MORMONS. Great dissatisfaction exists among the members of the Mormon Church. The reign of Brigham Young is characterized not only by spiritual domination, but by a tyranny quite in-supportable, consuming the substance of the peo-ple by taxation, the proceeds of which go to other objects than the support of the Church, and many hesitate not to upbraid him, and other prominent members, for their open and undisguised indul-gence in vice and crime. Many families are leav-ing Salt Lake, and will take up their residence in California.
