hope, have not proved very favorable, while experiments with a large 
series of other vegetable insecticides have given no practical results 
as yet. 
The experiments with contagious diseases can not be reported upon 
in any detail at the present time; but a large number of cultures of 
several diseases of the Imported Cabbage Worm, the Bronzy Cutworm 
and of two other Noctuids have been secured and carried through the 
winter. What may prove to be a specific disease of the Boll Worm 
has also been discovered, and cultures have been obtained. It results 
from the few experiments made that the Boll Worm is probably sus- 
ceptible to the Cabbage Worm disease, but positive statements can 
not be made until these experiments are confirmed by those of another 
season. A bacteriological laboratory has been established at Shreve- 
port, Louisiana, and has been well fitted out with the necessary 
apparatus, so that work in this direction the coming season will not 
be hampered, except in the case of an unexpected paucity of Boll 
Worms.
