Lord John shook his head gravely.
"You'll be gettin' into serious trouble some of these days if you don't put a brake on," said he.
"Perhaps you have some observation to make, Summerlee?"
"You should drop all work instantly, Challenger, and take three months in a German watering-place," said he.
"Profound! Profound!" cried Challenger. "Now, my young friend, is it possible that wisdom may come from you where your seniors have so signally failed?"
And it did. I say it with all modesty, but it did. Of course, it all seems obvious enough to you who know what occurred, but it was not so very clear when everything was new. But it came on me suddenly with the full force of absolute conviction.
"Poison!" I cried.
Then, even as I said the word, my mind flashed back over the whole morning's experiences, past Lord John with his buffalo, past my own hysterical tears, past the outrageous conduct of Professor Summerlee, to the queer happenings in London, the row in the park, the driving of the chauffeur, the quarrel at the oxygen warehouse. Everything fitted suddenly into its place.
"Of course," I cried again. "It is poison. We are all poisoned."
"Exactly," said Challenger, rubbing his hands, "we are all poisoned. Our planet has swum into the poison belt of ether, and is now flying deeper into it at the rate of some millions of miles a minute. Our young friend has expressed the cause of all our troubles and perplexities in a single word, `poison.'"
We looked at each other in amazed silence. No comment seemed to meet the situation.
"There is a mental inhibition by which such symptoms can be checked and controlled," said Challenger. "I cannot expect to find it developed in all of you to the same point which it has reached in me, for I suppose that the strength of our different mental processes bears some proportion to each other. But no doubt it is appreciable even in our young friend here. After the little outburst of high spirits which so alarmed my domestic I sat down and reasoned with myself. I put it to myself that I had never before felt impelled to bite any of my household. The impulse had then been an abnormal one. In an instant I perceived the truth. My pulse upon examination was ten beats above the usual, and my reflexes were increased. I called upon my higher and saner self, the real G. E. C., seated serene and impregnable behind all mere molecular disturbance. I summoned him, I say, to watch the foolish mental tricks which the poison would play. I found that I was indeed the master. I could recognize and control a disordered mind. It was a remarkable exhibition of the victory of mind over matter, for it was a victory over that particular form of matter which is most intimately connected with mind. I might almost say that mind was at fault and that personality controlled it. Thus, when my wife came downstairs and I was impelled to slip behind the door and alarm her by some wild cry as she entered, I was able to stifle the impulse and to greet her with dignity and restraint. An overpowering desire to quack like a duck was met and mastered in the same fashion.
Later, when I descended to order the car and found Austin bending over it absorbed in repairs, I controlled my open hand even after I had lifted it and refrained from giving him an experience which would possibly have caused him to follow in the steps of the housekeeper. On the contrary, I touched him on the shoulder and ordered the car to be at the door in time to meet your train. At the present instant I am most forcibly tempted to take Professor Summerlee by that silly old beard of his and to shake his head violently backwards and forwards. And yet, as you see, I am perfectly restrained. Let me commend my example to you."
"I'll look out for that buffalo," said Lord John.
"And I for the football match." "It may be that you are right, Challenger," said Summerlee in a chastened voice. "I am willing to admit that my turn of mind is critical rather than constructive and that I am not a ready convert to any new theory, especially when it happens to be so unusual and fantastic as this one. However, as I cast my mind back over the events of the morning, and as I reconsider the fatuous conduct of my companions, I find it easy to believe that some poison of an exciting kind was responsible for their symptoms."
Challenger slapped his colleague good-humouredly upon the shoulder. "We progress," said he. "Decidedly we progress."
"And pray, sir," asked Summerlee humbly, "what is your opinion as to the present outlook?"
"With your permission I will say a few words upon that subject." He seated himself upon his desk, his short, stumpy legs swinging in front of him. "We are assisting at a tremendous and awful function. It is, in my opinion, the end of the world."
The end of the world! Our eyes turned to the great bow-window and we looked out at the summer beauty of the countryside, the long slopes of heather, the great country-houses, the cozy farms, the pleasure-seekers upon the links.
The end of the world! One had often heard the words, but the idea that they could ever have an immediate practical significance, that it should not be at some vague date, but now, to-day, that was a tremendous, a staggering thought. We were all struck solemn and waited in silence for Challenger to continue. His overpowering presence and appearance lent such force to the solemnity of his words that for a moment all the crudities and absurdities of the man vanished, and he loomed before us as something majestic and beyond the range of ordinary humanity. Then to me, at least, there came back the cheering recollection of how twice since we had entered the room he had roared with laughter. Surely, I thought, there are limits to mental detachment. The crisis cannot be so great or so pressing after all.
`You will conceive a bunch of grapes," said he, "which are covered by some infinitesimal but noxious bacillus. The gardener passes it through a disinfecting medium. It may be that he desires his grapes to be cleaner. It may be that he needs space to breed some fresh bacillus less noxious than the last. He dips it into the poison and they are gone. Our Gardener is, in my opinion, about to dip the solar system, and the human bacillus, the little mortal vibrio which twisted and wriggled upon the outer rind of the earth, will in an instant be sterilized out of existence."
Again there was silence. It was broken by the high trill of the telephone-bell.
"There is one of our bacilli squeaking for help," said he with a grim smile. "They are beginning to realize that their continued existence is not really one of the necessities of the universe."
He was gone from the room for a minute or two. I remember that none of us spoke in his absence. The situation seemed beyond all words or comments.
"The medical officer of health for Brighton," said he when he returned. "The symptoms are for some reason developing more rapidly upon the sea level. Our seven hundred feet of elevation give us an advantage. Folk seem to have learned that I am the first authority upon the question. No doubt it comes from my letter in the Times. That was the mayor of a provincial town with whom I talked when we first arrived. You may have heard me upon the telephone. He seemed to put an entirely inflated value upon his own life. I helped him to readjust his ideas."
