 report. 



The parasite work has already begun to show very good 

 results, as must be evidenced by all casual observers. Partic- 

 ularly is this true in the case of the imported calosoma beetle, 

 which, in both the adult or beetle and the larval stages, was 

 extremely numerous this past year. In neglected woodlands, 

 where the moths were bad, the writer is of the opinion that the 

 calosoma destroyed at least one-tenth of the motlas present. 

 Other parasites are reported upon elsewhere by Dr. L. O. Howard, 

 United States Entomologist, who has co-operated with us. 



Of the mechanical methods of suppression, spraying with 

 arsenate of lead is still one of the great factors in our hands for 

 ameliorating conditions. Several more towns have added high- 

 power spraying machines during the year. 



Approximately 750 tons of arsenate of lead were used 

 throughout the season. The Metropolitan Water and Sewerage 

 Board purchased an auto truck sprayer the past season, which 

 makes the third now in use. 



The plans for enlarging the output from our nurseries, 

 through utilizing the labor of some of our State penal institu- 

 tions, are very promising indeed. Three acres of transplant 

 stock were set out on land turned over to the State Forester 

 for this purpose on the land of the State Farm at Bridgewater 

 this fall, and Captain Blackstone, the superintendent of the 

 institution, has promised us enough more land to make 10 acres 

 in all by next spring. 



The Foxborough State Hospital is also preparing a plot for 

 a nursery on a very conspicuous site along the State high- 

 way at Norfolk, and it is believed this institution, through its 

 being able to co-operate in aiding the State in the work of 

 reforestation, can render splendid service to the State. Dr. 

 Neff, the superintendent, and the board of trustees are all 

 very enthusiastic over the undertaking. The State Forester's 

 nursery at Amherst is as great a success as ever, and our total 

 capacity is estimated at about 7,000,000 seedlings and trans- 

 plants at the present time. We have donated several hundred 

 thousand to various State institutions, as the nursery report will 

 show. This is printed elsewhere in the report.
