The existence of natural ice-caves at depths varying from 50 to 200 feet below the surface of the earth, unconnected with glaciers or snow mountains, and in latitudes and at altitudes where ice could not under ordinary circumstances be supposed to exist, has attracted some attention. In addition to the description of this natural phenomena, the author has interspersed his incidents of travel. He has also given accounts of similar caves in different parts of the world.
