“The people will tell thee”, Don Fum keeps advising readers of his fifteenth-century manuscript. Baron Trump (full name, Wilhelm Heinrich Sebastian von Troomp) uses the manuscript as a guide to lead him to the World Within a World. And the people do tell Baron Trump the vicinity of the Giants’ Well, gateway to the secret world, high up in Russia’s Northern Ural Mountains. He climbs the foothills, and with the assistance of Yuliana, an old woman, “half witch perhaps,” who knows an herb for every ailment, he reaches the Giants’ Well. (Background: Baron Trump Journeys to Russia, Ersjdamoo’s Blog, October 13, 2017.)
Says Yuliana to Baron Trump: “Thou art not what thou seemst. I never saw the like of thee before.”  Is Yuliana perceiving a time traveler, a visitor to 1893 from the future? John G. Trump, paternal uncle of Donald Trump, reviewed and analyzed the papers of Nikola Tesla when Tesla died in a New York City hotel in 1943. 
Baron Trump and his faithful dog Bulger pass through the Quarries of the Demons in the Northern Urals. At the Giants’ Well they descend down, down into the depths. They then pass through the Funnel of Polyphemus (named after the giant son of Poseidon and Thoosa in Greek mythology) and enter the World Within a World. 
In this secret world, Baron Trump and Bulger eventually arrive at a silver city, home of the Soodopsies, also called the Formifolk. The Formifolk lead Trump and Bulger through a beautiful passage, the walls and floors of which are made of pure silver. 
Silver! Ingersoll Lockwood’s book, Baron Trump’s Marvelous Underground Journey, published in 1893, echoes the populist silver sentiments of the time. It was the time of the Silver Tongued Orator of the Platte River, William Jennings Bryan, who, in 1896, delivered his famous “Cross of Gold” speech at the Democrat Convention in Chicago:
You shall not press down upon the brow of labor this crown of thorns; you shall not crucify mankind upon a cross of gold.
Also echoing the “Free Silver” sentiments were Fran Striker’s later Lone Ranger stories. The Ranger had inherited a silver mine from his father, who was from the “Free Silver” times. The Ranger calls his horse, “Silver,” and uses silver bullets. 
Arrayed against the forces of Free Silver were supporters of the gold standard. They “followed the yellow brick road,” like Dorothy and Toto in L. Frank Baum’s Wizard of Oz stories, which emerged around 1900. “Oz” is the abbreviation for Ounce. Dorothy and Toto followed the yellow brick road and where did it lead? To the “wizard”, who turned out to be not as he seemed.
