AS I set my ship down in the sheltered cove along the shore of desolate Guadalupe a trifle over four hours after I left Tarzana, the little Mexican steamer I had chartered to transport my men, materials, and supplies from the mainland rode peacefully at anchor in the tiny harbor, while on the shore, waiting to welcome me, were grouped the laborers, mechanics, and assistants who had worked with such whole-hearted loyalty for long months in preparation for this day. Towering head and shoulders above the others loomed Jimmy Welsh, the only American among them.

I taxied in close to shore and moored the ship to a buoy, while the men launched a dory and rowed out to get me. I had been absent less than a week, most of which had been spent in Guaymas awaiting the expected letter from Tarzana, but so exuberantly did they greet me, one might have thought me a long-lost brother returned from the dead, so dreary and desolate and isolated is Guadalupe to those who must remain upon her lonely shores for even a brief interval between contacts with the mainland.

Perhaps the warmth of their greeting may have been enhanced by a desire to conceal their true feelings. We had been together constantly for months, warm friendships had sprung up between us, and tonight we were to separate with little likelihood that they and I should ever meet again. This was to be my last day on earth; after today I should be as dead to them as though three feet of earth covered my inanimate corpse.

It is possible that my own sentiments colored my interpretation of theirs, for I am frank to confess that I had been apprehending this last moment as the most difficult of the whole adventure. I have come in contact with the peoples of many countries, but I recall none with more lovable qualities than Mexicans who have not been contaminated by too close contact with the intolerance and commercialism of Americans. And then there was Jimmy Welsh. It was going to be like parting with a brother when I said good-bye to him. For months he had been begging to go with me; and I knew that he would continue to beg up to the last minute, but I could not risk a single life unnecessarily.

We all piled into the trucks that we had used to transport supplies and materials from the shore to the camp, which lay inland a few miles, and bumped over our makeshift road to the little table-land where the giant torpedo lay upon its mile long track.

"Everything is ready," said Jimmy. "We polished off the last details this morning. Every roller on the track has been inspected by at least a dozen men, we towed the old crate back and forth over the full length of the track three times with the truck, and then repacked all the rollers with grease. Three of us have checked over every item of equipment and supplies individually; we've done about everything but fire the rockets; and now we're ready to go--you are going to take me along, aren't you, Car?"

I shook my head. "Please don't, Jimmy," I begged; "I have a perfect right to gamble with my own life, but not with yours; so forget it. But I am going to do something for you," I added, "just as a token of my appreciation of the help you've given me and all that sort of rot. I'm going to give you my ship to remember me by."

He was grateful, of course, but still he could not hide his disappointment in not being allowed to accompany me, which was evidenced by an invidious comparison he drew between the ceiling of the Sikorsky and that of the old crate, as he had affectionately dubbed the great torpedolike rocket that was to bear me out into space in a few hours.

"A thirty-five million mile ceiling," he mourned dolefully; "think of it! Mars for a ceiling!"

"And may I hit the ceiling!" I exclaimed, fervently.

The laying of the track upon which the torpedo was to take off had been the subject of a year of calculation and consultation. The day of departure had been planned far ahead and the exact point at which Mars would rise above the eastern horizon on that night calculated, as well as the time; then it was necessary to make allowances for the rotation of the earth and the attraction of the nearer heavenly bodies. The track was then laid in accordance with these calculations. It was constructed with a very slight drop in the first three quarters of a mile and then rose gradually at an angle of two and one half degrees from horizontal.

A speed of four and one half miles per second at the take-off would be sufficient to neutralize gravity; to overcome it, I must attain a speed of 6.93 miles per second. To allow a sufficient factor of safety I had powered the torpedo to attain a speed of seven miles per second at the end of the runway, which I purposed stepping up to ten miles per second while passing through the earth's atmosphere. What my speed would be through space was problematical, but I based all my calculations on the theory that it would not deviate much from the speed at which I left the earth's atmosphere, until I came within the influence of the gravitational pull of Mars.

The exact instant at which to make the start had also caused me considerable anxiety. I had calculated it again and again, but there were so many factors to be taken into consideration that I had found it expedient to have my figures checked and rechecked by a well-known physicist and an equally prominent astronomer. Their deductions tallied perfectly with mine-- the torpedo must start upon its journey toward Mars some time before the red planet rose above the eastern horizon. The trajectory would be along a constantly flattening arc, influenced considerably at first by the earth's gravitational pull, which would decrease inversely as the square of the distance attained. As the torpedo left the earth's surface on a curved tangent, its departure must be so nicely timed that when it eventually escaped the pull of the earth its nose would be directed toward Mars.

