"It will be a murder!" he cried vehemently.

Bertheroy waved his hand: "What would you have?" he answered: "there's a
social system and it defends itself when it is attacked. Besides, those
Anarchists are really too foolish in imagining that they will transform
the world with their squibs and crackers! In my opinion, you know,
science is the only revolutionist. Science will not only bring us truth
but justice also, if indeed justice ever be possible on this earth. And
that is why I lead so calm a life and am so tolerant."

Once again Bertheroy appeared to Guillaume as a revolutionist, one who
was convinced that he helped on the ruin of the ancient abominable
society of today, with its dogmas and laws, even whilst he was working in
the depths of his laboratory. He was, however, too desirous of repose,
and had too great a contempt for futilities to mingle with the events of
the day, and he preferred to live in quietude, liberally paid and
rewarded, and at peace with the government whatever it might be, whilst
at the same time foreseeing and preparing for the formidable parturition
of the future.

He waved his hand towards Paris, over which a sun of victory was setting,
and then again spoke: "Do you hear the rumble? It is we who are the
stokers, we who are ever flinging fresh fuel under the boiler. Science
does not pause in her work for a single hour, and she is the artisan of
Paris, which--let us hope it--will be the artisan of the future. All the
rest is of no account."

But Guillaume was no longer listening to him. He was thinking of Salvat
and the terrible engine of war he had invented, that engine which before
long would shatter cities. And a new idea was dawning and growing in his
mind. He had just freed himself of his last tie, he had created all the
happiness he could create around him. Ah! to recover his courage, to be
master of himself once more, and, at any rate, derive from the sacrifice
of his heart the lofty delight of being free, of being able to lay down
even his life, should he some day deem it necessary!

I. THE GUILLOTINE

FOR some reason of his own Guillaume was bent upon witnessing the
execution of Salvat. Pierre tried to dissuade him from doing so; and
finding his efforts vain, became somewhat anxious. He accordingly
resolved to spend the night at Montmartre, accompany his brother and
watch over him. In former times, when engaged with Abbe Rose in
charitable work in th
