“You must leave us or we must leave you,” she said. “If I were your only child, I should do as my mother did, without murmuring against my fate; but my brothers and sister shall not perish beside you with hunger and despair. I promised it to her who died there,” she said, pointing to the place where her mother’s bed had stood. “We have hidden our troubles from you; we have suffered in silence; our strength is gone. My father, we are not on the edge of an abyss, we are at the bottom of it. Courage is not sufficient to drag us out of it; our efforts must not be incessantly brought to nought by the caprices of a passion.” “My dear children,” cried Balthazar, seizing Marguerite’s hand, “I will help you, I will work, I--” “Here is the means,” she answered, showing him the official letter. “But, my darling, the means you offer me are too slow; you make me lose the fruits of ten years’ work, and the enormous sums of money which my laboratory represents. There,” he said, pointing towards the garret, “are our real resources.” Marguerite walked towards the door, saying:-- “Father, you must choose.” “Ah! my daughter, you are very hard,” he replied, sitting down in an armchair and allowing her to leave him. The next morning, on coming downstairs, Marguerite learned from Lemulquinier that Monsieur Claes had gone out. This simple announcement turned her pale; her face was so painfully significant that the old valet remarked hastily:-- “Don’t be troubled, mademoiselle; monsieur said he would be back at eleven o’clock to breakfast. He didn’t go to bed all night. At two in the morning he was still standing in the parlor, looking through the window at the laboratory. I was waiting up in the kitchen; I saw him; he wept; he is in trouble. Here’s the famous month of July when the sun is able to enrich us all, and if you only would--” “Enough,” said Marguerite, divining the thoughts that must have assailed her father’s mind. A phenomenon which often takes possession of persons leading sedentary lives had seized upon Balthazar; his life depended, so to speak, on the places with which it was identified; his thought was so wedded to his laboratory and to the house he lived in that both were indispensable to him,--just as the Bourse becomes a necessity to a stock-gambler, to whom the public holidays are so much lost time. Here were his hopes; here the heavens contained the only atmosphere in which his lungs could breathe the breath of life. This alliance of places and things with men, which is so powerful in feeble natures, becomes almost tyrannical in men of science and students. To leave his house was, for Balthazar, to renounce Science, to abandon the Problem,--it was death.
