“It’s all right, this business of living in a palace,” said Bob, one day. “Just the same I for one can never accustom myself to living in a tomb. And that’s what this seems like, with its old stone walls and courts and secret passages, and what not.” With this opinion, Jack and Frank were in hearty agreement. Likewise Roy Stone, who after repairing his airplane had flown it to the plain outside Athensi where it rested now with just sufficient fuel to carry him out of the desert when the time came to depart. Departure, however, he kept putting off from time to time at the insistence of his friends. Ali and his Arabs continued to stay with Mr. Hampton, the wounded members of the party now fully restored to health. In the Great Library of Athensi, the biggest building in extent within the Inner City, were found as the revolutionists had predicted many thousands of manuscripts or papyrus rolls written in the ancient mother tongue of Atlantis of which Athensian was a corruption. Few of the young nobles among the revolutionists ever had been within the library before, as the ancients of the Oligarchs had guarded it jealously. They were even more eager than Mr. Hampton to browse, if that word can properly be employed in this connection. But when they came to examining the rolls, they found that it was only with difficulty they could here and there decipher a word. However, the similarity of languages was such that in time the mother tongue could be learned and the treasured knowledge of this most ancient of libraries in the oldest living city on earth, could be unlocked and given to the world. To the task of learning the language and of putting the library in order, Captain Amanassar who had been elected President of the new republican government, assigned Amonasis, Amrath and two dozen assistants, comprising the best educated of the young revolutionists. Eagerly, they began their task. At length, with a story that later was to astound not only the scientific world but all civilization, Mr. Hampton, finding his advice no longer was required, decided to depart. They had been absent from home five months. Bob and Frank were overdue for their Senior year at Yale. Mr. Hampton was to be the unofficial representative of the Athensian government to the United States, and was to pave the way for official representatives to be sent to the various world capitals by making public his account of events. In addition, he was to interest capitalists in developing the resources of the country, and in building a railroad linking up Athensi with the Cape-to-Cairo Railroad. He promised to return the following year, estimating it would require that length of time at least to perform his various commissions. On his return, the boys planned to accompany him and to build a great radio station at Athensi, which would put the mountain people in touch with all the world.
