Hebern: 8th Problem

Washington May 9, 1924

Dear Laurence,

This challenge is very similar to the last one but
the cryptogram is shorter.

Note: the keyboard and lampboard are both the
identity permutation.

Some information :

This telegram was sent from the Japanese
Embassy in Whasington to the Japanese
government in Tokyo on February 7, 1922. This
telegram is in English with the words separated
by the letter X. Here are some assumed key words:
calibre, tonnage, armament, displacement, naval,
treaty, japan, capital ship, aicraft carrier.

Good luck !
