LETTER OF TRANSMHTAl. 



U. S. Department oi" Agriculture, 



Bureau of Entomology, 

 Washington, D. G., September £3, 1912. 

 Sir : I have the honor to transmit herewith a manuscript entitled 

 " The Behavior of the Honey Bee in Pollen Collecting," by Dr. Dana 

 B. Casteel, of this bureau. The value of the honey bee in cross pol- 

 linating the flowers of fruit trees makes it desirable that exact infor- 

 mation be available concerning the actions of the bee when gathering 

 and manipulating the pollen. The results recorded in this manu- 

 script are also of value as studies in the behavior of the bee and will 

 prove interesting and valuable to the bee keeper. The work here 

 recorded was done by Dr. Casteel during the summers of 1911 and 

 1912 at the apiary of this bureau. 



I recommend that this manuscript be published as Bulletin No. 121 

 of the Bureau of Entomology. 



Respectfully, L. O. Howard, 



Entomologist and Chief of Bureau. 

 Hon. James Wilson, 



Secretary of Agriculture.
