334 SCIENCE PROGRESS 



The arrangement of material in this book is certainly unusual, and it is 

 dif&cult to understand what particular advantage is supposed to accrue from 

 its adoption. The chief value of the book undoubtedly lies in the part dealing 

 with poisonous plants, for here information is collected in one place which is 

 probably not to be found within the covers of any other single volume of 

 such small compass, and for this reason it should be found useful to agri- 

 cultural students in this country. W. S. 



How to Teach Agriculture : A Book of Methods in this Subject. By Ashley 

 V. Storm, Ph.D., Professor and Chief of the Division of Agricultural 

 Education and Director of Short Courses, University of Minnesota, 

 and Kary C. Davis, Ph.D., Knapp School of Country Life, George 

 Peabody College for Teachers. [Pp. vii + 434.] (London: J. B. 

 Lippincott Company, 1921. Price 12s. 6d. net.) 



This book is mainly intended for the teacher of agricultural students, but it 

 will probably be of help and interest to the intelligent student as well. 

 Sixteen of its eighteen chapters are designed to inform the reader how to 

 organise and manage teaching in agriculture, and how to teach the various 

 branches of the subject. The range of information given is very wide, among 

 the hundreds of questions dealt with being " The Socratic method," " Skill," 

 " Class Work in Animal Husbandry," " Soil Laboratory Work," " Responsi- 

 bility to Local Press," and so on. Although the outlook of the book is 

 possibly not identical with that of most teachers of agriculture in its various 

 branches in this country, it undoubtedly contains a wealth of information 

 based on the experience of those who are well acquainted with the matters 

 on which they write. The work is well printed on good paper and is well 

 written and illustrated. W. S. 



The Bases of Agricultural Practice and Economies in the United Provinces, 

 India. By H. IVUrtin Leake, M.A., Sc.D., F.L.S. [Pp. viii+277.3 

 (Cambridge: W. Heffer & Sons, 1921. Price 15s. net.) 



True advance in agriculture implies progress both in general farming methods 

 and in the recognition and application of economic factors, and while the 

 details vary from place to place, the general underlying principles remain the 

 same. In the present volume, the author has recognised this fact, and, while 

 his exposition deals with the development of agricultural practice and 

 economics in India, his deductions are of much wider bearing. 



Hitherto progress in India has been slow, as the climate presents many 

 problems, and the needs of the people are distinctly specialised and vary 

 considerably with locality. A forward movement is now taking place, and 

 the advance promises to move steadily along various lines in accordance witlx 

 the particular needs of the various districts. 



On the agricultural side, special attention is given to the relations between 

 the factors governing the growth of crops, distinction being drawn between 

 those which can be brought under control, and those which cannot. Hybridi- 

 sation, selection, manuring, and methods of cultivation are discussed from 

 the point of view of the Indian agriculturist. On the economic side it appears 

 that the most promising line of development is in co-operation of various 

 kinds, as independent action without co-operation threatens to stultify 

 advance. 



The book is exceedingly suggestive, and should be read not only for its. 

 bearing on Indian agriculture, but for its breadth of vision and the wider view 

 of the science of agriculture that it opens out.
