The result of the division produced a marked change in Mr. Mitchel’s career. His lectures on land-tenure in Europe, displayed the bold outlines and distinctive characteristics of his principles. His hopes from the Irish landlords, of whatever shade of politics, had ever afterwards vanished. He believed them incapable of being influenced by commonsense or good feeling; and he turned to the people, with full confidence in their fidelity and strength. All further attempts to conciliate the upper classes, he regarded as foolish, feeble and cowardly. He continued to reassert the substance of his lectures in another form, in the pages of the Nation, of which he was at the time editor-in-chief—that is, of which he wrote the greatest portion, especially of its leading articles. Some of these articles gave rise to a difference of opinion between him and Mr. Duffy, who, as responsible owner and editor, had the sole control of the Nation. There were not wanting men to take advantage of the difference and fan the flame. Charles Duffy had messages conveyed to him, to the effect that a rumour was abroad charging him with treachery; and to John Mitchel, perhaps by the same agents of dissension, it was stated that he, too, was suspected. It is unfortunately characteristic of Irishmen to be suspicious; and it was the object of one of Mr. O’Connell’s eternal lessons to perpetuate and extend this degrading national vice. Whether the representations made to either of these friends were the result of national prejudice, or proceeded from a baser motive, it is scarce worth while to inquire. A separation ensued. Mr. Reilly adopted the resolution of his friend Mr. Mitchel. Mr. M’Gee adhered to Mr. Duffy; and a new career and distinct fortunes opened to the enterprise of the four men, whose united efforts elevated the popularity of the Nation to a height never before enjoyed by an Irish journal.
