Time went on, and fresh debts hammered at the door of the Maison Claes. At last Marguerite was obliged to face her father, and charge him with madness.

"Madness!" he cried, firing up and springing to his feet. There was something so majestic and commanding in his attitude that made Marguerite tremble at his feet. "Your mother would never have used that word; she always attached due importance to my scientific researches."

She could not bear his reproaches, and fled from him. She felt that the time had come, for they were now on the verge of beggary, to break the seal of her mother's letter. That letter expressed the most divine love, praying that God would permit her spirit to be with Marguerite while she read the words of this last message; and it told her that the Abbé Solis, if living, or his nephew, held for her a sum of a hundred and seventy thousand francs, and on this sum she must live, and leave her father if he refused to abandon his researches. "I could never have said these words," Josephine had written; "not even on the brink of the grave." And she entreated her child to be reverent in withstanding her father, and if resistance was inevitable to resist him on her knees. The abbé was dead, but Emmanuel held the money. In their discussions about the management of this sum, the two young people drew closer together. The poor father, brought to ruin, confessed his madness, and uttered the terrible despair of a beaten scientist. To comfort him, Marguerite said that his debts would be paid with her money. His face lit up. "You have money! Give it to me; I will make you rich." Once more the madness returned.

Emmanuel came with three thousand ducats in his pockets. They were hiding them in the hollow column of a pedestal, when, looking up, Marguerite saw her father observing them. "I heard gold," he said, advancing. To save her, Emmanuel lied. He sinned against his conscience for her sake. The money, he said belonged to him, and he had lent it to Marguerite. When he was gone, Claes said: "I must have that money."

"If you take it," answered Marguerite, "you will be a thief."

He knelt to her; she would not relent. He caressed her; she called God to look down upon them if he stole the money. He rose, bade her a sorrowful farewell, and left the room. Something warned her; she hurried after him, to find him with a pistol at his head. "Take all I possess," she cried. Embracing her, he promised that if he failed this time he would deliver himself into her hands.

Time passed and the Absolute was not discovered. A wealthy cousin of Claes, M. Conyncks, came to Douai in his travelling carriage, and soon after he and Marguerite journeyed to Paris. When she returned, it was to announce that, through M. Conynck's influence, Balthazar had been appointed receiver of taxes in Brittany, and must set out at once to take up the appointment.

"You drive me out of my own house!" he exclaimed, with anger. At first he refused to go, furious and indignant; but she persisted, and he had to surrender. He went with Lemulquinier to his laboratory for the last time. The two old men were very sad as they released the gases and evaporated acids.

"Ah, look," said Claes, pausing before a capsule connected with the wires of a battery; "if only we could watch out the end of this experiment! Carbon and sulphur. Crystallisation should take place; the carbon might certainly result in a crystal ..."

While Claes was in exile, fortune came to the family. The son Gabriel, assisted by M. Conyncks, had made a large sum of money as the engineer of a canal. Emmanuel de Solis had given Marguerite the fortune he inherited from ancestors in Spain. Pierquin, who had turned his attention to Marguerite's younger sister, had proved himself kind to the family. Once again the Maison Claes was in prosperity, with pictures on its walls, and with handsome furniture in its state apartments.
