Acknowledged with Thanks 



TO THE MEN whose words and deeds are the very 

 warp and woof of this book my gratitude is as great as 

 my obligations are evident. Without them the foregoing 

 pages could never have been written. To them I can say 

 no more, but there are others whose names do not 

 appear in the Index of this book who have helped me. 

 Some paved my way to strangers with introductions, 

 others supplied me with facts and figures, still others 

 have read parts of the manuscript critically and given 

 me the benefit of their corrections and suggestions. To 

 all these, my sincere thanks:
