Aside from systematized emigration to unsettled or thinly peopled regions, which the Trades-Unions of Europe ought to organize on a great scale, but which they have entirely neglected, the other outlets for the mass of dissatisfied hand-laborers lie through co-operative or communistic efforts. Co-operative societies flourish in England and Germany. We have had a number of them in this country also, but their success has not been marked; and I have found it impossible to get statistical returns even of their numbers. If the Trades-Unions had used a tenth of the money they have wasted in futile efforts to shorten hours of labor and excite their members to hatred, indolence, and waste, in making public the statistics and the possibilities of co-operation, they would have achieved some positive good. But while co-operative efforts have generally failed in the United States, we have here a number of successful Communistic Societies, pursuing agriculture and different branches of manufacturing, and I have thought it useful to examine these, to see if their experience offers any useful hints toward the solution of the labor question. Hitherto very little, indeed almost nothing definite and precise, has been made known concerning these societies; and Communism remains loudly but very vaguely spoken of, by friends as well as enemies, and is commonly a word either of terror or of contempt in the public prints. In the following pages will be found, accordingly, an account of the COMMUNISTIC SOCIETIES now existing in the United States, made from personal visit and careful examination; and including for each its social customs and expedients; its practical and business methods; its system of government; the industries it pursues; its religious creed and practices; as well as its present numbers and condition, and its history. It appears to me an important fact that these societies, composed for the most part of men originally farmers or mechanics--people of very limited means and education--have yet succeeded in accumulating considerable wealth, and at any rate a satisfactory provision for their own old age and disability, and for the education of their children or successors. In every case they have developed among their membership very remarkable business ability, considering their original station in life; they have found among themselves leaders wise enough to rule, and skill sufficient to enable them to establish and carry on, not merely agricultural operations, but also manufactures, and to conduct successfully complicated business affairs.
