DORIS of the staff of the "Cincinnati Enquirer" furnished the Cincinnati Office with the enclosed letter and envelope received anonymously at the "Cincinnati Enquirer" in an envelope postmarked 7-3-52 at Cincinnati, Ohio. It will be noted that the enclosed letter is written in the German language, and I am also enclosing a rather loose translation of the letter as furnished by the "Cincinnati Enquirer." In view of the widespread interest in so-called "flying saucers," I am forwarding this material to the Bureau, with the thought in mind that the Bureau may desire to have a careful translation made of the attached letter, and the results, if deemed advisable, made available to other Governmental agencies.
