BEE CULTURE INVESTIGATIONS 
James I. Hambleton, in Charge 
Dr. Everett Oertel has been appointed an Assistant Apicultur- 
ist to fill a vacancy in the Southern States Bee Culture Field Labora- 
tory, recently established at Baton Rouge, La. He will devote his time 
largely tO the study of floral sources of nectar, manipulation of 
bees, and other factors closely related to the production of honey. 
Dr. Warren Whitcomb, Jr., of the Southern States Bee Culture 
Field Laboratory, Baton Rouge, La., attended the meeting of the Geor- 
gia State Beekeepers' Association at Macon, Ga., on Sept. 19, where 
he outlined the work of that laboratory. 
R. S. Kifer, of the Bureau of Agricultural Economics, visited 
the Bee Culture Laboratory on Oct. 2 to confer with members of the 
staff previous to his departure for the Intermountain States, where 
he will continue the studies on the cost of producing honey and meth~ 
ods of apiary management upon which E. L. Sechrist, of the Bee Cul-— 
ture Laboratory, has been engaged during the past summer. Mr. Kifer 
will make the final visit to all cooperators and close the work for 
the season. 
The American Honey Producers' League sponsored an exhibit of 
honey which was shown at the annual convention of the American Die— 
tetic Association, which met October 29 to 31 at the Willard Hotel. 
The success of the exhibit was in large part due to Dr. E. N. Cory, 
Secretary of the Maryland State Beekeepers' Association, who detailed 
members of the association to take care of the display. The colored 
poster advertising honey, published by the Bureau of Entomology, was 
conspicuously displayed, and the staff of the Bee Culture Laboratory 
assisted in the arrangements. 
In the July News Letter mention was made of the fact that at 
the time granulated honey was discovered in the apiary of the Bee Cul— 
ture laboratory the bees were found to be working largely on sweet 
clover. Since that time it has been determined that the granulation 
of the honey was due to the presence of melezitose, one of the rare 
sugars, and it is quite evident now that the bees had finished working 
the true source from which the melezitose was derived, which was probably 
the scrub pine, a tree occurring in abundance in this part of the 
country. For this reason it has been impossible to determine defin-— 
itely whether the melezitose was derived directly from an exudation 
of the scrub pines, or from honeydew collected from aphids. 
Recent visitors at the Bee Culture Laboratory included Dr. W. 
W. Alpatov, of the University of Moscow; Mr. Victor M. Buck, of the 
Presbyterian School, Ebolowa, Cameroun, West Africa; and Dr. J. A. 
Nelson, of Mt. Vernon, Ohio, who was formerly connected with the 
laboratory.
