The three rushed straight on toward us, disregarding the rushing wall of flame not a dozen yards to the right of them. I kept firing madly. The leg of one went limp, but he leapt on with scarcely diminished speed, laughing terribly, with the white hair flying about the awful face, and the purple limbs moving frenziedly. The flames rushed over the fallen two and hid them. In another instant the curtain of fire had rolled over the others, and even the ship was hidden from our view.
Suddenly I realized that we were in quite as much danger from the fire as from the monsters. Already we were shrinking from the hot wind that blew before the flames, and half choked by the acrid fumes. For the second time we made a mad retreat to the top of the boulder, and lay flat. I heard a terrible laugh from the flames, and in a moment one of the things dashed out. His hair was gone, and the purple flesh burnt black. I shot as it showed itself, and it fell. In another instant the flames had raced over it again. None of the others appeared.
We lay on the rock for several minutes, gasping in the cooler air that lingered near its surface. For a time the heat was stifling, but the scanty vegetation had burned off quickly, and soon a cool breeze came up from the south and lifted the smoke. We saw that the cylinder still lay where it had been, although the heavy body was closed. The green light still shone in the forward end. About it the earth lay black and smoking, and a low line of flame lay below the pall of smoke in a great ring all about us. Between us and the ship I saw in the darkness the black shadows that were the five dead beasts.
I was just beginning to wonder if all the crew of the ship were dead, so that we might enter and examine it, when the great oval door in the side swung open again, and something sprang out of it into the night. I heard a strange hissing, and a clatter of metal. In the semi-darkness I could see nothing plainly, but there was a floating shape of greenish mist, with a vague form beneath. I strained my eyes to try to distinguish its shape, while it stood motionless.
Abruptly a narrow, intensely bright beam of orange light shot out of it and impinged upon the rock. There was a dull thud from the rock, and the ray was dead in a moment. But the granite where it had struck was cut away—obliterated! The beam had shone straight through the boulder, carrying away, or resolving into primary electrons, the matter on which it had struck! The smooth edges of the cut were glowing with a soft violet radiance.
My rifle was at hand, and on recovering from my surprise, I fired. I aimed just below the greenish patch. Something must have been exploded by the bullet, for there was a vivid flash of white fire, and a loud, sharp report. The spot of green was visible no longer, and we saw no motion about the cylinder. At the time I had no idea what it was that I had shot. I supposed that it had been another of the purple beasts armed with a strange ray weapon. I imagined that the bullet had struck the weapon and caused an explosion.
CHAPTER IX
The Battle in the Mist
For perhaps an hour we sat there on the rock. As soon as the smoke cleared, we could see the crimson needles flying high upon their vague red tracks, and we watched them with a sort of hypnotic fascination, dreading the moment when one of them would land to investigate the fate of the ship that lay silent and presumably empty before us. The ground was still too hot for us to walk upon, and we felt the uselessness of attempting to escape on foot, even if it had already cooled. With a feeling of resigned and hopeless horror, we saw one of the crimson pencils circle lower about the place, then disappear in the direction of its lair beyond the Silver Lake.
