More than ever had I the conviction upon me that the reading of the secret writing would be the first step to the attainment of my wishes regarding Marjory. It would have been strange therefore if I had not first attempted the method which she had herself suggested, the reducing the Baconian cipher to its lowest elements.
For many hours I laboured at this work, and finally when I had reduced the Baconian five symbols to three I felt that I had accomplished all that was possible in that way.[1]
When I had arrived at this result, and had tested its accuracy in working, I felt in a position to experiment with my new knowledge on the old number cipher. First I wrote out my method of reduction as a sort of addendum to the paper which I had prepared for Marjory. Then I made a key to cipher and one to de-cipher.[2] By this time the night was well on and the grey of early morning was beginning to steal in by the edges of the blinds; I was not sleepy, however; I was too much excited to think of sleep, for the solving of the problem seemed almost within my grasp.
