"How to get rid of our excessive carbon dioxide without unduly wasting our oxygen is a delicate and vital question," said Challenger, looking round him after the five iron tubes had been laid side by side against the wall. "With longer time for preparation I could have brought the whole concentrated force of my intelligence to bear more fully upon the problem, but as it is we must do what we can. The shrubs will be of some small service. Two of the oxygen tubes are ready to be turned on at an instant's notice, so that we cannot be taken unawares. At the same time, it would be well not to go far from the room, as the crisis may be a sudden and urgent one."
There was a broad, low window opening out upon a balcony. The view beyond was the same as that which we had already admired from the study. Looking out, I could see no sign of disorder anywhere. There was a road curving down the side of the hill, under my very eyes. A cab from the station, one of those prehistoric survivals which are only to be found in our country villages, was toiling slowly up the hill. Lower down was a nurse girl wheeling a perambulator and leading a second child by the hand. The blue reeks of smoke from the cottages gave the whole widespread landscape an air of settled order and homely comfort. Nowhere in the blue heaven or on the sunlit earth was there any foreshadowing of a catastrophe. The harvesters were back in the fields once more and the golfers, in pairs and fours, were still streaming round the links. There was so strange a turmoil within my own head, and such a jangling of my overstrung nerves, that the indifference of those people was amazing.
"Those fellows don't seem to feel any ill effects," said I, pointing down at the links.
"Have you played golf?" asked Lord John.
"No, I have not."
"Well, young fellah, when you do you'll learn that once fairly out on a round, it would take the crack of doom to stop a true golfer. Halloa! There's that telephone-bell again."
From time to time during and after lunch the high, insistent ring had summoned the Professor. He gave us the news as it came through to him in a few curt sentences. Such terrific items had never been registered in the world's history before. The great shadow was creeping up from the south like a rising tide of death. Egypt had gone through its delirium and was now comatose. Spain and Portugal, after a wild frenzy in which the Clericals and the Anarchists had fought most desperately, were now fallen silent. No cable messages were received any longer from South America. In North America the southern states, after some terrible racial rioting, had succumbed to the poison. North of Maryland the effect was not yet marked, and in Canada it was hardly perceptible. Belgium, Holland, and Denmark had each in turn been affected. Despairing messages were flashing from every quarter to the great centres of learning, to the chemists and the doctors of world-wide repute, imploring their advice. The astronomers too were deluged with inquiries. Nothing could be done. The thing was universal and beyond our human knowledge or control. It was death-painless but inevitable-death for young and old, for weak and strong, for rich and poor, without hope or possibility of escape. Such was the news which, in scattered, distracted messages, the telephone had brought us. The great cities already knew their fate and so far as we could gather were preparing to meet it with dignity and resignation. Yet here were our golfers and laborers like the lambs who gambol under the shadow of the knife. It seemed amazing. And yet how could they know? It had all come upon us in one giant stride. What was there in the morning paper to alarm them? And now it was but three in the afternoon. Even as we looked some rumour seemed to have spread, for we saw the reapers hurrying from the fields. Some of the golfers were returning to the club-house. They were running as if taking refuge from a shower. Their little caddies trailed behind them. Others were continuing their game. The nurse had turned and was pushing her perambulator hurriedly up the hill again. I noticed that she had her hand to her brow. The cab had stopped and the tired horse, with his head sunk to his knees, was resting. Above there was a perfect summer sky-one huge vault of unbroken blue, save for a few fleecy white clouds over the distant downs. If the human race must die to-day, it was at least upon a glorious death-bed. And yet all that gentle loveliness of nature made this terrific and wholesale destruction the more pitiable and awful. Surely it was too goodly a residence that we should be so swiftly, so ruthlessly, evicted from it!
But I have said that the telephone-bell had rung once more. Suddenly I heard Challenger's tremendous voice from the hall.
"Malone!" he cried. "You are wanted." I rushed down to the instrument. It was McArdle speaking from London.
"That you, Mr. Malone?" cried his familiar voice. "Mr. Malone, there are terrible goings-on in London. For God's sake, see if Professor Challenger can suggest anything that can be done."
"He can suggest nothing, sir," I answered. "He regards the crisis as universal and inevitable. We have some oxygen here, but it can only defer our fate for a few hours."
"Oxygen!" cried the agonized voice. "There is no time to get any. The office has been a perfect pandemonium ever since you left in the morning. Now half of the staff are insensible. I am weighed down with heaviness myself. From my window I can see the people lying thick in Fleet Street. The traffic is all held up. Judging by the last telegrams, the whole world-"
His voice had been sinking, and suddenly stopped. An instant later I heard through the telephone a muffled thud, as if his head had fallen forward on the desk.
"Mr. McArdle!" I cried. "Mr. McArdle!"
There was no answer. I knew as I replaced the receiver that I should never hear his voice again.
At that instant, just as I took a step backwards from the telephone, the thing was on us. It was as if we were bathers, up to our shoulders in water, who suddenly are submerged by a rolling wave. An invisible hand seemed to have quietly closed round my throat and to be gently pressing the life from me. I was conscious of immense oppression upon my chest, great tightness within my head, a loud singing in my ears, and bright flashes before my eyes. I staggered to the balustrades of the stair. At the same moment, rushing and snorting like a wounded buffalo, Challenger dashed past me, a terrible vision, with red-purple face, engorged eyes, and bristling hair. His little wife, insensible to all appearance, was slung over his great shoulder, and he blundered and thundered up the stair, scrambling and tripping, but carrying himself and her through sheer will-force through that mephitic atmosphere to the haven of temporary safety. At the sight of his effort I too rushed up the steps, clambering, falling, clutching at the rail, until I tumbled half senseless upon by face on the upper landing. Lord John's fingers of steel were in the collar of my coat, and a moment later I was stretched upon my back, unable to speak or move, on the boudoir carpet. The woman lay beside me, and Summerlee was bunched in a chair by the window, his head nearly touching his knees. As in a dream I saw Challenger, like a monstrous beetle, crawling slowly across the floor, and a moment later I heard the gentle hissing of the escaping oxygen. Challenger breathed two or three times with enormous gulps, his lungs roaring as he drew in the vital gas.
