38 THE GYPSY MOTH. 



1897, and it was here that most of the moths found were 

 killed. These woods became infested because of their near- 

 ness to infested woods just over the line in Saugus and Mai- 

 den. "Early in the season this tract was looked over and a 

 considerable portion of the underbrush cut out and burned. 

 The trees were burlapped and attended through the summer. 

 Although the town has had no inspection during the fall, 

 winter or spring for several years, most of the residential 

 portions, including all the known colonies outside of the 

 woodland before mentioned, were gone over -either in 1895 

 or 1896, and for three years nearly all the trees in town 

 have been burlapped each summer and well attended, so that 

 it has been kept in excellent condition ; but its situation is 

 close to the central infested towns, and thousands of people 

 travel from them to the Revere beaches during the summer.

On this account the moth will probably be found in Revere 

 so long as the central towns continue to be infested. 



Salem. 



All but two of the old colonies in the business and residential 

 part of Salem appear to have been exterminated. In one of 

 these colonies all the eggs which were found in the winter 

 of 1896-97 were destroyed. In the summer of 1897 cater- 

 pillars were taken here. In the fall inspection two egg- 

 clusters were found in the other colony. 



In the Salem pastures many colonies of gypsy moths have 

 formerly been found. The vegetation on this tract consists 

 largely of red cedar interspersed with hard-wood trees, and 

 the ground is overgrown with barberry bushes and ground

juniper. The density of this growth renders a thorough 

 search for eggs impossible, but the young caterpillars can 

 readily be found on the low foliage. A search of a large 

 portion of the pastures was made during the spring, and 

 wherever caterpillars were found most of the trees were cut 

 and the ground and undergrowth burned over with oil. 

 Apparently this has exterminated the caterpillars from most 

 of these pasture colonies ; but this region will need a careful 

 watching for some years. 



Most of the different forms of the moth found in Salem in 

 1897 were taken in the pastures.
