[James E. Talmage]
It is a day long to be remembered. With ceremonies deeply impressive, the capstone of that mighty edifice [Salt Lake Temple] was laid. The act of laying the stone was performed by President Woodruff, through the agency of electricity—the stone being suspended above its place, a catch was released, and the topmost stone of the Temple fell into position [...] and when the shout 'Hosanna!' went forth, its reverberations were deafening.
