rtment among the sleeping Torquasians. Not a man of them moved until Carthoris had completed more than half of the short though dangerous journey. Then a fellow directly in his path turned restlessly upon his sleeping silks and furs. The Heliumite paused above him, one of the short-swords in readiness should the warrior awaken. For what seemed an eternity to the young prince the green man continued to move uneasily upon his couch, then, as though actuated by springs, he leaped to his feet and faced the red man. Instantly Carthoris struck, but not before a savage grunt escaped the other`s lips. In an instant the room was in turmoil. Warriors leaped to their feet, grasping their weapons as they rose, and shouting to one another for an explanation of the disturbance. To Carthoris all within the room was plainly visible in the dim light reflected from without, for the further moon stood directly at zenith; but to the eyes of the newly-awakened green men objects as yet had not taken on familiar forms-they but saw vaguely the figures of warriors moving about their apartment. Now one stumbled against the corpse of him whom Carthoris had slain. The fellow stooped and his hand came in contact with the cleft skull. He saw about him the giant figures of other green men, and so he jumped to the only conclusion that was open to him. "The Thurds!" he cried. "The Thurds are upon us! Rise, warriors of Torquas, and drive home your swords within the hearts of Torquas` ancient enemies!" Instantly the green men began to fall upon one another with naked swords. Their savage lust of battle was aroused. To fight, to kill, to die with cold steel buried in their vitals! Ah, that to them was Nirvana. Carthoris was quick to guess their error and take advantage of it. He knew that in the pleasure of killing they might fight on long after they had discovered their mistake, unless their attention was distracted by sight of the real cause of the altercation, and so he lost no time in continuing across the room to the doorway upon the opposite side, which opened into the inner court, where the savage thoats were squealing and fighting among themselves. Once here he had no easy task before him. To catch and mount one of these habitually rageful and intractable beasts was no child`s play under the best of conditions; but now, when silence and time were such important considerations, it might well have seemed quite hopeless to a less resourceful and optimistic man than the son of the great warlord. From his father he had learned much concerning the traits of these mighty beasts, and from Tars Tarkas, also, when he had visited that great green jeddak among his horde at Thark. So now he centred upon the work in hand all that he had ever learned about them from others and from his own experience, for he, too, had ridden and handled them many times. The temper of the thoats of Torquas appeared even shorter than their vicious cousins among the Tharks and Warhoons, and for a time it seemed unlikely that he should escape a savage charge on the part of a couple of old bulls that circled, squealing, about him; but at last he managed to get close enough to one of them to touch the beast. With the feel of his hand upon the sleek hide the creature quieted, and in answer to the telepathic command of the red man sank to its knees. In a moment Carthoris was upon its back, guiding it toward the great gate that leads from the courtyard through a large building at one end into an avenue beyond. The other bull, still squealing and enraged, followed after his fellow. There was no bridle upon either, for these strange creatures are controlled entirely by suggestion-when they are controlled at all. Even in the hands of the giant green men bridle reins would be hopelessly futile against the mad savagery and mastodonic strength of the thoat, and so they are guided by that strange telepathic power with which the men of Mars have learned to communicate in a crude way with the lower orders of their planet. With difficulty Carthoris urged the two beasts to the gate, where, leaning down, he raised the latch. Then the thoat that he was riding placed his great shoulder to the skeel-wood planking, pushed through, and a moment later the man and the two beasts were swinging silently down the avenue to the edge of the plaza, where Kar Komak hid. Here Carthoris found considerable difficulty in subduing the second thoat, and as Kar Komak had never before ridden one of the beasts, it seemed a most hopeless job; but at last the bowman managed to scramble to the sleek back, and again the two beasts fled softly down the moss-grown avenues toward the open sea bottom beyond the city. All that night and the following day and the second night they rode toward the north-east. No indication of pursuit developed, and at dawn of the second day Carthoris saw in the distance the waving ribbon of great trees that marked one of the long Barsoomian water-ways. Immediately they abandoned their thoats and approached the cultivated district on foot. Carthoris also discarded the metal from his harness, or such of it as might serve to identify him as a Heliumite, or of royal blood, for he did not know to what nation belonged this waterway, and upon Mars it is always well to assume every man and nation your enemy until you have learned the contrary. It was mid-forenoon when the two at last entered one of the roads that cut through the cultivated districts at regular intervals, joining the arid wastes on either side with the great, white, central highway that follows through the centre from end to end of the far-reaching, threadlike farm lands. The high wall surrounding the fields served as a protection against surprise by raiding green hordes, as well as keeping the savage banths and other carnivora from the domestic animals and the human beings upon the farms. Carthoris stopped before the first gate he came to, pounding for admission. The young man who answered his summons greeted the two hospitably, though he looked with considerable wonder upon the white skin and auburn hair of the bowman. After he had listened for a moment to a partial narration of their escape from the Torquasians, he invited them within, took them to his house and bade the servants there prepare food for them. As they waited in the low-ceiled, pleasant livingroom of the farmhouse until the meal should be ready, Carthoris drew his host into conversation that he might learn his nationality, and thus the nation under whose dominion lay the waterway where circumstance had placed him. "I am Hal Vas," said the young man, "son of Vas Kor, of Dusar, a noble in the retinue of Astok, Prince of Dusar. At present I am Dwar of the Road for this district." Carthoris was very glad that he had not disclosed his identity, for though he had no idea of anything that had transpired since he had left Helium, or that Astok was at the bottom of all his misfortunes, he well knew that the Dusarian had no love for him, and that he could hope for no assistance within the dominions of Dusar. "And who are you?" asked Hal Vas. "By your appearance I take you for a fighting man, but I see no insignia upon your harness. Can it be that you are a panthan?" Now, these wandering soldiers of fortune are common upon Barsoom, where most men love to fight. They sell their services wherever war exists, and in the occasional brief intervals when there is no organized warfare between the red nations, they join one of the numerous expeditions that are constantly being dispatched against the green men in protection of the waterways that traverse the wilder portions of the globe. When their service is over they discard the metal of the nation they have been serving until they shall have found a new master. In the intervals they wear no insignia, their war-worn harness and grim weapons being sufficient to attest their calling. The suggestion was a happy one, and Carthoris embraced the chance it afforded to account satisfactorily for himself. There was, however, a single drawback. In times of war such panthans as happened to be within the domain of a belligerent nation were compelled to don the insignia of that nation and fight with her warriors. As far as Carthoris knew Dusar was not at war with any other nation, but there was never any telling when one red nation would be flying at the throat of a neighbour, even though the great and powerful alliance at the head of which was his father, John Carter, had managed to maintain a long peace upon the greater portion of Barsoom. A pleasant smile lighted Hal Vas` face as Carthoris admitted his vocation. "It is well," exclaimed the young man, "that you chanced to come hither, for here you will find the means of obtaining service in short order. My father, Vas Kor, is even now with me, having come hither to recruit a force for the new war against Helium."
