AGRICULTURAL BOOK REVIEWS 



MACK LIN, THEODORE. Efficient marketing 

 for agriculture; its services, methods, and 

 agencies. (Social sci. text-books) il Mac- 

 millan $3 338.1 21-15705 



On the ground that marketing consists in 

 rendering essential services and that without 

 the middleman both the producers and the con- 

 sumers of farm produce are at a loss, the 

 author undertakes to show that in the interests 

 of all concerned these services should be 

 rendered by the most efficient methods and by 

 agencies which in functioning take a minimum 

 share of the consumer's dollar. The assemb- 

 ling, grading and standardizing, packing, pro- 

 cessing, transporting, storing, financing 

 and distributing of farm products are con- 

 sidered in turn, and the best marketing 

 methods, agencies and price-making systems 

 are discussed in detail. To each chapter is 

 added a condensed summary and a list of 

 selected reading. There are illustrations, tables 

 and maps and an index. — Book Review Di-

MORRIS, ROBERT TUTTLE. Nut growing. 

 il Macmillan $2.50 634.5 19-19397 



The object of the book is to give the essen- 

 tials of nut growing — certain simple new 

 methods of grafting and of propagation — that 

 may serve as a guide to the general farmer 

 and amateur garden lover and which even the 

 professional nut giower may want to look over 

 in order to check up some of the things he 

 has forgotten about. Part one is devoted to 

 general notes on the food supply. Parts two 

 and three are given over to propagation and 

 species and varieties. The varieties discussed 

 are hickories, walnuts, hazels, chestnuts, pines, 

 beech, oaks and almonds. The book is in- 

 dexed and illustrated. ^ — Book Review Digest 



RASOR, SAMUEL EUGENE. Mathematics for 

 students of agriculture. '21 Macmillan $3 



21-15960 



"This book presents a year's work in mathe- 

 matics for students taking agricultural courses 

 in secondary, vocational, and technical schools 

 and in colleges and universities. By omitting 

 the more elementary or the advanced topics, 

 as may seem desirable, or by properly select- 

 ing the exercises to be solved, the book will 

 serve quite naturally for a half-year's work. 



The modern agriculturalist must devote a 

 larger and larger part of his time to mental 

 activity along scientific lines. To do this ra- 

 tionally he must have better methods for, and 

 more practice in, estimating, computing, and 

 comparing the materials and processes with 

 which he works. The object of the present 

 text is to furnish a better basis for effecting 

 these ends."— Preface

RECKNAGEL, ARTHUR BERNHARD, and 



BENTLEY, JOHN. Forest management. '19 



Wiley $2.50 19-12266 



This book purports to provide the American 



reader with a condensed and not too technical 



account of the subjects comprised under the 



bead of Forest management. 



The subject matter is treated under the fol- 

 lowing main heads: Forest mensuration; Forest 

 organisation (including working plans); Forest 

 finance; Forest administration. 



One hundred and twenty-two pages, or rather 

 more than half the book, deal with the subject 

 of Forest mensuration. Forest organisation 

 occupies fifty-five pages, the remaining sections 

 being more briefly dealt with. 



Chapters X and XI give a short but useful ac- 

 count of methods of determining the increment 

 of single trees and woods. We are bound to 

 point out, however, that on page 116 the deter- 

 mination of the volume of permanent sample 

 plots by the arithmetical mean sample tree 

 method is open to criticism on the ground that 

 other and more accurate methods (e.g., those 

 of Hartig and Urich) have long been employed 

 by the research stations in Europe. 



British students will find chapter XV on For- 

 est finance most useful as an introduction to a 

 subject which is often found troublesome. In 

 particular, the U.S.A. government's detailed in- 

 structions for calculating fire damages (on pages 

 201 to 208) provide interesting illustrations of 

 the practical value of compound interest formu- 

 las in general forestry. The final chapter deals 

 briefly with the subject of administration. We 

 fancy that most British foresters will be sur- 

 prised by the statement on page 217 that "while 

 the average executive unit in Europe is 6,000 

 acres, the average unit in the United States 

 national forests is no less than 1,022,200 acres." 

 Any except the most extensive system of work- 

 ing must be out of the question with units of 

 this size. 



The book is well printed and provided with 

 an appendix containing the usual compound in- 

 terest tables and other data; there is also an 

 excellent index. — J Min Ag
