_The Assembly Hall_: In the south-west corner of {206} Temple Block stands the Assembly Hall, a substantial structure designed for congregations of smaller size than those requiring the great Tabernacle auditorium. During the summer of 1877 the Old Tabernacle, about which so many pleasant memories had clustered, was removed to make room for the new building. The Assembly Hall was begun in the year named, and, though meetings were held in the unfinished structure, it was not until 1882 that the building was ready for dedication. The edifice is one hundred and twenty by sixty-eight feet, including the extreme recesses. The walls are of granite from the quarries in Cottonwood canyon. _General Service Plant_: All the buildings at present occupying Temple Block, together with many others on adjoining squares, are supplied with steam, hot-water, and electric current for light, heat, and power, from an independent plant situated near the middle of the city square immediately west from Temple Block. From this plant great subterranean tunnels lead to the several buildings connected therewith. The main tunnel is six feet six inches in height, by five feet six inches in width; through this run all pipes for steam and water, ammonia pipes for cooling purposes, and, in addition, a full equipment of electric conductors. The diverging branch-tunnels are each six feet six inches by four feet. The buildings supplied from this plant with electric light, heat, and power, and with steam and hot water, are the following: 1. All the buildings on Temple Block, comprising the great Temple and its accessories, viz., the Annex, the conservatory, the gate house or porter's cottage, the Tabernacle, the Assembly Hall, and the Bureau of Information. {207} 2. All the buildings belonging to the Latter-day Saints' University, comprising the Business College, Barratt Hall, the Brigham Young Memorial Building, and the Lion House. 3. The Bishop's Building, and the old Tithing Office or Bishop's Store House, now used for work in connection with the Latter-day Saints' University. 4. The Deseret Gymnasium. 5. The offices of the First Presidency of the Church, together with the official residence of the President, known as the Bee Hive House. These buildings are situated at a distance of two and one-half city squares from the main plant. 6. The large and famous hostelry, the Hotel Utah. 7. The Deseret News Building and the Deseret News Annex. 8. The Vermont Building. 9. The Sharon Building, and several other smaller structures. The entire length of the tunnel system is over fourteen hundred feet, and the tunnels are constructed of reinforced concrete with walls six inches thick. From this brief and partial description, it will be seen that the equipment of buildings occupying or adjoining Temple Block, is commensurate and adequate. FOOTNOTES
