It is intended in this report to give a short historic account of the gypsy and brown-tail moths and their occurrence in this country, together with a description and life history of both insects. A detailed account of methods of work employed and the various expenditures will also be given.

This seems quite essential in order that the many of our private citizens who realize the great menace of the presence of these pests, and who individually wish to do all in their power to help in exterminating or suppressing them, may have an intelligent understanding of their nature and of the methods of procedure against them. According to the resolution the Commissioner is responsible to the Governor of the State for the proper execution of his work, and it is with sincere respect that the writer acknowledges the generous encouragement which His Excellency, Governor Utter, has at all times given to the work, and the plain, straightforward manner in which he has given his counsel regarding such questions as came to him for attention and decision. The writer is under great obligations to the Board of Managers of the Rhode Island College and to Presidents Butterfield and Edwards for every encouragement in the prosecution of this work. To Dr. Wheeler, director of the Rhode Island Experiment Station, is due sincere acknowledgment for suggestions as to plans for the campaign. To him also is no doubt due the credit of having put forth. the greatest efforts toward creating a public sentiment favorable to an appropriation in this State, and of having done much effective |
