The Brown-Tail Moth. 



(Eiiproctis chrisorrhoea. ) 



This moth has had a noted history in the entomological litera- 

 ture of Europe for the past 300 years. 



A single egg-cluster, or a winter nest was imported from 

 Holland about the year 1890, to Somerville, Mass. From the 

 above as a nucleus, this noted pest has extended its domain until 

 at tJie present time it stands as a menace to five out of the six 

 New England States. 



The work done by our cities, towns and private individuals 

 during the campaign of last year was highly creditable to the 

 public spirited enthusiasm of our loyal citizens, but it will never 

 do to stop here. 



AREA INFESTED IN I906. 



The area established in 1905 extended over about 4,000 square 

 miles. York and Cumberland counties were entirely infested 

 except two or three towns in the northwestern part. 



Sagadahoc county was entirely infested. 



One town in Oxford county, the southern portions of Andros- 

 coggin and Kennebec counties, the most of Knox and Lincoln, 

 seven towns in Waldo, and from Bucksport in Hancock county 

 to Columbia Falls in Washington county. 



The spread along the northern boundary has been principally 

 on the western half ; while east of Bucksport there has been 

 but a very slight northern spread. 



At the close of this year, 1906, the whole of York, Cumber- 

 land, Androscoggin, Sagadahoc, Lincoln and Knox counties 

 were infested. The following towns in Oxford county were 

 more or less infested: Porter, Hiram, Brownfield, Sweden, 

 Waterford, Norway, Hebron, Paris, Buckfield, Hartford, Sum- 

 ner and Woodstock. 



One nest was taken at Wilton ; this was the only nest reported 

 in Franklin county. 



In Kennebec county in addition to last year's infestation a 

 few nests were taken in Fayette, Readfield, Mount Vernon, Bel- 

 grade, Monmouth, Sidney, Waterville, Vassalboro, China and 

 one nest in Winslow. 



In Waldo county the northern boundary of infestation 

 extends through the towns of Liberty, Searsmont, Belmont,
