6 INTRODUCTORY. 



dition and more promising from actual results at the present 

 time than ever. 



The State Forester cannot refrain from saying also that what 

 Massachusetts is doing in this work is indirectly as important 

 to the nation generally ; for what is here accomplished will ulti- 

 mately result in equal value throughout 'New England and 

 finally elsewhere. 



ACKNOWLEDGMENTS. 



The work of writing and compiling the data in this bulletin 

 was done by Mr. W. F. Fiske, agent and expert, Bureau of 

 Entomology, United States Department of Agriculture, in 

 charge of directing the technical work of introducing the para- 

 sites and predatory enemies of the gypsy moth and the brown- 

 tail moth into Massachusetts. The headquarters for this work 

 are at the State laboratory at Melrose Highlands. 



When it was determined by the State Forester that the in- 

 formation contained in this bulletin would be appreciated by our 

 people, a conference with Dr. L. 0. Howard, the United States 

 Government Entomologist, who has been our chief adviser in 

 expending the State's money for this work, resulted in his dele- 

 gating Mr. Fiske to the task. Mr. Fiske's manuscript was ex- 

 amined and approved by Dr. Howard. 



We are therefore under obligations to both of the above-named 

 gentlemen for their hearty co-operative efforts in our behalf. 



F. W. EANE, 



State Forester.
