BEE CULTURE INVESTIGATIONS 
Jas. I. Hambleton, in Charge 
Jas. I. Hambleton and W. J. Nolan attended the recent meetings of 
the American Association for the Advancement of Science held in New York 
City. At the session of the Apicultural Section of the American Associ- 
ation of Economic Entomologists Mr. Hambleton presented a paper showing 
that American honey exporters would greatly benefit by increased confi- 
dence in their product abroad if the United States Standards for honey 
were generally adopted in this country. He also read a paper prepared 
by Dr. C. E. Burnside, dealing with the latter's experiments on the use 
of formaldehyde gas for the disinfection of combs infected with American 
foulbrood. Doctor Burnside maintains that the method offers good possi- 
bilities when proper precautions are used, and that the labor and cost 
of treating combs in this way should be less than they are with water— 
formalin and alcohol-formalin solutions. He holds, nevertheless, that 
chances of failure are considerably greater with formaldehyde gas than 
when either of these solutions is used. This difference holds especi- 
ally in case of sealed cells of honey or brood, owing to the resistance 
offered by the cappings to penetration of the gas. Mr. Nolan gave a 
paper telling of the success obtained during the last two years at the 
Bee Culture Laboratory in using Watson's method for artificially insem—- 
inating queenbees. 
Prof. L. M. Bertholf, of Western Maryland College, presented a 
paper before the Zoological Society at its recent meeting in New York, 
dealing with his results obtained at the Bee Culture Laboratory on chroma 
vision in the honeybee. 
Recent visitors at the Bee Culture Laboratory included Chas. A. 
Reese, State Apiarist, Columbus, Ohio, Prof. L. M. Bertholf, of Western 
Maryland College, Westminster, Md., and W. E. Dunham, Instructor in 
Apiculture, Ohio State University, Columbus, Ohio.