On paper, these figures appeared most convincing; but, as the moment approached for my departure, I must confess to a sudden realization that they were based wholly upon theory, and I was struck with the utter folly of my mad venture.

For a moment I was aghast. The enormous torpedo, with its sixty tons, Iying there at the end of its mile long track, loomed above me, the semblance of a gargantuan coffin--my coffin, in which I was presently to be dashed to earth, or to the bottom of the Pacific, or cast out into space to wander there to the end of time. I was afraid. I admit it, but it was not so much the fear of death as the effect of the sudden realization of the stupendousness of the cosmic forces against which I had pitted my puny powers that temporarily unnerved me.

Then Jimmy spoke to me. "Let's have a last look at things inside the old crate before you shove off," he suggested, and my nervousness and my apprehensions vanished beneath the spell of his quiet tones and his matter-of-fact manner. I was myself again.

Together we inspected the cabin, where are located the controls, a wide and comfortable berth, a table, a chair, writing materials, and a well-stocked bookshelf. Behind the cabin is a small galley and just behind the galley a storeroom containing canned and dehydrated foods sufficient to last me a year. Back of this is a small battery room containing storage batteries for lighting, heating, and cooking, a dynamo, and a gas engine. The extreme stern compartment is filled with rockets and the intricate mechanical device by which they are fed to the firing chambers by means of the controls in the cabin. Forward of the main cabin is a large compartment in which are located the water and oxygen tanks, as well as a quantity of odds and ends necessary either to my safety or comfort.

Everything, it is needless to say, is fastened securely against the sudden and terrific stress that must accompany the take-off. Once out in space, I anticipate no sense of motion, but the start is going to be rather jarring. To absorb, as much as possible, the shock of the take-off, the rocket consists of two torpedoes, a smaller torpedo within a larger one, the former considerably shorter than the latter and consisting of several sections, each one comprising one of the compartments I have described. Between the inner and outer shells and between each two compartments is installed a system of ingenious hydraulic shock absorbers designed to more or less gradually overcome the inertia of the inner torpedo during the take-off. I trust that it functions properly.

In addition to these precautions against disaster at the start, the chair in which I shall sit before the controls is not only heavily overstuffed but is secured to a track or framework that is equipped with shock absorbers. Furthermore, there are means whereby I may strap myself securely into the chair before taking off.

I have neglected nothing essential to my safety, upon which depends the success of my project.

Following our final inspection of the interior, Jimmy and I clambered to the top of the torpedo for a last inspection of the parachutes, which I hope will sufficiently retard the speed of the rocket after it enters the atmosphere of Mars to permit me to bail out with my own parachute in time to make a safe landing. The main parachutes are in a series of compartments running the full length of the top of the torpedo. To explain them more clearly, I may say that they are a continuous series of batteries of parachutes, each battery consisting of a number of parachutes of increasing diameter from the uppermost, which is the smallest. Each battery is in an individual compartment, and each compartment is covered by a separate hatch that can be opened at the will of the operator by controls in the cabin. Each parachute is anchored to the torpedo by a separate cable. I expect about one half of them to be torn loose while checking the speed of the torpedo sufficiently to permit the others to hold and further retard it to a point where I may safely open the doors and jump with my own parachute and oxygen tank.

The moment for departure was approaching. Jimmy and I had descended to the ground and the most difficult ordeal now faced me--that of saying good-bye to these loyal friends and co-workers. We did not say much, we were too filled with emotion, and there was not a dry eye among us. Without exception none of the Mexican laborers could understand why the nose of the torpedo was not pointed straight up in the air if my intended destination were Marte. Nothing could convince them that I would not shoot out a short distance and make a graceful nose dive into the Pacific--that is, if I started at all, which many of them doubted.

There was a handclasp all around, and then I mounted the ladder leaning against the side of the torpedo and entered it. As I closed the door of the outer shell, I saw my friends piling into the trucks and pulling away, for I had given orders that no one should be within a mile of the rocket when I took off, fearing, as I did, the effect upon them of the terrific explosion that must accompany the take-off. Securing the outer door with its great vaultlike bolts, I closed the inner door and fastened it; then I took my seat before the controls and buckled the straps that held me to the chair.

