Whether our shot had done any damage, beyond making the circular opening in the cloud curtain, we could not tell, for almost immediately the surrounding black smoke masses billowed in to fill up the hole. But in the brief glimpse we had caught sight of two or three large air ships hovering in space above that part of the Lake of the Sun and its bordering city which we had beheld. It seemed to me in the brief glance I had that one ship had been touched by the discharge and was wandering in an erratic manner. But the clouds closed in so rapidly that I not be certain. Penetrating the Cloud. Anyhow, we had demonstrated one thing, and that was that we could penetrate the cloud shield and reach the Martians in their hiding place. It had been prearranged that the first discharge from the flagship should be a signal for the concentration of the fire of all the other ships upon the same spot. A little hesitation, however, occurred, and a half a minute had elapsed before the disintegrators from the other members of the squadron were got into play. The Martians' Artificial Day. Then, suddenly we saw an immense commotion in the cloud beneath us. It seemed to be beaten and hurled in every direction and punctured like a sieve with nearly a hundred great circular holes. Through these gaps we could see clearly a large region of the planet's surface, with many airships floating above it, and the blaze of innumerable electric lights illuminating it. The Martians had created an artificial day under the curtain. This time there was no question that the blow had been effective. Four or five of the airships, partially destroyed, tumbled headlong toward the ground, while even from our great distance there was unmistakable evidence that fearful execution had been done among the crowded structures along the shore of the Lake. As each of our ships possessed but one of the new disintegrators, and since a minute or so was required to adjust them for a fresh discharge, we remained for a little while inactive after delivering the blow. Meanwhile the cloud curtain, though rent to shreds by the concentrated discharge of the disintegrators, quickly became a uniform black sheet again, hiding everything. We had just had time to congratulate ourselves on the successful opening of our bombardment, and the disintegrator of the flagship was poised for another discharge, when suddenly out of the black expanse beneath, quivered immense electric beams, clear cut and straight as bars of steel, but dazzling our eyes with unendurable brilliance. It was the reply of the Martians to our attack. Devastating Our Army. Three or four of the electrical ships were seriously damaged, and one, close beside the flagship, changed color, withered and collapsed, with the same sickening phenomena that had made our hearts shudder when the first disaster of this kind occurred during our brief battle over the asteroid.
