southern regions of the United States.
it consists of a piece of red flannel shaped like a human finger and stuffed with coal dust and dirt, and contains
a silver dime.
After being charged with magickal power by an incantation invoking the presence and help of the old gods, a jack Amulet can be worn or
carried to prevent a traveler from losing his or her way.
