"No, sir, I will not repent. I promise you that."
"Very well," said Miette; "there is another promise. You know that you will have to keep it."
"But," answered Monsieur Roger, turning to Paul, "it will be necessary for me to speak to you of weight, of the fall of bodies, of gravitation; and I am very much afraid that that will weary you."
"No, sir," answered Paul, very seriously, "that will not weary me. On the contrary, that will interest me, if it teaches me how you managed to calculate the height of the tower."
"It will certainly teach you that."
"Then I am content," said Paul.
"And I also," said Monsieur Roger to himself, happy to have attained his object so soon.
