holding- the outbreak in check and on July 8th many flesh flies 

 iSai'cop/iaga) were seen and from this day on, jDeriodically, they 

 were found in great abundance wherever the grasshoppers occurred. 

 Large numbers of dead grasshoppers were found on the ground and 

 many examinations revealed that the maggots were in the grasshop- 

 pers in great numbers. There is much reason to believe that, if this 

 outj^reak fails to develop into a seriously extensive one, it will be 

 due to these flies which appeared in innumerable number^, depositing 

 young maggots on the adult insects. 



EGGS IN THE FALL 



Assistants w^ere sent to the region in the fall who made thorough 

 surveys for e\'idence of egg-laying, for it was desired to know if we 

 were to have a recurrence of the grasshopper outbreak in 1918. 

 Through several days of searching no grasshopper eggs whatever 

 were found and from this fact it is hoped that there will not be any 

 serious trouble next season.
