In order to hasten his liberation from debt and his settlement with creditors, Balzac tried to augment the sums which he received from editors and publishers with the profits from various speculations. He expected a rise in value of the shares which he held in the company of the Chemins de Fer du Nord, and, either trusting to reliable information or else himself possessing an intimate knowledge of the development of real estate in Paris, he urged Mme. Hanska to invest her capital in land in the Monceau district. He cited the example of Louis-Philippe, who was the cleverest speculator of his time, and who had acquired tracts of immense extent. After the close of 1846 Balzac retired from the outside world and gave himself up almost entirely to his great work. Through an intermediary he had purchased the residence of the financier, Baujon, in the Rue Fortunee, and with great secrecy he had it repaired and redecorated, with a view to making it habitable at the earliest possible date. Here he deposited his wealth of furnishings,--which had already begun to excite public wonderment, owing to certain indiscreet revelations,--but his life, which had always been closely hidden, had now become practically unknown. He was unwilling to show himself again in public until he could return in triumph after his marriage. Mme. Hanska visited Paris a second time, in 1847, and approved of all his arrangements. Balzac in return went to Wierzchownia that same year, and he was dazzled by the vastness of her estates,--which were equal in extent to a whole department of France,--and by the possibilities of neglected and undeveloped resources which might be made to yield millions. After his return to Paris he had but one desire: to go back to Wierzchownia, celebrate his marriage, and realise the dream which he had tenaciously pursued for seventeen years. He remained in Paris six months, living in his new home in the Rue Fortunee, denying himself to all but his most intimate friends, and hiding his prosperity until the day should come when he could announce his good fortune to the world at large. One of the last portraits of Balzac at this period is the one traced by Champfleury, whom he had received as a disciple and fervent admirer:
