"Where is the key, Sola? Let me have it."

"Sarkoja wears it, John Carter," she answered.

I turned without further word and sought out Tars Tarkas, to whom I vehemently objected to the unnecessary humiliations and cruelties, as they seemed to my lover's eyes, that were being heaped upon Dejah Thoris.

"John Carter," he answered, "if ever you and Dejah Thoris escape the Tharks it will be upon this journey. We know that you will not go without her. You have shown yourself a mighty fighter, and we do not wish to manacle you, so we hold you both in the easiest way that will yet ensure security. I have spoken."

I saw the strength of his reasoning at a flash, and knew that it were futile to appeal from his decision, but I asked that the key be taken from Sarkoja and that she be directed to leave the prisoner alone in future.

"This much, Tars Tarkas, you may do for me in return for the friendship that, I must confess, I feel for you."

"Friendship?" he replied. "There is no such thing, John Carter; but have your will. I shall direct that Sarkoja cease to annoy the girl, and I myself will take the custody of the key."

"Unless you wish me to assume the responsibility," I said, smiling.

He looked at me long and earnestly before he spoke.

"Were you to give me your word that neither you nor Dejah Thoris would attempt to escape until after we have safely reached the court of Tal Hajus you might have the key and throw the chains into the river Iss."

"It were better that you held the key, Tars Tarkas," I replied

He smiled, and said no more, but that night as we were making camp I saw him unfasten Dejah Thoris' fetters himself.

With all his cruel ferocity and coldness there was an undercurrent of something in Tars Tarkas which he seemed ever battling to subdue. Could it be a vestige of some human instinct come back from an ancient forbear to haunt him with the horror of his people's ways!

As I was approaching Dejah Thoris' chariot I passed Sarkoja, and the black, venomous look she accorded me was the sweetest balm I had felt for many hours. Lord, how she hated me! It bristled from her so palpably that one might almost have cut it with a sword.

A few moments later I saw her deep in conversation with a warrior named Zad; a big, hulking, powerful brute, but one who had never made a kill among his own chieftains, and a second name only with the metal of some chieftain. It was this custom which entitled me to the names of either of the chieftains I had killed; in fact, some of the warriors addressed me as Dotar Sojat, a combination of the surnames of the two warrior chieftains whose metal I had taken, or, in other words, whom I had slain in fair fight.

As Sarkoja talked with Zad he cast occasional glances in my direction, while she seemed to be urging him very strongly to some action. I paid little attention to it at the time, but the next day I had good reason to recall the circumstances, and at the same time gain a slight insight into the depths of Sarkoja's hatred and the lengths to which she was capable of going to wreak her horrid vengeance on me.

Dejah Thoris would have none of me again on this evening, and though I spoke her name she neither replied, nor conceded by so much as the flutter of an eyelid that she realized my existence. In my extremity I did what most other lovers would have done; I sought word from her through an intimate. In this instance it was Sola whom I intercepted in another part of camp.

"What is the matter with Dejah Thoris?" I blurted out at her. "Why will she not speak to me?"

Sola seemed puzzled herself, as though such strange actions on the part of two humans were quite beyond her, as indeed they were, poor child.

"She says you have angered her, and that is all she will say, except that she is the daughter of a jed and the granddaughter of a jeddak and she has been humiliated by a creature who could not polish the teeth of her grandmother's sorak."

I pondered over this report for some time, finally asking, "What might a sorak be, Sola?"

"A little animal about as big as my hand, which the red Martian women keep to play with," explained Sola.

Not fit to polish the teeth of her grandmother's cat! I must rank pretty low in the consideration of Dejah Thoris, I thought; but I could not help laughing at the strange figure of speech, so homely and in this respect so earthly. It made me homesick, for it sounded very much like "not fit to polish her shoes." And then commenced a train of thought quite new to me. I began to wonder what my people at home were doing. I had not seen them for years. There was a family of Carters in Virginia who claimed close relationship with me; I was supposed to be a great uncle, or something of the kind equally foolish. I could pass anywhere for twenty-five to thirty years of age, and to be a great uncle always seemed the height of incongruity, for my thoughts and feelings were those of a boy. There was two little kiddies in the Carter family whom I had loved and who had thought there was no one on Earth like Uncle Jack; I could see them just as plainly, as I stood there under the moonlit skies of Barsoom, and I longed for them as I had never longed for any mortals before. By nature a wanderer, I had never known the true meaning of the word home, but the great hall of the Carters had always stood for all that the word did mean to me, and now my heart turned toward it from the cold and unfriendly peoples I had been thrown amongst. For did not even Dejah Thoris despise me! I was a low creature, so low in fact that I was not even fit to polish the teeth of her grandmother's cat; and then my saving sense of humor came to my rescue, and laughing I turned into my silks and furs and slept upon the moon-haunted ground the sleep of a tired and healthy fighting man.

We broke camp the next day at an early hour and marched with only a single halt until just before dark. Two incidents broke the tediousness of the march. About noon we espied far to our right what was evidently an incubator, and Lorquas Ptomel directed Tars Tarkas to investigate it. The latter took a dozen warriors, including myself, and we raced across the velvety carpeting of moss to the little enclosure.

It was indeed an incubator, but the eggs were very small in comparison with those I had seen hatching in ours at the time of my arrival on Mars.

Tars Tarkas dismounted and examined the enclosure minutely, finally announcing that it belonged to the green men of Warhoon and that the cement was scarcely dry where it had been walled up.

"They cannot be a day's march ahead of us," he exclaimed, the light of battle leaping to his fierce face.

The work at the incubator was short indeed. The warriors tore open the entrance and a couple of them, crawling in, soon demolished all the eggs with their short-swords. Then remounting we dashed back to join the cavalcade. During the ride I took occasion to ask Tars Tarkas if these Warhoons whose eggs we had destroyed were a smaller people than his Tharks.

"I noticed that their eggs were so much smaller than those I saw hatching in your incubator," I added.

He explained that the eggs had just been placed there; but, like all green Martian eggs, they would grow during the five-year period of incubation until they obtained the size of those I had seen hatching on the day of my arrival on Barsoom. This was indeed an interesting piece of information, for it had always seemed remarkable to me that the green Martian women, large as they were, could bring forth such enormous eggs as I had seen the four-foot infants emerging from. As a matter of fact, the new-laid egg is but little larger than an ordinary goose egg, and as it does not commence to grow until subjected to the light of the sun the chieftains have little difficulty in transporting several hundreds of them at one time from the storage vaults to the incubators.
