M. C. Swingle and J. F. Cooper, at Sanford, Fla., are testing 
fixed nicotine dusts against newly hatched larvae cf the imported 
cabbage worm (Ascia rapee L.), the greenhouse leaf tier (Phlycteenia 
rubigalis Guen.), and the southern armyworm (Prodenia eridania Cran.). 
Of these three species, the cabbage worm is the most susceptible to 
nicotine. Nicotine silicotungstate again showed considerable toxi- 
city to the armyworm. 
F. L. Campbell ana W. N. Sullivan, Takoma Park, have found that 
their laboratory method for testing; kerosene sprays against house 
flies gives results in good agreement with those previously obtained 
with the same samples of pyrethrum—kerosene by others who used the 
Peet—Gratly method. In the course of these tests they confirmed Mel-— 
vin's revort that male house flies are more susceptible to pyrethrum— 
kerosene sprays than are females.

United States, having a floor space of about 10 acres. The apiary 
exhibits occupied two entire sections of this building and were di-
