Sewerage and Sewage Treatment

Abstract

secondary school. Undoubtedly, many teachers of the last generation would have considered this material at the college level. Now similar texts intended for college students will have to approach the professional level. Personal hygiene with tidbits of anatomy and physiology still dominates the course in health for most high school students. But this book leads the reader into the realm of preventive medicine and public health-a worthy venture. Possibly more emphasis could have been given the subject of industrial hygiene, and mention made of the emergency medical procedures for Civil Defense; however, these topics can easily be added by the teachers themselves. The book is set in an easy-to-read two-column style and profusely illustrated with impressive photographs and clever cartoons. Using questions as captions is a painless way of inciting even more interest in the pictures. Had some of the references in the Teacher's Manual been printed in the text, the students would find the book more valuable for future reference; nevertheless, they will still consider it a prize possession.
