This book purports to be a manuscript dictated by a strange being named I-Am-The-Man to a man named Llewyllyn Drury. Drury's adventure culminates in a trek through a cave in Kentucky into the core of the earth. It blends passages on the nature of physical phenomena, such as gravity and volcanoes, with spiritualist speculation and adventure-story elements (like traversing a landscape of giant mushrooms).

1896 with many illustrations by J. Augustus Knapp. with added chapters from the 11th edition. the strange history of a mysterious being and the account of a remarkable journey into the Hollow Earth as communicated to Llewellyn Druruy. Fiction? None b.

Beginning with the Hollow Earth/Hollow Planets theory, science can now begin to discover a whole new way of looking at the Universe. NASA may not be able to see life on any of the planets of our Solar System, yet if they are hollow, a whole new frontier of space exploration will open up. If the so-called gaseous planets are in reality hollow, they all could have solid surfaces, including the Sun! The signature of a star is its output of radio waves, electromagnetic radiation and atomic particles -- a solar wind. NASA has discovered auroras emitting from Earth, Jupiter, Saturn, Neptune and Uranus. Since none of these planets, including even Earth, receive enough energy from the Sun to light up their auroras, the Hollow Earth theory provides an alternative answer: The solar wind causing the auroras of all the planets comes from their Inner Suns emanating through polar openings. Earthquakes on Earth cause the earth to vibrate like a bell, which is hollow. Apollo missions to the Moon discovered that the Moon rings like a bell when hit by a large meteorite, and images of the surface of the Sun show quakes on the surface of the Sun that cause tsunamis to go out from the epicenter passing over mountain features on the surface. Perhaps the stories of explorers going into the interior of the Earth, the Sun and other planets and finding human populations living there are based on a truth that God creates planets to be inhabited, not so much on their exteriors, but on their interiors. The Lost Ten Tribes are rumored to have found an entrance into the hollow of the Earth in the North and explorers who have been there through the North Polar Opening report that the people there have built a fantastic civilization with flying saucer technology, long lives, perfect health and an economy of abundance. Maybe our astronomers have been looking in the wrong place for life on other worlds. Perhaps worlds are not built by the Creator primarily to be inhabited on their exteriors, but on their interiors where the people can be shielded from meteor and asteroid hits, impossibly cold and hot climates, dust storms, tornados and hurricane winds. The people of Tibet believe in an underworld they call Agartha. The Indians of America believe their ancestors emerged from within the Earth. Even the Lost Books of the Bible relate how our first parents Adam and Eve emerged from "Mother Earth" after being evicted by God from the Garden of Eden. Come with us, and let's explore the next frontier -- the hollow earth and hollow planets where we can learn where we came from, why we are here on this planet and what is soon to come.
