you cant see it in a pan & can envision do it with the greatest economy & facility requires no water. Give me more information."
