during the previous winter. Probably many of these scattered 

 eggs are responsible for the large number of single infestations 

 through the towns of Kittery and Eliot. 



In the work in Massachusetts during the old commission an 

 experiment was tried to determine the vitality of the gipsy eggs 

 when subjected to the process of freezing. and thawing. Egg- 

 clusters were placed in water and put through this process for 

 several successive periods and quite a per cent of them hatched, 

 showing that the ordinary freezing and thawing does not 

 destroy their vitality. 



Fifteen trees in the orchard were burlapped during the sum- 

 mer. The burlaps were carefully tended and every precaution 

 taken to get rid of the pest. A few larvae wer^ taken which 

 probably hatched from scattered eggs. From the results shown 

 it aj^peared that the scouts were successful in finding all of the 

 egg-clusters. This place is situated away from the main trav- 

 eled road. After the burlapping season was over the place was 

 thoroughly cleaned up; the leanto was removed and all trees 

 pruned, scraped and tin-patched so that everything around the 

 place is in first class condition for next summer's work. A few 

 egg-clusters were found during the fall scout in an orchard back 

 of the house but not near enough to have been associated with 

 this infestation. 



Plate X. This represents the Capt. Glenn place at York 

 Harbor. The infestation was discovered by the government 

 scouts in November, 1906. Thirty-six egg-clusters were 

 found ; some in apple trees ; under walks ; in decorative rock 

 piles ; about the lawn used for summer flower gardens ; etc. 



This is a summer hotel situated on the main traveled road 

 just opposite the post office at York Harbor. Here hundreds 

 of autos pass by daily during the entire summer. They begin 

 early in Alay so they would be coming during the whole cater- 

 pillar season. 



In April this same place was thoroughly scouted by the State 

 men and sixteen more egg-clusters were found, making fifty-two 

 in all. Four were under a plank walk ; four in a rock pile ; four 

 in a coal shed ; one in a box ; one in an apple tree ; one on the 

 under side of a wash-bench, and one on a piece of plate glass 

 which was standing against the side of the shed. On opening 

 the door of the coal shed a cluster was found on the inside so
