December, '11] SANDERSON: ENTOMOLOGICAL INVESTIGATIONS 537 



The replies which have been received to date CNovember 5) are ar- 

 ranged h)elow according to subjects. Some ten or twelve correspond- 

 ents are still to be lieard from and their replies will be prepared in 

 similar form and published in the next issue. 



In the following list the letter before the name of the proje(;t indicates 

 the fund under which it is carried on, insofar as the funds were indicated 

 by the correspondent; (A) is for Adams Fund, (H) for Hatch Fund, and 

 (S) for State Funds. In many cases where the entomologist of the 

 experiment station is also state entomologist, it was not possible to 

 determine from the replies made whether the project was carried on 

 under experiment station funds or state appropriations. In many 

 cases the correspondent failed to give the names of assistants carrying 

 on certain lines of work, in which cases the statement is made to that 

 effect. 



This preliminary report is pubhshed at this time so that it may 

 furnish the basis for conferences between those workers who are 

 prosecuting similar investigations at the Washington meeting of the 

 Association. The committee expect to present their final report at 



that meeting.
