Perhaps the most attractive room to the younger children is the History room, in which the beginnings of American history are typified not only by charts and historic implements, but by very real "doll houses." A member of the staff devised and cleverly executed the idea of representing the early settlers by six colonial types, viz., the Spanish, French, Cavalier, Dutch, New England and Quaker types. Some of the special scenes illustrated are labelled "Priest and soldier plan a new mission," "Indians selling furs to Dutch trader at Fort Orange" and "The minister calls on the family." The study of geography is aided by means of small models of miniature homes of primitive peoples; as for instance, an Eskimo village with its snow igloos, the tents of the Labrador Eskimos, the permanent home of the Northwestern Eskimos, and the houses and "totem poles" of the Haida Indians. Some of the more civilized nations are typified by a "Lumber camp in a temperate zone," and by a series of "Dolls dressed in national costumes." The library of the Children's Museum now numbers about six thousand volumes, and, contrary to the general impression, is not composed entirely of children's books, but of a careful selection of the best recent books upon natural history in the broadest use of the terms. The range is from the simplest readers to technical manuals. The library is thus unique in its way, supplementing the work of the museum in various ways, such as the following: 1. Providing books of information for the museum staff in describing the collections, and preparing lectures for children. 2. Furnishing information to visitors about specimens models or pictures in the museum, and giving opportunity to study the collections with the direct aid of books. 3. Offering carefully chosen books on almost all the subjects of school work, thus forming a valuable "School reference library," at the same time showing parents and teachers the most helpful and attractive nature books to aid them in selecting such as best suit the needs and tastes of children or students. Although it is not a circulating library (for many of the books need to be on call for immediate use), there are, of course, many interesting stories of heroes, scientists, explorers, statesmen, and other great leaders among men, of great events in history, of child life in different countries, of birds and animals, and the great "world of outdoors." A constant effort is made to foster a reading habit in the children, even though the time for reading is very limited. Last summer some simple bookmarks were printed, by the use of which many children have been encouraged to read books continuously. The reverse side of some of the bookmarks show that individual children have read eight or ten books through recently.
