Already the father of two children, and about to be presented with a third, Proudhon was obliged to devise some immediate means of gaining a living; he resumed his labors, and published, at first anonymously, the "Manual of a Speculator in the Stock-Exchange." Later, in 1857, after having completed the work, he did not hesitate to sign it, acknowledging in the preface his indebtedness to his collaborator, G. Duchene. Meantime, he vainly sought permission to establish a journal, or review. This permission was steadily refused him. The imperial government always suspected him after the publication of the "Social Revolution Demonstrated by the Coup d'Etat." Towards the end of 1853, Proudhon issued in Belgium a pamphlet entitled "The Philosophy of Progress." Entirely inoffensive as it was, this pamphlet, which he endeavored to send into France, was seized on the frontier. Proudhon's complaints were of no avail. The empire gave grants after grants to large companies. A financial society, having asked for the grant of a railroad in the east of France, employed Proudhon to write several memoirs in support of this demand. The grant was given to another company. The author was offered an indemnity as compensation, to be paid (as was customary in such cases) by the company which received the grant. It is needless to say that Proudhon would accept nothing. Then, wishing to explain to the public, as well as to the government, the end which he had in view, he published the work entitled "Reforms to be Effected in the Management of Railroads." Towards the end of 1854, Proudhon had already begun his book on "Justice," when he had a violent attack of cholera, from which he recovered with great difficulty. Ever afterwards his health was delicate.
