Hodgson YONKERS-ON-HUDSON, NEW YORK "Our national health is physically our Copyright, 1910, 1915, 1920, by World Book Company Copyright in Great Britain All rights reserved FOR the most effective health work in our schools, there must be thorough classroom instruction in hygiene; the teachers must exert every effort to see that the knowledge acquired in the classroom finds expression in the lives of the pupils; and the school authorities must provide medical supervisors competent to prevent the spread of infections and to correct remediable physical defects. On the importance of laying a sound educational foundation for our health work, there is little disagreement at the present time. Those who know human history in its wider phases understand the certainty with which ideas unloosed express themselves in time in the lives of men. The culmination in recent days of systematic campaigns of education and propaganda in our own country and elsewhere in the world has demonstrated anew that the beliefs of men profoundly influence their actions, and that the future belongs to those who can secure the acceptance as truth of the ideas they advocate. The authors, therefore, venture to express the hope that in our schools we shall not only insist on the present application of hygiene to the pupils' lives, but shall also give to every pupil that sound instruction in hygiene which, in the end, conditions all our health work. In this text they have tried to encourage the formation of habits of right living, and to assist medical supervisors by showing the importance of their work. But their chief concern has been to provide a body of authoritative information in such form that it may be used for the instruction of the pupils in the more important facts and principles of hygiene. 570617 THE teacher who uses this text will find Rosenau's Preventive Medicine and Hygiene (Appleton, New York) and Jordan's Principles of Bacteriology (W. B. Saunders Company, Philadelphia) excellent advanced books to consult for information pertaining to bacteriology or public health.

Saunders Company, and in McCollum's The Newer Knowledge of Nutrition, published by The Macmillan Company, New York.
