REPORT OF STATE ENTOMOLOGIST. 255 



by ground scouting and shows that they probably were brought 

 across on the drift wood, etc., and were so nearly grown as to 

 pupate at once on the ground and the female laid her eggs on the 

 leaves and twigs, while on the Thaxter place just across the 

 river most of the egg-clusters were found on the trees. This 

 area, embracing the four estates, covers about one hundred and 

 fifty acres. Only a superficial scout had been made, but the 

 whole territory will be put into first class condition for the sum- 

 mer campaign. 



Plate XV shows the Thaxter infestation situated between 

 Brave Boat Harbor and Cutts Island taken at a distance to show 

 the outline of the largest infestation as yet discovered in the 

 state. This shows only the Thaxter woods where 3,356 egg- 

 clusters were taken. 



This infestation was discovered by one of the scouts. He 

 was going from the Thaxter infestation on Cutts Island to the 

 Brave Boat Harbor road so took a short cut across the pasture 

 and as he entered the woods he noticed an egg-cluster on a pine 

 tree. Investigation was immediately begun which resulted in 

 finding that the entire wood lot was infested. 



This woodland consists of about three hundred acres and is 

 owned by about twenty different parties. A thorough scout 

 was made covering almost the entire area. 4,179 egg-clusters 

 were taken in this tract of woods. (The other lots are not 

 shown in this cut.) Four crews of men were put into the wood 

 for the purpose of clearing up ready for next season's work. 



About one hundred acres have been gone over ; trees thinned 

 out ; brush raked up and" burned ; in fact the ground has been 

 gone carefully over and cleaned thoroughly. 



Plate XVI shows a portion of the Thaxter woods after the 

 clearing and cutting out. 



Had these woodland colonies been discovered last year much 

 greater progress would have been made in the work of extermi- 

 nation. As it is we are up against a serious problem in this 

 section and it will require a larger force to handle the infesta- 

 tions in this section than all of the rest put together. 



These woodland colonies are the ones to be dreaded as it will 

 necessitate the burlapping of a large number of trees and in 

 some cases spraying may have to be resorted to, which is the
