The difference between them is that while the trades-union is confined to the trade, the Socialist party embraces the entire working class, and while the union is limited to bettering conditions under the wage system, the party is organized to conquer the political power of the nation, wipe out the wage system and make the workers themselves the masters of the earth. In this program, the trades-union and the Socialist party, the economic and political wings of the labor movement, should not only not be in conflict, but act together in perfect harmony in every struggle whether it be on the one field or the other, in the strike or at the ballot box. The main thing is that in every such struggle the workers shall be united, shall in fact be unionists and no more be guilty of scabbing on their party than on their union, no more think of voting a capitalist ticket on election day and turning the working class over to capitalist robbery and misrule than they would think of voting in the union to turn it over to the capitalists and have it run in the interest of the capitalist class. To do its part in the class struggle the trades-union need no more go into politics than the Socialist party need go into the trades. Each has its place and its functions. The union deals with trade problems and the party deals with politics. The union is educating the workers in the management of industrial activities and fitting them for co-operative control and democratic regulation of their trades,—the party is recruiting and training and drilling the political army that is to conquer the capitalist forces on the political battlefield; and having control of the machinery of government, use it to transfer the industries from the capitalists to the workers, from the parasites to the people. In his excellent paper on “The Social Opportunity,” published in a recent issue of the International Socialist Review, Dr. George D. Herron, discussing trades-unions and their relation to the Socialist party, and the labor movement in general, clearly sees the trend of the development and arrives at conclusions that are sound and commend themselves to the thoughtful consideration of all trades-unionists and Socialists. Says Dr. Herron:
