I wish again to express my thanks and gratitude to our 
wide-awake American apiarists, without whose aid it would 
have been impossible to have written this work. I am 
under special obligation to Messrs. Cowan, Newman and 
Root, and to my many students who have aided me, both 
in the apiary and laboratory. 
As I stated in the preface to the eighth edition, it is my 
desire and determination that this work shall continue to 
be the exponent of the most improved apiculture; and no 
pains will be spared, that each succeeding edition may 
embody the latest improvements and discoveries wrought 
out by the practical man and the scientist, as gleaned from 
the excellent home and foreign apiarian and scientific 
periodicals.
