xii INTRODUCTION TO THE AMERICAN REVISED EDITION 



is preferable (with the index in a separate volume). For classroom 

 use Goode's Homolosine Map of the World, with smaller maps of 

 world rainfall and of vegetation districts on the same sheet, is to be 

 commended (Rand McNally). 



The basic translation for the present edition was made largely by 

 the junior editor who also revised the translations of others collaborat- 

 ing with him. Dr. A. M. Holmquist translated Chapters XV, XXI, 

 and XXII, and checked the translation of Chapter XX, prepared by 

 M. M. Berger. Miss Pauline Hahn translated Chapters XVI to XIX, 

 inclusive. Various colleagues in our fields of interest have been helpful 

 with criticism and advice. Miss Charlotte D. Stephany has aided with 

 the manuscript and with the form of the bibliographic references. We 

 are greatly indebted to Miss Janet Wilder for an intelligent, search- 

 ing, and patient check of the whole manuscript and bibliography.
