The distance of Mars from us was only about three times its own diameter, consequently it shut off a large part of the sky, as viewed from our position. But in order to see its whole surface it was necessary to go a little beyond the edge of the satellite, on that side which faced Mars. At the suggestion of Colonel Smith, who had so frequently stalked Indians that devices of this kind readily occurred to his mind, the sentinels all wore garments corresponding in color to that of the soil of the asteroid, which was of a dark, reddish brown hue. This would tend to conceal them from the prying eyes of the Martians. The commander himself frequently went around the edge of the planet in order to take a look at Mars, and I often accompanied him. I shall never forget one occasion, when, lying flat on the ground, and cautiously worming our way around on the side toward Mars, we had just begun to observe it with our telescopes, when I perceived, against the vast curtain of smoke, a small, glinting object, which I instantly suspected to be an airship. I called Mr. Edison's attention to it, and we both agreed that it was, undoubtedly, one of the Martian's aerial vessels, probably on the lookout for us. A short time afterward a large number of airships made their appearance at the upper surface of the clouds, moving to and fro, and although, with our glasses, we could only make out the general form of the ships, without being able to discern the Martians upon them, yet we had not the least doubt but they were sweeping the sky in every direction in order to determine whether we had been completely destroyed or had retreated to a distance from the planet. Even when that side of Mars on which we were looking had passed into night, we could still see the guardships circling above the clouds, their presence being betrayed by the faint twinkling of the electric lights that they bore. Finally, after about a week had passed, the Martians evidently made up their minds that they had annihilated us, and that there was no longer danger to be feared. Convincing evidence that they believed we should not be heard from again was furnished when the withdrawal of the great curtain of cloud began. This phenomenon first manifested itself by a gradual thinning of the vaporous shield, until, at length, we began to perceive the red surface of the planet dimly shining through it. Thinner and rarer it became, and, after the lapse of about eighteen hours, it had completely disappeared, and the huge globe shone out again, reflecting the light of the sun from its continents and oceans with a brightness that, in contrast with the all-enveloping night to which we had so long been subjected, seemed unbearable to our eyes.
