The main room is divided into apartments for the ceremonies of the endowment. Beginning from the door at the West end is an all[e]y about 5 feet wide extending to about 3 feet beyond the first Beam of[f] the arch. On each side of the Alley is a small room partitioned off where the saints receive the first part of the ceremony or where the man is created and a help mate given to him. From these rooms to the third partition in the Arch is planted the garden, which is nicely decorated and set off with shrubs and trees in pots and Boxes to represent the Garden of Eden. In this apartment is also an altar. Here the man and woman are placed and commandments given to them a charge at the Alter and the first and second tokens of the Aaronic Priesthood. They are then thrust out into a room which is dark being the one on the North side between the fourth and fifth division of the arch which represents the telestial kingdom or the world. Opposite to this is another apartment of the same size representing the terrestrial kingdom and between these two is an alley about 4 feet wide. In the telestial kingdom, after the man has proved himself faithful he receives the first signs and tokens of the Melchizedek priesthood and an additional charge. Here also he vouches for the conduct of his companion. They are then left to prove themselves faithful, after which they are admitted into the terrestrial kingdom, where at the alter they receive an additional charge and the second token of the Melchizedek Priesthood and also the key word on the five points of fellowship.
There are words given with every token and the new name is given in the preparation room when they receive their washing and annointing.
After received all the tokens and words and signs they are led to the vail where they give each to Eloheem through the vail and are then admitted into the Celestial Room.
