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 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 fifty feet up in the air, on the roofs and upper stories of high houses and on 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 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 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.

The car had gone, but it had left a slight ripple ripple which flowed through glove shops and hat shops and tailors’ shops on both sides of Bond Street. For thirty seconds all heads were inclined the same way—to the window. Choosing a pair of gloves—should they be to the elbow or above it, lemon or pale grey?—ladies stopped; when the sentence was finished something had happened. Something so trifling in single instances that no mathematical instrument, though capable of transmitting shocks in China, could register the vibration; yet in its fulness rather formidable and in its common appeal emotional; for in all the hat shops and tailors’ shops strangers looked at each other and thought of the dead; of the flag; of Empire. In a public house in a back street a a Colonial insulted the House of Windsor which led to words, broken beer glasses, and a general shindy, which echoed strangely across the way in the ears of girls buying white underlinen threaded with pure white ribbon for their weddings. For the surface agitation of the passing car as it sunk grazed something very profound.

Gliding across Piccadilly, the car turned down St. James’s Street. Tall men, men of robust physique, well-dressed men with their tail-coats and their white slips and their hair raked back who, for reasons difficult to discriminate, were standing in the bow window of Brooks’s with their hands behind the tails of their coats, looking out, perceived instinctively that greatness was passing, and the pale light of the immortal presence fell upon them as it had fallen upon Clarissa Dalloway. At once they stood even straighter, and removed their hands, and seemed ready to attend their Sovereign, if need be, to the cannon’s mouth, as their ancestors had done before them. The white busts and the little tables in the background covered with copies of the Tatler and syphons of soda water seemed to approve; seemed to indicate the flowing corn and the manor houses of England; and to return the frail hum of the motor wheels as the walls of a whispering gallery return a single voice expanded and made sonorous by the might of a whole cathedral. Shawled Moll Pratt with her flowers on the pavement wished the dear boy well (it was the Prince of Wales for certain) and would have tossed the price of a pot of beer—a bunch of roses—into St. James’s Street out of sheer light-heartedness and contempt of poverty had she not seen the constable’s eye upon her, discouraging an old Irishwoman’s loyalty. The sentries at St. James’s saluted; Queen Alexandra’s policeman approved.

A small crowd meanwhile had gathered at the gates of Buckingham Palace. Listlessly, yet confidently, poor people all of them, they waited; looked at the Palace itself with the flag flying; at Victoria, billowing on her mound, admired her shelves of running water, her geraniums; singled out from the motor cars in the Mall first this one, then that; bestowed emotion, vainly, upon commoners out for a drive; recalled their tribute to keep it unspent while this car passed and that; and all the time let rumour accumulate in their veins and thrill the nerves in their thighs at the thought of Royalty looking at them; the Queen bowing; the Prince saluting; at the thought of the heavenly life divinely bestowed upon Kings; of the equerries and deep curtsies; of the Queen’s old doll’s house; of Princess Mary married to an Englishman, and the Prince—ah! the Prince! who took wonderfully, they said, after old King Edward, but was ever so much slimmer. The Prince lived at St. James’s; but he might come along in the morning to visit his mother.
