WORK OF GYPSY MOTH COMMISSION IN 1906 



It gives me great pleasure to meet you today. Last 

 year it was because of business and this year it is sickness 

 that prevents Prof. Kirkland from meeting you. 



The time is so short I will read a few statements al- 

 though I prefer to speak from my own knowledge of the 

 progress of the work during the past year. 



During the season of 1907 we have added 5 towns to our 

 territory. The diagrams show the territory infested from 

 1900 to the present time. 



There are 144 cities and towns infested with the gypsy 

 moth and 67 more that are infested with the brown tail 

 making a total of 211 infested cities and towns in the state. 

 This infested territory covers an area of 2500 square miles 

 or 75 per cent, of the taxable property of the state. $315,000 

 has been expended by the state, cities and towns during the 

 past year and about the same amount by individuals, mak- 

 ing about $750,000 expended in the state of Massachusetts 

 during the past year in killing these two pesta. 



Last year an effort was made to introduce European 

 parasites of the moth, which cost about $10,000. 



The policy of the year's work was to check the spread- 

 ing of the moth by killing along the roadsides, burlapping 

 and spraying the trees. 1200 men were employed and 

 8000 miles of streets cared for. The same body of men was 

 employed in freeing the thickly settled portions of the in- 

 fested districts. 90 per cent, of the thickly settled resi- 

 dential districts were so thoroughly cared for that there was 

 very little trouble from the moths. 



The work has been hindered by the failure of certain
