Unfortunately, the future always does take care of itself very well indeed, and presents itself to demand a reckoning at the appointed time. The library, for instance, that has its branches for different regions and its children’s room in each gets along well enough so long as its cross-classification of work exists only on paper. But the time comes when departmental organization must begin, and this must be based on the classification. There may be a superintendent of branches and a superintendent of children’s work, or the branch librarians may report to the librarian directly, or there may be other dispositions with other duties and names. In any case, a children’s room at a branch library necessarily finds itself in two departments, under two jurisdictions and under two heads. If the branch librarian and the children’s superintendent are both yielding in disposition, the librarian may never have the conflict of jurisdiction brought to his attention. If either is yielding while the other is masterful, there will also be no trouble. In one case the branch librarian will run the adult end of her branch and leave the other to the children’s department; in the other there will be one branch, at least, where the children’s supervisor has little to say--a condition of things that may be tolerated, but is surely undesirable. But suppose that both heads are conscientious, assertive and anxious to push the work, fond of organizing administrative details and impatient of interference. Here we have the possibilities of trouble at once. The first rumblings of the storm come usually in the form of complaints of interference, on the one side or the other. Then we have a demand from both sides for a definition of their respective rights and responsibilities. The librarian is asked, for instance, in just what respects the children’s librarian shall take her orders from the branch librarian and in what from the supervisor. This is a good deal like petitioning the legislature to pass a law specifying exactly when a child shall obey his father and when the mayor of the city. The librarian who enters on this plausible path will sooner or later be lost in the jungle. He has only himself to thank. Either he or his predecessor started the game and he must play it out to the end. We librarians are all responsible for each other’s faults. Let us see how he may play it. In the first place, his is the power. What is done in any department is done by his orders or by the orders of some one endowed by him with authority to give orders. He has given two persons authority over the same field at one point, and it is his business to straighten things out. Here are some possible ways:
