R. I. C. HEAD OF THE CHEMISTRY DEPARTMENT AND LECTURER AND ADVISER IN AGRICULTURAL CHEMISTRY, ESSEX INSTITUTE OF AGRICULTURE, WHITTLE AND J. ELPHIN WATKIN, B. Sc., Ph. D., A. R. I. C. LATE LECTURER IN AGRICULTURAL CHEMISTRY, ESSEX INSTITUTE OF AGRICULTURE, WHITTLE WITH A FOREWORD BY SIR JOHN RUSSELL, D. Sc., F. R. S. MACMILLAN AND CO., LIMITED ST. MARTINS STREET, LONDON 1947 FOREWORD BY SIR JOHN RUSSELL, D. Sc., F. R. S. Director of the Rothamsted Experimental Station. THE authors of this book need no introduction to agricultural experts and agricultural students. Their association with the Chemical Department of the Essex Institute of Agriculture, one of the oldest and best known Agricultural Institutes in this country, has brought them in contact with large numbers of agriculturists, and has given them a wide knowledge of the educational needs of agricultural students and the best ways in which these can be met. The authors have the further advantage of being themselves research workers in soils and plant growth, so that they are in a position to view the problems as a whole, right from the re search laboratory to the farm. In this book the treatment is throughout sufficiently elementary for the young student, yet it has been so designed that he will have nothing to unlearn if he elects to take up a scientific or advisory career. A further valuable feature is that explanations are given not merely of the processes performed, but of the relation of the experiment to the whole subject, so that thestudent may be able to appreciate the bearing of his laboratory exercises on farm practice. The book will be of great help to agricultural students, and will add to the already high reputation of the authors and of the Institute with which they are connected. E. J. RUSSELL. Rothamsted Experimental Station, HERTS, May 1936. PREFACE THIS book has been produced to meet the requirements of students preparing for the B. Sc. degrees in Agriculture, Horti culture and Dairying, for the National and College diplomas in these subjects, and in Poultry Husbandry. Much of the work in practical chemistry is common to all these examinations, but there are necessarily differences in the emphasis placed on the various branches. The student taking a degree or diploma in Agriculture is expected to have a general knowledge of the whole ground covered by the book and to pay greater attention to some sections more vitally affecting Agri culture, e. g. feeding stuffs. The Poultry student, however, will probably omit the sections on soils, dairying and insecticides. The Dairy student likewisewill omit the sections on soils and insecticides. The experience of the writers with their own students has convinced them that the latter require a book which contains, in suitable form, a considerable amount of material at present only accessible in scientific journals, specialised books and miscellaneous publications, and which has discarded obsolete methods and views. In the absence of a suitable book, it has been our practice for many years to issue typed sheets of instructions for labora tory work which have periodically received re vision and addition. These sheets form the nucleus of the present book, in which thelarger amount of annotation possible should have the two fold effect of making laboratory work more nearly appear in its rightful perspective, and of reducing the time occupied by mechanical note-taking in lecture periods.
