"Of course I'm all right," said Pan Dan Chee; "but you? How badly are you hurt?"

"I am not hurt at all. You kept the brute so busy it didn't have a chance to maul me."

"Thanks be to my ancestors!" exclaimed Pan Dan Chee fervently. Suddenly he turned on her. "Now," he said, "I have fought for you. What is your answer?"

Llana of Gathol shrugged her pretty shoulders. "You have not fought a man," she said, "-just a little banth."

Well, I never did understand women.

In my former life on Earth I spent more time in the saddle than I did on foot, and since I have been here on the Planet of Barsoom I have spent much time in the saddle or on the swift fliers of the Navy of Helium; so naturally I did not look forward with any great amount of pleasure to walking fifteen hundred miles.

However, it had to be done; and when a thing has to be done the best plan is to get at it, stick to it, and get it over with as quickly as possible.

Gathol is southwest of Horz; but, having no compass and no landmarks, I went, as I discovered later, a little too far to the west. Had I not done so we might have been saved some very harrowing experiences. Although, if my past life is any criterion, we would have found plenty of other adventures.

We had covered some two thousand five hundred haads of the four thousand we had to travel, or at least as nearly as I could compute it, with a minimum of untoward incidents. On two occasions we had been attacked by banths but had managed to kill them before they could harm us; and we had been attacked by a band of wild calots, but fortunately we had met no human beings-of all the creatures of Barsoom the most dangerous. For here, outside of your own country or the countries of your allies, every man is your enemy and bent upon destroying you; nor is it strange upon a dying world the natural resources of which have dwindled almost to the vanishing point and even air and water are only barely sufficient to meet the requirements of the present population.

The vast stretches of dead sea bottom, covered with its ocher vegetation, which we traversed were broken only occasionally by low hills. Here in shaded ravines we sometimes found edible roots and tubers. But for the most part we subsisted upon the milk-like sap of the mantalia bush, which grows on the dead sea bottom, though in no great profusion.

We had tried to keep track of the days, and it was on the thirty-seventh day that we encountered really serious trouble. It was the fourth zode, which is roughly about one P.M. Earth time, that we saw in the distance and to our left what I instantly recognized as a caravan of green Martians.

As no fate can be worse than falling into the hands of these cruel monsters, we hurried on in the hope of crossing their path before we were discovered. We took advantage of what cover the sea bottom afforded us, which was very little; oftentimes compelling us to worm our way along on our bellies, an art which I had learned from the Apaches of Arizona. I was in the lead, when I came upon a human skeleton. It was crumbling to dust, an indication that it must have lain there for many years, for so low is the humidity on Mars that disintegration of bony structures is extremely slow. Within fifty yards I came upon another skeleton and after that we saw many of them. It was a gruesome sight, and what it portended I could not guess. At first I thought that perhaps a battle had once been fought here, but when I saw that some of these skeletons were fresh and well preserved and that others had already started to disintegrate I realized that these men had died many years apart.

At last I felt that we had crossed the line of march of the caravan and that as soon as we had found a hiding place we would be comparatively safe, and just then I came to the edge of a yawning chasm.

Except for the Grand Canyon of the Colorado, I had never seen anything like it.

It was a great rift valley that appeared to be about ten miles wide and perhaps two miles deep, extending for miles in either direction.

There were outcroppings of rock at the rim of the rift, and behind these we hid.

Scattered about us were more human skeletons than we had seen before. Perhaps they were a warning; but at least they could not harm us, and so we turned our attention to the approaching caravan, which had now changed its direction a little and was coming straight toward us. Hoping against hope that they would again change their direction and pass us, we lay there watching them.

When I had been first miraculously transported to Mars I had been captured by a horde of green men, and I had lived with them for a long time; so that I learned to know their customs well. Therefore, I was quite positive that this caravan was making the quinquennial pilgrimage of the horde to its hidden incubator.

Each adult Martian female brings forth about thirteen eggs each year; and those which reach the correct size, weight, and specific gravity are hidden in the recesses of some subterranean vault where the temperature is too low for incubation. Every year these eggs are carefully examined by a counsel of twenty chieftains, and all but about one hundred of the most perfect are destroyed out of each yearly supply. At the end of five years about five hundred almost perfect eggs have been chosen from the thousands brought forth. These are then placed in the almost air-tight incubators to be hatched by the sun's rays after a period of another five years.

All but about one per cent of the eggs hatch, and these are left behind when the horde departs from the incubator. If these eggs hatch, the fate of those abandoned little Martians is unknown. They are not wanted, as their offspring might inherit and transmit the tendency to prolonged incubation and thus upset the system which has been maintained for ages and which permits the adult Martians to figure the proper time for return to the incubator almost to an hour.

The incubators are built in remote fastnesses where there is little or no likelihood of their being discovered by other tribes. The result of such a catastrophe would mean no children in the community for another five years.

The green Martians' caravan is a gorgeous and barbaric thing to see. In this one were some two hundred and fifty enormous three-wheeled chariots drawn by huge mastodonian animals known as zitidars, any one of which from their appearance might easily have drawn the entire train when fully loaded.

The chariots themselves were large, commodious and gorgeously decorated; in each was seated a female Martian loaded with ornaments of metal, with jewels and silks and furs; and upon the back of each of the zitidars a young Martian driver was perched on top of gorgeous trappings.

At the head of the caravan rode some two hundred warriors, five abreast; and a like number brought up the rear. About twenty-five or thirty out-riders flanked the chariots on either side.

The mounts of the warriors defy description in earthly words. They towered ten feet at the shoulder, had four legs on either side, a broad flat tail, larger at the tip than at the root, which they held straight out behind while running; a gaping mouth which splits the head from the snout to the long, massive neck.

Like their huge masters, they are entirely devoid of hair, but are a dark slate color and are exceedingly smooth and glossy. Their bellies are white and their legs shaded from the slate of the shoulders and hips to a vivid yellow at the feet. The feet themselves are heavily padded and nailless. Like the zitidars they wear neither bit nor bridle, but are guided entirely by telepathic means.

As we watched this truly magnificent and impressive cortege, it changed direction again; and I breathed a sigh of relief as I saw that they were going to pass us. Evidently, from the backs of their lofty mounts, they had seen the rift and were now moving parallel with it.
