Thomas Edison autograph letter signed to his right hand man, Jaffrey Buchanan, at the Edison Chemical Factory. Two page letter, written in pencil in Edison's shorthand style, reads in full, ''We are having a rotten time with drying our powder its scandalous -- I want you to fix this up -- The drying time with constant steam heat is a function of the vacuum, the time diminishes much faster than directly as vac goes up. With a perfect vacuum no steam is needed at all water boils at ordinary temperature. I heard of water laying in bottom of Dryer of variation of vacuum from 21 to 13 This is rotten this is the most important job you can do, answer / Edison''. A sketch, possibly by Edison, is on the verso of page two. Light toning to two page 5'' x 8'' letter, else very good.
