Radlinski, Acting Director Free on application to the U.S. Geological Survey, Washmgton, D.C 20242 Brown Mountain--in the Blue Ridge country of western North Carolina--is the stage and setting for the intermit tent performances of the "mysterious lights" that have provoked legend and song since the beginning of the century. In 1922, responding t0 a general inter est in the lights, tt U.S. Geological Survey sent geologist George R. Mansfield to Brown Mountain to under take a thorough investigation of the reported phenomenon. Mansfield's meth od of study and his conclusions were released to the press in 1922. Because of the present interest in Brown Moun tain shown by visitors to this scenic area, George R. Mansfield's report to the press is reproduced here just as it was written a half century ago.
