viii Preface 



under obligations to Dr. Jas. A. Nelson and George S. Demuth 

 for friendly advice and assistance. To F. V. Coville, of the 

 Bureau of Plant Industry, thanks are due for assistance on 

 the chapter on the sources of honey and to Dr. C. C. Miller for 

 counsel on spring management and comb honey, on which sub- 

 jects he is the highest authority. Especially to his wife, the 

 author would express his gratitude for most valuable help. 



The illustrations with a few exceptions were either drawn 

 for this book from material gathered from many sources or 

 have been borrowed from publications prepared in the oflS.ce 

 of bee culture investigations of the Bureau of Entomology. 

 The new drawings are by J. E. Strauss. A few illustrations 

 copied directly from other sources are credited individually. 



In presenting a book to American beekeepers, the author 

 would express the hope that it may be as helpful to them as 

 the cordial assistance and cooperation of many of them have 

 been to him in his work.
