Fundamental of economic geography
THE FIFTH edition of this book differs to a con siderable extent from the previous one. Only in Chapters 6, 13, 14, 17. and 30 have the changes been minor All other chapters needed to be brought up to date and considerable re writing and reorganization proved to be de- sirable The present Chapter 1 was considered to be a better introduction to the subject matter of the book Chapter 19 was written as an in- troduction to the study of the mineral resources, as Chapters 6 and 7 constitute an introduction to the agricultural resources Through a dis cussion of power utilization, Chapter 19 leads logically into the following discussions of water and water power, coal, petroleum and natural gas, and the nuclear energy minerals. The dis cussion of minerals and rocks of direct economic use has been moved from the beginning of the part of the book devoted to the mineral re sources to its end This appears to be a more logical sequence from an economic geographic point of view Most of the maps, diagrams, and graphs required remaking and redrafting A number of old ones have been omitted and new ones have been added Also, many of the photographs have been replaced.
