a of revolutionising the world."

But Bertheroy protested. This great official scientist, this member of
the Institute laden with offices and honours, pointed to the little
motor, and replied with all the vigour of his seventy years: "But that is
revolution, the true, the only revolution. It is with things like that
and not with stupid bombs that one revolutionises the world! It is not by
destroying, but by creating, that you have just done the work of a
revolutionist. And how many times already have I not told you that
science alone is the world's revolutionary force, the only force which,
far above all paltry political incidents, the vain agitation of despots,
priests, sectarians and ambitious people of all kinds, works for the
benefit of those who will come after us, and prepares the triumph of
truth, justice and peace.... Ah, my dear child, if you wish to
overturn the world by striving to set a little more happiness in it, you
have only to remain in your laboratory here, for human happiness can
spring only from the furnace of the scientist."

He spoke perhaps in a somewhat jesting way, but one could feel that he
was convinced of it all, that he held everything excepting science in
utter contempt. He had not even shown any surprise when Pierre had cast
his cassock aside; and on finding him there with his wife and child he

Meantime, however, the motor was travelling hither and thither, making no
more noise than a bluebottle buzzing in the sunshine. The whole happy
family was gathered about it, still laughing with delight at such a
victorious achievement. And all at once little Jean, Monsieur Jean,
having finished sucking, turned round, displaying his milk-smeared lips,
and perceived the machine, the pretty plaything which walked about by
itself. At sight of it, his eyes sparkled, dimples appeared on his plump
cheeks, and, stretching out his quivering chubby hands, he raised a crow
of delight.

Marie, who was quietly fastening her dress, smiled at his glee and
brought him nearer, in order that he might have a better view of the toy.
"Ah! my darling, it's pretty, isn't it? It moves and it turns, and it's
strong; it's quite alive, you see."

The others, standing around, were much amused by the amazed, enraptured
expression of the child, who would have liked to touch the machine,
perhaps in the hope of understanding it.

"Yes," resumed Bertheroy, "it's
