Excerpt from Announcement of the Program Committee: Fourth International Congress on School Hygiene; Second Tentative Schedule of Papers (Subject to Further Revision); Buffalo, New York, U. S. An;, August, 25-30, 1913 I. The program committee is particularly anxious that the papers presented at this Congress shall deal largely with results secured through the practical application of scientific facts and procedures of school hygiene, and with the results of scientific investigation and laboratory research. Teachers, investigators, physicians, dentists, sanitarians and public-spirited citizens who have evidence showing that the school hygiene under their observation has been effective and of real service, or who can present scientific facts proven by their labors, will be welcome contributors. II. The committee is further anxious to secure papers relating to Rural School Hygiene and Village School Hygiene as well as to City School Hygiene. The problems of the city schools have received a great deal of much deserved attention. The very serious problems of the village school and the rural school have received but little attention. The study and the solution of these problems are of obvious complexity and importance. III. The following rules have been established by the program committee: 1. The official languages of this Congress shall be English, French, German, Spanish and Italian. 2. Papers must be limited to fifteen minutes in presentation. 3. Manuscripts submitted for publication in the Proceedings must not exceed three thousand words. 4. Time will be assigned on each program for the open discussion of groups of related papers. 5. Individuals participating in the open discussion may be limited to three minutes each, and such discussion may be determined at the discretion of the presiding officer. This rule is laid down for the purpose of enabling the presiding officer to put his schedule through on time. Preliminary abstracts will not be published.
