Baron Trump's Marvelous Underground Journey by Ingersoll Lockwood was published in 1893. The novel recounts the adventures of the German boy Wilhelm Heinrich Sebastian von Troomp, who goes by the name "Baron Trump", and his dog Bulger, as they discover fantastic underground civilizations, offend the natives, escape from their involvements, and repeat this pattern until arriving back home at Castle Trump. The novel was part of a trend in American children's literature that responded to the demand for fantastic adventure stories created by Lewis Carroll's Alice's Adventures in Wonderland (1865).
