Melvar." No time was to be lost. I had been anticipating something of the kind. The guns were cleaned and loaded. My pack was soon ready. Naro took a part of my equipment. I followed the boy up the stair, with the phrase, "For I loved you," ringing in my heart. We reached the top and walked out into the red brush. Beneath the purple starlight the vast fantastic columned halls of Astran were gleaming faintly, and I caught a brief blue flicker from the great machine on the ruby dome. Suddenly, with a sharp thrill of terror that made me catch my breath, I heard the awful distant whining sigh that grew until it rolled and reverberated through the heavens, and the air seemed alive with its deep intensity. Above the emerald wall I glimpsed the green-tipped needle of crimson that made the sound. It was sweeping through the sky meteor-swift, while the pale blue beam stabbed out at it ineffectually. It passed in an instant, but others came, and soon the sky was lighted with the weird red radiance, and the very mountain top vibrated with the whistling roars. The things swept around and around in a mad confusion of darting flames. They were like moths about a candle. We passed an amber palace wall and came suddenly upon a great, metal-floored court. Marching across it were a half score of the Astranian men-at-arms, their accoutrements gleaming weirdly in the light of the strange things above. They saw us at once, and charged upon us with a shout. I dropped to my knees. Once my rifle spoke, and I rejoiced at its heavy thrust against my shoulder, and the acrid odor of the smoke. I felt a man again. And the leader of the soldiers fell upon his face. * * * * * Melvar Saved Naro gripped my shoulder and pointed upward. One of the red things was plunging down, like a great red Zeppelin with a great green light at its forward end, its purple phosphorescent track swirling up behind it. The soldiers forgot us and scattered in mad terror. Naro jerked my arm and in a moment we had tumbled into a copse of the red brush. For a moment the bloody radiance was thrown upon us in an intense flood, and the screaming roar was deafening. A few minutes more, and the thing had flashed up and away. A breath of hot purple mist passed over us. When we got to our feet and crept out of the thicket the soldiers were gone. Swiftly, Naro led me on, keeping in the shadows of the building, on in the cover of the thickets. Once a man sprang suddenly at us from behind a sapphire pillar, diamond sword drawn. My pistol exploded in his face and blew his head half off. Naro possessed himself of the dead man's weapons, and we went breathlessly on. Three times, in other parts of the city, we saw the red shapes drop to the ground for a few minutes, and then dart up again, while ever the blue ray played back and forth upon them.
