The latter body was the outgrowth of a convention held in Pittsburg in 1881, but it did not adopt its final name until 1886. Its purpose was to group labor organizations of all kinds, leaving the government of each affiliated body with the body itself. Each of the members of the Federation is composed of workers in a given trade or industry, like the International Typographical Union, the United Mine Workers, and many others. The annual convention is composed of delegates from the constituent societies. The growth of the organization was rapid and continuous. Coincidently with the expansion of the Knights of Labor and the growth of the American Federation came the great development of the labor press. Professor Ely estimated late in the eighties that possibly five hundred newspapers were devoted to the needs of the labor movement. The numerous farmers' organizations, typified by the Patrons of Husbandry, are other examples of the growing tendency toward cohesion among the less powerful classes. Indeed, the Grange originated only a year earlier than the Knights of Labor, and like it was a secret order. The wage earners, then, were rapidly becoming class-conscious. They had found conditions which seemed to them intolerable, had formed organizations on a national scale and had drawn up a definite program of principles and reforms. The exact grievances which inspired the Knights, the Federation and other less important organizations are therefore of immediate importance. In order to secure for the wage earner a sufficient money return for his work, and sufficient leisure for the education of his intellectual and religious faculties, and to enable him to understand and perform his duties as a citizen, the Knights demanded the establishment of bureaus of labor for the collection of information; the reservation of the public lands for actual settlers; the abrogation of laws that did not bear equally on capital and labor; the adoption of measures for the health and safety of the working classes; indemnity for injuries due to the lack of proper safeguards; the recognition of the incorporation of labor unions; laws compelling corporations to pay laborers weekly; arbitration in labor disputes; and the prohibition of child labor. The Knights of Labor also favored state ownership of telegraphs and railroads, as well as an eight hour working day. The purposes of the American Federation scarcely differed from this program, although its methods and its form of organization were quite distinct.
