"These exhibits represent in concrete form the artistic and industrial development of this country, and in viewing them one cannot but be impressed with the great improvement in the conditions affecting our material and physical welfare and with the corresponding advancement in our intellectual and esthetic life. "Let us consider for a moment the processes by which this result has been reached. We have here collected the products of our artistic, scientific and industrial life. The raw materials of the farm, the vineyard, the mine and the forest have been transformed by the skilled artisan, the artist and the architect into the finished products before you. By the co-operation of all these resources, of all these activities, of all these workers, this result has been accomplished. From the felling of the trees in the forest, the tilling of the soil and the mining of the ore, through all the steps and processes required to produce from the raw material the complicated machine or the costly fabric, there must have been co-operation, and all incongruous elements and resistant forces must have been eliminated or overcome. "The chief factor, therefore, which has contributed to these results is the co-operation of all our people. The first law of our civilization is the co-operation of all individuals to improve the conditions of life. By division of labor each individual is assigned to or takes his special part in our social organization. This specialization of labor has become most minute. Not only is this true in scientific and philosophic research, in professional and business life, but in the simplest and earliest occupations of men, such as the tilling of the soil, the specialist is found bringing to the aid of his industry expert and scientific knowledge. "... In the division of labor and the resultant specialization of human activity we have necessarily different classes of workers, some of whom have adopted the co-operative idea by forming organizations by which they seek to better their conditions. No doubt each class of workers has its particular interests which may be legitimately improved by co-operation among its members, and thus far the labor organization has a lawful purpose, but while standing for its rights it cannot legitimately deny to any other class its rights, nor should it go to the extent of infringing the personal and inalienable rights of its members as individuals. On the contrary, it must accord to its own members and to others the same measure of justice that it demands for itself as an organization.
