Happy Fourth of July Mr. Jefferson

For more than 200 years, buried deep within Thomas Jefferson's correspondence and papers, there lay a mysterious cipher -- a coded message that appears to have remained unsolved. Until now.

    Very interesting. Just reading about it can easily get you confused, not mentioning trying to solve it

    But Mr. Patterson had a few more tricks up his sleeve. He wrote the message text vertically, in columns from left to right, using no capital letters or spaces. The writing formed a grid, in this case of about 40 lines of some 60 letters each.

    Then, Mr. Patterson broke the grid into sections of up to nine lines, numbering each line in the section from one to nine. In the next step, Mr. Patterson transcribed each numbered line to form a new grid, scrambling the order of the numbered lines within each section. Every section, however, repeated the same jumbled order of lines.
