him,
"You undoubtedly know our dalle Caselle cipher?" "For that,
you have to skip a lot," he replied, meaning that he only knew
portions of it. I asked him to let me see some of our
deciphered letters, and he promised to let me, but since then
he has not spoken
further about it to me, and, having left, I have not seen him any
more.
