It was then that I got my first good look at the man whose cause I had espoused; and I got a shock, too. This was no red man, but a white man if I have ever seen one. His skin was bronzed by exposure to the sun, as is mine; and that had at first deceived me. But now I saw that there was nothing red-Martian about him.

His harness, his weapons, everything about him differed from any that I had seen on Mars.

He wore a headdress, which is quite unusual upon Barsoom. It consisted of a leather band that ran around the head just above his brows, with another leather band crossing his from right to left and a second from front to rear. These bands were highly ornamented with carving and set with jewels and precious metals. To the center of the band that crossed his forehead was affixed a flat piece of gold in the shape of a spearhead with the point up. This, also, was beautifully carved and bore a strange device inlaid in red and black.

Confined by this headdress was a shock of blond hair-a most amazing thing to see upon Mars. At first I jumped to the conclusion that he must be a thern from the far south-polar land; but that thought I discarded at once when I realized that the hair was his own. The therns are entirely bald and wear great yellow wigs.

I also saw that my companion was strangely handsome. I might say beautiful were it not for the effeminateness which the word connotes, and there was nothing effeminate about the way this man fought or the mighty oaths that he swore when he spoke at all to an adversary. We fighting men are not given to much talk, but when you feel your blade cleave a skull in twain or drive through the heart of a foeman, then sometimes a great oath is wrenched from your lips.

But I had little time then to appraise my companion, for the remaining three were at us again in a moment. I fought that day, I suppose, as I have always fought; but each time it seems to me that I have never fought so well as upon that particular occasion. I do not take great credit for my fighting ability, for it seems to me that my sword is inspired. No man could think as quickly as my point moves, always to the right spot at the right time, as though anticipating the next move of an adversary. It weaves a net of steel about me that few blades have ever pierced. It fills the foeman's eyes with amazement and his mind with doubt and his heart with fear. I imagine that much of my success has been due to the psychological effect of my swordsmanship upon my adversaries.

Simultaneously my companion and I each struck down an antagonist, and then the remaining warrior turned to flee. "Do not let him escape!" cried my comrade-in-arms, and leaped in pursuit, at the same time calling loudly for help, something he had not done when close to death before the points of six swords. But whom did he expect to answer his appeal in this dead and deserted city? Why did he call for help when the last of his antagonists was in full flight? I was puzzled; but having enlisted myself in this strange adventure, I felt that I should see it through; and so I set off in pursuit of the fleeing green man.

He crossed the courtyard where we had been engaged and made for a great archway that opened out into a broad avenue. I was close behind him, having outstripped both him and the strange warrior. When I came into the avenue I saw the green man leap to the back of one of six thoats waiting there, and at the same time I saw at least a hundred warriors pouring from a nearby building. They were yellow-haired white men, garbed like my erstwhile fighting companion, who now joined in the pursuit of the green man. They were armed with bows and arrows; and they sent a volley of missiles after the escaping quarry, whom they could never hope to overtake, and who was soon out of range of their weapons.

The spirit of adventure is so strong within me that I often yield to its demands in spite of the dictates of my better judgment. This matter was no affair of mine. I had already done all, and even more than could have been expected of me; yet I leaped to the back of one of the remaining thoats and took off in pursuit of the green warrior.

There are two species of thoat on Mars: the small, comparatively docile breed used by the red Martians as saddle animals and, to a lesser extent, as beasts of burden on the farms that border the great irrigation canals; and then there are the huge, vicious, unruly beasts that the green warriors use exclusively as steeds of war.

These creatures tower fully ten feet at the shoulder. They have four legs on either side and a broad, flat tail, larger at the tip than at the root, that they hold straight out behind while running. Their gaping mouths split their heads from their snouts to their long, massive necks. Their bodies, the upper portion of which is a dark slate color and exceedingly smooth and glossy, are entirely devoid of hair. Their bellies are white, and their legs shade gradually from the slate color of their bodies to a vivid yellow at the feet, which are heavily padded and nailless.

The thoat of the green man has the most abominable disposition of any creature I have ever seen, not even the green men themselves excepted. They are constantly fighting among themselves, and woe betide the rider who loses control of his terrible mount; yet, paradoxical as it may appear, they are ridden without bridle or bit; and are controlled solely by telepathic means, which, fortunately for me, I learned many ago while I was prisoner of Lorquas Ptomel, jed of the Tharks, a green Martian horde.

The beast to whose back I had vaulted was a vicious devil, and he took violent exception to me and probably to my odor. He tried to buck me off; and, failing that, reached back with his huge, gaping jaws in an effort to seize me.

There is, I might mention, an auxiliary method of control when these ugly beasts become recalcitrant; and I adopted it in this instance, notwithstanding the fact that I had won grudging approval from the fierce green Tharks by controlling thoats through patience and kindness. I had time for neither now, as my quarry was racing along the broad avenue that led to the ancient quays of Horz and the vast dead sea bottoms beyond; so I laid heavily upon the head and snout of the beast with the flat of my longsword until I had beaten it into subjection; then it obeyed my telepathic commands, and set out at great speed in pursuit.

It was a very swift thoat, one of the swiftest that I had ever bestrode; and, in addition, it carried much less weight than the beast we sought to overtake; so we closed up rapidly on the escaping green man.

At the very edge of the plateau upon which the old city was built we caught up with him, and there he stopped and wheeled his mount and prepared to give battle. It was then that I began to appreciate the marvelous intelligence of my mount. Almost without direction from me he maneuvered into the correct positions to give me an advantage in this savage duel, and when at last I had achieved a sudden advantage which had almost unseated my rival, my thoat rushed like a mad devil upon the thoat of the green warrior tearing at its throat with his mighty jaws while he tried to beat it to its knees with the weight of his savage assault.

It was then that I gave the coup de grace to my beaten and bloody adversary; and, leaving him where he had fallen, rode back to receive the plaudits and the thanks of my newfound friends.

They were waiting for me, a hundred of them, in what had probably once been a public market place in the ancient city of Horz. They were not smiling. They looked sad. As I dismounted, they crowded around me.

"Did the green man escape?" demanded one whose ornaments and metal proclaimed him a leader.

"No," I replied; "he is dead."

A great sigh of relief arose from a hundred throats. Just why they should feel such relief that a single green man had been killed I did not then understand.
