The Marine Mysteries of Pencroff

On long winter evenings, comfortably settled in front of the fireplace, five friends, brave inhabitants of the Mysterious Island, engaged in endless and fascinating conversations. About what? About everything in the world! The incredibly interesting memories of Bonaventure Pencroff—a seasoned... sailor and fearless traveler—were the favorites among them. His stories were not quite ordinary. Each contained a geographical mystery. How are atolls formed? Is it possible to catch fish on land? Where is the sea in which one cannot drown? Are there ice floes at the equator? Where do giant waves come from?.. Try to answer all the tricky questions of the tireless explorer of the marine expanses along with the inhabitants of the Granite Palace.
