Some things I might believe of Orthis, but not this.

And during these nine years since graduation, as we had drifted apart in interests, so had the breach between us been widened by constantly increasing difference in rank. He was a Lieutenant Commander and I a Captain, when in 2024 he announced the discovery and isolation of the Eighth Solar Ray, and within two months those of the Moon, Mercury, Venus and Jupiter. The Eighth Barsoomian and the Eighth Earthly Rays had already been isolated, and upon Earth the latter erroneously called by the name of the former.

Orthis' discoveries were hailed upon two planets as the key to actual travel between the Earth and Barsoom, since by means of these several rays the attraction of the Sun and the planets, with the exception of Saturn, Uranus and Neptune, could be definitely overcome and a ship steer a direct and unimpeded course through space to Mars. The effect of the pull of the three farther planets was considered negligible, owing to their great distance from both Mars and Earth.

Orthis wanted to equip a ship and start at once, but again government intervened and forbade what it considered an unnecessary risk. Instead Orthis was ordered to design a small radio operated flier, which would carry no one aboard, and which it was believed could be automatically operated for at least half the distance between the two planets. After his designs were completed, you may imagine his chagrin, and mine as well, when I was detailed to supervise construction, yet I will say that Orthis hid his natural emotions well and gave me perfect cooperation in the work we were compelled to undertake together, and which was as distasteful to me as to him. On my part I made it as easy for him as I could, working with him rather than over him.

It required but a short time to complete the experimental ship and during this time I had an opportunity to get a still better insight into the marvelous intellectual ability of Orthis, though I never saw into his mind or heart.

It was late in 2024 that the ship was launched upon its strange voyage, and almost immediately, upon my recommendation, work was started upon the perfection of the larger ship that had been in course of construction in 2015 at the time that the loss of the Martian ship had discouraged our government in making any further attempt until the then seemingly insurmountable obstacles should have been overcome. Orthis was again my assistant, and with the means at our disposal it was a matter of less than eight months before The Barsoom, as she was christened, was completely overhauled and thoroughly equipped for the interplanetary voyage. The various eighth rays that would assist us in overcoming the pull of the Sun, Mercury, Venus, Earth, Mars and Jupiter were stored in carefully constructed and well protected tanks within the hull, and there was a smaller tank at the bow containing the Eighth Lunar Ray, which would permit us to pass safely within the zone of the moon's influence without danger of being attracted to her barren surface.

Messages from the original Martian ship had been received from time to time and with diminishing strength for nearly five years after it had left Mars. Its commander in his heroic fight against the pull of the sun had managed to fall within the grip of Jupiter and was, when last heard from, far out in the great void between that planet and Mars. During the past four years the fate of the ship could be naught but conjecture -- all that we could be certain of was that its unfortunate crew would never again return to Barsoom.

Our own experimental ship had been speeding upon its lonely way now for eight months, and so accurate had Orthis' scientific deductions proven that the most delicate instrument could detect no slightest deviation from its prescribed course. It was then that Orthis began to importune the government to permit him to set out with the new craft that was now completed. The authorities held out, however, until the latter part of 2025 when, the experimental ship having been out a year and still showing no deviation from its course, they felt reasonably assured that the success of the venture was certain and that no useless risk of human life would be involved.

The Barsoom required five men properly to handle it, and as had been the custom through many centuries when an undertaking of more than usual risk was to be attempted, volunteers were called for, with the result that fully half the personnel of the International Peace Fleet begged to be permitted to form the crew of five.

The government finally selected their men from the great number of volunteers, with the result that once more was I the innocent cause of disappointment and chagrin to Orthis, as I was placed in command, with Orthis, two lieutenants and an ensign completing the roster.

The Barsoom was larger than the craft dispatched by the Martians, with the result that we were able to carry supplies for fifteen years. We were equipped with more powerful motors which would permit us to maintain an average speed of over twelve hundred miles an hour, carrying in addition an engine recently developed by Orthis which generated sufficient power from light to propel the craft at half-speed in the event that our other engine should break down. None of us was married, Orthis' abandoned wife having recently died. Our estates were taken under trusteeship by the government. Our farewells were made at an elaborate ball at the White House on December 24, 2025, and on Christmas day we rose from the landing stage at which The Barsoom had been moored, and amid the blare of bands and the shouting of thousands of our fellow countrymen we arose majestically into the blue.

I shall not bore you with dry, technical descriptions of our motors and equipment. Suffice it to say that the former were of three types -- those which propelled the ship through the air and those which propelled it through ether, the latter of course represented our most important equipment, and consisted of powerful multiple-exhaust separators which isolated the true Barsoomian Eighth Ray in great quantities, and, by exhausting it rapidly earthward, propelled the vessel toward Mars. These separators were so designed that, with equal facility, they could isolate the Earthly Eighth Ray which would be necessary for our return voyage. The auxiliary engine, which I mentioned previously and which was Orthis' latest invention, could be easily adjusted to isolate the eighth ray of any planet or satellite or of the sun itself, thus insuring us motive power in any part of the universe by the simple expedient of generating and exhausting the eighth ray of the nearest heavenly body. A fourth type of generator drew oxygen from the ether, while another emanated insulating rays which insured us a uniform temperature and external pressure at all times, their action being analogous to that of the atmosphere surrounding the earth. Science had, therefore, permitted us to construct a little world, which moved at will through space -- a little world inhabited by five souls.

Had it not been for Orthis' presence I could have looked forward to a reasonably pleasurable voyage, for West and Jay were extremely likeable fellows and sufficiently mature to be companionable, while young Norton, the ensign, though but seventeen years of age, endeared himself to all of us from the very start of the voyage by his pleasant manners, his consideration and his willingness in the performance of his duties. There were three staterooms aboard The Barsoom, one of which I occupied alone, while West and Orthis had the second and Jay and Norton the third. West and Jay were lieutenants and had been classmates at the air school. They would of course have preferred to room together, but could not unless I commanded it or Orthis requested it. Not wishing to give Orthis any grounds for offense I hesitated to make the change, while Orthis, never having thought a considerate thought or done a considerate deed in his life, could not, of course, have been expected to suggest it. We all messed together, West, Jay and Norton taking turns at preparing the meals. Only in the actual operation of the ship were the lines of rank drawn strictly. Otherwise we associated as equals, nor would any other arrangement have been endurable upon such an undertaking, which required that we five be practically imprisoned together upon a small ship for a period of not less than five years. We had books and writing materials and games, and we were, of course, in constant radio communication with both Earth and Mars, receiving continuously the latest news from both planets.
