really worth their reading. If good books would not be read, then the plan should be given up. Had we been careless in the selection of books we easily might have done no little harm, and should not have learned that clean, unsensational, vigorous books that are loved by children in the homes of the well-to-do are welcome to children in the homes of the poor. The way to good taste in reading is not, as some curiously declare, through the mire of the dime novel and the sensational story, but straight along the clean, bright path of decent literature. Although, by reason of the natural preference of some visitors, or the effect of changes in groups at first made up of both sexes, some groups are wholly made up of boys and others of girls, the ideal group is a mixed one as regards both sex and age--ten boys and girls from seven or eight to fifteen or sixteen years of age. Thus we provide for a healthful, unconscious association of the sexes and the training of the younger and older in their behavior toward one another, and in general touch the maximum range of relations, difficulties and services. It follows from this make-up of a group that our books must be varied in order that in each set there shall be food for each child. So every library is made up of fifteen volumes, running the whole gamut from the nursery tale to Tom Brown at Rugby or Uncle Tom's Cabin, and also selections from juvenile periodicals suited to children of different ages, there being five collections of periodicals in each library, each collection comprising a bound portion of the annual issue of some periodical. You will readily see, therefore, that in order to select a new library it is necessary to have forty or fifty approved and unassigned books to choose from, and never is a set made up with its fairy tales, pictures of sweet domestic life, stories of adventure, simple history and biography, short stories, long stories, fact and fancy, humor and pathos--never is a set made up, preliminary to starting out upon its first visit, without my mouth watering to read them all myself. To put the books to an interesting test, but more especially to induce the children to read appreciatively and really use their minds as they read, a form was made out on which the librarian or visitor should record the opinion of each child in regard to each book he returns. The evolution of these opinions from the obnoxiously frequent "nice" and "very nice," or the occasionally refreshing "no good," of the early history of a group into really intelligent and discriminating opinions, is one of the sure marks of progress and value in the work. A set of books usually remains with one group of children ten weeks or three months before it is exchanged for a fresh set and in turn goes to another group. So you see the Home Libraries stand for nothing less than a perennial and constantly fresh stream of good literature.
