vm PREFACE 



Wisconsin in 1940. Since that time, however, the manuscript has been 

 extensively revised and enlarged. As it now stands, Chapters I, II, and IV 

 are primarily the work of Hicks, and the rest of the book the work of 

 Saloutos. But we have consulted and advised together constantly, and 

 we hope that the result is a continuous and unified narrative. 



We are deeply indebted to the Committee on Research of the Univer- 

 sity of Wisconsin for its long-continued support of this project. Professor 

 John D. Black of Harvard University read the manuscript, and favored us 

 with many pertinent suggestions. Finally, we owe much to many libraries 

 and many librarians.
