Wilford Woodruff dedicates the Salt Lake temple, forty years after its cornerstone-laying. It is the largest LDS temple ever built, with 253,105 square feet of floor space. Joseph F. Smith "sobbed & wept like a child" as he gives his talk that day. Some see halos of light around first counselor George Q. Cannon and around Apostles Lorenzo Snow, John W. Taylor, and Heber J. Grant. Not everyone present sees these manifestations, and future apostle James E. Talmage notes: "There were no strange or bewildering manifestations of 'supernatural' agencies during the service: but the power of God was there, and the entire assembly felt it."
