The catalytic wave must have caught the place in full swing, in its nocturnal high fever, indeed in a quite exceptional state of fever, what with the comet and the war, and more particularly with the war. Very probably the Change crept into the office imperceptibly, amidst the noise and shouting, and the glare of electric light that made the night atmosphere in that place; even the green flashes may have passed unobserved there, the preliminary descending trails of green vapor seemed no more than unseasonable drifting wisps of London fog. (In those days London even in summer was not safe against dark fogs.) And then at the last the Change poured in and overtook them.
If there was any warning at all for them, it must have been a sudden universal tumult in the street, and then a much more universal quiet. They could have had no other intimation.
There was no time to stop the presses before the main development of green vapor had overwhelmed every one. It must have folded about them, tumbled them to the earth, masked and stilled them. My imagination is always curiously stirred by the thought of that, because I suppose it is the first picture I succeeded in making for myself of what had happened in the towns. It has never quite lost its strangeness for me that when the Change came, machinery went on working. I don’t precisely know why that should have seemed so strange to me, but it did, and still to a certain extent does. One is so accustomed, I suppose, to regard machinery as an extension of human personality that the extent of its autonomy the Change displayed came as a shock to me. The electric lights, for example, hazy green-haloed nebulas, must have gone on burning at least for a time; amidst the thickening darkness the huge presses must have roared on, printing, folding, throwing aside copy after copy of that fabricated battle report with its quarter column of scare headlines, and all the place must have still quivered and throbbed with the familiar roar of the engines. And this though no men ruled there at all any more! Here and there beneath that thickening fog the crumpled or outstretched forms of men lay still.
A wonderful thing that must have seemed, had any man had by chance the power of resistance to the vapor, and could he have walked amidst it.
