BEE CULTURE 
The Maryland State Beekeepers' Association held its annual summer 
meeting at the Somerset, Md., laboratory on June 20. Various members of 
the laboratory staff participated in the meeting. 
At the Bee Culture Laboratory, Somerset, Md., work was begun in 
June on measuring the flight activity of the honeybee by means of photo-— 
electric cells. Representatives of the American Instrument Company vis- 
ited the Bee Culture Laboratory at Somerset on July 15 to demenstrate 
the use of their apparatus in making counts of the flight activity of the 
honeybee by means of photoelectric relays. 
A study of the vitamin requirements of the honeybee and of. the 
“nitrogen changes in the body of the worker bee during life under normal 
and artificial conditions was also taken up. 
J. E. Eckert, of the Intermountain States Bee Culture Field Labo- 
ratory, Laramie, Wyo., has renewed his studies on the effect of distance 
from a source of nectar on the production of honey. A new project being 
carried out by Dr. Eckert and Russel Smith, Field Assistant, has been 
started to determine the nectar and pollen plants in the vicinity of 
Laramie, together with the relative importance of each and their time of 
blooming. The third project being planned by Dr. A. P. Sturtevant and 
Doctor Eckert is to determine how far bees will fly to rob other hives. 
The specialists have in mind the question of the spread of American foul- 
brood. 
The cooperative project between the Laramie laboratory and the Wy- 
oming Experiment Station on the carbon dioxide metabolism of the honey- 
bee was ended on June 30. 
The apiary at Laramie now consists of 44 full colonies and 10 new 
colonies made up from packages of Caucasian bees received on June ll. 
A report to this office from the Pacific Coast Bee Culture Field 
Laboratory, Davis, Calif., states that warm weather has started nectar 
secretion in the mountains up to 7,000 feet. A small amount of honey 
was coming in from star thistle, except in the valleys where the weather 
has been hot and too dry for this plant. 
A queen of the Pacific Coast Black bees, supposedly of stock in- 
troduced by the Russians during their occupation of California, and 
which was secured by E. L. Sechrist and Frank E. Todd in the Coast moun- 
tains, has been introduced into a colony at the Davis, Calif., labora- 
tory and is building up the colony successfully.
