J. 3. Mabee (June 17): Mosquitoes, A^des dor sal is arid others, 
are beginning to emerge in large nu^flsers practically all over the 
State. The control campaign at Chinook ard Malta is "being ren- 
dered considerably more difficult by the high water of the Milk 
River which has covered practically the -hole valley and will de- 
lay control operations. Indications are that mosquitoes will be 
considerably more of an economic problem this year than ever 
before.

SCRE',7 WORM ( Cochliomyia macellaria Fab.) 
E. C. Sishopp (hay 2c) : During Lay many complaints of .an unusual 
number of screw-worm cases have come t o this office. It appears 
that the screw worm conditions are considerably worse than the 
average for this time of the year. Much interest is manifested in 
fiytrapping campaigns, and several of the county agents are aid-
