[Apostle Wilford Woodruff Journal]
This is the Anniversary of the Entrance of the Pioneers into this vally on the 24 day of July 1847, Being 27 years ago. The Inhabitants of this City have been laboring for several weeks to adorn the great Tabernacle to prepare a Great Jubilee of the Sabbath school Children of 4 Counties Salt Lake, Utah, & Davis & Webber. From 8,000 to 10,000 Children Assembled in the Tabernacle & the rest of the room was occupied by adults. It was judged that there were 14,000 people in the Tabernacle. Most of the time was occupied with songs & Music. Short speeches were made By President B Young G A Smith & G Q. Cannon. The whole Tabernacle was decorated with Evergreens & taking it altogether it was the grandest view & scene of my life. A day long to be remembered.
