Journey to the Earth's Interior, The

1913 Gardner, a hollow-earth proponent, presents you with his unique scientific hypothesis explaining the formation of hollow planets. In this most fascinating book, you get vital facts of geography, exploration and astronomy that explains theories of shape and constitution of the earth held so far. On the basis of these theories he presents his own claim which fits his scientific investigations and does not conflict with any other facts in the world but unites them with an intelligible manner. This is a great edition for those interested in flying saucer books and who are familiar with the works of Dr. Raymond Bernard.
