Chapter 20: In the Atmosphere Factory

For two days I waited there for Kantos Kan, but as he did not come I started off on foot in a northwesterly direction toward a point where he had told me lay the nearest waterway. My only food consisted of vegetable milk from the plants which gave so bounteously of this priceless fluid.

Through two long weeks I wandered, stumbling through the nights guided only by the stars and hiding during the days behind some protruding rock or among the occasional hills I traversed. Several times I was attacked by wild beasts; strange, uncouth monstrosities that leaped upon me in the dark, so that I had ever to grasp my long-sword in my hand that I might be ready for them. Usually my strange, newly acquired telepathic power warned me in ample time, but once I was down with vicious fangs at my jugular and a hairy face pressed close to mine before I knew that I was even threatened.

What manner of thing was upon me I did not know, but that it was large and heavy and many-legged I could feel. My hands were at its throat before the fangs had a chance to bury themselves in my neck, and slowly I forced the hairy face from me and closed my fingers, vise-like, upon its windpipe.

Without sound we lay there, the beast exerting every effort to reach me with those awful fangs, and I straining to maintain my grip and choke the life from it as I kept it from my throat. Slowly my arms gave to the unequal struggle, and inch by inch the burning eyes and gleaming tusks of my antagonist crept toward me, until, as the hairy face touched mine again, I realized that all was over. And then a living mass of destruction sprang from the surrounding darkness full upon the creature that held me pinioned to the ground. The two rolled growling upon the moss, tearing and rending one another in a frightful manner, but it was soon over and my preserver stood with lowered head above the throat of the dead thing which would have killed me.

The nearer moon, hurtling suddenly above the horizon and lighting up the Barsoomian scene, showed me that my preserver was Woola, but from whence he had come, or how found me, I was at a loss to know. That I was glad of his companionship it is needless to say, but my pleasure at seeing him was tempered by anxiety as to the reason of his leaving Dejah Thoris. Only her death I felt sure, could account for his absence from her, so faithful I knew him to be to my commands.

By the light of the now brilliant moons I saw that he was but a shadow of his former self, and as he turned from my caress and commenced greedily to devour the dead carcass at my feet I realized that the poor fellow was more than half starved. I, myself, was in but little better plight but I could not bring myself to eat the uncooked flesh and I had no means of making a fire. When Woola had finished his meal I again took up my weary and seemingly endless wandering in quest of the elusive waterway.

At daybreak of the fifteenth day of my search I was overjoyed to see the high trees that denoted the object of my search. About noon I dragged myself wearily to the portals of a huge building which covered perhaps four square miles and towered two hundred feet in the air. It showed no aperture in the mighty walls other than the tiny door at which I sank exhausted, nor was there any sign of life about it.

I could find no bell or other method of making my presence known to the inmates of the place, unless a small round role in the wall near the door was for that purpose. It was of about the bigness of a lead pencil and thinking that it might be in the nature of a speaking tube I put my mouth to it and was about to call into it when a voice issued from it asking me whom I might be, where from, and the nature of my errand.

I explained that I had escaped from the Warhoons and was dying of starvation and exhaustion.

"You wear the metal of a green warrior and are followed by a calot, yet you are of the figure of a red man. In color you are neither green nor red. In the name of the ninth day, what manner of creature are you?"

"I am a friend of the red men of Barsoom and I am starving. In the name of humanity open to us," I replied.

Presently the door commenced to recede before me until it had sunk into the wall fifty feet, then it stopped and slid easily to the left, exposing a short, narrow corridor of concrete, at the further end of which was another door, similar in every respect to the one I had just passed. No one was in sight, yet immediately we passed the first door it slid gently into place behind us and receded rapidly to its original position in the front wall of the building. As the door had slipped aside I had noted its great thickness, fully twenty feet, and as it reached its place once more after closing behind us, great cylinders of steel had dropped from the ceiling behind it and fitted their lower ends into apertures countersunk in the floor.

A second and third door receded before me and slipped to one side as the first, before I reached a large inner chamber where I found food and drink set out upon a great stone table. A voice directed me to satisfy my hunger and to feed my calot, and while I was thus engaged my invisible host put me through a severe and searching cross-examination.

"Your statements are most remarkable," said the voice, on concluding its questioning, "but you are evidently speaking the truth, and it is equally evident that you are not of Barsoom. I can tell that by the conformation of your brain and the strange location of your internal organs and the shape and size of your heart."

"Can you see through me?" I exclaimed.

"Yes, I can see all but your thoughts, and were you a Barsoomian I could read those."

Then a door opened at the far side of the chamber and a strange, dried up, little mummy of a man came toward me. He wore but a single article of clothing or adornment, a small collar of gold from which depended upon his chest a great ornament as large as a dinner plate set solid with huge diamonds, except for the exact center which was occupied by a strange stone, an inch in diameter, that scintillated nine different and distinct rays; the seven colors of our earthly prism and two beautiful rays which, to me, were new and nameless. I cannot describe them any more than you could describe red to a blind man. I only know that they were beautiful in the extreme.

The old man sat and talked with me for hours, and the strangest part of our intercourse was that I could read his every thought while he could not fathom an iota from my mind unless I spoke.

[Illustration: The old man sat and talked with me for hours.]

I did not apprise him of my ability to sense his mental operations, and thus I learned a great deal which proved of immense value to me later and which I would never have known had he suspected my strange power, for the Martians have such perfect control of their mental machinery that they are able to direct their thoughts with absolute precision.

The building in which I found myself contained the machinery which produces that artificial atmosphere which sustains life on Mars. The secret of the entire process hinges on the use of the ninth ray, one of the beautiful scintillations which I had noted emanating from the great stone in my host's diadem.

This ray is separated from the other rays of the sun by means of finely adjusted instruments placed upon the roof of the huge building, three-quarters of which is used for reservoirs in which the ninth ray is stored. This product is then treated electrically, or rather certain proportions of refined electric vibrations are incorporated with it, and the result is then pumped to the five principal air centers of the planet where, as it is released, contact with the ether of space transforms it into atmosphere.

There is always sufficient reserve of the ninth ray stored in the great building to maintain the present Martian atmosphere for a thousand years, and the only fear, as my new friend told me, was that some accident might befall the pumping apparatus.

He led me to an inner chamber where I beheld a battery of twenty radium pumps any one of which was equal to the task of furnishing all Mars with the atmosphere compound. For eight hundred years, he told me, he had watched these pumps which are used alternately a day each at a stretch, or a little over twenty-four and one-half Earth hours. He has one assistant who divides the watch with him. Half a Martian year, about three hundred and forty-four of our days, each of these men spend alone in this huge, isolated plant.

Every red Martian is taught during earliest childhood the principles of the manufacture of atmosphere, but only two at one time ever hold the secret of ingress to the great building, which, built as it is with walls a hundred and fifty feet thick, is absolutely unassailable, even the roof being guarded from assault by air craft by a glass covering five feet thick.

The only fear they entertain of attack is from the green Martians or some demented red man, as all Barsoomians realize that the very existence of every form of life of Mars is dependent upon the uninterrupted working of this plant.
