ENTOMOLOGY. 



Experiments in beekeeping, O. J. Lowrey, M. F. Cram, and 

 H. W. Scott (Vermont Sta. R^ft. 1891, pp. 136-140). — Tins consists of 

 notes on experiments with bees and honey carried out under the general 

 direction of the Vermont Beekeepers' Association. 



Seventeen hives were phiced in a room 6 by 24 ft., capable of accom- 

 modating 24 colonies. The bees having come from different sources 

 were in different sized frames, and for this reason were observed closely 

 to determine tlie best form of frame to adopt in the production of comb 

 or extracted honey and for wintering bees. No perceptible difference 

 has yet been noticed. 



After the onset of frost, sugar sirup was fed in different ways to test 

 the ability of bees to change cane sugar into honey sugar. Analyses 

 are given of the honeys i)roduced, pure honey, and honey that had been 

 adulterated with cane sugar. It was found that the best honey was 

 l)roduced when a large quantity of sirup was fed to the bees rapidly. 

 The resulting honey did not graiuilate. When sirup was fed in small 

 quantities for a considerable time less sucrose was found on analysis,
