Tarzan watched the construction of the new dome with keenest interest, realizing that it was the only opportunity that he ever would have to see the interior of one of these remarkable, human hives, and as he was thus engaged Komodoflorensal and his friends hastened to initiate him into the mysteries of their language; and while he learned the language of his hosts he learned many other things of interest about them. The slaves, he discovered, were either prisoners of war or the descendants of prisoners of war. Some had been in bondage for so many generations that all trace of their origin had become lost and they considered themselves as much citizens of Trohanadalmakus, the city of King Adendrohahkis, as did any of the nobility. On the whole they were treated with kindness and were not overworked after the second generation. The recent prisoners and their children were, for the most part, included in the caste of unskilled labor from which the limit of human endurance was exacted. They were the miners, the quarriers and the builders and fully fifty percent of them were literally worked to death. With the second generation the education of the children commenced, those who showed aptitude for any of the skilled crafts being immediately transferred from the quarries to the domes, where they took up the relatively easy life of a prosperous and indulged middleclass. In another manner might an individual escape the quarries—by marriage, or rather by selection as they choose to call it, with a member of the ruling class. In a community where class consciousness was such a characteristic of the people and where caste was almost a fetish it was rather remarkable that such connections brought no odium upon the inferiors, but, on the contrary, automatically elevated the lesser to the caste of the higher contracting party.
“It is thus, Deliverer of the Son of Adendrohahkis,” explained Komodoflorensal, in reply to Tarzan’s inquiry relative to this rather peculiar exception to the rigid class distinctions the king’s son had so often impressed upon him: “Ages ago, during the reign of Klamataamorosal in the city of Trohanadalmakus, the warriors of Veltopishago, king of the city of Veltopismakus, marched upon our fair Trohanadalmakus and in the battle that ensued the troops of our ancestors were all but annihilated. Thousands of our men and women were carried away into slavery and all that saved us from being totally wiped out was the courageous defense that our own slaves waged for their masters. Klamataamorosal, from whom I am descended, fighting in the thick of the fray noted the greater stamina of the slaves; they were stronger than the warriors of either city and seemed not to tire at all, while the high caste nobility of the fighting clans, though highly courageous, became completely exhausted after a few minutes of fighting.
“After the battle was over Klamataamorosal called together all the chief officers of the city, or rather all who had not been killed or taken prisoner, and pointed out to them that the reason our city had been defeated was not so much because of the greater numbers of the forces of the king Veltopishago as to the fact that our own warriors were physical weaklings, and he asked them why this should be and what could be done to remedy so grievous a fault. The youngest man among them, wounded and weak from loss of blood, was the only one who could offer a reasonable explanation, or suggest a means of correcting the one obvious weakness of the city.
“He called their attention to the fact that of all the race of Minunians the people of the city of Trohanadalmakus were the most ancient and that for ages there had been no infusion of new blood, since they were not permitted to mate outside their own caste, while their slaves, recruited from all the cities of Minuni, had interbred, with the result that they had become strong and robust while their masters, through inbreeding, had grown correspondingly weaker.
“He exhorted Klamataamorosal to issue a decree elevating to the warrior class any slave that was chosen as mate by either a man or woman of that class, and further to obligate each and every warrior to select at least one mate from among their slaves. At first, of course, the objections to so iconoclastic a suggestion were loud and bitter; but Klamataamorosal was quick to sense the wisdom of the idea and not only did he issue the decree, but he was the first to espouse a slave woman, and what the king did all were anxious to do also.
“The very next generation showed the wisdom of the change and each succeeding generation has more than fulfilled the expectations of Klamataamorosal until now you see in the people of Trohanadalmakus the most powerful and warlike of the Minunians.
“Our ancient enemy, Veltopismakus, was the next city to adopt the new order, having learned of it through slaves taken in raids upon our own community, but they were several generations behind us. Now all the cities of Minuni wed their warriors with their slave women. And why not? Our slaves are all descended from the warrior class of other cities from which their ancestors were captured. We all are of the same race, we all have the same language and in all important respects the same customs.
“Time has made some slight changes in the manner of the selection of these new mates and now it is often customary to make war upon another city for the sole purpose of capturing their noblest born and most beautiful women.
“For us of the royal family it has been nothing less than salvation from extinction. Our ancestors were transmitting disease and insanity to their progeny. The new, pure, virile blood of the slaves has washed the taint from our veins and so altered has our point of view become that whereas, in the past, the child of a slave
