"And perhaps too because of the great distance that separates Helium and Gathol, as well as the comparative insignificance of my little free city, which might easily be lost in one corner of mighty Helium," added Gahan. "But what we lack in power we make up in pride," he continued, laughing. "We believe ours the oldest inhabited city upon Barsoom. It is one of the few that has retained its freedom, and this despite the fact that its ancient diamond mines are the richest known and, unlike practically all the other fields, are today apparently as inexhaustible as ever." "Tell me of Gathol," urged the girl. "The very thought fills me with interest," nor was it likely that the handsome face of the young jed detracted anything from the glamour of far Gathol. Nor did Gahan seem displeased with the excuse for further monopolizing the society of his fair companion. His eyes seemed chained to her exquisite features, from which they moved no further than to a rounded breast, part hid beneath its jeweled covering, a naked shoulder or the symmetry of a perfect arm, resplendent in bracelets of barbaric magnificence. "Your ancient history has doubtless told you that Gathol was built upon an island in Throxeus, mightiest of the five oceans of old Barsoom. As the ocean receded Gathol crept down the sides of the mountain, the summit of which was the island upon which she had been built, until today she covers the slopes from summit to base, while the bowels of the great hill are honeycombed with the galleries of her mines. Entirely surrounding us is a great salt marsh, which protects us from invasion by land, while the rugged and ofttimes vertical topography of our mountain renders the landing of hostile airships a precarious undertaking." "That, and your brave warriors?" suggested the girl. Gahan smiled. "We do not speak of that except to enemies," he said, "and then with tongues of steel rather than of flesh." "But what practice in the art of war has a people which nature has thus protected from attack?" asked Tara of Helium, who had liked the young jed's answer to her previous question, but yet in whose mind persisted a vague conviction of the possible effeminacy of her companion, induced, doubtless, by the magnificence of his trappings and weapons which carried a suggestion of splendid show rather than grim utility.
