had doubtless found
him worthy of admission into it, though she did not reveal the reason
why. After days and days of silence she had simply said, one evening, to
Guillaume, that he had done well in bringing his brother to live among
them.

Time flew by as she sat sewing and thinking. Towards noon Guillaume, who
was still at work, suddenly remarked to her: "As Marie and Pierre haven't
come back, we had better let the lunch wait a little while. Besides, I
should like to finish what I'm about."

Another quarter of an hour then elapsed. Finally, the three young men
rose from their work, and went to wash their hands at a tap in the
garden.

"Marie is very late," now remarked Mere-Grand. "We must hope that nothing
has happened to her."

"Oh! she rides so well," replied Guillaume. "I'm more anxious on account
of Pierre."

At this the old lady again fixed her eyes on him, and said: "But Marie

"No doubt; still I should be better pleased if they were back home."

Then all at once, fancying that he heard the ring of a bicycle bell, he
called out: "There they are!" And forgetting everything else in his
satisfaction, he quitted his furnace and hastened into the garden in
order to meet them.

Mere-Grand, left to herself, quietly continued sewing, without a thought

apparatus near her. A couple of minutes later, however, when Guillaume
came back, saying that he had made a mistake, his eyes suddenly rested on
his furnace, and he turned quite livid. Brief as had been his absence the
exact moment when it was necessary to turn off a tap in order that no
danger might attend the preparation of his powder had already gone by;
and now, unless someone should dare to approach that terrible tap, and
boldly turn it, a fearful explosion might take place. Doubtless it was
too late already, and whoever might have the bravery to attempt the feat
would be blown to pieces.

Guillaume himself had often run a similar risk of death with perfect
composure. But on this occasion he remained as if rooted to the floor,
unable to take a step, paralysed by the dread of annihilation. He
shuddered and stammered in momentary expectation of a catastrophe which
would hurl the work-shop to the heavens.

"Mere-Grand, Mere-Grand," he stammered. "The apparatus, the tap... it
is all over, all over!"

The old woman had rais
