"So long as the uses of the imagination in creative work are so little comprehended by the great majority of men, it can hardly be expected that its practical uses will be understood. There is a general if somewhat vague recognition of the force and beauty of its achievements as illustrated in the work of Dante, Raphael, Rembrandt and Wagner; but very few people perceive the play of this supreme architectural and structural faculty in the great works of engineering, or in the sublime guesses at truth which science sometimes makes when she comes to the end of the solid road of fact along which she has traveled. The scientist the engineer, the constructive man in every department of work uses the imagination quite as much as the artist; for the imagination is not a decorator and embellisher, as so many appear to think; it is a creator and constructor. Wherever work is done on great lines or life is lived in field of constant fertility, the imagination is always the central and shaping power." I would have liked in this over-lengthy, but yet fragmentary survey of the field from the viewpoint of the library, to say something of the mistakes which have perhaps been made, and which may still be made unguardedly by reason of over-zeal whereby the relationship of the work to other things may be ignored or misunderstood; of the danger that over-strong consciousness as to possession of high ideals may dictate too urgent use of books that may have literary style, but do not reach the heart of the boy--driving him to the comic supplement and to the dregs of print for his reading hours. These, and other comments must be left for another occasion. I would also have liked to say something of the history of work with children in libraries, but Miss Josephine Rathbone has told the story fully and well. In that history, when it shall be written a quarter century hence, it will be fitting to give full meed of honor to Samuel Sweet Greene, Edwin H. Anderson, Mrs. H. L. Elmendorf, Miss Frances J. Olcott, Miss Linda A. Eastman and some of the other splendid women of the profession whose presence here precludes the mention of their names. So, too, I would have liked to give the result, statistically, of an inquiry, which the helpful kindness of Miss Faith E. Smith, chairman of this section, has enabled me to make. It must suffice here to limit the statement to a brief summary that shows less what has been accomplished than what remains to be attempted:
