This strange book expounds quite convincingly the theory that the earth is hollow. Interestingly, this book was published well after scientific experiments had proven quite conclusively that the idea was not valid. The discovery of the North pole four years earlier also challenged the author. This accomplishment dented the assertion made by author Marshall Gardner that the pole was the site of an entrance into the earth's depths.
