But the knife fell with a dull, heavy, forcible thud, and two long jets of blood spurted from the severed arteries, while the dead man's feet moved convulsively.

Nothing else could be seen.

The executioner rubbed his hands in a mechanical way, and an assistant took the severed blood-streaming head from the little basket into which it had fallen and placed it in the large basket into which the body had already been turned.
Ah! that dull, that heavy thud of the knife! It seemed to Guillaume that he had heard it echoing far away all over that district of want and toil, even in the squalid rooms where thousands of workmen were at that moment rising to perform their day's hard task! And there the echo of that thud acquired formidable significance; it spoke of man's exasperation with injustice, of zeal for martyrdom, and of the dolorous hope that the blood then spilt might hasten the victory of the disinherited.
Pierre, for his part, at the sight of that loathsome butchery, the abject cutthroat work of that killing machine, had suddenly felt his chilling shudder become more violent; for before him arose a vision of another corpse, that of the fair, pretty child ripped open by a bomb and stretched yonder, at the entrance of the Duvillard mansion.

Blood streamed from her delicate flesh, just as it had streamed from that decapitated neck.

It was blood paying for blood; it was like payment for mankind's debt of wretchedness, for which payment is everlastingly being made, without man ever being able to free himself from suffering.
Above the square and the crowd all was still silent in the clear sky.
