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."

No less than nine of these terrible monsters came from the lake during the hour that we watched, and all took the same beaten track into the swamps that the first had followed, and we saw them no more. Temple could scarcely conceal a shudder, as he looked at the now placid water. "Ah!" he exclaimed, "who would have dreamed that such creatures were lying beneath its surface?"

Certainly the Doctor alarmed us, when we heard him coolly bidding Sandy to seek and slaughter these loathsome creatures.

"Sandy," said he, "you must get me one of those serpents to morrow. It will be most interesting to dissect so magnificent a type of the Reptilia. I may not have another such opportunity."

"Na, na, Doctor, I could na do it—I could na do it, mon," he replied deprecatingly.

"Doctor, I am afraid, if you press your request, we shall have Sandy wanting to give us all a week's notice," said Graham, assuming an air of mock gravity as he spoke.

"I dinna want to do anything o' the kind, Mr. Graham."
