The Time Traveller (for so it will be convenient to speak of him) was expounding a recondite matter to us. His grey eyes shone and twinkled, and his usually pale face was flushed and animated. The fire burned brightly, and the soft radiance of the incandescent lights in the lilies of silver caught the bubbles that flashed and passed in our glasses. Our chairs, being his patents, embraced and caressed us rather than submitted to be sat upon, and there was that luxurious after-dinner atmosphere when thought roams gracefully free of the trammels of precision. And he put it to us in this way—marking the points with a lean forefinger—as we sat and lazily admired his earnestness over this new paradox (as we thought it:) and his fecundity.

‘You must follow me carefully. I shall have to controvert one or two ideas that are almost universally accepted. The geometry, for instance, they taught you at school is founded on a misconception.’

‘Is not that rather a large thing to expect us to begin upon?’ said Filby, an argumentative person with red hair.

‘I do not mean to ask you to accept anything without reasonable ground for it. You will soon admit as much as I need from you. You know of course that a mathematical line, a line of thickness NIL, has no real existence. They taught you you that? Neither has a mathematical plane. These things are mere abstractions.’

‘That is all right,’ said the Psychologist.

‘Nor, having only length, breadth, and thickness, can a cube have a real existence.’

‘There I object,’ said Filby. ‘Of course a solid body may exist. All real things—’

‘So most people think. But wait a moment. Can an INSTANTANEOUS cube exist?’

‘Don’t follow you,’ said Filby.

‘Can a cube that does not last for any time at all, have a real existence?’

Filby became pensive. ‘Clearly,’ the Time Traveller proceeded, ‘any real body must have extension in FOUR directions: it must have Length, Breadth, Thickness, and—Duration. But through a natural infirmity of the flesh, which I will explain to you in a moment, we incline to overlook this fact. There are really four dimensions, three which we call the three planes of Space, and a fourth, Time. There is, however, a tendency to draw an unreal distinction between the former three dimensions and the latter, because it happens that our consciousness moves intermittently in one direction along the latter from the beginning to the end of our lives.’

‘That,’ said a very young man, making spasmodic efforts to relight his cigar over the lamp; ‘that . . . very clear indeed.’

‘Now, it is very remarkable that this is so extensively overlooked,’ continued the Time Traveller, with a slight accession of cheerfulness. ‘Really this is what is meant by the Fourth Dimension, though some people who talk about the Fourth Dimension do not know they mean it. It is only another way of looking at Time. THERE IS NO DIFFERENCE BETWEEN TIME AND ANY OF THE THREE DIMENSIONS OF SPACE EXCEPT THAT OUR CONSCIOUSNESS MOVES ALONG IT. But some foolish people have got hold of the wrong side of that idea. You have all heard what they have to say about this Fourth Dimension?’

“The man that lives there,” said I.

“James of the Glens,” says Glenure, musingly; and then to the lawyer: “Is he gathering his people, think ye?”

“Anyway,” says the lawyer, “we shall do better to bide where we are, and let the soldiers rally us.”

“If you are concerned for me,” said I, “I am neither of his people nor yours, but an honest subject of King George, owing no man and fearing no man.”

“Why, very well said,” replies the Factor. “But if I may make so bold as ask, what does this honest man so far from his country? and why does he come seeking the brother of Ardshiel? I have power here, I must tell you. I am King’s Factor upon several of these estates, and have twelve files of soldiers at my back.”

“I have heard a waif word in the country,” said I, a little nettled, “that you were a hard man to drive.”

He still kept looking at me, as if in doubt.

“Well,” said he, at last, “your tongue is bold; but I am no unfriend to plainness. If ye had asked me the way to the door of James Stewart on any other day but this, I would have set ye right and bidden ye God speed. But to–day — eh, Mungo?” And he turned again to look at the lawyer.

But just as he turned there came the shot of a firelock from higher up the hill; and with the very sound of it Glenure fell upon the road.

“O, I am dead!” he cried, several times over.

The lawyer had caught him up and held him in his arms, the servant standing over and clasping his hands. And now the wounded man looked from one to another with scared eyes, and there was a change in his voice, that went to the heart.

“Take care of yourselves,” says he. “I am dead.”

He tried to open his clothes as if to look for the wound, but his fingers slipped on the buttons. With that he gave a great sigh, his head rolled on his shoulder, and he passed away.

The lawyer said never a word, but his face was as sharp as a pen and as white as the dead man’s; the servant broke out into a great noise of crying and weeping, like a child; and I, on my side, stood staring at them in a kind of horror. The sheriff’s officer had run back at the first sound of the shot, to hasten the coming of the soldiers.

At last the lawyer laid down the dead man in his blood upon the road, and got to his own feet with a kind of stagger.

I believe it was his movement that brought me to my senses; for he had no sooner done so than I began to scramble up the hill, crying out, “The murderer! the murderer!”

So little a time had elapsed, that when I got to the top of the first steepness, and could see some part of the open mountain, the murderer was still moving away at no great distance. He was a big man, in a black coat, with metal buttons, and carried a long fowling–piece.

“Here!” I cried. “I see him!”

At that the murderer gave a little, quick look over his shoulder, and began to run. The next moment he was lost in a fringe of birches; then he came out again on the upper side, where I could see him climbing like a jackanapes, for that part was again very steep; and then he dipped behind a shoulder, and I saw him no more.
