Another notion that dies hard is one assuming that, since the children's librarian is a woman, prone to turn white about the gills at the sight of blood--or a mouse--she can not possibly enter into the feelings of the ancestral barbarian surviving in the young human breast, but must try to hasten the child's development to twentieth century civilization by eliminating the elemental and savage from his story books. If those who grow hoarse shouting the above would take the trouble to examine the lists of an up-to-date library they might blush for their shallowness, that they have been basing their opinions on their memory of library lists at least twenty-five years old. We do not believe that womanly women and manly men are most successfully made by way of silly, shoddy, sorry-for-themselves girlhoods, or lying, swaggering, loafing boyhoods; and it is the empty, the vulgar, the cheap, smart, trust-to-luck story, rather than the gory one, that we dislike. I am coming to the statement of what I believe to be the problem most demanding our study today. It is, briefly, the problem of the mediocre book, its enormous and ever-increasing volume. More fully stated it is the problem of the negatively as the enemy of the positively good; of the cultivation of brain laziness by "thoughts-made-easy" reading. It is a republic's, a public school problem, viz.: How is it possible to raise to a higher average the lowest, without reducing to a dead level of mediocrity the citizens of superior possibilities? Our relation to publisher and parent, to the library's adult open shelves of current fiction enter into the problem. The children's over-reading, and their reluctance to "graduate" from juvenile books, these and many other perplexing questions grow out of the main one.
