"which combs the pollen from the legs of the bees as they enter the hive 
* * *. Some 2,000 to 3,000 samples of pollen pellets are now being tak-— 
en during the day twice a week. Of the samples collected, yellow and 
white sweet clover count for about 75 per cent of the total number of 
samples. Other pollen is being collected but in much smaller amounts 
from cleom, white Dutch clover, and dandelion. * * * The bees have been 
found to collect certain kinds of pollen during certain hours of the day. 
* * * The blooming periods of plants are being determined by the collec-— 
tion and identification of the pollen at the hive. An extensive collec-— 
tion of plants is being made at the same time and permanent mounts of the 
pollen from each plant are being made to assist in the identification of 
the pollen collected at the hive and to determine the nectar and pollen 
plants in the vicinity of the apiary." 
Warren Whitcomb, jr., in charge of the Baton Rouge, La., sub- 
laboratory, reports that, contrary to the common conception, white clover 
in certain parts of the South produced nectar abundantly this year. 
White clover is usually considered strictly a northern honey plant. 
E. L. Sechrist, acting in charge of the Davis, Calif., sublab- 
oratory, reports a severe loss of bees in the buckeye region. Requeening, 
where it was tried, was apparently not efficacious in stemming the death 
of bees. and in order to save some of the experimental colonies it was 
necessary to give new queens and add fresh bees. In experiments conduct— 
ed at Davis, with colonies under control, it was found that both the 
honey and pollen from buckeye have a serious effect upon brood rearing.
