Before dawn the black vapour was pouring through the streets of Richmond, and the disintegrating organism of government was, with a last expiring effort, rousing the population of London to the necessity of flight.
They were sparing of the Heat-Ray that night, either because they had but a limited supply of material for its production or because they did not wish to destroy the country but only to crush and overawe the opposition they had aroused. In the latter aim they certainly succeeded. Sunday night was the end of the organized opposition to their movements. After that no body of men would stand against them, so hopeless was the enterprise. Even the crews of the torpedo-boats and destroyers that had brought their quick-firers up the Thames refused to stop, mutinied, and went down again. The only offensive operation men ventured upon after that night was the preparation of mines and pitfalls, and even in that their energies were frantic and spasmodic.
One may picture, too, the sudden shifting of the attention, the swiftly spreading coils and bellyings of that blackness advancing headlong, towering heavenward, turning the twilight to a palpable darkness, a strange and horrible antagonist of vapour striding upon its victims, men and horses near it seen dimly, running, shrieking, falling headlong, shouts of dismay, the guns suddenly abandoned, men choking and writhing on the ground, and the swift broadening-out of the opaque cone of smoke. And then night and extinction–nothing but a silent mass of impenetrable vapour hiding its dead.
