Since the publication by the Bureau of Education of Bulletin (1910) No. 5, entitled "American Schoolhouses" much progress has been made in school architecture from every point of view. In this revised edition such changes and such additions have been made in the text as will, it is hoped, bring this progress to the attention of school authorities in all essential details. The illustrations, both of floor plans and elevations of school buildings, are mostly new, and serve as an attempt to give a cross section of present acceptable standards. The preparation of this edition was undertaken with the hope that some additional helpful material might be brought to this service. The Commission of Education has requested some of the most prominent school architects of the country to furnish for this volume floor plans and elevations of a number of their most successful buildings. This volume will, in the main, show only high-school buildings, both senior and junior, and large buildings for grammar schools for city conditions. Those for the country schools will appear in another bulletin. The following topics are covered in this bulletin: (1) Location of a schoolhouse; (2) Soil and drainage; (3) Protection against dampness; (4) Planning; (5) Construction and equipment; (6) Lighting; (7) Heating; (8) Ventilation; (9) Toilets; (10) Disposal of sewage; (11) Baths; (12) Swimming pool; (13) Gymnasiums; (14) Playgrounds; (15) Laboratories; (16) Assembly rooms; and (17) School architecture and school improvement. An appendix presents: Orientation of buildings in Southern States. An index is also included. (Contains 7 figures, 45 plates, and 4 footnotes.) [Best copy available has been provided.]
