Some day you must hunt up and read for yourselves a book entitled “Atlantis or the Antediluvian World.” Written by Ignatius Donnelly, it was published by Harper & Brothers in 1882. In it are collected Plato’s story of Atlantis and a wealth of evidences which go to prove, in the author’s opinion, that Atlantis did actually exist, that it was the home of the white race, the Semitic race and, perhaps, the Turanian, and that it was destroyed by a convulsion of Nature. Since Donnelly’s book, investigation has gone further. Savants uncovered near the southern edge of the Sahara Desert about the time of the outbreak of the Great War the ruins of two great cities of an unknown civilization, believed to have been seats of a migration from Atlantis. The war, however, halted their research, and up to a recent period the investigation had not been resumed. In one of these cities, people of an unknown white strain resided in a semi-savage state. I, therefore, have made them the background for this story, and that you will like it is the hope of THE AUTHOR. Emerson Hill, Staten Island, N. Y. 1923. CONTENTS I. Introduction. 3 II.
