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.
