In a very recent issue of Science and Invention Dr. Hartman tells of the amazing discoveries he has made in the Mediterranean, off the coast of Sicily, when he went below the sea in his newly constructed steel diving bell, which was designed to withstand a pressure of 2,500 pounds per square inch or a sub-sea depth of about 5,000 feet. During his latest venture below the sea level, Dr. Hartman discovered a prehistoric city—perhaps the Lost Atlantis. Why, then, should it be impossible to assume that there might be cities—even vast cities—submerged miles below the Pacific, for instance, and made habitable? But whatever else might be said, "The Green Girl" is a scientifiction classic that will rank with the best that have ever been published. Though it is a wild, exciting, fantastic tale, it is exceedingly plausible withal. - Summary from Original Gutenberg text
