There must be one person who is making the standard for conduct and that person must be on hand during hours when trouble is likely to arise; that means the librarian. Assistants must be in sympathy, watch, help and report cases, but not take active part in discipline. The penalty must be a very certain thing, as sure a law in the public library as violation of law on the streets. There must not be nagging of young people nor wasting of words. When a transgressor is told to do anything, it must be done in such a manner, and without anger or annoyance in voice, if possible, so that a librarian can turn away and know the order will be obeyed. I believe it is possible to establish a standard of conduct in a public library, which a young person will feel and know if he is not within that standard. It can not be done in a week nor a month. I hope we have one here now. I mean by that also that a librarian can leave the library and not feel that any advantage is going to be taken of an assistant because she is not there. I do not believe in a librarian popping in any time during her off hours making the young people feel she is ready to spring upon them at unexpected moments. The above states what we have been doing, and we seldom now have to think of discipline. If we see signs of carelessness, we nip them in the bud. One must discriminate between a moment's thoughtlessness in a young person and the beginning of a wrong library habit. That may not seem clearly put. A firm, steady glance in his direction and the way he takes it will usually diagnose the case. I think the object of discipline in a Public Library is much more than to keep young people quiet. It seems now-a-days one of the few public places where they may mingle with older people and show them consideration. A quiet library ought to be an antidote for unseasonable boisterousness suffered by young people. No librarian need fear she is driving people away, if she tightens up all along this line. That at least has not been our experience, as we grew rapidly while we were the most strenuous. People have more respect for an institution, where each person will be held to his privileges, and not be allowed to interfere with another's. I was amused the other night when a high school boy, who had needed suggestion himself two years ago, came to me and said he thought two younger boys were disturbing an older gentleman in the reference room. These younger boys who were only talking more than was necessary, had not used the reference room and did not clearly understand that the same amount of conversation was not allowed there as in the other room. I spoke to them and when I returned suggested to the older boy that he might keep an eye on them, as I much preferred they stay there and think of the older man than come into the other room. He reported that they gave no more trouble.
