The malarious vapours rising from the stagnant water and the rotting vegetation were deadly in their subtleness, and in spite of our ever-increasing excitement and curiosity, Doctor Hermann insisted for our health's sake that we should return to the _Sirius_. A night amidst such poisonous gases might have stricken each one of us down with a fatal fever. It was well that we did so, for before morning dawned the dangers of our position were manifested in various startling ways. Soon, huge banks of black clouds spread across the sky like shrouds, and drops of rain began to patter on the windows. "My friends," said Doctor Hermann, "the best advice I can give is that we stay inside the _Sirius_ until dawn. Sandy had better prepare us some food; we have not eaten for the past eight hours, and it is of the greatest importance that we take every care of ourselves, for we may have our strength and endurance put to the severest tests in the near future. Besides, this marsh is full of pestilence; we cannot be too careful: and, further, from the closeness of the atmosphere and the look of the heavens, I predict a storm within the next hour or so." "You are quite right, Doctor," rejoined Temple; whilst Sandy, as became the dutiful servant he was, began to act on the Doctor's wishes, and very soon had spread before us a right royal repast, which bore ample testimony not only to his culinary skill, but to the still ample resources of our larder. A bottle of our best wine was uncorked in honour of the occasion, and we sat down well-prepared to do justice to what Temple called our "triumphal feast." Convivial and merry was our meal, notwithstanding the dismal surroundings; and so gay and light-hearted did we feel that even the reeking swamp was toasted, for, after all, in spite of its gloom and its pestilential breath, it was the first ground to echo our foot-falls on this new world. "One more bottle of wine, my comrades," said Temple, as soon as our meal was over, "and let Sandy have a double allowance of whisky to-night. We must inaugurate the termination of our journey in a right festive way." "What a triumph for Science, for Electricity in particular, we have won!" said Doctor Hermann. "Here's to our continued success, and to the people of Mars, if such there be----" But before the Doctor could complete his toast the whole apartment was filled with a lurid flash of bluish light, and before we could recover from our surprise the vault of heaven was shaken by an appalling peal of thunder. "The storm is on us, Doctor," exclaimed Graham, "and to all appearance it is far too close to be pleasant."
