"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." "You fight in platinum and diamonds?" asked Tara, indicating his gorgeous trappings with a quizzical smile. Gahan laughed. "We are a vain people," he admitted, good-naturedly, "and it is possible that we place too much value on personal appearances. We vie with one another in the splendor of our accoutrements when trapped for the observance of the lighter duties of life, though when we take the field our leather is the plainest I ever have seen worn by fighting men of Barsoom. We pride ourselves, too, upon our physical beauty, and especially upon the beauty of our women. May I dare to say, Tara of Helium, that I am hoping for the day when you will visit Gathol that my people may see one who is really beautiful?" "The women of Helium are taught to frown with displeasure upon the tongue of the flatterer," rejoined the girl, but Gahan, Jed of Gathol, observed that she smiled as she said it. A bugle sounded, clear and sweet, above the laughter and the talk. "The Dance of Barsoom!" exclaimed the young warrior. "I claim you for it, Tara of Helium."
