Gathol: This is an exceeding wealthy city state located in the NW hemisphere thought to be the oldest inhabited city upon Barsoom.
"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 (diamond) 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 . . .
"Our natural barriers, while they have doubtless saved us from defeat on countless occasions, have not by any means rendered us immune from attack," he explained, "for so great is the wealth of Gathol's diamond treasury that there yet may be found those who will risk almost certain defeat in an effort to loot our unconquered city; so thus we find occasional practice in the exercise of arms; but there is more to Gathol than the mountain city. My country extends from Polodona (Equator) north ten karads and from the tenth karad west of Horz to the twentieth west, including thus a million square haads, the greater proportion of which is fine grazing land where run our great herds of thoats and zitidars.
"Surrounded as we are by predatory enemies our herdsmen must indeed be warriors or we should have no herds, and you may be assured they get plenty of fighting. Then there is our constant need of workers in the mines. The Gatholians consider themselves a race of warriors and as such prefer not to labor in the mines. The law is, however, that each male Gatholian shall give an hour a day in labor to the government. That is practically the only tax that is levied upon them. They prefer however, to furnish a substitute to perform this labor, and as our own people will not hire out for labor in the mines it has been necessary to obtain slaves, and I do not need to tell you that slaves are not won without fighting. We sell these slaves in the public market, the proceeds going, half and half, to the government and the warriors who bring them in. The purchasers are credited with the amount of labor performed by their particular slaves. At the end of a year a good slave will have performed the labor tax of his master for six years, and if slaves are plentiful he is freed and permitted to return to his own people. . .
