Many are found who say: “Leave Mormonism to itself, and it will die.” The Pacific Railroad alone, they think, will kill it. Those Americans who know Utah best are not of this opinion. Mormonism is no superstition of the past. There is huge vitality in the polygamic church. Emerson once spoke to me of Unitarianism, Buddhism, and Mormonism as three religions which, right or wrong, are full of force. “The Mormons only need to be persecuted,” said Elder Frederick to me, “to become as powerful as the Mohammedans.” It is, indeed, more than doubtful whether polygamy can endure side by side with American monogamy--it is certain that Mormon priestly power and Mormon mysteries cannot in the long run withstand the presence of a large Gentile population; but, if Mormon titles to land are respected, and if great mineral wealth is not found to exist in Utah, Mormonism will not be exposed to any much larger Gentile intrusion than it has to cope with now. Settlers who can go to California or to Colorado “pares” will hardly fix themselves in the Utah desert. The Mexican table-lands will be annexed before Gentile immigrants seriously trouble Brigham. Gold and New England are the most dreaded foes of Mormondom. Nothing can save polygamy if lodes and placers such as those of all the surrounding States are found in Utah; nothing can save it if the New Englanders determine to put it down. Were Congress to enforce the Homestead laws in Utah, and provide for the presence of an overwhelming Gentile population, polygamy would not only die of itself, but drag Mormonism down in its fall. Brigham knows more completely than we can the necessity of isolation. He would not be likely to await the blow which increased Gentile immigration would deal his power. If New England decides to act, the table-lands of Mexico will see played once more the sad comedy of Utah. Again the Mormons will march into Mexican territory, again to wake some day, and find it American. Theirs, however, will once more be the pride of having proved the pioneers of that English civilization which is destined to overspread the temperate world. The treaty of Guadalupe Hidalgo annexed Utah to the United States, but Brigham Young annexed it to Anglo-Saxondom. CHAPTER XVIII. NAMELESS ALPS. At the post-office, in Main Street, I gave Mr. Dixon a few last messages for home--he one to me for some Egyptian friends; and, with a shake and a wave, we parted, to meet in London after between us completing the circuit of the globe.
