[D8818AGH], Letter from Thomas Alva Edison to Brewer (Charles) & Co, March 15th, 1888

Title: [D8818AGH], Letter from Thomas Alva Edison to Brewer (Charles) & Co, March 15th, 1888
Editor's Notes: The sample you sent me is 30% magnetite and 70% sand. "Our machine will separate 100 tons of this in 24 hours, leaving the gold in the clean sand." TAE then suggests a couple way to extract the gold. [See Dickinson draft reply 880310 D8845AAH]
