UNIVERSITY OF MISSOURI COLUMBIA DEPARTMENT OF CHEMISTRY Barker - 2 mostly at Rolla. He already has the Master's Degree and a year of graduate training in the Carnegie Institute of Tech- nology He expects to do his thesis on a problem in electro. magnetic concentration of ores, especially by the alternating current method. Of course I have taken occasion to bring to his attention the possibility of trying some of his experiments on these carnotite ores. It thus seems to me that we have at least made a start on this problem. With very good wishes, I remain, Sincerely yours, Herman Schlund Herman Schlundt. hs.as
