It was heavy, this vapour, heavier than the densest smoke, so that, after the first tumultuous uprush and outflow of its impact, it sank down through the air and poured over the ground in a manner rather liquid than gaseous, abandoning the hills, and streaming into the valleys and ditches and watercourses even as I have heard the carbonic-acid gas that pours from volcanic clefts is wont to do. And where it came upon water some chemical action occurred, and the surface would be instantly covered with a powdery scum that sank slowly and made way for more. The scum was absolutely insoluble, and it is a strange thing, seeing the instant effect of the gas, that one could drink without hurt the water from which it had been strained. The vapour did not diffuse as a true gas would do. It hung together in banks, flowing slug- gishly down the slope of the land and driving reluctantly before the wind, and very slowly it combined with the mist and moisture of the air, and sank to the earth in the form of dust. Save that an unknown element giving a group of four lines in the blue of the spectrum is concerned, we are still entirely ignorant of the nature of this substance.

Once the tumultuous upheaval of its dispersion was over, the black smoke clung so closely to the ground, even before its precipitation, that fifty feet up in the air, on the roofs and upper stories of high houses and on great great trees, there was a chance of escaping its poison altogether, as was proved even that night at Street Cobham and Ditton.

The man who escaped at the former place tells a wonderful story of the strangeness of its coiling flow, and how he looked down from the church spire and saw the houses of the village rising like ghosts out of its inky nothingness. For a day and a half he remained there, weary, starving and sun-scorched, the earth under the blue sky and against the prospect of the distant hills a velvet-black expanse, with red roofs, green trees, and, later, black-veiled shrubs and gates, barns, out- houses, and walls, rising here and there into the sunlight.

But that was at Street Cobham, where the black vapour was allowed to remain until it sank of its own accord into the ground. As a rule the Martians, when it had served its purpose, cleared the air of it again by wading into it and directing a jet of steam upon it.

This they did with the vapour banks near us, as we saw in the starlight from the window of a deserted house at Upper Halliford, whither we had returned. From there we could see the searchlights on Richmond Hill and Kingston Hill going to and fro, and about eleven the windows rattled, and we heard the sound of the huge siege guns that had been put in position there. These continued intermittently for the space of a quarter of an hour, sending chance shots at the invisible Martians at Hampton and Ditton, and then the pale beams of the electric light vanished, and were replaced by a bright red glow.

Then the fourth cylinder fell--a brilliant green meteor--as I learned afterwards, in Bushey Park. Before the guns on the Richmond and Kingston line of hills began, there was a fitful cannonade far away in the southwest, due, I believe, to guns being fired haphazard before the black vapour could over- whelm the gunners.

And then Lady Lovejoy stiffened. “Lady and Miss Lovejoy,” she said to Mr. Wilkins (hired for parties). He had an admirable manner, as he bent and straightened himself, bent and straightened himself and announced with perfect impartiality “Lady and Miss Lovejoy . . . Sir John and Lady Needham . . . Miss Weld . . . Mr. Walsh.” His manner was admirable; his family life must be irreproachable, except that it seemed impossible that a being with greenish lips and shaven cheeks could ever have blundered into the nuisance of children.

“How delightful to see you!” said Clarissa. She said it to every one. How delightful to see you! She was at her worst—effusive, insincere. It was a great mistake to have come. He should have stayed at home and read his book, thought Peter Walsh; should have gone to a music hall; he should have stayed at home, for he knew no one.

Oh dear, it was going to be a failure; a complete failure, Clarissa felt it in her bones as dear old Lord Lexham stood there apologising for his wife who had caught cold at the Buckingham Palace garden party. She could see Peter out of the tail of her eye, criticising her, there, in that corner. Why, after all, did she do these things? Why seek pinnacles and stand drenched in fire? Might it consume her anyhow! Burn her to cinders! Better anything, better brandish one’s torch and hurl it to earth than taper and dwindle away like some Ellie Henderson! It was extraordinary how Peter put her into these states just by coming and standing in a corner. He made her see herself; exaggerate. It was idiotic. But why did he come, then, merely to criticise? Why always take, never give? Why not risk one’s one little point of view? There he was wandering off, and she must speak to him. But she would not get the chance. Life was that—humiliation, renunciation. What Lord Lexham was saying was that his wife would not wear her furs at the garden party because “my dear, you ladies are all alike”—Lady Lexham being seventy-five at least! It was delicious, how they petted each other, that old couple. She did like old Lord Lexham. She did think it mattered, her party, and it made her feel quite sick to know that it was all going wrong, all falling flat. Anything, any explosion, any horror was better than people wandering aimlessly, standing in a bunch at a corner like Ellie Henderson, not even caring to hold themselves upright.

Gently the yellow curtain with all the birds of Paradise blew out and it seemed as if there were a flight of wings into the room, right out, then sucked back. (For the windows were open.) Was it draughty, Ellie Henderson wondered? She was subject to chills. But it did not matter that she should come down sneezing to-morrow; it was the girls with their naked shoulders she thought of, being trained to think of others by an old father, an invalid, late vicar of Bourton, but he was dead now; and her chills never went to her chest, never. It was the girls she thought of, the young girls with their bare shoulders, she herself having always been a wisp of a creature, with her thin hair and meagre profile; though now, past fifty, there was beginning to shine through some mild beam, something purified into distinction by years of self-abnegation but obscured again, perpetually, by her distressing gentility, her panic fear, which arose from three hundred pounds’ income, and her weaponless state (she could not earn a penny) and it made her timid, and more and more disqualified year by year to meet well-dressed people who did this sort of thing every night of the season, merely telling their maids “I’ll wear so and so,” whereas Ellie Henderson ran out nervously and bought cheap pink flowers, half a dozen, and then threw a shawl over her old black dress. For her invitation to Clarissa’s party had come at the last moment. She was not quite happy about it. She had a sort of feeling that Clarissa had not meant to ask her this year.
