A whole series of new problems have arisen within a single generation and have called forth more or less successful attempts at their solution. Among these new problems we may properly include that of the bacteria, those minute living things that float in the air that we breathe, that exist for our weal or woe in the water that we drink, that perform a mighty work in the soil and thereby make it possible for generations of plants and of animals to come and go.

The extreme smallness of the bacteria renders them invisible to the naked eye, and makes it difficult for the layman to think of them as definite living beings entrusted with an important task in the continuing of life. The deepening current of human existence now forces us to study the bacteria and x other microorgan- isms.

In so far as they are dangerous to our health and happiness we must learn to defend ourselves we must learn to destroy them or to render them harm- less. In so far as they are beneficial, we must learn to vii viii Preface control them and to make their activities widely useful to human society.

The present volume is an attempt to treat, in a simple way, of the bacteria as they in the country. It is an attempt concern life to discuss the char- acter of the bacteria in air, water, sewage, manure, soil, and food products. Technical terms and expressions have been eliminated as far as practicable, and it is hoped that the general reader may find the book an aid in the understanding of the bacteriological problems as they affect the daily tasks on the farm. The author wishes to expresshis indebtedness to Messrs. Percy E. Brown and Herbert Seidman for their assistance in the preparation of the index and to Dr.