I glanced at my watch. It lacked nine minutes of the zero hour. In nine minutes I should be on my way out into the great void, or in nine minutes I should be dead. If all did not go well, the disaster would follow within a fraction of a split second after I touched the first firing control.

Seven minutes! My throat felt dry and parched; I wanted a drink of water, but there was no time.

Four minutes! Thirty-five million miles are a lot of miles, yet I planned on spanning them in between forty and forty-five days.

Two minutes! I inspected the oxygen gauge and opened the valve a trifle wider.

One minute! I thought of my mother and wondered if she were way out there somewhere waiting for me.

Thirty seconds! My hand was on the control. Fifteen secondsl Ten, five, four, three, two-- one!

I turned the pointer! There was a muffled roar. The torpedo leaped forward. I was off!

I knew that the take-off was a success. I glanced through the port at my side at the instant that the torpedo started, but so terrific was its initial speed that I saw only a confused blur as the landscape rushed past. I was thrilled and delighted by the ease and perfection with which the take-off had been accomplished, and I must admit that I was not a little surprised by the almost negligible effects that were noticeable in the cabin. I had had the sensation as of a giant hand pressing me suddenly back against the upholstery of my chair but that had passed almost at once, and now there was no sensation different from that which one might experience sitting in an easy chair in a comfortable drawing-room on terra firma.

There was no sensation of motion after the first few seconds that were required to pass through the earth's atmosphere, and now that I had done all that lay within my power to do. I could only leave the rest to momentum, gravitation, and fate. Releasing the straps that held me to the chair, I moved about the cabin to look through the various ports, of which there were several in the sides, keel, and top of the torpedo Space was a black void dotted with countless points of light. The earth I could not see, for it lay directly astern; far ahead was Mars. All seemed well. I switched on the electric lights, and seating myself at the table, made the first entries in the log; then I checked over various computations of time and distances.

My calculations suggested that in about three hours from the take-off the torpedo would be moving almost directly toward Mars; and from time to time I took observations through the wide-angle telescopic periscope that is mounted flush with the upper surface of the torpedo's shell, but the results were not entirely reassuring. In two hours Mars was dead ahead--the arc of the trajectory was not flattening as it should. I became apprehensive. What was wrong? Where had our careful computations erred?

I left the periscope and gazed down through the main keel port. Below and ahead was the Moon, a gorgeous spectacle as viewed through the clear void of space from a distance some seventy-two thousand miles less than I had ever seen it before and with no earthly atmosphere to reduce visibility. Tycho, Plato, and Copernicus stood out in bold relief upon the brazen disc of the great satellite, deepening by contrast the shadows of Mare Serenitatis and Mare Tranquilitatis. The rugged peaks of the Apennine and the Altai lay revealed as distinctly as I had ever seen them through the largest telescope. I was thrilled, but I was distinctly worried, too.

Three hours later I was less than fifty-nine thousand miles from the Moon; where its aspect had been gorgeous before, it now beggared description, but my apprehension had cause to increase in proportion; I might say, as the square of its increasing gorgeousness. Through the periscope I had watched the arc of my trajectory pass through the plane of Mars and drop below it. I knew quite definitely then that I could never reach my goal. I tried not to think of the fate that lay ahead of me; but, instead, sought to discover the error that had wrought this disaster.

For an hour I checked over various calculations, but could discover nothing that might shed light on the cause of my predicament; then I switched off the lights and looked down through the keel port to have a closer view of the Moon. It was not there! Stepping to the port side of the cabin, I looked through one of the heavy circular glasses out into the void of space. For an instant I was horror stricken; apparently just off the port bow loomed an enormous world. It was the Moon, less than twenty-three thousand miles away, and I was hurtling toward it at the rate of thirty-six thousand miles an hourl

I leaped to the periscope, and in the next few seconds I accomplished some lightning mental calculating that must constitute an all-time record. I watched the deflection of our course in the direction of the Moon, following it across the lens of the periscope, I computed the distance to the Moon and the speed of the torpedo, and I came to the conclusion that I had better than a fighting chance of missing the great orb. I had little fear of anything but a direct hit, since our speed was so great that the attraction of the Moon could not hold us if we missed her even by a matter of feet; but it was quite evident that it had affected our flight, and with this realization came the answer to the question that had been puzzling me.

