In speaking of a co-operative union we generally mean a group of associations which, for the purpose of facilitating their work, establish mutual relations for collaborating with one another along certain lines, appointing a common directorate with varying powers and thenceforth carrying out a common line of action. The average citizen is pleased and reassured when he hears that these associations, by establishing a co-operative union among one another, have at long last discovered a common platform on which they can stand united and have eliminated all grounds of mutual difference. Therewith a general conviction arises, to the effect that such a union is an immense gain in strength and that small groups which were weak as long as they stood alone have now suddenly become strong. Yet this conviction is for the most part a mistaken one.
