weight, and contained 0.138 milligram of sugar as glucose, or 1 per cent. 
A larva that weighed 13.20 milligrams contained 0.435 milligram of glyco-— 
gen by weight, or 3 per cent, and 0.3744 milligram when determined as 
glucose, or 2 per cent. A comparison of the two species, therefore, 
shows that C. pomonella weighs abcut four times as much as A. comptana 
but its water content is ll per cent less and its fat content 1P@per 
cent more. Its sugar content as gluccse is 0.5 per cent less ard ats 
glycogen content 1 per cent less than in A. comptana." 
BEE CULTURE 
To present the life of the bee adequately and to show the part it 
plays in honey and wax prcduction and in pollination, James I. Hamble- 
ton, in charge of the Bee Culture Laboratory, Somerset, Nd., in cooper— 
ation with the Motion Picture Laboratory of the Department, began work 
two years ago on a motion picture film. This film, "The Realm of the 
Honeybee," has now been completed and was shown to Bureau workers in 
December. Nearly all of the scenes were taken at the Bee Culture Labor— 
atory at Somerset, Md. Those on the use of honey in cooking, however, 
were taken in the experimental kitchens of the Bureau of Home Economics, 
and the scenes on pollination were taken in commercial orchards in upper 
Maryland. By use of slow motion sections, interesting details of collec-— 
tion of pollen and other activities and behavior, practically beyond the 
grasp of ordinary vision, are clearly depicted. The public interest in 
a highly educational film of this type has already been indicated by the 
almost constant use that has been made of the beekeeping films put cut 
by the Department nearly 10 years ago. 
In the December number of the Monthly Letter reference was made to 
the isolation by C. E. Burnside, Somerset, Md., of an organism which ap— 
pears to be closely related to Bacillus alvei Cheyne. Mr. Hambleton 
now reports that Mr. Sturtevant, from material submitted to him, has 
verified the results obtained by Mr. Burnside in that he was able, not 
only to differentiate the form in culture, but also to detect morpholog— 
ical differences and differences in staining quality. Therefore, it ap- 
pears that there is little question that the organism is not the common- 
ly encountered strain of Bacillus alvei. 
E. L. Sechrist, Davis, Calif., made a trip in December tO the 
Eldorado County fruit district, where he met, he says, "a number of fruit 
growers from whom data on fruit and pollination could be obtained, and 
plans formulated for completing the securing of such information. One 
grower in this territory has 400 Wickson plum trees. They have been in 
bearing age 4 to 5 years, never yielding over 125 boxes of fruit up to 
19351. No trees of pollenizing varieties were present, with the excep— 
tion of one Climax tree. The owner had always noticed that around this 
Climax tree he secured most of his plums. He grafted into the Wickson 
trees some Formosa plum scions. Nineteen hundred and thirty-one was the
