“Tarzan at the Earth’s Core” Called from his home in the African jungle to great adventure, Tarzan of the Apes summons his Waziri spearman and joins the Jason Gridley expedition to seek the Arctic opening in the Earth's surface that leads to the inner world of Pellucidar. There, where time does not exist, where neither Tarzan’s jungle nor the charts of scientists are of any use as guides, they face the problem of rescuing an American adventurer who's held captive by the bloodthirsty Korsars.” It was written by Edgar Rice Burroughs (1875 – 1950) and illustrated by J. Allen St. John. This edition was published by Grosset & Dunlap in 1930.
