the most was the possibility of an actual exchange of visits between Earth Men and Barsoomians. Each planet hoped to be the first to achieve this, yet neither withheld any information that would aid the other in the consummation of the great fact. It was a generous and friendly rivalry which about the time of my graduation from the Air School seemed, in theory at least, to be almost ripe for successful consummation by one or the other. We had the Eighth Ray, the motors, the oxygenating devices, the insulating processes—everything to insure the safe and certain transit of a specially designed air craft to Mars, were Mars the only other inhabitant of space. But it was not and it was the other planets and the Sun that we feared.
In 2015 Mars had dispatched a ship for Earth with a crew of five men provisioned for ten years. It was hoped that with good luck the trip might be made in something less than five years, as the craft had developed an actual trial speed of one thousand miles per hour. At the time of my graduation the ship was already off its course almost a million miles and generally conceded to be hopelessly lost. Its crew, maintaining constant radio communication with both Earth and Mars, still hoped for success, but the best informed upon both worlds had given them up.
We had had a ship about ready at the time of the sailing of the Martians, but the government at Washington had forbidden the venture when it became apparent that the Barsoomian ship was doomed—a wise decision, since our vessel was no better equipped than theirs. Nearly ten years elapsed before anything further was accomplished in the direction of assuring any greater hope of success for another interplanetary venture into space, and this was directly due to the discovery made by a former classmate of mine, Lieutenant Commander Orthis, one of the most brilliant men
