The red warrior whom he had put to flight turned in the entrance to the palace, and, seeing Carthoris' intent, snatched a rifle from those that he and his fellows had left leaning against the wall as they had rushed out with drawn swords to prevent the theft of their prisoner.
Few red men are good shots, for the sword is their chosen weapon; so now as the Dusarian drew bead upon the rising flier, and touched the button upon his rifle's stock, it was more to chance than proficiency that he owed the partial success of his aim.
The projectile grazed the flier's side, the opaque coating breaking sufficiently to permit daylight to strike in upon the powder phial within the bullet's nose.
There was a sharp explosion. Carthoris felt his craft reel drunkenly beneath him, and the engine stopped.
The momentum the air boat had gained carried her on over the city toward the sea-bottom beyond.
The red warrior in the plaza fired several more shots, none of which scored. Then a lofty minaret shut the drifting quarry from his view.
In the distance before him Carthoris could see the green warrior bearing Thuvia of Ptarth away upon his mighty thoat. The direction of his flight was toward the north-west of Aaanthor, where lay a mountainous country little known to red men.
The Heliumite now gave his attention to his injured craft.
A close examination revealed the face that one of the buoyancy tanks had been punctured, but the engine itself was uninjured.
A splinter from the projectile had damaged one of the control levers beyond the possibility of repair outside a machine shop; but after considerable tinkering, Carthoris was able to propel his wounded flier at low speed, a rate which could not approach the rapid gait of the thoat, whose eight long, powerful legs carried it over the ochre vegetation of the dead sea-bottom at terrific speed.
The Prince of Helium chafed and fretted at the slowness of his pursuit, yet he was thankful that the damage was no worse, for now he could at least move more rapidly than on foot.
But even this meagre satisfaction was soon to be denied him, for presently the flier commenced to sag toward the port and by the bow. The damage to the buoyancy tanks had evidently been more grievous than he had at first believed.
All the balance of that long day Carthoris crawled erratically through the still air, the bow of the flier sinking lower and lower, and the list to port becoming more and more alarming, until at last, near dark, he was floating almost bowdown, his harness buckled to a heavy deck ring to keep him from being precipitated to the ground below.
His forward movement was now confined to a slow drifting with the gentle breeze that blew out of the south-east, and when this died down with the setting of the sun, he let the flier sink gently to the mossy carpet beneath.
Far before him loomed the mountains toward which the green man had been fleeing when last he had seen him, and with dogged resolution the son of John Carter, endowed with the indomitable will of his mighty sire, took up the pursuit on foot.
All that night he forged ahead until, with the dawning of a new day, he entered the low foothills that guard the approach to the fastness of the mountains of Torquas.
