parties are lowered to the ground from the battleships.
I swung this hook cautiously to the roof several times before it finally found lodgment; gently I pulled on it to strengthen its hold, but whether it would bear the weight of my body I did not know. It might be barely caught upon the very outer verge of the roof, so that as my body swung out at the end of the strap it would slip off and launch me to the pavement a thousand feet below.
An instant I hesitated, and then, releasing my grasp upon the supporting ornament, I swung out into space at the end of the strap. Far below me lay the brilliantly lighted streets, the hard pavements, and death. There was a little jerk at the top of the supporting eaves, and a nasty slipping, grating sound which turned me cold with apprehension; then the hook caught and I was safe.
Clambering quickly aloft I grasped the edge of the eaves and drew myself to the surface of the roof above. As I gained my feet I was confronted by the sentry on duty, into the muzzle of whose revolver I found myself looking.
"Who are you and whence came you?" he cried.
"I am an air scout, friend, and very near a dead one, for just by the merest chance I escaped falling to the avenue below," I replied.
"But how came you upon the roof, man? No one has landed or come up from the building for the past hour. Quick, explain yourself, or I call the guard."
"Look you here, sentry, and you shall see how I came and how close a shave I had to not coming at all," I answered, turning toward the edge of the roof, where, twenty feet below, at the end of my strap, hung all my weapons.
The fellow, acting on impulse of curiosity, stepped to my side and to his undoing, for as he leaned to peer over the eaves I grasped him by his throat and his pistol arm and threw him heavily to the roof. The weapon dropped from his grasp, and my fingers choked off his attempted cry for assistance. I gagged and bound him and then hung him over the edge of the roof as I myself had hung a few moments before. I knew it would be morning before he would be discovered, and I needed all the time that I could gain.
Donning my trappings and weapons I hastened to the sheds, and soon had out both my machine and Kantos Kan's. Making his fast behind mine I started my engine, and skimming over the edge of the roof I dove down into the streets of the city far below the plane usually occupied by the air patrol. In less than a minute I was settling safely upon the roof of our apartment beside the astonished Kantos Kan.
I lost no time in explanation, but plunged immediately into a discussion of our plans for the immediate future. It was decided that I was to try to make Helium while Kantos Kan was to enter the palace and dispatch Sab Than. If successful he was then to follow me. He set my compass for me, a clever little device which will remain steadfastly fixed upon any given point on the surface of Barsoom, and bidding each other farewell we rose together and sped in the direction of the palace which lay in the route which I must take to reach Helium.
As we neared the high tower a patrol shot down from above, throwing its piercing searchlight full upon my craft, and a voice roared out a command to halt, following with a shot as I paid no attention to his hail. Kantos Kan dropped quickly into the darkness, while I rose steadily and at terrific speed raced through the Martian sky followed by a dozen of the air-scout craft which had joined the pursuit, and later by a swift cruiser carrying a hundred men and a battery of rapid-fire guns. By twisting and turning my little machine, now rising and now falling, I managed to elude their search-lights most of the time, but I was also losing ground by these tactics, and so I decided to hazard everything on a straight-away course and leave the result to fate and the speed of my machine.
Kantos Kan had shown me a trick of gearing, which is known only to the navy of Helium, that greatly increased the speed of our machines, so that I felt sure I could distance my pursuers if I could dodge their projectiles for a few moments.
As I sped through the air the screeching of the bullets around me convinced me that only by a miracle could I escape, but the die was cast, and throwing on full speed I raced a straight course toward Helium. Gradually I left my pursuers further and further behind, and I was just congratulating myself on my lucky escape, when a well-directed shot from the cruiser exploded at the prow of my little craft. The concussion nearly capsized her, and with a sickening plunge she hurtled downward through the dark night.
How far I fell before I regained control of the plane I do not know, but I must have been very close to the ground when I started to rise again, as I plainly heard the squealing of animals below me. Rising again I scanned the heavens for my pursuers, and finally making out their lights far behind me, saw that they were landing, evidently in search of me.
Not until their lights were no longer discernible did I venture to flash my little lamp upon my compass, and then I found to my consternation that a fragment of the projectile had utterly destroyed my only guide, as well as my speedometer. It was true I could follow the stars in the general direction of Helium, but without knowing the exact location of the city or the speed at which I was traveling my chances for finding it were slim.
Helium lies a thousand miles southwest of Zodanga, and with my compass intact I should have made the trip, barring accidents, in between four and five hours. As it turned out, however, morning found me speeding over a vast expanse of dead sea bottom after nearly six hours of continuous flight at high speed. Presently a great city showed below me, but it was not Helium, as that alone of all Barsoomian metropolises consists in two immense circular walled cities about seventy-five miles apart and would have been easily distinguishable from the altitude at which I was flying.
Believing that I had come too far to the north and west, I turned back in a southeasterly direction, passing during the forenoon several other large cities, but none resembling the description which Kantos Kan had given me of Helium. In addition to the twin-city formation of Helium, another distinguishing feature is the two immense towers, one of vivid scarlet rising nearly a mile into the air from the center of one of the cities, while the other, of bright yellow and of the same height, marks her sister.
CHAPTER XXIV
TARS TARKAS FINDS A FRIEND
About noon I passed low over a great dead city of ancient Mars, and as I skimmed out across the plain beyond I came full upon several thousand green warriors engaged in a terrific battle. Scarcely had I seen them than a volley of shots was directed at me, and with the almost unfailing accuracy of their aim my little craft was instantly a ruined wreck, sinking erratically to the ground.
I fell almost directly in the center of the fierce combat, among warriors who had not seen my approach so busily were they engaged in life and death struggles. The men were fighting on foot with long-swords, while an occasional shot from a sharpshooter on the outskirts of the conflict would bring down a warrior who might for an instant separate himself from the entangled mass.
As my machine sank among them I realized that it was fight or die, with good chances of dying in any event, and so I struck the ground with drawn long-sword ready to defend myself as I could.
I fell beside a huge monster who was engaged with three antagonists, and as I glanced at his fierce face, filled with the light of battle, I recognized Tars Tarkas the Thark. He did not see me, as I was a trifle behind him, and just then the three warriors opposing him, and whom I recognized as Warhoons, charged simultaneously. The mighty fellow made quick work of one of them, but in stepping back for another thrust he fell over a dead body behind him and was down and at the mercy of his foes in an instant. Quick as lightning they were upon him, and Tars Tarkas would have been gathered to his fathers in short order had I not sprung before his prostrate form and engaged his adversaries. I had accounted for one of them when the mighty Thark
