In Scotland the Degree is also worked in Craft Lodges and I'm told this is also the case with some Scots Lodges in Australia that remain under Scottish jurisdiction. An attempt was made in Queensland some years ago to get UGLQ to restore the old situation, it was rightly rejected as the Degree is administered outside Craft jurisdiction.
So what is The Mark? Basically it is an extension of the F.C. Degree, which is theoretically supposed to qualify those Advanced to it to preside over a lodge of Operative Masons (just let some MMM try bossing folks on building sites around.
As usual rituals vary from State to State and those of the Mark Lodges differ from what is worked in a Royal Arch Chapter. Everything starts and ends the same though, candidates receive the same messages and secrets, and visiting either system poses no problems.
We go back to KST where the candidate represents a FC seeking advancement to the Degree. In the course of the Ceremony he is given a personal Mark, just as illiterate masons of old received so there work could be identified. (Many old buildings in Europe still have stones bearing such marks). He usually also receives a Mark Penny a traditional token of the Grade. This portion of the Ceremony ends with him being made a Mark Man, he then takes part in a dramatic playlet in which he represents a FC with great ambition who finds all his hopes destroyed. The Ceremony is most dramatic in places but all works out well and in the end the Mark Man is finally created a Mark Master Mason.
The Degree contains many useful messages among which I'd include..Do not let ambition alone motivate your development, let humility guide you as well. Do not rigidly apply yourself to set ideas and concepts, look at innovations intelligently. Don't reject that which is outside your limited perspective without close examination. And most important of all..Even when everything has crashed around you and all your hopes have come to naught if you have Faith Blessing can rise from Disaster. (This message was of great help to me two years ago and in my case it proved to be correct.). There is much more that can be learned within the Degree, suffice it to say it is worthwhile no matter where or how you take it.
Regalia consists of a characteristic apron and a jewel. In HRA Chapters MM regalia is worn by the candidate until he takes the HRA.
