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 office 
of bee culture investigations of the Bureau of Entomology. 
The new drawings are by J. F. 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.
