state insect pest reporter for Indiana and takes this opportunity of 
requesting the co-operation of every member of this Academy in sub-

the state who care to co-operate in this work are requested to advise 
us. They will be furnished with data sheets and franked envelopes so 
that no expense in collecting or sending in the information will be 
involved. Purdue University.
