The domed roof of the Tabernacle has attracted the attention of every one who has seen even a picture of the city. In some of its architectural features the building is unique. It covers an area of 250 x 180 feet and has a seating capacity of eight thousand. The colossal roof-arch springs from wall to wall without a supporting pillar. Within is the monster organ, which for size and scope is approached by few instruments in the world. It was constructed in early days from native material by Utah artisans, and has been regarded as a marvel of mechanical and artistic achievement. The story of Salt Lake City is really a chapter of "Mormon" history. To-day its population would probably show a majority of non-Mormons, but the Church of Jesus Christ of Latter-day Saints is the dominant sect in city and State. Numerous other churches have established themselves; many of them have reared imposing sanctuaries and are active in the promulgation of their doctrines. [Illustration CITY AND COUNTY BUILDING, SALT LAKE CITY.] Non-Mormon citizens have been as ready and earnest in their efforts to build up and sustain the city of their choice as have their Latter-day Saint fellows; and the present beauty, strength, and vitality of the inter-mountain metropolis are largely due to non-Mormon, or "Gentile," enterprise and energy. The "Gentiles" have ever been the more prominent in mining undertakings, and the large and paying mines of to-day are mostly theirs. Salt Lake City does not belong to the "Mormons"; it is the possession of its citizens without regard to religious profession or political preference. [Illustration LION AND BEE-HIVE HOUSES.] Since man and nature combined their energies in this once desert spot, the favored situation, the many natural advantages have yearly grown more apparent. Located at the very base of the Wasatch, bounded in part by a spur of this majestic range, the city possesses a wealth of mountain scenery beyond description. The valley floor is part of the bed of an inland sea of Quaternary age; and the benches and hills constituting the choicest residence portions are the terraces of this ancient lake, or the deltas of the prehistoric streams whose mouths were at the present cañon openings. Capitol Hill and the Northeast Bench are parts of the great delta constructed by City Creek in Lake Bonneville. Of this Pleistocene water body, approximately equal to Lake Huron in extent, the present Salt Lake, in spite of its common appellation "great," is but a diminutive fragment.
