Ebook: Lost Continents & the Hollow Earth

From the back cover: "Lost Continents & the Hollow Earth is Childress' thorough examination of the early hollow earth stories of Richard Shaver, and the fascination that fringe fantasy subjects such as lost continents, UFOs, and the hollow earth have had for the American public. Shaver's rare 1948 book I Remember Lemuria is reprinted in its entirety, and the book is packed with illustrations from Ray Palmer's Amazing Stories issues of the 1940s. Palmer and Shaver told of tunnels running through the earth -- tunnels inhabited by the Deros and Teros, humanoids from an ancient spacefaring race that had inhabited the earth, eventually going undergroupnd, hundreds of thousands of years ago. Childress discusses famous hollow earth books and delves deep into whatever reality may be behind the stories of tunnels underground. He tells of 'Operation High Jump' to Antarctica in 1947, polar explorer Admiral Byrd's bizarre statements about a land beyond the pole, tunnel systems in South America and Tibet, the underground world of Agharta, and the belief of UFOs coming from the South Pole. From tunneling machines to underground flying saucer bases, this is a rollicking ride to a world where science-fiction collides head-on with science-fact!"

While Shaver's work is available, the material here by Childress is no longer available insofar as I can discover. I've uploaded the individual page scans in a zip archive, plus a PDF made from those scans.
