Should the Mormons continue unmolested--I think they will complete this rather remarkable edifice. (Picture of the) Great Salt Lake. Great Salt Lake.--The great salt dead sea of the desert. I know of no greater curiosity than this inland sea of thick brine. It is eighty miles wide--and one hundred and thirty miles long. Solid masses of salt are daily washed ashore in immense heaps--and the Mormon in want of salt has only to go to the shore of this lake and fill his cart. Only--the salt for table use has to be subjected to a boiling process. These are facts--susceptible of the clearest possible proof. They tell one story about this lake--however--that I have my doubts about. They say a Mormon farmer drove forty head of cattle in there once--and they came out firstrate pickled beef.-- * * * * * * * * * * * * * * * I sincerely hope you will excuse my absence--I am a man short--and have to work the moon myself. (Here Artemus would leave the rostrum for a few moments, and pretend to be engaged behind. The picture was painted for a night-scene, and the effect intended to be produced was that of the moon rising over the lake and rippling on the waters. It was produced in the usual dioramic way, by making the track of the moon transparent and throwing the moon on from the bull's eye of the lantern. When Artemus went behind, the moon would become nervous and flickering, dancing up and down in the most inartistic and undecided manner. The result was that, coupled with the lecturer's oddly expressed apology, the "moon" became one of the best laughed-at parts of the entertainment.) I shall be most happy to pay a good salary to any respectable boy of good parentage and education who is a good moonist. (Picture of) The Endowment House. In this building the Mormon is initiated into the mysteries of the faith. Strange stories are told of the proceedings which are held in this building--but I have no possible means of knowing how true they may be. Salt Lake City is fifty-five miles behind us--and this is Echo Canyon--in reaching which we are supposed to have crossed the summit of the Wahsatch Mountains. These ochre-colored bluffs--formed of conglomerate sandstone--and full of fossils--signal the entrance to the Canyon. At its base lies Weber Station. Echo Canyon is about twenty-five miles long. It is really the sublimest thing between the Missouri and the Sierra Nevada. The red wall to the left develops farther up the Canyon into pyramids--buttresses--and castles--honey-combed and fretted in nature's own massive magnificence of architecture. In 1856--Echo Canyon was the place selected by Brigham Young for the Mormon General Wells to fortify and make impregnable against the advance of the American army--led by General Albert Sidney Johnson. It was to have been the Thermopylae of Mormondom--but it wasn't general Wells was to have done Leonidas--but he didn't.
