On the 6th of August,1842,with quite a number of his brethren,he [Joseph Smith] crossed the Mississippi river to the town of Montrose,to be present at the installation of the Masonic Lodge of the Rising Sun. A block schoolhouse had been prepared with shade in front,under which was a barrel of ice water,Judge James Adams was the highest Masonic authority in the state of Illinois,and had been sent there to organize this lodge. He and Hyrum Smith,being high Masons,went into the house to perform some ceremonies which the others were not en***led to witness. These,including Joseph Smith,remained under the bowery. Joseph, as he was tasting the cold water,warned the brethren not to be too free with it. With the tumbler still in his hand he prophesied that the saints would yet go to the Rocky Mountains;and,said he,this water tastes much like that of the crystal streams that are running from the snow-capped mountains. We will let Mr. Call describe this prophetic scene:'I had before seen him in a vision,and now saw while he was talking his countenance change to white;not the deadly white of a bloodless face,but a living,brilliant white. He seemed absorbed in gazing at something at a great distance, and said:'I am gazing upon the valleys of those mountains.'This was followed by a vivid description of the scenery of these mountains,as I have since become acquainted with it. Pointing to Shadrach Roundy and others,he said:'There are some men here who shall do a great work in that land.' Pointing to me,he said: 'There is Anson,he shall go and shall ***ist in building up cities from one end of the country to the other;and you, rather extending the idea to all those he had spoken of, shall perform as great a work as has been done by man,so that the nations of the earth shall be astonished,and many of them will be gathered in that land and ***ist in building cities and temples,and Israel shall be made to rejoice.
