I think the fellow was just on the point of launching his spear at me, when I fired. The bullet struck him square between the eyes, and he dropped like a log, without a sound. Instantly, the others wheeled again and galloped away, this time evincing speed that was almost appalling, clearing spaces of a hundred feet in a single bound, even though handicapped, as they must have been, by the weapons which they clutched in their fore-paws. A glance behind me showed the dust-cloud rapidly approaching the river, upon the mainland, and calling to Orthis to follow me, I ran rapidly along the trail which led back in the direction of the ship. The four Moon creatures retreated for about half a mile, and then halted and faced us. They were still directly in our line of retreat, and there they stood for a moment, evidently discussing their plans. We were nearing them rapidly, for we had discovered that we, too, could show remarkable speed, when retarded by gravity only one-sixth of that of Earth. To clear forty feet at a jump was nothing, our greatest difficulty lying in a tendency to leap to too great heights, which naturally resulted in cutting down our horizontal distance. As we neared the four, who had taken their stand upon the summit of a knoll, I heard a great splashing in the river behind us, and turning, saw that their reinforcements were crossing the ford, and would soon be upon us. There appeared to be fully a hundred of them, and our case looked hopeless indeed, unless we could manage to pass the four ahead of us, and reach the comparative safety of the forest beyond the first ford. “Commence firing, Orthis,” I said. “Shoot to kill. Take the two at the left as your targets, and I’ll fire at the two at the right. We had better halt and take careful aim, as we cannot afford to waste ammunition.” We came to a stop about twenty-five yards from the foremost creature, which is a long pistol shot; but they were standing still upon the crest of a knoll, distinctly outlined against the sky, and were such a size as to present a most excellent target. Our shots rang out simultaneously. The creature at the left, at which Orthis had aimed, leaped high into the air, and fell to the ground, where it lay kicking convulsively. The one at the right uttered a piercing shriek, clutched at its breast, and dropped dead. Then Orthis and I charged the remaining two, while behind us we heard loud weird cries and the pounding of galloping feet. The two before us did not retreat this time, but came to meet us, and again we halted and fired. This time they were so close that we could not miss them, and the last of our original lunar foemen lay dead before us.
