SPECIAL CLASS ASSIGNMENT

Each student will pick his/her ONE favorite cipher from "The
Cryptogram" for intensive study.  Plan on researching the
origin and history, use, methodology and "cracking"
techniques.  Be prepared to present and discuss with your
classmates when we cover it in class.  Be sure to include
available computer programs and appropriate references.



My best to all,
