So much Mr. Owen left behind. Let us now follow him in his after career. He bade farewell to New Harmony and returned to England in June 1828. Acknowledging no real defeat or loss of confidence in his principles, he went right on in the labors of his mission, as Apostle of Communism for the world, holding himself ready for the most distant service at a moment's warning. His policy was slightly changed, looking more toward moving the nations, and less toward local experiments. In April 1828, he was again in this country, settling his affairs at New Harmony, and preaching his gospel among the people. During this visit the challenge to debate passed between him and Rev. Alexander Campbell, and an arrangement was made for a theological duel. He returned to England in the summer, and in November of the same year (1828) sailed again for America on a scheme of obtaining from the Mexican government a vast territory in Texas on which to develop Communism. After finishing the negotiations in Mexico (which negotiations were never executed), he came to the United States, and in April 1829 met Alexander Campbell at Cincinnati in a debate which was then famous, though now forgotten. From Cincinnati he proceeded to Washington, where he established intimate relations with Martin Van Buren, then Secretary of State, and had an important interview with Andrew Jackson, the President, laboring with these dignitaries on behalf of national friendship and his new social system. In the summer of 1829 he returned to England, and for some years after was engaged in labors for the conversion of the English government, and in some local attempts to establish "Equitable Commerce," "Labor Exchange" and partial Communism, all of which failed. Here Mr. Sargant, his English biographer, gives up the pursuit of him, and slurs over the rest of his life as though it were passed in obscurity and dotage. Not so Macdonald. We learn from him that after Mr. Owen had exceeded the allotment of three-score years and ten, he twice crossed the ocean to this country. Let us follow the faithful record of the disciple. We condense from Macdonald:
