This is the Aniversary of the Arival of the Pioneers into Salt Lake Valley. I Carried President Brigham Young in my Carriag through Emigration Canyon into the valley of the Great Salt Lake 38 years ago this day. And this is the day Appointed By the Presidet of the United States, The General of the Armey, & Gov Murry to send An Armey unto Salt Lake to Destroy the Mormons if they Put the flag at half mast. And yet in the Providence of God President Clearland was under the necessity of Commanding all the People of the United States to place the flag at half mast on that particular day and Gov Murry Commanded the People of Salt [Lake City] to do the same for Gen [Ulysses] Grant was Dead [had died the day before] and the Lord had prepared him as a scape Goat to bear of the Sins of the Mormons.
