BEE CULTURE INVESTIGATIONS 
James I. Hambleton, In Charge 
L. M. Bertholf, Professor of Biology, Western Maryland College, has 
returned to the laboratory to continue his work on reactions to light in 
the honeybee. He is devoting his attention this summer mainly to the re— 
sponse of bees to ultra-violet light and its physiological effect on them. 
Mary L. White, who has been employed at the laboratory for several 
summers, has been reappointed temporary Field Assistant, to assist in the 
work on bee diseases. Willis R. Doyle also has been appointed temporary 
Field Assistant. 
The Southern States Bee Culture Field Station, at Baton Rouge, La., 
is very grateful to receive as a gift practically complete files of the 
American Bee Journal and Gleanings in Bee Culture, from Prof. H. B. Parks, 
Apiculturist at the Texas Agricultural Experiment Station, San Antonio. 
This addition is a very welcome one, and will form the nucleus for a bee- 
keeping library which will be available not only to the scientific workers 
in apiculture in the Southern States but to beekeepers as well. 
Visitors at the laboratory in June included Henry Brown, of Cape May 
Court House, N. J., one of the most prominent commercial beekeepers in New 
Jersey, and Aubrey V. Smith, of Phoenix, Ariz., also a prominent commercial 
beekeeper. 
The Press Service announced on May 31 that arrangements had been made 
to include chemical tests of honey where official United States certificates 
of grade are desired. At the present time these tests will be made by the 
food—-products inspection service of the Bureau of Agricultural Economics. 
This arrangement does not apply to samples which are graded, without charge, 
merely for color, but to lots which are to have certificates of inspection. 
The press release should be consulted for further details.
