L’ENGLE.
At the New York Tribune reported in its expose on the topic
It was natural to suppose that this dispatch referred to the chief topic
of the day, and if so the word “canvass” must be in it somewhere.
The problem was, therefore, to find a combination of seven [pairs of]
numbers, of which the second and fifth, standing for A, should be the
same, and the sixth and seventh (SS) also the same. The translator
began at the beginning and tried every sequence of ciphers until at
the end of the twelfth line one was found which fulfilled the desired
conditions, namely, ...
what Find the set of 7 pairs of numbers that fit the letter pattern of
“canvass.” Then, with some frequency work, you should be able to decrypt
this cipher. Do so.
