SOLVING CIPHER SECRETS Edited by M. E. Ohaver

TRY YOUR WITS ON THE GREAT CODES AND CRYPTOGRAMS IN WHICH MEN HAVE MASKED THEIR MESSAGES OF LIFE AND DEATH

LYNN'S new cipher department appears to be hitting the spot. Readers are writing to congratulate us daily; readers are submitting solutions of the cipher F we published; and readers are sending in their own secret messages which they challenge the world to solve. We propose to entertain you more at length with these challenge cryptograms later. Meanwhile FLYNN'S will continue " Solving Cipher Secrets " under the expert editorship of Mr. Ohaver as a regular department. Through practical application it will offer a synopsis of puzzle-making through the centuries. At the same time it will give our readers a problem on which to exercise their analytical powers at regular intervals. Set your teeth for a try at this juicy specimen from England's history.
