Symzonia; Voyage of Discovery

In order to prove the existence of a hollow Earth first proposed by Captain John Cleve Symmes Captain Seaborn organized an expedition to the center of the Earth. Though ostensibly going on a sealing voyage in the South Seas Seaborn and his crew make landfall in the South Pole after Seaborn successfully sees off a mutiny. Upon debarking Seaborn and his crew find an enormous animal resembling a mammoth and a large skeleton resembling a whale. Combined with the lush land Seaborn thinks that he has made a discovery of incredible importance only to be exceeded by the possibility of discovering the center of the Earth.
