A few years ago, a then-girlfriend gifted me this genuine Masonic handbook, printed in 1920, as a Christmas present. (I wish everyone had such a good understanding of my tastes.) The entirety of the manual is written in nigh-impenetrable code and shorthand, save passages like that in the middle of the left-hand page, quoting from Genesis.
From what I’ve read, Freemasons technically are disallowed from using printed guides like these, for the exact reason of dissemination by persons like myself. Seeing as it was published prior to 1923, it’s all public domain under U.S. copyright law anyhow. But even so, leafing through something so painstakingly shrouded in secrecy is still mildly creepy.