To my mind flashed the printer's story of the first perfect book. It had been said that no book had ever before been published containing not a single error. A great publishing house undertook to publish such a book. The galley proofs were read and reread by a dozen different experts, the page proofs received the same careful scrutiny. At last the masterpiece was ready for the press--errorlessl It was printed and bound and sent out to the public, and then it was discovered that the title had been misspelled on the title page. With all our careful calculation, with all our checking and rechecking, we had overlooked the obvious; we had not taken the Moon into consideration at all.

Explain it if you can; I cannot. It was just one of those things, as people say when a good team loses to a poor one; it was a break, and a bad one. How bad it was I did not even try to conjecture at the time; I just sat at the periscope watching the Moon racing toward us. As we neared it, it presented the most gorgeous spectacle that I have ever witnessed. Each mountain peak and crater stood out in vivid detail. Even the great height of summits over twenty-five thousand feet appeared distinguishable to me, though imagination must have played a major part in the illusion, since I was looking down upon them from above.

Suddenly I realized that the great sphere was passing rapidly from the field of the periscope, and I breathed a sigh of relief--we were not going to score a clean hit, we were going to pass by.

I returned then to the porthole. The Moon lay just ahead and a little to the left. It was no longer a great sphere; it was a world that filled my whole range of vision. Against its black horizon I saw titanic peaks; below me huge craters yawned. I stood with God on high and looked down upon a dead world.

Our transit of the Moon required a little less than four minutes; I timed it carefully that I might check our speed. How close we came I may only guess; perhaps five thousand feet above the tallest peaks, but it was close enough. The pull of the Moon's gravitation had definitely altered our course, but owing to our speed we had eluded her clutches. Now we were racing away from her, but to what?

The nearest star, Alpha Centauri, is twenty-five and a half million million miles from earth. Write that on your typewriter--25,500,000,000,000 miles. But why trifle with short distances like this? There was little likelihood that I should visit Alpha Centauri with all the wide range of space at my command and many more interesting places to go. I knew that I had ample room in which to wander, since science has calculated the diameter of space to be eighty-four thousand million light years, which, when one reflects that light travels at the rate of one hundred eighty-six thousand miles a second, should satisfy the wanderlust of the most inveterate roamer.

However, l was not greatly concerned with any of these distances, as I had food and water for only a year, during which time the torpedo might travel slightly more than three hundred fifteen million miles. Even if it reached our near neighbor, Alpha Centauri, I should not then be greatly interested in the event, as I should have been dead for over eighty thousand years. Such is the immensity of the universel

During the next twenty-four hours the course of the torpedo nearly paralleled the Moon's orbit around the earth. Not only had the pull of the Moon deflected its course, but now it seemed evident that the earth had seized us and that we were doomed to race through eternity around her, a tiny, second satellite. But I did not wish to be a moon, certainly not an insignificant moon that in all probability might not be picked up by even the largest telescope.

The next month was the most trying of my life. It seems the height of egotism even to mention my life in the face of the stupendous cosmic forces that engulfed it; but it was the only life I had and I was fond of it, and the more imminent seemed the moment when it should be snuffed out, the better I liked it.

At the end of the second day it was quite apparent that we had eluded the grip of the earth. I cannot say that I was elated at the discovery. My plan to visit Mars was ruined. I should have been glad to return to earth. If I could have landed safely on Mars, I certainly could have landed safely on earth. But there was another reason why I should have been glad to have returned to earth, a reason that loomed, large and terrible, ahead--the Sun. We were heading straight for the Sun now. Once in the grip of that mighty power, nothing could affect our destiny; we were doomed. For three months I must await the inevitable end, before plunging into that fiery furnace. Furnace is an inadequate word by which to suggest the Sun's heat, which is reputedly from thirty to sixty million degrees at the center, a fact which should not have concerned me greatly, since I did not anticipate reaching the center.

The days dragged on, or, I should say, the long night--there were no days, other than the record that I kept of the passing hours. I read a great deal. I made no entries in the log. Why write something that was presently to be plunged into the Sun and consumed? I experimented in the galley, attempting fancy cooking. I ate a great deal; it helped to pass the time away, and I enjoyed my meals.

On the thirtieth day I was scanning space ahead when I saw a gorgeous, shimmering crescent far to the right of our course; but I must confess that I was not greatly interested in sights of any sort. In sixty days I should be in the Sun. Long before that, however, the increasing heat would have destroyed me. The end was approaching rapidly.
