Mabœuf had not entirely lost his childlike serenity; his eye acquired some vivacity when it settled on his books, and he smiled when he regarded the Diogenes Laertius, which was a unique copy. His glass case was the only furniture which he had retained beyond what was indispensable. One day Mother Plutarch said to him,-- "I have no money to buy dinner with." What she called dinner consisted of a loaf and four or five potatoes. "Can't you get it on credit?" said M. Mabœuf. "You know very well that it is refused me." M. Mabœuf opened his bookcase, looked for a long time at all his books in turn, as a father, obliged to decimate his children, would look at them before selecting, then took one up quickly, put it under his arm, and went out. He returned two hours after with nothing under his arm, laid thirty sous on the table, and said,-- "You will get some dinner." From this moment Mother Plutarch saw a dark veil, which was not raised again, settle upon the old gentleman's candid face. The next day, the next after that, and every day, M. Mabœuf had to begin again; he went out with a book and returned with a piece of silver. As the second-hand booksellers saw that he was compelled to sell, they bought for twenty sous books for which he had paid twenty francs, and frequently to the same dealers. Volume by volume his whole library passed away, and he said at times, "And yet I am eighty years of age," as if he had some lurking hope that he should reach the end of his days ere he reached the end of his books. His sorrow grew, but once he had a joy: he went out with a Robert Estienne, which he sold for thirty-five sous on the Quai Malaquais, and came home with an Aldus which he had bought for forty sous in the Rue de Grès. "I owe five sous," he said quite radiantly to Mother Plutarch, but that day he did not dine. He belonged to the Horticultural Society, and his poverty was known. The President of the Society called on him, promised to speak about him to the Minister of Commerce and Agriculture, and did so. "What do you say?" the minister exclaimed. "I should think so! an old savant! a botanist! an inoffensive man! we must do something for him." The next day M. Mabœuf received an invitation to dine with the minister, and, trembling with joy, showed the letter to Mother Plutarch. "We are saved!" he said. On the appointed day he went to the minister's, and noticed that his ragged cravat, his long, square-cut coat, and shoes varnished with white of egg, astounded the footman. No one spoke to him, not even the minister, and at about ten in the evening, while still waiting for a word, he heard the minister's wife, a handsome lady in a low-necked dress, whom he had not dared to approach, ask, "Who can that old gentleman be?" He went home afoot at midnight through the pouring rain; he had sold an Elzevir to pay his hackney coach in going.
