Susan in the Highlands it has taken a lot longer to dispense with secrecy at every level mainly as the Highlands practiced a type of freemasonry totally different to that which was practiced through the rest of Scotland.
Their freemasonry was jacobite freemasonry and as many lodges even now my own included date from 1739 just a few years prior to the 45 rebellion, they have been used to carrying this over all these years even although jacobite freemasonry doesn't exist any longer or has become dissolved into other degree,s or fraternities. It was very dangerous indeed to be a freemason in the Highlands in the years post 45 rebellion.
I remember books like "darkness visable" and others stemming from the 60s/70's that went a long way in exposing what went on within freemasonry and to be honest many were very close but always lacked the connection between ritual and text. The only things a mason is not permitted to talk about are those signs,words and grips with which to know a mason by but thats it, so Lugg is right the only secrets freemasonry has are these.
