Présentation de l'éditeur

Bacteriology lias contributed, within the past few years, eome important facts to our rapidly expanding knowledge of soils. It has shed a new light on the transformation and accumulation of nitrogen compounds in tilled land, as well as in uncultivated forest and prairie soils. It has taught us to understand more clearly the decomposition of cellulose and allied compounds, and the conservation of the potential energy of hydrogen and of methane. It has given the student of soils and of soil fertility a number of new methods for measuring differences in the quality and quantity of plantfood. ,I tbids fair to supply us with still other methods that would be more adequate than any chemical methods yet devised, for the investigation of fundamental problems of soil fertility. In view of the past achievements of soil bacteriology and of the promise of even greater usefulness in the future, no apology is needed for the publication of this little volume. The authors have felt, for some time, that there is room in every well-arranged course in soils for a series of exercises in soil bacteriology, and have, therefore, made the attempt to provide them. It is their hope that after preliminary instruction in general bacteriology and laboratory technique the Guide will prove useful to students of soils, and that time and service will permit the elimination of the imperfections and inadequacies that undoubtedly exist in it. Toward this end, friendly criticism will be appreciated. Meanwhile, the authors wish to express their indebtedness roD r. E. E. Buchanan, of the Iowa State College, for many helpful suggestions.
