Her father had no sooner recommenced his experiments than Marguerite retrenched the superfluities of the table, showing a parsimony worthy of a miser, in which Josette and Martha admirably seconded her. Claes never noticed the change which reduced the household living to the merest necessaries. First he ceased to breakfast with the family; then he only left his laboratory when dinner was ready; and at last, before he went to bed, he would sit some hours in the parlor between his daughters without saying a word to either of them; when he rose to go upstairs they wished him good-night, and he allowed them mechanically to kiss him on both cheeks. Such conduct would have led to great domestic misfortunes had Marguerite not been prepared to exercise the authority of a mother, and if, moreover, she were not protected by a secret love from the dangers of so much liberty. Pierquin had ceased to come to the house, judging that the family ruin would soon be complete. Balthazar’s rural estates, which yielded sixteen thousand francs a year, and were worth about six hundred thousand, were now encumbered by mortgages to the amount of three hundred thousand francs; for, in order to recommence his researches, Claes had borrowed a considerable sum of money. The rents were exactly enough to pay the interest of the mortgages; but, with the improvidence of a man who is the slave of an idea, he made over the income of his farm lands to Marguerite for the expenses of the household, and the notary calculated that three years would suffice to bring matters to a crisis, when the law would step in and eat up all that Balthazar had not squandered. Marguerite’s coldness brought Pierquin to a state of almost hostile indifference. To give himself an appearance in the eyes of the world of having renounced her hand, he frequently remarked of the Claes family in a tone of compassion:-- “Those poor people are ruined; I have done my best to save them. Well, it can’t be helped; Mademoiselle Claes refused to employ the legal means which might have rescued them from poverty.”
