PREFACE.

As the title of this book suggests, the cereals have been treated principally with reference to their American environment, although valuable foreign data have often been included. This is especially true with reference to varieties, fertilization, culture, harvesting, production, use and marketing of these crops. It is not a monograph of experiment station literature. The limits of the work have made it impossible to include some valuable data. Moreover the author has deemed it his privilege to protect the reader by eliminating inconclusive and inconsequential data, which must of necessity accumulate in so large an enterprise as that represented by the various agencies for research in Agriculture. It is hoped, however, that the reader will find herein a fairly comprehensive, although concise, statement of experimental results as well as of farm methods relating to the cereals in America. Reference has usually been made to the station rather than to the individual for a number of reasons, the most important of which is that in the culture of these crops the location is frequently an important consideration. With few exceptions, the illustrations in this book have been drawn or re-drawn by C. W. Furlong or A. K. Dawson. The author wishes to express his grateful acknowledgment to those who have given him helpful suggestions, and especially to his secretary, Mr. C. C. Poindexter, B. S., O. S. U. 1903, for valuable assistance rendered.
