EXPERDIEXT STATION, 



[Jan. 



Diagnosis of Ixsect Troubles. 

 During the year ending the last of November, 1921, diag- 

 nosis of 616 cases of insect injury were made on insects and 

 insect damage reported from 226 different villages, towns and 

 cities in the Commonwealth. In addition to this there were 

 222 telephone or ofSce calls on the same subject, and 39 visits 

 by members of the staff at the request of owners, as well as a 

 large amount of miscellaneous correspondence relating to in- 

 secticides and spray machinery. This again is a service which 

 has no commercial counterpart, and which must be rendered 

 by the station or not at all. Farmers as individuals, moreover, 

 are unable oftentimes to either recognize or combat such 

 troubles. Apparently, therefore, the Experiment Station must 

 continue to give this service. The following table is presented, 

 showing the range of subjects treated in this work, and the 

 geographical range from which inquiries come: —

 from the town; where there is no figure only one case of injury was reported.]
