"What do you think of that?" she asked.

Paul did not care to reply. Albert wished to speak, but he stopped at a gesture from his father. Monsieur Dalize knew that the real interest of this scene lay with Monsieur Roger, the scientist, who was already loved by all this little world. Miette, as nobody else answered, returned to Monsieur Roger.

"But why," she asked, "is that physical science? Why is it chemistry?"

"Because it is physical science and chemistry," said Monsieur Roger, simply.

"Oh, but you have other reasons to give us!" said Madame Dalize, who understood what Monsieur Roger was thinking of.

"Yes," added Miette.

And even Paul, with unusual curiosity, nodded his head affirmatively.

"The reasons will be very long to explain, and would bore you," said Monsieur Dalize, certain that he would in this way provoke a protest.

The protest, in fact, came.

Monsieur Roger was obliged to speak.
