the viewpoint is English and the method of approach is more that of the pure scientist than of the specialist in soil management, the material should be very useful to the English cultivator. It is, however, not the type of material which the American farmer finds in the bulletins of his experiment station. The author does not seem to be familiar with the progress that has been made in the United States in the manufacture of legume inoculants. He mentions the early European attempts in the preparation of the so-called "Nitragin" and dismisses the discussion with the statement that the sale of this material was discontinued, although the attempt was not without historical interest. Another omission of interesting work that is being done in this country has to do with the influence of gypsum on the structural condition of certain alkali soils. The author discusses the effect of gypsum in correcting black alkali, but states that it has no influence on white alkali soils. The discussion of artificial nitrogen fixation is also rather incomplete, the Haber process and certain other modern developments not being mentioned. The discussion is limited entirely to the manufacture of nitrate of lime and calcium cyanamide. On the whole, the book is not only exceedingly well written, but it contains a large amount of most valuable material. It is an excellent resume of our knowledge of the science of soils and fertilizers. The appendix includes much tabular material of value to the student. American students of soils and fertilizers will find this book a very worthy one for their libraries. (M. F. MILLER.)
