A few moments after, another and a brighter flash of lightning lit up the gloomy swamp, and almost simultaneously the thunder bellowed out in a quick succession of cracking reports, dying away in rumblings and growlings which were tossed from echo to echo in the wilderness. Then down came the rain in a drowning deluge, roaring on the foliage, and churning the surface of the sleeping lake into a torrent of bubbling, boiling foam. Towards the end of the storm we had another surprise, which filled us with the direst alarm. An exclamation from Temple brought us all to the window of the _Sirius_ which overlooked the lake. With blanched face, and eyes fixed intently upon the water, he pointed to the seething pool. "Tell me if I am mad or dreaming," he shouted in his terror. [Illustration: ITS HUGE, SCALY CARCASS.] Truly, indeed, his alarm was not without cause, for there, coming slowly from the water on to the shore, and in the direction of the _Sirius_, was the first representative we had seen of animal life in Mars. How shall we attempt to describe this hideous amphibious monster, as it appeared lit up by the almost incessant flashes of lightning? Only its enormous head and forequarters were yet visible--a huge scaly carcase, mapped out with phosphorescent light, a square-looking head with pointed snout, and with two monstrous eyes attached to stalk-like shafts about a foot in length, which in the brief intervals of darkness shone like balls of fire. Raising its head on its long pliant neck, it sniffed the air as if in anger, and then began to crawl out of the pool, yard after yard of its repulsive body emerging, its head nearly reaching the _Sirius_ before its tapering fish-like tail was drawn from the water. We could hear the grinding, crunching sound of its scaly body as it was slowly drawn along the swampy ground, and so near had it come to us that we could see a coarse, bushy mane hanging round its lower neck in dripping folds. The hideous reptile, for such we must call it, passed on without noticing the _Sirius_, although we felt its rough, scaly body rub against the sides; and as its hideous, mighty coils disappeared into the gloomy swamp, leaving a luminous, slimy track behind them we could detect huge protuberances like warts along its back, here and there varied with spiky fins, which were from time to time half-raised, as though the horrible creature were about to engage in combat. "Doctor," said Temple, in his alarm, "if this is a fair sample of the creatures we have come to live amongst, I really think it time we began to think about getting back again. I don't like the idea of such neighbours at all. Besides, we may yet meet with monsters more terrible still, and what is of greater importance to us, we may not escape their notice so easily next time. We should require an army to protect us from such creatures as this." "Gently, gently, Temple; you are not a naturalist, and cannot be expected to feel my enthusiasm."
