PREFACE


Nearly six tenths of the earth's land surface receive an annual
rainfall of less than twenty inches, and can be reclaimed for

one half of the earth's land surface to be reclaimed, if at all, by
the methods of dry-farming. The noble system of modern agriculture
has been constructed almost wholly in countries of abundant
rainfall, and its applications are those demanded for the
agricultural development of humid regions. Until recently irrigation
