With many libraries a children's department on such a scale is an impossibility; but if you cannot give two rooms to the children give them one, and if you cannot do that, at least give them a corner and a table which they can feel belongs to them; and if you cannot give them a special assistant, set apart an hour or two each day when the children shall receive the first consideration--establish this as a custom, and both adults and children will be better served. Whatever one's specialty in library work may be, however far removed from the work with the children, it is well to understand something of the principles which underlie this foundation work with the children. It is only recently that these principles have begun to shape themselves with any definiteness; the children's department, as a fully equipped miniature library, and the children's librarian, as a specialist bringing natural fitness and special preparation to her work, are essentially the product of today; but they have come to stay, and they open to the child-lover, and the educator who works better outside than inside of the schoolroom limits, a field enticing indeed, and promising rich results. It is to the pioneers in this field, the earnest young women who are now doing careful experimental work and giving serious study to the problems that arise--it is to them that the children's departments of the future will be most indebted for perfected methods. The library must supplement the influence of the schools, of the home, and of the church; with some children it must even take the place of these other influences, and on its own account it must be a source of pleasure and an intellectual stimulus. If it is to accomplish all or any great part of this, not only for one, but for thousands of children, what serious thought and labor must go to its accomplishment! The children's librarian stands very close to the mother and the teacher in the power she can wield over the lives of the little ones. No one who lacks either the ability or desire to put herself into sympathetic touch with child-life should ever be assigned to work in the juvenile department, and the assistant who avowedly dislikes children, or who "has no patience with them," will work disastrous results if allowed to serve these little ones with an unwilling spirit --she should be relegated to some department of the library to which the sunshine of childhood can never penetrate, and kept there. I would name the following requisites for the successful accomplishment of the juvenile work: (1) Love for children. This being given, the way is open for intimate knowledge and understanding of them, which are likewise essential. (2) Knowledge of children's books.
