GENERAL RESULTS SHOWN BY SCOUTING WORK. 



The scouting work for the season has shown very encouraging 

 results. In addition to the large number of towns along the outside 

 border where the infestation has been greatly reduced or where it has 

 been cleaned out during the past year, an excellent showing has been 

 made in a number of badly infested towns in Massachusetts and New 

 Hampshire which are just inside the border. In a large number of 

 these towns which were found severely infested in the winter of 

 1912-13, a large decrease in the number of egg clusters has been found 

 this year. In the town of Bradford, N. H., where over 3,000 egg 

 clusters were treated during the former year, only 200 were found this 

 season. In Hillsboro the records show a reduction of from 8,000 to 

 500, although the number of small colonies, many containing a single 

 egg cluster, has increased. In Henniker and Warner, N. H., a large 

 decrease has also been noted and the same is generally true in the 

 border towns where work is being carried on. 



The work on the tanglefoot bands during the entire season gave 

 very gratifying results, and a very large number of the colonies where 

 caterpillars were present early in the season showed no caterpillars 

 or pupse at the close of the work on tanglefoot bands on August 1. 

 Only a few caterpillars were found in the western part of the area in 

 New Hampshire, Rhode Island, and Connecticut. 



No caterpillars were found in Lenox, Stockbridge, or Great Bar- 

 rington, Mass. About 400 yards from the old infested area in the 

 latter town 43 egg clusters were found in a rock heap during the cater- 

 pillar season which, of course, was under the snow when scouting 

 work was done. Some very thorough work was done at this infesta- 

 tion, and only one pupa was found this season. Of course there is 

 danger of some spread from it, and during the coming season some 

 very thorough scouting will be done in this vicinity. 



No caterpillars were found at Wallingford, Conn., this season. 



In the badly infested woodland colony in Orange, Mass., where 

 some 1,000 egg clusters were located, there were but 1,182 larvse 

 found during the summer. 



The spraying work during the summer gave very satisfactory 

 results, treatment being applied in border towns from Hubbardston, 

 Mass., as far north as Andover, N. H. Many of the localities where 

 spraying was applied were difficult to reach on account of being 

 inaccessible from roads or water supply, but owing to the careful plans 

 made by the foremen the work was not greatly handicapped on this 

 account. In a number of cases the owners of the areas which were 

 infested offered every cooperation possible in facilitating treatment. 

 A few cases have been found, however, where spraying could not be 

 attempted on account of the unwillingness of the owners to have their 

 pasture trees treated because the grass was needed for grazing stock. 

 In instances of this sort the infestations were cared for by creosoting 

 egg clusters and destroying the caterpillars under tanglefoot bands.
