there rose above the ilexes what might have been a greater ilex; there was the blackness of a dense growth of foliage rising like a broad and far-spreading and rounded cloud over the lesser trees.
Here, then, was a sight wholly incredible, impossible. It is doubtful whether the process of the human mind in such a case has ever been analysed and registered; it is doubtful whether it ever can be registered. It is hardly fair to bring in the mathematician, since he deals with absolute truth (so far as mortality can conceive absolute truth); but how would a mathematician feel if he were suddenly confronted with a two-sided triangle? I suppose he would instantly become a raging madman; and Lewis, staring wide-eyed and wild-eyed at a dark and spreading tree which his own experience informed him was not there, felt for an instant that shock which should affront us all when we first realize the intolerable antinomy of Achilles and the tortoise.
Common sense tells us that Achilles will flash past the tortoise almost with the speed of the lightning; the inflexible truth of mathematics assures us that till the earth boils and the heavens cease to endure, the tortoise must still be in advance; and thereupon we should, in common decency, go mad. We do not go mad, because, by special grace, we are certified that, in the final court of appeal, all science is a lie, even the highest science of all; and so we simply grin at Achilles and the tortoise, as we grin at Darwin, deride Huxley, and laugh at Herbert Spencer.
Dr. Lewis did not grin. He glared into the dimness of the night, at the great spreading tree that he knew could not be there. And as he gazed he saw that what at first appeared the dense blackness of foliage was fretted and starred with wonderful appearances of lights and colours.
Afterwards he said to me: 'I remember thinking to myself: Look here, I am not delirious; my temperature is perfectly normal. I am not drunk; I only had a pint of Graves with my dinner, over three hours ago. I have not eaten any poisonous fungus; I have not taken
The night had gloomed over; clouds obscured the faint moon and the misty stars. Lewis rose, with some kind of warning and inhibiting gesture to Remnant, who, he was conscious was gaping at him in astonishment. He walked to the open French window, and took a pace forward on the path outside, and looked, very intently, at a dark shape of the tree, down below the sloping garden, above the washing of the waves. He shaded the light of the lamp behind him by holding his hands on each side of his eyes.
The mass of the tree—the tree that couldn't be there—stood out against the sky, but not so clearly, now that the clouds had rolled up. Its edges, the limits of its leafage, were not so distinct.
Lewis thought that he could detect some sort of quivering movement in it; though the air was at a dead calm. It was a night on which one might hold up a lighted match and watch it burn without any wavering or inclination of the flame.
'You know,' said Lewis, 'how a bit of burnt paper will sometimes hang over the coals before it goes up the chimney, and little worms of fire will shoot through it. It was like that, if you should be standing some distance away. Just threads and hairs of yellow light I saw, and specks and sparks of fire, and then a twinkling of a ruby no bigger than a pin point, and a green wandering in the black, as if an emerald were crawling, and then little veins of deep blue. 'Woe is me!' I said to myself in Welsh, 'What is all this color and burning?' And, then, at that very moment there came a thundering rap at the door of the room inside, and there was my man telling me that I was wanted directly up at the Garth, as old Mr. Trevor Williams had been taken very bad. I knew his heart was not worth much, so I had to go off directly and leave Remnant to make what he could of it all.'
Chapter 6 Mr. Remnant's Ray
Dr. Lewis was kept some time at the Garth. It was past twelve when he got back to his house. He went quickly to the room that overlooked the garden and the sea and threw open the French window and peered into the darkness. There, dim indeed against the dim sky but unmistakable, was the tall pine with its sparse branches, high above the dense growth of the ilex-trees. The strange boughs which had amazed him had vanished; there was no appearance now of colours or of fires.
He drew his chair up to the open window and sat there gazing and wondering far into the night, till brightness came upon the sea and sky, and the forms of the trees in the garden grew clear and evident.
He went up to his bed at last filled with a great perplexity, still asking questions to which there was no answer.
The doctor did not say anything about the strange tree to Remnant. When they next met, Lewis said that he had thought there was a man hiding amongst the bushes—this in explanation of that warning gesture he had used, and of his going out into the garden and staring into the night. He concealed the truth because he dreaded the Remnant doctrine that would undoubtedly be produced; indeed, he hoped that he had heard the last of the theory of the Z ray. But Remnant firmly reopened this subject.
'We were interrupted just as I was putting my case to you,' he said. 'And to sum it all up, it amounts to this: that the Huns have made one of the great leaps of science. They are sending 'suggestions' (which amount to irresistible commands) over here, and the persons affected are seized with suicidal or homicidal mania. The people who were killed by falling over the cliffs or into the quarry probably committed suicide; and so with the man and boy who were found in the bog. As to the Highway case, you remember that Thomas Evans said that he stopped and talked to Williams on the night of the murder. In my opinion Evans was the murderer. He came under the influence of the ray, became a homicidal maniac in an instant, snatched Williams's spade from his hand and killed him and the others.'
'The bodies were found by me on the road.'
'It is possible that the first impact of the ray produces violent nervous excitement, which would manifest itself externally. Williams might have called to his wife to come and see what was the matter with Evans. The children would naturally follow their mother. It seems to me simple. And as for the animals—the homes, dogs, and so forth, they as I say, were no doubt panic-stricken by the ray, and hence driven to frenzy.'
'Why should Evans have murdered Williams instead of Williams murdering Evans? Why should the impact of the ray affect one and not the other?'
'Why does one man react violently to a certain drug, while it makes no impression on another man? Why is A able to drink a bottle of whisky and remain sober, while B is turned into something very like a lunatic after he has drunk three glasses?'
'It is a question of idiosyncrasy,' said the doctor.
'Is 'idiosyncrasy' Greek for 'I don't know'?' asked Remnant.
'Not at all,' said Lewis, smiling blandly. 'I mean that in some diatheses whisky—as you have mentioned whisky—appears not to be pathogenic, or at all events not immediately pathogenic. In other cases, as you very justly observed, there seems to be a very marked cachexia associated with the exhibition of the spirit in question, even in comparatively small doses.'
Under this cloud of professional verbiage Lewis escaped from the club and from Remnant. He did not want to hear any more about that dreadful ray, because he felt sure that the ray was all nonsense. But asking himself why he felt this certitude in the matter, he had to confess that he didn't know. An aeroplane, he reflected, was all nonsense before it was made; and he remembered talking in the early nineties to a friend of his about the newly discovered X rays.
The friend laughed incredulously, evidently didn't believe a word of it, till Lewis told him that there was an article on the subject in the current number of the Saturday Review; whereupon the unbeliever said, 'Oh, is that so? Oh, really. I see,' and was converted on the X ray faith on the spot. Lewis, remembering this talk, marvelled at the strange processes of the human mind, its illogical and yet all-compelling ergos, and wondered whether he himself was only waiting for an article on the Z ray in the Saturday Review to become a devout believer in the doctrine of Remnant.
But he wondered with far more fervor as to the extraordinary thing he had seen in his own garden with his own eyes. The tree that changed all its shape for an hour or two of the night, the growth of strange boughs, the apparition of secret fires among them, the sparkling of emerald and ruby lights: how could one fail to be afraid with great amazement at the thought of such a mystery?
Dr. Lewis's thoughts were distracted from the incredible adventure of the tree by the visit of his sister and her husband. Mr. and Mrs. Merritt lived in a well-known manufacturing town of the Midlands, which was now, of
