What is the inside of the Earth like; what mysteries does its mantle conceal? What will the sensitive feelers of superdeep holes encounter there—boiling liquid magma or superhard matter, unimaginably high temperatures or cold approa­ ching absolute zero? Science cannot as yet give the exact answers to these questions, though myriads of different hypotheses have been put forth. This book tells haw scientists are 'erreting out the secrets of the deeper zones of the Earth; its subject is the romance of the searches and tenacious investigations carried out by geologists who have devoted themselves to the study of the depths of our planet.
